From One Cell review: Embryology and the future of medicine

Posted by in categories: biotech/medical, health

From marigolds to human babies, most complex organisms start as a single-celled embryo. In his new book, Ben Stanger explores what our humble origins could teach us about health and disease.

Researchers discover how stem cells choose their identity

Posted by in category: biotech/medical

AMOLF researchers discovered that stem cells first specialize into a functional cell and then move to their proper location—rather than the other way around.

Researchers at AMOLF, Amsterdam, and the Hubrecht institute, Utrecht, revealed a new model to show how specialize into functional cells. They found that their position in the organ is not as important as current models claim. Rather, stem cells choose their identity first and only then move to their appropriate position.

These discoveries were made using and the new TypeTracker technique, which can now be used to understand other organs at the cellular level and the effects of mutations and medications. The findings were published on August 18 in the journal Science Advances.

Researchers reverse hearing loss in mice

Posted by in categories: biotech/medical, genetics, neuroscience

The research, published in Proceedings of the National Academy of Sciences, used a genetic approach to fix deafness in mice with a defective Spns2 gene, restoring their hearing abilities in low and middle frequency ranges. Researchers say this proof-of-concept study suggests that hearing impairment resulting from reduced gene activity may be reversible.

Over half of adults in their 70s experience significant hearing loss. Impaired hearing is associated with an increased likelihood of experiencing depression and cognitive decline, as well as being a major predictor of dementia. While hearing aids and cochlear implants may be useful, they do not restore normal hearing function, and neither do they halt disease progression in the ear. There is a significant unmet need for medical approaches that slow down or reverse hearing loss.


New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London has successfully reversed hearing loss in mice.

How Long Should You Live? Star Trek, Dr. Emanuel, & The Ethics of Life Extension

Posted by in categories: biotech/medical, ethics, life extension

I will try to live as long as possible.


Dr. Ezekiel Emanuel plans to reject life-extending medical care at the age of 75. The reason he does this is quite similar to why the Kaelons commit ritual suicide in Star Trek: The Next Generation. Does this make sense?

Regeneron’s Antibody Gets FDA Approval for Ultra-Rare Hereditary Disease

Posted by in category: biotech/medical

The FDA on Friday approved Regeneron Pharmaceuticals’ Veopoz (pozelimab-bbfg), the first and only treatment indicated specifically for CHAPLE disease, also known as CD55-deficient protein-losing enteropathy, according to the company.

A fully human monoclonal antibody, Veopoz is approved for the treatment of adult and pediatric patients 1 year of age and older with CHAPLE, an ultra-rare hereditary disease that can cause potentially life-threatening gastrointestinal and cardiovascular symptoms.

- CHAPLE—which stands for complement hyperactivation, angiopathic thrombosis, and protein-losing enteropathy—is an inherited immune disease that causes the complement system (the part of your immune system that defends the body against injury and foreign invaders like bacteria and viruses) to become overactive.-FDA.

Consumer Health: Are you considering contact lenses?

Posted by in categories: biotech/medical, health

Contact Lens Health Week will be observed Aug. 21–25, which makes this a good time to learn more about contact lenses and whether they might be right for you.

Eyeglasses can be fun and fashionable. And they’re a safe and effective way to provide vision correction for most people. Contact lenses also can provide a safe and effective way to correct your vision, and more than 45 million people in the U.S. wear contact lenses, according to the Centers for Disease Control and Prevention.

If you’re considering switching to contact lenses, here are some things you should consider.

A 77-year-old talks to an AI-companion robot called ElliQ over a dozen times daily to combat her loneliness: ‘It really is like having somebody else in here’

Posted by in categories: biotech/medical, robotics/AI

Hundreds of elders are using an AI-powered robot to combat their loneliness — and it appears to be offering companionship to one New Yorker getting daily breast cancer treatments.

Priscilla O’Kesson, a 77-year-old, told Spectrum News she has been using ElliQ, an AI-powered robot made by Israeli startup Intuition Robotics, to keep her company at her home in a town in Greene County called Catskill.

The AI-robot, designed to help older adults age on their own, uses voice commands and on-screen instructions to talk to and interact with users in real-time. ElliQ can conduct daily check-ins, act as a personal trainer, play games to stimulate the brain, and track their wellness goals, according to the robotics company.

One Gene Can Have a Major Impact on Strep Infection Severity

Posted by in categories: biotech/medical, genetics

Group A streptococci are one of the most common pathogens that humans are exposed to, and they can cause infections with a wide range of severities, from mild rashes and sore throats to flesh-eating and systemic infections that can be fatal. The number of these infections is also on the rise, although the reasons are unclear. Now researchers have learned more about why these pathogens can be mild in some people, and hit others hard. The findings have been reported in Nature Communications.

Scientists suspected that some interaction between a person’s genetics and the bacterial pathogen could be leading to such varied outcomes, said study co-author Fredric Carlsson, a researcher at Lund University.

Postdoctoral Fellow in Microbial Genomics, Bacterial Pathogenesis and Antimicrobial Resistance Unit

Posted by in categories: biotech/medical, computing, health

The National Institute of Allergy and Infectious Diseases (NIAID), one of the largest institutes in the National Institutes of Health (NIH), part of the Department of Health and Human Services (HHS), conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases. The Bacterial Pathogenesis and Antimicrobial Resistance Unit (chief John Dekker) in the Laboratory of Clinical Immunology and Microbiology in the Division of Intramural Research (DIR) within NIAID seeks candidates for a postdoctoral fellowship position in microbial genomics.

This position will offer a unique opportunity to work at the intersection of pathogen genomics, systems biology, and clinical infectious diseases. The lab uses a variety of genomics, transcriptomics, metabolomics, imaging, and molecular approaches to study bacterial pathogens and antimicrobial resistance, with a focus on intra-host evolution in the context of infection. Access to state-of-the-art short-and long-read sequencing, metabolomics, optical, and computational resources is available. See more information about the Bacterial Pathogenesis and Antimicrobial Resistance Unit under chief John P. Dekker and an example of their recent work.
