Researchers have demonstrated a new and sustainable way to make the chemicals that are the basis of thousands of products—from plastics to cosmetics—we use every day.

Hundreds of thousands of chemicals are manufactured by the chemical industry, which transforms raw materials—usually fossil fuels—into useful end products. Due to its size and its use of fossil fuel feedstocks, the chemical industry is responsible for roughly 6% of global carbon emissions.

But researchers led by the University of Cambridge are developing new methods that could one day lead to the “de-fossilization” of this important sector.

They have developed a hybrid device that combines light-harvesting organic polymers with bacter...

One of the most notable properties of the giant planets in our solar system—Jupiter, Saturn, Uranus and Neptune—are the extreme winds observed around their equators. While some of these planets have eastward equatorial winds, others have a westward jet stream...

Large language models (LLMs), which power sophisticated AI chatbots, are more vulnerable than previously thought. According to research by Anthropic, the UK AI Security Institute and the Alan Turing Institute, it only takes 250 malicious documents to compromise even the largest models.

The vast majority of data used to train LLMs is scraped from the public internet. While this helps them to build knowledge and generate natural responses, it also puts them at risk from data poisoning attacks...

According to a new Physical Review Letters study, black holes could help solve the dark matter mystery. The shadowy regions in black hole images captured by the Event Horizon Telescope can act as ultra-sensitive detectors for the invisible material that makes up most of the universe’s matter.

Dark matter makes up roughly 85% of the universe’s matter, but scientists still don’t know what it actually is. While researchers have proposed countless ways to detect it, this study introduces black hole imaging as a fresh detection method—one that comes with some distinct benefits.

The...
