It takes two to tango, and yet when it comes to research on human reproduction, female fertility has historically taken the lead.
Now, emerging research is putting a new foot forward.
Sperm from older fathers may show more signs of aging than we thought, and not just from DNA mutations.
Large language models (LLMs), the artificial intelligence (AI) systems underpinning the functioning of ChatGPT and other conversational agents, are now widely used to source information, summarize texts and generate content for specific purposes. These models essentially generate their responses by predicting sequences of words based on the patterns they learned during previous training.
An LLM’s ability to generate useful responses, however, does not necessarily ensure consistency between its answers and its evaluations of others’ reasoning. One way to investigate this consistency is through tasks involving Bayesian reasoning, a reasoning strategy that entails combining existing information with new evidence to estimate probabilities. Bayes’ rule provides a mathematical formula for updating these probabilities.
Some psychology studies have shown that humans sometimes use Bayesian reasoning when making decisions, yet they criticize others who make judgments using this approach. This tendency is known as Bayesian hypocrisy. For instance, people might estimate that a pilot is statistically more likely to be male, while viewing someone else who makes a similar judgment as sexist.
Leonard Rome and Nancy Kedersha first identified vault particles in 1986. These hollow, barrel-shaped structures rank among the largest protein complexes found in human cells. Mammalian vaults contain 78 copies of a major protein arranged into two symmetrical halves.
Their biological purpose remains uncertain despite decades of investigation. Researchers have proposed roles in cellular transport, drug resistance, and immune defense. However, experiments have yet to establish any of these functions conclusively.
At autopsy, hearts of patients with RA or lupus were more often scarred and enlarged than those of car crash victims serving as controls, and these findings were tied to deaths from heart disease.
Ancient moss frozen beneath Baffin Island’s ice tells the story of a glaciation humans snuffed out.
Advances in machine learning and computational imaging are transforming not only how scientists analyze data but how they conduct entire experiments. At U.S. Department of Energy (DOE) user facilities, researchers are integrating machine learning directly into experimental workflows—using it to identify what to measure, reconstruct images as data are collected and rapidly extract scientific information.
SYNAPS-I (Synergistic Neutron and Photon Science—Intelligence), a seed project under the ModCon initiative within DOE’s Genesis Mission, is bringing these capabilities together across X-ray light source and neutron facilities. Led by DOE’s Lawrence Berkeley National Laboratory’s Advanced Light Source, the multilaboratory collaboration includes DOE’s Argonne National Laboratory, DOE’s Oak Ridge National Laboratory, DOE’s SLAC National Accelerator Laboratory and DOE’s Brookhaven National Laboratory.
The project combines expertise across the laboratories with open-source computational intelligence models, industry partnerships and advanced computing resources to develop shared solutions for faster, more efficient imaging.
MIT researchers developed BIOSENTER, a snake-inspired soft robot designed to evaluate, biopsy, and deliver drugs to the small intestine.

Agility Robotics is about to give Wall Street a reality check on the humanoid robot boom.
The Oregon startup, whose two-legged robots carry heavy materials and sort goods in factories and warehouses, is expected to begin trading on Nasdaq on Thursday, becoming the first humanoid-focused company to go public in the US. Its financial disclosures show just how far the industry still has to go before robots become a profitable business.
Agility brought in just $1.8 million in revenue last year while reporting a $138.1 million net loss, according to its merger filings. More than half its revenue came from five robots purchased by one of its investors.
CSA (Canadian Space Agency) astronaut Joshua Kutryk is pictured during the Oct. 29, 2026, spacewalk. The International Space Station was soaring 267 miles above the South Atlantic Ocean at the time of this photograph. Kutryk and NASA astronaut Anil Menon installed a new roll-out solar array on the space station and performed some get-ahead work for their next spacewalk, which will take place on Nov. 5, 2026. The pair will install the eighth and final roll-out solar array; together, the eight arrays will increase the station’s available power by up to 30%.
