Josh Mitteldorf on programmed aging

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

Irina Conboy, Michael Conboy and Josh Mitteldorf discuss one of the central questions in aging research: is aging an active process of the body or is aging a passive process of damage accumulation? See the whole debate on our YouTube Channel: @HealesMovies Josh Mitteldorf, PhD, runs the blog “Aging Matters” ( and is a consultant in mathematical modeling and creative data analysis. His research areas include evolutionary ecology, biology of aging, and the epidemiology of COVID-19. On the field of aging research, he has published two books,” Cracking The Aging Code”, co-written with Dorion Sagan (…atfound-20 and “Aging is a Group-Selected Adaptation” ( Heales website (Healthy Life Extension Society): Subscribe to our newsletter: Contact e-mail: [email protected] #science #aging #rejuvenation #biology #health #longevity #antiaging #debate #stemcells #programmedaging #entropy #cancer #conboy #conboys #mitteldorf Music: Closer To Your Dream by Keys of Moon | (CC BY 4.0)

Health Risks of Concurrent Cannabis and Nicotine Use During Pregnancy

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

“There is still a great deal of stigma around the use of substances during pregnancy,” said Dr. Jamie Lo, M.D., M.C.R. “Our hope is that this research supports more open and productive conversations that ultimately result in a healthier pregnancy.”

It has long been known that smoking during pregnancy can result in bad health for newborns, but what are the consequences of smoking both nicotine and cannabis during pregnancy? This is what a recent study published in JAMA hopes to address as a team of researchers investigated the potential health risks for newborns when pregnant mothers smoke both nicotine and cannabis during pregnancy. This study holds the potential to help researchers, medical practitioners, and the public better understand the health risks of cannabis as its recreational use continues to become legalized across the United States.

“With the growing legalization of cannabis around the country, there is often a perception that cannabis is safe in pregnancy,” said Dr. Jamie Lo, M.D., M.C.R., who is an associate professor of obstetrics and gynecology at the Oregon Health & Science University School of Medicine and a co-author on the study. “Because we know that many people who use cannabis often use tobacco or nicotine products, we wanted to better understand the potential health implications on both the pregnant individual and the infant.

CRISPR Enzyme Found in Metagenomic Study Is Tiny, Yet Active and Precise

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

The results of a metagenomic study from the University of Trento suggest that the CRISPR toolbox will need to make room for another CRISPR enzyme. The disruption should be minimal because the newly identified enzyme is unusually compact. It consists of just over 1,000 amino acids. And yet it is also strongly active and highly precise. The hope is that it can be packaged with guide RNA within the tight quarters afforded by adeno-associated virus (AAV) vectors, and thereby expand the use of in vivo gene editing in therapeutic applications.

The study was led by Anna Cereseto, PhD, and Nicola Segata, PhD, of the department of cellular, computational, and integrative biology. Cereseto leads a laboratory that develops advanced genome editing technologies and their application in the medical sector. Segata is the head of a laboratory of metagenomics, where he studies the variety and characteristics of the human microbiome and its role in health. Their collaboration has led to the identification, in a bacterium of the intestine, of new CRISPR-Cas9 molecules that could have a clinical potential to treat genetic diseases.

Detailed findings from the study recently appeared in Nature Communications, in an article titled, “CoCas9 is a compact nuclease from the human microbiome for efficient and precise genome editing.”

Blautia Bacteria’s Crucial Role as a Gut Barrier Shield is Revealed

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

Western diets that are high in sugars, fats, and processed foods have been linked to a wide variety of health ailments. Now, researchers have determined that Western diets can also disrupt the crucial barrier in the gastrointestinal tract known as the gut mucosa. This disruption can raise an individual’s risk of inflammation and infectious disease. Scientists have also identified a gut microbe called Blautia that has an important role in shielding the gut mucosa. The findings have been reported in Nature Communications.

“Our results contribute to an increased understanding of how the intestinal bacteria and the mucus layer work together, which may eventually lead to new treatment strategies for diseases linked to the Western diet such as the inflammatory bowel disease ulcerative colitis,” said first study author Sandra Holmberg, a graduate student at Umeå University.

When Antibiotics Fail: MIT Scientists Use AI To Target “Sleeper” Bacteria

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

Most antibiotics target metabolically active bacteria, but with artificial intelligence, researchers can efficiently screen compounds that are lethal to dormant microbes.

Since the 1970s, modern antibiotic discovery has been experiencing a lull. Now the World Health Organization has declared the antimicrobial resistance crisis as one of the top 10 global public health threats.

When an infection is treated repeatedly, clinicians run the risk of bacteria becoming resistant to the antibiotics. But why would an infection return after proper antibiotic treatment? One well-documented possibility is that the bacteria are becoming metabolically inert, escaping detection of traditional antibiotics that only respond to metabolic activity. When the danger has passed, the bacteria return to life and the infection reappears.

Temporal dynamics of the multi-omic response to endurance exercise training

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

A study in Nature identifies molecular responses to endurance exercise training in rats, including sex-specific responses. The findings may offer new insights into the impact of exercise on health and disease. Read the paper:

Temporal multi-omic analysis of tissues from rats undergoing up to eight weeks of endurance exercise training reveals widespread shared, tissue-specific and sex-specific changes, including immune, metabolic, stress response and mitochondrial pathways.
