5 Hazards Astronauts Face in Human Spaceflight

5 Hazards of Human Spaceflight

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized hazards astronauts will encounter on a continual basis into five classifications. Pooling the challenges into categories allows for an organized effort to overcome … Read more

Spice (Synthetic Marijuana) Withdrawal Symptoms More Severe Than Cannabis

Cannabis Marijuana Bag

The new study looked at withdrawal symptoms people experienced from the drug ‘Spice,’ which contains synthetic drugs originally designed to mimic the effects of cannabis. New research from the Addiction and Mental Health Group at the University of Bath highlights challenges for people trying to give up the drug ‘Spice.’ Research published on September 17, … Read more

Lipitor May Be Effective Treatment for Ulcerative Colitis

Colon With Ulcerative Colitis

Statins may be effective treatment for patients with ulcerative colitis. There may be good news for the nearly 1 million people battling ulcerative colitis, a type of inflammatory bowel condition with no real cure: Statins, a commonly prescribed cholesterol-lowering drug, seem to be an effective, if unexpected, treatment for the condition, according to a new … Read more

Subtle Cloud Shadows Cue Mini-Migrations

Subtle Cloud Shadows Cue Mini-Migrations

Measurements of light intensity (white lines) and zooplankton abundance (black line) with ocean depth (z, in meters) show that when cloud shadows prevent sunlight from reaching as deep in the ocean, zooplankton swim up to stay in water with their preferred brightness. When clouds thin or pass by, zooplankton swim back down. Model results (purple … Read more

Layered Graphene with a Twist Displays Unique Quantum Confinement Effects in 2-D

Twisted Graphene Concept

Understanding how electrons move in 2-D layered material systems could lead to advances in quantum computing and communication. Scientists studying two different configurations of bilayer graphene—the two-dimensional (2-D), atom-thin form of carbon—have detected electronic and optical interlayer resonances. In these resonant states, electrons bounce back and forth between the two atomic planes in the 2-D … Read more

How Much Water Should I Drink? We Asked Five Experts

Drinking Water Health

Eight seems like a lot… Do I have to drink eight glasses of water per day? Everyone knows humans need water and we can’t survive without it. We’ve all heard we should be aiming for eight glasses, or two liters of water per day. This target seems pretty steep when you think about how much … Read more

Extensive Chemical Composition Mapping Reveals Carbon-Rich, Organic Birth Environments of Planets

Extensive Chemical Composition Mapping Reveals Carbon-Rich, Organic Birth Environments of Planets

This composite image of ALMA data from the young star HD 163296 shows hydrogen cyanide emission laid over an artist’s impression of a starfield. The MAPS project zoomed in on hydrogen cyanide and other organic and inorganic compounds in planet-forming disks to gain a better understanding of the compositions of young planets and how the … Read more
