In a study published in the journal Science Advances, a team of European astronomers shows that water can be delivered to a terrestrial planet in the form of ‘pebble snow’ in the early phases of the planet’s growth.

  It used to be easy to know how many planets there were: nine. It had been nine planets for an entire generation before scientists started rethinking what counts as a planet. Pluto is out, but some astronomers believe there’s a real ninth planet lurking out there. Others aren’t convinced, …

Quercetin and 3,5-dihydroxybenzoic acid (DHBA), phytonutrients commonly found in apples, may help stimulate the production of new brain cells, according to a study published in the journal Stem Cell Reports. Quercetin and DHBA, natural compounds found in apples, are pro-neurogenic. Image credit: Ichwan et al., doi: 10.1016/j.stemcr.2021.01.005. Dr. Gerd Kempermann …

The primitive-looking coelacanth has long been regarded as a ‘living fossil,’ with extant specimens looking very similar to fossils dating back to the Cretaceous period. But while the coelacanth’s body may have changed little, its genome tells another story. Latimeria chalumnae off Pumula on the KwaZulu-Natal South Coast, South Africa, …

Flowering plants (angiosperms) are the most diverse of all land plants, becoming abundant in the Cretaceous period (145 to 66 million years ago) and achieving dominance in the Cenozoic (66 million years ago-present). However, the exact timing of their origin remains a controversial topic. To resolve this discrepancy, a team …

  The 20th century was notable for numerous reasons, not least of which that humanity split the atom. In the remnants of atomic explosions, scientists found never-before-seen elements like einsteinium. Now, almost 70 years after its discovery, scientists have collected enough einsteinium to conduct some basic analysis. Scientists understood that …

The parent body of the Almahata Sitta meteorites — space rocks that rained down on the Nubian Desert in Sudan in 2008 — is a 640 to 1,800 km-wide water-rich asteroid that is as yet unknown, according to new research. Hamilton et al. studied the composition of Almahata Sitta 202 …

Marine biologists from the University of Oregon and the University of New Brunswick have recorded common, previously unknown, ultrasonic vocalizations produced by Weddell seals (Leptonychotes weddellii), the world’s southernmost-ranging mammal. They’ve identified nine recurrent call types in more than one year (2017-2018) of broadband acoustic data obtained by a continuously …

In new research, researchers from the Max Planck Institute for Evolutionary Anthropology, Australian National University and the University of Guam analyzed ancient DNA from two humans who lived on Guam 2,200 years ago and found that their ancestry is linked to the Philippines. Moreover, they are closely related to ancient …
