Theoretically, it’s impossible for us to perceive a 4D creature. That is, unless it broke into our three-dimensional reality.
These could be incredibly valuable to future astronauts hoping to settle on the moon, acting as a convenient shelter for a lunar base.
The cave is accessible through a pit in the well-studied Mare Tranquillitatis (Sea of Tranquility). This is a large basin made mostly of basalt. Neil Armstrong and Buzz Aldrin touched down in this region on July 20 1969.
While Mare Tranquillitatis isn’t likely to be the first place humans try to settle on the moon, the existence of one cave makes the existence of others very likely, so scientists now expect there to be others in locations more suitable for human settlement.
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds.
In an unexpected turn of events, a two-week archaeological dig unearthed a remarkably intact mastodon skull in a creek that might carry signs of human life too.
Over twelve days, archaeologists unearthed several mastodon bones. However, the skull, being “the first-ever well-preserved” artifact of its kind, makes it a significant find with potential connections to human history.
“We’re really hoping to find evidence of human interaction with this creature — perhaps the projectile points and knives that were used to kill the animal and do initial butchering,” John Doershuk, director and state archaeologist at the University of Iowa Office of the State Archaeologist (OSA) said.
The science writer and journalists talks identity politics, wokeness, trans athletes, and why his goal is to find out what is true rather than to \.
UC biologist Joshua Gross studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. In a study, supported by the National Science Foundation, Gross looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.
People whose eyes dilated more performed better on tests of working memory.
Microscope images could be obtained much more quickly—rather than one pixel at a time—thanks to a new imaging method for neutral atomic beam microscopes developed by Swansea University researchers. It could ultimately lead to engineers and scientists getting faster results when they are scanning samples.
Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.
Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.
