Scientists have uncovered changes inside taste buds that may help explain why some people struggle to taste food more than a year after recovering from COVID-19. The findings point to disruptions in the molecular signals responsible for detecting certain flavors, along with physical abnormalities in the structure of taste buds. The study, published in Chemical Senses, offers the first direct biological evidence connecting persistent taste problems reported by patients to measurable changes within their taste cells.

The popularity of the giant-impact hypothesis can be attributed to the multiple lines of evidence supporting the impact scenario.

Much like sushi or political humor, badly needed donor organs tend to have a pretty short shelf life. By current estimates, vital organs like a heart or a lung need to be transplanted into their waiting human recipient within six hours or less, while the most hardy of these organs, the kidney, can only remain viable for up to 36 hours before surgery. These unforgiving expirations dates have helped keep over 100,000 Americans (and counting) stuck on the waiting list for a new organ—but surgeons and medical researchers at the University of Minnesota have just reported a breakthrough that might finally get this line moving. A university team, co-led by transplant surgeon Erik Finger, says it has effectively kept pig kidneys in cold storage for months, and in one case over a year, managing to gently thaw, test, and successfully transplant these warmed-over organs into test pig recipients. The research, published as a pre-print with bioRxiv while it awaits peer review, confirmed that the once-frozen organs had both regained their color and helped the test pigs produce urine: critical signs that restored blood flow and organ function had been achieved.
