Engineers have made a breakthrough in an 80-year-old quandary in quantum physics, paving the way for the development of new materials that could make electronic devices smaller and cars more energy efficient.
Scientists trying to find a way to better help patients protect themselves against harm from a heart attack are taking their cues from cardiac patients. The work on “ischemic preconditioning” mirrors a perplexing curiosity that physicians have long observed in their patients: When faced with a heart attack, people who have had a previous one [...]

DNA recovered from ancient caribou bones reveals a possible link between several small unique caribou herds and a massive volcanic eruption that blanketed much of the Alaskan Yukon territory in a thick layer of ash 1,000 years ago, researchers report.

For the first time researchers from the U.S. and abroad have shown a single-dose HIV DNA vaccine can induce a long-lasting HIV-specific immune response in nonhuman primates, a discovery that could prove significant in the development of HIV vaccines.

Mechanical engineers have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon. The end result is a diamond-like carbon material mass-produced at the nanoscale that doesn’t wear.

A mathematics professor is using math to develop a new computer model that can be easily manipulated by other scientists and doctors to predict how different environmental, medical, or physical changes to a person’s body will affect their sleep. Their model will also provide clues to the most basic dynamics of the sleep-wake cycle.

Promiscuous females may be the key to a species’ survival, according to new research. The study could solve the mystery of why females of most species have multiple mates, despite this being more risky for the individual.
An early study suggests that vitamin B3 or niacin, a common water-soluble vitamin, may help improve neurological function after stroke. When rats with ischemic stroke were given niacin, their brains showed growth of new blood vessels, and sprouting of nerve cells which greatly improved neurological outcome. Now research is underway to investigate the effects of [...]

Researchers from Hungary and the UK have developed a single-dose H5N1 influenza vaccine that induces a protective level of immunity against infection in healthy adult and elderly volunteers. The vaccine is the first single-dose regimen to be tested in elderly subjects and it fulfills all European Union and U.S. licensing criteria offering a promising influenza [...]
