Researchers have developed an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume.

Artificial intelligence-based technique reveals previously unknown cell components that may provide new clues to human development and disease.

Researchers have developed a technique for assembling optoelectrodes that looks to offer the best of silicon-based electrodes and polymer-based electrodes. The scientists demonstrated it is possible to efficiently create a semiflexible light-emitting electrode by removing the stiff silicon material from underneath the tip of the probe. The resulting device can study deep brain tissues with high resolution to record signals from individual nerve cells and stimulate small groups of neurons with state-of-the-art techniques such as optical waveguides.

How can we better diagnose blood diseases? A research group aims to answer this question with artificial intelligence (AI). Their goal is to facilitate the time-consuming analysis of bone marrow cells under the microscope. The researchers developed the largest open-source database on microscopic images of bone marrow cells to date. They use it as the basis for an AI model with high potential for routine diagnostics.

Poor sleep in the over 50s is linked to more negative perceptions of aging, which in turn can impact physical, mental and cognitive health, new research has revealed. A study found that people who rated their sleep the worst also felt older, and perceived their own physical and mental aging more negatively.

Investigators used the power of nanotechnology to discover a new way that cancer can disarm its would-be cellular attackers by extending out nanoscale tentacles that can reach into an immune cell and pull out its powerpack.
