Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study by researchers at the Stanford University School of Medicine.

The researchers also found that elderly mice regained youthful strength after their existing muscle stem cells were subjected to the rejuvenating protein treatment and transplanted back into their bodies.

The proteins, known as Yamanaka factors, are commonly used to transform an adult cell into what are known as induced pluripotent stem cells, or iPS cells. Induced pluripotent stem cells can become nearly any type of cell in the body, regardless of the cell from which they originated. They’ve become important in regenerative medicine and drug discovery.

New research suggests that digestive symptoms, including a loss of appetite and diarrhea, are more common in people with COVID-19 than doctors had thought.

Coronavirus RNA survived for up to 17 days aboard the Diamond Princess cruise ship, living far longer on surfaces than previous research has shown, according to new data published Monday by the Centers for Disease Control and Prevention.

The study examined the Japanese and U.S. government efforts to contain the COVID-19 outbreaks on the Carnival-owned Diamond Princess ship in Japan and the Grand Princess ship in California. Passengers and crew on both ships were quarantined on board after previous guests, who didn’t have any symptoms while aboard each of the ships, tested positive for COVID-19 after landing ashore.

The RNA, the genetic material of the virus that causes COVID-19, “was identified on a variety of surfaces in cabins of both symptomatic and asymptomatic infected passengers up to 17 days after cabins were vacated on the Diamond Princess but before disinfection procedures had been conducted,” the researchers wrote, adding that the finding doesn’t necessarily mean the virus spread by surface.

WestEastSpace mapped out NASA locations on a map of COVID19 impacted areas of USA from www.usafacts.org as of March 23rd, 2020With the launch window for NASA’s Mars Perseverance rover opening in a little less than four months, there are nearly daily pre-launch milestones to complete the rover pre flight activities at the Kennedy Space Center in Cape Canaveral, Florida. Tight schedules on complex missions usually do not mix well. Now NASA has to contend with another challenge. COVID19.

NASA Leadership Assessing Mission Impacts of Coronavirus

The world has come to a standstill and is in the grasps of the COVID-19. The world stock markets have come crashing down 30% as supply chains and companies attempt to deal with government response and public fear. Airlines and hotels have had to contend with decreased travel and lodging requirements. Logistics is impacted as factories in various countries deal with increased difficulty and requirements to obtain goods. Factories are closed leading to shortages for truckers, material movers, cargo agents, and other occupations directly involved in moving goods. Companies shift to working remotely in an attempt to comply with government guidance in attempts to minimize the impact of the virus. One Mars mission has already been sidelined because of COVID19. NASA also needs to contend with these challenges.

Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edit their own genetic instructions not only within the nucleus of their neurons, but also within the axon — the long, slender neural projections that transmit electrical impulses to other neurons. This is the first time that edits to genetic information have been observed outside of the nucleus of an animal cell.

The study, led by Isabel C. Vallecillo-Viejo and Joshua Rosenthal at the Marine Biological Laboratory (MBL), Woods Hole, is published this week in Nucleic Acids Research.

The discovery provides another jolt to the “central dogma” of molecular biology, which states that genetic information is passed faithfully from DNA to messenger RNA to the synthesis of proteins. In 2015, Rosenthal and colleagues discovered that squid “edit” their messenger RNA instructions to an extraordinary degree — orders of magnitude more than humans do — allowing them to fine-tune the type of proteins that will be produced in the nervous system.

Doctor groups are recommending testing and isolation for people who lose their ability to smell and taste, even if they have no other symptoms.

We may have it all wrong when it comes to this accidental invasive species.

Researchers have designed a brain-computer interface to read your mind better than ever.

But don’t think this is a replacement for pumping some iron.
