Precision instrument bolsters efforts to find elusive dark energy

Matter and energy from Science Daily Feed - Wed, 06/26/2024 - 12:21pm
Dark energy -- a mysterious force pushing the universe apart at an ever-increasing rate -- was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle causing the expansion. Physicists combined an optical lattice with an atom interferometer to hold atoms in place for up to 70 seconds -- a record for an atom interferometer -- allowing them to more precisely test for deviations from the accepted theory of gravity that could be caused by dark energy particles such as chameleons or symmetrons. Though they detected no anomalies, they're improving the experiment to perform more sensitive tests of gravity, including whether gravity is quantized.

Microrobot-packed pill shows promise for treating inflammatory bowel disease in mice

Computers and Math from Science Daily Feed - Wed, 06/26/2024 - 12:21pm
Engineers have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice. It significantly reduced IBD symptoms and promoted the healing of damaged colon tissue without causing toxic side effects.

Mechanical computer relies on kirigami cubes, not electronics

Computers and Math from Science Daily Feed - Wed, 06/26/2024 - 12:21pm
Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components. The system also includes a reversible feature that allows users to control when data editing is permitted and when data should be locked in place.

Shocked quartz reveals evidence of historical cosmic airburst

Space and time from Science Daily Feed - Wed, 06/26/2024 - 12:20pm
Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth's warming trend and into an anomalous near-glacial period called the Younger Dryas.

Scientists discover high-risk form of endometrial cancer -- and how to test for it -- using AI

Computers and Math from Science Daily Feed - Wed, 06/26/2024 - 12:20pm
A discovery promises to improve care for patients with endometrial cancer, the most common gynecologic malignancy. Using artificial intelligence (AI) to spot patterns across thousands of cancer cell images, the researchers have pinpointed a distinct subset of endometrial cancer that puts patients at much greater risk of recurrence and death, but would otherwise go unrecognized by traditional pathology and molecular diagnostics. The findings will help doctors identify patients with high-risk disease who could benefit from more comprehensive treatment.

An optical lens that senses gas

Matter and energy from Science Daily Feed - Wed, 06/26/2024 - 12:20pm
A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled by the hybrid glass material from which it is made. The molecular structure of the lens consists of a three-dimensional lattice with cavities that can accommodate gas molecules, thereby affecting the optical properties of the material.
