Scientists reveal what seven days of fasting does to the human body
Scientists found that prolonged fasting triggers major changes throughout the body, but many of the most interesting effects only appeared after about three days without food. The results suggest...
View ArticleCancer stem cells have an “energy addiction” scientists may be able to exploit
High-risk MDS stem cells appear to have an unexpected “energy addiction,” relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively...
View ArticleEven one strength training session a week could make a difference
Strength training may be one of the most powerful tools for staying independent as you age. Age related muscle loss, known as sarcopenia, can make everyday tasks harder while increasing the risk of...
View ArticleThis diet may slow brain aging by 2.5 years
People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss over time, with the strongest differences equivalent to about 2.5 years of delayed brain aging....
View ArticleAlzheimer’s risk gene APOE4 may have a reversible weakness
The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in...
View ArticleThis common mistake can add nearly 7 points to your blood pressure reading
A common mistake during blood pressure checks could make readings appear substantially higher than they really are. Johns Hopkins researchers found that leaving the arm unsupported can raise systolic...
View ArticleForget LASIK: Safer, cheaper vision correction without lasers or incisions
Scientists are developing a possible alternative to LASIK that reshapes the cornea without cutting it or using a laser. The technique uses a small electric potential and a specially shaped platinum...
View ArticleHidden stem cells may be fueling spinal stenosis
Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and may...
View ArticleResetting the body clock could help the brain recover after stroke
Strengthening the body’s natural daily rhythms helped mice recover after stroke by improving the brain’s waste-clearing system and reducing lingering inflammation. The approach worked even when...
View ArticleCRISPR could help doctors attack blood cancer without destroying healthy cells
Researchers used CRISPR to remove CD33 from donor stem cells, potentially giving doctors a way to attack aggressive blood cancers without destroying the healthy cells patients need after a transplant....
View ArticleRare pregnancy infections may triple the risk of autism
A major Swedish study of 3.7 million people has found that rare TORCH infections passed from a pregnant woman to the fetus are linked to much higher risks of autism and intellectual disability later in...
View ArticleThis emerging treatment could help people avoid knee replacement surgery
A minimally invasive procedure called genicular artery embolization could offer a new middle ground between conservative treatments and knee replacement for osteoarthritis. By blocking tiny blood...
View ArticleStem cells reverse stroke damage and restore movement in mice
Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the...
View ArticleScientists create a needle-thin brain implant that can do three jobs at once
A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give scientists...
View ArticleChronic stress may be quietly reshaping your heart
Chronic inflammation tied to stress, lifestyle, mental health, and socioeconomic conditions may silently change the heart for years before any symptoms appear. People with the highest inflammation...
View ArticleStanford scientists discover the human brain may actually be two separate organs
Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery also...
View ArticleScientists discover cells that cheat death and rebuild damaged tissue
Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant to...
View ArticleTextbooks may have misdrawn this basic brain structure for 100 years
Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures...
View ArticleUltra-processed foods linked to hidden muscle fat that may threaten your knees
Eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles, according to MRI scans of 615 adults at risk for knee osteoarthritis. Surprisingly, the association remained...
View ArticleScientists find a hidden retinal defense against vision loss
A naturally occurring molecule called erucamide may help the retina fight back against diseases that cause progressive vision loss. Restoring the molecule activated protective immune responses that...
