CAMBRIDGE, MA -- If at first you don't succeed, try, try again.

A new study from MIT reveals that babies as young as 15 months can learn to follow this advice. The researchers found that babies who watched an adult struggle at two different tasks before succeeding tried harder at their own difficult task, compared to babies who saw an adult succeed effortlessly.

Chronic tissue inflammation resulting from obesity is an underlying cause of insulin resistance and type 2 diabetes. But the mechanism by which this occurs has remained cloaked, until now.

In a paper, published in the journal Cell on September 21, University of California San Diego School of Medicine researchers identified exosomes -- extremely small vesicles or sacs secreted from most cell types -- as the missing link.

Too much dietary manganese -- an essential trace mineral found in leafy green vegetables, fruits and nuts -- promotes infection of the heart by the bacterium Staphylococcus aureus ("staph").

The findings, reported this week in the journal Cell Host & Microbe, add to the evidence that diet modifies risk for infection. The discovery also suggests that people who have excess levels of tissue manganese, including those who consume dietary supplements with high concentrations of the metal, may be at increased risk for staph infection of the heart.

Cold Spring Harbor, NY - In a major step forward in research, scientists at Cold Spring Harbor Laboratory (CSHL) today publish in Cell a discovery about the molecular-genetic basis of neuronal cell types. Neurons are the basic building blocks that wire up brain circuits supporting mental activities and behavior.

LOS ANGELES (Sept. 21, 2017) -- For years, medical investigators have tried and failed to develop vaccines for a type of staph bacteria associated with the deadly superbug MRSA. But a new study by Cedars-Sinai investigators shows how staph cells evade the body's immune system, offering a clearer picture of how a successful vaccine would work.

Staph frequently causes skin infections but occasionally can lead to deadly conditions such as sepsis, pneumonia and bloodstream infections, particularly in hospitalized patients whose immune systems could be weakened by illness.

Diet and exercise may improve treatment outcomes in pediatric cancer patients, according to a study at The University of Texas MD Anderson Children's Cancer Hospital.

A diet that includes plenty of colorful vegetables and fruits may contain compounds that can stop colon cancer and inflammatory bowel diseases in pigs, according to an international team of researchers. Understanding how these compounds work on a molecular level could be an initial step toward finding treatments for people with cancer, they added.

BOSTON-- Routine and rapid hepatitis C virus (HCV) testing among young adults who use injection drugs improves life expectancy and may provide a good use of limited resources, according to new research out of Boston Medical Center, in partnership with the Boston Public Health Commission. The findings are published online ahead of print in the journal Clinical Infectious Diseases.

Marijuana is the most commonly abused drug in the world, and the advent of synthetic cannabinoids creates additional challenges to the society because of their higher potency and ability to escape drug detection screenings. Scientists from Japanese sleep institute have a warning for the society about a danger coming from cannabinoid abuse.

New Rochelle, NY, September 21, 2017--Researchers in China who assessed self-monitoring of blood glucose (SMBG) behavior among nearly 19,000 patients with type 2 diabetes treated with oral medications reported very low SMBG rates both before and after the patients began treatment with basal insulin, although the data showed an increase in mean SMBG frequency after 6 months and the percentage of patients who never monitored their blood glucose decreased.
