A team of scientists successfully achieved 53% reverse aging in old rats with blood plasma from young rats, in an astounding leap forward for the erstwhile-controversial aging field of study.

Claims carried in numerous media outlets last month suggested the 36-year-old had died after botched heart surgery, or was alternatively in a vegetative state.
Speculation was fuelled after he missed the birth anniversary celebrations of state founder Kim Il-sung, his grandfather, on April 15.
In a study published today (May 13, 2020) in the New England Journal of Medicine, scientists in the U.S. and Japan report that in the laboratory, cats can readily become infected with SARS-CoV-2, the virus that causes COVID-19, and may be able to pass the virus to other cats.
Professor of Pathobiological Sciences at the University of Wisconsin School of Veterinary Medicine Yoshihiro Kawaoka led the study, in which researchers administered to three cats SARS-CoV-2 isolated from a human patient. The following day, the researchers swabbed the nasal passages of the cats and were able to detect the virus in two of the animals. Within three days, they detected the virus in all of the cats.
The day after the researchers administered virus to the first three cats, they placed another cat in each of their cages. Researchers did not administer SARS-CoV-2 virus to these cats.
Doctors regularly warn their patients that having high levels of triglycerides, a major dietary fat, can increase the risk of heart disease, diabetes, obesity and fatty liver disease. There is considerable interest in finding novel ways to effectively regulate triglycerides in the blood to help manage these potentially life-threatening common conditions.
Now, researchers at Baylor College of Medicine, Princeton University and Texas A&M University are closer to achieving this goal after discovering the 3D structure and mode of action of diacylglycerol O-acyltransferase-1 (DGAT1), the enzyme that synthesizes triglycerides and also is required for human dietary fat absorption and storage. DGAT1 is a known target to treat obesity and other metabolic diseases, so having a detailed understanding of what DGAT1 looks like and how it works opens opportunities for designing novel strategies for managing these conditions. The findings are published in the journal Nature.
“DGAT1 is a particularly interesting enzyme because it synthesizes triglycerides, which are the main component of hard fat, the type of fat usually found in the belly or midsection in our body. Triglycerides also are part of the particles that transport cholesterol—high-density lipoproteins (HDL, or ‘good cholesterol’), and low-density and very-low-density lipoproteins (LDL and VLDL, or ‘bad cholesterols’),” said co-corresponding author Dr. Ming Zhou, Ruth McLean Bowman Bowers Professor in Biochemistry in the Department of Biochemistry and Molecular Biology at Baylor. “Learning to regulate this enzyme can help regulate fat synthesis and potentially manage related conditions.”
The 42-year-old virologist and epidemiologist, who has responded to multiple outbreaks around the world, got sick about three days after a flight to his home in New Orleans.
“I had a mask on, I had gloves on, I did my normal wipes routine … but obviously, you can still get it through your eyes,” Fair said on the “TODAY” show from his hospital bed. “And of course I wasn’t wearing goggles on the flight.”
“That’s one of the three known routes of getting this infection that we just don’t pay a lot of attention to; we tend to pay attention to the nose and mouth because that is the most common route,” he said. “But you know, droplets landing on your eyes are just as infectious.”
This could essentially in the wrong hands be very bad but in the positive ways it could cure anything.
Right now the world is at war. But this is no ordinary war. It’s a fight with an organism so small we can only detect it through use of a microscope — and if we don’t stop it, it could kill millions of us in the next several decades. No, I’m not talking about COVID-19, though that organism is the one on everyone’s mind right now. I’m talking about antibiotic-resistant bacteria.
You see, more than 700,000 people died globally from bacterial infections last year — 35,000 of them in the U.S. If we do nothing, that number could grow to 10 million annually by 2050, according to a United Nations report.

A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.
MicroRNAs play a big role in our body in controlling gene expression, and also are a front line when viruses invade, latching onto and cutting the RNA, the genetic material of the virus, says Dr. Sadanand Fulzele, aging researcher in the Department of Medicine and Center for Healthy Aging at the Medical College of Georgia at Augusta University.
But with age and some chronic medical conditions, the attacking microRNA numbers dwindle, reducing our ability to respond to viruses, says Dr. Carlos M. Isales, co-director of the MCG Center for Healthy Aging and chief of the MCG Division of Endocrinology, Diabetes and Metabolism.

Detailed analysis from the epicentre of the Italian COVID-19 outbreak describes increase in cases of rare Kawasaki-like disease in young children, adding to reports of similar cases from New York, USA and South East England, UK. Syndrome is rare and experts stress that children remain minimally affected by SARS-CoV-2 infection overall.
Doctors in the Bergamo province of Italy have described a series of ten cases of young children with symptoms similar to a rare inflammatory disease called Kawasaki Disease appearing since the COVID-19 pandemic arose in the Lombardy region of Northern Italy, in a report published today in The Lancet.
Only 19 children had been diagnosed with the condition in that area in the five years up to the middle of February 2020, but there were 10 cases between 18 February and 20 April 2020. The latest reports could represent a 30-fold increase in the number of cases, although researchers caution that it is difficult to draw firm conclusions with such small numbers.
