Asian paper wasp nests take on a new verdant glow under ultraviolet light.

Wasp Nest Glows Green Under UV Light

Silk fibers give the nest its radiant a neon hue

A 3D image of the spiral-shaped intestine of a Pacific spiny dogfish shark. In life, food would move through this intestine left to right.

Sharks' Intestines Spiral Like a Valve Invented by Nikola Tesla

Tesla's ingenious valve promoted a one-way flow of fluid without the need for moving parts, but, it turns out, evolution got there first

The researchers flew their fridge on parabolic flights to simulate a microgravity environment.

The Quest to Build a Functional, Energy-Efficient Refrigerator That Works in Space

Designed and tested by Purdue University engineers, this new appliance would lengthen the shelf life of food on long missions

A new image of a powerful jet firing out of the black hole at the center of the radio galaxy Centaurus A, taken with the Event Horizon Telescope.

New Black Hole Image Shows Plasma Jets Blasting Into Space

Researchers say the new, detailed image of the black hole at the center of the Centaurus A galaxy could reveal how its jets formed

A thin strand of ice seen through a microscope in the process of bending under pressure. When the pressure is released the ice strand will spring back to its original shape.

Scientists Make Thin Strands of Ice That Bend Without Breaking

Researchers created a new type of ice that is far more elastic than any other water ice ever studied

This sample of red trinitite contained the quasicrystal described in a new study.

Study Plucks Rare Quasicrystal From Wreckage of First Atomic Bomb Test

Researchers found the strange material inside a piece of red trinitite, a glass-like amalgam formed by the blast's intense heat and pressure

Remnants of a supernova called Cassiopeia A, located in our galaxy about 11,000 light-years from Earth. Scientists have long thought that supernovae were responsible for the creation of the heaviest elements, but new research suggests other types of stellar events may also be in play.

Scientists Find Plutonium Made in Outer Space on Ocean Floor

Research suggests the rare, heavy element may have been created by the collision of two neutron stars

So far, scientists have only documented jagged lightning bolts. Some physicists believe that the discovery of a completely straight lightning bolt could prove the existence of dark matter.

Could Weirdly Straight Bolts of Lightning Be a Sign of Dark Matter?

A group of scientists say the phenomenon could indicate dark matter speeding through our world at more than 300 miles a second

Researchers used A.I. to reconstruct the likely colors and brushstrokes of this landscape, which Pablo Picasso painted over to create a 1902 portrait.

Scientists Used A.I. to Recreate a Landscape Hidden Beneath a Picasso Painting

Physical reconstructions of the early 20th-century depiction of Barcelona are now on sale for $11,111.11 each

The 50-foot-wide racetrack used to study muons traveled by barge around Florida and up the Mississippi, and then by truck across Illinois.

New Measurements of Muons Might Rewrite Particle Physics

The gap between theoretical predictions and the experimental measurements isn’t a full-blown discovery yet

Albert Einstein arrived in New York on the SS Rotterdam IV; crowds of people awaited his arrival in the States.

One Hundred Years Ago, Einstein Was Given a Hero's Welcome by America's Jews

The German physicist toured the nation as a fundraiser for Zionist causes, even though he was personally torn on the topic of a Jewish nation

This is an atomic clock that uses the predictable frequency of ytterbium atoms absorbing and emitting light to tell time. A new experiment paired a ytterbium-based atomic clock with two others that used aluminum and strontium atoms, respectively, to create an even more accurate measure of time.

New Atomic Clocks May Someday Redefine the Length of a Second

Researchers used three atomic clocks to measure time accurately down to the quadrillionth of a percent

As the largest telescope in the Northern Hemisphere, the research team says it can rival the IceCube Neutrino Observatory in the South Pole.

Russian Scientists Sink Giant Deepwater Neutrino Telescope Into World's Largest Freshwater Lake

In the depths of Lake Baikal, the observatory is designed to detect nature's ghost particles

An illustration based on the satellite observation data from the first confirmed instance of a space hurricane.

First Ever Space Hurricane Spotted in Earth's Upper Atmosphere

The 600-mile-wide swirling cloud of charged particles rained down electrons from several hundred miles above the North Pole

When the two microflyers twirled around eachother midair, the researchers dubbed the maneuver "The Tango."

New Microflyers Could Soar in the Atmosphere's Most Mysterious Layer

The mesosphere is too dense for satellites to orbit there, but too thin for planes and balloons to fly

Chien-Shiung Wu received numerous awards and honors throughout her life, including having an asteroid named after her in 1973 and receiving the National Medal of Science in 1975.

U.S. Postage Stamp Will Honor the 'First Lady of Physics'

Chien-Shiung Wu’s experiment in 1956 helped her colleagues win the Nobel Prize while her role was only mentioned in the acceptance speech

The "jaws" of the carnivorous Venus flytrap plant are actually modified leaves.

Magnetic Fields Detected in Venus Flytraps

Researchers used sensitive instruments to measure weak magnetic fields when the flytrap's 'jaws' closed up

A group of perovskite solar cells that have been treated with capsaicin.

Chili Pepper Compound Increases Solar Cell Efficiency

Adding capsaicin, the chemical responsible for making chili peppers spicy, improved the efficiency of solar cells in experiments

"Yellowknife Flurry," a photograph by Nathan Myhrvold, captures the intricate structure of snowflakes.

These Are the Highest-Resolution Photos Ever Taken of Snowflakes

Photographer and scientist Nathan Myhrvold has developed a camera that captures snowflakes at a microscopic level never seen before

Newton held unconventional religious beliefs and dabbled in alchemy and the occult.

Isaac Newton Thought the Great Pyramid Held the Key to the Apocalypse

Papers sold by Sotheby's document the British scientist's research into the ancient Egyptians and the Bible
