The bubbles created by intense focused lasers in this experiment were ten times smaller and contained water vapour at a pressure around a hundred thousand times higher than orginary bubbles in water. They expand at supersonic speed, pushing a shockwave in front. Researchers led by University of Göttingen with Deutsches Elektronen-Synchroton (DESY) and European X-Ray Free-Electron Laser (European XFEL), used holographic flash imaging and X-ray laser pulses to make images. Research appears in Nature Communications.

Preliminary results from a study of more than 700,000 patients with traumatic brain injury (TBI) show that those with a sleep disorder had an increased risk of developing dementia.

A recent study of teens and young adults found that several factors related to sleep timing and sleep duration are associated with an increased risk of cannabis use and binge drinking of alcohol during the following year.

In a recent study, University of Rochester and University of Michigan political scientist examined two common policy interventions--economic and psychological--designed to counter the growing radicalization in the US. They found that improving economic conditions reduces both radicalization efforts and dissent. However, trying to render people psychologically less susceptible to radicalization can backfire and instead increase radical leaders' efforts to influence and radicalize more followers.

Cities located in metropolitan areas of this Brazilian state score better according to an index that measures the existence of public policies designed to adjust critical sectors to the impacts of climate change.

Researchers have shown that even after lung tissue has been damaged, it may be possible to reverse fibrosis and promote tissue repair through treatment with microgel-coated mesenchymal stromal cells.

Despite updates from the World Health Organization, the U.S. Centers for Disease Control and Prevention (CDC) and the Public Health Agency of Canada that the virus can be transmitted by short- and long-range aerosols, Canada's public health guidance has not been adequately updated to address this mode of transmission, argue authors of a commentary published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/content/early/2021/06/08/cmaj.210830.

Millions of adults could lower the chance that they'll ever need a drug to treat dementia including Alzheimer's disease, if they work with their primary care providers and use the power of prevention to keep their brains healthy. A recent review by a national panel of experts summarizes the evidence behind steps providers and patients can take to identify and change modifiable risk factors.

The June issue of CHEST includes 95 articles including original research on racial disparities in asthma and COPD, lung cancer among gender minority individuals, and more.

A study conducted by researchers at the Ludwig Center at Harvard has demonstrated how a drug screening method known as dynamic BH3 profiling can be used to quickly identify potentially effective combinations of existing drugs for personalized cancer therapy.

High-value chemicals used in biofuels and pharmaceuticals can be made from bacteria by switching their chemistry to produce novel products. Researchers from the University of Warwick have found a way to drastically cut the cost of turning on these switches.

A new study from the University of Minnesota published in The Journal of the American Dental Association compared the self-identified oral health needs and access to dental care among youth who have and have not experienced foster care.

Researchers have developed a novel multi-well, continuous-flow microfluidic device that may help scientists and pharmaceutical companies more effectively study drug compounds and their crystalline shapes and structures, which are key components for drug stability.

Mining involves moving a lot of rock, so some mess is expected. However, mining operations can continue to affect ecosystems long after activity has ended. Heavy metals and corrosive substances leach into the environment, preventing wildlife and vegetation from returning to the area.

Since the end of the long-running conflict in Colombia, large areas of forest have been rapidly converted to agricultural uses, suggesting the peace agreement presents a threat to conservation the country's rainforest.

Last year, Anupam Mazumdar, a physicist from the University of Groningen, proposed an experiment that could conclusively prove whether gravity is a quantum phenomenon. In a new article, published on June 4, 2021 in Physical Review Research, he describes how two types of noise could be reduced and suggests that quantum interference could be applied in the production of a sensitive instrument that could detect movements of objects ranging from butterflies to burglars and black holes.

Many voice actors use a variety of speech vocalizations and patterns to create unique and memorable characters. How they create those amazing voices could help speech pathologists better understand the muscles involved for creating words and sounds. During the 180th ASA Meeting, Colette Feehan from Indiana University will talk about how voice actor performances can lead to better understanding about the speech muscles under our control. The session, "Articulatory and acoustic phonetics of voice actors," will take place Tuesday, June 8, 2021.

In a study of healthy volunteers, National Institutes of Health researchers have mapped out the brain activity that flows when we learn a new skill, such as playing a new song on the piano, and discovered why taking short breaks from practice is a key to learning.

In a new study published in the journal Genes & Development, Shihoko Kojima and her team has identified a novel gene, Per2AS, that controls the sleep/wake cycle in mice. Per2AS appears to be a new type of gene, known as a non-coding gene. Unlike most other genes, Per2AS is not translated from RNA into a subsequent protein, thus making its function unclear until now.

"The manuscript offers a unique and timely perspective on plant diseases, particularly in the context of the COVID-19 pandemic," said David Schmale, a co-author on the paper and a professor in the Virginia Tech School of Plant and Environmental Sciences in the College of Agriculture and Life Sciences.
