That’s good funding.
Berlin, Gerrmany — Michael Greve, founder of the Forever Healthy Foundation and owner of Kizoo Technology Ventures, announced today that he will make available an additional €300 million to be invested in rejuvenation biotech.
The funds, to be deployed via Kizoo, will be used to create and support more startups in the rejuvenation space. They will also allow Kizoo to maintain a strong commitment to its key startups during follow-up rounds and to advance the therapies from clinical development to public availability.
With this €300 million commitment, Michael Greve and Kizoo double down on their mission to accelerate the advent of rejuvenation biotechnology by doing lighthouse investments in entirely new, repair-based approaches that treat the root causes of aging and thus overcome age-related diseases. Through the creation of successful companies, they seek to inspire scientists, investors, and the general public by demonstrating that human rejuvenation is not science fiction anymore and that the resulting therapies are affordable and uncomplicated.
The human cells grew inside all 132 of the embryos after just 24 hours. After ten days, 103 chimeric embryos remained. By day 19, however, only three chimeras were left alive – and they were then terminated.
“This knowledge will allow us to go back now and try to re-engineer these pathways that are successful for allowing appropriate development of human cells in these other animals,” Juan Carlos Izpisua Belmonte, genetics professor at the Salk Institute for Biological Sciences in La Jolla, California and co-author of the study, told NPR.
“We are very, very excited,” he added.
As India struggles to curb the spread of COVID-19 and step up vaccinations, experts have warned the country to prepare for future waves of the pandemic. It’s hoped that US support for a vaccine waiver will see results.
Many people with diabetes endure multiple, painful finger pricks each day to measure their blood glucose. Now, researchers reporting in ACS Sensors have developed a device that can measure glucose in sweat with the touch of a fingertip, and then a personalized algorithm provides an accurate estimate of blood glucose levels.
According to the American Diabetes Association, more than 34 million children and adults in the U.S. have diabetes. Although self-monitoring of blood glucose is a critical part of diabetes management, the pain and inconvenience caused by finger-stick blood sampling can keep people from testing as often as they should.
The researchers made a touch-based sweat glucose sensor with a polyvinyl alcohol hydrogel on top of an electrochemical sensor, which was screen-printed onto a flexible plastic strip. When a volunteer placed their fingertip on the sensor surface for 1 minute, the hydrogel absorbed tiny amounts of sweat. Inside the sensor, glucose in the sweat underwent an enzymatic reaction that resulted in a small electrical current that was detected by a hand-held device.
Needless to say, DNA is the “instructions” via which our genes are transferred between us and our offspring. And RNA is in charge of regulating the production of proteins in a body, and its so-called “instructions” that it gives are for cellular structure.
To be clear: RNA and DNA serve different functions, and, as the Centers for Disease Control and Prevention (CDC) explains, mRNA vaccines don’t affect or even interact with our DNA at all.
In this week’s Pandemic Problems column, a reader asks how to explain mRNA vaccines to a worried family member.
CHOP team treated patient with the condition, known as PU.MA, thanks to a bone marrow donation from the patient’s older brother.
When Luke Terrio was about seven months old, his mother began to realize something was off. He had constant ear infections, developed red spots on his face, and was tired all the time. His development stagnated, and the antibiotics given to treat his frequent infections stopped working. His primary care doctor at Children’s Hospital of Philadelphia (CHOP) ordered a series of blood tests and quickly realized something was wrong: Luke had no antibodies.
At first, the CHOP specialists treating Luke thought he might have X-linked agammaglobulinemia (XLA), a rare immunodeficiency syndrome seen in children. However, as the CHOP research team continued investigating Luke’s case, they realized Luke’s condition was unlike any disease described before.
What Are ‘COVID Nails’—And Are They a Sign You’ve Had the Virus? Here’s What Doctors Say.
Tim Spector, a British epidemiologist and principal investigator of the Zoe COVID Symptom Study app, recently tweeted about the phenomenon and included a photo of COVID nails, writing, “Do your nails look odd? COVID nails are increasingly being recognized as the nails recover after infection and the growth recovers leaving a clear line. Can occur without skin rashes and appears harmless.”
Some people in the comments said they’ve definitely experienced this after having the coronavirus. “I noticed this and also hair loss 3 months after covid,” one wrote. “These were my post Covid nails! This was approx 2 months after the infection,” another said.
Plenty of others had questions in the comments section about COVID nails, what they look like, and if they’re something to worry about. Here’s what you need to know about COVID nails.
Mastering meat production in this way will lead to advances in medical science and treatment.
“Cultured meat also ultimately offers the opportunity to create meat products that are more well-defined, tunable, and potentially healthier than meat products today, which are constrained by the biological limitations of the domestic animals from which they are derived.”
Owing to advances in industrial-scale cell culture process, the production of cultured meat has been largely standardized. Typically stem cells are first seeded into extracellular matrix scaffolds usually made of edible biomaterials like collagen and chitin. To support cellular metabolic activities, culture media containing nutrients like glucose and sera are next added to the bioreactor where continual mechanical motion facilitates good diffusion of nutrients and oxygen into and removal of metabolic waste products from the cells. After about 2–8 weeks, the cells grow into tissue layers and can be harvested and packaged.
Several key challenges remain in producing cultured meat including access to (proprietary) cell lines, high raw material cost, animal-source nutrients, and limited manufacturing scale. Despite this, immense progress has been made over the last decade. Here, we discuss the challenges and solutions to deliver cultured meat from a lab bench to a dining table.
