Styrofoam is very lightweight, unless you compare it to the new micro-lattice cellular material developed by a team of researchers from UC Irvine, HRL Laboratories and Caltech. Compared to Styrofoam, this new material is 100 times less dense and is said to be the lightest material in the world. In fact, it is so lightweight […]
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 […]
Researcher discovers that the underground species has a secret glow. You can learn a lot about animals by simply watching them. But some secrets can only be revealed in the dark … with an ultraviolet flashlight. This happens to be the case for pocket gophers, small rodents that live underground in sandy soil. A new […]
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 […]
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 […]
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 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 […]
The level of public acceptance of evolution in the United States is now solidly above the halfway mark, according to a new study based on a series of national public opinion surveys conducted over the last 35 years. “From 1985 to 2010, there was a statistical dead heat between acceptance and rejection of evolution,” said […]
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 […]
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 […]
