Deep in coastal mud and shallow lagoons, a tiny, brainless sea anemone is quietly using the same molecular playbook that helps human embryos decide where to put a back and a belly. A new study from the University of Vienna shows that the starlet sea anemone Nematostella vectensis builds its body using a signaling system
It was a groundbreaking discovery. Scientists have found previously concealed fault lines along California’s north coast, sparking concerns that we could be drastically underestimating the earthquake risk in the region, per a seismic study published in the journal “Science.” “If we don’t understand the underlying tectonic processes, it’s hard to predict the seismic hazard,” declared study

Archaeologists in Greece have discovered 430,000-year-old handheld wooden tools, the oldest surviving examples of their kind in the world, a new study finds. The two tools, found on the Peloponnese peninsula in southern Greece, were created by an unidentified hominin species that predates modern humans. “The objects represent the oldest hand-held wooden tools ever found,
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday. The treasure trove of fossils offers a rare glimpse into a cataclysmic event that brought a sudden end to the greatest explosion of life in our
Russia is quietly testing a new plasma propulsion system that, if it performs as claimed, could dramatically change how long it takes to travel to Mars. Early results suggest a leap in speed and efficiency that has drawn attention precisely because it is not coming from NASA or private U.S. companies such as SpaceX. The
Researchers using the James Webb Space Telescope have found a galaxy that is offering new data about the early stages of the universe’s existence. The latest discovery shared by astronomers is about a bright galaxy dubbed MoM-z14. According to the team, this galaxy existed 280 million years after the Big Bang. The sounds like a
A Stone Age person buried 12,000 years ago in a cave in Italy had a rare genetic disorder that shortened her arms and legs, a new study finds. A DNA analysis of her skeleton revealed that she was a teenage girl who had a rare form of dwarfism. The finding is the earliest DNA diagnosis
NASA has announced an earlier-than-expected target date to launch the next astronauts to the International Space Station (ISS). The agency is now targeting Feb. 11 for liftoff of the SpaceX Crew-12 mission, which will fly four astronauts to join the skeleton crew presently operating the orbital lab. A scant three are currently covering the maintenance
NASA is preparing to move forward with a key milestone as it readies the Space Launch System (SLS) rocket and Orion spacecraft for the Artemis II mission. A “wet dress rehearsal” allows launch teams to practice fueling and countdown procedures under conditions that closely mirror launch day, much like a full dress rehearsal before a
