The timelines on your Instagram accounts have probably been flooded recently with women posting black-and-white pictures of themselves.The premise of the viral trend comes as a way for women to support each other with the accompaniment of the hashtag #ChallengeAccepted in their caption.The origins of the first picture used in the trend were traced by Taylor Lorenz of The New York Times. Lorenz found that a journalist in Brazil posted the very first picture in the challenge.There had been reports that the challenge first began in order to bring awareness about femicide in Turkey, but Lorenz spoke to Instagram and tweeted that the hashtag in Turkey and the United States were unrelated. 700

The spread of COVID-19 is tough to trace and even tougher to predict, but researchers at Pittsburgh’s Carnegie Mellon University created an early warning system to help protect you from the virusMathematics professor Po-Shen Loh developed an app called NOVID, a contact-tracing app, to help communities see the virus coming before they get infected.On top of creating a brand new app, Loh teaches math to middle-school students online from his own office-turned-broadcast studio. He’s also the national coach for the United States Math Olympiad team that competes around the world.But when the pandemic hit, Loh wanted to take on one more project. “I like things that are supposed to be impossible, that can’t be done,” said Loh. Stopping the spread of the coronavirus seemed to fit the bill.“The problem with COVID is it spreads before you know you have it, that’s what makes COVID different," Loh said. "The only way you can control this disease is in helping people to know whether or not COVID is coming close to them in advance."That’s where the NOVID app can help, said Loh. “Shows the virus coming towards you based on your relationship network, so that you can protect yourselves from others before you actually get infected," Loh explained of the app. "This is in contrast to most other contact tracing apps that are designed to protect others from you."The app shows you positive cases in degrees of separation. A positive case in the first degree would be someone you live with. The second degree could be your coworker or a friend. The third degree would be that person’s spouse or child. Each degree of separation is a possible pathway for you to come in contact with COVID-19.“This thing shows you the virus coming towards you, kind of like a hurricane satellite shows you a hurricane coming towards you,” said Loh.In addition to showing you cases as they pop up around you, the app can track the distance between phones down to the inch.It uses both Bluetooth and ultrasound waves to give you that measurement to make sure you’re safely social distancing.“We don’t know of any other contact-tracing app in the entire world which will tell you, ‘here’s how far away we think the device was,’” said Loh.The safety of your personal information is one of the most important features of this app. It collects data, while you stay completely anonymous.“Many people are distrustful of an app that does contact tracing,” said Loh. “We never ask for your phone number or email."Those who are positive can self-report their case in the app. Loh is also working with cities and counties to integrate NOVID into health departments across the country. He said the health departments would issue a ticket with a number to each person who tests positive for the virus.That person would enter the number into their NOVID app, anonymously reporting the positive case in the community.“If this thing actually caught on, you’d see in all the cities and towns, whether it’s rural or urban, whenever COVID starts to rise up, you’d start to see everyone take caution. Not because anyone forced them to, but because they saw this is what would be useful,” said Loh.To create the powerful community resource Loh is hoping for, he said more people need to know about the app.“Right now, we only respond when the intensive care units are full, and then it’s too late, and people die on the sidewalk. But, what we wish would happen, is that people could see it coming, and then, everyone starts to be careful at the right time. With more traction, we can save more lives,” he said.Loh is hoping he can not only help save lives but help bring back life as we knew it.“The goal of what we’re trying to do is to give people headlights to drive in the dark. Our app is not designed to let other people control you; our app is designed to help you control your life,” said Loh.For more information on NOVID or to download it, click HERE. 3928

The US Air Force apologized Thursday for its ill-advised attempt to incorporate the viral "Yanny" or "Laurel" meme into a tweet about repelling a Taliban attack in Afghanistan.In what was clearly a major social media fail, the initial tweet -- which was posted by the Air Force's official account earlier in the day -- attempted to put a playful spin on the popular meme currently sweeping the internet by comparing it to the distinctive sound of the 30mm cannons aboard an A-10 Warthog aircraft."The Taliban Forces in Farah city #Afghanistan would much rather have heard #Yanny or #Laurel than the deafening #BRRRT they got courtesy of our #A10," the tweet said.The tweet has since been deleted and replaced with an apology that said the initial post was "made in poor taste.""We apologize for the earlier tweet regarding the A-10. It was made in poor taste and we are addressing it internally. It has since been removed," the second post said.Politicians, corporate brands and even the Department of Defense's official Twitter account have weighed in on the debate centered around a viral audio clip that says either "Yanny" or "Laurel" depending on the listeners interpretation.But the Air Force's post incorporating the pop-culture reference sparked criticism from those who said it was inappropriate to mention the meme in a tweet about the thwarted Taliban attack .When asked about the controversy on Thursday, Pentagon Spokeswoman Dana White said she wasn't aware of the tweet."What is important to understand is that this is the Afghans' fight. We are working by, with and through these partners. And they are dying to secure their own future and I think that shouldn't be forgotten in any of this," she added.The US military helped Afghan troops repel a major Taliban attack on the Afghan provincial capital Farah on Tuesday and Wednesday that punctured the security perimeter surrounding the city, US and NATO officials told CNN.The Pentagon said Thursday some US advisers assisted in the fight and coalition airstrikes also took place. US A-10 attack jets also flew overhead but did not conduct any strikes.It was unclear how close the Taliban came to capturing the city, which would have represented a major blow to the Afghan government.The insurgents claimed they briefly seized the city center, while the NATO-led coalition said it saw no direct evidence that they ever made it into the city.Afghan A-29 attack planes and Mi-17 helicopters carried out multiple airstrikes in defense of the city.US military advisers eventually arrived in the city to assist Afghan military commanders at their headquarters, helping to call in drone strikes that killed some 28 Taliban fighters, Lt. Col. Martin O'Donnell told CNN.He said US troops also arrived to advise Afghan commando units involved in the counterattack but did not participate in offensive operations. 2877

The Scottish Parliament voted on Tuesday to unanimously approve a bill that would provide free feminine hygiene products to the public. The bill says products that are disposable, such as tampons and wipes, will be available to the public for free.The legislation, titled SP Bill 45A, spells out that local authorities ensure “period products” be obtainable free of charge to all persons who need them; education providers make period products obtainable for free for students; and that period products be available for free in public buildings.The legislation points out that Scotland is the first nation in the world to implement such a law, so it is unknown what the cost might be to the government.The Scottish government estimates there are nearly 1.6 million women of menstruation age in Scotland.“Thank you to everyone who has campaigned for period dignity and to my MSP colleagues for backing the Bill tonight. A proud day for Scotland and a signal to the world that free universal access to period products can be achieved,” the bill’s sponsor Monica Lennon tweeted."Proud to vote for this groundbreaking legislation, making Scotland the first country in the world to provide free period products for all who need them. An important policy for women and girls," Scotland's First Minister Nicola Sturgeon said on Twitter. 1337
