The possible multistage journey suggests remarkable organization and raises the possibility that the stone was valued long before it became part of Stonehenge. Wed, 23 Sep 2026 06:26:41 EDT https://www.sciencedaily.com/releases/2026/09/260922005715.htm https://www.sciencedaily.com/releases/2026/09/260922005712.htm Some tropical trees have evolved a clever way to survive drought by taking in carbon dioxide at night, allowing them to keep their pores closed during the hot daytime and conserve water. By comparing three Clusia species, researchers discovered that this water-saving form of photosynthesis, known as CAM, did not arise through a single evolutionary change. Instead, ancient genome duplications followed by millions of years of genetic reshuffling produced strikingly different strategies, from strong CAM to stress-triggered and hybrid forms.

Positively charged metal ions appear to bridge the gap, helping matching DNA helices align groove for groove like a molecular zipper. The discovery confirms a theory proposed two decades ago and could help researchers understand DNA interactions involved in cancer and other cellular processes.

Researchers found both unusual tooth wear and traces of arecoline, the nut’s mind-altering compound, in the teeth of prehistoric hunter-gatherers. The practice may have started partly as pain relief for toothaches, but prolonged use severely damaged their teeth. The discovery could represent the earliest known evidence of habitual drug use anywhere in the world.

Only 6.6% of surveyed experts thought possible biological molecules on K2-18b probably represented extraterrestrial life, while 15.1% said the same about intriguing mineral patterns in a Martian rock.

Scientists found protein mutations suggesting several East Asian Homo erectus populations belonged to the same evolutionary group, including one mutation previously associated with Denisovans. That variant may have passed from Homo erectus into Denisovans and eventually reached modern populations in Southeast Asia and Oceania.

The discovery reveals an astonishing feat of prehistoric engineering and suggests the stones’ distant source may have been chosen for cultural or spiritual reasons.

Monash University researchers have developed a global framework to close this gap by combining scientific studies with museum collections, local expertise, citizen science, social media records, and new technologies.

Their magnetic signatures show that major tectonic deformation had already weakened by the late Miocene, suggesting the most intense collision occurred earlier than previously believed.

In lab tests, the mixtures were about 10 times more potent than a current commercial antivenom, pointing toward a new generation of nature-inspired snakebite treatments.

Fossils from the Yukon suggest northern populations survived partly by eating fish, possibly including salmon, while southern cats hunted on land.
