Princeton University researchers reported in a new study that unless greenhouse gas emissions are curbed, marine biodiversity may be on track to plummet to levels not seen since the extinction of the dinosaurs. The scientists modeled future marine biodiversity under projected climate scenarios and found that species such as dolphinfish (shown) would be imperiled as … Read more

Credit: Illustration by Siena Fried for Tufts University Surprising research findings in mice could lead to new insights and treatments for a wide range of brain and neurological diseases, from epilepsy to Alzheimer’s. Researchers at Tufts University School of Medicine have discovered … Read more
Artist conception of the James Webb Space Telescope. Credit: NASA GSFC/CIL/Adriana Manrique Gutierrez The Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope is now cooled by a gaseous helium cryocooler to under 7 kelvins (minus 447 degrees Fahrenheit, or minus 266 degrees Celsius). With the cooler in its final state, the Webb team is … Read more
Ultrafast magnetic scattering on ferrimagnets enabled by a bright Yb-based soft x-ray source, which made the cover of Optica. Credit: Ella Maru Studio INRS researchers and international partners have succeeded in looking at spin inside rare earth materials, using a tabletop ultrafast soft-X-ray microscope, for the first time. Complex networks of systems are required for … Read more
This artist’s concept depicts astronauts and human habitats on Mars. Credit: NASA Photovoltaics may be more practical for long stays on Mars thanks to today’s light, flexible solar panels. According to new research by scientists at the University of California, Berkeley, the high efficiency, lightweight, and flexibility of the current solar cell technology means photovoltaics … Read more
Researchers published a new study that provides insight into the genetic basis of heritable traits using an unusual experimental paradigm that included 240,000 strains of brewer’s yeast descended from two common “parents.” An analysis of 240,000 yeast strains reveals the complex interplay between large-impact genetic markers and genetic background. Enormous dataset presents unprecedented detail of … Read more
Scientists have taken a significant step in understanding these whirling quasiparticles and putting them to work in future semiconductor technologies. Researchers reported that they have imaged the exciton’s electron and hole for the first time, revealing how excitons may be trapped in dense, stable arrays. According to the scientists, the findings have significant implications for … Read more
Artist’s impression of exocomets orbiting the star ß Pictoris. Credit: © ESO/L. Calçada For the past thirty years, astronomers have been fascinated with the star ß Pictoris because it allows them to observe a young planetary system in the process of formation. It is made up of at least two young planets, as well as … Read more
