But thanks to AI-powered genetic research, scientists have revealed a far more entangled history. Modern humans and Neanderthals didn’t just cross paths; they repeatedly interbred, shared genes, and even merged populations over nearly 250,000 years. These revelations suggest that Neanderthals never truly disappeared — they were absorbed. Their legacy lives on in our DNA, reshaping our understanding of what it means to be human.

Scientists had zeroed in on a part of the virus called the NiRAN domain, believed to be a powerful target for new antiviral drugs. But when a Rockefeller team revisited a highly cited 2022 study, they found the evidence didn’t hold up. Key molecules shown in the original virus model were actually missing. Their discovery could help prevent wasted time and resources in the race to develop better treatments—and highlights how even one bad blueprint can throw off years of research. Fri, 04 Jul 2025 08:28:05 EDT https://www.sciencedaily.com/releases/2025/07/250704032925.htm https://www.sciencedaily.com/releases/2025/07/250704032922.htm Scientists have discovered that the bacteria behind Lyme disease and anaplasmosis have a sneaky way of surviving inside ticks—they hijack the tick’s own cell functions to steal cholesterol they need to grow. By tapping into a built-in protein pathway, the bacteria keep themselves alive until they can infect a new host. The research opens the door to new methods of stopping these diseases before ticks ever get the chance to bite. A new web tool also reveals that this trick might be used by other blood-feeding bugs too.

Japanese researchers found that benzaldehyde can stop the shape-shifting ability of aggressive cancer cells, which lets them dodge treatments and spread. By targeting a specific protein interaction essential for cancer survival—without harming normal cells—benzaldehyde and its derivatives could form the basis of powerful new therapies, especially when combined with existing radiation or targeted treatments.

A groundbreaking study tracking over 500 women aged 35 to 55 reveals that anger traits like outbursts and hostility tend to diminish with age and menopause progression. This shift could signal enhanced emotional regulation during and after the reproductive transition. Surprisingly, the only form of anger that remained steady was suppressed anger.

Researchers used a virus to deliver a healthy copy of the OTOF gene into the inner ear, improving auditory function across all ten participants in the study. The therapy worked best in young children but still benefited adults, with one 7-year-old girl regaining almost full hearing. Even more exciting: this is just the start, as scientists now aim to target other genes that cause more common forms of deafness.

Unlike previous materials, this new 3D-printed aerogel maintains its efficiency at larger sizes, solving a key scalability issue. In outdoor tests, it produced clean water directly from the ocean without any electricity, pointing to a future of low-cost, energy-free freshwater production.

The change affects a protein used by immune cells to kill tumors—except in humans, it’s vulnerable to being shut down by an enzyme that tumors release. This flaw may be one reason treatments like CAR-T don’t work as well on solid tumors. The surprising twist? That mutation might have helped our brains grow larger over time. Now, researchers are exploring ways to block the enzyme and give our immune system its power back.

Legacy toxins like triclosan are slowly declining, yet replacements such as DINCH plasticizer and modern pesticides are rising. Toddlers—especially the youngest, later-born, and those from minority groups—often carried higher levels than their own mothers. Scientists urge expanded biomonitoring and stricter regulations before these invisible pollutants derail early development.

A large national study found that more adolescents are vaping THC, CBD, and especially synthetic cannabinoids, which are often unregulated and far more dangerous. Even more troubling, many teens don’t know what’s in their vape pens at all. Researchers also found that girls are now more likely than boys to vape these substances. As these mysterious and risky chemicals gain popularity, scientists are sounding the alarm about the urgent need for better education, regulation, and awareness.

Cornell psychologist Daniel Casasanto’s team sifted nearly a thousand studies, ultimately finding no consistent advantage for lefties on standard divergent-thinking tests—and even a slight edge for right-handers in some. The myth appears to thrive on coincidence: left-handedness is rare and so is creative genius, plus lefties’ overrepresentation in art and music gets cherry-picked while other professions are ignored.

They discovered early signs of rejection within 10 days and pinpointed key immune players—like macrophages—driving the response. Even more exciting: when targeted therapies were applied, the immune assault weakened. As U.S. clinical trials of pig kidney transplants begin, this breakthrough offers hope for overcoming the immune barrier that has long stood in the way of xenotransplantation.
