As screen time becomes a bigger part of students’ lives, preserving their vision is something to keep an eye on.Dr. Lauren Schneider, an ophthalmologist who has been treating patients in New York and Connecticut for six years warned screen time can cause a number of symptoms, including squinting and eye-crossing.“We do know that prolonged near work can place some children at risk for progressive myopia, which is worsening nearsightedness,” Dr. Schneider said.Doctors say tips on preserving your kids' vision during remote learning include making sure they keep a safe distance from their devices — at least 15 inches away from the screen is recommended — having them take screen breaks every 20 minutes and investing in a blue light blocker, which can be put on devices or glasses.“Some of our data suggests blue light emitted from our electronic devices may potentially be harmful long term to the center of the retina,” said Schneider Sunday.As school districts in the tri-state area continue to reopen this fall with full remote or hybrid learning models that include screen-based instruction, eye protection is another safety measure doctors say parents should have their sights on.“We want to make sure that while our students are hard at work which is going to require a lot of time in front of the computer that we’re avoiding unnecessary eye strain," Schneider said.According to medical experts, the full long term impacts on the eyes from remote learning are still being looked at, regular eye exams are highly recommended.For more tips and resources:www.visiontolearn.orgwww.childrenseyefoundation.orgwww.kidshealth.orgThis story was first reported by Jennifer Bisram at PIX11 in New York City, New York. 1726

As people prepare to travel for Christmas, experts are concerned about another spike in coronavirus cases.We are almost a month out from Thanksgiving, and according to the COVID Tracking Project, more than 47,000 people in the U.S. have died from COVID-19 since Thanksgiving.And although the CDC advised against traveling, the Transportation Security Administration screened 9.5 million travelers during the 10-day Thanksgiving travel period.TSA also screened more than 3.2 million people at airports nationwide this past weekend.And as people gear up to spend the Christmas holiday with loved ones, the surge of new COVID-19 cases continues with no end in sight.The Harvard Global Health Institute and Brown School of Public Health created a risk-assessment tool that color-codes states with over 25 new daily cases per 100,000 people. The color red on the map means the state is considered "at a tipping point."According to the Harvard and Brown researchers, the 10 worst states considered to be "at a tipping point" are Tennessee, Rhode Island, California, Alabama, Arizona, Oklahoma, Indiana, Utah, Arkansas, and Delaware.According to Johns Hopkins University data, in Tennessee, the state's positive rate is 19.2%.In Alabama, the state's positive rate is 40.4%. Arkansas's positive rate is 18.7%, Arizona's is 13.1%, Delaware's is 7.7%, 13.3% of COVID tests in California are positive, Oklahoma's positive rate is 21.1%, Indiana has an 11.6% positive rate, Rhode Island is at a 6.3%, and 17.6% of COVID tests in Utah are positive.According to the CDC, between 1.2 million to 2.3 million new cases are likely to be reported in the week ending January 9, 2021. 1671

At least 36 people have been confirmed dead as a result of Hurricane Michael, according to authorities.The number rose Saturday after a local medical examiner confirmed the death of a woman in Bay County, Florida, bringing the death toll in Florida alone to 26.Authorities did not offer additional details on the death. 327

At 3 p.m. ET on Monday, November 26, a group of researchers will be really sweating. The NASA InSight spacecraft will try to land on Mars.After six months of flight, the lander component of the probe will detach itself from the cruise stage and head into the atmosphere. The lander component initially looks a fair bit like the re-entry capsule used in the 1960s and 1970s for the Apollo moon missions -- sort of conical, with a smooth and flat bottom. That bottom is a crucial heat shield that is designed to protect the probe as it passes through the thin Martian atmosphere.The landing is a devilishly difficult feat. The landing capsule has to batter its way through the atmosphere. It will fly through the Martian air at an initial speed of 12,300 mph, and it must hit the atmosphere at an angle of precisely 12 degrees. Any shallower, and the probe will bounce off into deep space. Any steeper, and the probe will burn itself up in a spectacular and fiery death. The probe will first touch the atmosphere six minutes and 45 seconds before landing. During this phase, it will experience acceleration 12 times that of the Earth's gravity. Were the probe a 150-pound human, during the flaming descent, it would weigh nearly a ton.About 3? minutes after the probe hits the atmosphere, a parachute will deploy, slowing down the probe even more. Fifteen seconds later, explosives will blow the heat shield off, exposing the actual InSight probe hidden inside. Ten seconds after the heat shield falls away, the probe will extend its legs, much like an airplane extends its wheels before touching down.The probe will fall for an additional two minutes attached to the parachute and protected by its conical shell. About 45 seconds before InSight lands, it will drop out of the shell and fall toward the surface. As soon as it leaves the shell, its landing rockets will ignite.The actual InSight probe looks a little bit like the Apollo moon lander, with three legs to support it and a boxy top. The rockets will slow it further and stop any remaining horizontal motion. Then, about 15 seconds before touchdown, the InSight probe will descend at a speed of 8 feet per second, before hopefully touching down gently on the Martian surface.The entire landing sequence will take about seven minutes to occur. A radio signal from Mars to Earth currently takes about eight minutes and seven seconds to get here. So the complete landing process will take place before we find out if it was successful. It will be done automatically, entirely by the probe itself. For the scientists and engineers who designed InSight, this is called "seven minutes of terror."And they are right to be worried. Mars is a graveyard of failed probes. There have been 44 attempts by various national space agencies to land on Mars. Eighteen have been successful. Twenty-three have not. Three have achieved orbit but failed at a landing.So, what does InSight hope to achieve? Well, as it happens, a lot. But it's different than the intrepid Curiosity probe, which NASA landed in 2012. InSight will not move around. Instead, it will stay put and tell us of the interior of Mars.One thing it will do is emit radio waves that we can monitor on Earth. By making careful measurements of how the frequency of the radio waves change, we will be able to measure the degree to which Mars wobbles as it rotates. That will tell us something about the core of the planet, specifically its makeup and information on the degree to which it is molten.InSight will also deploy a seismometer to listen for marsquakes (like earthquakes, but Martian-style) and for impacts of meteors on the planet. Information gleaned from the waves the seismometer detects will tell us more about the planet's interior.The third thing InSight will do is to dig below the planet's surface. Using a jackhammer, the probe will drill down 5 meters (16 feet) into the planet and, basically, it will take the planet's temperature.There are many reasons this is interesting. Taking the temperature at that depth will allow planetary scientists to determine how much heat is escaping from Mars. More broadly, this measurement will allow a clear determination of the temperature of the planet much closer to the core.This information will tell us a lot about how Mars formed, which, in turn, will add to the information of how rocky planets, including our own Earth, typically develop.And if you're more of an explorer kind of person and not so interested in Martian geology, it will also tell us how warm the planet is at modest depths, which will tell us if there is any chance of liquid water on the planet. Perhaps obviously, if the Martian subsurface is warm enough, any buried water will be in liquid form and not ice. Finding liquid water would be the key discovery that would make Martian exploration relatively easy. A relatively recent possible discovery of a buried Martian lake was promising, but the data was not conclusive. Knowing that the ground is warm would be very comforting to possible future explorers.Exploring the solar system is the first step toward exploring the stars. The InSight probe will give us --well -- insight into whether this is something that humanity will achieve in the foreseeable future.And maybe Elon Musk's bet on him getting to Mars will become true. 5329

Australian scientists are searching for the remnants of a meteor which burned spectacularly across the sky in Perth Tuesday night.The unusual phenomenon was caught on camera by multiple spectators, and described as a "fireball" on social media.Curtin University professor Phil Bland told CNN it was "almost certainly" a chunk of asteroid coming through the atmosphere, an event which he said occurs only a couple of times a year. 437
