Safely Viewing a Solar Eclipse

A solar eclipse will be visible across North America for 2 to 3 hours on Monday, August 21, 2017. Watching the moon slowly block out the sun is a rare opportunity but should be attempted with caution.

Georgia Fried is into roller derby, the contact sport on roller skates, so she knows all about how things can get bumped. Such was the case when she made her college decision.

Civil Unrest After Freddie Gray’s Death Harms Health in Baltimore Mothers

The April 2015 civil unrest associated with Freddie Gray’s death while in police custody caused a significant spike of stress in mothers of young children living in affected neighborhoods, according to new research from the University of Maryland School of Medicine (UM SOM). The research, conducted before, during and after the period of civil unrest, found that the number of mothers with depressive symptoms increased from an average of 21% before the incident to an average of 31% during the acute period, spiking to 50% in August 2015. Mothers also reported concerns about disruptions in daily routines such as eating, sleeping and shopping, all of which can undermine maternal wellbeing and negatively affect parenting behaviors and subsequently, child development.

Pulses of Electrons Manipulate Nanomagnets and Store Information

Skyrmions are a kind of nanomagnet, comprised of a spin-correlated ensemble of electrons acting as a topological magnet on certain microscopic surfaces. The precise properties, like spin orientation, of such nanomagnets can store information. But how might you go about moving or manipulating these nanomagnets at will to store the data you want? New research demonstrates such read/write ability using bursts of electrons, encoding topological energy structures robustly enough for potential data storage applications. The researchers report their work this week in Applied Physics Letters.

Kaleidoscope of Colors Reveals Complex Biological Processes

Researchers have developed a technique that uses the vibration of chemical bonds to produce specific colors that allow them to simultaneously observe, in cells and tissues, as many as 24 interacting molecules--each with a distinct color.

NASA's Hubble Sees Martian Moon Orbiting the Red Planet

While photographing Mars, NASA's Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the moon's orbital path.

Small Survey: Most Primary Care Physicians Can't Identify All Risk Factors for Prediabetes

Johns Hopkins researchers who distributed a survey at a retreat and medical update for primary care physicians (PCPs) report that the vast majority of the 140 doctors who responded could not identify all 11 risk factors that experts say qualify patients for prediabetes screening. The survey, they say, is believed to be one of the first to formally test PCPs' knowledge of current professional guidelines for such screening.

Scientists Identify New Way Cells Turn Off Genes

For some developmental genes one allele must stay silent, otherwise debilitating syndromes and cancers can arise. HHMI Investigator Yi Zhang and his colleagues have uncovered a new imprinting mechanism cells use to keep these genes quiet in mice.
