Walker was hit once in the abdomen and died at a hospital about an hour later.Save faces life imprisonment if convicted of murder, shooting into an inhabited dwelling, assault with a semi-automatic firearm and being a felon in possession of a firearm. He pleaded not guilty.Deputy District Attorney Kristie Nikoletich said the shooting stemmed from a verbal argument and physical fight between Save and his older brother. Following the argument, Save retrieved a gun and fired at his sibling “to show his brother he wasn’t scared of him,” the prosecutor alleged.Save then allegedly hid the 9mm firearm, which he was not allowed to possess due to a previous hit-and-run conviction involving the death of an elderly woman, Nikoletich said. Save was sentenced to probation in that case,she said.Nikoletich said Save was charged with murder due to “the defendant’s conscious disregard for human life.”Save, who’s being held in lieu of $3 million bail, is due back in court Aug. 29 for a readiness conference.

Spotify and most other streaming services rely on compressed audio, which robs the listener of full fidelity. Enter Tidal, the only “major” service that delivers lossless audio — meaning at least on par with CD quality, if not better. Want to see (er, hear) the difference for yourself? Grab this excellent extended trial while you can. It’s just $6 for three months, and it’s good for up to six listeners. Sarah Tew/CNET Turo is kind of like Uber meets Airbnb: You borrow someone’s car, but you do all the driving. I’ve used it many times and found it a great alternative to traditional car-rental services — in part because you get to choose exactly the vehicle you want (not just, say, “midsize”) and in part because you can often do pickup and dropoff right outside baggage claim.Between now and Sept. 1, the first 300 people to check out can get $30 off any Turo rental with promo code LDW30. See It Sprint Turo: Save $30 on any car rental I thought this might be a mistake, but, no, the weirdly named HP Laptop 15t Value is indeed quite the value at this price. Specs include an Intel Core i7 processor, 12GB of RAM, a 256GB solid-state drive and a 15.6-inch display. However, I strongly recommend paying an extra $50 to upgrade that display to FHD (1,920×1,080), because you’re not likely to be happy with the native 1,366×768 resolution. Angela Lang/CNET Uber,I’m shocked — shocked! — to learn that stores are turning Labor Day into an excuse to sell stuff. Wait — no, I’m not. As much as I respect the original intent of the holiday (which became official back in 1894), to most of us, it’s just a bonus day off — one that’s blissfully tacked onto a weekend. So, yeah, stores; go ahead, run your sales. I’m listening. Perhaps unsurprisingly, Labor Day doesn’t bring out bargains to compete with the likes of Black Friday (which will be here before you know it), but there are definitely some sales worth your time.For example:We’ve rounded up the best Labor Day mattress deals.We’ve also gathered the best Labor Day laptop deals at Best Buy.The 2019 Vizio P Series Quantum is back under $999.Be sure to check out Amazon’s roughly three dozen Labor Day deals on TVs and audio. Google Express is having a big sale as well, one that includes deals on game consoles, AirPods, iPhones, laptops and more.Below I’ve rounded up a handful of individual items I consider to be the cream of the crop, followed by a handy reference guide to other Labor Day sales. Keep in mind, of course, that products may sell out at any time, even if the sale itself is still running. Note that CNET may get a share of revenue from the sale of the products featured on this page. 0 Recently updated to include digital-photo-frame capabilities, the Lenovo Smart Clock brings Google Assistant goodness to your nightstand. It’s a little smaller than the Amazon Echo Show 5, but also a full $30 less (and tied with Prime Day pricing) during this Best Buy Labor Day sale. Read DJI Osmo Action preview Review • iPhone XS review, updated: A few luxury upgrades over the XR An Echo Dot makes a fine match for any Fire edition TV, because you can use the latter to say things like, “Alexa, turn on the TV.” Right now, the 24-inch Insignia Fire TV Edition starts at just $100, while the 32-inch Toshiba Fire TV Editions is on sale for $130. Just add any Fire TV Edition to your cart, then add a third-gen Echo Dot, and presto: The latter is free. The problem with most entry-level laptops: They come with mechanical hard drives. That makes for a mighty slow Windows experience. This Lenovo model features a 128GB solid-state drive, so it should be pretty quick to boot and load software, even with its basic processor. Plus, it has a DVD-burner! That’s not something you see in many modern laptops, especially at this price.

Hemant Mishra/Mint via Getty Images Uber on Friday set a price range of $44 to $50 a share for its initial public offering, according to an updated filing with the US Securities and Exchange Commission. The ride-hailing company plans to offer 180 million shares and seeks to raise about $9 billion in its IPO.The San Francisco-based company will list on the New York Stock Exchange using the ticker symbol UBER. Its IPO could come as soon as early May.On Friday, payment service PayPal also said it’ll invest $500 million into Uber as it extends a partnership the companies have maintained since 2013.In its IPO filing, Uber said it has operations in more than 700 cities in 63 countries on six continents. More than 91 million people use one of its services, which includes food delivery, at least once a month, the company said. Its drivers reportedly complete 14 million trips every day. If all goes as planned, 2019 will be a big year for tech IPOs. Airbnb, Pinterest and Slack are also expected to go public. Uber arch-rival Lyft issued its IPO in March with a strong stock market debut, but has faltered some since then. Lyft shares were trading around $56 on Friday, well below their $72 IPO price.

(Left) Illustration of the new Li-I solar flow battery with an aqueous electrolyte, which compared to organic solvents has advantages in terms of performance, cost, and environmental friendliness. (Right) When the solar battery is exposed to light, the voltage that it needs from an external source immediately decreases, as the device is being charged by the solar cell. Credit: Yu, et al. ©2015 American Chemical Society Semiliquid battery competitive with both Li-ion batteries and supercapacitors (Phys.org)—Last October, researchers at Ohio State demonstrated the world’s first solar battery—a solar cell and a lithium-oxygen (Li-O2) battery combined into a single device. The main attraction of the solar battery concept is that, because it can harvest, convert, and store solar energy as chemical energy all in one device, it eliminates losses that occur when transferring electrons between multiple devices. The researchers estimate that this integration can potentially reduce overall costs by about 25%. © 2015 Phys.org Journal information: Journal of the American Chemical Society The researchers explain that the key component of the solar battery design is the electrolyte because it bridges the hydrophilic aqueous Li-I battery and the hydrophobic surface of the dye-sensitized solar cell photoelectrode. The electrolyte consists of several ingredients, including lithium iodide salt (LiI), which is essential for the battery’s electrochemical reactions, along with various additives that allow the hydrophilic electrolyte to wet the hydrophobic photoelectrode surface. This surface-wetting contact between the two components is essential for efficiently transferring charge from the solar cell to the battery.Overall, tests showed that the Li-I solar battery has a theoretical capacity (35.7 Ah/L with 2M LiI) close to that of conventional Li-I batteries, and it can be photocharged to about 91% of its theoretical capacity. It also appears to have good cyclability, retaining its full capacity for at least 25 cycles. Unfortunately, it currently takes about 16.8 hours to photocharge the device with a 0.1-mL electrolyte to its full capacity, and this long charge time is one of the biggest areas in need of improvement. The researchers plan to address this problem by improving the efficiency of the aqueous-compatible photoelectrode, among other strategies.In the future, the scientists also plan to extend some of the concepts in this solar battery design to other combinations of battery chemistry and solar cell photoelectrochemistry. One possibility is developing solar batteries that use sodium instead of lithium as the anode, since sodium has been gaining appeal due to its wide abundance and inexpensive fabrication costs.”Improving the solar battery’s photocharging rate and achieving full photocharging are among our goals,” Wu said. “We hope this technology will ultimately be commercialized for applications in grid-scale stationary solar energy conversion and storage.” Explore further This document is subject to copyright.

Although the solar-charged Li-O2 battery represented a novel and promising concept, it had a drawback: its electrolyte was made of organic solvents, which are non-aqueous and therefore not compatible with aqueous (water-based) redox flow batteries, limiting the device’s performance. Organic solvents also face problems with environmental impact and cost.Now in a new paper published in the Journal of the American Chemical Society, Ohio State Professor Yiying Wu and his research group have improved upon their original design by developing a solar battery that replaces the organic solvents with a more environmentally friendly and cost-effective iodine redox-based aqueous solution. The new version is an aqueous lithium-iodine (Li-I) solar flow battery, which integrates an aqueous Li-I redox flow battery with a dye-sensitized solar cell. This compatibility allows the device to operate at a higher voltage, improving its overall performance and bringing the solar battery a step closer to commercialization.”I think the greatest significance is the identification and demonstration of aqueous flow batteries as the platform for solar batteries,” Wu told Phys.org. “Flow batteries are flexible in materials selection. They are modular and scalable, and are being considered for applications in stationary storage, stand-alone power and electric vehicles. Our aqueous flow solar battery is an important step that brings this simultaneous solar energy conversion and storage concept closer to practical applications.”When exposed to sunlight during the charging process, the Li-I solar battery receives about 20% of its charging energy from the sun, meaning it uses 20% less energy from conventional energy sources compared to conventional Li-I batteries. The photoassisted charging process occurs when sunlight illuminates the dye molecules, causing them to become photoexcited and inject their electrons into the photoelectrode—the battery’s third electrode, in addition to the conventional cathode and anode. The photoexcited electrons supply a photovoltage to the battery, which reduces the charging voltage (which is supplied by external energy sources) to a value that is even lower than the discharging voltage. As the researchers explain, this feat would be thermodynamically impossible without the solar energy input.

A new research shared by Digital Content Next, reveals idle Android devices send 10 times more data than iOS devices. In a paper titled “Google Data Collection,” by Douglas C. Schmidt, a computer science professor at Vanderbilt University. Schmidt in the research catalogues how much data Google is collecting about consumers and their most personal habits across all of its products and how that data is being tied together. More from Schmidt’s research findings: An idle Android phone with Chrome web browser active in the background communicated location information to Google 340 times during a 24-hour period. An equivalent experiment found that on an iOS device with Safari open but not Chrome, Google could not collect any appreciable data unless a user was interacting with the device. Additionally an idle Android phone with running Chrome sends back to Google nearly fifty times as many data requests per hour as an idle iPhone running Safari. Overall, an idle Android device was found to communicate with Google nearly 10 times more often than an Apple device communicates with Apple servers. Data transmission frequencies on an android device can potentially tie together data through passive means with the help of user’s personal information. For example, anonymous advertising identifiers collect activity data from apps and third-party web page visits of a user. Similarly Google can associate the cookie to a user’s Google account when a user accesses a Google app in the same browser that a third-party web page was accessed. Source: Digital Content Next The research also showed Google to track location data even after the consumer turned off their settings. Google had clarified about its location policies but yet it continues to track location data through app features. The location data is used for ad targeting purposes, Google’s primary business model. While Apple uses differential privacy to gather anonymous usage insights from devices like iPhones, iPads, and Macs. Apple says the data it collects off-device is used to improve services like Siri suggestions, and to help identify problematic websites that use excessive power or too much memory in Safari. When users sets up their iOS device, it will explicitly asks users if they wish to provide usage information on an opt-in basis. If a user declines, no data is collected by the device unless they choose to opt in at a later time. Apple CEO, Tim Cook and Apple executives’ belief that customers are not the company’s product seems to be clearly in action here. The company also has a dedicated privacy website that explains its approach to privacy and government data requests. Read Next: Do you want to know what the future holds for privacy?
