Phys.org / Industry scientists reveal reluctance to test chemicals for behavioral effects, despite growing evidence
An international study led by the University of Portsmouth has revealed reluctance from industry scientists to test chemicals for their effects on human and wildlife behavior, despite growing evidence linking environmental ...
Phys.org / Enzyme pair unlocks a microbial puzzle to better treat, prevent and detect disease
Many medications and other therapeutic agents, including antibiotics and cancer therapies, must enter cells to reach their targets to have their effect. But that can pose a challenge, as drugs often have difficulty crossing ...
Phys.org / Efficient bacterial modeling cuts computational costs for researchers
Newcastle scientists have developed an efficient new model to track bacterial responses to toxic chemicals and nutrients.
Phys.org / Climate change may create 'ecological trap' for species who can't adapt
Even as autumn days grow shorter, a warming climate means Ohio winters aren't as cold as they were just a few decades ago, according to National Oceanic and Atmospheric Administration data. This increasing mismatch between ...
Phys.org / 'Toothpick grooves' in ancient fossil human teeth may not be from toothpicks after all
For decades, small grooves on ancient human teeth were thought to be evidence of deliberate tool use—people cleaning their teeth with sticks or fibers, or easing gum pain with makeshift "toothpicks." Some researchers even ...
Phys.org / Clam shells sound alarm over unstable North Atlantic currents
Bivalves, such as clams, oysters and mussels, record seasonal environmental changes in their shells, making them living chronicles of climate history. A new study of bivalve shells has detected two major episodes of instability ...
Phys.org / How biological motors achieve maximum efficiency
Inside nearly every cell of your body, the tiny F1 motor works non-stop to create adenosine triphosphate (ATP), the universal energy source that powers almost every action you take—from breathing to running. While scientists ...
Phys.org / Strontium optical lattice clock exhibits record-high coherence time
Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct quantum states at a particular ...
Phys.org / VERITAS observations explore a unique microquasar
Using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), German astronomers have observed a unique microquasar known as SS 433. Results of the observational campaign, published Sept. 25 on the arXiv pre-print ...
Phys.org / AI tool visually maps science funding and its real-world impacts
The impact of scientific research extends far beyond the laboratory. Breakthroughs like insulin and innovations like the internet have transformed our everyday lives. They also influence policymaking and the overall economy. ...
Phys.org / New species of deep-sea shark and crab discovered off Western Australia
Researchers have described a new species of deep-sea lanternshark and crab, both with the help of specimens collected from a CSIRO-led 2022 voyage of CSIRO research vessel (RV) Investigator.
Phys.org / Researchers unearth origins of Ancient Egypt's Karnak Temple
Researchers have carried out the most comprehensive geoarchaeological survey of Egypt's Karnak Temple near Luxor—one of the ancient world's largest temple complexes and a UNESCO World Heritage site welcoming millions of ...
