Cryo-em freezes the funk: How scientists visualized a pungent protein

Matter and energy from Science Daily Feed - Tue, 05/27/2025 - 10:52am
Most people have witnessed -- or rather smelled -- when a protein enzyme called sulfite reductase works its magic. This enzyme catalyzes the chemical reduction of sulfite to hydrogen sulfide. Hydrogen sulfide is the rotten egg smell that can occur when organic matter decays and is frequently associated with sewage treatment facilities and landfills. But scientists have not been able to capture a visual image of the enzyme's structure until now, thus limiting their full understanding of how it works.

Hitting the right notes to play music by ear

Computers and Math from Science Daily Feed - Tue, 05/27/2025 - 9:48am
A team analyzed a range of YouTube videos that focused on learning music by ear and identified four simple ways music learning technology can better aid prospective musicians -- helping people improve recall while listening, limiting playback to small chunks, identifying musical subsequences to memorize, and replaying notes indefinitely.

Home water-use app improves water conservation

Matter and energy from Science Daily Feed - Tue, 05/27/2025 - 9:46am
A new study has found that a smartphone app that tracks household water use and alerts users to leaks or excessive consumption offers a promising tool for helping California water agencies meet state-mandated conservation goals. The study found that use of the app -- called Dropcountr -- reduced average household water use by 6%, with even greater savings among the highest water users.

Machine learning simplifies industrial laser processes

Matter and energy from Science Daily Feed - Tue, 05/27/2025 - 9:46am
Laser-based metal processing enables the automated and precise production of complex components, whether for the automotive industry or for medicine. However, conventional methods require time- and resource-consuming preparations. Researchers are now using machine learning to make laser processes more precise, more cost-effective and more efficient.

A chip with natural blood vessels

Computers and Math from Science Daily Feed - Tue, 05/27/2025 - 9:44am
Miniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs blood vessels, and they are very hard to create. Now, new technology has been developed to create reproducible blood vessels using high-precision laser pulses. Tissue has been created that acts like natural tissue.

'Raindrops in the Sun's corona': New adaptive optics shows stunning details of our star's atmosphere

Space and time from Science Daily Feed - Tue, 05/27/2025 - 9:44am
Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur from images caused by the Earth's atmosphere. Their ground-breaking results pave the way for deeper insight into coronal heating, solar eruptions, and space weather, and open an opportunity for new discoveries in the Sun's atmosphere.

How brain stimulation alleviates symptoms of Parkinson's disease

Matter and energy from Science Daily Feed - Tue, 05/27/2025 - 9:44am
Persons with Parkinson's disease increasingly lose their mobility over time and are eventually unable to walk. Hope for these patients rests on deep brain stimulation, also known as a brain pacemaker. In a current study, researchers investigated whether and how stimulation of a certain region of the brain can have a positive impact on ambulatory ability and provide patients with higher quality of life. To do this, the researchers used a technique in which the nerve cells are activated and deactivated via light.

Emotional responses crucial to attitudes about self-driving cars

Computers and Math from Science Daily Feed - Tue, 05/27/2025 - 9:42am
When it comes to public attitudes toward using self-driving cars, understanding how the vehicles work is important -- but so are less obvious characteristics like feelings of excitement or pleasure and a belief in technology's social benefits.

New fuel cell could enable electric aviation

Matter and energy from Science Daily Feed - Tue, 05/27/2025 - 9:41am
Engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion batteries. Powered by a reaction between sodium metal and air, the device could be lightweight enough to enable the electrification of airplanes, trucks, or ships.

New Adaptive Optics Show "Raindrops" on the Sun

Universe Today Feed - Tue, 05/27/2025 - 8:47am

Modern ground-based telescopes rely on adaptive optics (AO) to deliver clear images. By correcting for atmospheric distortion, they give us exceptional pictures of planets, stars, and other celestial objects. Now, a team at the National Solar Observatory is using AO to examine the Sun's corona in unprecedented detail.
