Phys.org / Pinning down the structure of quark-gluon plasma, the universe's first fluid
In the first fraction of a second following the Big Bang, matter existed as a trillion-degree plasma of quarks and gluons—subatomic particles that zinged around at close to the speed of light. This roiling soup lasted for ...
Phys.org / Fractal patterns reveal hidden limits to AI predictability
Researchers at the University of Sydney have identified a fundamental mathematical reason why artificial intelligence systems can learn different behaviors even when trained under almost identical conditions, a discovery ...
Phys.org / Webb Space Telescope's little red dots could hold key to first black holes
Johns Hopkins researchers searching the expanse of the universe for the existence of the first black holes are zeroing in on little red dots that may hold the key to the theoretical phenomenon.
Phys.org / When Einstein's gravitational waves meet Newton's tides
Newton's theory of gravity has described the tides accurately for centuries. But could a tiny trace of Einstein's general relativity also be hidden in them? In a new study, a mathematician at Freie Universität Berlin has ...
Phys.org / How do octopuses remember? Scientists uncover a surprising secret
How does an octopus remember what it has learned? A new study led by Dr. Ana Luiza Turchetti-Maia, Dr. Tal Shomrat and professor Binyamin (Benny) Hochner—researchers from the Hebrew University of Jerusalem and Ruppin Academic ...
Phys.org / Physicist develops detector capable of counting photons for quantum computing
Detecting a single photon is a challenge in itself. But what if you also want to know exactly how many photons arrive at a particular point at the same time? Physicist Erik Baalbergen is working on light detectors that can ...
Phys.org / New microscopy method reveals tiny cell structures and their molecular surroundings
How do cells respond to drugs? A new microscopy technique could provide more precise answers to this question in the future. Researchers from Bielefeld University and the University of Vienna have developed a method as part ...
Phys.org / Microbial growth in simulated Mars conditions could guide search for life
A new experiment reveals that Earth's microbes can grow in harsh conditions similar to what may exist just below the surface of Mars, suggesting new directions in the search for potential cellular life on the red planet.
Phys.org / Mystery origin of iconic Stonehenge Altar Stone deepens as search narrows
The hunt for the source of Stonehenge's mysterious Altar Stone has entered a new phase after scientists ruled out several previously proposed locations and moved a step closer to identifying its origins.
Phys.org / Plastic bags and bottles become industrial-strength adhesives through new upcycling method
Around 450 million metric tons of plastics are produced worldwide each year. The major share of this sheer volume is used only once and then winds up in an incinerator or in landfills. This also applies to so-called polyolefins, ...
Phys.org / Which infinity is bigger? Under alternative mathematical rules, a 2D map emerges
It is one of the great questions of mathematics: What does "infinity" actually mean? Which infinities are larger than others? Can infinities be arranged in a sequence, like the rungs of an endless ladder, so that for any ...
Phys.org / Coating made from renewable plant-based materials could simplify recycling while reducing exposure to microplastics
The lining in traditional disposable coffee cups can release plastic particles and be difficult to recycle, but a new plant-based coating can eliminate these issues with your morning brew.
