The Deadliest Age to Gain Weight
A new longitudinal study by Lund University found that gaining weight between ages 17 and 29 dramatically increases the chance of dying prematurely. Participants who added roughly 14 pounds during that period faced a 70% higher risk of early death compared with those who kept a stable weight. Even a modest average gain of about one pound per year translated into a 17% rise in mortality risk. The research, which followed more than 600,000 Swedes from 1963 to 2015, links early weight gain to later cardiovascular disease, type‑2 diabetes, digestive disorders and certain cancers.
Scientists in China Create a Predator-Like Material to Hunt for Uranium in the Ocean
An international team at China’s CAS Qinghai Institute of Salt Lakes has created a light‑powered metal‑organic framework micromotor that swims through water and selectively captures uranium ions. The 2‑micron particles propel themselves using hydrogen peroxide and double their speed under...
Toxins Plus Climate Harms Likely Cause of Reduced Fertility, Study Finds
A new peer‑reviewed review of 177 studies finds that simultaneous exposure to endocrine‑disrupting chemicals and climate‑change stressors creates additive or synergistic harms to fertility across invertebrates, wildlife and humans. The authors highlight chemicals such as PFAS, phthalates and microplastics, and...
Archaeologists Found 115,000-Year-Old Human Footprints Where They Shouldn’t Be
Archaeologists uncovered seven human footprints in a 115,000‑year‑old mudflat in Saudi Arabia’s Nefud Desert, representing the oldest known prints on the Arabian Peninsula. The prints were preserved in a rare, fine‑grained lakebed that prevented erosion for millennia. Researchers attribute the...
Letter to the Editor: Long Term Use of Proton Pump Inhibitors and Risk of Stomach Cancer: Population Based Case-Control Study...
A recent BMJ case‑control study across five Nordic countries reported no link between long‑term proton pump inhibitor (PPI) use and gastric non‑cardia adenocarcinoma. In a Letter to the Editor, Dr. Liping Kang challenges this conclusion, arguing that the study’s exposure...
A New Discovery at Easter Island Could Rewrite History As We Know It
A 2024 study led by University of Bologna archaeologist Silvia Ferarra dated one of Easter Island’s Rongorongo wooden tablets to 1493‑1509 CE, predating European contact. The finding suggests the Rapa Nui may have independently invented a writing system, a rarity in...
Discovery of a Novel Vulnerability in Aggressive Lymphoma Could Change Future Therapy
Researchers at the University of Cologne’s Center for Molecular Medicine have identified the protein cFLIP as a critical driver of resistance in diffuse large B‑cell lymphoma (DLBCL), especially the ABC subtype. By overexpressing cFLIP, lymphoma cells block both intrinsic and...
Smell Loss May Mark Alzheimer's Start as Olfactory Damage Map Comes Into Focus
Researchers at Daegu Gyeongbuk Institute of Science and Technology and Maastricht University have mapped, for the first time, the cellular mechanisms behind olfactory impairment in early Alzheimer’s disease. The study shows that toxic amyloid‑beta and phosphorylated tau accumulate sharply in...
‘Science Fiction’: How Life-Saving Organs Are Being Kept Alive Outside the Body
Organ shortages have driven a shift from static cold storage to active preservation methods. Normothermic machine perfusion (NMP) keeps kidneys and livers metabolically active in a nutrient‑rich, oxygenated circuit, extending viable time outside the body. An Australian first double transplant...
Letter to the Editor: Standard Chemoradiotherapy with Concurrent and Adjuvant Camrelizumab in Patients with High Risk Nasopharyngeal Carcinoma: Multicentre, Randomised,...
A phase‑3 BMJ trial showed that adding the PD‑1 inhibitor camrelizumab to concurrent chemoradiotherapy and 17 cycles of adjuvant maintenance extended progression‑free survival in high‑risk nasopharyngeal carcinoma, but overall survival did not improve significantly (HR 0.59, P = 0.19) after a median 39.9‑month...
India Plans Space Laboratories in Universities to Build Future Space Workforce
India will establish seven dedicated space laboratories across universities and colleges, giving students practical exposure to satellite and launch technologies. The move follows rapid expansion of the Indian space ecosystem, which has attracted more than $600 million in private investment and...

This ‘Longevity Vitamin’ Has Puzzled Scientists for 30 Years — Now They May Have Answers
Researchers have pinpointed the SLC35F2 gene as the transporter that moves queuosine—a bacteria‑derived, vitamin‑like compound—into human cells. Queuosine, abundant in fermented foods such as kefir, kimchi and tempeh, supports protein synthesis, brain function and may suppress cancer cells, earning it...
Scientists Believe Birds’ Skulls Hold Clues to Inner Lives of Long-Extinct Dinosaurs
Scientists are using modern bird skulls to infer the cognitive abilities of extinct dinosaurs such as Tyrannosaurus rex. Paleontologist Steve Brusatte and an international team propose that specific brain structures, identifiable in avian fossils, can predict behaviors like tool use,...
Machine Learning Predicts Asthma Risk in Children with Early-Life Atopic Dermatitis
Researchers at Kaiser Permanente Southern California used machine‑learning techniques on electronic health‑record data from 10,688 children diagnosed with atopic dermatitis before age three to predict later development of moderate‑to‑severe asthma and allergic rhinitis. The comprehensive asthma model achieved an AUC...
How Cognitive Ability and Logical Intuition Evolve During Middle and High School
Researchers at Université Paris Cité studied over 300 French middle and high school students to track the development of logical intuition. They found that 12‑year‑olds rely on slow, deliberate reasoning and do not improve with extra time, while 17‑year‑olds show...
