Fighter jets belonging to a Saudi-led coalition battling Yemen's Houthi rebels have launched dozens of air raids on several Yemeni provinces, as the kingdom announced the start of a new military operation. The Houthi-run Al Masirah Media Network reported air raids on the capital, Sanaa, as well as Marib, al-Jouf, al-Bayda, Hajjah and Saada provinces throughout Wednesday and into the night. It said an elderly woman and a child were killed and four others wounded in Saada province. In Sanaa, residents described the air raids, which also struck the city's international airport, as "violent". Saudi state television reported earlier on Wednesday that the coalition had begun a military push against the Houthis after the group stepped up cross-border missile and drone attacks on the kingdom.

The Chinese new car market has been topsy turvy lately, primarily because the government keeps playing around with its NEV (new energy vehicle) incentive program. China really, really wants people to buy electric cars -- either plug-in hybrids or battery electrics -- but found its original incentive program was costing too much money. So it modified the program, several times in fact, which caused confusion among car companies and customers. In general, people who are confused postpone buying decisions until things get clearer, and that's exactly what Chinese new car shoppers did. The second factor, of course, was production shutdowns caused by the coronavirus pandemic.

"AI and ML enhance the adoption of IoT by adding the Return on Investment (RoI) layer on top of the IoT stack for both businesses and consumers."- Utility and convenience have been one of the primary forces behind increased adoption of IoT in the Appliances and Consumer Electronics (ACE) sector in India. With Smart IoT powered appliances, end users can control and monitor appliances, set schedules, and automation rules using mobile apps and voice commands from voice assistants such as Google Home, Alexa, and Siri. Acknowledging this market trend, almost all major brands are adding IoT enabled appliances to their catalogue. From smart lighting to smart air conditioners and smart water purifiers, the Indian market has started witnessing the adoption of IoT products.

IIT Hyderabad Researchers are using computational methods to understand the factors and impediments in incorporating biofuels into the fuel sector in India. This work has been spurred by the increasing need to replace fossil fuels by bio-derived fuels, which, in turn, is driven by the dwindling fossil fuel reserves all over the world, and pollution issues associated with the use of fossil fuels. The model developed by the IIT Hyderabad team has shown that in the area of bioethanol integration into mainstream fuel use, the production cost is the highest (43 per cent) followed by import (25 per cent), transport (17 per cent), infrastructure (15 per cent) and inventory (0.43 per cent) costs. The model has also shown that feed availability to the tune of at least 40 per cent of the capacity is needed to meet the projected demands. A unique feature of this work is that the framework considers revenue generation not only as an outcome of sales of the biofuel but also in terms of carbon credits via greenhouse gas emission savings throughout the project lifecycle.

Twice a year, the world's fastest supercomputers take a test to see which is top of class. These hundred-million-dollar machines usually run on hundreds of thousands of processors, occupy warehouse floors, gobble up copious amounts of energy, and crunch numbers at an ungodly pace. All that computing is directed at some of humanity's toughest challenges with the likes of advanced climate modeling or protein simulations to help cure diseases. For the last two years, the US's Summit was the fastest supercomputer on the planet. But this week, a new system took the crown.

The concept is pretty genius. Take a beefy smart lock and a video doorbell and mash them both into a single unit. It's one-stop security shopping for the exterior of your smart home, letting you not only see who comes and goes, but giving you the power to open the door for them, too. While products like Amazon Key let you cobble together a solution like this from a collection of disparate products, the Lockly Vision marks the first time it's been integrated into a single device. Camera aside, Lockly Vision is functionally similar in design to Lockly's other deadbolts, such as the Lockly Secure Pro, giving you myriad ways to open the lock.

All of us use heating and cooling systems in our homes and offices on a day to day basis without knowing the impact. They account for almost half the average residential energy use and demand a lot of energy usage as well. Nest has come up with a smart thermostat known as Nest's Learning Thermostat. By using this, we'll be able to save money and the planet too. Smart thermostats basically are able to automatically adjust your indoor temperature settings based on the data of external humidity.

Earlier this month an article in the Financial Times by John Thornhill, the paper's innovation editor, caught my attention. Thornhill was relaying an intriguing set of ideas expressed by the authors of a new book, What To Do When Machines Do Everything? Before discussing the future impact of today's unfolding industrial innovations such as driverless cars, robotic surgery, precision agriculture, or automated beer service (as in the photo above), the three authors – Malcolm Frank, Paul Roehrig, and Ben Pring – make their first key point, citing the example of an early 19th century innovation that enabled an entire industry that generates $620bn. in annual revenues today. What could this invention have been – The steam engine? Theoretically, you might expect not be too far off with any one of these answers, but in fact the invention in question was … the lawnmower.

Headquartered in Quebec, Canada, Sinopé Technologies might be less familiar than some other smart-home brands, but we've reviewed several of the company's products and found a lot to like. Today, we'll take a look at its new Zigbee smart dimmer switch (model DM2500ZB), and its new smart home hub, the GT130 gateway. These two products are part of a new family of Zigbee 3.0-based products that Sinopé launched this spring, a collection that also includes a smart in-wall outlet, a smart switch, and updated smart thermostats. With its embrace of the Zigbee smart home protocol, Sinopé is relegating its proprietary smart home family--the Mi-Wi series, which included the GT125 gateway--to "legacy" status. Now when you buy a DIY Sinopé smart home product, you can control it with the company's own GT130 gateway or with any other Zigbee-based smart home hub, including Samsung SmartThings or any of the Amazon Echo smart speakers and displays that are equipped with Zigbee radios.

GL Robotics, an advanced technology business, is offering robotic lawnmowers for sale. Obviously, the lawnmower operates on its own and can operate from three to seven hours a day in the yard, so your grass will stay looking sharp at all times. And if you're wondering, the lawnmower is very quiet you can have the lawnmower programmed to run at night while you're at work or sleeping. Owner Laurie Summerlin says not only is it a timesaver but it has other perks as well. "It's very good for the environment it doesn't need gas or oil its a rechargeable battery, so you don't have the carbon footprint and the emission. A lawnmower actually uses as much carbon footprint as 11 cars for the same amount of time, so its good for the environment in that way. Its also very good for the grass it cuts a small amount for each day and it doesn't stress the grass," Summerlin said.
