Engineers predict how flowing fluid will bend tiny hairs that line blood vessels and intestines

Our bodies are lined on the inside with soft, microscopic carpets of hair, from the grassy extensions on our tastebuds, to fuzzy beds of microvilli in our stomachs, to superfine protein strands throughout our blood vessels. These hairy projections, anchored to soft surfaces, bend and twist with the currents of the fluids they're immersed in.

Heating quantum matter: A novel view on topology

Certain quantities appear as integer multiples of fundamental and indivisible elements. This quantization of physical quantities at the heart of our description of nature, made its way through the centuries, as evidenced by the antique concept of the atom. The discovery of quantized quantities has often been associated with a revolution in our understanding of nature's law, a striking example being the quantization of light in terms of photons, which led to our contemporary description of the microscopic world.

Scientists accelerate airflow in mid-air

When a fan blows air across a room, the airflow typically decelerates and spreads out. Now in a new study, scientists have demonstrated the opposite: an airflow created by a carefully controlled ultrasound array can maintain its narrow shape and accelerate as it moves away from the source. The researchers explain that it's as if the airflow is being pushed along by a sequence of invisible fans floating in mid-air. They expect that the accelerating air stream could have unprecedented applications, such as the ability to perform and control chemical reactions in mid-air.

Quick and easy way to shut down instabilities in fusion devices

Scientists have discovered a remarkably simple way to suppress a common instability that can halt fusion reactions and damage the walls of reactors built to create a "star in a jar."

NASA Successfully Launches Latest Communications Satellite

NASA’s Tracking and Data Relay Satellite-M (TDRS-M), which is the third and final in a series of next generation communications satellites, has successfully been placed into orbit following separation from an United Launch Alliance (ULA) Atlas V rocket.

Astronauts Showcase Space Art Created with Childhood Cancer Patients

Patients from around the world will have the opportunity to see a spacesuit art project they helped create.

Engineering team images tiny quasicrystals as they form

What makes quasicrystals so interesting? Their unusual structure. Now scientists are actively pursuing this relatively new area of study.

Researchers found that rotation causes the zig-zag of rising particles

Every curious person must have observed air bubbles rising through an aquarium tank of water.

Superconductivity research reveals potential new state of matter

A potential new state of matter is being reported with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common. The ability to find similarities and differences among classes of materials with phenomena such as this helps researchers establish the essential ingredients that cause novel functionalities such as superconductivity.

Tough, self-healing rubber developed

Imagine a tire that could heal after being punctured or a rubber band that never snapped. Researchers have developed a new type of rubber that is as tough as natural rubber but can also self-heal.
