Lakes are bodies of water fed by rainfall, snowmelt, rivers and groundwater, through which, Earth is teeming with life. Lakes also contain critical geologic records of past climates. Though Mars is a frozen desert today, scientists have shown that Mars contains evidence of ancient lakes that existed billions of years ago, which could contain evidence for ancient life and climate conditions on the red planet...

Strong alternating magnetic fields can be used to generate a new type of spin wave that was previously just theoretically predicted. This was achieved for the first time by a team of physicists from Martin Luther University Halle-Wittenberg (MLU). They report on their work in the scientific journal Nature Communications and provide the first microscopic images of these spin waves.

The basic idea of spintronics is to use a special property of electrons – spin – for various electronic applications such as data and information technology. The Spin is the intrinsic angular momentum of electrons that produces a magnetic moment...

In the study, researchers estimated that three years of multivitamin supplementation roughly translated to a 60-percent slowing of cognitive decline (about 1.8 years).

Could taking a daily multivitamin help maintain cognitive health with aging and possibly prevent cognitive decline? According to new research from Wake Forest University School of Medicine, conducted in collaboration with Brigham and Women’s Hospital in Boston, taking a daily supplement may improve cognition in older adults, but additional studies are needed to confirm these findings before any hea...

As NASA prepares to usher in a new form of planetary defense, one Johns Hopkins engineer will be eagerly awaiting the big collision that she is helping orchestrate.

Elena Adams, the mission systems engineer at the Johns Hopkins Applied Physics Laboratory, and her team will spend the next two weeks carefully observing Didymos, a double-asteroid system that poses no threat to Earth and yet will be the target of NASA’s Double Asteroid Redirection Test—a first-of-its-kind, proof-of-concept mission that will intentionally crash a spacecraft into an asteroid’s moonlet to deflect it away from its course.

“During the day of impact, I’ll be more of a conductor, making sure that all of the orchestra is following the beat and playing their parts,” said Adams, who will discuss the mission...
