County-level income inequality, social mobility, and deaths of despair in the US

JAMA Network Open

2023-07-12

(Press-News.org) About The Study: This study found that the joint exposure of unequal income distribution and lack of social mobility was associated with additional risks for deaths of despair (deaths from suicide, drug overdose, and alcohol-related liver disease), suggesting that addressing the underlying social and economic conditions is crucial in responding to the epidemic of deaths of despair.

Authors: Chun-Tung Kuo, Ph.D., of National Taiwan University in Taipei, is the corresponding author.

Trends in acute care use for mental health conditions among youth during pandemic

2023-07-12

About The Study: Into the second year of the pandemic, mental health emergency department visits increased notably among adolescent females, and there was an increase in prolonged boarding (waiting in an emergency department or medical inpatient unit) of youth awaiting inpatient psychiatric care. Interventions are needed to increase inpatient child psychiatry capacity and reduce strain on the acute mental health care system. Authors: Haiden A. Huskamp, Ph.D., of Harvard Medical School in Boston, is the corresponding author.

Study: The ocean’s color is changing as a consequence of climate change

2023-07-12

CAMBRIDGE, MA -- The ocean’s color has changed significantly over the last 20 years, and the global trend is likely a consequence of human-induced climate change, report scientists at MIT, the National Oceanography Center in the U.K., and elsewhere. In a study appearing today in Nature, the team writes that they have detected changes in ocean color over the past two decades that cannot be explained by natural, year-to-year variability alone. These color shifts, though subtle to the human eye, have occurred over 56 percent of the world’s oceans — an expanse that is larger than ...

DNA element with a murky past is borrowing cell’s repair machinery

2023-07-12

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell’s own machinery to achieve its goals. In a new work appearing online Wednesday in the journal Nature, a Duke University team has determined that retrotransposons hijack a little-known piece of the cell’s DNA repair function to close themselves into a ring-like shape and then create a matching double strand. The finding upends 40 years of conventional wisdom saying these rings were just a useless by-product of bad gene copying. It may also offer new insights into cancer, viral infections and immune responses. Retrotransposons are segments ...

Plastic pollution on coral reefs increases with depth and mostly comes from fishing activities, Nature study finds

2023-07-12

SAN FRANCISCO, CA (July 12, 2023) — In a paper published today in Nature, researchers from the California Academy of Sciences, University of São Paulo, University of Oxford, University of Exeter, and other collaborators reveal the extent of plastic pollution on coral reefs, finding that debris increases with depth, largely stems from fishing activities, and is correlated with proximity to marine protected areas. Through underwater visual surveys spanning more than two dozen locations across the Indian, Pacific, and Atlantic ...

Mast cells as a sensor: Enigmatic immune cells help to avoid harmful allergens

2023-07-12

The function of mast cells, which are part of the immune system, is still a mystery. Scientists at the German Cancer Research Center (DKFZ) have now shown in mice: mast cells function as a sensor that signals the animals to avoid antigens, including harmful allergens, and thereby protect themselves from health-threatening inflammatory reactions. The findings were published in the journal Nature. Mast cells are found primarily in tissues that separate the outside and inside worlds of the body, such ...

Detailed map of the heart provides new insights into cardiac health and disease

2023-07-12

In a new study, published today (12 July) in Nature, researchers have produced the most detailed and comprehensive human Heart Cell Atlas to date, including the specialised tissue of the cardiac conduction system - where the heartbeat originates. The multi-centre team is led by the Wellcome Sanger Institute and the National Heart and Lung Institute at Imperial College London, and has also presented a new drug-repurposing computational tool called Drug2cell, which can provide insights into the effects of drugs on heart rate. This study is part of the international Human Cell Atlas* ...

Second year of COVID pandemic brought spike in child mental health visits to ED

2023-07-12

The number of young people in the United States visiting hospital emergency departments for mental health crises increased sharply during the second year of the COVID-19 pandemic, according to a study led by researchers from the Department of Health Care Policy in the Blavatnik Institute at Harvard Medical School. The findings are published Jul 12 in JAMA Psychiatry. These results come amidst growing national concern about a crisis in youth mental health and provide important new details about how young people with mental health problems such as self-harm ...

Global study details microplastics contamination in lakes and reservoirs

2023-07-12

LAWRENCE, Kan. — Around 14 million tons of plastic end up in the ocean every year. But that is not the only water source where plastic represents a significant intrusion. “We found microplastics in every lake we sampled,” said Ted Harris, associate research professor for the Kansas Biological Survey & Center for Ecological Research at the University of Kansas. “Some of these lakes you think of as clear, beautiful vacation spots. But we discovered such places to be perfect examples of the link between plastics and humans.” Harris ...

A foundation that fits just right gives superconducting nickelates a boost

2023-07-12

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University say they’ve found a way to make thin films of an exciting new nickel oxide superconductor that are free of extended defects. Not only does this improve the material’s ability to conduct electricity with no loss, they said, but it also allows them to discover its true nature and properties, both in and out of the superconducting state, for the first time. Their first look at a superconducting nickel oxide, or nickelate, that does ...

New study using human fibroid cells supports use of green tea compound as treatment for uterine fibroids

2023-07-12

In a pre-clinical, proof-of-concept study from Johns Hopkins Medicine, researchers found that epigallocatechin gallate (EGCG), a green tea compound with powerful antioxidant properties, could be promising for both treating and preventing uterine fibroids. Results of the study, first posted online May 25 in Scientific Reports, add to growing evidence that EGCG may reduce fibroid cell growth. The study was specifically designed to identify the biochemical mechanisms responsible for EGCG action in fibroid cells. The investigators emphasize that their study involves human fibroid cells grown in the laboratory and treated with EGCG extract to explore the possibility of oral EGCG supplementation ...
