Every year a Chinese-dominated flotilla big enough to be seen from space pillages the rich marine life on Mile 201, a largely ungoverned part of the South Atlantic off Argentina

In a monitoring room in Buenos Aires, a dozen members of the Argentinian coast guard watch giant industrial-fishing ships moving in real time across a set of screens. “Every year, for five or six months, the foreign fleet comes from across the Indian Ocean, from Asian countries, and from the North Atlantic,” says Cdr Mauricio López, of the monitoring department. “It’s creating a serious environmental problem.”

Just beyond Argentina’s maritime frontier, hundreds of foreign vessels – known as the distant-water fishing fleet – are descending on Mile 201, a largely ungoverned strip of the high seas in the South Atlantic, to plunder its rich marine life. The fleet regularly becomes so big it can be seen from space, looking like a city floating on the sea.

There’s nothing more uplifting than hearing about a world-shaking, life-enhancing new development. But science shouldn’t overlook the small stuff, or stop looking for new species of cute, fluffy mammals …

People who greet the new year with hope, ambitious plans and optimised gut microbiomes might be obnoxiously apparent at the moment, but we all know they’re a minority. Most of us lurched into 2026 catastrophically depleted and grey-faced, juggling deep Lemsip dependency with a deeper overdraft and a sense of ever-deepening global geopolitical foreboding. There is, however, one thing that fills me with buoyant optimism now and always: science. I don’t understand it, but I’m delighted it’s out there, making things better.

I was booted out of my leaden year-end listlessness by The Atlantic’s list of 55 Facts That Blew Our Minds in 2025. Did you know, for example, that scientists at UC Berkeley created a new colour? (It’s called “olo” and it’s sort of teal.) Or that doctors treated a baby with a rare genetic disorder with custom gene editing? There were more wonders in the Smithsonian’s list of last year’s fascinating scientific discoveries: ichthyosaurs, extinct marine reptiles, had “stealth flippers”, snails can regrow eyes within a month, and “flamingos form tornado-like vortices as they probe for prey”, which is pure poetry (it looks pretty cool too, I watched one do it on YouTube). Still on an animal theme, entomologists discovered a “bone collector” caterpillar that conceals itself in the body parts of its prey (I’m sure he’s lovely when you get to know him). 2025 was also the year science made oyster mushrooms play keyboards (sort of), astronomers discovered more than 100 moons in our solar system and medical researchers created replica womb lining and made astonishing progress towards lab-grown teeth.

Exclusive: data reveals hundreds of UK nests have been raided in the past decade amid growing appetite to own prized birds for racing and breeding

In the echoing exhibition halls of Abu Dhabi’s International Hunting and Equestrian Exhibition, hundreds of falcons sit on perches under bright lights. Decorated hoods fit snugly over their heads, blocking their vision to keep them calm.

In a small glass room marked Elite Falcons Hall, four young birds belonging to an undisclosed Emirati sheikh are displayed like expensive jewels. Entry to the room, with its polished glass, controlled lighting and plush seating, is restricted to authorised visitors only.

Guardian writers and readers share the simple tricks they use to bring a bit of joy into their lives

During the pandemic, my husband found some wood on our street and used it to build a tiny, squirrel-sized picnic table. We attached it to the side of our fence with a handful of peanuts on top. Few sights are guaranteed to lift my day more than watching a “dining in” Nutkin parking its rump on the tiny wooden seat, occasionally glancing towards the house as if he’s waiting for you to bring the drinks. If you don’t have as much time on your hands as my husband did during lockdown, you can buy one on Etsy.

A helpless baby elephant has won the Thai public’s sympathy but her case has shed light on the pressures facing herds across Asia

Khao Tom, a two-month-old elephant, plays with a wildlife officer, nudging his face and curling her trunk around his wrist. When she lifts her trunk in the air, signalling that she is hungry, the team at the rescue centre seems relieved – she has not been eating well. A vet prepares a pint-sized bottle of formula, which she gulps down impatiently.

Khao Tom has been in the care of Thailand’s national parks and wildlife department since September, when rangers rescued her from a farming area inside Lam Khlong Ngu national park. Born with a congenital disorder affecting her knees, she struggled to keep up with the herd. Within days of her birth, her mother had moved on without her.
