A small international team of nanotechnologists, engineers and physicists has developed a way to force laser light into becoming a supersolid. Their paper is published in the journal Nature. The editors at Nature have published a Research Briefing in the same issue summarizing the work.

Supersolids are entities that exist only in the quantum world, and, up until now, they have all been made using atoms. Prior research has shown that they have zero viscosity and are formed in crystal-like structures similar to the way atoms are arranged in salt crystals.

Because of their nature, supersolids have been created in extremely cold environments where the quantum effects can be seen...

New method to detect life makes Mars sample return protocols rock solid

Within the next decade, space agencies plan to bring samples of rock from Mars to Earth for study. Of concern is the possibility these samples contain life, which could have unforeseen consequences. Therefore, researchers in this field strive to create methods to detect life...

Scientists have uncovered the mechanism behind how aspirin could reduce the metastasis of some cancers by stimulating the immune system, in a new study primarily funded by the Medical Research Council.

In the study, published in Nature, the scientists say that discovering the mechanism will support ongoing clinical trials, and could lead to the targeted use of aspirin to prevent the spread of susceptible types of cancer, and to the development of more effective drugs to prevent cancer metastasis.

The scientists caution that, in some people, aspirin can have serious side-effects and clinical trials are underway to determine how to use it safely and effectively to prevent cancer spread, so people should consult their doctor before starting to take it.

Johns Hopkins University engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging or mishandling whatever it holds.

The system’s hybrid design is a first for robotic hands, which have typically been too rigid or too soft to replicate a human’s touch when handling objects of varying textures and materials. The innovation offers a promising solution for people with hand loss and could improve how robotic arms interact with their environment.
