Today's Science News

Farming needs to be global focus

Farming needs to be global focus

The world's most prominent agricultural scientists and leaders underscored how neglecting agriculture in the Copenhagen agreement could lead to widespread famine and food shortages in the years ahead.

Hazard depends on origin of fish

A research team has confirmed a higher presence of the parasite Anisakis spp in anchovies of the Atlantic South East coast and the Mediterranean North West coast.

Study sheds light on evolution

Research shows that human beings are biologically complex because of the way humans evolved to cope with redundancies arising from duplicate genes.

Pharmacology

Antibiotics laced dissolving dressing

A scientist has developed a new wound dressing based on fibres she engineered - fibers that can be loaded with drugs like antibiotics to speed up the healing process, and then dissolve when they've done their job.

Why certain drug combinations backfire

Researchers have found that the answer lies in the way some antibiotic drugs influence a bacterial cell's gene expression levels.

Innovative analytical technology for higher efficiency

The hi-tech startup Anagnostics Bioanalysis develops analytical technologies for routine applications in drug discovery and medical research.

Nanotechnology

Exotic electric properties of graphene

The hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire.

Small optical force can budge nanoscale objects

Researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometres.

Universal programmable quantum processor

Researchers have demonstrated the first "universal" programmable quantum information processor able to run any program allowed by quantum mechanics.

Environment

Sea stars bulk up to beat the heat

A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom.

Sponges recycle carbon to give life to coral reefs

Coral reefs support some of the most diverse ecosystems on the planet, yet they thrive in a marine desert. So how do reefs sustain their thriving populations?

Climate variability and dengue incidence

Research demonstrates associations between local rainfall and temperature and cases of dengue fever, which affects an estimated fifty million people per year worldwide.

Biotechnology

Better tests for TB, HIV, and malaria

A researcher has highlighted the poor quality of published studies that evaluate the accuracy of diagnostic tests for 3 major killer infectious diseases (TB, HIV/AIDS and malaria).

Hoping for a fluorescent basket case

Researchers describe in detail how new virus particles assemble at the membrane of infected cells, and are released to attack healthy cells nearby.

Alzheimer's disease and chronic heart failure

Researchers report evidence from studies in animals and humans supporting a link between Alzheimer's disease and chronic heart failure.

Genetics

Treating heart disease with your own cells

The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk.

Chromosomes dance and pair up

Meiosis - the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell - is a major crossroads in all organisms reproducing sexually.

Largest gene study of childhood IBD

International research team has identified five new gene regions of childhood-onset inflammatory bowel disease, including one involved in a biological pathway that helps drive the painful inflammation.

Medical

Pushing the brain to find new pathways

A recent article argues that health practitioners believe their clients need more time and motivation to reclaim lost functions, such as the use of an arm, hand or leg.

Need for emergency airway surgery reduced

Be prepared, that old Boy Scout motto, is being applied with great success to operating room patients whose anatomy may make it difficult for physicians to help them breathe during surgery.

Why consumers turn to alternative medicine

Alternative health remedies are increasingly important in the health care marketplace. A new study explores how consumers choose among the many available remedies.
