Is Time a Quantum Illusion? Physicists propose it is not an underlying reality, reopening the debate about time and physics.
A new study found that some medications could have the unintended benefit of reducing dementia risk, while others could increase the risk. A doctor comments on the findings.
Porcine reproductive and respiratory syndrome virus (PRRSV) infection in pigs is economically devastating for the global swine industry. The viral infection leads to reproductive disorder in sows and respiratory problems in infected newborn and growing pigs.
Unfortunately, high genetic variability of the virus and differing disease-causing strength or virulence hinders vaccine development and complicates disease management. Not much is known about the factors contributing to viral disease severity or the anti-viral immune responses.
Dr. Jun-Mo Kim, Associate Professor at the Department of Animal Science and Technology, Chung-Ang University, Korea, has focused his research efforts on filling this gap in understanding.
Three books examine our complex and often fraught relationship with robots, AI, and automation.
Ubiquitously present in plant life, coumarins, as a class of phenolic compounds, have multiple applications—in everyday life, in organic synthesis, in medicine and many others. Coumarins are well known for their broad spectrum of physiological effects. The specific structure of the coumarin scaffold involves a conjugated system with excellent charge and electron transport properties. The antioxidant activity of natural coumarins has been a subject of intense study for at least two decades. Significant research into the antioxidant behavior of natural/semi-synthetic coumarins and their complexes has been carried out and published in scientific literature.

Clone Robotics made the Protoclone which is a faceless, anatomically accurate, synthetic human with over 200 degrees of freedom, over 1,000 Myofibers, and over 200 sensors.
Furthermore, healthcare and life sciences are both booming sectors with regards to artificial intelligence applications. Many other companies are also working at the intersection of technology and biology, given the numerous challenges that are present in the fields of drug discovery and protein folding. For example, Deepmind and Isomorphic Labs have made immense progress with AlphaFold, another leading foundation model ecosystem to better understand protein folding. Meta created something similar with its ESM Metagenomic Atlas. Given the increasing rates of catastrophic disease and the rapidly evolving nature of pathogens, scientists in these sectors hope to use the best of the advancements in AI to help solve some of biology’s toughest challenges.
Indeed, the immense progress that has been made thus far has paved the way for monumental scientific inventions and developments to emerge in the years ahead. Undoubtedly, this work is just getting started.
An international team has confirmed the discovery of a super-Earth orbiting in the habitable zone of a nearby sun-like star. The planet was originally detected two years ago by Oxford University scientist Dr. Michael Cretignier. This result, drawing on more than two decades of observations, opens a window to future studies of Earth-like exoplanets that may have conditions suitable for life.
The new planet, named HD 20,794D, has a mass six times that of Earth and orbits a star similar to our sun, located just 20 light years away. Its orbit places it within the habitable zone of the system, meaning it is at the right distance from its star to sustain liquid water on its surface, a key ingredient for life as we know it. The paper is published in the journal Astronomy & Astrophysics.
Dr. Cretignier first identified a candidate exoplanet signal in 2022, while analyzing archived data recorded by the HARPS (High Accuracy Radial Velocity Planet Searcher) spectrograph at the La Silla Observatory in Chile. This data analyzes the light absorbed and emitted by objects.
