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.

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.

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.

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.
