Worlds orbiting a sun-like star 100 light-years from Earth could unlock secrets surrounding the formation of our solar system.
To address the long-standing debate about whether a massive asteroid impact or volcanic activity caused the extinction of dinosaurs and numerous other species 66 million years ago, a team at Dartmouth College took an innovative approach — they removed scientists from the debate and let the computers decide.
The researchers report in the journal Science a new modeling method powered by interconnected processors that can work through reams of geological and climate data without human input. They tasked nearly 130 processors with analyzing the fossil record in reverse to pinpoint the events and conditions that led to the Cretaceous –Paleogene (K–Pg) extinction event that cleared the way for the ascendance of mammals, including the primates that would lead to early humans.
Summary: Researchers have discovered new insights into persistent aggression in female fruit flies, challenging existing theories.
A new study shows that certain neural cells sustain aggressive behavior for up to 10 minutes, suggesting factors beyond recurrent neural connections are at play.
These findings could aid understanding of human aggression and related neurological conditions, highlighting the need for revised models of aggression in the brain.
Optical wireless may no longer have any obstacles. A study by Politecnico di Milano, conducted together with Scuola Superiore Sant’Anna in Pisa, the University of Glasgow and Stanford University, and published in Nature Photonics, has made it possible to create photonic chips that mathematically calculate the optimal shape of light to best pass through any environment, even one that is unknown or changing over time.
The problem is well known: light is sensitive to any form of obstacle, even very small ones. Think, for example, of how we see objects when looking through a frosted window or simply when our glasses get foggy. The effect is quite similar on a beam of light carrying data streams in optical wireless systems: the information, while still present, is completely distorted and extremely difficult to retrieve.
The devices developed in this research are small silicon chips that serve as smart transceivers: working in pairs, they can automatically and independently ‘calculate’ what shape a beam of light needs to be in order to pass through a generic environment with maximum efficiency. And that’s not all: they can also generate multiple overlapping beams, each with its own shape, and direct them without them interfering with each other; in this way, the transmission capacity is significantly increased, just as required by next-generation wireless systems.
Summary: New research reveals the cerebellum’s significant role in the evolution of human cognitive functions. The study mapped the genetic development of cerebellar cells in humans, mice, and opossums, uncovering both ancestral and unique cellular characteristics.
Key findings include the increased proportion of specific Purkinje cells in humans, potentially linked to higher cognitive functions, and the identification of over 1,000 genes with varying activity profiles across species, some related to neurodevelopmental disorders.
Entanglement is a quantum phenomenon where the properties of two or more particles become interconnected in such a way that one cannot assign a definite state to each individual particle anymore. Rather, we have to consider all particles at once that share a certain state. The entanglement of the particles ultimately determines the properties of a material.
“Entanglement of many particles is the feature that makes the difference,” says Christian Kokail, one of the first authors of the paper published in Nature. “At the same time, however, it is very difficult to determine.”
The researchers led by Peter Zoller at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences (ÖAW) now provide a new approach that can significantly improve the study and understanding of entanglement in quantum materials.
When a biolab owned by several Chinese nationals was discovered in the small town of Reedley, California, there was outrage that such a thing was going on without officials knowing anything about it. Unfortunately, that was the least of what Americans should be outraged about. In this episode of China Uncensored, we look at the CDC and FBI’s unbelievable responses, why the substances in the biolab were never tested, and how similarly shady behavior by the US government in regards to Chinese biolabs should make every American fear for their life.
