A radical plan to curb global warming and so reverse the climate change caused by our rampant burning of fossil fuels since the industrial revolution would involve covering parts of the world`s deserts with reflective sheeting, according to researchers writing in the International Journal of Global Environmental Issues.

Researchers at The Scripps Research Institute have solved one of biology`s neatest little tricks: they have discovered how a cell`s outer membrane pinches a little pouch from itself to bring molecules outside the cell inside—without making holes that leak fluid from either side of the membrane.
In the cover story of the December 26 issue of [...]

One of the most promising new ideas about the causes of cancer, known as the cancer stem-cell model, must be reassessed because it is based largely on evidence from a laboratory test that is surprisingly flawed when applied to some cancers, University of Michigan researchers have concluded.
By upgrading the lab test, the U-M scientists showed [...]

Scientists have shown that tiny crystals found inside bacteria provide a magnetic compass to help them navigate through sediment to find the best food.
Researchers say their study could provide fresh clues to explain biomagnetism – a phenomenon in which some birds, insects and marine life navigate using the magnetic field that encompasses the Earth.
The study [...]

Scientists have discovered where they believe would be the best place to find ice on the moon. Astrophysicists, led by an expert at Durham University, say if frozen water exists then it is most likely to be found near to the moon’s poles in craters that are permanently shaded from the sun.
Their findings are based [...]

The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement.
In recent years, there has been growing evidence for the hypothesis that the effect of [...]

A team led by International Arctic Research Center scientist Igor Semiletov has found data to suggest that the carbon pool beneath the Arctic Ocean is leaking.
The results of more than 1,000 measurements of dissolved methane in the surface water from the East Siberian Arctic Shelf this summer as part of the International Siberian Shelf Study [...]

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.
While the anatomic location in the embryo where blood stem cells originate has been well documented, the cell type from which they spring was less understood. [...]

A team of scientists from across Europe are embarking on new research to develop a treatment for food allergy.
"Food allergy affects around 10 million EU citizens and there is no cure," says Dr Clare Mills of the Institute of Food Research, a lead partner in the Food Allergy Specific Therapy (FAST) research project. "All people [...]
