Scientists at Johns Hopkins Medicine using MRI scans and computer modeling say they have further pinpointed areas of the human brain that regulate efforts to deal with fatigue.
The findings, they say, could advance the development of behavioral and other strategies that increase physical performance in healthy people, and also illuminate the neural mechanisms that contribute to fatigue in people with depression, multiple sclerosis and stroke.

Too many COVID-19 patients get unneeded “just in case” antibiotics
More than half of patients hospitalized with suspected COVID-19 in Michigan during the state’s peak months received antibiotics soon after they arrive, just in case they had a bacterial infection in addition to the virus, a new study shows. But testing soon showed that 96.5% of them only had the coronavirus, which antibiotics don’t affect.
New Device Can Measure Toxic Lead Within Minutes
Rutgers researchers have created a miniature device for measuring trace levels of toxic lead in sediments at the bottom of harbors, rivers and other waterways within minutes – far faster than currently available laboratory-based tests, which take days. The affordable lab-on-a-chip device could also allow municipalities, water companies, universities, K-12 schools, daycares and homeowners to easily and swiftly test their water supplies. The research is published in the IEEE Sensors Journal.

Largest pharmacogenetic clinical trial in cardiology shows potential benefit in individualized approach to anti-platelet therapy
ROCHESTER, Minn. ― Heart patients who undergo percutaneous coronary intervention (PCI) or stent placement― nonsurgical procedures to improve blood flow to the heart ― are typically prescribed anti-platelet therapy to avoid blood clots that can lead to a heart attack or stroke. New research from the international TAILOR-PCI trial, the largest pharmacogenetics clinical trial in cardiology, suggests that genetic testing could potentially be a useful tool to help select antiplatelet medication. Pharmacogenetics is the use of a patient’s genetic makeup in prescribing treatments that are likely to be most successful.
International cardiology trial shows potential benefit of using personalized medicine in blood thinner therapy selection

Polymers Prevent Potentially Hazardous Mist During Dentist Visit
If the mist in a dentist’s office — sent flying into the air by spinning, vibrating tools — contains a virus or some other pathogen, it is a health hazard for dentists and patients. So researchers in Illinois studied the viscoelastic properties of food-grade polymers and discovered that the forces of a vibrating tool or dentist’s drill are no match for them. Not only did a small admixture of polymers completely eliminate aerosolization, but it did so with ease.
Effectiveness of Cloth Masks Depends on Type of Covering
Months into the COVID-19 pandemic, wearing a mask while out in public has become the recommended practice. However, many still question the effectiveness of this. To allay doubts, Padmanabha Prasanna Simha, from the Indian Space Research Organisation, and Prasanna Simha Mohan Rao, from the Sri Jayadeva Institute of Cardiovascular Sciences and Research, experimentally visualized the flow fields of coughs under various common mouth covering scenarios. They present their findings in the journal Physics of Fluids.
Building Mechanical Memory Boards Using Origami
Origami can be used to create mechanical, binary switches, and in Applied Physics Letters, researchers report the fabrication of such a paper device, using the Kresling pattern, that can act as a mechanical switch. By putting several together on a single platform, the investigators built a functioning mechanical memory board. They found that oscillating the platform up and down at a certain speed will cause it to flip, or switch, between its two stable states.

Sanders-Brown Study Leads to Potential for a New Treatment Approach to Alzheimer’s Disease
The paper explains that current therapeutic approaches to the treatment of Alzheimer’s disease focus on the major pathological hallmarks of the disease which are amyloid plaques and neurofibrillary tangles. They are the requirements for a diagnosis of Alzheimer’s disease. However, the authors say there has been an explosion of genetic data suggesting the risk for sporadic Alzheimer’s disease is driven by several other factors including neuroinflammation, membrane turnover and storage, and lipid metabolism.
