We can"t see the first stars yet, but we can see their direct descendants
If you take a universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us. We are the descendants of the primeval elements. We are the cast-off dust of the first stars, and many generations of stars after that. So ou.....»»
Winter isn"t coming: climate change hits Greek olive crop

New constraints on the presence of ultralight dark matter in the Milky Way
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional experimental meth.....»»
Astronomers discover two "hot Jupiters" orbiting red-giant stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit distant red-giant stars. The.....»»
Dwarf galaxies use 10-million-year quiet period to churn out stars
If you look at massive galaxies teeming with stars, you might be forgiven for thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of.....»»

ALMA observation of young star reveals details of dust grains
One of the primary goals of the Atacama Large Millimeter/submillimeter Array (ALMA) is to study the formation and evolution of planetary systems. Young stars are often surrounded by a disk of gas and dust, out of which planets can form......»»
Vinigrol targets protein disulfide isomerase to block inflammatory response, shows study
Researchers led by Prof. Wang Lei from the Institute of Biophysics of the Chinese Academy of Science (CAS) and their collaborators have identified the direct target of vinigrol as protein disulfide isomerase (PDI) on the cell membrane. Vinigrol activ.....»»
Deep-sea coral evidence found for enhanced subglacial discharge from Antarctica during meltwater pulse 1A
Subglacial discharge from the Antarctic Ice Sheet (AIS) likely played a crucial role in the loss of ice sheet and the subsequent rise in sea level during the last deglaciation. However, no direct proxy is currently available to document subglacial di.....»»

Astronomers find dozens of massive stars fleeing the Milky Way
The Milky Way can't hold onto all of its stars. Some of them get ejected into intergalactic space and spend their lives on an uncertain journey. A team of astronomers took a closer look at the most massive of these runaway stars to see what they coul.....»»
