"Yeti Crab" Discovered in Deep Pacific

ts silky white looks may make it seem more at home in the Himalaya, but this unique creature was recently discovered in the deep darkness of the South Pacific.

Scientists found the small, blind crustacean last March during a deep-sea expedition some 900 miles (1,500 kilometers) south of Easter Island, which lies off the coast of Chile.
Divers using submersible vehicles were about a mile and a half (more than two and a quarter kilometers) below the surface when they spotted the animal near hydrothermal vents.

The creature, dubbed the "yeti crab," is so unusual that a whole new family of animal had to be created to classify it. Its official name is Kiwa hirsuta, and even after a year of study scientists say there's still much about it they don't understand.

The Sahara's largest crater discovered in Egypt

Two Egyptian researchers have discovered the remnants of the largest crater of the Sahara desert, which may have been formed by a meteorite impact tens of millions of years ago. The double-ringed crater of a 31 kilometre diameter is located in south-eastern Egypt, close to the Libyan border, and was found on satellite images.

The discovery was made by researchers at the Boston University in the US earlier this month. Dr Farouk El-Baz spotted the enormous crater while studying satellite images of the Western Desert of Egypt with his colleague, Dr Eman Ghoneim, at the university's Centre for Remote Sensing.

The double-ringed crater - which has an outer rim surrounding an inner ring - is approximately 31 kilometres in diameter. Prior to the latest finding, the Sahara's biggest known crater, in Chad, measured just over 12 kilometres. According to Dr El-Baz, the Centre's director, the crater's vast area suggests the location may have been hit by a meteorite that was more than one kilometre is diameter.

Sunglass, protect your eyes

As you know, UV ray is a risk factor for cataracts and macular degeneration, which also cause snow blindness and damage to the cornea and retina. The best defense is to choosing a good pair of sunglasses. Whether it's the height of summer or the depths of winter, good sunglasses are a necessity. And sunglasses are extra important if you're sensitive to light, whether from a corneal problem, or from certain drugs, such as antihistamines. Many people may wonder what is considering “ good”?

Now, let’s select the right one!

Mum's exercise boosts baby's brain - Jogging promotes boom of neurons in mouse brain.

Pregnant mice who take daily runs boost the production of new brain cells in their babies; but investigators say it is premature to say whether the same could be true in humans.

Researchers already knew that exercise in adult animals can bump up the production of new neurons in a region of the brain called the hippocampus, which is involved in learning and memory. But now it seems that the effect can be passed from mother to offspring.

The team gave one group of pregnant mice a running wheel and kept another group without. Given the chance, the animals ran about two to three kilometres per night, although they cut back as their pregnancy progressed.

To track brain growth, the researchers injected pregnant mice with a dye that marked out newly formed neurons in their infants. They injected other babies with the dye directly, after they were born.

During pregnancy, exercise seemed to dampen the growth of neurons in the developing embryos; babies in the wombs of exercising mothers had roughly 20% fewer neurons three-quarters of the way through pregnancy. But by the time mice were five weeks old, the situation looked quite different. The offspring of exercising mums were forming more neurons, and their hippocampus contained around 40% more of these cells in total.

UN pleads for food as drought grips Kenya

The United Nations food agency will run out of the supplies it needs to keep 3.5 million drought-stricken Kenyans alive because it has received just over a tenth of the required funding, officials said yesterday.

The situation in El Wak and other parts of Kenya was 'as bad as it gets', said James Morris, executive director of the World Food Programme. 'There is just no alternative if lives are going to be saved - the world has to provide food,' he said.

Dozens of people are reported to have died from hunger, and chronic malnutrition is widespread in north-eastern and eastern Kenya, but the government has not given any figures, even though it has declared the situation a famine.

The drought has turned a swathe of eastern Africa into a dustbowl and left almost 12 million people dependent on aid, the UN said. Kenyan President Mwai Kibaki has declared a national emergency and appealed for foreign assistance.
