New ALMA observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black hole at the center of the Milky Way. This nebulous disk gives astronomers new insights into the workings of accretion: the siphoning of material onto the surface of a black hole. The results are published in the journal Nature.

Study offers comprehensive roadmap for regulating political activity by nonprofits
Beginning in the 1990s and increasingly today, nonprofits are delving into politics.

New approach optimizes use of future wave electricity generators during disaster
When hurricanes strike, loss of electricity ranks as one of the top concerns for relief workers. Blackouts lasting a week or more can hamper recovery efforts, shutter hospitals, threaten public health and disrupt transportation. The monthslong effort to restore power to Puerto Rico following the 2017 hurricane season has led to renewed interest in finding innovative ways to get affected power grids back online.

Psychedelic drugs: Would you accept a prescription?
In countries such as the UK, US and Australia, strict laws and international conventions prohibiting the use of psychedelic drugs have made it almost impossible to research how these drugs work, and how they might be used to heal instead of harm—until recently. These barriers—together with cost, ethics committees, ideologically driven myths and stigma—have delayed research into a promising area of medicine. But things are changing for the better, as evidence and unmet need are at last being recognised.

Study examines potential misuse of anti-anxiety medication
There is concern about the misuse of the sedative anti-anxiety medication alprazolam (Xanax) because of the "high" it can create. A new British Journal of Clinical Pharmacology study found that non-medical use of alprazolam in the United Kingdom is a significant issue, and it appears to be more prevalent in younger adults.

Economic downturns may affect children's mental health
Research linking economic conditions and health often does not consider children's mental health problems. In a new Health Economics study, investigators found that U.S. children's mental health worsened as the economy weakened. The use of special education services for emotional problems also rose when economic conditions worsened.
