More than 300 million kilometres from the nearest mechanic, NASA's Curiosity rover found itself in a situation that would make any engineer break into a cold sweat. A rock got stuck to its drill and wouldn't let go. What followed was a week long, long distance rescue operation that says as much about the ingenuity of the people behind the machine as it does about the extraordinary challenges of exploring another world.

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system. Even more exciting, these strange particles may be adjustable, allowing scientists to tune their behavior in ways never before possible.

If a key ocean current collapses it could plunge northern Europe into a big freeze. Now researchers are weighing up a drastic intervention – building a 130-kilometre-wide dam between the US and Russia

Astronomers are puzzling over another oddball on the edge of the solar system: This time, it's an icy object less than a quarter of Pluto's size with a thin atmosphere – a layer of gas that's not typically found around objects so small.

The Department of Defense has released a fresh batch of images and transcripts relating to reports of unidentified anomalous phenomena, formerly known as UFOs, including pictures and descriptions from NASA's Apollo missions to the moon.

The US Department of Defense has released hundreds of documents and photographs related to UFOs, some of which have been declassified, in the first of many drops to come

Black holes evaporate through Hawking radiation, meaning their days are numbered. But a new study finds they could enter a metastable stage where they look similar to white holes.

Many flowering plants have duplicated genomes, which could have helped them evolve to deal with extreme stress in times of environmental upheaval

A drone has crashed in the Chernobyl exclusion zone, causing a fire that has spread to 12 square kilometres of land. Dry weather, strong winds and the presence of land mines are complicating efforts to bring the blaze under control

Aerospace engineers have to consider numerous factors when designing a spacecraft, but one that comes up more and more often is the need to design against Micro-Meteoroids and Orbital Debris (MMOD). While most designers understand the threat, designing structural solutions capable of withstanding the hypervelocity impacts these undercontrolled pieces of material can cause can take a significant bite out of a mission’s mass budget. A new paper from Binkal Kumar Sharma of the University of Bremen and Harshitha Baskar, an independent researcher, provides a detailed review of cutting-edge options for defending against those deadly particles.

Satellite measurements show that in the early 2010s sea level rise suddenly accelerated to a rate of 4.1 millimetres per year, possibly in response to an increase in the rate of global warming

How important is thinking about your breath for calming yourself down? We now know that slow breathing is effective even without conscious involvement

An impression made in clay around 175,000 years ago could be a kneeprint left by one of the builders of a strange stalagmite circle found deep inside Bruniquel cave in south-west France

A secret society of French mathematicians has been revolutionising the field of mathematics under a pseudonym for nearly a century. Columnist Jacob Aron finds that this mythic collective provided maths a rigorous and useful foundation, and did some real harm along the way

Scientists may have uncovered a surprising secret behind why life exists at all. A new study suggests that the Universe’s fundamental constants — the deep physical rules that govern everything from atoms to stars — appear to sit within an incredibly narrow “sweet spot” that allows liquids to flow properly inside living cells. Even tiny shifts in these constants could make blood too thick, water too sticky, or cellular motion impossible, potentially wiping out life as we know it.

Anyone who truly values open and rational discussions about controversial subjects need to be cleared-eyed about where the threat to such dialogue is coming from.

A mysterious comet from beyond our solar system is giving astronomers a rare glimpse into alien worlds — and it may have formed in a place far colder and stranger than anything around our Sun. The interstellar visitor, called 3I/ATLAS, contains an astonishingly high amount of “heavy water,” far exceeding anything seen in our own solar system.

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated smashups inside incredibly crowded star clusters. These violent chain reactions appear to create a distinct class of rapidly spinning black holes that stand apart from ordinary ones formed by dying stars.

When researchers look up at the sky and wonder if we’re not alone, they also realize the origins of life here on Earth might hold the key to finding out. The chaotic chemical soup of our early world eventually led to the staggering complexity of modern life, but how exactly did it start? Proteins were one of the key ingredients in the early years, but we’re still only just discovering how these marvels of modern biology first managed to fold, function, and survive. A new review paper, The borderlands of foldability: lessons from simplified proteins, published recently in Trends in Chemistry, showcases how scientists are attempting to answer this question - by researching “simplified proteins”.
