An international team anchored by the Event Horizon Telescope (EHT) Collaboration, which is known for capturing the first image of a black hole in the galaxy Messier 87, has now imaged the heart of the nearby radio galaxy Centaurus A in unprecedented detail.

What The Study Did: Researchers examined racial/ethnic disparities in outpatient visit rates to 29 physician specialties in the United States.

What The Study Did: This study included a meta-analysis that combined the results of 74 studies with 2.7 million participants to estimate how common globally dementia is in people younger than age 65.

What The Study Did: The association between daily coffee consumption and the risk of cardiac arrhythmias was evaluated in this study.

What The Study Did: These results suggest that substantial proportions of Latinx immigrants have immigration concerns about engaging in COVID-19-related testing, treatment and contact tracing.

What The Study Did: The experiences, perspectives and needs of transgender young people in accessing health care are described in this review of 91 studies.

What The Study Did: This study investigated the association between time spent cycling and the risk of death from cardiovascular disease or any other cause among people with diabetes.

A potentially game-changing treatment for people with, or at risk of, blood clots has been found effective by an international team of researchers led by McMaster University.

CT scans for patients with concussion provide critical information about their risk for long-term impairment and potential to make a complete recovery - findings that underscore the need for physician follow-up.

Scientists from the University of Graz, Kanzelhöhe Observatory, Skoltech, and the World Data Center SILSO at the Royal Observatory of Belgium, have presented the Catalogue of Hemispheric Sunspot Numbers. It will enable more accurate predictions of the solar cycle and space weather, which can affect human-made infrastructure both on Earth and in orbit.

An experimental drug reported in Nature Communications suggests that a "path is clearly achievable" to treat currently untreatable cases of cystic fibrosis disease caused by nonsense mutations. This includes about 11 percent of cystic fibrosis patients, as well as patients with other genetic diseases, including Duchenne muscular dystrophy, β-thalassemia and numerous types of cancers, that are also caused by nonsense mutations.

Firefighters at the centre of the battle against the massive Fort McMurray, Alberta wildfire in 2016 have persistent lung damage, according to new findings published by a University of Alberta occupational health research team. The firefighters had more than double the risk of developing asthma compared with the general population. They also exhibited a number of changes in lung function tests supportive of an effect on the lungs, including greater lung hyperreactivity and increased thickening of the bronchial wall.

Researchers at Children's Hospital of Philadelphia (CHOP) have developed a novel method for producing new antibiotics to combat resistant bacteria. Through an approach that would target bacteria with an antibiotic that is masked by a prodrug, which the bacteria would themselves remove, the researchers identified a method that would allow for development of new, effective antibiotics that could overcome issues of resistance. The findings were published today in eLife.

New research shows that modelling hyperspectral- and thermal-based plant traits can help in the early detection of Phytophthora-induced symptoms in oak decline.

When it comes to making eggs, female flies and female humans are surprisingly similar. And that could be a boon for women seeking better birth control methods, a UConn researcher reports in the July 5 issue of PNAS.

The July issues of two of the American Psychiatric Association journals, The American Journal of Psychiatry and Psychiatric Services are available online.

Researchers have found that when fruit bats forage in the city (Tel Aviv), they are much more exploratory and enjoy the diversity of urban life, visiting a variety of fruit trees every night and tasting as wide a variety of foods as possible. In contrast, rural bats living in Beit Guvrin focus on only one or two fruit trees every night.

Implementing algorithms that can simultaneously track multiple objects is essential to unlock many applications, from autonomous driving to advanced public surveillance. However, it is difficult for computers to discriminate between detected objects based on their appearance. Now, researchers at the Gwangju Institute of Science and Technology (GIST) adapted deep learning techniques in a multi-object tracking framework, overcoming short-term occlusion and achieving remarkable performance without sacrificing computational speed.

The struggle to get your child to go to sleep and stay asleep is something most parents can relate to. Once the bedtime battle is over and the kids have finally nodded off, many parents tune out as well. But University of South Australia researcher Professor Kurt Lushington is calling for parents to check on their small snoozers before switching off.

The carbon-hydrogen bonds in alkanes--particularly those at the ends of the molecules, where each carbon has three hydrogen atoms bound to it--are very hard to "crack" if you want to replace the hydrogen atoms with other atoms. Methane (CH(4)) and ethane (CH(3)CH(3)) are made up, exclusively, of such tightly bound hydrogen atoms. In the journal Angewandte Chemie, a team of researchers has now described how they break these bonds while forming new carbon-nitrogen bonds (amidation).
