Over 116,000 people in the US are on organ transplant waiting lists because of a shortage in healthy donated organs. Dr. Wells and his team have been harnessing the power of stem cells to grow miniature versions of human organs in the laboratory. Today, mini organs are being used to help diagnose patients and improve care and Dr. Wells and colleagues are working to generate lab grown organs for future transplantation into patients.

FB: James Wells, LinkedIn: James Wells As a Developmental Biologist, Jim Wells has spent the past two decades trying to uncover how a single cell gives rise to tissues, organs and eventually a whole organism. With this information as a roadmap, he has pioneered approaches to generate mini organs (organoids) from stem cells in the laboratory. Dr. Wells is now part of a team that is using tissue engineering to generate bigger and more functional organs in the lab that can be used for transplantation into patients in the future. Dr. Wells is a professor of Pediatrics at the Cincinnati Children’s Hospital Medical Center. He is in the Division of Developmental Biology and where he established the human pluripotent stem cell facility. He is also the Director for Basic Research in the Division of Endocrinology and was appointed Chief Scientific Officer of the Center for Stem Cell and Organoid Medicine.

US flu season arrives early, driven by an unexpected virus
NEW YORK (AP) — The U.S. winter flu season is off to its earliest start in more than 15 years.
An early barrage of illness in the South has begun to spread more broadly, and there’s a decent chance flu season could peak much earlier than normal, health officials say.
The last flu season to rev up this early was in 2003–2004 — a bad one. Some experts think the early start may mean a lot of suffering is in store, but others say it’s too early to tell.
World must prepare for biological weapons that target ethnic groups based on genetics, says Cambridge University
Biological weapons could be built which target individuals in a specific ethnic group based on their DNA, a report by the University of Cambridge has warned.
Researchers from Cambridge’s Centre for the Study of Existential Risk (CSER) said the government was failing to prepare for ‘human-driven catastrophic risks’ that could lead to mass harm and societal collapse.
In recent years advances in science such as genetic engineering, and artificial intelligence (AI) and autonomous vehicles have opened the door to a host of new threats.

Study finds aging tends to shift gears as you turn 34, 60 and 78
The blood-borne signs of aging – and indeed, perhaps the causes of aging – make three big shifts around the ages of 34, 60 and 78, a new Stanford-led study has discovered, potentially leading to new diagnostic tests and avenues of anti-aging research.
The study measured levels of nearly 3,000 individual proteins in the plasma of small blood samples from 4,263 people aged between 18 and 95, and found that 1,379 of these proteins varied significantly with a subject’s age. Indeed, with information about levels of just 373 of these proteins, the researchers found they could predict a subject’s age “with great accuracy,” and an even smaller subset of just nine proteins could do a “passable” job.
Proteins are the body’s workhorses, carrying out instructions from all the body’s cells. Changes in their levels in our blood reflect the starting, stopping and changing of different biological processes. The researchers found that these changes were often quite sudden – levels of a protein would remain stable in the blood for years, and then rapidly plunge or leap, rather than showing a steady increase or decline.
Israeli start-up to process blood test in 10 minutes cleared by US FDA
Israeli startup Sight Diagnostics said on Wednesday the US Food and Drug Administration had cleared its device that can process results for the most commonly needed blood test in about ten minutes. The regulator’s nod means that laboratories that run relatively lesser tests on a day to day basis may also be able to conduct the complete blood count (CBC) test with just two drops of blood.
