Screening is underway to find a patient for the world's first bladder transplant in humans. 

If a vaccine requires cold storage for shipping, many areas where infrastructure doesn't hold up are unable to receive them. A possible solution to this problem is a mobile vaccine printer that could produce hundreds of vaccine doses in a day.

The printer produces patches with hundreds of microneedles containing the vaccine. The patches can be attached to the skin, allowing the vaccine to dissolve without the need for a traditional injection. Once printed, the vaccine patches can be stored for months at room temperature.

In their paper, the scientists used the printer to produce thermostable Covid-19 RNA vaccines that could induce a comparable immune response to that generated by injected RNA vaccines, in mice.

New results show that the number of reported cancer cases in the National Cancer Database during the COVID-19 pandemic declined by 14.4 percen, which means over 200,000 cancer cases were not diagnosed and/or treated.

The reasons were unclear, perhaps concern about catching COVID-19 or being symptomatic but not wanting to go to the doctor because of media claims about those unable to get care for SARS-CoV-2. The results are more obvious; a lot of people are at greater risk. 

New research shows that dairy products have made life easier for thousands of years. Even in places that are a challenge for anyone, like the Tibetan Plateau - the “roof of the world.”

Genetic engineering due to natural selection at several genomic loci certainly made early Tibetans better able to survive high elevations, but those did nothing for calorie requirements. A new study finds that dairy made it possible. Ancient proteins from the dental calculus of 40 human individuals from 15 sites across the interior plateau show that dairying was introduced onto the hinterland plateau by at least 3,500 years ago.

Bud Light may create a marketing campaign to try and increase its brand but when it comes to pricing, experimentation isn't needed. If you want the most sales, target people who shop prices.

It is certainly true that if you have a product during a fad wave, you can charge more. Or, if supplies of a product are scarce, prices will be higher. Yet limited supply means limited revenue. The big money is instead in those who are price shoppers. 

To make solar power viable, there need to be gigantic installations in remote locations. Then there need to be new power lines equivalent to every paved road in America. Then the grid needs to be modernized with battery storage.

None of that is happening any time soon but what may spur at least grid improvements is the reliance on natural gas. Though alternative energy gets mandates and subsidies conventional fuel supplies 80 percent of American energy, but natural gas needs energy to get from place to place. While most of that is still, fittingly, supplied by natural gas, in places where it is supplied by electricity, or even less reliable solar electricity, pipelines are far more subject to outages.
