NASA Geologist and astronaut Harrison Schmitt used an adjustable sampling scoop to retrieve lunar samples during the Apollo 17 mission in 1972.…

Scientists from UC Davis and Cornell University have discovered that applying crushed volcanic rock to croplands can store carbon in soil, even in drought-prone regions like California. This “enhanced rock weathering” could capture up to 215 billion tons of CO2 over 75 years if implemented globally. The technique’s success in arid conditions…

Precise measurements show that Earth’s rotation has been mysteriously slowing down since 2020, making the day longer.Precise astronomical observations, combined with atomic clocks, have revealed that the length of a day is suddenly getting longer. Scientists don’t know why.This has critical impacts not just on our timekeeping, but also on things…

Here on Hackaday, we routinely cover wonderful informative writeups on different areas of hardware hacking, and we even have our own university with courses that delve into topics one by one. I’ve had my own fair share of materials I’ve learned theory and practical aspects from over the years I’ve been hacking – as it stands, for over…

The universe's most massive known star just got its best ever close-up, and it reveals the star might be smaller than astronomers previously thought.Astronomers using the Gemini South telescope in Chile photographed the star R136a1, which is located about 160,000 light-years from Earth in the center of the Tarantula Nebula in the Large…

Daran-Lapujade’s lab took human DNA (in red) encoding core functions in muscle cells and inserted it into the DNA (chromosomes in purple) of a yeast cell (in yellow). The humanized yeast can be used as a tool for medical studies, for example in drug screening and cancer research. Credit: Ella Maru Studio / Pascale Daran-LapujadeDelft University…

In an extraordinary feat of engineering and international collaboration, the Orion spacecraft, a part of NASA’s Artemis I mission, has achieved a remarkable milestone in space exploration. The spacecraft ventured some 267,000 miles from Earth and roughly 40,000 miles from the Moon, surpassing the distance record set by the Apollo 13 mission over…

The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12) have been confirmed using the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). The galaxies are located in Pandora’s Cluster (Abell 2744), show here as near-infrared wavelengths of light that have been translated to visible-light colors. The scale…

The recent “Hubble tension” in cosmology, marked by conflicting expansion rate measurements, raises questions about the standard cosmological model. A new theory posits that a giant, underdense void could account for these discrepancies, challenging traditional views of matter distribution in the universe and suggesting a potential overhaul of…

The Tasmanian tiger could be reintroduced into the wild within a decade after a US biotechnology company backed by the Winklevoss twins pledged to recreate the animal almost 90 years after it was declared extinct.The last thylacine, the official name of the Tasmanian tiger that was the Australian island’s apex predator, died in a zoo in…
