Telling artificial intelligence models to “think” step by step when carrying out a task can improve their performance so much that they can outperform humans at jobs AIs usually struggle with.
Scientists have discovered several elusive species of microorganisms.
Researchers have found a number of very rare species of microorganisms, some of which have never been observed before and others which have eluded the attention of researchers for more than a century.
Professor Genoveva Esteban of Bournemouth University and James Weiss, an independent researcher working in his own lab in Warsaw, Poland, with his two cats, made the discovery of these elusive species and published their findings in the scientific journal Protist.
Providing highly efficient chemical processes that are also sustainable has become a key requirement for customers of the chemicals sector. While this is easier to achieve in large-scale, continuous processes for portfolio products, reaching similar levels of sustainability in multi-stage syntheses of complex, custom-manufactured molecules remains a challenge.
One solution to this problem is hydrogenation. When operated properly and with the appropriate knowledge and expertise, this technology is able to deliver excellent yields at high selectivity, and the catalysts applied in the process can often be re-used or recycled.
Researchers have developed a hackable and multi-functional 3D printer for soft materials that is affordable and open design. The technology has the potential to unlock further innovation in diverse fields, such as tissue engineering, soft robotics, food, and eco-friendly material processing—aiding the creation of unprecedented designs.

In a study using specialized imaging techniques, Johns Hopkins Medicine researchers report distinctive changes in the “white matter” and other brain tissue physiology of those with post-treatment Lyme disease, a condition affecting 10% to 20% of the nearly half a million Americans who contract Lyme disease annually.
The study’s findings, published October 26 in the journal PLOS ONE, substantiate and help validate that memory difficulties and other cognitive difficulties experienced long-term by individuals with post-treatment Lyme disease are linked to functional and structural changes in the brain.
Lyme disease, whose early symptoms may include a characteristic rash, flu-like aches and fever, joint pain, and fatigue, is treated using a rigorous course of antibiotics, which usually clears the illness.
SpaceX is making final preparations for the fourth launch of its Falcon Heavy vehicle, the world’s most powerful rocket in use today.
How does the human brain keep track of the order of events in a sequence?
Research suggests that ‘time cells’ – neurons in the hippocampus thought to represent temporal information – could be the glue that sticks our memories together in the right sequence so that we can properly recall the correct order in which things happened.
Evidence for these kinds of sequence-tracking time cells has previously been found in rats, where specific neuron assemblies are thought to support the recollection of events and the planning of action sequences – but for a long time, less was known about how episodic memory is encoded in the human brain.
A spectral image of methane entering the atmosphere caused by decomposition at a waste disposal site was produced by EMIT.
It is called EMIT and it can pinpoint methane emissions from human activities. Methane is a potent greenhouse gas.
Equipment from a 1937 expedition in the Yukon territory of Canada left by Bradford Washburn was found this year in an expedition started by skier Griffin Post.
