NASA's rover detected macromolecular carbon in clay-bearing sedimentary rock inside Jezero Crater — the strongest organic signature recorded on the Red Planet.
Perseverance detected macromolecular carbon in clay sedimentary rocks inside Jezero Crater.
Organic compounds can form without life, but the geological context adds significance.
Physical samples will be analyzed on Earth via a future NASA-ESA return mission.
Scientists across several countries are investigating why cancer rates are rising among under-50s — and a new study points to accelerated cellular aging as a key factor.
Post-1980 generations show faster cellular aging compared to previous generations at the same age.
Ultra-processed diets, sedentary lifestyles and chronic stress are the main suspected drivers.
Colorectal cancer rates have risen significantly among under-50s over the past two decades.
In 1769, inventor Wolfgang von Kempelen unveiled a chess-playing "automaton" at the Habsburg court in Vienna — a celebrated fraud that defeated Napoleon and inspired a modern tech metaphor.
An artificial intelligence model has lent new weight to a long-contested theory in molecular physics: liquid water may exist in two distinct structural states simultaneously.
An AI model simulated water's molecular behaviour and found evidence for two distinct liquid states.
The two-state theory would explain anomalous properties of water, including its maximum density at 4°C.
Experimental validation is still needed before the findings can be considered established.
A little-known orbital quirk: during the First Quarter phase, the Moon occupies the exact position in its path that Earth held roughly three and a half hours earlier.
At First Quarter, the Moon occupies the orbital position Earth held 3.6 hours earlier.
The effect follows from the Moon's orbital speed and its 90-degree angle to the Sun.
This is a celestial mechanics curiosity with no direct observational effect from the ground.
Scientists at the Popăuți station in Botoșani county have obtained official recognition for Karakul White and Karakul Pink, bringing the breed's certified colour lines to six.
Popăuți station registered Karakul White and Karakul Pink as its own breed creations.
The Karakul breed now has six officially recognised colour lines at the station.
Breed-line certification requires years of genetic selection and scientific documentation.
