Griffith University tackles deadly Hendra virus
Australian medical researchers are on the brink of an effective human treatment for the deadly Hendra virus, and potentially the closely related Nipah virus, which has killed more than 200 people in South East Asia.

Latest genomic studies shed new light on maize diversity and evolution
BGI, the world's largest genomics organization, together with other 17 international institutes, announced that they completed the second generation of maize HapMap and genomics studies on maize domestication and improvement.

Intermittent hormone therapy for prostate cancer inferior to continuous therapy
An international randomized study finds intermittent androgen-deprivation therapy has some quality-of-life benefits, but overall survival times don't measure up to those seen with continuous therapy.

Bug-bomb foggers are no match for bed bugs
Recent research published in the Journal of Economic Entomology shows

Lower income cancer patients less likely to be involved in clinical trials
A large SWOG survey finds patients with lower income less likely to participate in a clinical trial and more likely to be concerned about how to pay for clinical trial participation.

Nuclear and coal-fired electrical plants vulnerable to climate change
European and US scientists project that thermoelectric power generating capacity -- which supplies the vast majority of the nation's electrical supply -- will decrease by between 4 and 16 percent in the US and 6 to 19 percent in Europe from 2031 to 2060 due to lack of cooling water.

'Most comprehensive' genetic analysis of maize plant will help raise yields, expand its range
The most comprehensive analysis to date of the maize genome has just been published.

Rhythmic firing of nerve cells involved in body's movements
A new model for understanding how nerve cells in the brain control movement may help unlock the secrets of the motor cortex, a critical region that has long resisted scientists' efforts to understand it, researchers report June 3 in Nature.

New hope for migraine sufferers
New hope has arrived for migraine sufferers following a Griffith University study with the people of Norfolk Island.

Maize diversity discoveries may help ease world's hunger pangs
Researchers at the University of California, Davis, report that ancient farmers had a stronger impact on the evolution of maize, or corn, than modern plant breeders have had on the grain -- now one of the world's top production crops.

A different drummer: Stanford engineers discover neural rhythms drive physical movement
In a significant departure from earlier models, neural engineers and neuroscientists working at Stanford University have developed a new model for the brain activity underlying arm movements.

Scientists complete most comprehensive genetic analysis yet of corn
An interdisciplinary team, led by researchers at Cornell University and the US Department of Agriculture-Agricultural Research Service, today published the most comprehensive analysis to date of the corn genome.

US and European energy supplies vulnerable to climate change - Nature Climate Change
Higher water temperatures and reduced river flows in Europe and the United States in recent years have resulted in reduced production, or temporary shutdown, of several thermoelectric power plants, resulting in increased electricity prices and raising concerns about future energy security in a changing climate.

Larger refuges needed to sustain success of transgenic corn
For Bt corn to remain effective against rootworms, the authors of a new article in the Journal of Economic Entomology recommend increasing refuge requirements to 50 percent for corn producing one Bt protein and 20 percent for corn producing two Bt proteins.

Study suggests expanding the genetic alphabet may be easier than previously thought
A new study led by scientists at the Scripps Research Institute suggests that the replication process for DNA -- the genetic instructions for living organisms that is composed of four bases (C, G, A and T) -- is more open to unnatural letters than had previously been thought.

New breast cancer drug halts tumor growth better than standard therapy
A new cancer treatment that links chemotherapy with an agent that homes in on specific breast cancer cells was significantly better than the current drug regimen at keeping patients' advanced tumors from progressing, according to results from a phase III clinical trial led by Kimberly Blackwell, M.D., of the Duke Cancer Institute.

Lower income patients less likely to participate in cancer clinical trials
Lower-income cancer patients are less likely to participate in cancer clinical trials, according to a study presented at the American Society of Clinical Oncology 2012 meeting. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
