  • New nasal nanodrops wipe out brain tumors in mice
    A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach the brain without invasive surgery. When paired with drugs that boost T-cell activity, the treatment eliminated tumors in mice and built long-lasting immunity. The results suggest a powerful new […]
  • Stem cell therapy helps AMD patients see again
    A first-of-its-kind trial is testing adult stem cell transplants for advanced dry macular degeneration. Early results show the treatment is safe and can significantly improve vision, even in severely affected patients. Participants gained measurable sight improvements in the treated eye. Researchers are now monitoring higher-dose groups as the therapy advances toward later trial phases.
  • Just a few cigarettes a day can damage your heart for decades
    People who smoke only a couple of cigarettes a day still face surprisingly high risks of heart problems and early death. A large review of long-term studies shows that even very light smokers can see their risk of heart failure climb sharply. While quitting leads to major health improvements, some risk remains for decades. The […]
  • Scientists reveal a hidden hormone switch for learning
    Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s activity was blocked. The findings help explain how hormonal cycles influence cognitive performance and psychiatric symptoms. This connection offers a new path for understanding brain disorders tied […]
  • New evidence shows tirzepatide and semaglutide strongly protect the heart
    A massive real-world study comparing tirzepatide and semaglutide reveals both drugs deliver strong, early cardiovascular protection—reducing heart attack, stroke, and death in adults with type 2 diabetes. While companies have claimed large differences favoring their own medications, researchers found only modest distinctions between the two blockbuster GLP-1 drugs.
  • Simple amino acid supplement greatly reduces Alzheimer’s damage
    Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque levels, reduced inflammation, and improved behavior. Its strong safety record and low cost make it a promising repurposing candidate. The findings hint at a surprisingly […]
