The boundaries of computing are shifting as biology fuses with technology. At the center of this new frontier is an emerging concept: a liquid computer powered by DNA. With the ability to support more than 100 billion unique circuits, this system could soon transform how we detect and diagnose disease.

While DNA is best known for encoding life, researchers are now exploring its potential as a computing tool. A team led by Dr. Fei Wang at Shanghai Jiao Tong University believes DNA can do much more than carry genetic instructions.

Their study, recently published in Nature, reveals how DNA molecules could become the core components of new computing systems. Rather than just holding genetic data, DNA could behave like wires, instructions, or even electrons inside biological circuits.

In 2025, China tech is no longer just catching up—it’s rewriting the rules. From quantum computers that outperform U.S. supercomputers to humanoid robots priced for mass adoption, China tech is accelerating at a pace few imagined. In this video, Top 10 Discoveries Official explores the 8 cutting-edge breakthroughs that prove China tech is reshaping transportation, AI, clean energy, and even brain-computer interfaces. While the West debates and regulates, China tech builds—from driverless taxis and flying cars to homegrown AI chips and thorium reactors. Watch now to understand why the future might not be written in Silicon Valley, but in Shenzhen.

Roughly 10 percent of the U.S. population is afflicted with major depressive disorder at any given time, and up to 20 percent will exhibit MDD symptoms over their lifetimes. Yet despite its prevalence, methods to treat MDD often fall short for a not-insignificant portion of the population. Antidepressants—the standard of treatment—don’t work for 30 percent with MDD.

When infused at a low dose, ketamine shows remarkable efficacy as a rapidly acting antidepressant, with effects observed within hours even in patients who have been resistant to other antidepressant treatments. However, consistent infusions of ketamine are needed to maintain symptoms at bay, which could result in side effects, such as dissociative behaviors and the possibility of addiction, and stopping treatment can result in relapse.

In a new study published in Science, Lisa Monteggia’s and Ege Kavalali’s labs show that it is feasible to substantially extend the efficacy of a single dose of ketamine from its current duration of up to a week to a longer period of up to two months.

The trumpets have sounded, the simulation hypothesis, the idea that we are all living in a simulation of our universe created by our distant descendants living in the “real” universe, is dead.

In a new paper, Italian physicist Franco Vazza, a researcher in astrophysics simulations, claims that it is impossible to simulate even a sizeable portion of the universe within itself.

This conclusion seems intuitively obvious. While the universe may be bigger on the inside, it doesn’t seem like you should be able to represent the whole thing inside itself.

The neocortex is highly susceptible to metabolic dysfunction. When exposed to global ischemia or anoxia, it suffers a slowly propagating wave of collective neuronal depolarization that ultimately impairs its structure and function. While the molecular signature of anoxic depolarization (AD) is well documented, little is known about the brain states that precede and follow AD onset. Here, by means of multisite extracellular local field potentials and intracellular recordings from identified pyramidal cells, we investigated the laminar expression of cortical activities induced by transient anoxia in rat primary somatosensory cortex. Soon after the interruption of brain oxygenation, we observed a well-organized sequence of stereotyped activity patterns across all cortical layers.
