A clear, molecular view of how human color vision evolved

Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the evolution of human color vision.

Ability to balance on one leg may reflect brain health, stroke risk

Struggling to stand on one leg for less than 20 seconds was linked to an increased risk for stroke, small blood vessel damage in the brain, and reduced cognitive function in otherwise healthy people, a study has shown. One-legged standing time may be a simple test used to measure early signs of abnormalities in the brain associated with cognitive decline, cerebral small vessel disease and stroke.

Most commonly prescribed glaucoma drug reduces risk of vision loss by more than 50% over 2 years

“Medication to lower raised eye pressure has been used for decades as the main treatment for OAG to delay progressive vision loss. But, until now, the extent to which the most frequently prescribed class of pressure-lowering drugs (prostaglandin analogues) have a protective effect on vision was not known,” explains the lead author of a new study. “Our findings offer solid proof to patients and practitioners that the visual deterioration caused by glaucoma can be reduced using this treatment.”

Doctor who survived Ebola received experimental drug treatment

On 28 September, 2014, the 38-year old doctor, who was in charge of an Ebola virus treatment unit in Lakka, Sierra Leone, developed a fever and diarrhea. He tested positive for the virus on the same day. The doctor was airlifted to Frankfurt University Hospital on the 5th day of his illness and admitted to a specialized isolation unit. Within 72 hours of admission he developed signs of vascular leakage and severe multi-organ failure, including the lungs, kidneys, and gastrointestinal tract. He was placed on a ventilator and on kidney dialysis, and was given antibiotics together with a 3-day course of an experimental drug called FX06—a fibrin-derived peptide that has been shown to reduce vascular leakage and its complications in mice with Dengue hemorrhagic shock.

How llamas’ unusual antibodies might help in the fight against HIV/AIDS

Most vaccines work by inducing an immune response characterized by neutralizing antibodies against the respective pathogen. An effective HIV vaccine has remained elusive so far, but researchers have continued to make progress, often employing innovative methods. A new study reports that a combination of antibodies from llamas can neutralize a wide range of circulating HIV viruses.

Mutations need help from evolution to cause cancer

In addition to DNA damage, cancer depends on the slow degradation of tissue that allows cancer cells to out-compete healthy cells, a new study shows. “We show that mutations, although necessary, cannot promote blood cancer development without an age-altered tissue microenvironment,” the researchers write.

She was quick to embrace the step this week when President Barack Obama, a fellow Democrat no longer having to face an electorate, relaxed U.S. policy toward Cuba. While assailed by Republicans opposed to restoring ties with the communist-led island, the action has the power to solidify support for Democrats among increasingly influential Latino voters and appeal to voters in farm states like Iowa eager to do business in Havana. …
