Mark Zuckerberg has taken the stage to deliver a keynote at F8, Facebook's annual developer's conference.The CEO addressed Facebook's ongoing data privacy scandal, election meddling issues, and fake news problems, recapping the company's efforts to fix those problems. But he also tried to move the narrative forward with new product and feature announcements."We are all here because we are optimistic about the future," said Zuckerberg. "We have real challenges to address but we have to keep that sense of optimism too. What I learned this year is we have to take a broader view of our responsibility."Zuckerberg called out "Watch Party," a tool announced in January that lets you watch shows while chatting about them with your Facebook friends."Let's say that your friend is testifying in congress, for example. Now you're going to be able to bring your friends together and you can laugh together and you can cry together. Some of my friends actually did this! Let's not do that again anytime soon," Zuckerberg said.And Facebook is adding new features for dating, Zuckerberg announced."This is going to be for building real long term relationships, not just hookups, it's going to be in the Facebook app but it's totally optional. It's opt in... we have designed this with privacy and safety in mind from the beginning... you will only be suggested people who are not your friends."The event comes more than a month after news broke that Cambridge Analytica, a data firm with ties to President Donald Trump's campaign, accessed information from as many as 87 million Facebook users without their knowledge.Shortly before Zuckerberg's keynote began, the company announced a new privacy feature that will, once launched, allow users to clear their browsing history on Facebook, including what they've clicked on and which websites they've visited.  1865

Maybe music artist Moby was right, and “we are all made of stars.” New research suggests the calcium in our teeth and bones came from star explosions.Researchers from Northwestern University looked at a calcium-rich supernova with x-ray imaging, which provided a glimpse into the last month of the star’s life and ultimate explosion.The findings, published in The Astrophysical Journal, suggest a calcium-rich supernova is a compact star that gives off an outer layer of gas as it’s dying. When it explodes, the star’s matter collides with material, emitting bright x-rays.The explosion is so intensely hot and high pressure, it allows nuclear fusion to produce a massive amount of calcium in mere seconds. Typically, a star creates a small amount of calcium slowly by burning helium.Half the calcium in the universe likely came from calcium-rich supernovae.“These events are so few in number that we have never known what produced calcium-rich supernova,” said Wynn Jacobson-Galan, a first-year Northwestern graduate student who led the study. “By observing what this star did in its final month before it reached its critical, tumultuous end, we peered into a place previously unexplored, opening new avenues of study within transient science.”The observed explosion was named SN 2019ehk in the Messier 100 galaxy. If that sounds a little too fantasy, just know it was 55 million light years from earth.“Without this explosion, you wouldn’t know that anything was ever there,” Margutti added. “Not even Hubble could see it.”The team was able to look at images from the Hubble Telescope of the area of SN 2019ehk before the explosion to compare before and after.The researchers are working on a follow-up study that includes how the supernova is evolving after the explosion, according to statements made to CNN. 1821

Military suicides have increased by as much as 20% this year compared to the same period in 2019, and some incidents of violent behavior have spiked as service members struggle under COVID-19, war-zone deployments, national disasters and civil unrest.While the data is incomplete and causes of suicide are complex, Army and Air Force officials say they believe the pandemic is adding stress to an already strained force.And senior Army leaders — who say they’ve seen about a 30% jump in active duty suicides so far this year — told The Associated Press that they are looking at shortening combat deployments. Such a move would be part of a broader effort to make the wellbeing of soldiers and their families the Army’s top priority, overtaking combat readiness and weapons modernization.The Pentagon refused to provide 2020 data or discuss the issue, but Army officials said discussions in Defense Department briefings indicate there has been up to a 20% jump in overall military suicides this year. The numbers vary by service. The active Army’s 30% spike — from 88 last year to 114 this year — pushes the total up because it’s the largest service. The Army Guard is up about 10%, going from 78 last year to 86 this year. The Navy total is believed to be lower this year.Army leaders say they can’t directly pin the increase on the virus, but the timing coincides.“I can’t say scientifically, but what I can say is - I can read a chart and a graph, and the numbers have gone up in behavioral health related issues,” Army Secretary Ryan McCarthy said in an AP interview.Pointing to increases in Army suicides, murders and other violent behavior, he added, “We cannot say definitively it is because of COVID. But there is a direct correlation from when COVID started, the numbers actually went up.”Preliminary data for the first three months of 2020 show an overall dip in military suicides across the active duty and reserves, compared to the same time last year. Those early numbers, fueled by declines in Navy and Air Force deaths, gave hope to military leaders who have long struggled to cut suicide rates. But in the spring, the numbers ticked up.“COVID adds stress,” said Gen. Charles Brown, the Air Force chief, in public remarks. “From a suicide perspective, we are on a path to be as bad as last year. And that’s not just an Air Force problem, this is a national problem because COVID adds some additional stressors – a fear of the unknown for certain folks.”The active duty Air Force and reserves had 98 suicides as of Sept. 15, unchanged from the same period last year. But last year was the worst in three decades for active duty Air Force suicides. Officials had hoped the decline early in the year would continue.Navy and Marine officials refused to discuss the subject.Civilian suicide rates have risen in recent years, but 2020 data isn’t available, so it’s difficult to compare with the military. A Pentagon report on 2018 suicides said the military rate was roughly equivalent to that of the U.S. general population, after adjusting for the fact that the military is more heavily male and younger than the civilian population. The 2018 rate for active duty military was 24.8 per 100,000, while the overall civilian rate for that year was 14.2, but the rate for younger civilian men ranged from 22.7 to 27.7 per 100,000, according to the National Institute of Mental Health.James Helis, director of the Army’s resilience programs, said virus-related isolation, financial disruptions, remote schooling and loss of child care all happening almost overnight has strained troops and families.“We know that the measures we took to mitigate and prevent the spread of COVID could amplify some of the factors that could lead to suicide,” said Helis, who attended department briefings on suicide data.Army leaders also said troops have been under pressure for nearly two decades of war. Those deployments, compounded by the virus, hurricane and wildfire response and civil unrest missions, have taken a toll.Soldiers’ 10-month deployments have been stretched to 11 months because of the two-week coronavirus quarantines at the beginning and end. McCarthy said the Army is considering shortening deployments.Gen. James McConville, Army chief of staff, said there’s new attention to giving service members “the time that they need to come back together and recover.”“We were very focused on readiness four years ago because we had some readiness challenges, and we did a great job. The force is very, very ready now. But I think it’s time now to focus on people,” he told the AP.McConville and Army Sgt. Maj. Michael Grinston said units have begun “stand-up” days, where commanders focus on bringing people together, making sure they connect with each other and their families and ensuring they have strong values in how they treat each other.The isolation is also taking a toll on veterans, particularly the wounded.Sergio Alfaro, who served in the Army for 4 1/2 years, said fears associated with the virus intensified his PTSD and suicidal thoughts.“It’s definitely something that’s made things a bit more chaotic, trying to plan for the future, do things together,” said Alfaro, who deployed near Baghdad in 2003, facing daily mortar rounds, including one that killed his commander. “It’s almost like adding more trash on the heap.”While he once feared that strangers passing by might hurt him, now he fears people may have COVID and not show symptoms. Others in support groups, he said, “are just sick of living this way, worried about what’s coming over the next hill, what next horrible thing are we going to be confronted with.”Roger Brooks, a senior mental health specialist at the Wounded Warrior Project, said veterans are reporting increased suicidal symptoms and anxiety. Between April and the end of August, the group saw a 48% jump in referrals to mental health providers and a 10% increase in mental health calls and virtual support sessions, compared to the previous five months.Brooks said there’s anecdotal evidence that the pandemic has made wounded warriors like amputees feel more isolated, unable to connect as well with support groups. He said injured vets have seen disruptions in medical visits for pain management and other treatments.Within the Army, Helis said the virus has forced an increase in telehealth calls and online visits with mental health providers. That has generated some positive results, such as fewer missed appointments.“And we also think there was a reduction in the stigma of seeking behavioral health because you can do it from the privacy of your home,” he said.Military leaders also are encouraging troops to keep a closer eye on their buddies and ensure that those who need help get it.That message was conveyed in a remarkable public statement this month by Gen. John Hyten, vice chairman of the Joint Chiefs of Staff. He said he sought help while heading U.S. Strategic Command from 2016 to 2019. He didn’t reveal details but said he saw a psychiatrist – a rare public admission by a senior officer.“I felt like I needed to get some help,” Hyten said in a video message. “I felt like I needed to talk to somebody.” He encouraged others to do the same, if needed, without fear of hurting their career._____ Need help?
