REDWOOD CITY, Calif. (AP) — Tech giant Oracle is moving its headquarters from California to Austin, Texas. Oracle announced the move Friday. It's not clear how many Oracle employees will move. The business software maker says it is letting many workers choose their office locations and decide whether to work from home. Oracle's announcement comes just days after Tesla founder Elon Musk announced that he has moved to Austin. RELATED: Tesla seeks to sell B in stock; CEO Musk moves to TexasOracle's decision is a bragging-rights win for Texas, which has been pursuing California companies for years. Texas Governor Greg Abbott is boasting about the Oracle move, saying on Twitter that Texas is the land of business, jobs, and opportunity. 750

Researchers from Florida Atlantic University released a video on Tuesday that shows how droplets disperse into the air from a person’s mouth.The researchers used different kinds of masks to analyze the disbursement of the droplets. The researchers also showed that without a mask, six feet of distance might not be enough to avoid infection.The FAU team tested a single-layer bandana-style covering, a homemade mask that was stitched using two-layers of cotton quilting fabric consisting of 70 threads per inch, and a non-sterile cone-style mask that is available in most pharmacies. The team used a mannequin, Laser lights and synthetic fog to help visualize the spread of the droplet from a cough..The researchers said that stitched quilted cotton masks worked the best in the simulation, with droplets from emulated coughs traveling just 2.5 inches from the mask. By comparison, without a mask, the droplets moved more than 8 feet, with some droplets traveling up to 12 feet during a heavy cough. The researchers also noted that the droplets remained suspended in midair for up to three minutes in the simulated environment.“We found that although the unobstructed turbulent jets were observed to travel up to 12 feet, a large majority of the ejected droplets fell to the ground by this point,” said Dhanak. “Importantly, both the number and concentration of the droplets will decrease with increasing distance, which is the fundamental rationale behind social-distancing.”FAU said that droplets from a cough traveled 3 feet, 7 inches from a bandana; 1 foot, 3 inches from a folded handkerchief; and 8 inches from a cone-style mask.“Preliminary results from our experiment reveal that significant concentrations of small particles from a turbulent jet such as from a heavy cough/sneeze can linger in still air for more than one minute. It only took the particles a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet,” said Siddhartha Verma, an assistant professor in FAU’s Department of Ocean and Mechanical Engineering.Last week, the University of Washington’s Institute for Health Metrics and Evaluation projected that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.Last month, a study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.The CDC issued guidance in April to recommend mask wearing while in public, which has become a requirement to enter retail establishments in more than a dozen states.The CDC's guidance stressed several points: That wearing a face covering is not a substitute for social distancing, and that the public should not use medical or surgical masks. The recommendations suggest the public should use fabric or cloth that covers the mouth and nose.To view FAU's video, click here. Justin Boggs is a writer for the E.W. Scripps National Desk.

President-elect Joe Biden’s favorability rating has risen six percentage points since the election while President Donald Trump’s has slipped three points, according to a recent survey from Gallup.The survey talked to Americans between November 5-19, during a time when the Trump campaign’s legal team was filing lawsuits and challenging the general election results in several states. The results were published after Thanksgiving. The survey asks people if they have a favorable opinion of the person.Biden’s favorability is at 55%, the highest it’s been in the Gallup survey since February 2019 right before he declared his presidential campaign. Trump’s favorability is at 42%, down from 45% right before the November election.The highest favorability rating President Trump has received during his presidency was 49% in April as the country was in the initial stages of the coronavirus pandemic.The post-election results appear to be most impacted by changes in responses from people who identify as Republican. Biden’s favorability among this group grew from 6% to 12% since the election, while Trump’s rating among this group dropped from 95% to 89%.Gallup says Biden’s bump in favorability is in line with trends they have seen after presidential elections since 2000.Meanwhile, ratings for losing presidential candidates in Gallup’s poll have been mixed over the years; John McCain and Mitt Romney saw a higher rating post-election, and Hillary Clinton’s rating was unchanged after the 2016 election. 1517

President Donald Trump tweeted a photo on Wednesday of rockets that were aimed at the US Embassy in Baghdad, and claimed that the rockets were fired by Iran.The attack came on Sunday, embassy officials confirmed. Trump said that three of the rockets failed to launch.The embassy said that there was minor damage to the compound, but no injuries. The US embassy said there were reports of damage and injuries in residential communities near the embassy.“These sorts of attacks on diplomatic facilities are a violation of international law and are a direct assault on the sovereignty of the Iraqi government,” the US Embassy in Baghdad tweeted.“Some friendly health advice to Iran: If one American is killed, I will hold Iran responsible. Think it over,” Trump said on Wednesday.Tensions rose earlier this year between Iran and the US after Iranian General Qasem Soleimani was killed after a US attack on the influential Iranian military leader. Iran responded by firing more than a dozen missiles that struck two airbases in Iraq that houses U.S. troops, the Pentagon confirmed. Iran said at the time that it did not seek to escalate tensions between the two nations."Iran took & concluded proportionate measures in self-defense under Article 51 of UN Charter targeting base from which cowardly armed attack against our citizens & senior officials were launched," Iran's Foreign Minister Javad Zarif said in January. "We do not seek escalation or war, but will defend ourselves against any aggression."Saeed Khatibzadeh, a spokesperson for Iran’s foreign ministry, alleged on Monday that the US was responsible for escalating tensions following Sunday’s attack.“We strongly refute Secretary (Mike) Pompeo 's irresponsible anti-Iran accusations, which blatantly aim to create tension,” Khatibzadeh tweeted. “Iran rejects any attack on diplomatic missions. The U.S. military presence is the source of instability in our region. No amount of spin can divert blame for its evils.” 1991

President-elect Joe Biden and his wife, Dr. Jill Biden, will receive an initial dose of Pfizer's COVID-19 vaccine in their home state of Delaware on Monday according to Reuters and PBS.Vice president-elect Kamala Harris will also receive the vaccine later this month, the outlets report.Biden said earlier this week that he would receive the vaccine "sooner rather than later," adding that he didn't want to "get ahead of the line, but I want to make sure we demonstrate to the American people that it is safe to take."It's not yet clear whether Biden would receive his vaccination in a live TV broadcast, as Vice President Mike Pence did on Friday morning.Three other former presidents — Barack Obama, George W. Bush and Bill Clinton — have all independently agreed to be vaccinated in a public setting to instill confidence in the vaccine's safety to the public.This story is breaking and will be updated. 915
