Johns Hopkins engineers have created a new lens-free ultra-miniaturized endoscope, the size of a few human hairs in width, that is less bulky and can produce higher quality images.

Scientists report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size -- even hefty ones attached to the gene-editing tool called CRISPR.

Gel-like materials have a wide range of applications, especially in chemistry and medicine. However, their usefulness is sometimes limited by their inherent random and disordered nature. Researchers have found a way to produce a new kind of gel which overcomes this limitation. It is still malleable and adaptable like existing gels, but it has a more ordered structure, which can open up a new range of possible uses in various fields.

A physicist has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser.

The creation of photoelectrons through ionization is one of the most fundamental processes in the interaction between light and matter. Yet, deep questions remain about just how photons transfer their linear momentum to electrons. With the first sub-femtosecond study of the linear photon momentum transfer during an ionization process, physicists now provide unprecedented insight into the birth of photoelectrons.

Researchers have demonstrated the first material that can have both strongly correlated electron interactions and topological properties, which not only paves the way for more stable quantum computing but also an entirely new platform to explore the wild world of exotic physics.

A team of researchers studying new methods to remove toxic heavy metals from biosolids -- the solid waste left over after sewage treatment -- found the key is a brief spin through a microwave.

A team of computer science professors created a method to quickly resize animations of fluids without having to completely re-simulate the entire sequence.

Nuclear physics usually involves high energies, as illustrated by experiments to master controlled nuclear fusion. One problem is how to overcome the strong electrical repulsion between atomic nuclei which requires high energies to make them fuse. But fusion could be initiated at lower energies with electromagnetic fields that are generated by state-of-the-art free electron lasers emitting X-ray light. Researchers describe how this could be done.

A research team has reported seeing, for the first time, atomic scale defects that dictate the properties of a new and powerful semiconductor. The study shows a fundamental aspect of how the semiconductor, beta gallium oxide, controls electricity.

A group of scientists has taken inspiration from the field, kitchen and the ocean to create strong glues.

Technology 'squeezes' out quantum noise so more gravitational wave signals can be detected.

Early returns from the US Naval Research Laboratory's camera on NASA's latest mission to study the Sun's corona revealed on Dec. 4 a star more complex than ever imagined.

Toxic substances from agriculture, industry and households endanger water quality in Europe -- and by extension, ecosystems and human health. As part of the SOLUTIONS project, over 100 international scientists have developed methods and practical solutions for identifying pollutants and assessing the risks posed by chemical cocktails. This is intended to help reduce pollution in water resources. Researchers have described how politicians can implement these scientific results in 15 policy briefs.
