A team of scientists are exploring how this species of mollusk reacts to environmental shifts in the ocean.


Imaging Study Shows Brain Activity May Be as Unique as Fingerprints

October 13, 2015 9:58 am | by Yale University | Comments

A person’s brain activity appears to be as unique as his or her fingerprints, a new imaging study shows. These brain “connectivity profiles” alone allow researchers to identify individuals from the fMRI images of brain activity of more than 100 people, according to the study published Oct. 12 in the journal Nature Neuroscience.


Building a Better Liposome

October 13, 2015 9:51 am | by Carnegie Mellon University | Comments

Using computational modeling, researchers have come up with a design for a better liposome. Their findings, while theoretical, could provide the basis for efficiently constructing new vehicles for nanodrug delivery.


Breast Cancer Drug Beats Superbug

October 13, 2015 9:44 am | by UC San Diego | Comments

Researchers have found that the breast cancer drug tamoxifen gives white blood cells a boost, better enabling them to respond to, ensnare and kill bacteria in laboratory experiments. Tamoxifen treatment in mice also enhances clearance of the antibiotic-resistant bacterial pathogen MRSA and reduces mortality.


Dissolving Stent for Heart Arteries Passes First Large Test

October 13, 2015 9:37 am | by Marilynn Marchione, AP Chief Medical Writer | Comments

Now you see it, now you don't. A new type of heart stent that works like dissolving stitches, slowly going away after it has done its job, passed its first major test in a large study, doctors said Monday.


New Device Quickly Detects Gluten in Your Food

Tests of a similar nature take 15 to 20 minutes to find traces of gluten in food. 


New Papers Discuss Details for Possible 'Exercise Pill'

October 13, 2015 8:18 am | by Ryan Bushey, Associate Editor | Comments

Two recently published papers have laid the groundwork for creating a potential ‘exercise pill.’


Babies Born During Summer Tend to Be Healthier Adults

October 13, 2015 8:18 am | by Bevin Fletcher, Associate Editor | Comments

A new study has found that women born during summer months are more likely to be healthy as adults.  Part of the reason could be due to getting more sun during pregnancy, which can lead to higher birth weight and later onset of puberty, said authors of the study, which was published in the journal Heliyon.


A Whale of a Tale

October 12, 2015 9:32 am | by Harvard University | Comments

The great whales are carnivores, feeding on tiny, shrimp-like animals such as krill. Moreover, the microbes that live in whales’ guts — the microbiome — resemble those of other meat-eaters. But scientists now have evidence that the whale microbiome shares traits with that of creatures not known to eat meat: cows.


How the Brain Keeps Time

October 12, 2015 9:28 am | by Anne Trafton, MIT News Office | Comments

Keeping track of time is critical for many tasks, such as playing the piano, swinging a tennis racket, or holding a conversation. Neuroscientists have now figured out how neurons in one part of the brain measure time intervals and accurately reproduce them.


Lab-grown 3D Intestine Regenerates Gut Lining In Dogs

October 12, 2015 9:23 am | by Johns Hopkins University | Comments

 Working with gut stem cells from humans and mice, scientists have successfully grown healthy intestine atop a 3-D scaffold made of a substance used in surgical sutures.


Analyzing Protein Structures in Their Native Environment

October 12, 2015 9:12 am | by Anne Trafton, MIT News Office | Comments

Proteins can fold in different ways depending on their environment. These different configurations change the function of the protein; misfolding is frequently associated with diseases such as Alzheimer’s and Parkinson’s. Using a new technique known as sensitivity-enhanced nuclear magnetic resonance (NMR), researchers have shown that they can analyze the structure that a yeast protein forms as it interacts with other proteins in a cell.


California Adopts Strictest Limits on Livestock Antibiotics

October 12, 2015 8:53 am | by Juliet Williams, Associated Press | Comments

California has adopted the toughest limits in the nation on the use of antibiotics in healthy livestock, barring their routine use to prevent illness or promote growth.


Gene Editing: Research Spurs Debate Over Promise vs. Ethics

October 12, 2015 8:49 am | by Lauran Neergaard, AP Medical Writer | Comments

The hottest tool in biology has scientists using words like revolutionary as they describe the long-term potential: wiping out certain mosquitoes that carry malaria, treating genetic diseases like sickle-cell, preventing babies from inheriting a life-threatening disorder.
