Two prototypes for a NASA mission concept called SWIM (short for Sensing With Independent Micro-swimmers) are arranged beside a much smaller nonfunctioning model representing the final envisioned size of the robot: about 5 inches (12 centimeters) long. The plastic prototypes were built at NASA’s Jet Propulsion Laboratory in Southern California to demonstrate the feasibility of the concept, a swarm of dozens of self-propelled, cellphone-size robots exploring the waters of icy moons like Jupiter’s Europa and Saturn’s Enceladus. Delivered to the subsurface ocean by an ice-melting cryobot, the tiny robots would zoom away to look for chemical and temperature signals that could point to life. The prototypes were used in more that 20 rounds of underwater testing in a pair of tanks at JPL and in a competition swimming pool at Caltech in Pasadena. Relying on low-cost, commercially made motors and electronics, the robots are pushed along by two propellers and use two to four flaps for steering. The prototype in the center of the image weighs 3.7 pounds (1.7 kilograms) and is 14.5 inches (37 centimeters) long, 6 inches (15 centimeters) wide, and 2.5 inches (6.5 centimeters) tall, with a volume of 104 cubic inches (1.7 liters). The upgraded prototype at left is slightly bigger: 16.5 inches (42 centimeters) long, 3 inches (7.5 centimeters) tall, with a weight of 5 pounds (2.3 kilograms) and a volume of 140 cubic inches (2.3 liters). In pool tests, the prototype at left demonstrated controlled maneuvering, the ability to stay on and correct its course, and a back-and-forth “lawnmower” exploration pattern. It managed all of this autonomously, without the team’s direct intervention. The robot even spelled out “J-P-L.” As conceived for spaceflight and represented by the model at right, the robots would have dimensions about three times smaller than these prototypes – tiny compared to existing remotely operated and autonomous underwater scientific vehicles. The swimmers would feature miniaturized, purpose-built parts and employ a novel wireless underwater acoustic communication system for transmitting data and triangulating their positions. Several years more of work would be needed to make such an advanced concept ready for spaceflight. Led by JPL, SWIM development took place from spring 2021 to fall 2024. The project was supported by Phase I and II funding from NASA’s Innovative Advanced Concepts program under the agency’s Space Technology Mission Directorate. JPL is managed for NASA by Caltech in Pasadena, California. Astrobiology, droid,Touchless trash cans are one of the latest innovations in automated kitchen technology. They use infrared motion sensors to automatically lift the lid, allowing users to dispose of trash without touching the can. This hands-free operation makes them not only efficient and easy to use but also improves kitchen hygiene as it helps reduce contact with germs, bacteria and parasites that are often found in household waste. Choosing the ideal touchless trash can for your home will depend on several factors, from the number of people in your household to the shape, size and material that best suits your decor. As with regular trash cans, there are many different shapes and styles available. The most common shapes are round, oval, square or rectangular. While shape can play a factor in determining which trash can to get, it is more important to find the right size trash can for your space. A 13-gallon trash can is standard for a kitchen. However, a smaller 5- to 10-gallon option would be better if you want to place it in a cabinet. For large families that generate a lot of waste, a larger 20 to 30-gallon trash can may be preferable. The most common materials are either metal or plastic. While plastic is certainly the cheaper option, metal trash cans are more durable. A stainless steel trash can is a good option, as it will match kitchen appliances and won’t rust or tarnish with time. However, metal trash cans are more pricey, retailing between $100 and $200, depending on their size and features. There are only two choices when it comes to a power source: battery or mains. A mains-powered trash can requires a permanent power source, restricting its location options. Battery-powered trash cans can be placed wherever you like and are particularly suitable for bathrooms. Look for a model that gives a warning when the batteries need replacing to avoid any inconvenience. The features of a trash can significantly impact the price, so it is important to decide which features you would like. Some trash cans have carbon filters that absorb unpleasant odors; however, remember that the filters must be replaced periodically. Other trash cans may feature a locking mechanism, which is handy if you have pets or small children because the lid will remain closed even if it’s knocked over. simplehuman 45 Liter / 12 Gallon Semi-Round Automatic Sensor Trash Can What you need to know: An elegant-looking option available in a range of metallic and colored finishes.

NoneVikings staying on track and in control behind Sam Darnold’s composure and confidence
RBI governor Sanjay Malhotra Sanjay Malhotra , who took over as RBI's 26th governor on Wednesday, said stability, trust and growth will remain the central bank's core values. "India's growth trajectory must continue, and RBI will play a key role in fostering it. Financial inclusion is central to this effort," he said in Mumbai. The ex-revenue secretary said while ensuring stability - "a core value in taxation, fiscal and monetary policy as we navigate a dynamic world" - it was necessary to remain agile and responsive to changing circumstances. He added RBI would undertake a consultative approach, "recognising that knowledge and expertise are not monopolised by any single institution". Many experts view him as more dovish compared to predecessor Shaktikanta Das , who maintained rates despite growth decelerating to 5.4% in Q2 of FY25. Continuity, policy stability to remain core values: RBI governor MUMBAI: Continuity, stability, trust and growth will remain RBI's core values, its new governor said on Wednesday. Sanjay Malhotra said that the country's growth trajectory must continue and that RBI will play a key role in fostering it. Malhotra, a career bureaucrat, assumed office as RBI's 26th governor on Wednesday. He replaces Shaktikanta Das, whose six-year term ended on Tuesday. "India's growth trajectory must continue, and RBI will play a key role in fostering this growth. Financial inclusion is central to this effort. While significant progress has been made in bringing banking services to every corner of the country, more remains to be done," Malhotra said in his first press conference as governor. "I will continue to uphold the legacy and take it forward," he said, adding that RBI had, in its 90th year, given itself the theme of stability, trust, and growth - three apt pillars which are very pertinent as the economy was entering the "Amrit Kaal" and to realise the vision of "Viksit Bharat" by 2047. "It's a huge responsibility we have, to ensure that the growth the country needs continues and that will continue," he said. Malhotra did not share his thoughts on the macroeconomic situation or other major issues, saying he would like to understand and discuss matters before giving his views. Many, however, see him as more dovish compared to predecessor Shaktikanta Das, who maintained rates despite growth decelerating to 5.4% in Q2 FY25. "Policy stability is crucial. Whether in taxation, fiscal, or monetary policy, continuity and stability give businesses and individuals confidence. This will remain a core value as we navigate a dynamic world characterised by geopolitical tensions, climate change, and political uncertainties," he said. He also noted that while ensuring stability, it was necessary to remain agile and responsive to changing circumstances. Malhotra, who was the revenue secretary, said RBI would undertake a consultative approach. "This approach ensures that policies are well-informed and effective. I intend to continue the practice, recognising that knowledge and expertise are not monopolised by any single institution," he said. Ready to Master Stock Valuation?
