Genetically engineered crops are nothing new. But emerging technology that allows scientists to alter plants more precisely and cheaply is taking genetically engineered plants from the field to the kitchen.

The first version of the Arctic Apple, a genetically modified Golden Delicious, is headed for test markets in the Midwest in February, according to the company that produced it. It is the first genetically engineered apple, altered so that when it is cut, it doesn't turn brown from oxidation.

An archaeologist has launched a citizen science project that invites anyone with an Internet connection to help look for evidence of archaeological site looting.

This week, President Trump's transition team put new restrictions on government scientists' freedom to communicate. The restrictions are being characterized as temporary, and some have already been lifted.

Biologist Shaun Clements stands in the winter mist in a coastal Oregon forest. He’s holding a small vial of clear liquid.

“We should be safe mixing it now, right?” he asks his colleague Kevin Weitemier above the sound of a rushing stream a few feet away.

Weitemier brings a second vial, full of stream water. In deliberate, seeming choreographed movements, usually associated with ritual, they pour the liquid back and forth between the small containers to mix -- two, then three times — never spilling a drop.

Clements looks down at the clock. It’s 12:29 pm.

The first results from a major project to measure the reliability of cancer research have highlighted a big problem: Labs trying to repeat published experiments often can't.

That's not to say that the original studies are wrong. But the results of a review published Thursday, in the open-access journal eLife, are a sobering reminder that science often fails at one of its most basic requirements — an experiment in one lab ought to be reproducible in another one.

Last year, global warming reached record high temperatures — and if that news feels like déjà vu, you're not going crazy.

The planet has now had three consecutive years of record-breaking heat.

If it sometimes seems like the idea of antibiotic resistance, though unsettling, is more theoretical than real, please read on.

Public health officials from Nevada are reporting on a case of a woman who died in Reno in September from an incurable infection. Testing showed the superbug that had spread throughout her system could fend off 26 different antibiotics.

In a tiny island laboratory in the Northwesternmost corner of Washington, one marine biologist is on a mission: scan every known fish species in the world.

It’s a painstaking and smelly task, but one that promises to fundamentally change the way scientists and educators look at marine anatomy.

A comparison of kid brains and grownup brains may explain why our ability to recognize faces keeps getting better until about age 30.

Brain scans of 25 adults and 22 children showed that an area devoted to facial recognition keeps growing long after adolescence, researchers report in the journal Science.

The 24 juniors and seniors in the astronomy class at Thomas Jefferson High School in Alexandria, Va., sink into plush red theater seats. They're in a big half-circle around what looks like a giant telescope with a globe on the end. Their teacher, Lee Ann Hennig, stands at a wooden control panel that has enough buttons and dials to launch a rocket.

Kim Malcolm talks with Sam Sommers about the science behind why we root for underdogs in sports. Sommers is associate professor of psychology at Tufts University and co author of "This is Your Brain on Sports."

Terrorist attacks, hurricanes, a divisive U.S. election, Brexit — 2016 has not been easy. With the year coming to an end, we thought it was time to get some serious perspective — from the scale of the entire universe.

We're tackling big questions: what scientists know, and what they have yet to learn.

So before you ring in another year, take a moment to contemplate the billions of years that led to 2017 and the billions more yet to come.

Here's a timely reminder for all you would-be revelers out there: Be careful with your countdowns this New Year's Eve. There will be a little extra time to bask in the glow of a retreating 2016 — or curse its name, as the case may be.

Whatever your inclination may be, one thing is certain: Before the year is out, the world's foremost authority on time will be adding one more second to the clock.

Vera Rubin, the groundbreaking astrophysicist who discovered evidence of dark matter, died Sunday night at the age of 88, the Carnegie Institution confirms.

Rubin did much of her revelatory work at Carnegie. The organization's president calls her a "national treasure."

In the 1960s and 1970s, Rubin was working with astronomer Kent Ford, studying the behavior of spiral galaxies, when they discovered something entirely unexpected — the stars at the outside of the galaxy were moving as fast as the ones in the middle, which didn't fit with Newtonian gravitational theory.

This winter brings the latest installment of the Star Wars franchise, full of familiar costumes, familiar villains, and the familiar "pew pew pew" of space guns. But you can skip the movie theatre and still hear those iconic blaster sounds if you visit a frozen lake.
