Huntingtin Gene Crucial to Memory Development

August 13, 2014 11:50 am | News | Comments

It has been more than 20 years since scientists discovered that mutations in the gene huntingtin cause the devastating progressive neurological condition Huntington’s disease. Surprisingly little, however, has been known about the gene’s role in normal brain activity. Now, new research shows it plays a critical role in long-term memory.

Idiopathic Pulmonary Fibrosis: Hope, At Last

August 11, 2014 2:26 pm | by Cynthia Fox | Articles | Comments

There have been stunning “firsts” in research on idiopathic pulmonary fibrosis (IPF), a mysterious disease that stiffens and stills the lungs, killing half its victims in three years. In May, results of Phase 3 clinical trials on the first two effective drugs for IPF were published in the New England Journal of Medicine (NEJM). And in June, the first paper explaining IPF was published in Science Translational Medicine.

Scientists Unlock Key to Blood Vessel Formation

August 11, 2014 2:09 pm | News | Comments

Scientists from the University of Leeds have discovered a gene that plays a vital role in blood vessel formation, research which adds to our knowledge of how early life develops. The discovery could also lead to greater understanding of how to treat cardiovascular diseases and cancer.

Newly Discovered Heart Molecule Could Lead to Effective Treatment for Heart Failure

August 11, 2014 2:04 pm | News | Comments

Researchers have discovered a previously unknown cardiac molecule that could provide a key to treating, and preventing, heart failure. The newly discovered molecule provides the heart with a tool to block a protein that orchestrates genetic disruptions when the heart is subjected to stress, such as high blood pressure.

Like Cling Wrap, New Biomaterial Can Coat Burn Wounds and Block Infection

August 11, 2014 2:01 pm | News | Comments

Wrapping wound dressings around fingers and toes can be tricky, but for burn victims, guarding them against infection is critical. Today, scientists are reporting the development of novel, ultrathin coatings called nanosheets that can cling to the body’s most difficult-to-protect contours and keep bacteria at bay.

Solving a Sticky Problem with Fetal Surgery Using Glue Inspired by Sandcastle Worm

August 11, 2014 1:48 pm | News | Comments

In creating an adhesive patterned after glue produced by the lowly underwater sandcastle worm, researchers are reporting today that they may have solved the problem of premature births that sometimes result from fetal surgery. It also could open up numerous opportunities to safely perform more complex fetal surgeries in the future.

Making Cashews Safer for Those with Allergies

August 11, 2014 1:37 pm | News | Comments

For the millions of adults and children in the U.S. who have to shun nuts to avoid an allergic reaction, help could be on the way. Scientists are now developing a method to process cashews—and potentially other nuts—that could make them safer to eat for people who are allergic to them.

Wild Sheep Show Benefits of Putting Up with Parasites

August 8, 2014 12:47 pm | News | Comments

In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure an internal parasite strongly influences its reproductive success. The finding could provide the groundwork for boosting the resilience of humans and livestock to infection.

'Normal' Bacteria Vital for Keeping Intestinal Lining Intact

August 7, 2014 4:24 pm | by Einstein | News | Comments

Scientists at Albert Einstein College of Medicine of Yeshiva University have found that bacteria that aid in digestion help keep the intestinal lining intact. The findings could yield new therapies for inflammatory bowel disease (IBD) and a wide range of other disorders.

Biology Made Simpler with "Clear" Tissues

August 6, 2014 1:22 pm | News | Comments

In general, our knowledge of biology—and much of science in general—is limited by our ability to actually see things. Researchers who study developmental problems and disease, in particular, are often limited by their inability to look inside an organism to figure out exactly what went wrong and when. Now, thanks to techniques developed at Caltech, scientists can see through tissues, organs, and even an entire body.
