Droplets Loaded With Coronaviruses Last Far Longer Than Previously Thought

Tiny droplets loaded with viruses disappear more slowly after exhalation than previous models suggested. Experiments and simulations by TU Wien (Vienna) can now explain this. It is easier to get infected in winter than in summer — this is true for the Corona pandemic, for influenza, and for other viral diseases. Relative humidity plays an […]

Personalized Advice: How To Prevent and Treat High Blood Pressure With Exercise

The first personalized advice on the most effective exercise to lower blood pressure was published in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC). The ESC consensus document recommends specific activities according to an individual’s current blood pressure level. One in four heart attacks are caused by high blood […]

FDA Panel Voted 16–2 To Deny Authorization of Pfizer’s COVID Vaccine “Booster” Shot to the General Public

The key scientific advisory council of the Food and Drug Administration has voted to deny authorization of a “booster” shot of Pfizer’s mRNA vaccine to the general public – a move that will likely disappoint some public health experts pushing for a third dose to help slow the spread of COVID-19. In a 16-2 vote on […]

Layered Graphene with a Twist Displays Unique Quantum Confinement Effects in 2-D

Scientists studying two different configurations of bilayer graphene—the two-dimensional (2-D), atom-thin form of carbon—have detected electronic and optical interlayer resonances. In these resonant states, electrons bounce back and forth between the two atomic planes in the 2-D interface at the same frequency. By characterizing these states, they found that twisting one of the graphene layers by 30 […]

More Than 1 in 10 COVID-19 Patients Were Infected After Hospital Admission in First Pandemic Wave

More than one in ten COVID-19 patients in 314 UK hospitals caught the infection in a hospital during the first pandemic wave say researchers conducting the world’s largest study of severe COVID-19. The research into hospital-acquired infections (HAIs) was led by Dr. Jonathan Read from Lancaster University with colleagues from other UK universities including the Universities of […]

Reproductive Specialist: Link Between Menstrual Changes After COVID-19 Vaccination Should Be Investigated

Reported changes short lived, but research into this possible adverse reaction remains critical to the success of the vaccination program. Some women say their periods change after getting a covid-19 vaccination. In The BMJ today (September 15, 2021), Dr. Victoria Male, a reproductive specialist at Imperial College London, says a link between menstrual changes after covid-19 vaccination is […]

Promising New Stem Cell Treatment for MRSA Superbug Infections

A study released in STEM CELLS Translational Medicine (SCTM), by researchers at the Baker Institute for Animal Health, part of Cornell University’s College of Veterinary Medicine, Ithaca, N.Y., details in a relevant ex vivo model how treating wounds with the secretion of a type of stem cell called mesenchymal stromal cell (MSC) effectively reduced methicillin-resistant Staphylococcus aureus – better known […]
