Twitter is about to get more words -- a lot more.The company announced on Tuesday it is doubling how many characters users can cram into a tweet.Most tweets will now fit 280 characters, up from 140. The new limit will roll out to Twitter users in almost all 40 languages Twitter supports.In late September, Twitter began a test of 280-character tweets with a small group of users.Like many Twitter changes, some users complained about the move.Interestingly, Twitter said that after the novelty of tweeting more characters wore off, most people in the test stopped tweeting the full length.According to the company, only 5% of tweets sent from people in the 280-character test group were longer than 140 characters, and just 2% were over 190 characters.The new character length won't apply to Japanese, Korean or Chinese-language tweets. Those languages can convey twice as much information in less space, so tweets will remain at 140 characters, Twitter said.Of course, the change means America's highest-profile Twitter user, President Trump, will have more space. Twitter cofounder Biz Stone had said the prolific Twitter user was not in the test group.The move modifies a fundamental aspect of Twitter. Aside from the test, the social network's character limit hasn't changed since the company launched in 2006.The 140-character length wasn't a random choice: Twitter's founders wanted tweets to fit in a text message, which can only hold 160 characters. So Twitter chose 140 characters for the tweet, and 20 characters for the user name.During the 280-character test, some users argued Twitter should focus less on the length of the tweets and more on the content. The platform continues to be rife with harassment and abuse, despite the company's efforts to better police it.Twitter recently updated its rules to be more explicit in its definitions and policies towards harassment, threats, and adult content.Everyone affected by the new length should have it by Tuesday evening.The-CNN-Wire 2005

URBANA-CHAMPAIGN, Ill. – As colleges and universities are tasked with safely beginning classes, researchers at one school are ramping up testing. But they're putting away the nasal swab in exchange for a test they say can be scaled to perform thousands of tests a day with turnaround in just hours.College junior Alliyah Rumbolt-Lemond is already back on campus and regularly testing for COVID-19.“I know if you have in-person classes, you're going to be on campus, you have to get tested twice a week,” she says.The college junior is one of the more than 51,000 students at the University of Illinois at Urbana-Champaign returning to school during the pandemic, posing a logistical challenge for administrators.“It was very daunting,” said U of I chemistry professor Marty Burke.He was part of the team of university researchers who developed a two-step saliva-based COVID-19 test to tackle the problem.“We called this our ‘target, test and tell’ initiative, overall collectively described as a ‘Shield.’”The Shield Initiative needed to be scalable, and unlike the four-step nasopharyngeal swab tests, not vulnerable to supply chain bottlenecks.“It's a very powerful concept that if we can get to that fast, frequent testing, we really could get control of the situation,” said Burke.A quick stop on route to class or work, integrated with local health care agencies, students receive results on an app within hours, not days.“It takes about five to ten minutes to submit your saliva sample and then the results are typically back on your phone within three to six hours,” said Burke.The university’s veterinary school diagnostic lab has been converted into a full-scale human COVID-19 testing facility. It’s capable of processing some 10 to 20,0000 saliva tests per day.“I want to hang out with friends and do it the right way, like following CDC guidelines,” said Alliyah. “But I feel more comfortable saying ‘hey when's the last time you got tested?’”A total of 20 testing sites with 40 stations are set up across campus. Users can even get exposure notifications if they’ve been in contact with someone who tests positive.“If someone tests positive then same day that person is isolated,” said Burke. “Which we think is critical for ultimately the efficacy of the testing program.”They’ve published a pre-print paper on their COVID-19 saliva test, which is undergoing peer review and are seeking FDA approval.For students like Alliyah, it’s one-stop piece of mind.“It makes you feel like I'm safer on campus because even though we only have to get tested twice a week you can get tested every day the testing site is open if you wanted to.” 2653

UNITED NATIONS (AP) — The U.N. health chief says positive results from coronavirus vaccine trials mean the world “can begin to dream about the end of the pandemic.” But the director-general of the World Health Organization says rich and powerful nations must not trample the poor and marginalized “in the stampede for vaccines.” Tedros Adhanom Ghebreyesus told the General Assembly’s first high-level session on the pandemic that while the virus can be stopped, “the path ahead remains treacherous.” Tedros said Friday that the pandemic has shown humanity at “its best and worst,” pointing to acts of compassion and scientific achievements but also “signs of self-interest, blame-shifting, and divisions.” 713
