A comet called Atlas is currently heading toward the sun, and it just might put on a really good show in a couple of months. Discovered last December by the Asteroid Terrestrial-impact Last Alert system in Hawaii (thus the name ATLAS for the comet), the comet has been growing much brighter than experts had predicted. If it manages to hold its shape as it moves nearer to the sun, it could grow brighter than Venus.

Shortly after its discovery, ATLAS began growing brighter than expected—a lot brighter. So bright that it can now be seen by amateur astronomers with binoculars. It is expected to reach its peak brightness at the end of May...

People who live more than 110 years, called supercentenarians, are remarkable not only because of their age, but also because of their incredible health. This elite group appears resistant to diseases such as Alzheimer’s, heart disease and cancer that still affect even centenarians. However, we don’t know why some people become supercentenarians and others do not.

Now, for the first time, scientists have reprogrammed cells from a 114-year-old woman into induced pluripotent stem cells (iPSCs)...

More than 35 million Americans take statin drugs daily to lower their blood cholesterol levels. Now, in experiments with human cells in the laboratory, researchers at Johns Hopkins Medicine have added to growing evidence that the ubiquitous drug may kill cancer cells and have uncovered clues to how they do it.

The findings, say the researchers, enhance previous evidence that statins could be valuable in combating some forms of cancer. In unrelated studies, other Johns Hopkins Medicine researchers have studied how statins may cut the risk for aggressive prostate cancer.

“There have been epidemiological indications that people who take statins long term have fewer and less aggressive cance...

A room-temperature bonding technique for integrating wide bandgap materials such as gallium nitride (GaN) with thermally-conducting materials such as diamond could boost the cooling effect on GaN devices and facilitate better performance through higher power levels, longer device lifetime, improved reliability and reduced manufacturing costs. The technique could have applications for wireless transmitters, radars, satellite equipment and other high-power and high-frequency electronic devices.

The technique, called surface-activated bonding, uses an ion source in a high vacuum environment to first ...
