Through the biological fixation of the element nitrogen by the enzyme nitrogenase, organisms gain access to molecular nitrogen (N2) in the Earth's atmosphere, which is essential for building cellular structures. In addition, a vanadium-dependent variant of nitrogenase can reduce the toxic gas carbon monoxide (CO) to hydrocarbons. These reductions of N2 and CO are among the most important processes in industrial chemistry, as they are used to produce both fertilizers and synthetic fuels. However, researchers have not yet been able to decipher the different pathways of the two reactions. Dr.
MINNEAPOLIS/ST.PAUL (06/10/2021) -- New findings from the University of Minnesota Medical School are helping uncover why some people are more likely to be overweight and develop Type 2 diabetes -- and it starts in the womb.
Genova (Italy) 10 June, 2021 - The U-Vip (Unit for Visually Impaired People) research team led by Monica Gori at the IIT- Istituto Italiano di Tecnologia (Italian Institute of Technology) has recently published a study which shows for the first time how children aged from 3 to 5 years old have problems in recognising the emotions of people wearing surgical masks. This collateral effect of the preventive measures linked to the Covid-19 health emergency could influence the correct development of children's capabilities of social interaction.
Because of a phenomenon called gravitational locking, the Moon always faces the Earth from the same side. This proved useful in the early lunar landing missions in the 20th century, as there was always a direct line of sight for uninterrupted radiocommunications between Earth ground stations and equipment on the Moon. However, gravitational locking makes exploring the hidden face of the moon--the far side--much more challenging, because signals cannot be sent directly across the Moon towards Earth.
Plants are constantly exposed to microbes: pathogens that cause disease, commensals that cause no harm or benefit, and mutualists that promote plant growth or help fend off pathogens. For example, most land plants can form positive relationships with arbuscular mycorrhizal fungi to improve nutrient uptake. How plants fight off pathogens without also killing beneficial microbes or wasting energy on commensal microbes is a largely unanswered question.
An exploratory investigation into the behavior of materials with desirable electric properties resulted in the discovery of a structural phase of two-dimensional (2D) materials. The new family of materials are electrides, wherein electrons occupy a space usually reserved for atoms or ions instead of orbiting the nucleus of an atom or ion. The stable, low-energy, tunable materials could have potential applications in nanotechnologies.
Music is a tool that has accompanied our evolutionary journey and provided a sense of comfort and social connection for millennia. New research published today in the American Psychologist provides a neuroscientific understanding of the social connection with a new map of the brain when playing music.
GRAND RAPIDS, Mich. (JUNE 10, 2021) -- Much like a supply truck crossing the countryside, the misfolded proteins that damage neurons in Alzheimer's disease travel the "roads" of the brain, sometimes stopping and sometimes re-routing to avoid roadblocks, reports a study published in Science Advances by researchers at Van Andel Institute and University of Pennsylvania.
Just as the governor announced the start of python hunting season in Florida this month, researchers at the University of Central Florida have published a first- of-its-kind study that shows that near-infrared (NIR) spectrum cameras can help hunters more effectively track down these invasive snakes, especially at night.
Researchers remain perplexed as to what causes dementia and how to treat and reverse the cognitive decline seen in patients. In a first-of-its-kind study, researchers at the Medical University of South Carolina (MUSC) and Beth Israel Deaconess Medical Center (BIDMC), Harvard Medical School discovered that cis P-tau, a toxic, non-degradable version of a healthy brain protein, is an early marker of vascular dementia (VaD) and Alzheimer's disease (AD).
WACO, Texas (June 9, 2021) - Most people listen to music throughout their day and often near bedtime to wind down. But can that actually cause your sleep to suffer? When sleep researcher Michael Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor University, realized he was waking in the middle of the night with a song stuck in his head, he saw an opportunity to study how music -- and particularly stuck songs -- might affect sleep patterns.
June 10, 2021, CLEVELAND: A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimer's disease-like dementia. The findings, published in Alzheimer's Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimer's, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.
Metformin is a widely prescribed blood sugar-lowering drug. It is often used as an early therapy (in combination with diet and lifestyle changes) for type 2 diabetes, which afflicts more than 34 million Americans.
Metformin works by lowering glucose production in the liver, reducing blood sugar levels that, in turn, improve the body's response to insulin. But scientists have also noted that metformin possesses anti-inflammatory properties, though the basis for this activity was not known.
Married men who don't help out around the house tend to bring home bigger paychecks than husbands who play a bigger role on the domestic chores front.
New research from the University of Notre Dame shows that "disagreeable" men in opposite-sex marriages are less helpful with domestic work, allowing them to devote greater resources to their jobs, which results in higher pay.
Have you ever been cut off in traffic by another driver, leaving you still seething miles later? Or been interrupted by a colleague in a meeting, and found yourself replaying the event in your head even after you've left work for the day? Minor rude events like this happen frequently, and you may be surprised by the magnitude of the effects they have on our decision-making and functioning. In fact, recent research co-authored by management professor Trevor Foulk at the University of Maryland's Robert H.
