Polar bears evolved as a separate species far earlier than previously thought, according to a new genetic study, which adds to worries about their ability to adapt in a rapidly warming world.
A University of Colorado Boulder-led team has developed a new monitoring system to analyze and compare emissions from man-made fossil fuels and trace gases in the atmosphere, a technique that likely could be used to monitor the effectiveness of measures regulating greenhouse gases.
Stressed out lizard moms tend to give their developing embryos short shrift, but the hardship may ultimately be a good thing for the babies once they're born, according to a study published in the journal Physiological and Biochemical Zoology.

Scientists have discovered proof that the evolution of intelligence and larger brain sizes can be driven by cooperation and teamwork, shedding new light on the origins of what it means to be human. The study appears online in the journal Proceedings of the Royal Society B and was led by scientists a...
New research findings show how it may be possible to render cancer tumours harmless without affecting the other cells and tissues in the body. The findings apply to cancers including breast, lung and bowel cancer. The study was carried out at Lund University in Sweden.
To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested - and demonstrated - a counterintuitive concept: solar cells should be designed to be more like LEDs, able t...
Global thought leaders devoted to the latest developments in human, plant and animal genome sciences will gather at ICG Americas 2012 in Philadelphia September 27-28.
