Venture funding into Europe is heading for a flat year, but this may obfuscate the fact that European AI startups are thriving.
The black hole information paradox has puzzled physicists for decades. New research shows how quantum connections in spacetime itself may resolve the paradox, and in the process leave behind a subtle signature in gravitational waves.
For a long time we thought black holes, as mysterious as they were, didn’t cause any trouble. Information can’t be created or destroyed, but when objects fall below the event horizons, the information they carry with them is forever locked from view. Crucially, it’s not destroyed, just hidden.
But then Stephen Hawking discovered that black holes aren’t entirely black. They emit a small amount of radiation and eventually evaporate, disappearing from the cosmic scene entirely. But that radiation doesn’t carry any information with it, which created the famous paradox: When the black hole dies, where does all its information go?
Astronomers have made a startling discovery. Using data from the eRosita X-ray instrument, researchers say they’ve discovered a “cosmic tunnel” that connects our solar system to other stars.
Scientists have long known that our solar system exists in a Local Hot Bubble. This bubble is believed to have formed following several supernovas over the past several million years and is estimated to be around 300 light-years across.
Using data from the eRosita, researchers from the Max Planck Institute say they found evidence of a cosmic tunnel stretching from our solar system out toward the Centaurus constellation. The tunnel appears to move through the material that makes up the Local Hot Bubble.
The University of Liverpool has created a hybrid nanoreactor that uses sunlight to produce hydrogen efficiently, offering a sustainable and cost-effective alternative to traditional photocatalysts.
The University of Liverpool has announced a major breakthrough in engineering biology and clean energy. Researchers have developed a groundbreaking light-powered hybrid nanoreactor that combines the natural efficiency of biological processes with the precision of synthetic design to produce hydrogen, a clean and renewable energy source.
Detailed in ACS Catalysis, the study introduces an innovative solution to a longstanding challenge in solar energy utilization for fuel production. While nature’s photosynthesis systems excel at harnessing sunlight, artificial systems have historically fallen short. This new approach to artificial photocatalysis represents a significant step forward in bridging that performance gap.
Sadly, we know that microplastics are getting everywhere, including our drinking water – but researchers have developed a new way to tackle the problem: a filter made of a rather unusual combination of material, which is able to remove up to 99.9 percent of tiny plastic fragments from water.
The researchers, led by a team from Wuhan University in China, combined both chitin (derived from squid bone) and cellulose (derived from cotton) for their ‘Ct-Cel’ foam filter. Both materials are found in abundance in nature, cheap to adapt, and sustainable.
They then tested their filter against numerous different types of plastic, finding it did an excellent job with a wide variety of fragment sizes and plastic types – including some of those most commonly seen in microplastic pollution.
Aurora chasers are on high alert for minor geomagnetic storm conditions on Dec. 25. Northern lights could be visible over some northern and upper Midwest states.
Wherever astronomers look, they see life’s raw materials—and hints at answers to one of the great mysteries of science.
But when, where and how that could come to pass is hard to predict — in part, some researchers say, because of guardrails the federal government has placed around gain-of-function research.
The term describes experiments that seek to understand a virus’ potential to adapt to new hosts, spread more easily, survive longer in the environment and cause those infected to become sicker. Though many scientists view the approach as a critical tool for conducting biological research, other experts have long complained that it’s unacceptably risky — a reputation exacerbated by persistent speculation that the virus responsible for the COVID-19 pandemic was created in gain-of-function experiments in a laboratory in Wuhan, China.
The Parker Solar Probe will swoop just 6.1 million kilometers above the sun’s surface on Christmas Eve. Scientists are thrilled at what we might learn.

There are some places in the solar system no human will ever go. The surface of Venus, with its thick atmosphere and crushing pressure, is all but inaccessible. The outer worlds, such as Pluto, are too remote to presently consider for anything but robotic exploration. And the sun, our bright burning ball of hydrogen and helium, is far too hot and tumultuous for astronauts to closely approach. In our place, one intrepid robotic explorer, the Parker Solar Probe, has been performing a series of dramatic swoops toward our star, reaching closer than any spacecraft before to unlock its secrets. Now it is about to perform its final, closest passes, skimming inside the solar atmosphere like never before.
