Water 'thermostat' could help engineer drought-resistant crops
A gene that could help engineer drought-resistant crops has been identified by researchers. The gene, called OSCA1, encodes a protein in the cell membrane of plants that senses changes in water availability and adjusts the plant's water conservation machinery accordingly. The findings could make it easier to feed the world's growing population in the face of climate change.

Encyclopedia of how genomes function gets much bigger
A big step in understanding the mysteries of the human genome has been unveiled in the form of three analyses that provide the most detailed comparison yet of how the genomes of the fruit fly, roundworm, and human function. The analyses will likely offer insights into how the information in the human genome regulates development, and how it is responsible for diseases.

Dosage of HIV drug may be ineffective for half of African-Americans
Many African-Americans may not be getting effective doses of the HIV drug maraviroc because they are more likely than European-Americans to inherit functional copies of a protein that speeds the removal of the drug from the body.

Shared biology in human, fly and worm genomes: Powerful commonalities in biological activity, regulation
Researchers analyzing human, fly, and worm genomes have found that these species have a number of key genomic processes in common, reflecting their shared ancestry. The findings offer insights into embryonic development, gene regulation and other biological processes vital to understanding human biology and disease.

Why Listeria bacterium is so hard to fight
The harmful and potentially deadly bacterium Listeria is extremely good at adapting to changes. Now research uncovers exactly how cunning Listeria is and why it is so hard to fight. The discovery can help develop more efficient ways to combat the bacteria.

Attacking a rare disease at its source with gene therapy
The two main treatments for MPS I are bone marrow transplantation and intravenous enzyme replacement therapy, but these are only marginally effective or clinically impractical, especially when the disease strikes the central nervous system. Using an animal model, a team has proven the efficacy of a more elegant way to restore aberrant protein levels in the body through direct gene transfer.

RNA sequence could help doctors to tailor unique prostate cancer treatment programs
Sequencing RNA, not just DNA, could help doctors predict how prostate cancer tumors will respond to treatment, according to research. Because a tumor's RNA shows the real time changes a treatment is causing, the authors think this could be a useful tool to aid diagnosis and predict which treatment will most benefit individual cancer patients.

Boron facilitates stem cell growth, development in corn
The eastern half of the United States is plagued by boron deficient soil and corn and soybean farmers are required to supplement their soil with boron; however, little is known about the ways in which corn plants utilize the essential nutrient. Now, researchers have found that boron plays an integral role in development and reproduction in corn plants. Understanding how corn uses the nutrient can help farmers improve crop yields.

Protein's ability to inhibit HIV release discovered
A family of proteins that promotes virus entry into cells also has the ability to block the release of HIV and other viruses, researchers have found. The scientists performed a series of experiments that revealed the protein's ability to inhibit HIV-1 release, resulting in diminished viral production and replication.

Navigation system used by cancer, nerve cells, uncovered by scientists
A study in C. elegans worms identifies a 'roving detection system' on the surface of worm cells that may point to new ways of treating diseases like cancer, Parkinson's disease and amyotrophic lateral sclerosis. The study sheds light on the molecular mechanisms that enable both normal and cancerous cells to break through normal tissue boundaries and burrow into other tissues and organs.
