A new safety-check technique can prove with 100 percent accuracy that a planned robot motion will not result in a collision. The method can generate a proof in seconds and does so in a way that can be easily verified by a human.

Scientists can make high resolution images of the human spinal cord during surgery. The advancement could help bring real relief to millions suffering chronic back pain.

A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.

Researchers have used machine learning to create a model that simulates reactive processes in organic materials and conditions.

Scientists have developed an optical display based on mechano-optical mechanisms.

At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.

Physicists are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits 'fly'.

A research team has reported a groundbreaking development in efficient hydrogen storage.

Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.

Engineers developed a cathode material for lithium-sulfur (Li-S) batteries that is healable and highly conductive, overcoming longstanding challenges of traditional sulfur cathodes. The advance holds promise for bringing more energy dense and low-cost Li-S batteries closer to market.

Researchers have developed a semiconductor chip that will enable ever-smaller devices to operate at the higher frequencies needed for future 6G communication technology.

An updated method for directly observing physical interactions between cells, could allow scientists to one day map every possible cell interaction.

Precision timing and synchronization are crucial for navigation, communication and radar systems. Scientists have built compact chips capable of converting light into microwaves, which could improve these systems. This technology shrinks a tabletop system into a chip-sized format, reducing power usage and making it more applicable for use in everyday devices.

A new tool captures data from an unprecedented 1 million neurons simultaneously, painting a much fuller picture of brain dynamics.

A groundbreaking nanosurgical tool -- about 500 times thinner than a human hair -- could be transformative for cancer research and give insights into treatment resistance that no other technology has been able to do, according to a new study.

A type of nanoparticle called a metal organic framework (MOF) could be used to deliver vaccines and act as an adjuvant. Researchers find these particles provoke a strong immune response by activating the innate immune system through cell proteins called toll-like receptors.

Unmanned Aerial Vehicles (UAVs) are beneficial in search and rescue missions during natural disasters like earthquakes. However, current UAVs depend on visual information and cannot detect victims trapped under rubble. While some studies have used sound for detection, the noise from UAV propellers can drown out human sounds. To address this issue, researchers have developed a novel artificial intelligence-based system that effectively suppresses UAV noise and amplifies human sounds.

A world-leading device developed by researchers to measure faulty gut electrical signals has passed a major milestone.

Chemists are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.

A nanotechnology pioneer has uncovered a transformative approach to harnessing the catalytic power of aluminum nanoparticles by annealing them in various gas atmospheres at high temperatures.
