A procedure that could be done in half an hour, and prepared ahead of time, could seriously reduce blood loss from severe wounds, such as during surgery

An experiment with a carbon material in a magnetic field has revealed a novel way for electrons to move, which doesn't fully belong in two or three spatial dimensions

A wave of dinosaur discoveries over the past decade has completely reshaped our understanding of these long-extinct animals. Palaeontologist Dave Hone spills the secrets of how dinosaurs lived, from how social they were to how much they really fought 

On top of Kitt Peak in the Arizona Desert, a robotic surveyor just completed a five year mission to catalogue the positions of tens of millions of galaxies. The Dark Energy Spectroscopic Instrument (DESI) has now created the largest, most detailed 3D map of our universe ever constructed. And it’s not done yet, its main mission has been extended through 2028.

Reports suggest that Apple is using defective chips originally destined for high-end devices to create its latest affordable laptop. Reusing partially broken chips is common practice for all device makers and produces less waste

At SBM we have two basic missions, which are really just different ends of the same spectrum. We are trying to raise the ceiling of rigorous science in the practice of medicine. This is a complex topic involving factors such as statistical methods, preregistering trials, p-hacking, and various forms of publication bias. At the same time we are trying to raise the […]

Many scorpion species use blends of iron, zinc and manganese to enhance the toughness of their deadly weaponry

Europe, the fastest-warming continent, saw unprecedented wildfires and heatwaves in 2025, including a three-week hot spell that hit 30°C inside the Arctic circle

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion light-years away, appears five times in the sky thanks to gravitational lensing, creating a dazzling “cosmic fireworks” effect. By measuring the slight delays between each appearance—caused by light taking different paths around two foreground galaxies—scientists can directly calculate the universe’s expansion rate.

Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets being designated as terrestrial (rocky) exoplanets. With the promise of discovering an increasing number of Earth-sized exoplanets increasing every day, new telescopes from across the world have the opportunity to contribute to this incredible field.

Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a telltale U-shaped pattern showing that star formation drops sharply around 35,000–40,000 light-years from the center. Beyond that, stars are mostly migrants, slowly drifting outward rather than forming in place. The discovery gives a long-sought answer to where our galaxy’s stellar nursery really ends.

You’re in the lab analyzing Martian regolith samples within your cozy Mars habitat serving on fifth human mission to Mars. The power within the habitat has been flowing flawlessly thanks to the MARS-MES (Mars Atmospheric Resource & Multimodal Energy System), including the general habitat lighting, science lab, sleeping quarters, exercise equipment, the virtual reality headsets the crew use for rest & relaxation, oxygen and fuel generation, and water. All this from converting the Martian atmosphere into workable electricity.

Scientists at the Max Planck Institute for Solar System Research have produced the most detailed simulations ever of solar prominences. These vast clouds of cooler plasma suspended in the Sun's scorching outer atmosphere have often perplexed solar astronomers. Their research reveals that two separate processes work together to keep these structures alive, and could one day help us predict the violent eruptions that drive dangerous space weather here on Earth.

Obesity might be to blame for part of the increase in cancer among young people, a study in the UK has found, but the causes largely remain a mystery

Our Galaxy's halo of hot gas is measurably warmer on one side than the other and a team of scientists have found the culprit. The gravitational pull of the Large Magellanic Cloud is drawing the Milky Way slowly southward, compressing the gas in its path and heating it up, much like a piston in an engine. The discovery solves a puzzle that has intrigued astronomers since the temperature difference was first detected in 2024.

Where exactly is the edge of the Milky Way? That question is harder to answer than one might expect. Since we’re inside of the galaxy itself, it’s obviously hard to judge the “edge” to begin with. But it gets even more complicated when defining what the edge even is - the galaxy simply gets less dense the farther away from the center it goes. A new paper by researchers originally at the University of Malta thinks they have an answer though. The “edge” can be defined as the star-forming region, and in their paper, published in Astronomy & Astrophysics, they very clearly show that “edge” to be between 11.28 and 12.15 kiloparsecs (or about 40,000 light years) from the center.

People are increasingly placing bets that predict measles outbreaks in the US, which could help researchers modelling the spread of the disease

Millions of dollars are being spent on wagers predicting measles outbreaks in the US, which could help researchers modelling the spread of the disease

The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of science is under construction that centres conscious experience – and might unravel the universe’s biggest mysteries

The 570 megapixel Dark Energy Camera captured this image of the iconic Sombrero Galaxy. The galaxy has characteristics of both elliptical galaxies and spiral galaxies, and is likely the result of multiple mergers and cannibalizations of dwarf galaxies. A faint stellar stream, only fully traced a few years ago, is revealed by DECam's resolving power.
