(University of Miami Rosenstiel School of Marine & Atmospheric Science) Scientists studying nearly identical coral reef systems off Australia discovered something unusual on the reefs subjected to nearly exclusive fishing of sharks--fish with significantly smaller eyes and tails. Show More Summary
New research finds that PDL-1 expressed in antigen presenting cells - macrophages and dendritic cells found in the tumor microenvironment and in the nearby lymph nodes -- is a better indicator than PDL-1 in the tumor of who will respond to immunotherapy drugs.

(Reuters Health) - Girls who start menstruating before they’re 12 years old may have a greater risk of heart disease and stroke later in life than their peers who go through puberty later, a U.K. study suggests.
Scientists studying nearly identical coral reef systems off Australia discovered something unusual on the reefs subjected to nearly exclusive fishing of sharks—fish with significantly smaller eyes and tails. The study is the first field evidence of body shape changes in fish due to human-driven shark declines from overfishing. Show More Summary
(Reuters Health) - Mothers who nurse their babies now have another reason to continue as long as they can: longer periods of breastfeeding are associated with a lower risk of diabetes even decades later, a U.S. study suggests.
Scientists believe they may have discovered the cause of an epidemic that struck Mexico’s Aztec population in 1545, killing up to 15 million people. In a paper published in Nature Ecology & Evolution, they describe how DNA extractedShow More Summary
People who survive brain infection with West Nile virus can have neurological problems long after the virus is gone. A new study in mice suggests that such ongoing problems may be due to unresolved inflammation that hinders the brain's ability to repair damaged neurons and grow new ones. Show More Summary
Experiments with a small group of overweight men and women have added to evidence that "hunger hormone" levels rise and "satiety (or fullness) hormone" levels decrease in the evening. The findings also suggest that stress may increase hunger hormone levels more in the evening, and the impact of hormones on appetite may be greater for people prone to binge eating.
A team of researchers with the University of Oslo has found evidence that suggests human fleas and lice, not rodents, were behind the spread of the plague that killed millions of people over the course of several centuries. In theirShow More Summary
A novel imaging approach enables assessment of key nervous system deterioration in multiple sclerosis (MS), a new study in mice suggests. The research, “Development of a PET radioligand for potassium channels to image CNS demyelination,” was published in the journal Scientific Reports. Show More Summary
A UK study has found that regular surfers were three times more likely to have an antibiotic resistant strain of E. coli bacteria in their gut than non-surfers. This not only suggests surfers are more likely to be at risk from theseShow More Summary
Increase screening for women who start their periods at a young age or those reaching menopause early, experts suggest Women who start their periods at an early age, or experience an early menopause, are at greater risk of cardiovascular disease, new research suggests. Show More Summary
(BMJ) Starting periods early -- before the age of 12 -- is linked to a heightened risk of heart disease and stroke in later life, suggests an analysis of data from the UK Biobank study, published online in the journal Heart.
A provocative new study suggests that medieval plagues spread via fleas and lice on people.
A new study suggests that key geological markers align towards a start for the Anthropocene somewhere between 1952 to 1955, based on signals from nuclear testing and fossil fuel burning.
(Reuters Health) - Higher use of electronic media is tied to poorer sleep quality in children as young as three, a new study from Germany suggests.
A joint industry/academia study of a cancer target protein reveals unusual relation between binding site flexibility and drug-target lifetime. The results suggest a new strategy for drug discovery.
Can the teeth of 10 people solve a centuries-old mystery? According to a study published Monday in Nature Ecology and Evolution, perhaps. Its authors suggest that an epidemic that killed as many as 17 million people over the course of two outbreaks in the 16th century and had a hand...
(Society for Neuroscience) Psychotherapy may improve symptoms of psychiatric disorders by increasing activity in the medial prefrontal cortex, suggests a study of rats exposed to chronic stress. The research, published in JNeurosci, is a step toward understanding how the brain processes influenced by behavioral therapy may be targeted to improve treatment.
