Scientists say NAD+ could slow aging and fight Alzheimer's and Parkinson's
A global team of leading scientists is zeroing in on a tiny but powerful molecule that could reshape how we age. Known as NAD⁺, it plays a crucial role in keeping our cells energized, repairing DNA, and maintaining overall health-but its levels steadily decline over time, potentially fueling disease...
Insulin pills may soon replace daily injections
For over a century, scientists have chased the dream of insulin pills, but the digestive system kept destroying the drug before it could work-forcing millions of patients to rely on daily injections. Now, researchers at Kumamoto University have developed a clever workaround using a tiny peptide that...
Scientists discover hormone that may stop chronic back pain at its source
A new study suggests a widely used bone hormone could help relieve chronic back pain in an unexpected way. Instead of just strengthening bone, it appears to stop pain-sensing nerves from growing into damaged spinal areas. In animal models, this led to stronger spinal tissue and reduced pain sensitiv...
Women over 50 lost 35% more weight with this surprising combo
Postmenopausal women may have a powerful new edge in the battle against weight gain. A Mayo Clinic study found that those using menopausal hormone therapy while taking the obesity drug tirzepatide lost about 35% more weight than those on the drug alone. The findings hint at a surprising synergy betw...
This new tooth powder whitens teeth without damage
Researchers have developed a teeth-whitening powder that works with the vibrations of an electric toothbrush to safely remove stains. Unlike traditional whiteners, it not only brightens teeth but also repairs enamel and supports healthy oral bacteria. Lab tests showed dramatic whitening effects, whi...
Scientists discover Alzheimer's hidden "death switch" in the brain
Scientists have uncovered a hidden "death switch" in the brain that may be driving Alzheimer's disease-and even found a way to turn it off in mice. The culprit is a toxic pairing of two proteins that, when combined, triggers the destruction of brain cells and fuels memory loss. By using a new compou...
New blood test could catch pancreatic cancer before it's too late
A new blood test could change the outlook for one of the deadliest cancers-pancreatic cancer-by catching it much earlier than ever before. Researchers identified two previously unknown proteins in the blood that, when combined with existing markers, dramatically improved detection accuracy. The four...
A promising fatty liver treatment may raise cancer risk
A surprising new study reveals that blocking a supposedly protective enzyme, Caspase-2, could actually backfire-raising the risk of chronic liver damage and cancer over time. Researchers found that without this enzyme, liver cells grow abnormally large and accumulate genetic damage, leading to infla...
Scientists discover surprising brain trigger behind high blood pressure
Scientists have uncovered a surprising brain-based trigger for high blood pressure, tracing it to a small region in the brainstem that normally controls breathing. This area, which kicks in during forceful exhalations like coughing, laughing, or exercise, also appears to activate nerves that tighten...
Weight loss drug Ozempic cuts depression, anxiety, and addiction risk
GLP-1 medications like semaglutide (Ozempic) may offer unexpected mental health benefits alongside weight loss. A large study found major drops in depression, anxiety, and psychiatric-related hospital visits among users. Even substance use disorders were significantly lower during treatment. Researc...
Hidden antibiotics in river fish spark new food safety fears
Antibiotics are accumulating in a major Brazilian river, especially during the dry season when pollution becomes more concentrated. Scientists even detected a banned drug inside fish sold for food, raising concerns about human exposure. A common aquatic plant showed promise in removing these chemica...
New pill cuts "bad" cholesterol by 60% in major trial
A new pill, enlicitide, reduced LDL ("bad") cholesterol by about 60% in a large clinical trial, matching the power of injectable therapies. Because it's taken orally, it could overcome one of the biggest barriers keeping patients from using current treatments. Researchers say many people still don't...
New AI tool predicts cancer spread with surprising accuracy
Researchers have discovered that cancer spread isn't random-it follows a kind of biological "program." By studying colon tumor cells, they identified gene patterns that signal whether a cancer is likely to metastasize. Their AI model, MangroveGS, can predict this risk with about 80% accuracy and eve...
Scientists turn probiotic bacteria into tumor-hunting cancer killers
Scientists have engineered probiotic bacteria to act as tumor-seeking drug factories. In mice, these bacteria infiltrated tumors and produced a cancer-fighting drug right where it was needed. This targeted approach could make treatments more effective and reduce side effects. More research is needed...
These "forever chemicals" could be weakening kids' bones for life
"Forever chemicals" may be affecting kids in ways that last a lifetime. A new study links early PFAS exposure to lower bone density during the teen years, especially in girls. Researchers also found that when exposure happens may play a key role. Reducing exposure during childhood could help protect...
Men are losing a key chromosome with age and it may be deadly
Aging men often lose the Y chromosome in a growing number of their cells-and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer's, and shorter lifespans. Researchers suspect Y-less cells may grow faster and disrupt normal body functions. Wh...
Huge study finds no evidence cannabis helps anxiety, depression, or PTSD
The largest review of medicinal cannabis to date found it doesn't effectively treat anxiety, depression, or PTSD-despite millions using it for those reasons. Researchers warn it could even make mental health worse, raising risks like psychosis and addiction while delaying proven treatments. Some lim...
This common vaccine cuts heart risk nearly in half in new study
A shingles vaccine might double as a powerful heart protector. In people already at high risk, it cut major cardiac events by 46% and deaths by an impressive 66% within a year. Scientists think preventing shingles may also stop clot-related complications that can lead to heart attacks and strokes. T...
This virus therapy supercharges the immune system against brain cancer
Scientists have found a way to make one of the most aggressive brain tumors vulnerable to the immune system. A single injection of a modified virus can invade glioblastoma, kill cancer cells, and summon immune fighters deep into the tumor. These immune cells persist and attack, which was linked to l...
Gum disease bacterium linked to breast cancer growth and spread
A common oral bacterium tied to gum disease may help spark and fuel breast cancer, according to new research. Scientists discovered it can travel through the bloodstream to breast tissue, where it causes DNA damage and speeds tumor growth and spread. It also appears to make cancer cells more aggress...
