📰 $5,900 Unitree R1 robot is surprisingly affordable
Unitree has released the R1 humanoid robot at a surprisingly low price of $5,900, causing excitement in the tech world and making humanoid robots more accessible. The R1 showcases impressive coordination and agility in promo videos, thanks to its 26 joint degrees of freedom and advanced sensors. Despite its affordable price, the R1 offers capabilities similar to more expensive models, with an 8-core CPU and GPU for tasks like voice and image recognition. The robot’s compact size and one-hour battery life make it suitable for various settings, including classrooms and labs. Researchers and educators are eager to explore the possibilities of the R1 in academic projects and medical trials, potentially revolutionizing the use of humanoid robots in everyday environments.
📰 Google turns CO2 into battery power for clean energy
Google has partnered with Energy Dome to develop long-duration energy storage systems using carbon dioxide. This innovative approach aims to store excess energy from wind and solar sources for later use when production is low. Unlike traditional batteries that offer limited backup power, the CO2 Battery can provide clean energy for up to 24 hours. The technology works by compressing carbon dioxide gas into a liquid, which is then heated and expanded to generate electricity through a turbine. Energy Dome’s successful commercial facility in Italy demonstrates the effectiveness of this carbon-free energy storage solution. Google’s support for this technology could lead to a widespread adoption that enhances renewable energy reliability and reduces the need for fossil fuel power plants.
📰 New tattoo sticker detects date rape drugs in 1 second
Scientists in South Korea have developed a temporary tattoo sticker that can detect drink tampering by changing color when exposed to GHB, a common date rape drug. The sticker provides a quick and discreet way for individuals to check their drinks for safety in social settings. Made from a flexible material called PDMS, the sticker contains gels with a chemical called BHEI that reacts to GHB, triggering a color change from yellow to red within one second. The detection limit is highly sensitive, capable of detecting as little as 0.01 micrograms of GHB per milliliter. The red color change remains visible for up to 30 days after removal, potentially serving as evidence if needed. This innovative solution offers a simple and effective method to protect against drink spiking, with plans for future versions to detect other drugs like ketamine or Rohypnol.
📰 Tea app hacked as women’s photos, IDs & even DMs leaked online
Dating sites like Ashley Madison and the dating safety app Tea have experienced significant data breaches, compromising the personal information of their users. Tea, marketed as a safe space for women, suffered a breach involving unauthorized access to a legacy database containing images and private messages of users. The breach included approximately 72,000 images, 1.1 million direct messages, and highly sensitive conversations about topics like abortions and cheating. Tea disabled its messaging system in response to the breach and stated that no email addresses or phone numbers were exposed. Users affected by the breach are at risk of identity theft and harassment campaigns, highlighting the importance of taking steps to protect privacy and limit the fallout.
📰 Ultra-thin sound blocker cuts traffic noise dramatically
Researchers at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have developed an ultra-thin traffic noise absorber that significantly reduces sound levels, occupying just a fraction of the space required by traditional materials. The absorber, only 2.1 inches thick, can be customized to target specific types of noise, making it suitable for various indoor and outdoor settings. The material is a multi-layered mineral foam made from gypsum or cement, with pores of different sizes that help dissipate sound waves efficiently. In a real-world test in Zurich, the absorber reduced traffic noise by up to 4 decibels, making it effective in urban areas. The material is weather-resistant, fireproof, recyclable, and safe for indoor use, offering architects and developers more flexibility in noise protection. Despite manual production challenges, efforts are underway to automate production for broader commercial use, potentially revolutionizing noise control in construction projects.
