For decades, they lay untouched and largely forgotten—hundreds of thousands of barrels filled with radioactive waste, scattered across the abyssal plains of the Atlantic Ocean. Now, more than 30 years after the last were submerged, a French scientific mission is preparing to search for them, raising fresh questions about the long-term impact of nuclear dumping at sea.

The Tesla logo is one of the most recognizable symbols in the automotive world. Sleek, minimalist, and futuristic, it sits on the front of every electric vehicle made by the California-based company.

On social media platforms such as Reddit, users have questioned the true shape of the logo, sparking a flurry of speculation.

In a laboratory in Kyoto, a team of geneticists made a small but significant tweak to the DNA of mice. Using CRISPR gene-editing technology, they inserted a single variant of a gene once carried by Homo neanderthalensis and Denisovans—archaic relatives of modern humans—into the genomes of living rodents. The mice, raised under controlled conditions, soon began to show signs of anatomical differences that echoed the skeletal structure of these extinct hominins.

Deep in the parched terrain of western Namibia, geologists have found something that challenges long-held assumptions about the Earth’s crust. Lining the inside of ancient marble formations are countless hair-thin tunnels, running perfectly parallel to one another for as long as ten meters. Carved into rock that dates back over half a billion years, these micro-burrows raise a confounding question: What could have created them?

The Step Pyramid of Djoser, constructed around 2680 BC, may not have relied solely on manpower and primitive tools as long believed. Instead, researchers suggest the monument rose block by block through the aid of a sophisticated hydraulic lift system, fed by water redirected from nearby wadis.
