Engineers created an ingestible pill-shaped device that could let scientists monitor glucose in the intestines in real-time. The new sensor could be used to gain better data on gastrointestinal disorders with less discomfort to patients than current monitoring methods.
A composite image showed the Pillars of Creation in a spectacular new light. The star-forming region of the Eagle Nebula has been a compelling telescope target since Hubble captured its image in 1995. The new image combines JWST’s Near-Infrared Camera and Mid-Infrared Instrument to show a swath of wavelengths beyond human sight.
Researchers determined modern lizards first appeared in the late Triassic, 35 million years earlier than previously thought. The researchers identified Cryptovaranoides microlanius, a lizard in the squamate order alongside modern snakes and lizards, from an unnamed fossil in London’s Natural History Museum.
Astronomers determined a long-duration gamma ray burst detected in 2021 was caused by a kilonova — an explosion smaller than a supernova made by merging stars. Unlike typical GRBs from kilonovae which last mere seconds, this lasted more than a minute, upending assumptions about how GRBs form.
Researchers discovered 2-million-year-old fragments of DNA in northern Greenland. The DNA, found in sediment dating to the Ice Age, predates the next-oldest known DNA by 1 million years. The fragments show ancestors of modern-day species along with mastodons, not previously thought to inhabit Greenland.
