The First Gene-Edited Squid in History Is a Biological Breakthrough

Slashdot.org - Wed, 08/12/2020 - 15:07
Squid are among the smartest ocean dwellers. Along with other ink-squirting cephalopods like octopuses and cuttlefish, squid boast the largest brains of all invertebrates. They also have an incredibly complex nervous system capable of instantaneously camouflaging their bodies and communicating with each other using various signals. From a report: Scientists have long marveled at these sophisticated behaviors and have tried to understand why these tentacled creatures are so intelligent. Gene editing may be able to help researchers unravel the mysteries of the cephalopod brain. But until now, it's been too hard to do -- in part because cephalopod embryos are protected by a hard outer layer that makes manipulating them difficult. Recently, a group of marine scientists managed to engineer the first genetically altered squid using the DNA editing tool CRISPR. In addition to being a big milestone in biology, the advance has potential implications for human health: Because of their big brains, cephalopods are used to study neurodegenerative diseases like Alzheimer's and Parkinson's. The ability to edit the genes of these animals could help scientists study the genes involved in learning and memory as well as specific cephalopod behaviors. "I think you're going to see a huge jump in the use of these [gene-edited] organisms by neurobiologists," Joshua Rosenthal, PhD, a senior scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts, and a key architect of the first genetically engineered squid, tells OneZero. Rosenthal and his colleagues used CRISPR to snip out a gene responsible for the coloring of the squid's skin. As a result, the edited squid were transparent instead of having their usual reddish spots. The results were published July 30 in the journal Current Biology. But why bother to create a colorless squid? Rosenthal says the pigmentation gene was a logical starting place for experimentation. "If you see the pigmentation go away, it's easy to see if the gene editing is working," he explains. Being able to tinker with cephalopod DNA will allow scientists to better study what their individual genes do at a very basic level. The accomplishment wasn't easy. Scientists have successfully made gene-edited mice, monkeys, and other research animals to help them study a range of behaviors and medical conditions. But until now, they hadn't been successful at manipulating the genes of cephalopods.

Google Makes Building Android Apps on Chrome OS Easier

Slashdot.org - Wed, 08/12/2020 - 14:03
Google today launched ChromeOS.dev, a new site that aims to help developers get started with building Android apps for the company's Linux-based operating system. With today's update, Google is also making it easier to build and test Android applications on Chromebooks. From a report: The new ChromeOS.dev site, which is available in English and Spanish for now, is meant to "help developers maximize their capabilities on the platform through technical resources/tutorials, product announcements, code samples and more," a Google spokesperson told us. As Google notes in today's announcement, in the last quarter, Chromebook unit sales were up 127% year-over-year in the last quarter, compared to 40% for notebook sales in general. To help Android developers do all of their work on a Chromebook if they so desire, Google now offers the full Android Emulator on Chrome OS to test apps right on their Chromebooks. The team also made deploying apps on Chrome OS (M81 and newer) much easier. Developers can now deploy and test apps directly without having to use developer mode or connect devices via USB.

Scientists Turn Normal Red Bricks into Electricity-Storing Supercapacitors

Slashdot.org - Wed, 08/12/2020 - 13:08
Bricks are about as basic as architectural materials can get, yet these simple building blocks have hidden powers that can be leveraged to provide electricity, according to a new study. From a report: Scientists modified a common red brick -- the same kind you'll find on sale for under a dollar at your local hardware store -- so that it could power a green LED light. This proof-of-concept for a "smart brick" reveals that brick technology, which dates back thousands of years, can be tweaked to have futuristic applications, including electrical conductivity and sensing capabilities. The results were published on Tuesday in Nature Communications. "We have created a new brick that can be incorporated into your house that has the functionality of storing electrical energy," said study co-author Julio D'Arcy, assistant professor of chemistry at Washington University in St. Louis, in a call. "We are thinking that sensing applications is a low-hanging fruit for these bricks," he added.

Dropbox Launches Password Manager, Computer Backup, and Secure 'Vaults' Out of Beta

Slashdot.org - Wed, 08/12/2020 - 12:00
Dropbox is officially launching a handful of new consumer features out of beta today, along with some new tools for businesses. From a report: The cloud storage giant first introduced its password manager -- replete with a standalone mobile app for Android and iOS -- back in June. Similar to other password management apps on the market, Dropbox Passwords stores and encrypts users' online passwords and syncs them across all devices (desktop and mobile) so users don't have to remember multiple login credentials. Dropbox Passwords can also suggest strong, randomly generated, individual passwords for your online services, such as Facebook, Twitter, Netflix, and Dropbox itself. Dropbox Passwords is the result of last year's acquisition of Massachusetts-based Valt, which swiftly shuttered its own apps ahead of integration with Dropbox. Dropbox Passwords is available to everyone on a Dropbox Plus or Professional subscription from today. The San Francisco-based company is also launching its previously announced computer backup feature in general availability today. The tool, which is available for Dropbox Basic, Plus, and Professional users, automatically creates a cloud-based backup of any folder stored on a PC or Mac and is continuously synced.

Uber CEO Says Its Service Will Probably Shut Down Temporarily in California if It's Forced To Classify Drivers as Employees

Slashdot.org - Wed, 08/12/2020 - 11:03
Uber would likely shut down temporarily for several months if a court does not overturn a recent ruling requiring it to classify its drivers as full-time employees, CEO Dara Khosrowshahi said in an interview. From a report: "If the court doesn't reconsider, then in California, it's hard to believe we'll be able to switch our model to full-time employment quickly," Khosrowshahi said. Uber and rival Lyft both have about a week left to appeal a preliminary injunction granted by a California judge on Monday that will prohibit the companies from continuing to classify their drivers as independent workers. Following the order will require Uber and Lyft to provide benefits and unemployment insurance for workers. California's attorney general and three city attorneys brought the lawsuit against the companies under the state's new law, Assembly Bill 5, that aims to provide benefits to gig workers core to a company's business by classifying them as employees. In his decision granting the preliminary injunction, the judge rejected the notion that drivers should be considered outside the course of the companies' businesses, calling the logic "a classic example of circular reasoning."

Microsoft Surface Duo Phone Goes on Sale Starting at $1,399

Slashdot.org - Wed, 08/12/2020 - 10:00
Microsoft begins taking orders for its dual-screen Surface device in the U.S. on Wednesday, an attempt to re-enter the mobile handset market with a product that blends the features of a tablet with those of a phone. From a report: The Android-powered Surface Duo starts at $1,399 and will be available Sept. 10, said Microsoft Chief Product Officer Panos Panay. The device will be sold on Microsoft.com as well as by AT&T and Best Buy. It is the thinnest Surface ever, with screens that unfold completely to serve as a phone or act like a book to provide more space for different apps. The gadget represents Microsoft's return to the handset market following an ignominious retreat in 2016 after the company's acquisition of Nokia's handset unit crashed and burned in a costly writedown. It's also the company's first Surface device running Google's Android operating system, which Windows Phone once sought to vanquish. Why Android? Panay told reporters it came down to the need for apps -- Microsoft's previous efforts were largely doomed because of the lack of mobile developer support.
