Medical Xpress / Specialized neuron populations in the mouse cortex coordinate to guide correct decisions, study suggests
For decades, neuroscientists have been trying to pinpoint the neural underpinnings of behavior and decision-making. Past studies suggest that specialized groups of neurons in the mammalian brain, particularly in the cortex, ...
Phys.org / Experimental proof shows quantum world is even stranger than previously thought
The quantum world is famously weird—a single particle can be in two places at once, its properties are undefined until they are measured, and the very act of measuring a quantum system changes everything. But according ...
Phys.org / Electric discharges detected on Mars for the first time
On Mars, winds constantly stir up whirlwinds of fine dust. It was at the center of two of these dust devils that the SuperCam instrument's microphone, the first ever to operate on Mars, accidentally recorded particularly ...
Phys.org / The collapse of Maya civilization: Drought doesn't explain everything
Between 750 and 900 CE, the population of the Maya lowlands in Central America experienced a major demographic and political decline which, according to the scientific literature, coincided with repeated episodes of intense ...
Phys.org / Plastic pollution is worsened by warming climate and must be stemmed, researchers warn
Climate change conditions turn plastics into more mobile, persistent, and hazardous pollutants. This is done by speeding up plastic breakdown into microplastics—microscopic fragments of plastic—spreading them considerable ...
Phys.org / 5 reasons the COP30 climate conference failed to deliver on its 'people's summit' promise
As the sun set on the Amazon, the promise of a "people's Cop" faded with it. The latest UN climate summit—known as Cop30, hosted in the Brazilian city of Belém—came with the usual geopolitics and the added excitement ...
Phys.org / Archaeologists discover solitary grave from ancient Kingdom of Kerma in remote Bayuda Desert
Dr. Monika Badura and her colleagues have published a study analyzing an isolated burial found in the Bayuda Desert in the journal Azania: Archaeological Research in Africa. The discovery, made at site BP937 in Sudan, has ...
Phys.org / The body's molecular mail revealed: Scientists decode blood's hidden messengers
Every second, trillions of tiny parcels travel through your bloodstream—carrying vital information between your body's cells. Now, scientists at the Baker Heart and Diabetes Institute have opened this molecular mail for ...
Phys.org / Domestic cats came from North Africa to Europe only 2,000 years ago, DNA evidence suggests
Despite the ubiquity of cats in modern homes, we still don't know many details about the timing and routes of early cat domestication and dispersal into Europe and beyond, aside from the common association of cats with ancient ...
Phys.org / Rapid X-ray pulses enable 100-fold efficiency boost for photoionization
Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a short-lived window of opportunity opens. For just a few femtoseconds, before an electron fills the void ...
Phys.org / Quantum sensor based on silicon carbide qubits operates at room temperature
Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors, devices that rely on ...
Medical Xpress / Tirzepatide's benefits fade for most: Weight and health markers rebound after withdrawal, study finds
Eli Lilly and Company, along with partner institutions in the US and United Kingdom, describe how short-term pharmacologic intervention does not appear to have lasting effects for most tirzepatide patients. People with obesity ...
