Stem cell technique helps women grow their own implants

Daily Mail - Women have grown their own breast implants through pioneering stem cell treatment, it emerged yesterday. Scientists harvested the stem cells from the women's own fat and encouraged them to form breast tissue...

Global-warming skeptics cite being 'treated like a pariah'

There's science in love, you know, and that means there's science in Valentine's Day. Science on Valentine's Day is like cold fusion instead of ethanol. Completely wonderful. And we have it all right here.

Not sure who to date? Garth Sundem answers it in The Valentine's Day Man-O-Meter. Be sure to take it as gospel because he never just makes stuff up.

VK Raina, leading glaciologist and former ADG of the Geological Society of India, told the Hindustan Times that out of 9,575 glaciers in India, till date, research has been conducted only on about 50. Nearly 200 years data has shown that nothing abnormal has occurred in any of these glaciers.

It is simple. The issue of glacial retreat is being sensationalised by a few individuals, the septuagenarian Raina claimed.

New research challenges traditional perceptions of contemporary climate as sole determiner of richness of species.

The climate is changing! But how does that affect nature? New research challenges traditional perceptions of contemporary climate as sole determiner of richness of species.

An international research team led by Professor Carsten Rahbek from Department of Biology, University of Copenhagen, questions traditional beliefs that contemporary climate alone determines richness of species, that is, how life is distributed on earth. The current issue of Science magazine highlights the research in Editor’s choice.

An artificial nose could be a real benefit at times: this kind of biosensor could sniff out poisons, explosives or drugs, for instance. Researchers at the Max Planck Institute for Polymer Research and the Max Planck Institute of Biochemistry recently revealed a technique for integrating membrane proteins into artificial structures.

Membrane proteins have several important functions in the cell, one of which is to act as receptors, passing on signals from molecules in the air, for example, to the cell interior. They are thus ideal biosensors, but until now were difficult to access in the lab.

When man made his way out of Africa some 60,000 years ago to populate the world, he was not alone: He was accompanied by the bacterium Helicobacter pylori, which causes gastritis in many people today. Together, man and the bacterium spread throughout the entire world. This is the conclusion reached by an international team of scientists led by Mark Achtman from the Max Planck Institute for Infection Biology in Berlin, Germany. The researchers also discovered that differences developed in the genetic makeup of the bacteria populations, just as it did in that of the various peoples of the world.
