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 to dopamine.

Wireless charging has become one of those small but satisfying conveniences of modern smartphones. You drop your device on a pad and watch the battery percentage climb without fiddling with cables or ports. Yet for many users, that effortless charge doesn’t always come at the speed they expect.

Researchers found that tau proteins don’t jump straight into forming Alzheimer’s-associated fibrils—first they assemble into soft, reversible clusters. When the clusters were dissolved, fibril growth was almost entirely suppressed. This reveals a promising new strategy: stop the precursors, stop the disease. Read more ›

Rutgers scientists found that metformin can blunt many of the metabolic and cardiovascular improvements normally produced by exercise. Participants who took the drug saw reduced gains in fitness, blood vessel function, and glucose control. The interference may stem from how metformin affects mitochondrial activity. Read more ›

Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how they might be harnessed for advanced quantum technologies. Read more ›

Scientists discovered that alcohol activates a sugar-producing pathway in the body, creating fructose that may reinforce addictive drinking. The enzyme responsible, KHK, appears to drive both alcohol cravings and liver injury. When this enzyme was blocked in mice, their drinking decreased and their livers showed far less damage.

Scientists found that people who use both cannabis and tobacco show a distinct brain pattern tied to mood and stress regulation. Their scans revealed higher levels of an enzyme that reduces a natural feel-good molecule in the brain. This imbalance may help explain why co-users experience more anxiety and struggle more when quitting. Read more ›

Neuroimaging shows that the brain shifts into reward or risk mode depending on whether the context involves a gain or a loss. Friends show synchronized brain activity that can predict successful deception. Social bonds and incentives can subtly warp how we judge honesty. Read more ›

Ultra-processed foods, already known for their links to health problems in adults, are now shown to harm young adults too, disrupting blood sugar regulation long before illness appears. A four-year USC study following 85 participants found that even modest increases in UPF consumption drove up the risk of prediabetes and insulin resistance, two early markers that pave the way for type 2 diabetes.
