Phys.org / DNA floating in seawater is now enough to let scientists monitor the health of America's dolphin populations
DNA is everywhere in the world's oceans—not only packaged inside cells from skin, scales, mucus, feces, and blood, but also floating freely. Sequencing such "environmental DNA" (eDNA) from open water has long been used as ...
Phys.org / 370 billion crickets are farmed for food every year. Scientists have discovered they may feel pain
You're cooking dinner, distracted, and your hand brushes a hot pan. Nerve signals race to your spinal cord and back to yank your arm away in a fraction of a second, with no thought required.
Medical Xpress / Human health appears unaffected by living near wind turbines
High-resolution data collected across the United States show negligible evidence of adverse health outcomes tied to wind turbine exposure, a study finds. Despite helping to reduce greenhouse gas emissions, wind turbine installations ...
Phys.org / New field evidence from Canada shows old wells can leave a hidden leakage footprint
Old oil and gas wells may continue to affect the environment long after they have stopped producing, with new field evidence showing that their leakage footprint can be broader and more persistent than surface methane measurements ...
Medical Xpress / Common asthma drug may turn off tumor 'switch' tied to immunotherapy resistance
A drug widely used to treat asthma and allergies may also help fight aggressive cancers, reports a new Northwestern Medicine study that uncovered how tumors hijack common white blood cells to evade immunotherapy.
Phys.org / A smelly dog breath breakthrough: Plant-based spray tackles odor and harmful oral microbes
Pet owners love their dogs but may not always love the smell of their breath. Because this bad odor can signal oral disease, veterinary clinics will prescribe daily toothbrushing, antibiotics, or chemical rinses as treatment. ...
Phys.org / Seaweed study unlocks surprising solution for cattle nutrition and sustainable agriculture
Cows eat grass...everyone knows that. But climate change is forcing producers and scientists to rethink some of our long-held assumptions about livestock nutrition. Crop costs are climbing. Traditional pastures are under ...
Phys.org / Plasma treatment keeps cut flowers fresher for two weeks without chemicals
From long‑distance transport to chemical preservatives, most cut flowers come with a hidden environmental cost—something a new Griffith University experiment aims to rethink.
Medical Xpress / Blood test spots failing prostate cancer treatment within 6-12 weeks, study finds
A new blood test could help doctors identify whether a treatment for advanced prostate cancer is failing weeks earlier than current tests, according to a U.K.-wide study led by UCL researchers. The study, published in Nature ...
Medical Xpress / How medical education can revive the physician–scientist pipeline
The physician–scientist has long occupied a unique place in medicine—bridging the laboratory and the clinic, translating scientific discoveries into innovative patient care. But that role is becoming increasingly rare. The ...
Phys.org / You are what you eat: Cichlid fish reveal how food sources drive evolution of digestive system
Different beak and jaw shapes are illustrative examples of how animal species have adapted to different food sources. In a new study published in the journal Nature, researchers now show how diet itself shapes the composition ...
Phys.org / We analyzed the TikTok history of 142 men. Here's what it taught us about the manosphere
Interest in the manosphere has recently surged yet again, with the recent Louis Theroux documentary catapulting the term "manosphere" back to the forefront of our cultural psyche.
