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 / '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 ...

Phys.org / Quantum uncertainty captured in real time using femtosecond light pulses
Researchers from the University of Arizona, working with an international team, have captured and controlled quantum uncertainty in real time using ultrafast pulses of light. Their discovery, published in the journal Light: ...

Phys.org / From engines to nanochips: Physicists redefine how heat really moves
Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat spreads out smoothly, like water soaking through a sponge. That simple picture, written down by Joseph ...

Phys.org / How black holes produce powerful relativistic jets
A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered a strange jet protruding ...
