Mechanism connects early binge drinking to adult behaviors
Science Daily - 19 Nov 2019 01:29
Intermittent exposure to high levels of alcohol in adolescent animals leads to increased levels of microRNA-137 in the brains of adults. Blocking microRNA-137 helps to reverse or the lasting effects of youth drinking, su...
Switching to renewable energy could save thousands of lives in Africa
Science Daily - 18 Nov 2019 23:03
New research finds that if Africa chooses a future powered by fossil fuels, nearly 50,000 people could die prematurely each year from fossil fuel emissions by 2030, mostly in South Africa, Nigeria and Malawi.
HIV drug exposure in womb may increase child risk of microcephaly, developmental delays
Science Daily - 18 Nov 2019 20:54
Children born to women on HIV therapy containing the drug efavirenz were 2 to 2.5 times more likely to have microcephaly, or small head size, compared to children born to women on regimens of other antiretroviral drugs, ...
AI could transform how we monitor the structural health of civil infrastructure
Science Daily - 18 Nov 2019 20:53
Scientists have developed a new machine learning algorithm (AI) that could transform the way we monitor major infrastructure - such as dams and bridges.
'Bad cholesterol' is only as unhealthy as its composition
Science Daily - 18 Nov 2019 20:53
New research shows that a particular subclass of low-density lipoproteins (LDL) is a much better predictor of potential heart attacks than the mere presence of LDL.
People in counties with worse economies are more likely to die from heart disease
Science Daily - 18 Nov 2019 20:52
Communities in the United States that experienced the most economic distress in the wake of the Great Recession saw a significant increase in death rates from heart disease and strokes among middle-aged people. While the...
Opioid prescription doses are increasingly being tapered, often more rapidly than recommended
Science Daily - 18 Nov 2019 19:08
Stigma and safety fears have made daily dose tapering of opioid prescriptions more common. New research, however, shows tapering can occur at rates as much as six times higher than recommended, putting patients at risk o...
Experimental cholesterol-lowering drug effective at lowering bad cholesterol, study shows
Science Daily - 18 Nov 2019 18:41
Twice-yearly injections of an experimental cholesterol-lowering drug, inclisiran, were effective at reducing low-density lipoprotein (LDL) cholesterol, often called bad cholesterol, in patients already taking the maximum...
Side effects mild, brief with single antidepressant dose of intravenous ketamine
Science Daily - 18 Nov 2019 18:41
Researchers found that a single, low-dose ketamine infusion was relatively free of side effects for patients with treatment-resistant depression. Widespread off-label use of intravenous subanesthetic-dose ketamine has ra...
Clearing damaged cells out of the body helps heal diabetics' blood vessels
Science Daily - 18 Nov 2019 16:25
New research shows that ramping up one of the body's waste disposal system, called autophagy, helps heal the blood vessels of diabetics.
'Gay' Penguin Couple Had No Egg of Their Own. So They Stole One.

Adolescent drinking increases anxiety and alcohol abuse risk later in life
Neuroscience News - 19 Nov 2019 01:07
Teenage binge drinking is linked to altered gene expression in the brain, specifically the central nucleus of the amygdala. Adolescent rats exposed to alcohol had increased levels of miR-137, resulting in lower expressio...
Blowing bubbles: Scientist confirms novel way to launch and drive current in fusion plasmas
Phys.org - 19 Nov 2019 00:55
