Viagra could be used as a safe treatment for heart disease, finds new research. A study reveals that long-term daily treatment of Viagra can provide protection for the heart at different stages of heart disease, with few side effects.
Improving household electricity access in India over the last 30 years contributed only marginally to the nation's total carbon emissions growth during that time, according to a new study.
Researchers have successfully transplanted "organoids" of functioning human intestinal tissue grown from pluripotent stem cells in a lab dish into mice– creating an unprecedented model for studying diseases of the intestine.
New research will help batteries resist overcharging, improving the safety of electronics from cellphones to airplanes. This work focused on the design, synthesis and testing of organic compounds that can be incorporated into the electrolytes of lithium-ion batteries to improve their safety profiles.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics– a breakthrough that will help develop drugs that can effectively tackle infections in the future. It’s hoped this insight will help scientists to develop new antibiotics with a much lower risk of resistance, and to choose the best medicines for specific outbreaks.
A study led by psychology researchers has found that people who play action video games such as Call of Duty or Assassin’s Creed seem to learn a new sensorimotor skill more quickly than non-gamers do.
The World Health Organization has admitted that it botched attempts to stop the now-spiraling Ebola outbreak in West Africa, blaming factors including incompetent staff and a lack of information. The UN health agency acknowledged that, at times, even its own bureaucracy was a problem.
Scientists have found hidden signatures in the brains of people in a vegetative state that point to networks that could support consciousness even when a patient appears to be unconscious and unresponsive. The study could help doctors identify patients who are aware despite being unable to communicate.
Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research that has implications for health care.
Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to researchers who found in a new study that drinking sugary drinks was associated with cell aging.
The daily trimming of fingernails and toenails to make them more aesthetically pleasing could be detrimental and potentially lead to serious nail conditions. This is according to researchers who have devised equations to identify the physical laws that govern nail growth, and used them to throw light on the causes of some of the most common nail problems, such as ingrown toe nails, spoon-shaped nails and pincer nails.

Scientists have found evidence for a huge mountain range that sustained an explosion of life on Earth 600 million years ago. The mountain range was similar in scale to the Himalayas and spanned at least 2,500 kilometers of modern west Africa and northeast Brazil, which at that time were part of the supercontinent Gondwana.
A geochemist studying Samoan volcanoes has found evidence of the planet’s early formation still trapped inside the Earth. Known as hotspots, volcanic island chains such as Samoa can hold ancient primordial signatures from the early solar system that have somehow survived billions of years.
Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades. Now, a team has found that miniature solar flares called nanoflares— and the speedy electrons they produce— might partly be the source of that heat, at least in some of the hottest parts of the Sun's corona.
