Cells breathe, to an extent, exchanging gases, taking in energy sources from the environment and processing it. Now, researchers from Tohoku University in Japan have shone a light on the process in a new way.

The Society for Cardiovascular Angiography and Interventions (SCAI) has released an expert consensus statement providing cardiologists, cath lab directors, and hospital leadership guidance for contemporary cath lab standards. The document, "SCAI Expert Consensus Update on Best Practices in the Cardiac Catheterization Laboratory" will be presented today at the SCAI 2021 Virtual Scientific Sessions with simultaneous publication in Catheterization & Cardiovascular Interventions.

For more than a decade, ecologists have been warning of a downward trend in bumble bee populations across North America, with habitat destruction a primary culprit in those losses. While efforts to preserve wild bees in the Midwest often focus on restoring native flowers to prairies, a new Illinois-based study finds evidence of a steady decline in the availability of springtime flowers in wooded landscapes.

The formation of dead Lithium during stripping process is investigated in the whole course from the electron transfer, the conversion of Li0 to Li+ and the diffusion of Li+.

Age may influence an a human egg cell's ability to process gene products essential for the last steps of its development. The final maturation stage is critical for reproduction because it provides the material early embryos need to develop normally and survive. The researchers also found that abnormal BMI also impacted oocyte development, but through different root mechanisms compared to the fertility decline caused by age.

Scientists have identified the specific structural element of von Willebrand Factor that allows it to bind with platelets and initiate blood clotting. The team says that the specific unit, which they call the discontinuous autoinhibitory module, or AIM, is a prime site for new drug development. The work is described in an article published last week in Nature Communications, "Activation of von Willebrand factor via mechanical unfolding of its discontinuous autoinhibitory module."

A national, University at Buffalo-led study on genes in pediatric cardiomyopathy demonstrates strong evidence for routine genetic screening in children with the disease.

Pseudomonas aeruginosa biofilms have been modified to capture microplastics from water, trapping them for release and recycle.

Researchers found that a silica surface such as sand has little effect on slowing down the movement of the plastics, but that natural organic matter resulting from decomposition of plant and animal remains can either temporarily or permanently trap the nanoscale plastic particles, depending on the type of plastics. The work could lead to the development of better ways to filter out and clean up pervasive plastics from the environment.

CHARGE syndrome is a rare genetic disorder affecting about 1 in 10,000 newborns. It can lead to neurological and behavioural disorders for which no treatment is currently available. Dr. Kessen Patten and his team, from the Institut national de la recherche scientifique (INRS) have just discovered a compound that could alleviate these symptoms. The results of their research were published in the journal EMBO Reports.

Whether you hanker for a hard hit of caffeine or favour the frothiness of a milky cappuccino, your regular coffee order could be telling you more about your cardio health than you think.In a world first study of 390,435 people, University of South Australia researchers found causal genetic evidence that cardio health - as reflected in blood pressure and heart rate - influences coffee consumption.

Hot flashes are a hallmark of the menopause transition. Yet, they don't strike with the same frequency or severity for all women. A new study suggests that some of the same genetic factors that affect a woman's reproductive life cycle may also help predict her likelihood of having bothersome hot flashes. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

Parents of teens who went through puberty early may be more lenient when it comes to letting them consume alcohol, according to a new Penn State study. But the researchers said that even if adolescents appear more mature, drinking alcohol is still not safe for them.

A new GeneSight Mental Health Monitor national survey finds 83 percent of those diagnosed with depression say life would be easier if others could understand what they're going through. Yet, most reported they were more likely to hear statements that demonstrate a lack of understanding and support for what they are experiencing.

A new study shows growing evidence that Pennsylvania's 500 ft. unconventional natural gas (UNG) well setback distance may not be protective against routine exposures to toxic substances such as benzene, hydrogen sulfide, carbon disulfide and PM2.5. This is the first study to assess the effectiveness of setback regulations for UNG development, and the findings suggest that protectiveness of setback policies also depends upon opportunities for exemptions from these siting restrictions.

A new study examined why early developing 14-year-old adolescents are more likely to drink alcohol compared to those whose pubertal development is on-time or late. The findings show these adolescents are more likely to have peers who drink alcohol and are also given greater permission to drink by their parents.

Decision making problems involving multiple agents are often solved using policy iteration, in which a given policy generates a better one. However, the required amount of computation is often prohibitively large. In a new study, a computer scientist takes things to the next level with an approach where decisions are made sequentially and the computations grow only linearly with agents, drastically reducing its complexity and opening doors to a revolution in studying multiagent systems.

Researchers at the National Food Institute, Technical University of Denmark, have generated a lactic acid bacterium that efficiently secretes a food-grade preservative when grown on dairy waste.

Over recent decades, volunteer environmental monitoring (often called "citizen science") has exploded in popularity, aided both by smartphones and rapid gains in computing power that make the analysis of large data sets far easier.

In a first-of-its-kind study, scientists from the UK and Germany used drones to provide a synchronised bird's eye view of what seabirds see and how their behaviour changes depending on the movement of tidal flows beneath them.
