About The Study: In this survey study of 9,400 adults ages 18 to 64, a higher rate of respondents with self-reported post–COVID-19 condition (PCC; also known as long COVID) did not obtain needed health care in the past year because of cost compared with adults without PCC. Adults with PCC were also more likely to have unmet needs because of difficulties getting timely appointments or health plan authorization, among other challenges with health care institutions or health insurance. These findings suggest that improved health care access for adults with PCC may require developing clinical protocols and addressing insurance-related barriers.  Authors: Michael ...

About The Study: The largest increase in children’s recreational screen time during the pandemic was on weekdays, especially at the outset of the pandemic when schools were closed; this increase was greater than expected for age-related growth. Change in weekend screen time during the pandemic was not significant compared with weekday screen time. Once in-person school resumed, weekday screen time decreased versus that during the COVID-1 wave (spring 2020), although it remained consistently higher than pre-pandemic estimates and age-related expectations.  Authors: Sheri Madigan, Ph.D., of the University of Calgary in Calgary, Canada, is the corresponding ...

Nearly 20 percent of today’s electricity in the United States comes from nuclear power. The U.S. has the largest nuclear fleet in the world, with 92 reactors scattered around the country. Many of these power plants have run for more than half a century and are approaching the end of their expected lifetimes.  Policymakers are debating whether to retire the aging reactors or reinforce their structures to continue producing nuclear energy, which many consider a low-carbon alternative to climate-warming coal, oil, and natural gas.  Now, MIT researchers say there’s another factor to consider in weighing the future of nuclear power: ...

AURORA, Colo. (April 10, 2023) – Involuntary displacement of people experiencing homelessness will likely lead to a substantial increase in morbidity and mortality over a 10-year period. In a study, published today in the Journal of the American Medical Association (JAMA), researchers say practices such as encampment sweeps, bans, move-along-orders and cleanups that forcibly relocate individuals away from essential services will lead to substantial increases in overdose deaths, life threatening infections and hospitalizations. In coordination with the National Healthcare for Homeless Council, the Center for Disease Control and Prevention (CDC) and the National Foundation ...

Throughout a woman's reproductive life, the endometrium, the mucous membrane lining the uterus, goes through cyclical remodeling. It thickens during the menstrual cycle in preparation for embryo implantation, and it is shed during menstruation when there is no fertilization. Researchers at Baylor College of Medicine and collaborating institutions are investigating little-known factors directing uterine remodeling to advance the understanding of this process and provide new insights into fertility-associated gynecological conditions. They report today in the journal Developmental ...

An accretion disk is a colossal whirlpool of gas and dust that gathers around a black hole or a neutron star like cotton candy as it pulls in material from a nearby star. As the disk spins, it whips up powerful winds that push and pull on the sprawling, rotating plasma. These massive outflows can affect the surroundings of black holes by heating and blowing away the gas and dust around them. At immense scales, “disk winds” can offer clues to how supermassive black holes shape entire galaxies. Astronomers have observed signs of disk winds in many systems, ...

About The Study: This simulation modeling study of 23 U.S. cities projects that involuntary displacement of people experiencing homelessness who inject drugs may yield substantial increases in morbidity and mortality over a 10-year period. Involuntary displacement is estimated to worsen overdose and hospitalizations, decrease initiations of medications for opioid use disorder, and contribute to deaths. These findings have implications for the practice of involuntary displacement, as well as policies such as access to housing and supportive services, that could mitigate these harms.  Authors: Joshua A. Barocas, M.D., ...

For more than 100 million Americans who are obese, bariatric surgery may reverse complications related to diabetes, including regenerating damaged nerves, a Michigan Medicine study shows. A research team led by the University of Michigan Health Department of Neurology followed more than 120 patients who underwent bariatric surgery for obesity over two years after the procedure. They found that all metabolic risk factors for developing diabetes, such as high glucose and lipid levels, improved outside of blood pressure and total cholesterol, according to results published in Diabetologia. Investigators ...

In a pair of complementary studies, researchers took a close look at Luna moth (Actias luna) tails through the eyes of birds and female moths to test the tails’ role in predation and sexual selection. Scientists have known for about a decade that Luna moths — and other related silkmoths — use their long, trailing tails to misdirect bat attacks. “They have projections off the back of the hindwing that end in twisted, cupped paddles,” said Juliette Rubin, a doctoral student at the Florida Museum ...

The chemical industry has played a significant role in the development of society, but its impact on the environment has become a growing concern. Green chemistry and chemical engineering have opened up possibilities for sustainability through the transformation of renewable feedstocks into environmentally friendly chemicals. However, the inert bonds in molecules such as CO2 and N2 present challenges to their activation and conversion. Electrochemical conversion provides a promising carbon-neutral route to upgrading green chemical sources with inert bonds to chemicals and fuels under ambient conditions. Multicomponent electrocatalysts have advantages over monocomponent catalysts, ...

AMHERST, Mass. – Three engineers at the University of Massachusetts Amherst have invented a fabric that concludes the 80-year quest to make a synthetic textile modeled on Polar bear fur. The results, published recently in the journal ACS Applied Materials and Interfaces, are already being developed into commercially available products. Polar bears live in some of the harshest conditions on earth, shrugging off Arctic temperatures as low as -50 Fahrenheit. While the bears have many adaptations that allow them to thrive when the temperature plummets, since the 1940s scientists have focused on one in particular: their fur. How, the scientific community ...

ATLANTA—Plans are underway to add a seventh movable telescope to Georgia State University’s Center for High Angular Resolution Astronomy— known as the CHARA Array—that would increase the resolution, or the ability to see small objects, by a factor of three. Located at Mount Wilson Observatory in Southern California and operated by Georgia State, the new telescope will be connected using fiber optics to transport the starlight, a technique that will serve as a pathfinder ...

Mutations in our genes can lead to severe problems, like colon or liver cancer. But cancer is very complex. Mutations in the same genes can lead to different subtypes of tumors in different people. Currently, scientists don’t have a good way to produce such tumor subtypes for study in the lab. Now, Cold Spring Harbor Laboratory Assistant Professor Semir Beyaz has created a new method to model certain liver cancer tumor subtypes using the gene-editing tool CRISPR-Cas9. Genes contain the information our bodies need to create proteins. Highly similar proteins produced from the same gene are called isoforms. Different isoforms generate ...

So, mushroom-zombies recently took over a fictional world, but in real life, they’re really not so scary. These fungi range in shape from broad, plate-like portobellos and gangly enokis to a version resembling a giant, shaggy lion’s mane. And now scientists are finding ways to grow mushrooms on new materials, as well as incorporate them in more sustainable products. Below are some recent papers published in ACS journals that report insights into additional applications for mushrooms. Reporters can request free access to these ...

A new study by Case Western Reserve University PhD student Russell Engelman published in PeerJ Life & Environment attempts to address a persistent problem in paleontology – what were the size of Dunkleosteus and other late Devonian arthrodire placoderms. Arthrodire placoderms are extinct fishes with had armor covering their head and part of their torso, but like sharks the rest of their skeleton was made of cartilage, meaning most of their body did not preserve when they became fossilized.   Previous size estimates for Dunkleosteus were ...

Research Highlights: Analysis found that more than half of preeclampsia cases that occur during weeks 37-42 of pregnancy (called at-term preeclampsia) may be prevented with timed birth, such as a scheduled induction or Cesarean delivery. Planned labor inductions and Cesarean deliveries are already widely practiced for a range of reasons, however, they are seldom considered as an intervention to prevent at-term preeclampsia, which may be life-threatening.

Statement Highlights: A new American Heart Association scientific statement reviews research about racial and ethnic differences in cardiovascular risk factors among women in the U.S. In addition to traditional risk factors, women of underrepresented races or ethnicities experience challenges in the diagnosis and treatment of cardiovascular conditions due to language barriers, discrimination, difficulties in acculturation or assimilation, lack of financial resources or health insurance, or lack of access to health care. Women of racial and ethnic backgrounds other than white have been underrepresented ...

Sea levels along the U.S. Southeast and Gulf coasts have been rapidly accelerating, reaching record-breaking rates over the past 12 years, according to a new study led by scientists at Tulane University. In the study, published in Nature Communications, researchers said they had detected rates of sea-level rise of about a half an inch per year since 2010. They attribute the acceleration to the compounding effects of man-made climate change and natural climate variability.  “These rapid rates are unprecedented over at least the 20th century and they have been three times higher than the global average over the same period,” says Sönke ...

By using precision gene engineering techniques, researchers at the Earlham Institute in Norwich have been able to turn tobacco plants into solar-powered factories for moth sex pheromones.  Critically, they’ve shown how the production of these molecules can be efficiently managed so as not to hamper normal plant growth.  Pheromones are complex chemicals produced and released by an organism as a means of communication. They allow members of the same species to send signals, which includes letting others know they’re looking for love. Farmers can hang pheromone dispersers among their crops to mimic the signals ...
