| Gene that helps honey bees find flowers (and get back home) discovered  | Honey bees don't start out knowing how to find flowers or even how to get around outside the hive. Before they can forage, they must learn to navigate a changing landscape and orient themselves to the sun. In a new study, researchers report that a regulatory gene known to be involved in the detection of novelty in vertebrates also kicks into high gear in the brains of honey bees when they are learning how to find food and bring it home. | Read More »  Gene therapy gives mice broad protection to pandemic flu strains, including 1918 flu  | Researchers have developed a new gene therapy to thwart a potential influenza pandemic. They demonstrated that a single dose of an adeno-associated virus expressing a broadly neutralizing flu antibody into the noses of animal models gives them complete protection and substantial reductions in flu replication when exposed to lethal strains of H5N1 and H1N1 flu virus. These were isolated from samples associated from historic human pandemics – the infamous 1918 flu pandemic and another from 2009. | Read More » Even shorter bouts of high-intensity exercise improve physical fitness in inactive men  | It is a commonly held perception that getting in shape and staying there requires hard work and hours upon hours of training. Now, new research shows the opposite – just four minutes of vigorous activity three times per week is enough to make previously inactive men fitter and more healthy. | Read More » Safe for stroke patients to continue blood thinners before minor surgical procedures  | It is is likely safe to continue taking blood thinners before minor procedures such as dental procedures, cataract surgery or dermatologic procedures, according to a new guideline from the American Academy of Neurology. | Read More » Clear photos in dim light: New sensor a thousand times more sensitive than current camera sensors  | Cameras fitted with a new revolutionary sensor will soon be able to take clear and sharp photos in dim conditions, thanks to a new image sensor. | Read More » Give barefoot running the boot?  | Barefoot running has been making headlines ever since 1960, when a shoeless Abebe Bikila set a new world-record marathon time at the Rome Olympics. Even manufacturers have muscled in on the trend over the years, with most now offering their own version of 'barefoot' or 'minimalist' shoes. | Read More » Newly discovered hormone makes ovaries grow  | A newly discovered hormone produced by the eggs of human females may improve the effectiveness of current fertility treatments for women and possibly lead to entirely new treatments altogether. Researchers have identified a new hormone called "R-spondin2" that promotes follicle development and stimulates ovary growth. | Read More » Live rabbit wears contact lenses with light-emitting diode: New class of transparent, stretchable electrodes developed  | Scientists have demonstrated that a live rabbit could wear contact lenses fitted with inorganic light-emitting diode with no side effects. This new class of hybrid transparent and stretchable electrode paves the way for flexible displays, solar cells, and electronics. | Read More » Rounded stones on Mars evidence of flowing water  | Observations by NASA's Mars rover Curiosity have revealed areas with gravel and pebbles that are characteristic of a former riverbed. Researchers have analyzed their shapes and sizes and the rounded pebbles clearly show that there has been flowing water on Mars. | Read More » | |
