The homemade face covering that best contains respiratory droplets like those from COVID-19 is a neck-gaiter-style mask combining a nose piece with an elastic cord wearers can toggle to snug the mask to their face, according to a UW-Madison engineer.
In a cool video posted online this week, UW–Madison mechanical engineering professor Scott Sanders uses a mannequin to illustrate how droplets escape or stay contained inside a variety of masks now being worn.
For covaxin, Bharat Biotech has joined with the National Institute of Virology, which is part of the Indian Council of Medical Research (ICMR). (The company is separately developing COVID-19 vaccine candidates in collaboration with Thomas Jefferson University in Philadelphia and the University of Wisconsin, Madison.)
It should also be noted that the company is simultaneously also engaged in the development of another vaccine called ’Coroflu’ which is being developed in a collaboration with the University of Wisconsin-Madison and vaccine maker FluGen.
The CDC previously awarded more than $10 million to help aid state and local efforts to stem the spread of the disease. Scientists at the University of Wisconsin-Madison have been deeply involved in the search for a vaccine, and hundreds of Wisconsin families are part of a federal study on the role children play in spreading the virus.
New video shows a deep dive into mask protection using a simulated cough test. UW Madison’s Engine Research Center is demonstrating how droplets from a cough travel from inside different styles and materials of masks.
UW-Madison researchers used tiny balls of minerals to deliver protein-making instructions to cells surrounding wounds in diabetic mice, healing the wounds faster than other methods and showing promise for developing better protein-based drugs for a variety of diseases, according to a new study.
Gov. Tony Evers has given the University of Wisconsin System the go-ahead to begin complying with new federal rules that bolster the rights of sexual misconduct defendants and narrow the range of sexual misconduct that colleges must investigate.
Iris Zhou, an 18-year-old from Wuxi in eastern China, has been admitted to the University of Wisconsin-Madison for the coming school year, but the earliest visa appointment she could get when she applied in May was in November.
Most recently, Lewis, who earned his doctorate of education from the University of Wisconsin–Stout, was the higher education director at the Ho-Chunk Nation Education Department where he designed a successful work-based learning internship program and increased the annual college graduation rate by 250 percent.
Quoted: “A mask that is not covering the nose will not stop a person infected with SARS-CoV-2 from contaminating the air in front of them when they exhale. Similarly, a mask covering only the mouth will fail to prevent an uninfected person from inhaling contaminated air. Since it does not take a lot of virus particles to cause infection, a partially worn mask may not be effective enough. This reminds me of when I see people wearing a bicycle helmet without buckling the strap or wearing it so loosely that it doesn’t cover the front of their head. The intention might be there, but there is a higher risk of head injury following an accident if the helmet is unable to do what it is designed to do.”

The UW Health Emergency Department treated a few patients for heat-related illness over the weekend.
