'Wildly heterogeneous genes'
Cancer tumors almost never share the exact same genetic mutations, a fact that has confounded scientific efforts to better categorize cancer types and develop more targeted, effective treatments.

Tropical forest carbon absorption may hinge on an odd couple
A Princeton University-based study found that a unique housing arrangement between trees in the legume family and the carbo-loading rhizobia bacteria may determine how well tropical forests can absorb carbon dioxide from the atmosphere.

Scientists discover cosmic factory for making building blocks of life
Scientists have discovered a

Approved cancer drug potentially could help treat diabetes, Stanford researchers find
A pair of studies by researchers at the Stanford University School of Medicine has identified a molecular pathway -- a series of interaction among proteins -- involved in the development of diabetes.

Researchers discover evidence to support controversial theory of 'buckyball' formation
Researchers report the first experimental evidence that supports the theory that a soccer ball-shaped nanoparticle commonly called a buckyball is the result of a breakdown of larger structures rather than being built atom-by-atom from ground up.

Superconductivity to meet humanity's greatest challenges
The stage is now set for superconductivity to branch out and meet some of the biggest challenges facing humanity today.

Several common differentially expressed genes between Kashin-Beck disease and Keshan disease
Kashin-Beck disease and Keshan disease are mainly endemic to China.

Achilles' heel of ice shelves is beneath the water, scientists reveal
New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 percent of ice loss in some areas.

Tropical forests 'fix' themselves
Tropical forests speed their own recovery, capturing nitrogen and carbon faster after being logged or cleared for agriculture.

White blood cell levels tied to meal time
A new link between meal times and daily changes in the immune system has been identified by UC San Francisco researchers, and has led them to question assumptions about the roles of specific immune cells in infection and allergy.

Report: Climate change to shift Kenya's breadbaskets
Kenyan farmers and agriculture officials need to prepare for a possible geographic shift in maize production as climate change threatens to make some areas of the country much less productive for cultivation while simultaneously making others more maize-friendly, according to a new report prepared by the International Food Policy Research Institute and the Association for Strengthening Agricultural Research in Eastern and Central Africa.

Functional genetic variation in humans: Comprehensive map published
European scientists, led by researchers from the University of Geneva's Faculty of Medicine in the context of the GEUVADIS project, today present a map that points to the genetic causes of differences between people.

Quantum entanglement only dependent upon area
Two researchers at UCL Computer Science and the University of Gdansk present a new method for determining the amount of entanglement -- a quantum phenomenon connecting two remote partners, and crucial for quantum technology -- within part of a one-dimensional quantum system.
