Caltech researchers and collaborators have discovered how the bacteria Escherichia coli evolutionarily repurposed cellular machinery into a kind of navigation system to control movement through its environment. The study was led by researchers in the laboratory of Grant Jensen, professor of biophysics and biology and Howard Hughes Medical Institute Investigator. A paper describing the research...
New research begins to reveal how disrupted sleep leads to the fatty arterial plaque buildup known as atherosclerosis that can result in deadly heart disease. “We’ve discovered that fragmented sleep is associated with a unique pathway—chronic circulating inflammation throughout the blood stream—which, in turn, is linked to higher amounts of plaques in coronary arteries,” says...
Collaborative research between CHOP and CDC stresses importance of proper assessments at initial health care visit CHILDREN’S HOSPITAL OF PHILADELPHIA Philadelphia, June 4, 2020 – Head injuries that lead to concussions can happen at any age, and children impacted by concussions have different needs and recovery patterns. In a new study, researchers at Children’s Hospital...
by Buck Institute for Research on Aging Each of the analyzed fly strains arranged by response to dietary restriction. The overlapping bars show the increase or decrease in lifespan (grey bars) or healthspan (purple bars) when that fly strain underwent dietary restriction. Most strains show positive responses, but a number of strains show negative responses...
New research reveals environmental pollutant in drinking water is more dangerous than previously understood. Vanderbilt researchers have discovered that perchlorate, an environmental pollutant found in many sources of drinking water in the U.S., inhibits the uptake of iodide, an essential component of thyroid hormones, in a more pronounced and fundamental way than commonly considered. This...
The study primarily includes industrial workers and employees in jobs with a lot of physical activity, such as nurses, cleaners and people in service professions who are required to stand a lot. Moving more and sitting less has been the ongoing mantra, but this study comes to some different conclusions. “Regular physical activity is still...
COLUMBUS, Ohio – New research suggests mindfulness training may help multiple sclerosis patients in two very different ways: regulating negative emotions and improving processing speed. People with MS who underwent the four-week mindfulness training not only improved more compared to those who did nothing – they also improved compared to those who tried another treatment,...
“Regular endurance training and good fitness seem to protect against serious cardiovascular events and early mortality for people diagnosed with atrial fibrillation,” says exercise physiologist Lars Elnan Garnvik. Garnvik recently completed his doctorate at the Norwegian University of Science and Technology. His latest article was recently published in the prestigious European Heart Journal. Garnvik and...
by Tracey Regan, New Jersey Institute of Technology A team of NJIT physicists has developed a novel test swab that can be 3-D printed using inexpensive, widely available materials and speedily assembled in a range of fabrication settings. To augment the nation’s testing capabilities, the inventors are making the swab’s design publicly available to large...
by Laura Bailey, University of Michigan People with anterior cruciate ligament injuries can lose up to 40% of the muscle strength in the affected leg––with muscle atrophy remaining a big problem even after ACL reconstruction and physical therapy. Now, a new University of Michigan study challenges conventional wisdom about which exercises are most beneficial during...
