A team of researchers has identified a promising new approach that may one day help to restore vision in people affected by macular degeneration and other retinal disorders.

Researchers developed a machine-learning-guided technique to solve complex, long-horizon planning problems more efficiently than some traditional approaches, while arriving at an optimal solution that better meets a user's goals.

A recently created RoboBee is now outfitted with its most reliable landing gear to date, inspired by one of nature's most graceful landers: the crane fly. The team has given their flying robot a set of long, jointed legs that help ease its transition from air to ground. The robot has also received an updated controller that helps it decelerate on approach, resulting in a gentle plop-down.

A researcher has developed an autonomous driving algorithm for agricultural robots used for greenhouse cultivation and other farm work.

A research team develops a new alloy that maintains tensile properties from -196 degrees Celsius to 600 degrees Celsius.

Crime scene investigation may soon become significantly more accurate and efficient thanks to a new method for detecting gunshot residues. Researchers have developed the technique that converts lead particles found in gunshot residue into a light-emitting semiconductor. The method is faster, more sensitive, and easier to use than current alternatives. Forensic experts at the Amsterdam police force are already testing it in actual crime scene investigations.

There's a sensation that you experience -- near a plane taking off or a speaker bank at a concert -- from a sound so total that you feel it in your very being. When this happens, not only do your brain and ears perceive it, but your cells may also. Technically speaking, sound is a simple phenomenon, consisting of compressional mechanical waves transmitted through substances, which exists universally in the non-equilibrated material world. Sound is also a vital source of environmental information for living beings, while its capacity to induce physiological responses at the cell level is only just beginning to be understood.

By the 2060s, some airports with shorter runways may need to reduce their maximum take-off weight by the equivalent of approximately 10 passengers per flight during summer months.

When two materials come into contact, charged entities on their surfaces get a little nudge. This is how rubbing a balloon on the skin creates static electricity. Likewise, water flowing over some surfaces can gain or lose charge. Now, researchers have harnessed the phenomenon to generate electricity from rain-like droplets moving through a tube. They demonstrate a new kind of flow that makes enough power to light 12 LEDs.

A team of researchers has successfully predicted abnormal grain growth in simulated polycrystalline materials for the first time -- a development that could lead to the creation of stronger, more reliable materials for high-stress environments, such as combustion engines.

Engineers have developed a building material that uses the root-like mycelium of a fungus and bacteria cells. Their results show that this material -- which is manufactured with living cells at low temperatures -- is capable of self-repairing and could eventually offer a sustainable alternative for high-emission building materials like concrete.

A bioreactor that mimics a circulatory system can deliver nutrients and oxygen to artificial tissue, enabling the production of over 10 grams of chicken muscle for cultured meat applications.

Physicists have created a compact laser that emits extremely bright, short pulses of light in a useful but difficult-to-achieve wavelength range, packing the performance of larger photonic devices onto a single chip.

Scientists have designed a 'cosmic radio' detector which could discover dark matter in 15 years.

Switching from diesel to electric trains dramatically improved the air quality aboard the San Francisco Bay Area's Caltrain commuter rail line, reducing riders' exposure to the carcinogen black carbon by an average of 89%, finds a new study. The electrification of the system also significantly reduced the ambient black carbon concentrations within and around the San Francisco station.

Imagine tiny building toy pieces that automatically snap together to form a strong, flat sheet. Then, scientists add special chemical 'hooks' to these sheets to attach glowing molecules called fluorophores. Researchers have created these tiny, clay-based materials -- called fluorescent polyionic nanoclays. They can be customized for many uses, including advancing energy and sensor technology, improving medical treatments and protecting the environment.

In 2021, Major League Baseball banned the usage of resin, and since batting averages have gone up. A group of researchers set out to reveal the science behind this.

A new study could lead to more widespread use of imaging technique to improve survival and prevent complications.

A team has developed an explainable AI model for automatic collision avoidance between ships.

Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centeres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.
