Even mild concussion can cause long-lasting effects to the brain, according to researchers at the University of Cambridge. Using data from a Europe-wide study, the team has shown that for almost a half of all people who receive a knock to the head, there are changes in how regions of the brain commu
During learning, the brain requires an exceptional amount of glucose to be imported into specific neural circuits, where it is used to form new memory-related proteins. Adler et al. discover that microglia, the resident immune cells of the brain, are critical for this process via a mechanism called microglial-metabolic coupling.
A teary eye, a furrowed eyebrow, creases at the edge of the eye tell us what a person is feeling without them having to express it with words. New data indicate that eyes might be the window to the soul, but with curtains blocking half of their view, because the eyes alone do not contain enough information for our brain to derive emotions solely from them.
Researchers from the College of Wooster, USA, wanted to understand how much we actually rely on the eyes versus the whole face to recognize emotions. After examining participants’ brain activity using EEG (electroencephalography) as they viewed photographs of people displaying different emotions, they discovered that people can recognize emotions both more quickly and more accurately when they can see the entire face rather than just the eyes.
Blurring details in the eyes had little impact on people’s ability to recognize facial expressions as long as the rest of the face remained visible. When details in the eyes are reduced, the ability to read emotions takes a hit if the rest of the face is concealed, suggesting that the brain uses other features to fill in the gaps when information from the eyes is missing.
An international collaboration of genetic researchers has identified more than 90 genetic regions associated with the risk of Alzheimer’s disease and related dementias. The large-scale meta-analysis reveals new biological insights into the disease, highlighting the important roles of immune processes, beta-amyloid and tau biology, and lipid metabolism.
Alzheimer’s disease is the most common cause of dementia worldwide, and its development is influenced by a complex interplay of genetic and environmental factors. Understanding the genetic architecture of the disease is essential for improving diagnosis, risk prediction, and the development of targeted therapies.
In this study, researchers combined genome-wide association data from nearly a million individuals of European ancestry, including over 128,000 Alzheimer’s disease cases and nearly 850,000 controls.
A new statistical framework developed by researchers at the Johns Hopkins Bloomberg School of Public Health, Johns Hopkins University School of Medicine, and Kaiser Permanente Northern California offers improved understanding of how genetics and environment contribute to autism risk.
Large-scale genetic studies have led to the development of genetic risk scores that estimate a person’s predisposition to diseases and health conditions based on their DNA profiles. The new framework allows researchers and clinicians to analyze these scores using family data and characterize the risk of conditions such as autism and other developmental conditions in children based on their own DNA, parental factors, and environmental influences such as maternal diet and lifestyle.
For their study published in Nature Genetics, the researchers analyzed more than 18,000 case-parent trios —autistic children and their parents—across diverse ancestral populations in the Simons Foundation Powering Autism Research for Knowledge consortium and the Genes and Environment Autism Research Study.
Spinal cord injuries can have devastating consequences for those affected. Nerve cells in the spinal cord rarely regenerate naturally, while scarring often prevents the regrowth of nerve fibers. Modern therapies attempt to influence implanted stem cells using electrical stimulation to promote the growth of new nerve cells. This approach has several drawbacks: it requires implanted electrodes, and the transplanted cells do not always survive or integrate properly into the existing tissue.
Researchers in Zurich are pursuing a new approach, which they have published in the journal Nature Materials. This involves combining therapeutic stem cells with magnetoelectric nanoparticles in such a way that the cells can be guided magnetically to the precise site of an injury and stimulate the stem cells to accelerate repair.
To achieve this, the researchers created a biohybrid microrobot, which combines living neural progenitor cells (NPCs) with a technical component in the form of specially engineered nanoparticles.
Every year, more than 2 million people in the United States are diagnosed with treatment-resistant depression.
Desperate for solutions, some brave patients are now volunteering to undergo surgery to place experimental ‘pacemakers’ into their brains.
These implanted electrodes are part of a treatment known as deep brain stimulation, which is currently used to address some cases of Parkinson’s disease and epilepsy.
In this groundbreaking conversation, Professor of Genetics and longevity scientist, Dr. David Sinclair, A.O., Ph.D., joins Sarah Grynberg to unpack the future of human aging, the science of longevity, and how we live today impacts how we age tomorrow.
From reversing blindness in mice to exploring treatments that could one day delay menopause and extend healthy human life, this episode will completely change the way you think about your body, your health, and your future.
But beyond the science, this is also a deeply human conversation about purpose, suffering, love, family, and what it truly means to live a great life.
In this episode, you will learn:
Why aging may actually be reversible.
The daily habits accelerating aging in your body right now.
How stress, loneliness, and cortisol could impact longevity.
The real science behind supplements like NMN, resveratrol, and NAD boosters.
Why exercise, sleep, and relationships matter more than you think.
What Dr. Sinclair believes is coming in the next 10 years of medicine.
How scientists are working to reverse female infertility and delay menopause.
The surprising reason your “biological age” may be younger or older than your real age.
Why suffering through disease and decline should not be considered “normal aging”
The philosophy and mindset Dr. Sinclair lives by every day.

I had Tom Benson, CEO of Mitrix on to discuss mitochondrial transplantation. We covered what mitochondria are, the discovery that your body is constantly delivering fresh mitochondria through your bloodstream (people didn’t know that mitochondria were transferred outside the cell until recently!), why we age, what kills mitochondria (stress, smoking, radiation, chemotherapy and certain antibiotics like fluoroquinolones, psych meds), why COVID destroys mitochondria and what that means for long COVID, the Alzheimer’s and Parkinson’s brain tissue regeneration research their company has already done in mice, what mitochondrial transplantation actually is and how it has already been used in pediatric heart surgery, what a bioreactor growing mitochondria for personal use might look like, and more.
