Researchers have created the first comprehensive genetic blueprint of freshly isolated human immune cells—B cells, T cells, monocytes, and mast cells—without the distortions caused by lab culture. The detailed atlas could accelerate drug development for immunotherapies, vaccines, and treatments for autoimmune diseases by giving companies a clearer picture of how these cells actually function in the body.EN

Researchers found that humans carry a broken version of a gene transporter that still works in apes and likely regulates sex hormones. A single mutation that occurred in our ancestors disabled SLC22A10, potentially reshaping how human bodies manage steroid hormones—with implications for understanding reproductive biology and developing hormone-related therapies.EN

A new study reveals that eliminating germline tissue—which produces sperm and eggs—extends lifespan in male nematodes but offers no survival benefit to females. The finding challenges assumptions about aging and reproduction, suggesting that sex-specific biology demands different approaches to longevity research and may influence future strategies in regenerative medicine and aging therapeutics.EN

Researchers have decoded how two proteins ferry genetic instructions to the mitochondria's protein-making factories, revealing the mechanism cells use to regulate energy production. The discovery could unlock new therapeutic targets for genetic diseases and age-related conditions tied to mitochondrial dysfunction, opening possibilities for treatments affecting millions of patients.EN

Researchers analyzing over 1 million people have identified 2,103 genetic variants that predict hypertension risk with unprecedented accuracy. The findings could reshape clinical screening and drug development for a disease affecting 1.3 billion people globally, potentially reducing strokes, heart attacks, and healthcare costs.EN

A major new analysis finds that infant eye-tracking behaviors long used as early autism markers actually reflect separate genetic pathways unrelated to autism risk. The finding could reshape how researchers and clinicians interpret social attention patterns in young children, affecting screening protocols and intervention strategies worth billions in early-care spending.EN

Researchers have identified how Miro proteins control the movement of mitochondria through cells—a process that breaks down in neurodegenerative diseases. The findings could point toward new drug targets for Parkinson's and Alzheimer's, conditions affecting millions globally and representing a major pharmaceutical development opportunity.EN

Researchers have identified the molecular mechanism that allows seeds to survive in dormancy for thousands of years—a discovery that could transform agricultural seed banking and crop resilience. The finding reveals how specific proteins regulate the cellular machinery seeds use to maintain their viability, opening paths to breed crops that stay viable longer and adapt to climate pressures.EN

A comprehensive review of China's antimicrobial resistance policies reveals critical gaps in enforcement and environmental oversight, threatening public health and business continuity across sectors. Researchers identified 44 policy documents but found weak accountability mechanisms and insufficient coordination—problems that could undermine efforts to contain drug-resistant infections across healthcare, agriculture, and environmental systems.EN

Researchers discovered that a Y chromosome crossed from one African primate species to another millions of years after they diverged—a finding that challenges conventional evolutionary theory about genetic barriers between species. The work could reshape understanding of how evolution works and inform conservation strategies for endangered primates facing hybridization pressures.EN

Neuroscientists have developed a method to simultaneously capture brain activity using both non-invasive and invasive sensors, offering unprecedented insight into how the brain works. The advance could accelerate drug development, improve epilepsy treatment, and help companies and regulators understand neurological conditions more effectively.EN

Researchers found that blocking a brain enzyme called IRAP boosts production of proteins essential for learning and memory in rat neurons. The discovery could accelerate development of cognitive-enhancing drugs for Alzheimer's, dementia, and age-related memory decline—a multibillion-dollar market opportunity as populations age globally.EN

Researchers have identified how giant mobile DNA elements called Starships enable fungi to rapidly acquire and share useful genes across species barriers—a process that occurs naturally but could inform biotech applications and disease management. The findings reveal that evolution operates faster than previously understood, with implications for predicting how organisms adapt to environmental pressures.EN

Researchers have identified a 450-million-year-old brachiopod species across three continents, suggesting marine life recovered and dispersed faster than previously thought after environmental upheaval.
