Nanozymes map nanoparticle routes inside live cells without genetic engineering

Nanoparticles are widely used in medicine to deliver drugs, genes or imaging agents to specific parts of the body. Once a nanoparticle reaches a cell, however, many things can happen—it can reach its target, be degraded, interact with proteins that help transport it, or interact

Bomb the Arctic, dam the Mediterranean and build a second moon: five outlandish plans to r

Humans have long sought to geoengineer the Earth’s environment. Tim Flannery outlines a few of the wildest ideas from the 20th centuryAn increasing number of scientists think we have let the climate crisis fester for so long that our only hope to stave off ever-intensifying catas

An island of calm at the violent heart of the galaxy

Where would you go to watch a star being born? Probably not the heart of the Milky Way, which is about the most violent neighborhood our galaxy has to offer, a maelstrom of gas churning so fast and so chaotically that you would think nothing could ever settle there long enough to

A new net-membrane could clean up some tricky space debris

We've reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keep

Evidence of elusive high-energy gravitons in quantum Hall systems

Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are confined to a ve

New ultrathin lens focuses light into an optical needle

Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence tomography (OCT) could allow imaging that reaches deeper

Nature's puncture tools reveal shape trade-offs between piercing power and strength

Nature has invented countless types of pointy appendages, and scientists have long sought to explain what makes these structures so effective at puncturing other things. A new study models the key physical characteristics of puncturing tools to reflect their diversity in nature,

Low-e windows keep homes cool … but may set neighbours’ property on fire

Low-emissivity windows also keep houses warm in winter, but use on bowed glass can have magnifying-glass effectLow-emissivity or low-E window glass is a useful green technology for keeping buildings warm in winter and cool in summer … but a rare side-effect can set the neighbours

Country diary: The field names here read like a history book | Eben Muse

Ynys Enlli, Gwynedd: A stroll down this island’s one road provides clues to its past – and it has nothing to do with the 20,000 saints apparently buried hereIn 1938, the Welsh naturalist Ronald Lockley described Ynys Enlli (Bardsey Island) as a mountain “crudely cemented to a low

AI can predict how you'll respond to a survey—but that's not the same as understanding you

What makes people change their minds or their behavior? Social scientists spend a lot of time thinking about this question, and experiments are one of the most powerful ways to answer it.
