Developments in science that we’re still thinking about at year end.

It’s not easy to say that any particular space or astronomy development was the most important in a given year. But if we had to choose some highlights, we’d opt for these unforgettable events and findings.

You probably know the broad outline of the story: million years ago, a giant meteorite landed in what is now the Gulf of Mexico, and ended the dinosaurs . This year, various teams of scientists, working independently, helped fill in the picture of exactly what happened on that fateful day.

The largest discovery was a site in North Dakota that preserved a jumble of fossilized fish and plant life that may have been thrown together by a tsunami

that day. And researchers detailed evidence found in Europe that the Chicxulub eventacidified the ocean in a flash

, extinguishing much of Earth’s ocean life at the time.

An exhaustive analysis of hundreds of bird species in the United States and Canada contained a warning: The majority of bird species are in decline, many by huge numbers. The likely culprits? Habitat loss and pesticides.Quantum computing changed everything and nothing

This year we met a new extinct human relative, Homo luzonensis. It was discovered in a cave on Luzon Island in the Philippines, and adds further complexity to the story of human evolution.

Almond milk is over. Oat milk is canceled. What’s in? Spider milk. Burying beetle milk. Great white shark milk. Flamingo milk. Which raises the question: what exactly is milk? Not all experts agree, but some scientists say that if a substance is synthesized or highly modified by a parent, and the offspring’s life depends on it,this milk. Now excuse us while we put out cookies and pink flamingo milk for Santa. (********************************** (There really is a 5G conspiracy

At home, Russia, like the United States and other countries around the world, has embraced the promise of 5G, the next generation of cellphone technology. But in the U.S., RT America, the broadcast network run by the Russian government, has been warning American viewers that the telecommunications technology will kill and disable children. Many alarming claims about 5G technology arelinked to bad, debunked science. The U.S. intelligence agencies describe RT America as “the Kremlin’s principal international propaganda outlet.” The network has taken aim at fracking, vaccination and even the U.S. electoral process; now it has applied its playbook to cellphones.

The North Pole is at the very top of the world, right? Actually, the planet’s magnetic north is a great distance from degrees north, and it moves around. Lately it has moved more than expected, requiring scientists to update the World Magnetic Model a year earlier than planned. The tinkering ensures that modern navigation tools will continue to function properly, but it is a reminder of the geoscience mysteries deep beneath Earth’s surface.
