Phys.org / Visual system of butterflies changes with seasons, research reveals
The shift from warm summer to cool fall conditions can be stressful for many animals. Surviving each season requires a multitude of different physiological and behavioral traits that scientists are still working to understand.
Medical Xpress / America doesn't have enough hospital beds. This could help
Every day, across the nation, patients wait hours or days in emergency departments until a bed opens up for them in the hospital.
Phys.org / The microbiome of an entire country mapped for the first time
An international research team led by Aalborg University with contributions from the University of Vienna has systematically mapped the microbiome of an entire country for the first time. In the study "Microflora Danica," ...
Phys.org / Fearless frogs feast on deadly hornets
A remarkable resistance to venom has been discovered in a frog that feasts on hornets despite their deadly stingers. This frog could potentially serve as a model organism for studies on mechanisms underlying venom tolerance.
Medical Xpress / PFAS exposure may limit improvements in blood sugar after bariatric surgery
A new USC study shows teens with higher blood levels of per- and polyfluoroalkyl substances (PFAS) measured before bariatric surgery had smaller improvements in blood sugar over five years, including fasting glucose and hemoglobin ...
Medical Xpress / Single enzyme failure found to drive neuron loss in dementia
Researchers at Helmholtz Munich, the Technical University of Munich and the LMU University Hospital Munich uncovered a mechanism that protects nerve cells from premature cell death, known as ferroptosis. The study provides ...
Phys.org / LHC data confirm validity of new model of hadron production—and test foundations of quantum mechanics
A boiling sea of quarks and gluons, including virtual ones—this is how we can imagine the main phase of high-energy proton collisions. It would seem that particles here have significantly more opportunities to evolve than ...
Medical Xpress / Order of cancer-driving mutations affects the chance of tumor development, study shows
The order of cancer-driving mutations—genetic changes—plays an important role in whether tumors in the intestine can develop, new research reveals.
Medical Xpress / Ultra-processed foods: Leading cause of 'chronic disease pandemic,' scientists warn
Ultra-processed foods (UPFs) are a leading cause of the "chronic disease pandemic" linked to diet, with food firms putting profit above all else, global experts have warned.

Researchers in China report that global incidence rates of psoriasis rose slightly from 1990 to 2021 and are projected to continue rising for both men and women through 2050.
Phys.org / 'We gotta act white': How voice recognition tech fails for Aboriginal English speakers
More and more phones, televisions, smart speakers, and cars are embedded with automated speech-recognition technologies that transcribe speech into written words. These technologies enable the devices to understand what songs ...
Medical Xpress / From field to lab: Study reveals how people with vision loss judge approaching vehicles
Patricia DeLucia has spent decades studying something many of us never think about: judgments about collisions that are crucial for safety. But the roots of her research stretch back to her childhood, long before she became ...
