Nagging negative thoughts - and striving for perfection - keep teenagers awake at night, raising their chance of becoming depressed and anxious, a new study shows.

An online study of almost 400 adolescents aged 14 to 20 years confirmed the link, leading sleep researchers at Flinders University to recommend alternative treatments for repetitive negative thinking and perfectionism in dealing with delayed sleep and mental health problems among teenagers.

Some intriguing physics can be found at the interfaces between fluids, particularly if they are straddled by particles like proteins or dust grains. When placed between un-mixable fluids such as oil and water, a variety of processes, including inter-molecular interactions, will cause the particles to move around. These motions are characterised by the drag force experienced by the particles, which is itself thought to depend on the extent to which they distort fluid interfaces.

Joint research conducted by The Nature Conservancy and the Kunming Institute of Botany, Chinese Academy of Sciences calculated the carbon-storing power of global soils and showcased approaches like agroforestry designed to capitalise on untapped potential.

WOODS HOLE, Mass. -- It's not spring in New England until the herring are running. From late February to early April, two species of herring --alewife and blueback herring--return from the ocean and swarm the region's ponds and streams, seeking the waters in which they were born.

WASHINGTON, D.C. (March 16, 2020)--Latino/a adolescents with a family member who was detained or deported beginning as early as 2017 were at high risk of suicidal thoughts, early alcohol use, and risky behaviors that can lead to school failure and chronic health problems. The findings were published today in JAMA Pediatrics.

Acne treatment including the highly effective acne medication isotretinoin should be made more readily available despite reports of its association with depression and teen suicide. That's the implication of a study just published in the Journal of the American Academy of Dermatology.

Isotretinoin has been linked to depression and suicide. But UCR researcher Misaki Natsuaki, one of the study's authors, said severe acne itself, when left untreated, poses a serious risk for depression and anxiety.

There are plenty of good reasons to make sure children get enough sleep, but their parents' evening peace is nowhere near the most important one.

"If we make sure our children get enough sleep, it can help protect them from mental health problems," says Bror M. Ranum, a PhD candidate at the Norwegian University of Science and Technology's (NTNU) Department of Psychology.

RIVERSIDE, Calif. -- How does the brain form "fear memory" that links a traumatic event to a particular situation? A pair of researchers at the University of California, Riverside, may have found an answer.

Using a mouse model, the researchers demonstrated the formation of fear memory involves the strengthening of neural pathways between two brain areas: the hippocampus, which responds to a particular context and encodes it, and the amygdala, which triggers defensive behavior, including fear responses.

Study results appear today in Nature Communications.

As oceans absorb more carbon dioxide, they are becoming increasingly acidic and shifting the delicate balance that supports marine life. How species will cope with ocean acidification and the other consequences of global climate change is still very much unknown and could have sweeping consequences.

Researchers from the University of Washington School of Aquatic and Fishery Sciences have discovered that ocean acidification impacts the ability of some oysters to pass down "memories" of environmental trauma to their offspring.

East Hanover, NJ. March 12, 2020. Among the many challenges to independence and quality of life after spinal cord injury, two complications have emerged as top priorities for researchers - neurogenic bowel and neurogenic bladder. With funding from the Craig H. Neilsen Foundation, researchers formulated a framework for planning and executing the research needed in these areas, and established recommendations for translating research findings into practical recommendations for community use by individuals with spinal cord injury.

The group headed by Dr. Julia Brailovskaia published their results in the journal "Computers in Human Behavior" from 6. March 2020.

DALLAS (SMU) - "Even if she doesn't say it, I know it's my fault that my mother gets sad."

Kids who believe comments like this - assuming blame for their mom's sadness or depression - are more likely to face depression and anxiety themselves, a new study led by SMU has found.

Nearly 94% of defendants in Cuyahoga County drug court have been exposed to trauma and many suffer from symptoms of post-traumatic stress disorder (PTSD), according to a new Case Western Reserve University study.

"These findings tell us that we need to not only treat the disease of addiction, but also the underlying mental-health issues that so often coincide with them," said Margaret Baughman, co-author of the study and a senior research associate at the Center on Trauma and Adversity at the university's Jack, Joseph and Morton Mandel School of Applied Social Sciences.

Many surveys of American adults have revealed that they worry about political issues and are concerned for the future of the United States. But what about children and teenagers?

A novel technology has been developed for hydrogen production from the process, which involves electron that is produced during the decomposition of biomass such as waste wood. The result produced after biomass decomposition is a high value-added compound, and it is a two-stone technology that improves the efficiency of hydrogen production.
