e-Cigs May Hold Formaldehyde Risk

January 22, 2015 3:00 pm | by Associated Press, Marilynn Marchione | News | Comments

Using certain electronic cigarettes at high temperature settings could potentially release more formaldehyde, a cancer-causing chemical, than smoking traditional cigarettes does, new lab tests suggest. The research does not prove a health risk— it involved limited testing on just one brand of e-cigarettes and was done in test tubes, not people.

Travelers on Antibiotics May Spread Superbugs Globally

January 22, 2015 3:00 pm | by Oxford University Press | News | Comments

Taking antibiotics for diarrhea may put travelers visiting developing parts of the world at higher risk for contracting superbugs and spreading these daunting drug-resistant bacteria to their home countries. This is according to a new study that calls for greater caution in using antibiotics for travelers’ diarrhea, except in severe cases.

Experiments, Simulations Shed Light on Collagen’s Force

January 22, 2015 3:00 pm | by MIT, David Chandler | News | Comments

Research combining experimental work and detailed molecular simulations has revealed, for the first time, the complex role that water plays in collagen— a protein that is a component of tendons, bone, skin and other structural tissues in the body.

Supposed Cancer-promoting Enzymes Suppress Tumors

January 22, 2015 3:00 pm | by UC San Diego | News | Comments

Upending decades-old dogma, a team of scientists say enzymes— long categorized as promoting cancer— are, in fact, tumor suppressors and that current clinical efforts to develop inhibitor-based drugs should instead focus on restoring the enzymes' activities.

Dino-killing Asteroid Didn't Cause Global Firestorms

January 22, 2015 3:00 pm | by Univ. of Exeter | News | Comments

Scientists recreated the energy released from an extraterrestrial collision with Earth that occurred around the time that dinosaurs became extinct. They found that the intense, but short-lived, heat near the impact site could not have ignited live plants, debunking the theory that the impact led to global firestorms.

Rosetta Yields Closest-ever Look at Comet

January 22, 2015 3:00 pm | by Univ. of Maryland | News | Comments

On Nov. 12, 2014, the Rosetta mission made history when its Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this exciting technical achievement gained lots of headlines, it was only the beginning for researchers back on Earth who are receiving and analyzing comet data. The latest chapter in the story provides the closest and most detailed look at a comet that scientists have ever seen.

Eight Gene Mutations May Shed Light on Brain

January 22, 2015 7:00 am | by Univ. of Southern California | News | Comments

In the largest collaborative study of the brain to date, a global consortium of 190 institutions has identified eight common genetic mutations that appear to age the brain an average of three years. The discovery could lead to targeted therapies and interventions for Alzheimer’s disease, autism and other neurological conditions.

Two Sub-glacial Lakes Disappear Within Weeks

January 22, 2015 7:00 am | by The Ohio State Univ. | News | Comments

Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater pooled beneath the ice and then rapidly drained away. One lake once held billions of gallons of water and emptied to form a mile-wide crater in just a few weeks. The other lake has filled and emptied twice in the last two years.
