Sugar. 20 Things You Didn't Know About

We eat it, we love it, and it may have been a chemical precursor to life on Earth.

1 The average American eats 61 pounds of refined sugar each year, including 25 pounds of candy. Halloween accounts for at least two pounds of that.

image 2 Trick: Sugar may give you wrinkles via a process called glycation, in which excess blood sugar binds to collagen in the skin, making it less elastic.

3 Or treat: Cutting back on sugar may help your skin retain its flexibility. So actually, no treats.

4 People in India have been crystallizing cane sugar for at least 2,000 years. When Alexander the Great’s companions arrived there, they marveled at the production of honey without bees.

5 In 1747 German chemist Andreas Marggraf discovered that the sugar in a sugar beet is identical to that in sugarcane. In 1802 the first beet-sugar refinery began operations, bringing cheap sweets to northern climes.

6 More than half the 8.4 million metric tons of sugar produced annually in the United States comes from beets.

7 Can you imagine eating 8 sugar cubes (8 spoons of sugar) at one sitting? You probably have. That’s a little less than what is contained in a coke or Pepsi (~ 300 ml).

8 Soft drinks with artificial sweeteners may actually help make you fat. In a Purdue University study, rats drinking liquids with artificial sweeteners consumed more calories overall than rats whose drinks were sweetened with sugar.

9 The artificial sweeteners saccharin and aspartame were found accidentally when lab workers doing research that had nothing to do with sweetening put a bit of the test compounds in their mouths and liked what they tasted.

10 What kind of researcher sticks an experiment in his mouth?

11 At least he had an excuse. The scientists who discovered sucralose (now sold as Splenda) were originally trying to create an insecticide. An assistant thought he had been instructed to “taste” a compound he’d only been asked to “test.”

12 A compound called lugduname is the sweetest compound known—more than 200,000 times as sweet as table sugar.

13 Sugars are molecules of carbon, hydrogen, and oxygen. The simplest include glucose, fructose, and galactose. Table sugar is crystallized sucrose, a fusion of one fructose and one glucose molecule.

14 Can’t escape them: Sugars are the building blocks of carbohydrates, the most abundant type of organic molecules in living things.

15 Glycolaldehyde, an eight-atom sugar, has even been found in an interstellar gas cloud near the center of the Milky Way.

16 Glycolaldehyde can react with a three-carbon sugar to form ribose, the basis for both RNA and DNA, so the glycol­aldehyde found in deep space may be a chemical precursor to life on Earth.

17 That cloud also contains ethylene glycol, a sweet relative of glycol­aldehyde and the main ingredient in antifreeze. Either complex sugars can be synthesized between the stars or there is a truck stop at the end of the universe.

18 Sugar can help get you there to find out. Burn sucrose with a dose of corn syrup and saltpeter and you get “sugar propellant,” a popular amateur rocket fuel.

19 How do you spell relief? “Obecalp,” a sugar pill manufactured to FDA standards, is marketed as a treatment for children’s mild complaints. (Try reading the name backward.)

20 It’s not all mind games. The sugar glucosamine works as an immunosuppressant in mice, and xylitol (a sugar alcohol) can prevent ear infections in kids. Sweet!

Bio-Degradable USB stick

Hong Kong-based Hoshino, released of what it's designated "the world's first bio-degradable USB disk."

The key is also shaped like an ear of corn, so you can acknowledge your own greenness, every time you go to retrieve information.

It is made of polylactide(PLA). PLA uses annually renewable plant resources (corn) as raw material, which is fermented and distillated to produce lactic acid.

Followed by the process of dehydration polymerization, high-temp depolymerization, refining and finally polymerization, lactic acid is then transformed to PLA. Its products can be degraded to carbon dioxide and water by microorganisms in the soil after use and do no harm to the environment.

Plant Grows at high Temperatures with help of Fungi/Virus

Let us talk about three new things I didn't know till now. Hope it will be informative or useful for your entrance exams.
1. Dichanthelium lanuginosum is grass plant known as Panic grass* and was able to survive intermittent high temperatures in geothermal soils (up to 65 °C.) of Yellowstone National Park, USA.
2. In 2007 it was found that the heat tolerance is conferred to the grass due to its association with an endophytic fungus, Curvularia protuberata.
3. "Thermal Tolerance" trait conferred by the endophytic fungus is actually due to a specific RNA virus onboard. This dsRNA virus is aptly named "Curvularia thermal tolerance virus" (CThTV). Infected fungal mycelia contain two viral dsRNA molecules: a 2.2 kb dsRNA molecule that encodes two ORFs related to viral replication and a 1.8 kb dsRNA molecule with two ORFs with no similarity to any protein of known function.
As we all know virus is pathogenic. CThTV is Symbiotic.
This is an example of a tritrophic interaction, as three organisms are interacting.
Panic Grass
Work is continuing to determine the mechanism by which the uncharacterized ORFs within the 1.8 dsRNA of CThTV confer the thermal tolerance in this fungal-plant mutualism.
*Panic grass, incidentally, has nothing to do with botanical phobias; instead, the name derives from the Latin panicum, referring to foxtail millet.

Ready to Eat Rice without cooking !

Yes. Scientists of Central Rice Research Institute (CRRI), developed new rice variant named "Aghaono Bora", a soft rice or komal chawl, takes 45 minutes if soaked in normal water and if the water is lukewarm, it is ready in 15 minutes.

However, the soft rice varieties grown across Assam and the North-East, are ready to eat after they are soaked in plain water. it is a low-yielding crop that grows only in a cool climate.

Aghaono Bora | Ready to Eat Rice

The Scientists from CRRI, one of the premier research institutes on grains in the world, developed a hybrid of traditional soft rice with a high yielding variety of regular rice, that could be grown in different climates across India.

"We wanted to see whether the same rice can be grown here and retain the same properties. We saw it behaves the same way. Simply soak it in water and the rice is ready to eat but the quality of water has to be clean and potable. The idea is to avoid any waterborne disease," said Tapan Kumar Adhya, director, CRRI.
“This rice variety, which comes under soft rice category, helps in saving fuel as it doesn’t require any boiling ,” said Tapan Kumar Adhya.

In Orissa where 'pakhal' or cooked rice fermented in water is a hot favorite, the soft rice is expected to be a hit. It's environment-friendly and will save a huge amount of fuel and time.

Transparent Frog, First see-through frog

Professor Masayuki Sumida, Research Team @ Hiroshima University’s Institute for Amphibian Biology has created a  transparent frog whose internal organs are visible through its skin.

I can see you, and your intestine

The researchers say the see-through frogs can help in the study of diseases and in the development of medical treatments by allowing laboratory scientists to check the status of internal organs and blood vessels while the frogs are alive and without having to dissect them.

Translucent frog --

According to Sumida, the transparent frog is the result of breeding two specimens of Japanese brown frog (Rana japonica) that had a genetic mutation giving them pale skin. By selectively breeding their offspring, the researchers were able to create a frog that remains transparent for its entire life cycle.

Most of the world’s known transparent creatures live underwater, and transparent four-legged animals are extremely rare.

The researchers also say that by fusing the genes of fluorescent proteins to the frog’s genes, they can create frogs that glow. Glowing frogs can help scientists study specific “problem” genes by providing a real-time visual indication (i.e. the frogs glow) when those genes become active.

Professor Sumida says, “Transparent frogs will prove useful as laboratory animals because they make it easier and cheaper to observe the development and progress of cancer, the growth and aging of internal organs, and the effects of chemicals on organs.”

Buddha shaped Pears

Gao Xianzhang has managed to create what some would call the holiest fruits ever, pears shaped like Buddha.

buddha-pears

buddha-pears3

Gao has been working on his pear-growing technique for six years and this season he managed to grow 10,000 Buddha-shaped baby pears. Each fruit is grown in an intricate Buddha mould and ends up looking like a juicy figurine. The ingenious farmer says the locals in his home village of Hexia, norther China, have been buying his Buddha pears as soon as he picks them from the trees. Most of them think they are cute and that they bring good luck.

Gao Xianzhang pears aren’t cheap, roughly $1.8 each, but their success in China convinced him to start exporting them into Europe.

Square Watermelons! It's true.

Farmers in the southern Japanese town of Zentsuji have figured out how to grow their watermelons so they turn out square.

watermelon1

watermelon2

watermelon3 It's not a fad. The technique actually has practical applications. "The reason they're doing this in Japan is because of lack of space," said Samantha Winters of the National Watermelon Promotion Board in Orlando, Florida.

A fat, round watermelon can take up a lot of room in a refrigerator, and the usually round fruit often sits awkwardly on refrigerator shelves. But clever Japanese farmers have solved this dilemma by forcing their watermelons to grow into a square shape.

Farmers insert the melons into square, tempered glass cases while the fruit is still growing on the vine.

The square boxes are the exact dimensions of Japanese refrigerators, allowing full-grown watermelons to fit conveniently and precisely onto refrigerator shelves.

But cubic fruit comes with a price: Each square watermelon costs 10,000 yen, the equivalent of about $82. Regular watermelons in Japan cost from $15 to $25 each.

Japanese farmers have perfected the art of growing square watermelons, but they aren’t about to reveal their secret process. When a square watermelon sells for $82 who can blame them.

Self-Irrigating Desert Plant Discovered

A desert plant has apparently figured out how to water itself.

Ecologists had been puzzling over the desert rhubarb for years: Instead of the tiny, spiky leaves found on most desert plants, this rare rhubarb boasts lush green leaves up to a meter wide.

Now scientists from the University of Haifa-Oranim in Israel have discovered that ridges in the plant’s giant leaves actually collect water and channel it down to the plant’s root system, harvesting up to 16 times more water than any other plant in the region.

“It is the first example of a self-irrigating plant,” said plant biologist Gidi Ne’eman, a co-author on the paper published in March in Naturwissenschaften, a German journal of ecology. “This is the only case we know, but in other places in the world there might be additional plants that use the same adaptions.”

The desert rhubarb grows in the mountainous deserts of Israel and Jordan, where there’s only about 75mm of rainfall each year. Even during the rainy season, the region’s light rainfalls often don’t penetrate the rocky soil of the desert. Plants with large leaves and a deep root system, like the desert rhubarb, typically can’t survive in such an arid climate.

But when the researchers measured the plant’s water absorption during a light rain, they discovered that water infiltrated the soil 10 times deeper around the desert rhubarb than in surrounding areas. Upon closer examination, scientists discovered deep grooves around the plant’s veins, which are coated in a waxy cuticle that helps channel water down to the root.

“Even in the slightest rains,” the researchers wrote, “the typical plant harvests more than 4,300 cubic centimeters of water per year and enjoys a water regime of about 427 millimeters per year, equivalent to the water supply in a Mediterranean climate.”

Some scientists say the desert rhubarb isn’t all that, however. “Many plants channel water to their base to be absorbed by the root,” Lindy Brigham, a plant ecologist from the University of Arizona, wrote in an email. “Just look at the way plant leaves are shaped and how they branch from the base in many cases.” The architecture of the desert rhubarb’s leaves is unusual, she said, but not necessarily the only example of this adaptation.

IISc to extract oil from Diatoms, algae

Driving will soon be a pollution-friendly activity if a small team of scientists from India and Canada have their way. Scientists at the Indian Institute of Science (IISc) have collaborated with their counterparts in Canada to ensure that global warming becomes a thing of the past.

According to the scientists, the answer to a clean and sustainable energy production lies in the microscopic algae — diatoms.

Some geologists believe that a majority of the world’s crude oil originated from diatoms. “Diatoms are the lowest in the order of the food chain, but are known to have oil glands that can yield an effective amount of oil. They also act as carbon sequesters trapping in carbon and releasing oxygen. We hope that this could work as a replacement for conventional energy or gasoline paving the way for a clean fuel that can effectively work as a solution to tackle global warming,” said Dr T.V. Ramachandra at IISc.

The research, that will soon be published in an international journal, indicates that a solution to the impending crude oil scarcity exists. It offers solutions for a cost-effective renewable source of alternative energy and also helps stop the emission of carbon dioxide into the atmosphere to an extent. Diatoms can trap and store carbon, sending out emissions free of any pollutants.

The team that comprises IISc professors Durga Madhab Mahapatra, Karthick B. and Dr Ramachandra and Richard Gordon from the University of Manitoba in Canada have also proposed a new approach to sustainable energy that uses solar panels by incorporating altered diatoms that secrete oil products.

Gene Protects Alcoholism

In an interesting finding, a study revealed that a gene variant detected among a tribe in Orissa has been protecting them from harmful effects of alcohol.

The study conducted by the department of anthropology at Utkal University here has showed that the Bondas — one the most primitive tribes of Orissa- are immune to the side effects of alcoholism.

Alcohol is an agent of cirrhosis of liver, toxic psychosis, gastritis, pancreatitis, cardiac myopathy and so on. But surprisingly none of these diseases are seen among the Bonda highlanders, who are addicted to different kinds alcoholic beverages.

The reason: presence of a gene variant ALDH2.

Jayant Kumar Nayak, a research scholar of Anthropological Survey of India, in association of with the Utkal University has conducted a study on Bondas to know whether they are genetically protected from alcoholism. On a proportionate random sampling, out of 25 villages, he selected nine for the study covering 714 households of 2,700 population. Genomic DNA was extracted from 110 unrelated adult Bondas by the ASI following ethical guidelines after taking their consents. Both ADH and ADLH2 genes, considered protecting variants for alcohol, were detected.

Curry leaves Fights Tooth Decay

The curry leaf tree (Murraya Koenigii spreng – a green leafy vegetable) is grown all over India and other countries for its aromatic leaves which are used daily as an ingredient in Indian cuisine.

The fresh curry leaves contain 2.6% volatile essential oils (containing sesquiterpenes and monoterpenes) and the essential oils in the curry leaves are sufficiently soluble in water.

They contain 21000mug total carotene, 7100mug beta carotene, 93.9mug total folic acid, 0.21mg riboflavin, 0.93mg iron, 830mg calcium, 57mg phosphorus and 0.20mg zinc per 100g.

The cold extract of curry leaves (10g of cut fresh curry leaves in 200ml of distilled water) has a pH of 6.3 to 6.4. (unpublished personal observations). Chlorophyll has been proposed as an anticariogenic agent and it also helps to reduce halitosis8.

We have observed that holding curry leaves in the mouth for 5 to 7 minutes is helpful in reducing halitosis and that the terpenes have been found to reduce airborne chemicals and bacteria.

In addition to the presence of EO, the curry leaves contain chlorophyll, beta carotene and folic acid, riboflavin, calcium and zinc and all these can act on the oral tissues and help in keeping up good oral health. Chewing 2 to 4 fresh curry leaves with 10 to 15mls water in the mouth, swishing for 5 to 7 minutes and rinsing the mouth out with water can be of help in keeping good oral hygiene and as the curry leaf is a green leafy vegetable it will be safe and cheap to use as mouthwash.

Eat Indian curry to lose weight














Eating lots of curry may help you lose weight, research suggests.

Scientists believe that haldi, or turmeric, which is used in most Indian meals, has an active ingredient that can help fight obesity.

A meal that includes haldi will lead to less weight gain than one without the yellow powder.

This is because haldi contains a plant-based chemical called curcumin which suppresses the growth of fat tissue in mice and human cell cultures, according to a study by Tufts University in Boston, published in the Journal of Nutrition.

Curcumin is also easily absorbed by the body, the researchers said, after experiments on mice.

"Weight gain is the result of the growth and expansion of fat tissue, which cannot happen unless new blood vessels form, a process known as angiogenesis," said senior study author Mohsen Meydani of the Jean Mayer U.S. Department of Agriculture Human Nutrition Research Center on Aging at Tufts.

"Based on our data, curcumin appears to suppress angiogenic activity in the fat tissue of mice fed high fat diets," he said in a statement.

In particular, turmeric is effective when added to a high-fat meal, suggesting it could help fight obesity.

Researchers gave one set of mice high-fat diets and another set the same food with 500mg of curcumin added to each meal.

After 12 weeks, the mice which were fed curcumin weighed less than those which did not eat it.

The next step will be to perform clinical trials on humans, said the researchers.

Soybeans Grow Where Nuclear Waste Glows


Photo: Soybeans growing near the Chernobyl nuclear reactor.

Soy crops are so tough they can flourish in the contaminated soil around Chernobyl and produce healthy offspring.

If scientists can understand how plants survive in ultra-hostile environments, it will help them engineer super hearty plants to withstand drought conditions or grow on marginal cropland.

“The fact that plants were able to adapt to the area of the world’s largest nuclear accident, is very encouraging,” says Martin Hajduch, a plant biotechnology expert at the Slovak Academy of Sciences and coauthor of the study in the Journal of Proteome Research. “So we were interested to know how plants can do such a job.”

Hajduch’s team built and harvested seeds from a garden near the village of Chistogalovka, which is roughly five kilometers from the ruined nuclear power plant. They analyzed the seeds with all sorts of modern proteomics tricks, going a step beyond the narrowly-focused studies that other scientists have done.

Biologists have been studying the effects of radiation on plants for decades, and they have identified a handful of proteins that seem to protect crops from genetic damage, but this is the first time that anyone has taken a snapshot of everything that’s going on inside of Chernobyl-grown vegetables.

The Slovak scientists started by freezing each seed with liquid nitrogen and crushing it to extract a mix of proteins. Then they sorted those molecules in an electrified block of gel, and identified each one with a mass spectrometer. As a reference, they did the same thing to seeds from a garden 100 kilometers from the disaster area.

Hajduch learned that the contaminated plants make a lot of changes to defend themselves, adjusting the levels of dozens of proteins that also guard against disease, heavy metals, and salt. All of that makes sense, but the biggest difference between plants from the wasteland and the controls was somewhat surprising. The levels of hundreds of proteins that are known for their ability to shuttle other proteins around — or lock them up in storage — had been lowered.

As a result of those adjustments, the levels of Cesium-137 in the beans was remarkably low. The plants are healthy and fertile, but definitely not safe to eat. Hajduch says that he will complete a study of their progeny soon, but he wouldn’t want to make them into tofu.

Biotech crops' global value reaches $7.5 billion

The global market value of biotechnology crops reached $7.5 billion in 2008, up from $6.9 billion in 2007.

Last year’s $7.5 billion represented 14 percent Dr. Clive James, founder and current board chairman of the International Service for the Acquisition of Agri-biotech Applications (ISAAA).

New York (USA)-based ISAAA is a not-for-profit organization with an international network of centers designed to contribute to the alleviation of hunger and poverty by sharing knowledge and crop biotechnology applications.

The network includes the Southeast Asia Center based in Los Baños, Laguna, headed by Dr. Randy Hautea, currently ISAAA global coordinator and former director of the University of the Philippines Los Baños-Institute of Plant Breeding (UPLB-IPB).

Dr. James’ report, titled “Global Status of Commercialized Biotech/GM Crops: 2008”, was presented by Dr. Hautea and former UP president Dr. Emil Q. Javier at a media forum last Feb. 12 at the Richmonde Hotel in Pasig City.

In his report, the Welsh-born research administrator projected that the global value of the biotech crop market for 2009 is approximately $8.3 billion.

Of the genetically modified (GM) crops produced in 2008, biotech maize constituted the biggest chunk of the global biotech market – $3.6 billion or 48 percent.

It was followed by soybean, $2.8 billion (37 percent); cotton, $0.9 billion (12 percent); and canola, $0.2 billion (three percent).

The other biotech crops raised in 2008 in 25 countries were papaya, squash, tomato, sweet pepper, alfalfa, poplar, petunia, carnation, and sugar beet.

Biotechnology boom raises security fears

As rapid advances in biotechnology make it easier to develop and produce deadly organisms, experts are calling for better industry oversight to stop that progress benefiting criminals and terrorists.

Hundreds of research laboratories are springing up around the world as costs and development times tumble and scientists compete to create products with commercial potential for medicine or food production.

In 2002 it took five years to develop the genomic sequence of a polio virus. Three years later it took a week for a team the same size to do the same on a virus of similar length.

Such rapid progress has left policymakers wondering how to ensure security in a disparate, thinly regulated industry -- a concern that surfaced at a weekend conference in Morocco where experts considered the threat of pandemics and major biological incidents in the Middle East and North Africa.

"There are so many advances in bacteriology and gene sequencing leading to the possibility of designing genes -- that is what is driving the concern," said Tim Trevan of the International Council for the Life Sciences (ICLS).

Organisms could be genetically manipulated to defeat vaccines, mild diseases could be turned into deadly ones and lethal viruses and bacteria might be created from scratch.

Equipment such as micro-reactors, flow reactors and disposable reactors to produce useable volumes of complex molecules were not even available 10 years ago.

"You want something very infectious if you aim to bring down society," said Trevan. "Whether you kill people or incapacitate them it doesn't really matter, as long as there is a major effect. This could all theoretically be engineered genetically."

A BIOTECH CHERNOBYL?

Potentially dangerous organisms tend to be harder to spot at the development stage than nuclear materials.

"You are talking about people and knowledge -- you're not going to just spring into a laboratory and find incriminating material," said ICLS President Terence Taylor.

He pointed to documents recovered from al Qaeda which had showed the group was considering developing biological weapons.

"If there is a serious, catastrophic incident involving the use of biotechnology, that will hold up the science like Chernobyl did with nuclear," said Taylor. "That's why we need to worry now."

Nuclear technology remains mostly in the hands of governments and heavily regulated state enterprises. In contrast, advanced biotechnology is already seeping into the consumer mainstream.

Taylor said parts of the private sector had taken a lead in building safeguards. One industry body, the International Association for Synthetic Biology, had developed software to allow its members to screen their customers.

Conference delegates called for better regulation and more cross-border collaboration to detect and ward off biological threats and share best practices.

Attacks involving anthrax-laced letters in the United States in 2001 killed five people, including two U.S. Postal Service workers from a facility in Washington, D.C., and made 13 sick. Thousands were given antibiotics to prevent disease.

In 1995, Japan's Aum Shinrikyo cult killed 12 people in a Sarin gas attack on Tokyo's subway system.

"The thinking is out there and it is naive to assume some people are not exploiting available technology," said Taylor.

India likely to launch bio-tech rice by 2011-12

Biotech rice is likely to be launched in India by 2011-12, after it gets all the required clearance, Sawapan Datta professor Calcutta University said today.

“After all the required processes and approvals, it is estimated that bio-tech enhanced rice could be launched in India by 2011-22,” Datta told reporters.

He said, with India’s population estimated to reach 1.3 billion by 2017, the government has estimated a 14 million tonnes shortage of the food grain.

Therefore, with low yield and rising demand it is essential to increase rice production, which is the second most consumed cereal grain, after maize, Datta said.

“Biotech enhanced rice could double farmer yields and can save traditional low yielding varieties from extinction by converting taller varieties into shorter heights with multiple tillers resulting in higher yields,” he said.

According to Central Rice Research Institute (CRRI), Cuttack, head plant improvement G J N Rao, “Bio-tech rice can enhance productivity and help protect the environment by reducing the use of chemical pesticides.”

CRRI is working on developing nutritionally enhanced rice for high protein and high-iron to help address the problem of malnutrition among women and children.

Biotech firm eyes algae as growth area

The simple marine organism that causes pond scum will someday be used to make people healthier.

A research team at Ocean Nutrition Canada Ltd. in Dartmouth has found algae along the coast of Nova Scotia capable of providing essential nutrients in quantities sufficient to support commercialization.

Chief executive officer Robert Orr said Friday the fish-oil manufacturer is keeping the lid on most details for competitive reasons.

"There is a lot of research underway in this field around the world. We’ve made significant progress here in Nova Scotia but haven’t been overly public about it," he said.

Ocean Nutrition is preparing a fish-powder plant worth an estimated $23 million in Burnside Park. It is expected to open in a few months, but production will be linked to the health of the food industry."We will see more new food products launched as the economy improves," said Mr. Orr.

When the plant opens, operations will focus on turning oil from anchovies and sardines into fish oil and an omega-3 powder to be used as nutritional supplements to food.

The capacity to produce nutrients would increase significantly if a micro-fermentation process could be used to culture algae.

"We would be going directly to the same algae consumed by the fish to obtain omega-3 fatty acids and other nutritional compounds," Mr. Orr said.

Omega-3 fatty acids from fish are linked to reduced risk of heart disease and improved brain function.

Extracting essential nutrients from fish like anchovies or sardines is a costly process, and the ability to use large volumes of marine algae as a raw product has huge implications for this emerging industry.

Mr. Orr said there is a large body of evidence supporting the health benefits of nutrients found in high proportions in fish, and North Americans eat very little fish, so the future of the industry looks good.

"Omega-3 is to the cells what calcium is to the bones," he said.

India fourth largest adopter of biotech crop in the world

India became the fourth largest adopter of biotech crop in the world, displacing Canada, in 2008 and planting Bt cotton on 7.6 million hectares (82% of the total cotton are in the country), according to the International Service for the Acquisition of Agri-biotech Applications (ISAAA). This was almost a million and half hectares over planted area in 2007 (6.2 m ha, equivalent to 66% of the total cotton area in the country).A record five million small and resource-poor farmers planted Bt cotton in 2008, significantly up from only 3.8 m farmers in 2007, the ISAAA said.

Worldwide, by the end of the second decade of commercialization in 2015, ISAAA predicts that four billion accumulated acres of biotech crops would have been planted. Further, 200 million hectares of biotech crops annually will be planted in a total of 40 countries. In 2008, three new countries and 1.3 million new farmers adopted biotech crops and planted an additional 10.7 m ha, the Association, which has been tracking global biotech crop adoption trends since 1996, said.

Last year, 13.3 million farmers in 25 countries planted 125 million ha of biote4ch crops, leading to the sixth largest growth spurt in 13 years of reporting . Infact, the two billionth cumulative acre of biotech crops was also planted in 2008, just three years after the first billionth acre was planted. That milestone, though, took a whole decade to be reached.

Cotton area in India comprises about 21% of the total are in the world and roughly 13% of the total cotton output in the world. At the national level, cotton production increased from 15.8 million bales in 2001-02 to 32.2 million bales in 2008-09, more than doubling cotton production in the short span of seven years. The ISAAA’s annual brief on Global Status of Commercialised Biotech/GM Crops 2008 maintained that for the seven year period 2002-08, there was a 150-fold increase in Bt cotton in India.

That is four times the 74-fld increase for global biotech crops during the 13 period from 1996-2008.Accordign to the report, averge cotton yields following adoption of biotech increased from only 308 kg/ha in 2002 to 591 kg/ha in 2008, registering a 50% increase in yield. In tandem, cotton exports increased from 0.05 million bales in 2001-02 to an estimated 8.5 million bales in 2007-08. Also, the number of biotech events increased from one Event in 2002 to 4 Events in 2007 and t o five Events in 2008. There were 274 location-specific Bt cotton hybrids in 2008 compared to only 131 in 2007 and only three in 2002. Accordign to the ISAAA brief, there has been substantial increase in the approval of double genes Bt cotton hybrids to delay insect-pest resistance. From only 21 BG II hybrids in 2007, the number went up to 94 BG II hybrids in 2008.

“In India, growers increased income by upt to $250 (Rs 10,000) or more per hectare, increasing farmer incomes nationally by $3.2 billion in the period 2002 to 2007 and $2 billion in 2007 alone,” the ISAAA brief has claimed. Adding to the increasing adoption of biotech crop was the apex court’s decision in 2008 to lift restrictions on all field trials and commercial releases such crops. During the year, India also drafted a plan to establish a National Biotechnology Regulatory Authority (NBRA) and adopted a new set of guidelines for GE (genetically engineered) plants and foods, even as the GEAC or the Genetic Engineering Approval Committee commercially released publicly bred Bt cotton varieties. India deregulated approved GM cottone Evetns and joined the OECD seed certification schemes.

Significantly, it was also the year when Mahyco received experimental seed production approval for its Bt Brinjal hybrids. For all that it was one of the leading, and earliest, developing countries to adopt biotech crops, India has yet to approve commercialsiation of any biotech food crop although Bt soyabean and Bt Maize are being cultivated by other countries for a decade or more now. In the face of criticism on the safety aspects of biotech crop in the country, commercial biotech crops have so far attracted less hue and cry in the second, and food safety centric, decade of worldwide GM (genetically modified) crop adoption. Biotechnology research in food crops in the country, however, are on for a wide variety of food crops such as banana, cabbage, acstor, cauliflower, corn, gorundnut, mustard, okra, onion, papaya, potato, rice and tomato.


“Future growth prospects for biotech crops are encouraging,” chairman and founder of ISAAA and author of the report Clive James said here, adding “The positive experiences int ehse new regional footholds in the south, north and west Africa will help lead the way for neighbouring countries to learn by example. Additionally, political leaders globally are increasingly viewing biotech enhanced crops as a key part of the solution to critical social issues of food security and sustainability.”

Africa is considered the “final frontier” for biotech crops as it has perhaps the greatest need for increased crop output and the most number of people to gain from it. Biotech famrming began in the African nations of Egypt and Burkina Faso in 2008, when Egypt planted 700 ha of Bt Maize and Burkina Faos planted 8500 ha of Bt cotton, joining S Africa, which since 1998 has adopted cotton, maize and soyabean biotech crops.

James said that increased political support from key regions such as the G-8 leadership (for the first time) to biotech crop, the EU and China had strengthened the acceptance of such crops in countries worldwide. “Biotech crops make two important contributions to global food security. First, they increase yields, which increase food avalabilityand supply. Second, they reduce production costs, which will also ultimately help reduce food prices. With 9.2 billion people to be fed by 2050, biotechnology plays a crucial role in helping to satistfy the growing demand.” As part of that goal, biotech is beginning to identify solutions to the growing challenges with drought being seen in sub Saharan Africa and Latin America, he said. Drought is the single largest constraint to increased productivity. For example, Argentina now faces a drought so severe that farmers have made a oss on their wheat crop. Drought-tolerant crops, maize in particular, are an emerging reality with seeds exp ected to be commercialized in the USA by 2012 or sooner and in Africa, by 2017, the ISAAA founder-chairman said.

A new biotech crop, RR sugar beet, was first commercialised in the USA and Canada in 2008.

Biotech excited about hair-growth results

If your forehead is more like a fivehead, or you've started to see a lot more scalp at the crown of your head, the tiny San Diego biotechnology company Histogen has some promising news.

The company today is unveiling preliminary results from an early-stage clinical trial that showed its experimental hair regrowth therapy, ReGenica, increased new hair growth and the thickness of existing hair in men after 12 weeks.

“These results appear to be phenomenal, although this trial is still in the very early stages,” said Los Angeles-based hair transplant specialist Dr. Craig Ziering.

“Wimpy hairs became thicker, which is pretty significant to the patient because even if you cannot increase the numbers of hairs, if you increase the diameter, you increase the volume. And preliminary hair counts show there was an increase in new hair of 15 to 20 percent in some patients,” said Ziering, a paid member of the company's scientific advisory board.

ReGenica is made of a cocktail of proteins that are present in the early-stage embryo and help direct stem cells to become either hair, bone or blood, said Histogen Chief Executive Gail Naughton.

Although scientists have known about the role these proteins play, Histogen's aha moment was figuring out how to create them in a lab, said Naughton, who is also dean of San Diego State University's School of Business Administration.

Fibroblasts, early-stage stem cells that form connective tissue, are grown in the simulated low-oxygen and free-floating, low-gravity conditions of the embryo, Naughton said. The important Wnt proteins and growth factors then build up in that environment, she said.

The 18-person company, which opened in 2007, conducted research showing ReGenica stimulated hair growth in animals. It started its Phase 1 human trial to show the therapy was safe; no dangerous side effects were experienced, Ziering said.

Histogen was also hoping the trial would show ReGenica's effectiveness, which might give the company the buzz it needs to raise funding, build a manufacturing facility and then begin Phase 2 trials, Naughton said.

The Phase 1 trial involves 25 men ages 18 to 45 who have varying stages of male-pattern baldness.

Each of the balding spots was mapped into quadrants. Each quadrant received an injection of either the drug or a placebo. Some of the quadrants were also treated with microdermabrasion or lasers as well as the drug, to test previous medical theory that a wound helps to stimulate stem cells in the skin to regenerate hair follicles.

At 12 weeks, penny-size pieces of scalp were biopsied to observe the changes. Histogen staff even counted the follicles and hairs sprouting out of them. Once the trial is completed, an independent data-monitoring board will review the results after five months and make an assessment.

More than 50 million men in the United States alone suffer from hair loss, and about 35 million women are dealing with the problem, said Ziering, who has been treating patients for hair loss for 18 years.

“There's a tremendous need for something that can help people with their hair loss because there are many ramifications on people's lives,” Ziering said.

Histogen's product shows promise to do multiple things, including slowing the progressive nature of hair loss, increasing the thickness of the follicles and actually getting new follicles to grow, the physician said.

Histogen also sees ReGenica as a means toward lifesaving therapies that trigger stem cells to generate new tissue in damaged heart muscle and new neurons in damaged spinal cords, Naughton said.

“We wanted to go after a market where there is really an unmet need and a large patient population, which could help us generate the cash flow to fund longer-term projects that would be more of a regulatory and reimbursement hurdle,” she said.

Biotech rice may be in the market by 2010

BIOTECH ricethe insect resistant variety and Golden Rice—will lead the new genetically modified crops for commercial use in the second wave (2006 to 2015) of market availability, according to the International Service for the Acquisition of Agribiotech Applications (ISAAA).

Dr. Randy Hautea, ISAAA global coordinator and its SEAsiaCenter director, told reporters that Bacillus thuringiensis (Bt)-resistant rice from China “may be available within 24 months,” or between now and 2010, and Golden Rice by 2012.

Hautea made the disclosure last week at the press conference on the global launching of the 2008 Global Status of Commercialized Biotech/GM (Genetically Modified) Crops report authored by Dr. Clive James, founder and chairman of ISAAA board of directors.

Bt rice is “extensively field tested in China and awaiting approval by the Chinese regulatory authorities” for commercialization, the report said.

Golden Rice—or genetically biofortified rice with beta carotene that produces vitamin A—is being field-tested at the International Rice Research Institute in Los Baños, Laguna. Its adoption for the Philippines is being done by the Philippine Rice Research Institute with two other traits incorporated in the rice—tungro virus and bacterial blight resistance.

The ISAAA report recognized biotech rice as “the most important of the new biotech crops that are now ready for adoption.”

This development is of great significance because rice is the most important food crop in the world, especially for the poor, aside from answering the current food security problem, James said.

“[More than] 90 percent of rice is grown and consumed in Asia by some of the poorest people in the world—the 250-million Asian households whose resource-poor rice farmers cultivate on average a meager half a hectare of rice,” the ISAAA report said.

Bt eggplant may be available as the first biotech-food crop in India within the next 12 months, the ISAAA report said. India is the fourth-largest producer of biotech crops with GM cotton planted in 7.6 million hectares.

Other crops that are expected to be available in the market before 2015 are potatoes with pest and/or disease resistance and modified quality for industrial use; sugar cane with quality and agronomic traits; and disease-resistant bananas.

Biotech vegetable crops—such as tomato, broccoli, cabbage and okra—that would require reduced amount of insecticides are being developed, along with propoor biotech cassava, sweet potato, pulses and ground nut, the report said.

Hautea noted the significance of 2015 as the end of the second decade when new biotech crops are available, because it is the target year under the Millennium Development Goals when a secure supply of affordable food is ensured and poverty and hunger have been reduced by 50 percent.

James said in the report that 2 billion acres or 800 million hectares were planted to biotech crops from 1996 to 2008, and that 13.3-million farmers in 25 countries planted biotech crops in 125 million hectares last year.

Among the notable developments, the report said, was the adoption of biotech crops in the African countries of Egypt (700 hectares of Bt corn) and Burkina Faso (8,500 hectares of Bt cotton), joining South Africa in biotech farming which, since 1998, has planted biotech cotton, corn and soybean.

“...Africa is considered the ‘final frontier’ for biotech crops as it has perhaps the greatest need and most to gain,” ISAAA said.

In the Philippines, 200,000 small farmers planted about 350,000 hectares of Bt corn farms in 2008.

A socioeconomic impact study cited by ISAAA said that small farmers in the Philippines earn an additional income of P7,482 a hectare in the dry season and P7,080 in the wet season from Bt corn in crop year 2003-2004.

Multiawarded biotech corn farmer Lydia Lapastora of Isabela province said in the same media briefing she netted P11,021 a hectare from planting GM corn compared with the traditional varieties.

Bt corn is the only transgenic crop commercially planted in the Philippines. However, 46 other products with GM traits, such as soya and canola, are allowed to be imported into the country, said Dr. Emil Javier, president of the National Academy of Science and Technology, in the same briefing.

Javier said in a speech that in order for the Philippines to hasten the development of biotech crops, it should “sharpen [its] focus” on transgenic traits already commercialized by other countries and apply them in local crops so that it could “reap the full benefits of plant biotechnology with the resources and opportunities at hand.”

He cited as example the development of Bt eggplant, and ring-spot virus-resistant papaya and delayed-ripening papaya in the country.

“We must put in more resources and speed up and scale up their testing and commercialization,” he urged.

He also raised the need for more lawyers and technical people with “business savvy” that would sort out the legal and financial applications of biotech technologies that could be applied in the country.

He said almost all of the country’s agribiotech research and development experts are in public hands but they do not have this kind of expertise in house.

“We must explore new ways of sourcing these expertise from the private sector to free our scientists from these roles they have no aptitude for, in the first place. We need lawyers and ‘techies’ to negotiate with foreign technology owners as well as with domestic private investors who will put up the capital and manage the enterprise,” Javier said.

Besides the 25 countries growing biotech crops, Hautea said, 30 countries are not growing but importing such products, and three to four countries “unofficially” (not legally sanctioned by their governments) grow GM crops.

The countries planting biotech crops are (according to hectarage): United States covering 62.5 million hectares with soybean, corn, cotton, canola, squash, papaya, alfalfa and sugar beet; Argentina, 21 million (soybean, corn and cotton); Brazil, 15.8 million (soybean, corn and cotton); India, 7.6 million (cotton); Canada, 7.6 million (canola, corn, soybean and sugar beet); China, 3.8 million (cotton, tomato, poplar, petunia, papaya and sweet pepper); Paraguay, 2.7 million (soybean); South Africa, 1.8 million (corn, soybean and cotton); Uruguay, 700,000 (soybean and corn); Bolivia, 600,000 (soybean); Philippines, 400,000 (corn); Australia, 200,000 (cotton, canola and carnation); Mexico, 100,000 (cotton, soybean); Spain, 100,000 (corn);

Those planting biotech crops in less than 100,000 hectares are Chile with corn, soybean and canola; Colombia (cotton and carnation); Honduras (corn); Burkina Faso (cotton); and Czech Republic, Romania, Portugal, Germany, Poland, Slovakia and Egypt with GM corn.

By 2015, the ISAAA projection is that from the current 25 countries 40 more will plant biotech crops with 20 million or more farmers involved in about 200 million hectares.
