Observations of the cosmic microwave background, leftover light from when the Universe was only 380,000 years old, reveal that our cosmos is not rotating. Infinitely long cylinders don’t exist. The interiors of black holes throw up singularities, telling us that the math of GR is breaking down and can’t be trusted. And wormholes? They’re frighteningly unstable. A single photon passing down the throat of a wormhole will cause it to collapse faster than the speed of light. Attempts to stabilize wormholes require exotic matter (as in, matter with negative mass, which isn’t a thing), and so their existence is just as debatable as time travel itself.

This is the point where physicists get antsy. General relativity is telling us exactly where time travel into the past can be allowed. But every single example runs into other issues that have nothing to do with the math of GR. There is no consistency, no coherence among all these smackdowns. It’s just one random rule over here, and another random fact over there, none of them related to either GR or each other.

If the inability to time travel were a fundamental part of our Universe, you’d expect equally fundamental physics behind that rule. Yet every time we discover a CTC in general relativity, we find some reason it’s im possible (or at the very least, implausible), and the reason seems ad hoc. There isn’t anything tying together any of the “no time travel for you” explanations.

Scientists detect two giant black holes flashing light a billion light-years away.

Astronomers have identified two giant black holes causing strange flashes of light at about one billion light years away from Earth. The flashes or light bursts are occurring at regular intervals, but what’s causing them is even more surprising.

The researchers suggest that the black hole pair is swirling within a vast cloud of gas, and their interaction with the gas cloud is actually sparking the unusual flashes —- marking it as the first observation of its kind.

Scientists 3D-print EPLM using bioink and living cells.

Using a 3D printer and a bioink, scientists create an “engineered plant living material” (EPLM) that harnesses the power of cells.

Two developments in 2025 will mark a decisive shift in the decades-old quest to generate cheap and abundant energy from nuclear fusion.

A near four-decade quest to bring the quagga back is being heralded as a success, but not everyone is impressed.

Bioelectronics research and development of implants made of electrically conductive materials for disease treatment is advancing rapidly. However, bioelectronic treatment is not without complications. Researchers at Lund University in Sweden have taken another step forward by developing a refined method to create detailed and tissue-friendly bioelectronics.

In a study published in Advanced Science, the researchers describe how they can use light to create electrically conductive materials directly in the body, showing promising results in animal trials.

Bioelectronics is successfully used for treating heart arrhythmia, epilepsy, and neurodegenerative diseases like Parkinson’s, to name a few. However, it’s well known that today’s bioelectrodes and implantation methods require the tissue to adapt to the electrodes, rather than the other way around. This can lead to complications.

Letting AI models communicate with each other in their internal mathematical language, rather than translating back and forth to English, could accelerate their task-solving abilities.

The United States Food and Drug Administration has just approved the first-ever clinical trial that uses CRISPR-Cas13 RNA editing. Its aim is to treat an eye disease called wet age-related macular degeneration that causes vision loss in millions of older people worldwide.

This trial marks a new frontier in gene therapy —the process of treating or curing medical conditions by changing a person’s genes.

What makes it special is the fact the therapy targets RNA, instead of DNA. So, what does that mean, and why should we be excited?
