| Researchers shrink camera to the size of a salt grain Posted: 29 Nov 2021 09:27 AM PST 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. |
| We might not know half of what’s in our cells, new AI technique reveals Posted: 24 Nov 2021 12:39 PM PST Artificial intelligence-based technique reveals previously unknown cell components that may provide new clues to human development and disease. |
| Optoelectrode changes reduce injuries to brain tissue, improve nerve research Posted: 23 Nov 2021 10:13 AM PST 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. |
| Fighting blood diseases with artificial intelligence Posted: 22 Nov 2021 10:55 AM PST 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 linked to feeling older and worse outlook on aging, which can impact health Posted: 22 Nov 2021 10:55 AM PST 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. |
| Cancer cells use ‘tiny tentacles’ to suppress the immune system Posted: 18 Nov 2021 05:36 PM PST 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. |
