SpaceX is set to launch the first human spaceflight directly over Earth's polar regions on Monday—a days-long, privately funded orbital mission involving four astronauts.
The surface of Mars is known for being an extremely cold, desiccated, and irradiated place. But as its many surface features attest, the red planet was once a warmer, wetter place with flowing water and glaciers. Today, most ...
Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and consist of an array of tiny ...
Scientists have revealed how tiny swimming cells—such as sperm and bacteria—are able to move faster when traveling as a group, and the research could accelerate the development of microscopic robots that deliver drugs ...
How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon. But the world is messier than a textbook.
When materials are created on a nanometer scale—just a handful of atoms thick—even the thermal energy present at room temperature can cause structural ripples. How these ripples affect the mechanical properties of these ...
In a crowded room, we naturally move slower than in an empty space. Surprisingly, worms can show the exact opposite behavior: In an environment with randomly scattered obstacles, they tend to move faster when there are more ...
Imagine if a doctor could remotely do a non-invasive, highly precise medical procedure on her patients using a tiny robot, or microrobot. With a device researchers from SMU and George Washington University created, that is ...
"Did you see that?" It is a simple phrase we hear every day, but how do we know what "that" refers to? A new study from Kyushu University, published in PLOS One, reveals that children and adults use different strategies to ...
A study focusing on analyzing cell models found universality in their movement—an important discovery that could impact both health and robotics.
