Mutated stem cells known as leukemia stem cells (LSCs) initiate and fuel the development of acute myeloid leukemia (AML), an aggressive and usually fatal blood cancer.
Researchers at Albert Einstein College of Medicine describe a promising new strategy for treating and possibly curing acute myeloid leukemia by targeting leukem.
A SpaceX engineer details how the company is using a fleet of 9,000 lasers over the Starlink constellation to deliver high-speed internet across the globe.
The mission, dubbed NG-20, marks the first of three planned flights of Cygnus aboard a Falcon 9 rocket. Liftoff occurred at 12:07 p.m. EST (1707 UTC).
In 2022, researchers stumbled upon the footprint site near the northern tip of North Africa while examining boulders at a nearby pocket beach.
Scientists identified 18 new Tidal Disruption Events (TDEs), instances where a nearby black hole violently tears apart a neighboring star.
The powerful gravitational force of the black holes rips apart the star in its vicinity, resulting in a substantial release of energy across the entire electromagnetic spectrum.
The new catalog of TDEs was found by combing through the archival data of the satellite telescope NEOWISE. The team identified infrared patterns associated with these intense, transient bursts using a novel algorithm.
Epigenomic analyses suggest promising new approaches for monitoring and treating cancer. What are the analyses uncovering, and how close are they to improving patient outcomes?
University of Toronto Engineering researchers’ AI model designs proteins to deliver gene therapy ➡️
Researchers at the University of Toronto used an artificial intelligence framework to redesign a crucial protein involved in the delivery of gene therapy.
The study, published in Nature Machine Intelligence, describes new work optimizing proteins to mitigate immune responses, thereby improving the efficacy of gene therapy and reducing side effects.

But after a few billion years, something fishy begins to occur. Instead of approaching zero, the expansion rate starts to decrease at a slower rate than one would expect, and a distant galaxy’s recession speed doesn’t drop in the same fashion anymore. Once the Universe reaches an age that’s 7.8 billion years after the Big Bang, things start to get weird: these distant galaxies stop slowing down in their recession entirely, and appear to “coast” in the sense that they move away from us at a constant speed from moment-to-moment, as though the expansion had stopped decelerating.
And then, as the Universe continues to age, the recession speeds no longer remain constant, nor do they go back to decreasing. Instead, these distant galaxies appear to recede from us (and one another) more and more quickly. It’s as though some effect is causing the expansion to neither decelerate nor remain constant, but to actually increase and accelerate!
