About The Study: The findings of this study suggest that childhood survivors of acute respiratory distress syndrome (ARDS) are at high risk of readmission in the first two months after discharge. Future studies should evaluate whether post-discharge interventions (e.g., telephonic contact, follow-up clinics, and home health care) may help reduce the readmission burden.  Authors: Garrett Keim, M.D., of Children’s Hospital of Philadelphia, is the corresponding author.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/ (doi:10.1001/jamanetworkopen.2023.30774) Editor’s ...

The zebrafish brain, though simpler than its human counterpart, is a complex network of neurons that engage in a ceaseless dance of electrical activity. What if this neural ballet could reveal the secrets of how brains, including our own, control movement? A zebrafish study led by researchers at the Champalimaud Foundation offers a new lens through which to view the activity of neural populations, and to understand how the brain orchestrates motion. Why we have a brain “The brain’s primary function is movement”, explains Claudia Feierstein, lead author of the study ...

“We engineered E. coli bacteria, the most widely studied microbe, to generate electricity,” says Professor Ardemis Boghossian at EPFL. “Though there are exotic microbes that naturally produce electricity, they can only do so in the presence of specific chemicals. E. coli can grow on a wide range of sources, which allowed us to produce electricity in a wide range of environments, including from waste water.” In a paper published in the journal Joule, Boghossian’s team report a groundbreaking achievement in bioelectronics, advancing the capabilities of common E. coli bacteria to generate ...

The ability to visualize faces, objects, landscapes, or even scenes from the past exists on a spectrum. While some can picture the layout of a city in minute detail and mentally walk through it, street by street, others have a perfectly blank internal cinema. In this case, we speak of aphantasia—the inability to voluntarily produce the visual mental image corresponding to an idea. People whose aphantasia is congenital—i.e., not due to a stroke, brain injury, or psychiatric illness—become aware of their peculiarity reasonably ...

As of today, climate models face the challenge of providing the high-resolution predictions -  with quantified uncertainties - needed by a growing number of adaptation planners, from local decision-makers to the private sector, who require detailed assessments of the climate risks they may face locally.   This calls for a step change in the accuracy and usability of climate predictions that, according to the authors of the paper “Harnessing AI and computing to advance climate modelling and prediction”, can ...

A paper published in the journal Monthly Notices of the Royal Astronomical Society hints at the existence of several black holes in the Hyades cluster — the closest open cluster to our solar system — which would make them the closest black holes to Earth ever detected.  The study results from a collaboration between a group of scientists led by Stefano Torniamenti, from the University of Padua (Italy), with the significant participation of with Mark Gieles, ICREA professor at the Faculty of Physics, the ...

Nanoparticles are tiny structures up to 100 nanometers in size. They are characterized by different physical and chemical properties and biological activity than their larger material counterparts. - When the starting material on a micro-scale with a specific surface area is broken down to nano size, i.e. into smaller particles, its surface area will increase many times. And it is the ratio of surface to volume that results in the unique properties of nanoparticles, explains Prof. Mahendra Rai from Sant Gadge Baba Amravati University in India. Nanoparticles can be mainly ...

Close relatives of people with metabolic-associated fatty liver disease have a higher risk of developing liver cancer and dying from liver-related diseases, according to a national study from Karolinska Institutet in Sweden published in The Journal of Hepatology. This means that family members could also benefit from the lifestyle advice that is currently only given to patients, the researchers conclude. People with metabolic-associated fatty liver disease (MASLD, formerly known as NAFLD – see fact box) have an elevated risk of developing and dying from liver cancer. MASLD is now the main reason why the number of people developing liver cancer ...

A new study has found that air pollution is preventing pollinators finding flowers because it degrades the scent. A research team comprising the UK Centre for Ecology & Hydrology (UKCEH) and the Universities of Birmingham, Reading, Surrey and Southern Queensland, found that ozone substantially changes the size and scent of floral odour plumes given off by flowers, and that it reduced honeybees' ability to recognise odours by up to 90% from just a few metres away. Ground-level ozone typically forms when nitrogen oxide emissions from vehicles and industrial processes react with volatile organic compounds emitted from vegetation ...

LAWRENCE — Many of us know all too well the addictive nature of many foods marketed in the United States — most call it “junk food.” In fact, this kind of salty, sweet and high-fat fare makes up the lion’s share of what’s marketed to Americans. Researchers employ a more scholarly term for food items featuring purposely tempting combinations of salts, fats and sugars: They’re “hyperpalatable.” Now, an investigator at the University of Kansas has conducted research showing food brands owned by tobacco ...

Computer scientists and mathematicians working in complex systems at the University of Sydney and the Max Planck Institute for Mathematics in the Sciences in Germany have developed new methods to describe what many of us take for granted – how easy, or hard, it can be to fall in and out of sync. Synchronised phenomena are all around us, whether it is human clapping and dancing, or the way fireflies flash, or how our neurons and heart cells interact. However, it is something not fully understood in engineering and science. Associate Professor Joseph Lizier, expert in complex systems at the University of Sydney, said: “We know ...

Developing new drugs is paramount in discovering innovative treatments and preventing diseases. This is vital not only for advancing medicine but also for the overall health and well-being of humanity. Yet, even when drugs demonstrate safety and efficacy in cell and animal models, they frequently encounter hurdles in clinical trials on human.   A single setback for a drug during clinical trials, which involves diverse population groups, can result in significant economic losses. To address this, it is imperative to understand why certain drugs, despite passing the preclinical stages, falter during clinical ...

In the summer of 1931, an unprecedented calamity unfolded along the Yangtze River basin in eastern China - the 1931 Yangtze River flood, known as one of history's deadliest natural disasters. This cataclysmic event submerged a staggering 180,000 km2, affected 25 million lives, and tragically claimed over 2 million lives. Despite its immense societal impact, the origins of this monumental flood have remained largely unexplored, a challenge compounded by the scarcity of historical records and pre-1950s meteorological data in China. Recent access to crucial historical datasets has, however, unlocked the ability to investigate the 1931 Yangtze River flood. A recent study published ...

As a result of the climate crisis, future forests may become unrecognizable. Trees that currently make up European woods may no longer be seen — or they may have moved several hundred meters uphill. Scientists writing in Frontiers in Forests and Global Change have mapped the forests of five vulnerable mountain areas in Italy and modelled the future of these fragile ecosystems. “If I imagine my daughter walking with me as an old man, in our mountain forests, I can imagine that we can see the initial stage of a profound ...

Children have loved Disney princesses since Snow White and the Seven Dwarfs premiered in theaters in 1937. While this adoration continues to grow in terms of princess movie ratings, some parents may wonder what effects these idealized images of young women might have on how their children feel about and express themselves.  According to new research from the University of California, Davis, a favorite princess improved — but did not harm — young children’s ...

The observatory has been used to document the transport of Saharan dust particles across the Atlantic Ocean to the Caribbean, creating the longest-running dust data set in existence. Scientists from many different disciplines use the data to understand how dust particles impact everything from coral reef health to cloud formation and tropical storms. Through a grant from the National Science Foundation (NSF), the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science recently completed a major upgrade to its Barbados Atmospheric Chemistry Observatory (BACO), expanding its capability ...

The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane — a greenhouse gas — into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays. Methane is also released when organics-rich permafrost thaws as the result of heat carried by the spreading water. A study linking Arctic beavers to an increase in the release of methane was ...

Australia’s employment laws and regulations must be updated to reflect the changing nature of work, with many people continuing to work from home long after the COVID-19 pandemic. That’s according to University of South Australia Associate Professor of Organisational Behaviour Dr Ruchi Sinha who says labour laws and protections should be updated to clarify issues related to work hours, overtime, and breaks in a remote work context, now that almost half of all employees are working from home at least once a week. The Australian Institute of Health and Welfare ...
