Hidden companion likely stole material from star A close celestial companion of some kind likely siphoned off the mass of a star before it exploded into an unusual supernova, ejecting very little material. “We call this an ultrastripped envelope supernova,” said Mansi Kasliwal of the California Institute of Technology, adding that the observation is “the […]
Flu outbreaks likely influenced by city size, crowding A city itself influences the contours of its flu season – whether flu cases rise to a wintertime peak or plateau from fall to spring. ScienceNews Review shows vitamin D does not prevent falls, fractures A review of data from 81 studies found vitamin D supplements do […]
Huge Jurassic-period dinosaur had crouching posture An enormous Jurassic-period dinosaur that walked on all fours with an unusual crouching posture has been described in a new study after its remains were fully unearthed last year.

Plastisphere studies reveal myriad microbes that may one day clean it up Oceanographer Maria-Luiza Pedrotti and her research team are studying the plastisphere — plastic waste and its byproducts — in the Pacific Ocean and Mediterranean Sea to identify the microbes that populate plastic and determine their biological activities to understand how they affect the […]
New map offers detailed view of Antarctica A new high-resolution map is giving researchers a much more detailed view of Antarctica. Images from the Reference Elevation Model of Antarctica, or REMA, will be made available for free to scientists studying the continent.

A new shape inside your skin The type of cells responsible for forming skin and the lining of an organism’s organs will morph into “scutoids” in order to accommodate those organs’ complex curvature. Motherboard A leap toward lifelike model of human heart Scientists have bioengineered a 3D model of the human heart’s left ventricle, which […]
Gulf Stream’s slowdown may increase global temperatures The slowing of the Gulf Stream could lead to higher temperatures around the world. Researchers examined the Atlantic Meridional Overturning Circulation over the past seven decades and noted patterns that suggest Earth could be experiencing a similar warming period as it did from 1975 to 1998.
