Quasars represent some of the most luminous and energetic phenomena in the universe. These distant powerhouses are driven by supermassive black holesâcolossal gravitational engines with masses millions to billions of times that of our sunâwhich actively devour surrounding matter at incredible rates.
As gas, dust, and stellar material spiral inward through an accretion disk superheated to millions of degrees, this matter releases tremendous energy across the electromagnetic spectrum before crossing the event horizon. The resulting emissions can outshine entire galaxies despite originating from a region no larger than our solar system.
The discovery of billion-solar-mass black holes in distant quasars challenges conventional growth models in astrophysics. Scientists have observed these supermassive black holes (SMBHs) at redshifts beyond zâł6, when the universe was less than a billion years oldâtheoretically insufficient time for them to reach such enormous masses through standard Eddington-limited accretion from stellar-mass seeds.
Tempted to skip the floss? Your heart might thank you if you donât. A new study from Hiroshima University (HU) finds that the gum disease bacterium Porphyromonas gingivalis (P. gingivalis) can slip into the bloodstream and infiltrate the heart. There, it quietly drives scar tissue buildupâknown as fibrosisâdistorting the heartâs architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).
Clinicians have long noticed that people with periodontitis, a common form of gum disease, seem more prone to cardiovascular problems. One recent meta-analysis has linked it to a 30% higher risk of developing AFib, a potentially serious heart rhythm disorder that can lead to stroke, heart failure, and other life-threatening complications.
Globally, AFib cases have nearly doubled in under a decade, rising from 33.5 million in 2010 to roughly 60 million by 2019. Now, scientific curiosity is mounting about how gum disease might be contributing to that surge.
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 upâitâs 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 buildsâfrom 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.

CRISPR-TO, a system for programmable control of spatial localization of cellular RNAs, is presented and enables functional investigation of endogenous RNA localization in diverse living cells.
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. Antidepressantsâthe standard of treatmentâdonât 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 Monteggiaâs and Ege Kavalaliâs 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 ârealâ 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 doesnât 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.
