Researchers tracked changes in a critical brain receptor that helps neurons communicate and found that ketamine reshapes its activity in specific brain regions tied to mood and reward. These shifts strongly matched improvements in patients’ symptoms. The findings could help scientists develop better ways to predict who will benefit from ketamine therapy. Sun, 08 Mar 2026 19:40:58 EDT https://www.sciencedaily.com/releases/2026/03/260307213234.htm https://www.sciencedaily.com/releases/2026/03/260303050626.htm When a bone break is too severe to heal on its own, surgeons often rely on grafts or rigid metal implants — but both come with serious drawbacks. Now, researchers at ETH Zurich have created a jelly-like hydrogel that mimics the body’s natural healing process, offering a potentially game-changing alternative. Made of 97% water, this soft material can be laser-printed into intricate bone-like structures at record-breaking speeds, down to details thinner than a human hair. Tue, 03 Mar 2026 12:31:18 EST https://www.sciencedaily.com/releases/2026/03/260303050626.htm https://www.sciencedaily.com/releases/2026/03/260302030648.htm Researchers are developing a two-part therapy for type 1 diabetes: lab-made insulin-producing cells paired with custom-engineered immune cells that protect them. The goal is to stop the immune system from destroying transplanted cells — without using immunosuppressive drugs. Backed by $1 million in funding, the team hopes to create a ready-to-use treatment that could work even for people who have had diabetes for years. The approach could transform how the disease is treated. Mon, 02 Mar 2026 11:49:16 EST https://www.sciencedaily.com/releases/2026/03/260302030648.htm https://www.sciencedaily.com/releases/2026/03/260302030640.htm A tiny wireless implant is giving new hope to people blinded by advanced age-related macular degeneration. In a major international clinical trial, more than 80% of participants regained meaningful central vision, with many able to read letters and even words again after years of decline. The device replaces damaged light-sensing cells in the retina with a 2×2 mm implant that converts light into electrical signals, restoring communication between the eye and the brain.

New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, diabetes, and obesity. By 2050, nearly 60% of women in the U.S. could have high blood pressure, and close to one in three women ages 22 to 44 may already be living with some form of heart disease. Fri, 27 Feb 2026 06:18:18 EST https://www.sciencedaily.com/releases/2026/02/260227061818.htm https://www.sciencedaily.com/releases/2026/02/260224023159.htm Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one day help spot risk earlier—by looking at the brain’s vascular health, not just its plaques. Tue, 24 Feb 2026 10:21:58 EST https://www.sciencedaily.com/releases/2026/02/260224023159.htm https://www.sciencedaily.com/releases/2026/02/260224015537.htm A sweeping nationwide study has found that U.S. counties located closer to operating nuclear power plants have higher cancer death rates than those farther away. Researchers analyzed data from every nuclear facility and all U.S. counties between 2000 and 2018, adjusting for income, education, smoking, obesity, environmental conditions, and access to health care. Even after accounting for those factors, cancer mortality was higher in communities nearer to nuclear plants, particularly among older adults. Tue, 24 Feb 2026 02:26:50 EST https://www.sciencedaily.com/releases/2026/02/260224015537.htm https://www.sciencedaily.com/releases/2026/02/260216044003.htm Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage. Mon, 16 Feb 2026 07:41:25 EST https://www.sciencedaily.com/releases/2026/02/260216044003.htm https://www.sciencedaily.com/releases/2026/02/260216044002.htm A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, CRISPR, and quantum dots to generate a clear signal from just a few molecules. In lung cancer tests, it worked even in real patient serum samples. Researchers hope it could eventually power portable blood tests for cancer and other diseases.

Researchers found that oil-based ointments can be absorbed into the implant’s material, causing it to swell and sometimes break. Patient cases showed damage only when the implant directly contacted the ointment, a result confirmed in lab experiments. The findings raise concerns about standard post-surgery eye care. Fri, 16 Jan 2026 09:24:51 EST https://www.sciencedaily.com/releases/2026/01/260116085136.htm https://www.sciencedaily.com/releases/2026/01/260112001001.htm Most U.S. adults have risk factors tied to a little-known condition called CKM syndrome, which connects heart disease, kidney problems, diabetes, and obesity into one powerful health threat. When these issues overlap, the danger rises far more than when they occur alone. Despite low awareness, people are eager to learn how CKM is diagnosed and treated. Experts say understanding how these systems work together could prevent serious, life-threatening events. Mon, 12 Jan 2026 00:10:01 EST https://www.sciencedaily.com/releases/2026/01/260112001001.htm https://www.sciencedaily.com/releases/2026/01/260108231348.htm Scientists at USC are launching a new trial to test a tiny stem cell implant that could restore vision in people with advanced dry macular degeneration.

Researchers studying donated human hearts found that diabetes disrupts how heart cells produce energy, weakens the muscle’s structure, and triggers a buildup of stiff, fibrous tissue that makes it harder for the heart to pump. These changes are especially severe in people with ischemic heart disease, the most common cause of heart failure. Sun, 04 Jan 2026 00:34:03 EST https://www.sciencedaily.com/releases/2026/01/260103155034.htm https://www.sciencedaily.com/releases/2025/12/251228020016.htm Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal Alzheimer’s earlier than other commonly used brain markers. This could help physicians detect the disease earlier, before irreversible damage sets in. Sat, 03 Jan 2026 00:45:11 EST https://www.sciencedaily.com/releases/2025/12/251228020016.htm https://www.sciencedaily.com/releases/2025/12/251227082716.htm Stanford scientists have uncovered how mRNA COVID-19 vaccines can very rarely trigger heart inflammation in young men — and how that risk might be reduced. They found that the vaccines can spark a two-step immune reaction that floods the body with inflammatory signals, drawing aggressive immune cells into the heart and causing temporary injury. Sat, 27 Dec 2025 10:52:27 EST https://www.sciencedaily.com/releases/2025/12/251227082716.htm https://www.sciencedaily.com/releases/2025/12/251210092019.htm Obesity accelerates the rise of Alzheimer’s-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration and amyloid buildup. Surprisingly, blood tests detected these changes earlier than PET scans. The results point to obesity as a major, modifiable contributor to Alzheimer’s progression. Wed, 10 Dec 2025 12:23:51 EST https://www.sciencedaily.com/releases/2025/12/251210092019.htm https://www.sciencedaily.com/releases/2025/12/251209234139.htm BISC is an ultra-thin neural implant that creates a high-bandwidth wireless link between the brain and computers. Its tiny single-chip design packs tens of thousands of electrodes and supports advanced AI models for decoding movement, perception, and intent.

New research shows that being shown an X-ray can increase anxiety, make people fear exercise, and lead them to believe surgery is the only option, even when less invasive treatments could help. By focusing on clinical diagnosis instead, patients may avoid unnecessary scans, reduce health costs, and make better choices about their care.

These tiny but brilliant objects, discovered by the James Webb Space Telescope, appear far too compact and bright to fit existing models of galaxy and black hole formation. A new study suggests they may have formed within rare dark matter halos that spin unusually slowly, creating conditions that squeeze matter into incredibly dense structures. If true, these galaxies could provide vital clues about how the first black holes and galaxies came into being.

Using gold nanoparticles to spot microscopic disease markers, the device delivers results in just 15 minutes—outperforming traditional lab tests in sensitivity, speed, and affordability. Portable and costing only $2 per test, it could be deployed from remote clinics to urban hospitals, offering a lifeline for early detection and outbreak control worldwide.

The process, known as pronuclear transfer, was designed to prevent the inheritance of devastating mitochondrial diseases passed down through the mother’s DNA. The early results are highly promising: all the babies are developing normally, and the disease-causing mutations are undetectable or present at levels too low to cause harm. For families once haunted by genetic risk, this science offers more than treatment—it offers transformation.

CVI affects the ability of veins especially in the legs to return blood to the heart, often leading to swelling, pain, skin changes, and ulcers. The American Heart Association warns that CVI isn t just a cosmetic issue; it's strongly linked to cardiovascular disease and increased mortality, even when other risk factors are accounted for. Seniors, smokers, those with sedentary lifestyles, and people with obesity are particularly at risk.

A new study using advanced MRI scans found that people exposed to more air pollution showed early signs of scarring in their heart muscle, which can lead to heart failure over time. This damage showed up in both healthy individuals and people with heart conditions, and was especially noticeable in women, smokers, and those with high blood pressure.
