An anonymous reader quotes a report from Reuters: Researchers said on Wednesday they have discovered that parts of the brain region called the motor cortex that govern body movement are connected with a network involved in thinking, planning, mental arousal, pain, and control of internal organs, as well as functions such as blood pressure and Read more about Scientists Identify Mind-Body Nexus In Human Brain[…]
A survey of plastic waste picked up in the North Pacific Subtropical Gyre—aka the Giant Pacific Garbage Patch—has revealed that the garbage is providing a home to species that would otherwise not be found in the deep ocean. Over two-thirds of the trash examined plays host to coastal marine species, many of which are clearly Read more about Pacific garbage patch providing a deep ocean home for coastal species[…]

Scientists using data from the Atacama Cosmology Telescope in Chile have made a detailed map of dark matter’s distribution across a quarter of the sky. The map shows regions the distribution of mass extending essentially as far we can see back in time; it uses the cosmic microwave background as a backdrop for the dark Read more about New Map of Dark Matter Supports Einstein’s Theory of Gravity[…]
Researchers have discovered that in the exotic conditions of the early universe, waves of gravity may have shaken space-time so hard that they spontaneously created radiation. […] a team of researchers have discovered that an exotic form of parametric resonance may have even occurred in the extremely early universe. Perhaps the most dramatic event to Read more about Physicists Discover that Gravity Can Create Light[…]
The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics. The original double-slit experiment, performed in 1801 by Thomas Young at the Royal Institution, showed that light acts as a wave. Further experiments, however, showed Read more about Double-slit experiment done using time instead of space[…]
What does a stressed plant sound like? A bit like bubble-wrap being popped. Researchers in Israel report in the journal Cell on March 30 that tomato and tobacco plants that are stressed—from dehydration or having their stems severed—emit sounds that are comparable in volume to normal human conversation. The frequency of these noises is too Read more about Stressed plants emit airborne sounds that can be detected from more than a meter away[…]
A mammoth meatball has been created by a cultivated meat company, resurrecting the flesh of the long-extinct animals. The project aims to demonstrate the potential of meat grown from cells, without the slaughter of animals, and to highlight the link between large-scale livestock production and the destruction of wildlife and the climate crisis. The mammoth Read more about Meatball from long-extinct mammoth created by food firm[…]
Computer scientists found the holy grail of tiles. They call it the “einstein,” one shape that alone can cover a plane without ever repeating a pattern. And all it takes for this special shape is 13 sides. In the world of mathematics, an “aperiodic monotile”—also known as an einstein based off a German phrase for Read more about 13-Sided Shape That never repeats discovered[…]
The number of exploding stars (supernovae) has significantly influenced marine life’s biodiversity during the last 500 million years. This is the essence of a new study published in Ecology and Evolution by Henrik Svensmark, DTU space. Extensive studies of the fossil record have shown that the diversity of life forms has varied significantly over Read more about A persistent influence of supernovae on biodiversity[…]
[…] The invention, by a University of Bristol physicist, who gave it the name “counterportation,” provides the first-ever practical blueprint for creating in the lab a wormhole that verifiably bridges space, as a probe into the inner workings of the universe. By deploying a novel computing scheme, revealed in the journal Quantum Science and Technology, Read more about ‘Counterportation’: Quantum breakthrough paves way for world-first experimental wormhole[…]
[…] “The image was captured on a summer evening in São José dos Campos [in São Paulo state] while a negatively charged lightning bolt was nearing the ground at 370 km per second. When it was a few dozen meters from ground level, lightning rods and tall objects on the tops of nearby buildings produced Read more about Unique image obtained by scientists with high-speed camera shows how lightning rods work[…]
[…] An interdisciplinary team of scientists have released a complete reconstruction and analysis of a larval fruit fly’s brain, published Thursday in the journal Science. The resulting map, or connectome, as its called in neuroscience, includes each one of the 3,016 neurons and 548,000 of the synapses running between neurons that make up the baby Read more about First Complete Map of a Fly Brain Has Uncanny Similarities to AI Neural Networks[…]
Drop a flat piece of paper and it will flutter and tumble through the air as it falls, but a well-fashioned paper airplane will glide smoothly. Although these structures look simple, their aerodynamics are surprisingly complex. Researchers at New York University’s Courant Institute of Mathematical Sciences conducted a series of experiments involving paper airplanes to Read more about Experiments with paper airplanes reveal surprisingly complex aerodynamics[…]
Geology textbooks almost inevitably include a cutaway diagram of the Earth showing four neatly delineated layers: a thin outer shell of rock that we live on known as the crust; the mantle, where rocks flow like an extremely viscous liquid, driving the movement of continents and the lifting of mountains; a liquid outer core of Read more about Does the Earth’s core have an innermost core?[…]
Think of bringing a pot of water to the boil: As the temperature reaches the boiling point, bubbles form in the water, burst and evaporate as the water boils. This continues until there is no more water changing phase from liquid to steam. This is roughly the idea of what happened in the very early Read more about The bubbling universe: A previously unknown phase transition in the early universe resolves Hubble (constant) tension[…]
Eight years ago, a patient lost her power of speech because of ALS, or Lou Gehrig’s disease, which causes progressive paralysis. She can still make sounds, but her words have become unintelligible, leaving her reliant on a writing board or iPad to communicate. Now, after volunteering to receive a brain implant, the woman has been Read more about An ALS patient set a record communicating through a brain implant: 62 words per minute[…]
[…]In a study published Monday in the journal Biosensor and Bioelectronics, a group of researchers from Tel Aviv University (via Neuroscience News) said they recently created a robot that can identify a handful of smells with 10,000 times more sensitivity than some specialized electronics.
