Strains and media Strains used are listed in Supplementary Table 2 and plasmids in Supplementary Table 3. Strains and plasmids are available on request. Hanseniaspora strains were grown in standard rich medium (YPD; yeast extract, peptone, dextrose) or in synthetic complete dropout medium at 30 °C. DNA extraction and Nanopore sequencing DNA for nanopore sequencing was
Massive structures of slow, swirling, plume-like patterns were found hidden deep inside Greenland’s ice sheet years ago, but their source remained a mystery. Now, scientists believe they may have tracked down the mechanism responsible for Greenland’s plumes, and it’s wild. A team of international researchers suggests the enigmatic structures lurking beneath the surface may be
NASA’s Artemis II Fueling Test (Official Feed) – YouTube Watch On The second prelaunch test campaign for NASA’s Artemis 2 moon rocket is underway, and one of its most critical operations will happen today (Feb. 19). NASA’s Space Launch System (SLS) rocket entered hour 36 of its approximately 50-hour-long wet dress rehearsal (WDR) this morning,
Scientists say they have drilled deeper than ever beneath the West Antarctic Ice Sheet, peering back millions of years to reveal signs it was once, at least in part, open ocean. The vast expanse is estimated to hold enough ice to raise global sea levels by four to five metres (13 to 16 feet), said
Planet Earth is overrun with life. Lakes, rivers, seas, and oceans are teeming with it, from the surfaces all the way down to the bottom, often at depths of miles and miles. The land, both above and below ground, is packed with living organisms of varying size, mass, and complexity, including plants, animals, and fungi.

heic2605 — Science Release The elusive object dubbed CDG-2 may be composed of 99% dark matter 18 February 2026 Most galaxies in the nearby Universe are quite luminous, but some are so faint they’re nearly invisible. Astronomers, using the NASA/ESA Hubble Space Telescope in combination with other observatories, identified a galaxy that appears to be

It would take four centuries to reach its destination. It would carry 2,400 people who would never see the world they left or the world their descendants would eventually inhabit. It would need to generate its own gravity, grow its own food, recycle every molecule of water and air, and preserve enough technical and cultural
WASHINGTON — A new SpaceX initiative to provide space traffic coordination services has attracted attention and praise in part because of the conditions it places on users of it. SpaceX announced in late January Stargaze, a space situational awareness (SSA) system. Stargaze uses images from star tracker cameras on its nearly 10,000 Starlink satellites to
