When NASA's Perseverance rover touched down in Jezero Crater in February 2021, it carried 10,932,295 names from members of the public, stencilled by electron beam onto three fingernail-sized silicon chips in features thinner than a human hair

Bolted to the aft crossbeam of NASA's Perseverance rover are three fingernail-sized silicon chips carrying 10,932,295 names, etched by an electron beam in features finer than a human hair — a phone book of Earthlings, now sitting in Jezero Crater.

The Roman Space Telescope is designed to pair a wide field of view with infrared vision sharp enough that its surveys can pick up outer solar system objects, exploding stars and growing black holes while mapping galaxies by the billions

The Nancy Grace Roman Space Telescope launched Aug. 30, 2026, carrying a 300-megapixel infrared camera with a field of view 100 times wider than Hubble's — wide enough to survey outer solar system objects, supernovae, feeding black holes and billions of galaxies in the same frame.

What happened when American plains farmers, after a decade of black blizzards burying houses to the eaves in the 1930s, were paid by a new federal agency to plough along the contours and plant windbreak trees?

In April 1935, Congress created the Soil Conservation Service and began paying Great Plains farmers to plough along contours and plant windbreaks. Within seven years, roughly 220 million trees stood in a 1,150-mile shelterbelt from North Dakota to Texas — and the black blizzards began to fade.

Earlier this year France recruited 41 US-based researchers through its Choose France for Science programme, and in August Canada announced 48 more crossing north, as national talent schemes quietly pick off scientists unsettled by US funding cuts

France recruited 41 US-based researchers through its Choose France for Science programme this year, and Canada added 48 more in August, as national talent schemes quietly draw scientists away from an American research system rattled by funding cuts and visa volatility.

Edible

We tend to think honey spoils like any other food, but sealed jars recovered from Egyptian tombs over 3,000 years old have been reported still edible, preserved by a combination of low water content, natural hydrogen peroxide, and a pH acidic enough to stop bacteria from growing at all

Sealed honey pots recovered from Egyptian tombs have been reported edible after 3,000 years — and the chemistry that makes it possible, from bee-added enzymes to water activity below 0.6, still shapes how modern food scientists and mānuka producers think about preservation.
