New Datacenter In Italy Captures Heat Waste

Slashdot.org - Thu, 06/26/2025 - 05:00
Italian utility A2A and French tech firm Qarnot have launched a data center in Brescia, Italy, that captures waste heat from servers and redirects it to a local district heating system. "The Brescia project is expected to meet the heating needs of more than 1,350 apartments and cut carbon dioxide emissions by 3,500 tons annually -- equivalent to the absorption capacity of over 22,000 trees," reports Reuters. From the report: "The rapid spread of data centers and the growing electrification of consumption require major investments in power grids. But data centers also offer a remarkable opportunity for cities with district heating networks," A2A CEO Renato Mazzoncini said at the inauguration. "In (the Italian region of) Lombardy alone, with projects already in the pipeline, we estimate that 150,000 apartments could be heated this way," Mazzoncini added.

James Webb Space Telescope Discovers Its First Exoplanet

Slashdot.org - Thu, 06/26/2025 - 02:00
The James Webb Space Telescope has discovered its first new exoplanet, TWA 7b -- a young, low-mass planet about 100 times the mass of Earth, making it the lightest planet ever directly imaged beyond the solar system. Space.com reports: TWA 7b was discovered in the debris rings that surround the low-mass star CE Antilae, also known as TWA 7, located around 111 light-years from Earth. CE Antilae is a very young star, estimated to be around just a few million years old. If that seems ancient, consider the sun, a "middle-aged" star, is around 4.6 billion years old. [...] The disk of CE Antilae is divided into three distinct rings, one of which is narrow and bounded by two empty "lanes" mostly devoid of matter. When imaging this ring, the JWST spotted an infrared-emitting source, which the team of astronomers determined is most likely a young exoplanet. They then used simulations that confirmed the formation of a thin ring and a "hole" exactly where this planet is positioned, corresponding to JWST observations. The research has been published in the journal Nature.

Swarms of Tiny Nose Robots Could Clear Infected Sinuses, Researchers Say

Slashdot.org - Wed, 06/25/2025 - 22:30
An anonymous reader quotes a report from The Guardian: Swarms of tiny robots, each no larger than a speck of dust, could be deployed to cure stubborn infected sinuses before being blown out through the nose into a tissue, researchers have claimed. The micro-robots are a fraction of the width of a human hair and have been inserted successfully into animal sinuses in pre-clinical trials by researchers at universities in China and Hong Kong. Swarms are injected into the sinus cavity via a duct threaded through the nostril and guided to their target by electromagnetism, where they can be made to heat up and catalyze chemical reactions to wipe out bacterial infections. There are hopes the precisely targeted technology could eventually reduce reliance on antibiotics and other generalized medicines. [...] The latest breakthrough, based on animal rather than human trials, involves magnetic particles "doped" with copper atoms which clinicians insert with a catheter before guiding to their target under a magnetic field. The swarms can be heated up by reacting to light from an optical fibre that is also inserted into the body as part of the therapy. This allows the micro-robots to loosen up and penetrate viscous pus that forms a barrier to the infection site. The light source also prompts the micro-robots to disrupt bacterial cell walls and release reactive oxygen species that kill the bacteria. The study, published in Nature Robotics, showed the robots were capable of eradicating bacteria from pig sinuses and could clear infections in live rabbits with "no obvious tissue damage." The researchers have produced a model of how the technology could work on a human being, with the robot swarms being deployed in operating theatre conditions, allowing doctors to see their progress by using X-rays. Future applications could include tackling bacterial infections of the respiratory tract, stomach, intestine, bladder and urethra, they suggested. "Our proposed micro-robotic therapeutic platform offers the advantages of non-invasiveness, minimal resistance, and drug-free intervention," they said.
