It is thought that Euclid wrote Elements in about 300 BC, but Oliver Byrne turned it into one of the true gems of visualization — and made it about 100 times more readable. By seamlessly combining typeset text (Caslon, if you’re interested) with minimalist geometric drawings in primary col
New evidence suggests anyone infected with COVID is at higher risk for heart issues—a risk that persists even in relatively healthy people long after the illness has passed.
A new study suggests that electric fields may represent information held in working memory, allowing the brain to overcome “representational drift,” or the inconsistent participation of individual neurons
Explore Capella blogs, case studies, and insights on SAR, space systems, and Earth intelligence.
ETH Zurich researchers have developed a process that can be used on site to render environmental toxins such as DDT and lindane harmless and convert them into valuable chemicals – a breakthrough for the remediation of contaminated sites and a sustainable circular economy.
MIT team gets water to freeze solid at boiling temperature; finding could lead to new kinds of electronic devices with wires made of ice

MIT researchers have produced the first “laser ultrasound” images in humans, using eye- and skin-safe lasers. The new technique enables noncontact ultrasound imaging, which may help clinicians to remotely assess patients, infants, and contact-sensitive subjects such as burn victims.
All modern language models sometimes act like they have emotions. What’s behind these behaviors? Our interpretability team investigates.
In their quest to understand how the immune system is implicated in alcohol use disorder, Scripps Research scientists have found a potential path for treatment.
Nuclear power already has an energy density advantage over other sources of thermal electricity generation. But what if nuclear generation didn’t require a steam turbine? What if the radiation from a reactor was less a problem to be managed and more a source of energy? And what if an energy conversion technology could…
A new study has found that some commonly consumed beverages contained levels of toxic metals that exceed federal drinking water standards.
Microsoft and Warner Brothers collaborate to store and retrieve the 1978 'Superman' movie on a piece of glass roughly the size of a drink coaster.
Faster, more secure connections from space could one day make broadband on planes, ships and even remote roads as easy as turning on a light. The European Space Agency (ESA), Airbus Defence and Space, the Netherlands Organisation for Applied Scientific Research (TNO) and German payload manufacturer TESAT (as…
The Stanford Medicine sleep researcher is honored for discovering the role of orexins in narcolepsy and paving the way to new sleep disorder therapies.
Scientists at the Institute of Optics have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings.
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells “walk” toward each other to close a wound for the first time. An associate professor in Molecular Genetics and Cell Biology at the University of Chicago, Malamy had received transparent, dime-sized medusae of the…
Infrared laser pulses modify the structure of the high-temperature superconductor YBCO and make superconductivity possible at room temperature.
A new European Southern Observatory (ESO) study has found that current proposals to launch over 1.7 million satellites into orbit, including extremely bright ones, would have “devastating consequences for astronomy.” According to the study, no more than 100 000 faint satellites, below naked eye visibility, should…
Understanding and identifying when and why people use social media can inform intervention strategies that teach people when to seek connections, social support, or strengthen their offline relationships.
Research shows the biological aging process can be slowed by strong social connections and support.
The blood-based biomarker test is based on technology developed at WashU Medicine by Randall Bateman, MD, and David Holtzman, MD.
