New volcano island getting big in Japan

New volcano island getting big in Japan

Famously crowded Japan is getting a bit more space as a newly-formed volcanic island just keeps on growing. New footage of the remote Nishinoshima, some 1,000 kilometres south of Tokyo, shows a volcano erupting up to six times a minute, spewing huge volumes of magma -- and scientists say there is plenty more still...

New AIDS drug shields monkeys: Study

New AIDS drug shields monkeys: Study

Scientists said Wednesday a new drug tested on monkeys provided an astonishingly effective shield against an animal version of the AIDS virus, a major gain in the quest for an HIV vaccine. Macaque monkeys given the drug were able to fend off high repeated doses of the simian version of the human immunodeficiency virus...

Mysterious plumes on Mars stump scientists

Mysterious plumes on Mars stump scientists

A mystery is brewing on Mars: Amateur astronomers spotted enormous plumes erupting off the Red Planet's surface, leaving scientists puzzled, reports Space.com. More than 155 miles (250 kilometers) high and hundreds of miles across, the baffling plumes were spotted by amateur astronomers in the spring of 2012. The plumes reflect sunlight, which means they could be made of water ice, carbon dioxide ice or dust. But clouds made of those materials would be hard to explain with current models of the Martian atmosphere, Space.com says quoting scientists. Images of Mars from the last 20 years reveal that shorter plumes, reaching heights of about 62 miles (100 km), occasionally flare up from...

Penguins lost ability to taste fish: study

Penguins lost ability to taste fish: study

Penguins can taste only sour and salty food, scientists have discovered. A genetic study suggests the flightless birds lost three of the five basic tastes long ago in evolution. Taste is critical for survival in most animals, but may not matter in the penguin, which swallows fish whole, say researchers in China and the US. Many...

Heart of Earth's inner core revealed

Heart of Earth's inner core revealed

Scientists say they have gained new insight into what lies at the very centre of the Earth. Research from China and the US suggests that the innermost core of our planet has another, distinct region at its centre. The team believes that the structure of the iron crystals there are different from those found in...

Why cats like to sleep in cardboard boxes

Why cats like to sleep in cardboard boxes

Scientists may have cracked the answer to one of the great mysteries of the animal kingdom: why do cats sleep in cardboard boxes? Anyone who lived with a cat has probably come home to find his or her feline companion sleeping in a strange place. Carelessly discarded cardboard boxes are as good as any. According...

Ebola virus mutating, scientists say

Ebola virus mutating, scientists say

Scientists tracking the Ebola outbreak in Guinea say the virus has mutated. Researchers at the Institut Pasteur in France, which first identified the outbreak last March, are investigating whether it could have become more contagious. More than 22,000 people have been infected with Ebola and 8,795 have died in Guinea, Sierra Leone and Liberia. Scientists are...

Lost Beagle2 probe found 'intact' on Mars

Lost Beagle2 probe found 'intact' on Mars

The missing Mars robot Beagle2 has been found on the surface of the Red Planet, apparently intact. High-resolution images taken from orbit have identified its landing location, and it looks to be in one piece. The UK-led probe tried to make a soft touchdown on the dusty world on Christmas Day, 2003, using parachutes and...

Scientists make 'feel full' chemical

Scientists make 'feel full' chemical

Scientists have created a chemical that can be added to food to make people feel full. Initial tests showed it helped people to eat less and slow weight gain. It harnessed the power of a proprionate, which naturally makes us feel full when it is produced by breaking down fibre in the gut. Writing in the...

Mars rover finds stronger potential for life

Mars rover finds stronger potential for life

For lifeless chemical compounds to organise themselves into something alive, scientists generally agree, three sets of things must be present: Standing water and an energy source. Five basic elements: carbon, oxygen, hydrogen, phosphorus and nitrogen. And time, lots of time. In its search for environments where life might have started on Mars, the Curiosity rover has found...
