Research shows that taking a cholesterol-lowering drug for five years in middle age can lower heart and death risks for decades afterward. The benefits seem to grow over time and may last for life.
The government's worst-case scenario forecast for the Ebola epidemic in West Africa won't happen, a U.S. health official has said. In September, the CDC estimated the number of people sickened by the Ebola virus could explode to as many as 1.4 million by mid-January without more help. But, things have changed.
Internal bleeding is a leading cause of death on the battlefield, but a new, injectable material developed by a team of researchers could buy wounded soldiers the time they need to survive by preventing blood loss from serious internal injuries.
Flexible electronic sensors based on paper— an inexpensive material— have the potential to cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper.
A new study in mice has shown that our natural gut-residing microbes can influence the integrity of the blood-brain barrier, which protects the brain from harmful substances in the blood. The find provides experimental evidence that our indigenous microbes contribute to the mechanism that closes the blood-brain barrier before birth.
Climate-change warning labels are coming to gas pumps in Berkeley, Calif., a city with a long history of green and clean policies. The Berkeley City Council has voted to draft a proposal by next spring that will put stickers on gas pumps citywide to warn consumers that burning fuel contributes to global warming.
Scientists report a new method for establishing whether chemical compounds are safe for human use without in vivo testing, based on so-called "molecular initiating events" at the boundary between chemistry and biology.
Scientists at the world's largest smasher announced today that they have discovered two new subatomic particles never seen before that could widen our understanding of the universe. The find could shed more light on how things work beyond the Standard Model physics theory explaining the basic building blocks of matter.
Truth shines a light into dark places. But sometimes to find that truth in the first place, it’s better to stay in the dark. That’s what recent findings show about methods for testing the safety of nanoparticles. It turns out that previous tests indicating that some nanoparticles can damage our DNA may have been skewed by inadvertent light exposure in the lab.
Blueberries are super stars among health food advocates, who tout the fruit for not only promoting heart health, better memory and digestion, but also for improving night vision. Scientists have taken a closer look at this latter claim and have found reason to doubt that the popular berry helps most healthy people see better in the dark.
With temperatures dipping, homeowners are firing up their heaters. But systems that require heating oil release fine particles outside that could have harmful health effects. Regulations to curb these emissions in New York City could save hundreds of lives, a new study has found.
The number of foreign exchange students studying at U.S. colleges and universities is at a record high, with nearly one-third coming from China. A report says nearly 900,000 international students were studying in the U.S. during the 2013-14 school year, up 8 percent from a year earlier.
A physics professor at the California Institute of Technology is suing the school, claiming she faced a "merciless campaign" of retaliation for telling the FBI that she suspected illegal activities at the university-managed NASA Jet Propulsion Laboratory.
A new security and safety technology system is being tested in 20 public schools in New York state. Gov. Andrew Cuomo announced this week that the schools in Oneida and Rockland counties will be the first to launch the program, called Mutualink K-12.
Online teaching has generated plenty of discussion in higher education, but it’s still used by a relatively small percentage of professors. A new study notes a more pronounced trend in teaching at colleges and universities lately: a greater move toward student-focused teaching practices such as class discussions and group learning, and a corresponding move away from lectures and other teacher-centered styles.
