UCLA study uncovers biological clock that may shed light on why our bodies age

Everyone grows older, but scientists don't really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process.

Discovery sheds light on how forces outside of cells get translated into internal signals

Johns Hopkins researchers used suction to learn that individual "molecular muscles" within cells respond to different types of force, a finding that may explain how cells "feel" the environment and appropriately adapt their shapes and activities.

Binge drinking increases atherosclerotic progression, stroke mortality risk in men

A Finnish population-based study showed that binge drinking was associated with increased atherosclerotic progression in an 11-year follow-up of middle-aged men. The progression of atherosclerosis was increased among men who consumed 6 drinks or more on one occasion.

Breast milk purchased over Internet contained bacteria that can cause illness in infants

Results from a study led by researchers at Nationwide Children's Hospital found more than three-fourths of breast milk samples purchased over the Internet contained bacteria that can cause illness, and frequently exhibited signs of poor collection, storage or shipping practices.

Adolescents vaccination for pertussis linked with lower rates of infant hospitalizations

Widespread vaccination of adolescents for pertussis was associated with lower rates of infant hospitalizations for the respiratory infection than would have been expected had teens not been inoculated according to new research in Pediatrics.

Scientists find unexpected molecular switch that prompts blood stem cells aging

Scientists report in Nature they have found a novel and unexpected molecular switch that could become a key to slowing some of the ravages of getting older as it prompts blood stem cells to age.

Study finds inherited GATA3 gene variation increases risk of developing pediatric leukemia

Research led by St. Jude Children's Research Hospital scientists has linked an inherited gene variation to a nearly four-fold increased risk of developing a pediatric acute lymphoblastic leukemia (ALL) subtype that is associated with a poor outcome.

Clarified role of signal-relay proteins may help explain spread of cancer

Cell biologists at The Johns Hopkins University have teased apart two integral components of the machinery that causes cells to move. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell.

Study: Skin tanning gene linked to higher risk for testicular cancer in white men

A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by scientists from the U.S. National Institutes of Health and the University of Oxford in England.

Oral nutritional supplements linked with decreased probability of 30-day hospital readmission

In the U.S., one in five Medicare patients is readmitted to a hospital each year at an estimated cost of $17.5 billion annually.i To reduce this impact, the Affordable Care Act (ACA) has introduced hospital penalties based on readmissions conditions that commonly affect patients aged 65 and older - including acute myocardial infarction, congestive heart failure and pneumonia.

CBT more effective in reducing symptoms of health anxiety

Cognitive behavioural therapy (CBT) is substantially more effective than standard care at reducing symptoms of health anxiety in medical patients, and can be delivered by non-specialist staff with minimal training at little extra cost.

Cavity restoration predicts dental bleeding, calculus

Dental assessment of young adults in Brazil has linked posterior restoration of cavities to an increased risk for gingival bleeding and dental calculus.

Schizophrenic hippocampal abnormalities blamed on glutamate

Elevated glutamate levels correlate with reduced tissue volume in the hippocampus of patients with schizophrenia, a study shows.

Study: Sleep allows brain to flush out damaging molecules linked with neurodegeneration

A good night's rest may literally clear the mind. Using mice, researchers showed for the first time that the space between brain cells may increase during sleep, allowing the brain to flush out toxins that build up during waking hours.

Study shows how two miRNAs regulate FOXP2 gene implicated in speech, language impairments

A study led by Xiaoching Li, PhD, at the LSU Health Sciences Center New Orleans Neuroscience Center of Excellence, has shown for the first time how two tiny molecules regulate a gene implicated in speech and language impairments as well as autism disorders, and that social context of vocal behavior governs their function.

Students who use false IDs are at increased risk for alcohol use disorder

A study found that almost two-thirds of college students used a fake ID at least once to obtain alcohol. Students who used false ID more often indirectly increased their risk for alcohol use disorder, according to a new longitudinal study in Alcoholism: Clinical and Experimental Research.

Liverpool Care Pathway provides little clinical benefit for dying cancer patients

The first randomised trial to test the effectiveness of the Liverpool Care Pathway (LCP) programme, developed and implemented widely to support patients as they near death, has found little clinical benefit compared with standard care for cancer patients dying in hospital.

Air pollution hampers fetal growth

Exposure to common air pollutants and traffic during pregnancy significantly increases the risk of restricted fetal growth, even at levels well below those stipulated in current European Union (EU) air-quality directives, according to one of the largest studies of its kind, published in The Lancet Respiratory Medicine.
