Retracing early cultivation steps: Lessons from comparing citrus genomes
Citrus is the world's most widely cultivated fruit crop but it is now under attack from citrus greening, an insidious emerging infectious disease destroying entire orchards.

Common bean genome sequence provides powerful tools to improve critical food crop
An international collaboration of researchers, led by Jeremy Schmutz of the HudsonAlpha Institute for Biotechnology and Phillip McClean, of North Dakota State University have sequenced and analyzed the genome of the common bean to begin to identify genes involved in critical traits such as size, flavor, disease resistance and drought tolerance.

No limits to human effects on clouds
Weizmann Institute research shows how atmospheric particles affect cloud formation in real time.

New molecule enables quick drug monitoring
Scientists at EPFL have invented a molecule that can easily and quickly show how much drug is in a patient's system.

A tiny molecule may help battle depression
Levels of a small molecule found only in humans and in other primates are lower in the brains of depressed individuals, according to researchers at McGill University and the Douglas Institute.

More than just a hill of beans: Phaseolus genome lends insights into nitrogen fixation
The US Department of Energy Office of Science has targeted research into the common bean because of its importance in enhancing nitrogen use efficiency for bioenergy crops sustainability, and for increasing plant resilience and productivity in the face of the changing climate and environment.

Health Affairs asks: Where can we find savings in health care?
The June issue of Health Affairs features various approaches to cost savings in the US health care system, and several other articles that may be of interest to the global community.

Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fueling further climate change, a study suggests.

Targeting tumors using silver nanoparticles
Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique -- and important -- properties.

Sequencing of citrus genomes points to need for more genetic diversity to fight disease
Sequencing the genomes of domesticated citrus revealed a very limited genetic diversity that could threaten the crop's survival prospects, according to an international research team.

Quick getaway: How flies escape looming predators
When a fruit fly detects an approaching predator, the fly can launch itself into the air and soar gracefully to safety in a fraction of a second.

Longer telomeres linked to risk of brain cancer
New genomic research led by UC San Francisco scientists reveals that two common gene variants that lead to longer telomeres, the caps on chromosome ends thought by many scientists to confer health by protecting cells from aging, also significantly increase the risk of developing the deadly brain cancers known as gliomas.

Study reveals rats show regret, a cognitive behavior once thought to be uniquely human
New research from the Department of Neuroscience at the University of Minnesota reveals that rats show regret, a cognitive behavior once thought to be uniquely and fundamentally human.
