Twenty scientists from 14 countries warn of a hidden "pandemic within the pandemic" in two current publications. On the one hand, physical activity levels have gone down significantly, on the other hand, psychological well-being has suffered. "Governments and those responsible for health systems should take our findings seriously," emphasizes the author team, headed by Dr Jan Wilke from the Institute for Sport Sciences at Goethe University Frankfurt.
Ant workers that are infected with a tapeworm live much longer than their uninfected nest-mates. Parasitic infections are usually harmful to their hosts, but there are some exceptions. According to the results of a multi-year scientific study, ants of the species Temnothorax nylanderi show exceptionally high survival rates when infected with a tapeworm. "The lifespan of the infected ants is significantly prolonged.
A new discovery by University of Guelph researchers may ultimately help in devising new therapies and improving quality of life for people with Parkinson's disease.
By showing how entangled proteins in brain cells enable the neurodegenerative disease to spread, the researchers hope their findings will lead to drugs that halt its progression, said PhD candidate Morgan Stykel, first author of a paper published this month in Cell Reports.
In the largest genetic analysis of depression to date, Veterans Affairs researchers identified many new gene variants that increase the risk for depression. The groundbreaking study helps researchers better understand the biological basis of depression and could lead to better drug treatments.
URBANA, Ill. - As the owner of a human body, you're carrying trillions of microbes with you everywhere you go. These microscopic organisms aren't just hitching a ride; many of them perform essential chemical reactions that regulate everything from our digestion to our immune system to our moods.
EUGENE, ORE. -- May 27, 2021 -- Climate skeptics who aren't persuaded by the existing evidence from climate change are unlikely to change their minds for many years, according to a newly published quantitative study by a University of Oregon environmental economist
While earlier research has mostly looked into factors such as fear, perceived risk, age and political views to determine what makes individuals and societies more or less willing to drastically change their lifestyle and support government-imposed strict restrictions, in order to mitigate the spread of the COVID-19 pandemic, psychologists at the University of Zurich Charlotte Kukowski, Katharina Bernecker and Veronika Brandstätter took a different perspective.
AUSTIN, Texas -- In the perpetual arms races between bacteria and human-made antibiotics, there is a new tool to give human medicine the edge, in part by revealing bacterial weaknesses and potentially by leading to more targeted or new treatments for bacterial infections.
A research team led by scientists at The University of Texas at Austin has developed chemical probes to help identify an enzyme, produced by some types of E. coli and pneumococcal bacteria, known to break down several common types of antibiotics, making these bacteria dangerously resistant to treatment.
Study Exploring Optimization of Duplex Velocity Criteria for Diagnosis of Internal Carotid Artery (ICA) Stenosis Published Online
Online first in Vascular Medicine, researchers from the Intersocietal Accreditation Commission (IAC) Vascular Testing division report findings of their multi-centered study of duplex ultrasound for diagnosis of internal carotid artery (ICA) stenosis. 1
Aging published "Potential reversal of epigenetic age using a diet and lifestyle intervention: a pilot randomized clinical trial" which reported on a randomized controlled clinical trial conducted among 43 healthy adult males between the ages of 50-72. The 8-week treatment program included diet, sleep, exercise and relaxation guidance, and supplemental probiotics and phytonutrients.
More than 500,000 people have died from COVID-19 in Latin America and the Caribbean, demonstrating the health and economic inequalities throughout the region. A new article analyzes seven books* that discuss these inequalities, including questions of who gets health care and what interdependent roles societies, social movements, and governments play. To end inequality in the region, the author calls for a universal approach to health care.
Although it is not spread through human contact, Francisella tularensis is one of the most infectious pathogenic bacteria known to science--so virulent, in fact, that it is considered a serious potential bioterrorist threat. It is thought that humans can contract respiratory tularemia, or rabbit fever--a rare and deadly disease--by inhaling as few as 10 airborne organisms.
On scales too small for our eyes to see, the business of life happens through the making of proteins, which impart to our cells both structure and function. Cellular proteins get their marching orders from genetic instructions encoded in DNA, whose sequences are first copied and made into RNA in a multi-step process called transcription.
SAN ANTONIO (May 27, 2021) — One-fifth of babies who inherit a genetic variant located on chromosome 16 will develop autism spectrum disorder (ASD) by age 3. The variant is called 16p11.2 deletion.
May 27, 2021 - Patients undergoing total hip arthroplasty (THA) show significant reduction in pain and other symptoms and improvement in walking gait biomechanics. However, those improvements do not lead to increased daily physical activity levels, reports a study in The Journal of Bone & Joint Surgery.
