A study found that stress, anxiety and depression during the first few weeks of the pandemic were associated with less and lower quality sleep. In a survey of more than 900 twins, about half of the respondents reported no change in sleep patterns, but 32.9% reported decreased sleep. Another 29.8% reported sleeping more. The researchers found that any change in sleep was connected to self-reported mental health issues, though more strongly associated with decreased sleep.

Green hydrogen, a source of clean energy that can be generated without using fossil fuels, has recently gained immense attention as it can be potentially used to promote carbon neutrality. Korean researchers have succeeded in improving the efficiency of unitized regenerative fuel cells that can be used to efficiently produce green hydrogen and generate power.

A recent study by Nagoya University researchers revealed that microRNAs in urine could be a promising biomarker to diagnose brain tumors. Their findings have indicated that regular urine tests could help early detection and treatment of brain tumors, possibly leading to improved patient survival.

When delivering moms require caesarians or their newborns need neonatal care, some families may spend as much as $10,000 out-of-pocket, according to a new Michigan Medicine-led study.

The fast-food industry spent $5 billion on advertising in 2019, and the advertisements disproportionately targeted Black and Hispanic youth, according to new research published today by the Rudd Center for Food Policy and Obesity at the University of Connecticut. The new report, Fast Food FACTS 2021, finds that the industry's annual ad spending in 2019 increased by over $400 million since 2012, and that children and teens were viewing on average more than two fast food TV ads per day.

Weddell seals, the southernmost born mammal, are known as champion divers. But they don't begin life that way. Cal Poly researchers examined the development of diving behavior in Weddell seal pups and found that they time their dives with their mother but likely do not learn to forage at that time. Instead, they focus their early efforts on learning to swim and navigate under the sea ice.

Findings from a small study detailing the treatment of myocarditis-like symptoms in seven people after receiving a COVID-19 vaccine in the U.S. are published today in the American Heart Association's flagship journal Circulation.

A destructive pest beetle is edging closer to Australia as biological controls fail, destroying home gardens, plantations and biodiversity as they surge through nearby Pacific islands.

When animals are hot, they eat less. This potentially fatal phenomenon has been largely overlooked in wild animals, explain researchers from The Australian National University (ANU).

Recently, inspired by setaria's hydrophobic leaves, Professor GAO Minrui's team from University of Science and Technology of China developed Cu catalyst composed of sharp needles which possesses high level of hydrophobicity and stability.

Researchers from Osaka University, along with international collaborators in Europe, have identified Thrombospondin-2 as a serum biomarker that confirms and stratifies the progressive complications of nonalcoholic fatty liver disease. This research may form the basis of a new noninvasive approach that can provide an early warning system for nonalcoholic steatohepatitis and advanced fibrosis and may predict progression to cirrhosis, liver failure and even cancer.

Researchers from University of Tsukuba, in collaboration with scientists in Germany, have created a mouse model of restrictive cardiomyopathy, a disease in which the heart muscle becomes stiff and the heart is unable to properly fill with blood. Their data suggest that the disease results from the accumulation of mutant BAG3 protein, which interferes with the protein quality control system and the machinery for breaking down and recycling damaged proteins, disrupting the heart muscle components.

Electrons are ubiquitous among atoms, subatomic tokens of energy that can independently change how a system behaves -- but they also can change each other. An international research collaboration found that collectively measuring electrons revealed unique and unanticipated findings.

Inhibiting necroptosis, a form of cell death, could yield a new treatment approach for chronic obstructive pulmonary disease (COPD), an inflammatory lung condition also known as emphysema, new research shows. The study, by a team of Australian and Belgian researchers, revealed elevated levels of necroptosis in patients with COPD. By inhibiting necroptosis activity in the lung tissue of COPD patients the researchers found a significant reduction in chronic airway inflammation and lung damage.

Conservationists have long warned of the dangers associated with bears becoming habituated to life in urban areas. Yet, it appears the message hasn't gotten through to everyone.News reports continue to cover seemingly similar situations -- a foraging bear enters a neighbourhood, easily finds high-value food and refuses to leave. The story often ends with conservation officers being forced to euthanize the animal for public safety purposes.

Since 2005, the guidelines for the care of unconscious cardiac arrest patients have been to cool the body temperature down to 33 degrees Celsius. A large, randomised clinical trial led by Lund University and Region Skåne in Sweden has shown that this treatment does not improve survival. The study is published in the New England Journal of Medicine.

African American mothers continue to have the lowest breastfeeding rates, even as the breastfeeding rates have risen in the US over the past 25 years.

New research published in BMJ Open shows that community pharmacy could play a 'key clinical role' in the future of COVID-19 vaccination programmes, according to a study led by Aston University in Birmingham, UK, in collaboration with UK and international researchers.

The role of people infected with malaria without showing symptoms presents a hidden risk to efforts to control the disease after they were found to be responsible for most infections in mosquitoes, according to a study published in The Lancet Infectious Diseases.

A new University of Washington study of requests and donations to the popular crowdfunding site GoFundMe, along with Census data, shows stark inequities in where the money went and how much was donated.
