Scientists discover the brain has a fast lane and slow lane for clearing waste

AI has helped scientists measure the brain’s hidden cleaning system, revealing that fluid moves rapidly around its outer spaces but about 50 times more slowly through deep tissue. The discovery could eventually help researchers detect circulation problems linked to Alzheimer’s, aging, and concussions.

Dogs may hold surprising clues to human longevity

Dogs and humans may have more in common when it comes to aging than scientists realized. Researchers with the Dog Aging Project found that patterns of small molecules in dogs’ blood were linked to longer or shorter lifespans in remarkably similar ways to those seen in people. These metabolic “fingerprints” could offer clues about the biological processes that drive aging, including metabolism, inflammation, and cellular stress.

Your sleep may be hiding an early clue to Alzheimer’s

What you eat before age 2 may affect your health 70 years later

Britain’s postwar sugar rationing created a rare natural experiment that let researchers examine how early sugar exposure might affect health decades later. People who experienced more rationing during their first 1,000 days had lower rates of several cancers and showed signs of slower biological aging. They were also still eating less sugar and maintaining healthier diets around age 50.

Short or long sleep was also associated with numerous conditions affecting the brain, heart, lungs, metabolism, and digestive system.

Scientists solve the mystery of a brain “switch” that can trigger weight loss in opposite ways

Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, while blocking it in the hypothalamus removed a kind of “brake” on fullness signals. The discovery helps explain why very different obesity drugs can achieve similar results and suggests that carefully combining GIP-targeting treatments with GLP-1 drugs like those related to Wegovy and Ozempic could produce stronger effects.

A major Alzheimer’s risk gene may shrink brain cells years before symptoms

Researchers have uncovered a possible reason why the Alzheimer’s risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking neurons and making memory circuits unusually active. That early hyperactivity predicted worse memory later in life. Reducing Nell2 in adult mice reversed the abnormal changes, raising hopes for a new way to intervene before Alzheimer’s progresses.

Alzheimer’s breakthrough: Scientists restore two hours of sleep without clearing brain plaques

Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged.

The common mistake that could make aging joints hurt more

Aging gradually wears down the cartilage and fluid that protect our joints, but avoiding movement may actually make matters worse. Exercise helps nourish cartilage, strengthens the muscles that protect joints, and can reduce osteoarthritis pain. Low-impact activities such as swimming, cycling, tai chi, yoga, and walking on varied terrain may also improve balance and mobility. Even a few minutes of the right kind of movement can make a difference.

Immune cells flood into the aging brain, Stanford scientists discover

Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the blood begin entering the brain as early as middle age, where they can transform into microglia, the brain’s specialized immune cells. The finding overturns a long-standing assumption that these cells remain largely separate from the body’s immune system throughout life.

Women who used estrogen-only hormone therapy later in life were less likely to develop dementia and showed fewer signs of Alzheimer’s disease in their brains, according to a large study of more than 21,000 participants. Hormone therapy use was linked to 39% lower odds of a dementia diagnosis and 35% lower odds of Alzheimer’s-related brain changes at autopsy, including amyloid plaques and tau tangles. Biomarker tests also suggested less amyloid buildup among hormone therapy users.

Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA.
