This striking image from the science camera on ESA’s Jupiter Icy Moons Explorer (Juice) shows interstellar comet 3I/ATLAS spewing dust and gas. The tiny nucleus of the comet (not visible) is surrounded by a bright halo of gas known as the coma. A long tail stretches away from the comet, and we see hints of
Mice were given acetate and then performed tasks that tested their memory.Credit: fergregory/iStock via Getty A common metabolic by-product produced when the body breaks down alcohol, glucose and food high in fibre can enhance memory, at least in females, according to a study in mice1. In the study, published in Science Signaling, scientists injected acetate
A total lunar eclipse will create a stunning “Blood Moon” on March 3 (Credit: Jacek Rużyczka/ CC BY-SA 4.0/ Wikimedia Commons) Skywatchers are in for a treat. On March 3, 2026, a spectacular total lunar eclipse will turn the Moon a deep reddish color, creating what is known as a “Blood Moon.” The eclipse will
Seeing a color in nature is one thing. Recreating colors artificially is an entirely different challenge—one with some unexpectedly high stakes. Practically anything human-made is of a certain color thanks to artificial pigments, or chemical compounds that appear a specific color. An ongoing challenge is that, as chemical bonds naturally fade, so does the color.
We all know we live in three-dimensional space. But what does it mean when people talk about four dimensions? Is it just a bigger kind of space? Is it “space-time”, the popular idea which emerged from Einstein’s theory of relativity? If you have wondered what four dimensions really look like, you may have come across
Scientists report the first confirmed field observation of a rare class of electrical phenomena associated with vegetation that has eluded scientific confirmation for nearly a century. For many decades, observers have logged reports of unusual glows emitted by vegetation, with a leading theory of their cause being faint electrical discharges triggered by atmospheric activity associated
Recent advancements in climate research have shed light on a crucial element of global sea-level rise: the mass of water added to the oceans, primarily from melting land ice. A new study, published in the Proceedings of the National Academy of Sciences, highlights how space-based technologies, including satellite laser ranging (SLR), are now being used
For millions of years, Earth’s history has been shaped by cosmic impacts, yet one ancient collision in Brazil remained hidden, until now. A recent study published in Geology has uncovered evidence of a meteorite strike that occurred 6.3 million years ago. Led by Álvaro Penteado Crósta, the discovery reveals a new field of tektites, expanding
replying to: C. Candelora & I. Zeljkovic Nature https://doi.org/10.1038/s41586-026-10126-1 (2026). In our paper1, we demonstrate that the relative intensities of charge-density-wave (CDW) peaks in the Fourier transform of STM topographies of RbV3Sb5 can be controlled by an electric field induced by laser light. Moreover, we show that this change in the intensities is accompanied by
The United States Space Force has been testing its top-secret Boeing X-37B space plane for over a decade. Two versions of the unusual spacecraft have completed seven orbital missions over the last 15 years, spending a combined thousands of days in space. Despite its extensive experience of being launched atop a rocket and slowing its
