NASA delays Artemis II moon mission to March after critical test raises issues

NASA has delayed its upcoming moon mission to at least March following a crucial test of the Artemis II rocket. Technically a test flight, Artemis II will see four astronauts fly a 10-day journey around the moon and back to Earth, a mission that will take them farther into space than any human has gone before. Artemis I, the predecessor mission to Artemis II, also suffered from fuel leaks during its wet dress rehearsal and at other points in the lead-up to the mission, causing its launch to be delayed by weeks.

A century of hair clippings show lead exposure rates have plummeted

NEWS | 04 February 2026
The analysis didn’t distinguish between lead in the sheathlike cuticle that surrounds a hair and that found in the hair itself. Peak lead rates occurred in samples from the 1960s, when lead was enriched by some 120 times compared with 2020–2024 samples. But since the 1960s, lead exposure rates steadily plummeted. By tapping biological information stored in people’s keepsake locks of hair, Smith and his team were able to push that time line back. “As a toxin goes, lead is serious, and we should certainly be concerned and striving to lower population exposure,” Kordas says.

The sun just unleashed its most powerful solar flare in years

NEWS | 04 February 2026
An X-class solar flare captured on camera by NASA’s Solar Dynamics Observatory in 2013. The sun is experiencing a violent solar storm, releasing one of the strongest solar flares seen in the past 30 yearsI agree my information will be processed in accordance with the Scientific American and Springer Nature Limited Privacy Policy . On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. When these fields snap, they can throw out huge bursts of energy and charged particles into space—a solar flare. The sun’s activity fluctuates on an 11-year time line, and while the star is believed to be beyond the peak of its current solar cycle, strong solar flares may continue for some time as it winds down.

Your guide to 29 wildly different theories of consciousness

By providing your email address, you also consent to having the email address shared with third parties for those purposes. Some of these theories have many publications to their name, such as global workspace theories, higher-order theories and integrated information theory, three of the field’s leading models. This may explain why quantum theories of consciousness, which are fascinating but not yet grounded in much evidence, have been proposed so many times. Predictive processing theories, which are also influential in the field, are notably absent, perhaps because they originated as theories of perception rather than consciousness. 11; April 2021 (data)THEORY CHARACTERISTICSAll of these proposals are wildly different, and only some are supported by evidence.

JWST could finally spot the very first stars in the universe

NEWS | 04 February 2026
Known as dinosaur stars for both their primeval nature and their immense size, Population III stars existed only when the universe was very young. By far the most abundant form of matter in the universe, dark matter has evaded detection by the most advanced laboratories on Earth. If these structures are dominated by dark matter, they will rule out certain theories of dark matter under which it couldn’t form such small structures. Future observations of these and other lensed stars can tell us more about what dark matter can and can’t be. These studies also suggest that dark matter may have bizarre quantum properties that scientists call “fuzzy,” giving dark matter weird wavelike characteristics.

Life’s evil twins—mirror cells—could doom Earth if scientists don’t stop them

NEWS | 04 February 2026
Already biochemists can create increasingly complex mirror molecules, including enzymes that build mirror RNA. Groups of chiral molecules are usually referred to as “left-handed” or “right-handed,” depending on which orientation they have in common. Your immune system also has an adaptive system of specialized immune cells and antibodies that attack and destroy invading microbes. As the danger of mirror cells became more apparent, a team of scientists began working on what to do. Cyanobacteria are simple organisms that derive nutrition directly from sunlight and carbon dioxide, and they often don’t require any chiral nutrients.

How extremophile molds are destroying museum artifacts

NEWS | 04 February 2026
Most frustrating for curators, these xerophilic molds are undetectable by conventional means. Hats from Denmark’s Roskilde Museum that have been stored in a climate-controlled warehouse outside Copenhagen exhibit shimmery, whitish patches from xerophilic molds. Genetic analysis revealed they were four related species of xerophilic molds in a group known as Aspergillus section restricti. To that end, Sterflinger and her team in Vienna are busy trying to determine just how little water xerophilic molds can survive on. Letting go of the shame is the only way we can learn about these molds, Pinzari says.

Can a buried time capsule beat Earth’s geology and deep time?

NEWS | 04 February 2026
The same is true for anyone aspiring today to send such an envoy into the geological deep future. If we aspire to send a time capsule deep into the future, then Holland’s work is sobering. Some of this rock is from pieces of deep ocean crust that occasionally got smudged onto the sides of the continents during collisions and outlived the rest of their plates. If it’s stupid to put our time capsule on the deep ocean floor, which gets continuously destroyed, what about these narrower perches just offshore? If so, it would only mirror its more mature counterparts across the Atlantic today: two crescents of deep ocean trench where the seafloor is similarly being fed to the mantle.

Mathematicians Discover a New Kind of Shape That’s All over Nature

NEWS | 04 February 2026
Violet FrancesWhen the trio eventually identified a space-filling 3D shape with just two corners, Domokos thought they’d found their answer. By mapping an infinite category of polyhedral tilings to soft tilings, he proved the existence of an infinite class of soft cells. But the researchers struggled to identify these 3D soft cells in the real world. Zebra stripes, river estuaries, cross sections of onions, seashells, heads of wheat, red blood cells, plants and fungi all resembled 2D soft cells. Asked where he thinks soft cells belong in the scientific landscape, he doesn’t skip a beat.

These Mysterious Shapes Are at the Heart of Math’s Biggest Puzzles

NEWS | 04 February 2026
When most people think of shapes, they imagine a triangle, a rectangle, or maybe even a fancier-sounding rhombus or trapezoid. We asked mathematicians to choose their favorite shapes and surfaces and tell us why they find them so exciting and intriguing. We can construct every hyperbolic surface by sewing together hyperbolic pairs of pants and describe all of them entirely in terms of the boundary lengths and twist angles in this decomposition. A topological image of a curve (shape) is a set of points in the plane that satisfies an equation and has a complicated topological structure. The slice-ribbon conjecture, a major open problem in low-dimensional topology, says every such simple knot in 4D comes from a ribbon disk.

How Squishy Math Is Revealing Doughnuts in the Brain

A computer’s inability to see these relationships is a problem for scientists who want to identify circular patterns within huge masses of data points. To expand this structure into a simplicial complex, the mathematicians colored in this hollow triangle with a solid, two-dimensional triangle. They converted each of these maps into a simplicial complex and analyzed how its shape changed in time using the tools of topology. Because this mesh contains fewer data points, its simplicial complex contains shapes of lower dimensions. In effect, as the researchers recorded the state of the system at different instants, they accumulated high-dimensional data points.

Citizens' Assemblies Are Upgrading Democracy: Fair Algorithms Are Part of the Program

NEWS | 04 February 2026
The Irish citizens’ assembly is just one example of a widespread phenomenon. Citizens’ assemblies in France, Germany, the U.K., Washington State, and elsewhere have charted pathways for reducing carbon emissions. The effectiveness of citizens’ assemblies isn’t surprising. Descriptive representation, in turn, lends legitimacy to the assembly: citizens seem to find decisions more acceptable when they are made by people like themselves. Our algorithm was released as open source in 2020 and has since become a common method for selecting citizens’ assemblies.
