The CEOs of Twitter, Facebook and Google are facing a grilling by Republican senators making unfounded allegations that the tech giants show anti-conservative bias.The Senate Commerce Committee has summoned Twitter CEO Jack Dorsey, Facebook’s Mark Zuckerberg and Google’s Sundar Pichai to testify for a hearing Wednesday. The executives agreed to appear remotely after being threatened with subpoenas.With the presidential election looming, Republicans led by President Donald Trump have thrown a barrage of grievances at Big Tech’s social media platforms, which they accuse without evidence of deliberately suppressing conservative, religious and anti-abortion views.The chorus of protest rose this month after Facebook and Twitter acted to limit dissemination of an unverified political story from the conservative-leaning New York Post about Democratic presidential nominee Joe Biden, an unprecedented action against a major media outlet. The story, which was not confirmed by other publications, cited unverified emails from Biden’s son Hunter that were reportedly disclosed by Trump allies.Beyond questioning the CEOs, senators are expected to examine proposals to revise long-held legal protections for online speech, an immunity that critics in both parties say enables the companies to abdicate their responsibility to impartially moderate content.The Justice Department has asked Congress to strip some of the bedrock protections that have generally shielded the tech companies from legal responsibility for what people post on their platforms. Trump signed an executive order challenging the protections from lawsuits under the 1996 telecommunications law.“For too long, social media platforms have hidden behind Section 230 protections to censor content that deviates from their beliefs,” Sen. Roger Wicker, R-Miss., the Commerce Committee chairman, said recently.In their opening statements prepared for the hearing, Dorsey, Zuckerberg and Pichai addressed the proposals for changes to so-called Section 230, a provision of a 1996 law that has served as the foundation for unfettered speech on the internet. Zuckerberg said Congress “should update the law to make sure it’s working as intended.”“We don’t think tech companies should be making so many decisions about these important issues alone,” he said, approving an active role for government regulators.Dorsey and Pichai, however, urged caution in making any changes. “Undermining Section 230 will result in far more removal of online speech and impose severe limitations on our collective ability to address harmful content and protect people online,” Dorsey said.Pichai urged lawmakers “to be very thoughtful about any changes to Section 230 and to be very aware of the consequences those changes might have on businesses and consumers.”Assistant Attorney General Stephen Boyd told congressional leaders in a letter Tuesday that recent events have made the changes more urgent. He cited the action by Twitter and Facebook regarding the New York Post story, calling the companies’ limitations “quite concerning.”The head of the Federal Communications Commission, an independent agency, recently announced plans to reexamine the legal protections, potentially putting meat on the bones of Trump’s order by opening the way to new rules. The move by FCC Chairman Ajit Pai, a Trump appointee, marked an about-face from the agency’s previous position.Social media giants are also under heavy scrutiny for their efforts to police misinformation about the election. Twitter and Facebook have slapped a misinformation label on content from the president, who has around 80 million followers. Trump has raised the baseless prospect of mass fraud in the vote-by-mail process.Starting Tuesday, Facebook was not accepting any new political advertising. Previously booked political ads will be able to run until the polls close next Tuesday, when all political advertising will temporarily be banned. Google, which owns YouTube, also is halting political ads after the polls close. Twitter banned all political ads last year.Democrats have focused their criticism of social media mainly on hate speech, misinformation and other content that can incite violence or keep people from voting. They have criticized Big Tech CEOs for failing to police content, homing in on the platforms’ role in hate crimes and the rise of white nationalism in the U.S.Facebook, Twitter and YouTube have scrambled to stem the tide of material that incites violence and spreads lies and baseless conspiracy theories.The companies reject accusations of bias but have wrestled with how strongly they should intervene. They have often gone out of their way not to appear biased against conservative views — a posture that some say effectively tilts them toward those viewpoints. The effort has been especially strained for Facebook, which was caught off-guard in 2016, when it was used as a conduit by Russian agents to spread misinformation benefiting Trump’s presidential campaign.The unwelcome attention to the three companies piles onto the anxieties in the tech industry, which also faces scrutiny from the Justice Department, federal regulators, Congress and state attorneys general around the country.Last week, the Justice Department sued Google for abusing its dominance in online search and advertising — the government’s most significant attempt to protect competition since its groundbreaking case against Microsoft more than 20 years ago.With antitrust in the spotlight, Facebook, Apple and Amazon also are under investigation at the Justice Department and the Federal Trade Commission.___Follow Gordon at https://twitter.com/mgordonap. 5687

The colors of an autumn afternoon can be serene, brilliant and breathtaking.“As the days start getting shorter and the nights get longer, that's the cue that the trees get to change the foliage,” said climate scientist Astrid Caldas.That foliage requires a delicate dance of temperature and moisture to produce fall colors. It’s a dance potentially now in jeopardy due to climate change.“Because these things -- temperature and precipitation, rainfall -- are being affected, changed by climate, then the fall foliage can really get affected,” said Caldas, who is a senior climate scientist at the Union of Concerned Scientists, a nonprofit science organization.She said long-term shifting temperature trends and more rain will be disruptive to fall foliage in certain parts of the country.“We are seeing extreme precipitation increase, particularly in the Northeast and the Midwest,” Caldas said.That precipitation was evident in Minnesota, where people found themselves caught off-guard this year by an unusually early snowfall."I had to completely disassemble my fall leaf clean-up box and make sure my plow is still working,” said Greg Futchi, who is a landscape contractor. “We usually get all the leaves down before we see some snow, but not this year."All of that added moisture can lead to a shorter fall foliage season, Caldas said. Yet, repeated and ongoing droughts, like those seen in the western U.S., also bring their own set of problems to autumn leaves.“When it’s very dry, the colors get a little more muted also,” Caldas said. “So, drought can really kind of change completely the setup.”Scientists add that climate change isn’t just going to affect the ways leaves change their colors during the fall. It’s also going to potentially affect where those trees grow in the first place.“When the conditions start changing --like it's starting to get warmer further and further north--well, that's also a possibility that species are going to start migrating farther north,” Caldas said. “So, as different trees start moving to different areas, then the colors may change because the color depends on the tree.”That may mean having to travel farther north to see stunning red maples. It is a change that will be hard to stop unless action is taken on a global scale.“In the long run, if the countries and the whole world is not committed to really reducing emissions and changing to renewables and making that complete change, then it's going to be very hard for us not to see very drastic changes, because small changes are already happening,” Caldas said.Those changes are now encroaching on a time-honored spectacle, courtesy of Mother Nature. 2667

The death of another Fort Hood soldier is under investigation after he was found unresponsive at a nearby lake.On Friday, July 17 at 12:07 a.m., deputy’s with the Bell County Sheriff’s Department were dispatched to the area of the Stillhouse Hollow Lake Dam after fishermen in a boat located what they believed to be a body in the water at the base of the dam.Upon arrival, deputy’s found the body 26-year-old Pvt. Mejhor Morta was located in the vicinity of Stillhouse Hollow Lake — located about 15 miles east of the Army base.An autopsy was ordered by Justice of the Peace Garland Potvin.A preliminary autopsy shows the cause of death to be consistent with drowning, but at this time, a full autopsy report has not been completed or released by the Medical Examiner’s Office in Dallas, Texas.Morta's body was found just weeks after officials found the dismembered remains of Pfc. Vanessa Guillen — a soldier stationed on Fort Hood who went missing in April. Officials have not said that the two cases are linked.Morta was from Pensacola, Florida, and entered the Army in September 2019, as a Bradley Fighting Vehicle mechanic. He has been assigned to 1st Battalion, 5th Cavalry Regiment, 2nd Armored Brigade Combat Team, 1st Cavalry Division, since May 2020.Friends of Morta say his family is from the Philippines."I reached out to his sister today and they are currently in the Philippines," said Hunter Proffitt, a friend of Morta. "He literally came over here, he joined the U.S. Army to help move his family over here. He wanted to move his family. He wanted to make a better life for himself and then we find out that this happens."The Bell County Sheriff’s Department continues their investigation and no other information is available for release at this time.This story was originally published by Sydney Isenberg on KXXV in Waco, Texas. 1856

The Centers for Disease Control and Prevention's own medical advisers are criticizing the federal health agency for being slow to respond to a polio-like disease that's struck hundreds of children over the past six years."Frustrated and disappointed -- I think that's exactly how most of us feel," said Dr. Keith Van Haren, one of the CDC advisers on AFM and an assistant professor of neurology at the Stanford University School of Medicine.Van Haren and other doctors who care for these children say the agency has been slow to gather data and to guide pediatricians and emergency room physicians on how to diagnose and treat the children struck with the disease, acute flaccid myelitis."This is the CDC's job. This is what they're supposed to do well. And it's a source of frustration to many of us that they're apparently not doing these things," said Dr. Kenneth Tyler, a professor and chair of the department of neurology at the University of Colorado School of Medicine and another adviser to the CDC on AFM. 1022

The coronavirus pandemic has already caused depleted toilet paper shelves and concerns about meat shortages, but now it’s also to blame for some other, maybe more surprising shortages across the country.Coca-Cola announced at the beginning of July that it was stopping production on Odwalla Juice at the end of the month. On a call with investors, James Quincey, Chairman & Chief Executive Officer of The Coca-Cola Co. said of Odwalla, “In the case of a brand like Odwalla and its chilled direct store delivery, which has struggled over the last several years, we started to stop operations effective July 31. This gives us the flexibility to support our investments in brands like Minute Maid and Simply.”And if you thought you were imagining fewer types of Coke products on store shelves, there’s a good chance you weren’t. A representative from the soft drink giant said in an email, “We continue to see high demand for products consumed at home. We are implementing contingency plans as best we can to get the products people want to store shelves. We appreciate everyone’s patience as we work through these unprecedented times,” going on to say, “we are focusing on the availability of our most popular brands.”“Coke is facing is a different sort of thing right now; it's something that's a shift in demand, which is temporary, and they're not in position to respond to it other than to…put all of their eggs into the baskets that are going out the door fastest,” said William Dickens, University Distinguished Professor and chair of the economics department at Northeastern University.Another issue for Coke likely ties into another shortage – aluminum cans.According to Robert Budway, the president of the Can Manufacturers Institute, the aluminium can industry was seeing demand increase even before the pandemic began because cans are more environmentally friendly than plastic bottles, and the demand has only gone up.“Can manufacturers are fully focused on filling the extraordinary demand from all sectors of the industry’s customer base,” said Budway in a statement. He also said that although there is enough aluminum, can makers have announced the construction of several new plants in the United States and Canada, but they will take between 12 and 18 months to build.Chains like Taco Bell announced they’re trimming the menu too, removing things like the 7-Layer Burrito and Nachos Supreme. And Red Robin Gourmet Burgers ditched a third of its menu.The national burger chain cut 55 items, and a representative pointed to what they told their investors about the changes saying the cuts have resulted in “faster cook times, higher quality food” and say it’s reduced waste.“Sure,” said Dickens. “But why wouldn't they have done it before this, if it made such a big difference? The best explanation is that now they're in a different circumstance, and they just can't afford to produce the type of variety that they did before because they aren't having as many people coming in.”Dickens said everything, each menu item and each flavor of soda, has a specific cost to make. For a business to be profitable, it has to sell a certain number of each offering.So it makes sense that less popular items might hit the road right now.“As for menus and shortages…I think we may very well see more firms follow suit. I know my favorite restaurant is only offering a couple of items compared to what it used to. So I know it's a phenomenon that's out there,” said Dickens. “It's more profitable for [restaurants] to focus on a couple of items that they know that they're going to sell a lot of.”He went on to say what we can expect to see in the next month or year largely depends on how things go with COVID-19 and the subsequent handling of the economy.“I guess my biggest fear is that we're mishandling the economy,” said Dickens.He said that the United States’ economy hasn’t shrunk as much as it might have since the pandemic hit because Congress authorized an extra 0 per week for unemployment benefits. He said that the people who are getting those benefits are also then spending that money on things like food and drink.With the final unemployment supplements already distributed, Dickens predicts people will have less money to spend, which in turn will mean less money in the economy overall, more job layoffs – and a deeper recession. He said that could ultimately mean more shortages – and more businesses closing for good.“We should not let the smart things that were done fade away too early, and this is clearly too early since a large part of the country is still seeing growing numbers of cases,” said Dickens. “They're probably going to have to take action to pull back from re-opening and people are gonna need economic support.” 4769
