The US stock market sank deeper into the red following sluggish economic reports on Monday and bad news from a couple of blue-chip giants.The Dow fell 600 points by late afternoon, or 2.6%. The S&P 500 lost 2.6% and retreated to its lowest level of the year. And the Nasdaq joined the Dow & S&P 500 in negative territory for 2018. All three indexes have plunged about 7% so far this December.The Dow closed down 507 points for the day.And the Russell 2000 index of small-cap stocks tumbled into a bear market, marking a 20% decline from the record highs notched in late August.A weaker reading from the New York Federal Reserve about manufacturing in the Empire State and a drop in confidence from the nation's homebuilders weighed on the markets."Investors are zeroing in on this idea of slower growth for 2019," said Michael Arone, chief investment strategist at State Street Global Advisors. "More people are worried about a recession in late 2019 or 2020."The political noise in Washington isn't helping either. President Trump, in a tweet Monday morning, repeated his criticism of the Federal Reserve for its recent rate hikes. The Fed meets Wednesday and is widely expected to raise rates again.But Trump tweeted that "it is incredible that with a very strong dollar and virtually no inflation, the outside world blowing up around us, Paris is burning and China way down, the Fed is even considering yet another interest rate hike. Take the Victory!"The Fed is supposed to be politically independent. Any evidence that it might be swayed by attacks from Trump could unnerve the markets."If the Fed doesn't raise rates it will look like it's succumbing to the bullying of Trump's tweets," Arone said.But Nancy Perez, managing director at Boston Private, said the Fed is likely to slow down its pace of rate hikes in 2019 simply because the economy is slowing, not because of pressure from Trump.Perez added that the recent market turmoil is justified because investors are readjusting to this fact."We have been getting a bump in profit margins due to lower taxes but the earnings growth itself is not sustainable," Perez said. "Projections will come down and volatility will continue." 2247

The sky is lovely, dark and deep. But these golfers in Hawaii have rounds to go before they sleep.Stunning photos taken at Hawaii's Big Island on Tuesday show golfers coolly hitting the links even as a monstrous ash plume looms behind them.The eruption of the Kilauea volcano has already destroyed houses, caused evacuations and threatened to wreak havoc on Hawaii's tourism industry. On Tuesday, a plume of ash from the volcano rose 12,000 feet into the air, dropping ash on sections of the island.The US Geological Survey issued a red alert on Tuesday warning of an imminent major eruption.But clearly, not everyone was so worried. 646

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 Trump administration supports reopening schools this fall, in addition to sending 125 million reusable masks to school districts they released new guidance this week for districts to reopen safely.The Schools Should Reopen Safely policy is based on three assumed facts by the administration: that prolonged school closures cause harm, children are at low risk for serious illness from Covid-19, and that educating children is a top national priority.President Trump attended a discussion Wednesday about getting children back to school where the policy was discussed with administration leaders, medical experts and educators. Some of the speakers referenced how the coronavirus pandemic has provided an experiment for virtual learning.“But the virtual learning is not like being in a classroom, and we’ve learned that, I think, very strongly — in almost all cases. People thought for a long time that would be the answer but it’s — that’s not the answer. The answer is an old-fashioned one,” President Trump said.The recommendations encourage the use of masks and social distancing, as well as educating students, teachers and staff about Covid-19 symptoms. They follow guidance released earlier this year from the Centers for Disease Control and Prevention.The document lists eight recommendations for schools:Ensure all students, teachers, and staff understand the symptoms of COVID-19 and its risk factors.Require all students, teachers, and staff to self-assess their health every morning before coming to school; if they are symptomatic they should consult their physician.Encourage frequent handwashing or hand sanitizing during the school day, beginning upon entrance to the school, by ensuring that handwashing facilities are widely available throughout the school.Minimize large indoor group gatherings; hold large gatherings outdoors whenever possible.Maintain high standards of hygiene and ventilation within all classrooms, including keeping windows and doors open and running fans and AC units whenever possible.Require students, teachers, and staff to socially distance around high-risk individuals.Encourage the use of masks when social distancing is not possible.Liberally post instructions regarding hygiene and social distancing around the school.There are also recommendations for high-risk teachers and students, including giving these individuals options to stay home.“Provide high-risk students, or students who have high-risk family members, the choice to stay home and engage in distance learning,” the guidance states.The policy is a set of recommendations and not mandatory for schools to reopen. States and districts are able to make their own decisions. 2694
