Every morning, Philip Staroska starts his day by logging onto his computer and wishing his class of kindergarten students in Phoenix, Arizona a good morning. The spiking COVID-19 cases have kept this life-long educator out of the classroom for longer than he could’ve ever imagined.There are days when all Staroska wants to do is give his students a hug or a high five, but instead, a virtual pat on the back over Zoom has to suffice.“I would give anything to give my kids a high five, a hug, to be able to be like, ‘hey, come on, focus.’ It’s a lot more powerful in-person than over the screen,” Staroska said.And yet, for as much as he longs to be in the classroom, Staroska knows with COVID-19 cases reaching record-high levels in his county, keeping kids and their families safe is taking precedent right now.“I would love for it to be a normal school year, but it’s not,” he added.It’s been long, challenging year for teachers like Staroska across the country. Regardless of whether learning is occurring in-person or virtually, many educators are worried the pressures of the pandemic are dramatically impacting student’s academic progress.“It’s just not the same as being in the classroom,” Staroska said.His sentiments are shared by other teachers and administrators, trying their best to navigate the challenges of learning during a pandemic.In Nashville, Tennessee, Dr. Kenyae Reese, a high school principal, is worried about the emotional impact this year is having on her high school students. In many cases, students are now taking part-time jobs to help parents who may have lost their jobs due to the pandemic.“We’re seeing high school kids who have to watch little siblings because their parents are out of work. It’s then juggling being a student, but I also have to monitor a younger sister or brother. There’s a lot more responsibility,” the principal said.“Sometimes kids are working during the day because they may be one of the breadwinners, especially right now,” she added.Another concern: attendance, especially among students who are starting to experience burnout.“Even kids who are super strong with social media and technology are struggling. We just didn’t anticipate having to go this long.” 2230

Elon Musk's latest big idea is daring even by his standards: He wants to turn Tesla into a private company.He stunned investors on Tuesday with a tweet saying he had already lined up the funding, and he told employees that it would relieve the electric car company of the "enormous pressure" of Wall Street's expectations.In a letter to Tesla workers that was posted on the company's blog, Musk called his idea the "best path forward.""As a public company, we are subject to wild swings in our stock price that can be a major distraction for everyone working at Tesla, all of whom are shareholders," he wrote.He also said trading its stock publicly "means that there are large numbers of people who have the incentive to attack the company." Musk has complained repeatedly about short-sellers, who profit when Tesla stock drops.Musk, the CEO and largest shareholder, said on Twitter that the private funding valued Tesla at 0 per share. Tesla is already the most valuable automaker in the United States.The early afternoon tweet sent Tesla stock spiking by almost 9%. Trading in Tesla was halted for more than an hour before Tesla posted Musk's letter to employees on its blog. It finished up 11%, at 9.The stock had climbed slightly earlier in the day after the Financial Times reported that Saudi Arabia has quietly built a big stake in the company.At first, Tesla had declined comment on Musk's tweet, even as he casually engaged Twitter followers with more posts about his plans.Musk said that he hoped all current investors would stay with Tesla even if it went private. He said he would create a special fund to allow that. Fidelity, the investment firm, has such a fund for its stake in SpaceX, a separate private company also run by Musk.He pledged to hold on to his stake in the company, about 20%, no matter what. He said he was "super appreciative" of Tesla shareholders, and vowed to "ensure their prosperity in any scenario."Tesla has burned through cash while struggling to produce the Model 3, its lowest-priced electric car. That has driven the stock lower and raised concerns about whether Tesla will need to sell more shares to pay for expansion. Musk has insisted Tesla has no such need.Musk has also clashed repeatedly with critics, especially investors who have taken short positions on the stock, meaning they benefit when the price falls. He clashed with analysts on a contentious call after Tesla reported earnings three months ago.Gene Munster, managing partner at Loup Ventures and a top tech analyst, said the odds that Musk will take Tesla private were about one in three. But he said the idea made a certain amount of sense."Musk does not want to run a public company," Munster wrote on his website. "His mission for Tesla (to accelerate the globe's adoption of sustainable energy) is both grand and long-term, making it difficult to accommodate investors quarterly expectations."It would cost about billion to take Tesla private at 0 per share. Before Musk's tweet, Tesla had a market value of billion, already higher than that of General Motors or Ford, even though those companies are significantly larger and more profitable.In fact, Tesla has turned a narrow profit in only two quarters since it became a public company in 2010. Musk has vowed that the company will start turning a regular profit in the second half of this year.In a 2013 report, the SEC said companies can use social media outlets to announce important information, so long as they comply with regulations and "investors have been alerted about which social media will be used to disseminate such information."The SEC issued that report after Reed Hastings, the CEO of Netflix, used a Facebook post to congratulate Netflix's chief content officer on record-breaking viewership. Netflix stock moved higher as a result.Tesla said in a regulatory filing in 2013 that investors interested in keeping up with Tesla should follow Musk's account.The SEC declined comment on Musk's tweet.Musk has a history of outrageous behavior on Twitter.On April 1, amid rising market concerns about a cash crunch at Tesla, he tweeted an email announcing that Tesla would have to file for bankruptcy. The tweet was apparently an April Fool's joke.Musk also faced intense public criticism after he suggested in a tweet that one of the rescuers of the Thai soccer team trapped in a cave was a pedophile.He later deleted that tweet and apologized for that exchange, but at least one analyst suggested Musk needed to get off Twitter to restore investor confidence in the company.After Musk, the next largest shareholders in Tesla are the mutual fund giants T. Rowe Price and Fidelity, with stakes of more than 9% and 8%, respectively, according to Thomas Reuters Eikon.Scottish money manager Baillie Gifford, which recently urged Musk to focus less on tweeting and more on running the business, is the fourth-largest shareholder, with a nearly 8% stake. Chinese tech giant Tencent owns almost 5%.James Anderson, a Baillie Gifford fund manager who recently called out Musk's tweeting in an interview with Bloomberg, had no comment about Musk's tweets on Tuesday. Fidelity and T. Rowe Price also declined comment.— CNNMoney's Donna Borak contributed to this report.The-CNN-Wire 5277

Ethan Melzer, a 22-year-old US Army private, has been indicted for allegedly plotting a “mass casualty” attack on his Army unit.In its announcement of the indictment, the Department of Justice said that Melzer was sending sensitive military information to members of a neo-Nazi group to help facilitate the attack.Melzer has been charged with conspiring and attempting to murder U.S. nationals, conspiring and attempting to murder military service members, providing and attempting to provide material support to terrorists, and conspiring to murder and maim in a foreign country.The DOJ said that the FBI thwarted the attack in May 2020 before arresting Melzer on June 10.The DOJ said that Melzer was a member of O9A, a group that officials say has participated in acts of violence.Melzer was informed of his unit’s deployment in April 2020. The DOJ said that Melzer then used an encrypted message application to send messages to O9A. The group allegedly planned a “jihadi attack” during the unit’s deployment.“As alleged, Ethan Melzer, a private in the U.S. Army, was the enemy within,” Acting U.S. Attorney Audrey Strauss said. “Melzer allegedly attempted to orchestrate a murderous ambush on his own unit by unlawfully revealing its location, strength, and armaments to a neo-Nazi, anarchist, white supremacist group. Melzer allegedly provided this potentially deadly information intending that it be conveyed to jihadist terrorists. As alleged, Melzer was motivated by racism and hatred as he attempted to carry out this ultimate act of betrayal.”Melzer could face life in prison if convicted on the counts. 1620

ESCONDIDO, Calif. (KGTV) — First it was toilet paper and now there are reports of a shortage of outdoor recreational equipment, specifically kayaks. But one local business owner says San Diego is ready to meet the demand during the COVID pandemic. Bruce Damon, the owner of Nomad Ventures in Escondido, says after a 10-week shutdown they are back serving outdoor enthusiasts."We're just hoping that people can get out and enjoy themselves safely, and kayaking was one of the first things that I understood was considered a safe endeavor," says Damon.In what came as a surprise to Damon, he saw media reports saying kayaks were in short supply due to the COVID-19 pandemic. That hasn't been the case at Nomad Ventures"We've had the busiest year as far as I can remember in terms of kayaks selling a lot of kayaks here," Damon said. So to say there is a kayak shortage, at least in San Diego, would not be accurate as far as Damon is concerned."Our shutdown was right when we were at complete inventory," Damon said. "Stock levels were high, and when we reopened, we had stock."He was quite alarmed when customers were steered towards shopping online when his shop was completely full of outdoor products. "We have back stock in storage units that we pull from to restock the store. We just picked up a new load of five kayaks, so we are fortunate that we have product," Damon said.His message to customers in the market for a new kayak is quite simple, shop small business and local."We've been in business 40 years, so we felt it was important to get our message out. We are open and we have product," says Damon. 1622

Excessively high or low body mass index measurements have been linked to an increased risk of dying from nearly every major cause except transport accidents, new research says.The?study, published Wednesday in The Lancet Diabetes and Endocrinology and conducted by scientists at London School of Hygiene and Tropical Medicine, revealed that BMI that's either too high or too low is tied to increased morbidity from a range of major diseases.Krishnan Bhaskaran, lead author of the study and associate professor of statistical epidemiology, noted that his team found "important associations" between BMI and most causes of death."BMI is a key indicator of health. We know that BMI is linked to the risk of dying overall, but surprisingly little research has been conducted on the links to deaths from specific causes," he said."We have filled this knowledge gap to help researchers, patients and doctors better understand how underweight and excess weight might be associated with diseases such as cancer, respiratory disease and liver disease."BMI is determined by dividing a person's weight in kilograms by the square of their height in meters.The study authors say they discovered that maintaining a BMI in the range of 21 to 25 kg/m2 is linked to the lowest level of morbidity.BMI outside this range was shown to have a "J-shaped association" with nearly all causes of death, not solely the most prevalent diseases. This means BMIs both lower and higher than the optimal range lead to increased risk of morbidity.The study, which analyzed data from 3.6 million people and 367,512 deaths, showed that obesity, or BMI of 30 or more, was linked to an increased prevalence of two major causes of death: heart disease and cancer."BMI higher than 25, the upper end of healthy, is linked to most cancers, most cardiovascular diseases, respiratory disease, and liver and kidney conditions," Bhaskaran said.Obesity was shown to reduce life expectancy by 4.2 years in men and 3.5 years in women, and it can contribute to other chronic conditions including respiratory disease, liver disease and diabetes.The British Journal of Cancer reported in April that obesity is linked to 7.5% of cancers in UK women.The charity Cancer Research UK estimated that 23,000 women will deal with obesity-related cancers by 2035. Obesity will also become the most common cause of cancer in women by 2043 if trends continue.The study also revealed that being underweight is linked to a "surprising wide range of deaths," including dementia, Alzheimer's, cardiovascular disease and suicide.However, Bhaskaran noted that links between low BMI and causes of death were more "observative," as it was less clear whether low weight was the direct cause of illness or rather a marker of poor health more generally.He also acknowledged the limitations of the study, which included a lack of information on the diet or level of physical activity of the individuals involved and the impact these factors may have had on morbidity.He nevertheless noted that the findings reiterated the importance of maintaining a BMI within the 21 to 25 range. 3130
