The Lancet: Many countries falling behind on global commitments to tackling premature deaths from chronic diseases, such as diabetes, lung cancer and heart disease
When the disks of gas and dust that surround young stars are misaligned, a phenomenon predicted by models - known as "disk tearing" - does appear to occur, according to a new observational study of a young triple-star system located in the constellation of Orion.
The potential of green infrastructure in mitigating flood impacts: Focused on the mobility of low income and minority comunities
Around the world, the risk of dying prematurely from preventable and largely treatable chronic diseases such as stroke, heart disease, and stomach cancer has declined steadily over the past decade, but death rates from other chronic diseases such as diabetes, lung cancer, colon cancer, and liver cancer are declining too slowly or worsening in many countries.
Timing of tracheostomy for patients with COVID-19 in ICU
This research advances national methods for assessing flood vulnerability and prioritizing transportation improvement investments, to ensure that no community is left stranded when the next flood occurs.
Tiny biological package gets drug right to the 'heart' of transplant rejection
The timing of performing tracheostomies, which are aerosol-generating procedures that may cause increased risk of COVID-19 transmission to health care workers, is examined in this Viewpoint.
To make a better sensor, just add noise
For patients who receive a heart transplant in the near future, the old adage, 'Good things come in small packages,' may become words to live by. In a recent study, researchers at Johns Hopkins Medicine and the National Cancer Institute (NCI) demonstrated in mice that they can easily deliver a promising anti-rejection drug directly to the area surrounding a grafted heart by packaging it within a...
True size of prehistoric mega-shark finally revealed
Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now Penn State researchers have added a small amount of background noise to enhance very weak signals in a light source too dim to sense.
Tryptophan supports guts health on trouts under stress, says a RUDN biologist
A new study led by the University of Bristol and Swansea University has revealed the size of the legendary giant shark Megalodon, including fins that are as large as an adult human.
UCalgary researchers discover how to capture images of cells at work inside our lungs
A biologist from RUDN University found the most beneficial concentration of tryptophan for rainbow trout. When added to the diet of the fish, this amino acid supports the immune system and reduces the oxidative stress in the intestinal tract caused by the overpopulation of fish farms. The results of the study were published in the Aquaculture magazine.
Unmanned aerial vehicles help wheat breeders
University of Calgary scientists have discovered how to capture "live" images of immune cells inside the lungs. The group at the Cumming School of Medicine is the first in the world to find a way to record, in real time, how the immune system battles bacteria impacting the alveoli, or air sacs, in the lungs of mice. The discovery has already provided new insights about the immune systems'...
Wearable, portable invention offers options for treating antibiotic-resistant infections
Usually, breeders pick the best wheat lines by hand, but unmanned aerial vehicles that record certain measures of plant health can help breeders select wheat lines more efficiently.
Weight gainers more likely to underestimate their true body size
About 6 million people in the United States are affected by chronic wounds. Now, a team of innovators from Purdue University has developed a wearable solution that allows a patient to receive treatment without leaving home.
When doing good boosts health, well-being
People with obesity who gain weight have a tendency to perceive their own body size as smaller than it actually is compared to those who maintain a stable weight, according to new research following more than 2,000 people with obesity from the Swedish Obese Subjects (SOS) study over 10 years. The study is being presented at The European and International Congress on Obesity (ECOICO 2020)
Who should get the COVID-19 vaccine first?
Performing acts of kindness and helping other people can be good for people's health and well-being, according to research published by the American Psychological Association. But not all good-hearted behavior is equally beneficial to the giver. The strength of the link depends on many factors, including the type of kindness, the definition of well-being, and the giver's age, gender and other...
Wool-like material can remember and change shape
Nineteen global health experts from around the world have proposed a new, three-phase plan for vaccine distribution -- called the Fair Priority Model -- which aims to reduce premature deaths and other irreversible health consequences from COVID-19.
Exclusive: Brazil Amazon fires likely worst in 10 years, August data incomplete, gov't researcher says
SEAS researchers have developed a biocompatible material that can be 3D printed into any shape and pre-programmed with reversible shape memory. The material is made using keratin, a fibrous protein found in hair, nails and shells, extracted from leftover Agora wool used in textile manufacturing. It could be used in anything from self-fitting bras to actuating textiles for medical therapeutics and...
Researchers identify five types of cat owner
The official August data on the number of fires in Brazil's Amazon needs to be corrected and will likely show an increase over last year, meaning that blazes surged to a decade high, a scientist responsible for the figures told Reuters on Wednesday. Brazilian media has reported that fires in Brazil's section of the Amazon rainforest fell by 5% in August, citing data currently on the website of...

NASA just fired up the most powerful rocket booster ever built — a key part of its Space Launch System to return humans to the moon
Saskatchewan's biggest cities have been steadily adding solar power, but smaller communities like Lumsden are doing it,...
Physicists nudge atoms within less than a trillionth of a second
NASA hopes to fly the full Space Launch System in 2021, then send astronauts to the moon in 2024 as part of its Artemis...
Retest for COVID-19 4-plus weeks after symptoms first appear to curb infection risk, say researchers
Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The extremely sharp needle of their unique ultrafast microscope serves as the technical basis: It carefully scans molecules, similar to a record player. Physicists at the University...

Exposure to workplace sexual harassment linked to an increased risk of suicidal behavior
People who've had COVID-19 should be swab tested again four or more weeks after symptoms first appear to minimize the risk of onward infection, suggests a large population-based study in one of Italy's former coronavirus hotspots.
