Bio-batteries constructed by electroactive microorganisms have unique advantages in physiological monitoring, tissue integration, and powering implantable devices due to their superior adaptability and biocompatibility. However, the development of miniaturized and portable bio-batteries that are plug and play and compatible with existing devices remains a challenge. /news/2025-04-portable-bio-battery-hydrogels-nerve.html Biotechnology Wed, 30 Apr 2025 17:18:03 EDT news665252282 Lately, there's been plenty of progress in 3D printing objects from the lunar regolith. We've reported on several projects that have attempted to do so, with varying degrees of success. However, most of them require some additive, such as a polymer or salt water, as a binding agent. Recently, a paper from Julien Garnier and their co-authors at the University of Toulouse, published in Acta Astronautica, attempted to make compression-hardened 3D-printed objects using nothing but the regolith itself. /news/2025-04-quality-3d-lunar-regolith-varies.html Planetary Sciences Mon, 28 Apr 2025 17:06:03 EDT news665078761 In the sweltering summer of AD18, a desperate chant echoed across China's sun-scorched plains: "Heaven has gone blind!"

Researchers from Drexel University, the University of Pennsylvania, and Accenture Labs in California have taken a new approach to the challenge by building a full textile energy grid that can be wirelessly charged. In their recent study, the team reported that it can power textile devices, including a warming element and environmental sensors that transmit data in real-time. /news/2024-10-clothesline-grid-mxene-nanomaterials-enable.html Nanomaterials Thu, 31 Oct 2024 14:30:04 EDT news649603802 When the International Astronomical Union announced in 2006 that Pluto was being demoted from its status as the sun's ninth planet, many astronomers and non-experts alike were shocked. /news/2024-09-pluto-mission-south-african-astronomers.html Planetary Sciences Mon, 09 Sep 2024 15:05:04 EDT news645113101 How much was known at the mid-20th century about the dangers of human-caused climate change?

However, the need for precise coordination between light delivery, stage movement, and resin properties makes scalable fabrication of such custom microscale particles challenging. Now, researchers at Stanford University have introduced a more efficient processing technique that can print up to 1 million highly detailed and customizable microscale particles a day. /news/2024-03-high-microscale-3d-technique.html Materials Science Wed, 13 Mar 2024 16:17:04 EDT news629565421 One of the fundamental goals of basic biology is understanding how diverse cell types work in concert to form tissues, organs, and organ systems. Recent efforts to catalog the different cell types in every tissue in our bodies are a step in the right direction, but only one piece of the puzzle.
