Scientists find oldest fossil of a land animal
A fossilized millipede-like creature discovered in Scotland may represent the oldest-known land animal, a humble pioneer of terrestrial living 425 million years ago that helped pave the way for the throngs that would eventually inhabit Earth's dry parts.
Solved: The mystery of the expansion of the universeThe Earth, solar system, the entire Milky Way and the few thousand galaxies closest to us move in a vast "bubble" that is 250 million light years in diameter, where the average density of matter is half as high as for the rest of the universe.
Solar storms may be linked to mass grey whale strandings
Each year, grey whales travel more than 16,000 kilometres along the Pacific Coast, from Mexico to Alaska and back. But every so often, many of them become stranded. Now a new study suggests these strandings could be linked to solar storms.
Fast radio burst with steady 16-day cycle observedA large team of space scientists working in Canada has found evidence of a fast radio burst with a steady 16-day cycle. The team has published a paper describing their findings on the arXiv preprint server.
Deep Diving Scientists Discover Bubbling CO2 Hotspot
AUSTIN, Texas — Diving 200 feet under the ocean surface to conduct scientific research can lead to some interesting places. For University of Texas at Austin Professor Bayani Cardenas, it placed him in the middle of a champagne-like environment of bubblin
Gravity: We might have been getting it wrong this whole timeThe pair then showed how quantum error correcting codes, which explain how three-dimensional gravitational phenomena pop out from two dimensions, like holograms, are not compatible with any symmetry; meaning such symmetry cannot be possible in quantum gra
Why is climate skepticism so successful in the United States?
2019 is set to be the second warmest year on record, ending the warmest decade on record, another reminder that climate change is the defining issue of our time. Yet 2019 will not be remembered as the year when the world finally united to save the planet

While it is widely reported how the world’s rainforests are being chopped down, Wissenschaft reports, “Vegetation on earth has been expanding for decades, satellite data show.”
Yes, the planet is in fact greening, and
Evidence for anisotropy of cosmic accelerationThe observed acceleration of the Hubble expansion rate has been attributed to a mysterious "dark energy" which supposedly makes up about 70% of the universe. Professor Subir Sarkar from the Rudolf Peierls Centre for Theoretical Physics, Oxford along with

Researchers say the discovery could be used to treat osteoarthritis and could one day, with the development of a 'molecular cocktail', allow humans to regrow limbs
