Summary: Researchers used artificial intelligence to predict how enzymes interact with various substrates. The team developed an AI model that can accurately predict whether an enzyme can work with a particular molecule.
Their enzyme substrate prediction (ESP) model provides a valuable tool for drug research and biotechnology, with applications ranging from the creation of new drugs to the production of biofuels.
Scientists have figured out a way to retrieve tiny traces of human genetic material called environmental DNA (eDNA) from thin air.
Lifespan by simply slowing the aging of an organ, such as the intestine? CNRS researchers have discovered how to extend the life expectancy of zebrafish by reactivating a gene within intestinal cells. The results were published in the journal Nature Aging on May 4, 2023.
The intestine plays a crucial role in an anti-aging approach as well as general health. Over a century ago, Elie Metchnikov observed that aging ensued from increased inflammation of the intestine and microbial infiltration within blood circulation. The more we age, the less the digestive tract serves as a barrier, allowing the undesirable particles and bacteria that cause the more rapid aging of the organism to pass through.
In a new study, Miguel Godinho Ferreira and his team at the Institute for Research on Cancer and Aging (Ircan) in Nice (CNRS/Inserm/Université Côte d’Azur) have studied the impact on aging of telomere length in the intestinal cells of zebrafish. As with humans, these chromosome extremities shrink faster in the intestine than in other organs during the course of a life, which is why this process plays such an important role in aging.
Join us at 6:00 pm EST (11:00 pm UTC) for our Perpetual Life Hybrid Party live from our new location at 950 South Cypress Road in Pompano Beach, FL, & socialize with Immortalists from Around the World, hosted by hosted by Tonya Scholz & Rudi Hoffman.
Stay “In Zoom” for our 7:00 pm (12:00 am-midnight UTC) YouTube Streaming Service. This month, we are excited to have two speakers. First, Erik Nelson, Director of Clinical Programs at The Healthy Longevity Clinic, will present “Into the World of Longevity Medicine.”

Quantum biology explores how quantum effects influence biological processes, potentially leading to breakthroughs in medicine and biotechnology. Despite the assumption that quantum effects rapidly disappear in biological systems, research suggests these effects play a key role in physiological processes. This opens up the possibility of manipulating these processes to create non-invasive, remote-controlled therapeutic devices. However, achieving this requires a new, interdisciplinary approach to scientific research.
Imagine using your cell phone to control the activity of your own cells to treat injuries and diseases. It sounds like something from the imagination of an overly optimistic science fiction writer. But this may one day be a possibility through the emerging field of quantum biology.
Over the past few decades, scientists have made incredible progress in understanding and manipulating biological systems at increasingly small scales, from protein folding to genetic engineering. And yet, the extent to which quantum effects influence living systems remains barely understood.
A new method of controlling the shape of tiny particles about one tenth of the width of human hair could make the technology that powers our daily lives more stable and more efficient, scientists claim.
The process, which transforms the structure of microscopic semiconductor materials known as quantum dots, provides industry with opportunities to optimize optoelectronics, energy harvesting, photonics, and biomedical imaging technologies, according to the Cardiff University-led team.
Their study, published in Nano Letters, used a process called nanofaceting—the formation of small, flat surfaces on nanoparticles—to manipulate the quantum dots into a variety of shapes called nanocrystals.
For the first time, scientists have created healthy, fertile mouse pups from the DNA of two adult males — no female DNA required.
While the research is currently only a proof of concept and has yet to be peer-reviewed, the team behind the process thinks it could translate to people — meaning two men could potentially have biological children together one day.
Reproduction 2.0: For nearly all of humanity’s existence, reproduction has required sperm from one man and an egg from one woman — put the two together in a welcoming womb, and nine months later, you have a baby.
John Yang:
Artificial intelligence is finding its place in all sorts of scientific fields, and perhaps none holds more life savings promise than healthcare programs are learning to answer patient’s medical questions and diagnose illnesses. But there’s still some problems to be worked out. Earlier, I spoke with Dr. Isaac Kohane, the editor-in-chief of the New England Journal of Medicine AI, and the chair of Harvard’s Department of Biomedical Informatics. I asked him about AI’s potential in medicine.
Dr. Isaac Kohane, Editor-in-Chief, New England Journal of Medicine AI: Doctors can definitely use AI as an augmentation, so they’ll remember or be reminded of all the things that they should know about their patient, their specific patient, and all other similar patients like them.
The Mediterranean diet has become famous far beyond its namesake sea, as research increasingly supports its longstanding reputation for boosting health and longevity.
Studies have shown that people on the Mediterranean diet – which emphasizes plant-based foods and fish, and not so much red meat or dairy – tend to be healthier in multiple ways, with lower rates of heart disease, cancer, diabetes, dementia, and overall mortality.
But why? Despite strong evidence for health benefits, it remains unclear how exactly this mix of foods, at the cellular level, can lengthen lifespan.
Many of us will be familiar with feelings of sluggishness and lethargy in the afternoon, but for those with obstructive sleep apnea (OSA), the problem is more severe.
Fortunately, researchers have now identified a drug that offers a good chance of helping. And no, it doesn’t come in espresso form.
Excessive daytime sleepiness (EDS) for people who have OSA can severely affect daily life. It means having overwhelming urges to sleep at inappropriate times – while driving or eating, for example – and often struggle to complete simple tasks.
