Researchers from the University of Roehampton in London and the University of Sydney found that kangaroos know how to communicate with humans if they need help.According to the study published in the journal Biology Letters on Wednesday, out of the 11 kangaroos researched, 10 of them gazed at researchers when they were unable to access food during an unsolvable task. Out of those 10, nine of the marsupials would alternate their gaze from the object to the human.In some cases, researchers said, the kangaroos would sometimes even nudge or scratched them to ask for help, said co-author Alexandra Green, according to the University of Sydney.Before the study, researchers thought that only domesticated animals, like dogs, cats, wolves, horses, and sometimes goats, were capable of communicating with humans with an enhanced form of communication.Officials said the study's kangaroos were from various zoos in Australia and are familiar with people but are not considered domesticated. 996

Question-and-answer website Quora warned late Monday that hackers gained access to the personal data of as many as 100 million of its users.Quora discovered on Friday that one of its systems had been hacked by "a malicious third party," CEO Adam D'Angelo said in a blog post.The compromised information includes users' names, email addresses and encrypted passwords as well as data from social networks like Facebook (FB) and Twitter (TWTR) if people chose to link them to their Quora accounts.The hackers also obtained details about users' activity on Quora, such as questions, answers, upvotes and downvotes. But anonymously written questions and answers were not affected by the breach."The overwhelming majority of the content accessed was already public on Quora, but the compromise of account and other private information is serious," D'Angelo said.The site is now notifying affected users and logging them out."We believe we've identified the root cause and taken steps to address the issue, although our investigation is ongoing and we'll continue to make security improvements," D'Angelo said.Quora bills itself as "a place where you can ask questions you care about and get answers that are amazing."People can post a question to the platform like "What are some amazing facts about Apple, the company?" or "What is the ultimate sandwich?" — and see what answers other users come up with.The site's data breach is the latest in a series of high-profile hacks. 1493

When you have ringing of the ears, seeing stars, that's a concussion.

President Donald Trump’s supporters have seized on a photo circulating on Twitter since late Sunday that shows Democratic presidential nominee Joe Biden not wearing a mask while he talks to a campaign staffer on a plane. Why wasn’t Biden, who has made a point to put on a facial covering throughout the campaign, wearing a mask? Because the photo was taken in November 2019, before the first case of the new coronavirus was reported, and months before global health officials began urging people to wear masks in order to stop the spread of the virus. 559
