Today's Science News
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.
