Weight-reduction surgery for severely obese adults may prevent second heart attack, death

Science Daily - 26/10/2020
Adults with severe obesity (BMI >35) and a prior heart attack who undergo weight-reduction surgery may lower their risk of a second heart attack, major cardiovascular event, heart failure and death. The effect weight-reduction surgery had on the patients' weight, blood pressure, cholesterol and A1C (a Type 2 diabetes marker) seems to play a role in decreasing the risk of heart attack and death.

Single brain region links depression and anxiety, heart disease, and treatment sensitivity

Science Daily - 26/10/2020
Over-activity in a single brain region called the subgenual anterior cingulate cortex (sgACC) underlies several key symptoms of mood and anxiety disorders, but an antidepressant only successfully treats some of the symptoms. A new study suggests that sgACC is a crucial region in depression and anxiety, and targeted treatment based on a patient's symptoms could lead to better outcomes.

Nearly one in three young adults in the US does not know common stroke symptoms

Science Daily - 26/10/2020
Nearly 30% of U.S. adults younger than 45 don't know all five of the most common stroke symptoms, according to a recent survey. Hispanic adults, people not born in the U.S. and less educated young adults were among the most likely to be unaware of stroke symptoms. Stroke incidence and hospitalizations are rising among young adults in the U.S.

NASA's OSIRIS-REx spacecraft collects significant amount of asteroid

Science Daily - 24/10/2020
Two days after touching down on asteroid Bennu, NASA's OSIRIS-REx mission team received on Thursday, Oct. 22, images that confirm the spacecraft has collected more than enough material to meet one of its main mission requirements -- acquiring at least 2 ounces (60 grams) of the asteroid's surface material.

New imaging method reveals HIV's sugary shield in unprecedented detail

Science Daily - 24/10/2020
Scientists have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system. Mapping these shields will give researchers a more complete understanding of why antibodies react to some spots on the virus but not others, and may shape the design of new vaccines that target the most vulnerable sites on viruses.

PTSD and alcohol abuse go hand-in-hand, but males and females exhibit symptoms differently

Science Daily - 24/10/2020
Through intricate experiments designed to account for sex-specific differences, scientists have zeroed-in on certain changes in the brain that may be responsible for driving alcohol abuse among people with PTSD. In studies with rodents, researchers found that males and females exhibit their own distinct symptoms and brain features of PTSD and alcohol use disorder. Such differences are not typically accounted for in laboratory-based studies yet could lead to more successful clinical treatments.

Metal deposits from Chinese coal plants end up in the Pacific Ocean

Science Daily - 24/10/2020
Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a research team. The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
