Internal clocks drive plant growth

Hybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers.

New pain-killing chemical pathway

Marijuana kills pain by activating a set of proteins known as cannabinoid receptors, which can also regulate appetite, inflammation, and memory. The body also has chemicals known as endocannabinoids.

New strategy for broad spectrum anti-viral drugs

Bavituximab, an anti-viral drug, shows promise as a new strategy to fight viral diseases, including potential bioterrorism agents.

Wiring in the brain influences personality

According to scientists, connections between the nerves is one factor determining whether a person welcomes a change or tends to avoid anything new.

Sweet molecule could lead us to alien life

Scientists have detected an organic sugar molecule that is directly linked to the origin of life, in a region of our galaxy where habitable planets could exist.

How plants adapt to climate

Researchers have found that the formation stomata is controlled by a specific signalling pathway that blocks activity of a single protein required for stomata development.

The evolution of gene regulation

Scientists have shed light on some of the processes that regulate genes and they also have shed light on the evolution of the DNA regions that regulate genes.

Potassium loss may promote diabetes

Researchers have discovered that a drop in blood potassium levels caused by diuretics could be the reason why people on those drugs are at risk for developing type 2 diabetes.

Nutrients in water benefits agriculture

Researchers have studied nitrate levels in irrigation water from the Seymour Aquifer for the past three years, and have found nitrates can be as high as 40 parts per million.

Bacterial decision-making deciphered

Scientists have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function.

Brain awake while sleeping

Researchers demonstrated that non-REM sleep should not be viewed as a stage of constant and continuous brain activity decrease.

Range of tests for influenza viruses

Oxoid offers a range of valuable diagnostic tools for the detection of respiratory disease caused by influenza virus Types A and B.

Identification of blood samples

Traditionally alphanumeric tubes have been manufactured in clear polypropylene. Micronic has introduced a new range of white, flat bottom alphanumeric tubes for storage of blood samples.

Biological sample concentrator

Featuring a high displacement pump, the miVac Duo biological sample concentrator removes water up to 40% faster than similar concentrators and is extremely quiet.

Media shows careless streak with medical coverage

Media coverage of clinical trials does not contain the elements readers require to make informed decisions. A comparison of the coverage received by pharmaceutical and herbal remedy trials has revealed the problem.

Binge drinking may drive heart disease

As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke.

Rescue robot exercise

A rescue robot exercise was recently held in which about three dozen robots were tested by developers and first responders in order to develop a standard suite of performance tests.

Nanoscale stress test

Researchers have demonstrated their ability to measure relatively low levels of stress or strain in regions of a semiconductor device as small as 10 nanometres across.

Synthetic virus supports a bat origin for SARS

In an effort to understand how SARS-CoV may have jumped from bats to humans, a team of investigators has now generated a synthetic SARS-like bat coronavirus.

Winter flu, summer bacteria

Researchers have discovered that serious infections caused by gram-negative bacteria can go up as much as 17 percent with every 10 degree increase in seasonal temperature.
