Chikungunya challenge project announced

Washington - A challenge has been laid down for scientists. The contest aims to identify models that accurately forecast outbreaks of the mosquito spread viral disease chikungunya.

Microbes discovered 800 meters deep in Antarctica lake

Samples taken from an Antarctic lake 800 meters below the ice reveal an abundance of microbial life. The lake was the vast and mysterious Lake Whillans.

Chikungunya vaccine in development

An early-stage clinical trial into a vaccine for the virus chikungunya yields promising results, according to the authors of a new study.

CDC bird flu contamination caused by man rushing to a meeting

Atlanta - New evidence suggests that a Centers for Disease Control and Prevention (CDC) scientist who accidentally leaked H5N1 into a benign strain of avian influenza may have been rushing off to a meeting.

Octopus skin inspires sophisticated camouflage sensors

Cephalopod skin inspires engineers to design sheets of adaptive camouflage sensors. Inspired by the octopus, researchers have created sheets of sensors with a temperature-sensitive dye to mimic cephalopod camouflage.

Lab mice have 'lost' traits through domestication

A study of laboratory bred mice has revealed that some behavioral traits, like female aggression, have been lost with domestication.

Marburg virus drug shows promise

Monkeys infected with lethal doses of Marburg virus, as part of a laboratory study, were rescued by an experimental siRNA-based therapeutic.

Epigenetic patterns found with people who have Alzheimer’s

People with the neurodegenerative disease Alzheimer's are more likely to have certain epigenetic patterns than those without, according to a new study.

Hoopoes' eggs change color according to mother’s health

Biologists have discovered that preen gland secretion causes hoopoes’ eggs to change color, signalling about the health of the mother bird.

Ferroelectric materials show promise

Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics - remarkable materials that use built-in electric polarizations to read and write digital information.

Bacterial meningitis incidence falls in the U.S.

Advances in the prevention and treatment of bacterial meningitis appear to be paying dividends in the U.S. A new report has revealed a significant drop in prevalence and mortality following the introduction of new treatments.

Scientists study Amazon turtles that ‘talk,’ take care of young

MERS transmission link between bats and humans revealed

The mechanism used by Middle East Respiratory Syndrome (MERS) virus to transmit from bats to humans has been identified by researchers. The finding could be critical for preventing and controlling the spread of MERS and related viruses in humans.

Burial site for Black Death victims a first in Spain

Barcelona - When the Black Death plague hit Spain back in the 14th century, the population reportedly plummeted from around six million to a mere 2.5 million people. However, the first mass grave from that period has only now been discovered, in Barcelona.

New research to improve tuberculosis drugs

New clues to understanding how the most important medication for tuberculosis (TB) works may lead to a new generation of medicines to fight the virulent bacterium.

Fighting malaria by targeting genes

A new approach to preventing malaria by knocking out parasite's genes has been proposed. Biological engineers have demonstrated that a new genome-editing technique can disrupt a single parasite gene with a success rate of up to 100 percent.

American farmers fighting wheat fungus outbreak

This year's soft red winter wheat crop has been hit with fusarium head blight, a fungal disease that develops if it rains during the critical growing period for wheat. Known as "head scab," the disease will have a broad impact on farmers and consumers.

Can Ebola be treated with the blood of survivors?

As part of its bid to tackle Ebola, the World Health Organization (WHO) is considering a potential Ebola treatment that involves using the blood of people who have recovered from an infection to treat those still fighting the virus.

Treating cancer with bacteria shows promise

In a remarkable study, researchers have shown that injecting bacteria into a cancer tumor helped shrink it. Studies were first carried out on dogs, and then, with interesting results, on a female cancer patient.
