The Large High Altitude Air Shower Observatory (LHAASO) has accurately measured the brightness over 3.5 orders of magnitude of the standard candle in high-energy astronomy, thus calibrating a new standard for ultra-high-energy (UHE) gamma-ray sources. The standard candle is the famous Crab Nebula, which evolved from the "guest star" recorded by the imperial astronomers of China's Song Dynasty.

In a small study of gymnasts with ulnar (elbow) collateral ligament injury, orthopedic sports medicine researchers found that the athletes can be treated successfully and can return to competition. The research was presented at the American Orthopedic Medicine Society- Arthroscopy Association of North America Combined 2021 Annual Meeting.

A new study shows that individuals with bipolar disorder who are exposed to significant trauma may be at greater risk for suicide death, suggesting that a diagnosis of post-traumatic stress disorder (PTSD) or genetic predisposition to PTSD could be important factors in suicide prevention.

This research provides a broad perspective on the use of PVBs in Ontario, and on the use of nerve blocking treatments in general. There has been a concern for several years about the over use of these procedures; however, this is the first study to systematically document the impact on health care utilization and opioid use.

People who get type 2 diabetes need to gain control of their blood-sugar levels -- fast. The years immediately after diagnosis are strikingly critical in terms of their future risk for heart attacks and death. This is shown by a joint study from the Universities of Gothenburg and Oxford.

A new University of Central Florida study indicates that smaller loggerhead and green sea turtles are nesting on Florida beaches than in the past; however, researchers aren't sure why. The findings, published this month in the journal Ecosphere, give clues to the status of the turtles, which is important to researchers who are monitoring the population health of the threatened species.

Rude behavior is a common form of insensitive and disrespectful conduct that harms employees' performance in the workplace. In a new study, researchers examined the impact of rude behavior on how individuals make critical decisions. The study found that in certain situations, these behaviors can have deadly consequences.

A new study suggests that better reporting of adverse effects in drug trials would help inform the public of any potential harms.

Researchers from the University of Sussex have determined the structure of a tiny multi-protein biological machine, furthering our understanding of human cells and helping to enhance research into cancer, neurodegeneration and other illnesses.

If you've ever been to an eye doctor, there's a good chance you've felt the sudden puff of air to the eye that constitutes a traditional test for glaucoma. It's no one's favorite experience, but the puff is non-invasive and harmless. Scientists use a similar method to test learning and memory in animals and humans.

When it comes to what users share on Twitter, women and users who never attended college voluntarily disclose more personal information than users from other socioeconomic and demographic backgrounds -- potentially making these populations more susceptible to online privacy threats, according to a recent study led by the Penn State College of Information Sciences and Technology.

Throughout the pandemic, air sensors watched during lockdowns as air pollution fell in residential and commercial areas, and then as pollution rose again with reopenings. The changing levels, the researchers found, which behaved differently in residential and commercial parts of the city, show where pollution is coming from and how it might change in the future under different policies.

Thyroid dysfunction is known to be connected with the development of cardiovascular diseases. While thyroid hormone-mimicking drugs help treat lipid-related diseases, the definitive causal association between thyroid function and serum lipid level remains unclear. Now, in a study published in Chinese Medical Journal, researchers from China have established the missing link between the two. The results of their genetic epidemiology based-study highlight the possibility of using thyroid functions for predicting and managing lipid-related diseases.

Scientists at the University of Groningen have trained an Artificial Intelligence system to recognize a specific pattern in skin biopsies of patients with the blistering disease epidermolysis bullosa acquisita. The pattern is characteristic of a specific variant of the disease which can cause scarring of the skin and mucous membranes, and may lead to blindness. The new system is easy to use and is better than most doctors in making the diagnosis.

A new study has linked a July 2015 ceasefire of conflict violence in Colombia with better pregnancy outcomes for women who conceived after the ceasefire began. Giancarlo Buitrago of Universidad Nacional de Colombia in Bogotá, Colombia, and Rodrigo Moreno-Serra of the University of York, U.K., present these findings in the open-access journal PLOS Medicine.

Fifty-five percent of Midwest university students had tried a plant-based meat alternative and attributed this choice to the enjoyment of new food, curiosity about the products, and environmental concern, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier.

In a new study assessing the potential of a single-dose, intranasal COVID-19 vaccine, a team from the University of Iowa and the University of Georgia found that the vaccine fully protects mice against lethal COVID-19 infection. The vaccine also blocks animal-to-animal transmission of the virus.

A team of the University of Barcelona has analysed for the first time what the dry and hot periods could be like in the area of the Pyrenees. Under an intermediate scenario, there would not be a rise in long-lasting dry episodes, but temperatures would rise during these periods. Also, summer no-rain periods would last an average of five more, and they would go with a rise of temperatures 6ºC over the current ones.

When people see a toothbrush, a car, a tree -- any individual object -- their brain automatically associates it with other things it naturally occurs with, allowing humans to build context for their surroundings and set expectations for the world. By using machine-learning and brain imaging, researchers measured the extent of the "co-occurrence" phenomenon and identified the brain region involved. The findings appear in Nature Communications.

The recent extreme heat in the Western United States and Canada may seem remarkable now, but events like these are made more likely, and more severe, under climate change. The consequences are likely to be far-reaching, with overwhelmingly negative impacts on land and ocean ecosystems, biodiversity, food production and the built environment.
