Scientists think they’ve cracked the mystery of human right-handedness
A new study suggests humans became overwhelmingly right-handed because of two major evolutionary shifts: walking on two legs and developing much larger brains. Researchers found that as human ancestors evolved, their right-hand preference steadily intensified — transforming a mild tendency into one of humanity’s most distinctive traits.

Scientists uncover surprising health benefits of watermelon
Studies suggest watermelon could be a hidden powerhouse for better health. Researchers found that people who eat watermelon tend to have higher-quality diets packed with more vitamins, fiber, and antioxidants — while consuming less added sugar and saturated fat. Another study showed watermelon juice may help protect blood vessel function and support heart health.
Scientists reveal how seven days of fasting transforms the human body
Scientists have discovered that the human body undergoes a dramatic internal transformation during extended fasting, with major changes appearing only after about three days without food. In a seven-day water-only fasting study, researchers tracked thousands of proteins in the blood and found widespread shifts affecting organs throughout the body — including the brain. While the body quickly switches from burning glucose to fat, the most intriguing biological changes linked to potential health benefits didn’t emerge until later in the fast.
Scientists reverse Alzheimer’s in mice with breakthrough nanotechnology
A new nanotechnology treatment reversed Alzheimer’s symptoms in mice by restoring the brain’s natural cleanup system. The specially engineered nanoparticles helped clear toxic amyloid proteins from the brain and repair the blood-brain barrier, which normally protects and regulates the brain’s environment. In one striking experiment, elderly mice treated with the therapy later behaved like healthy younger mice.
Microglial senescence and epigenetic reprogramming in alzheimer's disease: An immunometabolic perspective
Microglial senescence has emerged as a potentially important aging-related mechanism in Alzheimer's disease (AD), shaped in part by epigenetic reprogramming and closely coupled to immunometabolic dysfunction. While microglia initially mount adaptive responses to amyloid-beta (Aβ), tau, and tissue stress, persistent exposure to chronic neurodegenerative cues may drive subsets of microglia toward senescence-like states characterized by altered chromatin regulation, transcriptional remodeling,...
