Beneath the beauty of coral reefs lies a hidden universe of microbes unlike anything scientists expected. Each coral species supports its own specialized microbial partners, many of which have never been studied before. These microbes produce a stunning variety of chemical compounds with potential uses in medicine and biotech. The discovery highlights just how much is at stake as coral reefs face growing threats.

State Department would send PEPFAR money directly to countries, which could then pay fees to health agency for help

Katherine Yelick will become director of the Department of Energy’s Lawrence Berkeley National Laboratory on 1 July

Many cancer patients turn to biotin supplements hoping to restore hair lost during treatment, but experts warn the popular vitamin may do more harm than good. While biotin is often marketed for stronger hair and nails, there’s little evidence it actually helps cancer-related hair loss—and it can dangerously interfere with lab tests. Doctors say the supplement can distort key blood markers, potentially masking cancer recurrence or delaying treatment decisions.

A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation. Unlike many antivirals that target just one part of the virus, these natural compounds act in several ways at once, potentially making it harder for resistance to develop.

Integrity conference attendees debated when and how authors should declare AI use in papers

Eating eggs might do more than just start your day—it could help protect your brain. Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer’s disease, with daily or near-daily consumption linked to up to a 27% reduction. Even modest egg intake showed benefits, suggesting that small dietary changes could make a meaningful difference over time.

Small study that prioritized Black and low-income participants yields “remarkable” results

Researchers have created a next-generation obesity drug that works like a “Trojan horse,” using GLP-1/GIP signals to slip a powerful metabolic enhancer directly into target cells. In mice, it outperformed existing treatments—curbing appetite, increasing weight loss, and improving blood sugar levels. Because the extra drug acts only where it’s needed, it can be used at much lower doses, potentially reducing side effects.

Some people taking Ozempic-like diabetes drugs may be getting dramatically better results for a surprising reason: why they overeat in the first place. A year-long study in Japan found that people who tend to eat because tempting food looks or smells irresistible were much more likely to lose weight and improve blood sugar levels on GLP-1 medications. But people who eat mainly in response to stress, sadness, or emotional struggles didn’t see the same long-term benefits.

The ε4 allele of apolipoprotein E (APOE4) is the strongest genetic risk factor for sporadic Alzheimer's disease (AD) and exacerbates AD-related pathologies. Identifying strategies to mitigate the pathogenic effects of APOE4 remains a critical challenge in the field of AD research. The rare APOE3 Christchurch (APOE3Ch) variant has been suggested to be potentially protective against AD. Our study investigated whether hepatic expression of APOE3Ch could mitigate APOE4-associated AD pathologies. We...

Neurogenesis is the process by which new neurons are generated from neural stem cells (NSCs) and neural progenitor cells (NPCs). Impairment in this process can lead to cognitive and memory deficits, among other issues. Research indicates that defective neurogenesis is closely associated with neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). These conditions not only affect a significant global population but also exert profound...
