Particle Accelerator X-Ray Blasts Help Create Ultra-Slo-Mo 3D Videos

Researchers have come up with a new technique to take 3D X-ray images and even slow-motion movies. The new method could help uncover the internal structure of tiny things, such as viruses and proteins, and shed light on processes that occur at super high speeds, such as the deformation of materials during high speed collisions. The results are reported in a recent paper in the journal Optica.

Scientists May Have Solved the Mystery of "Rogue Waves"

For centuries, sailors have returned to land with tales of being swept up in 100-ft swells, enormous waves appearing from an apparently calm ocean to terrorize even the most stalwart crew members, before sinking into nothingness just as suddenly as they appeared. The mariners who claim to have seen such “rogue waves” were few and far between—but it’s also not the sort of event that vessels can withstand, and there have always been ships lost at sea but never accounted for.

Using Just a Digital Camera, a New Method Lets Scientists See Around Corners

Shadows aren’t usually credited with bringing things to light. They're more often associated with clandestine meetings and dark corners, at least in spy movies. In contrast, new research published today in the journal Nature describes a technique developed by researchers at Boston University that uses shadows to reveal things otherwise hidden from view.

To Measure Gravity, Scientists Drop Individual Atoms

Since interferometry was developed in the 19th century, physics has not been the same. The technique, which relies on manipulating a wave’s path, has been used to measure everything from the speed of light to gravitational waves with remarkable precision. Now, physicists are applying it to an entirely different type of problem: determining the acceleration that matter experiences thanks to the gravitational pull of the Earth.

Bosons and Bubbles: Building a Universe from Scratch

Where did we come from? Where are we going? Why do we exist?

The Controversial "Cow" Explosion

It’s a supernova… It’s a tidal event… It’s a cow?

New Research Turns Tornado Models Upside Down

As we reflect on the best and worst things about 2018, here’s one reason many in the state of Oklahoma are grateful: no one was killed in a tornado last year.

There's an Excessive Amount of Radioactivity in this Middle Eastern Water Supply—but is it Actually Dangerous?

People in Egypt's western desert are drinking groundwater with naturally high levels of radium, a radioactive element, according to research presented last month at the American Geophysical Union meeting in Washington. Experts disagree on the cancer-related health risks, but babies who rely on the most radioactive wells could get more than 100 times the maximum levels recommended by the World Health Organization for long-term exposure from drinking water, according to the researchers. Many communities across the Middle East and northern Africa are likely also using water with elevated levels of radiation.

Starlight and Pink Poo: Studying Penguins from Space

December is behind us, but there's still a lot icy-cold winter left in our part of the world. That means we’re surrounded by snowmen, sleds, and cute little images of penguins and polar bears. This season I’m seeing those penguins in a whole new light, thanks to research presented at the American Geophysical Union’s annual meeting last month.
