The Delta variant of the coronavirus spread to more countries in recent weeks, and the total number of cases officially logged soared past half a million per day. The global number of deaths is now about two-thirds as high as it was at the peak of the previous wave, in April of this year. As the virus spreads, the potential rises for a vaccine-resistant strain to emerge. Meanwhile, in poorer countries, vaccines are scarce, and most populations are little protected (exhibit).

Search Engines is a software system that helps to carry out web searches. They search the World Wide Web in a systematic way for particular information specified by users, such as a list of web sites, news stories, a map, a directory listing or a biography of a celebrity. They are web search engines that search using a spider to systematically index the content of web sites. The term "search engine" can be used for the software system, the service that delivers web content, or both. In recent years, search engine optimization (SEO) has become a very popular way for web site owners to attract more traffic to their web sites.

Facebook Inc. executives have long said that artificial intelligence would address the company's chronic problems keeping what it deems hate speech and excessive violence as well as underage users off its platforms. That future is farther away than those executives suggest, according to internal documents reviewed by The Wall Street Journal. Facebook's AI can't consistently identify first-person shooting videos, racist rants and even, in one notable episode that puzzled internal researchers for weeks, the difference between cockfighting and car crashes.

It follows an approach where you read an explanation for a programming concept and then write the code character by character. One of the best Python books to start your Python Journey. This is a reliable companion to the Python documentation. It gives a rich view of the language and many of its most useful modules, whilst still being concise.

Teresa Carey: This is Scientific American's 60-Second Science. Every morning at five o'clock, composer Walter Werzowa would sit down at his computer to anticipate a particular daily e-mail. It came from six time zones away, where a team had been working all night (or day, rather) to draft Beethoven's unfinished 10th Symphony--almost two centuries after his death. The e-mail contained hundreds of variations, and Werzowa listened to them all. Carey: Werzowa was listening for the perfect tune--a sound that was unmistakably Beethoven.

The United States has offered unspecified condolence payments to the families of the 10 civilians, including seven children, who were mistakenly killed in the Aug. 29 drone strike in Kabul that took place shortly before American troops withdrew from Afghanistan. The Pentagon also said it's working with the State Department to support family members who may want to relocate to the United States. The U.S. military insisted for almost three weeks that the drone strike was justified, claiming it had stopped an attack planned for Kabul's airport. But it later changed its tune amid an overwhelming amount of evidence. Weeks after the Pentagon acknowledged the strike had hit civilians, Colin H. Kahl, the under secretary of defense for policy, held a virtual meeting with Steven Kwon, the founder and president of Nutrition & Education International.

In brief Authorities in the United Arab Emirates have requested the US Department of Justice's help in probing a case involving a bank manager who was swindled into transferring $35m to criminals by someone using a fake AI-generated voice. The employee received a call to move the company-owned funds by someone purporting to be a director from the business. He also previously saw emails that showed the company was planning to use the money for an acquisition, and had hired a lawyer to coordinate the process. When the sham director instructed him to transfer the money, he did so thinking it was a legitimate request. But it was all a scam, according to US court documents reported by Forbes.

Facebook Is Researching AI Systems That See, Hear, and Remember Everything You Do James Vincent The Verge "[Facebook's AI team] imagines AI systems that are constantly analyzing peoples' lives using first-person video; recording what they see, do, and hear in order to help them with everyday tasks. Facebook's researchers have outlined a series of skills it wants these systems to develop, including'episodic memory' (answering questions like'where did I leave my keys?') and'audio-visual diarization' (remembering who said what when)." Drone Delivers Lungs to Transplant Recipient, a Medical First George Dvorsky Gizmodo "As the Canadian Press reports, some 80% of donated lungs cannot be used owing to problems having to do with insufficient oxygenation or a failure to meet minimal functional standards. And like any transplanted organ, time is of the essence; the quicker an organ can be brought to the patient, the better. Hence the desire to ship organs through the air, rather than through congested city traffic."

PASS stands for Pictures without humAns for Self-Supervision. It is a large-scale unlabelled image dataset created to alleviate ethical, legal, and privacy concerns around the famous Imagenet dataset. Motivated by this, we thus consider forming a dataset without using labels, significantly increasing diversity and removing the search engine selection bias. Because we remove images with humans, we further significantly reduce the risk of including contextual biases linked to the appearance of people. Furthermore, due to its more random and unsupervised nature, this dataset also serves as a better benchmark for SSL to study scaling to natural images that are not curated to a pre-defined set of class labels, addressing a technical shortcoming of current evaluations.
