As the opioid crisis continues to damage communities across the country, new mapping technology is helping family members of victims cope by allowing them to crowdsource an interactive memorial.The "Celebrating Lost Loved Ones" map, created a couple of months ago, now marks the lives of thousands people lost to opioids. The map was created by engineer Jeremiah Lindemann and allows users to add photos and short stories of loved ones who have passed away, including the place of their passing.The goal of the map is to create a place to honor and respect overdose victims across the United States."(We want a map) that emphasizes the human toll behind the opioid crisis with a visual record of the victims it is leaving behind," Lindemann said. 764

Authorities have now found two packages addressed to former Vice President Joe Biden that are similar in appearance and contain potential explosive devices that resemble the others sent earlier this week to prominent critics of President Donald Trump and CNN, a law enforcement official said Thursday.The two packages, discovered at Delaware postal facilities, were removed late Thursday morning, law enforcement officials said.Earlier Thursday, a suspicious package addressed to actor-director Robert De Niro was reported at the Manhattan building where his production company is based, and its marking and contents appear similar to the other pipe bomb packages, two law enforcement sources said.The FBI said Thursday morning that the three packages are "similar in appearance to the others."A manhunt is underway for the perpetrator behind the packages. Law enforcement authorities are treating the series of bombs as a domestic terror matter and are advising the public to remain vigilant.The motive is unknown, but the recipients are all prominent targets of right-wing criticism and, in many cases, of Trump himself. The package found at CNN's New York bureau in the Time Warner Center was addressed to former CIA Director John Brennan, city and local law enforcement officials said.Devices sent to former President Barack Obama, Hillary Clinton, former Attorney General Eric Holder, California Democratic Rep. Maxine Waters and Democratic donor George Soros showed the presence of a sulfur substance, which could have exploded, a law enforcement official said.The devices are believed to be pipe bombs, inherently unstable, and at risk of being set off just by handling.The FBI's counterterrorism division is leading the investigation Thursday into the packages and the agency says it's possible additional packages were mailed to other locations.At the White House, Trump vowed Wednesday that "we will spare no resources or expense" to pursue the perpetrator. 1975

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

  

ASHEVILLE, North Carolina (WLOS) —Police have identified their suspect after a standoff put multiple establishments near the well-known Biltmore Estate on lockdown Wednesday morning.Asheville Police say they entered a foot pursuit with Gary Adrian Church, 42, of Ronda, N.C., at approximately 9:34 a.m. local time. Church had open warrants for several robberies in Asheville, as well as Burke and Iredell Counties.The suspect fled on foot and into the woods behind the DoubleTree Hotel and TGIFriday’s in Biltmore Village.As a safety precaution, several businesses in the area, including MAHEC, DoubleTree Hotel, TGIFriday’s and the Hampton Inn were all placed on lockdown.The Asheville Police Department’s Crisis Negotiation Team responded to the area and stayed in constant communication with Church. After approximately 3 hours, the suspect was taken into custody with no further incident.No injuries were sustained by officers or the suspect.Police say rumors of an active shooter that had been circulating on social media were incorrect. 1055

  

As we head into cold and flu season, you can expect things will be handled differently at workplaces, schools, day cares and medical offices because of COVID-19.Anyone with symptoms like a runny nose, a cough or sneezing will likely be asked to stay home.“So, I think there's going to be a requirement for any of these symptoms for employee health at the workplace to take a larger role in screening patients probably a lot more testing,” said Dr. Scott Joy, Chief Medical Officer at Englewood Primary Care.Joy spoke with us about how people should handle these symptoms during the COVID-19 pandemic. He recommends staying home for 24 hours when you have a cold without a fever.If you have a fever, isolate for up to six days or until you've been fever free for a full 24 hours. If you're coughing or sneezing more than four times in an hour, you should probably stay home and see a doctor.“We haven't had a metric like that before, so we're going to experiment with that data point and see what it does to our workforce and our clinic infection control over this season,” said Joy.Joy also reminds people to get the flu shot.A study in the New England Journal of Medicine found people who got the vaccine had 25% fewer episodes of upper respiratory infections than those who didn't. That means fewer sick days from work and fewer doctor visits.The hope is that COVID-19 measures like handwashing, mask wearing and watching your distance will lead to fewer respiratory infections overall. But should you experience those symptoms, you may be directed to urgent care centers instead.The idea is to keep doctor offices sterile, so people with chronic conditions and other issues feel safe coming in to see their primary care physician.“In the last couple of months, people that have been putting off their care, I just diagnosed a gentleman, new diagnosis with pancreatic cancer,” said Joy. “We're detecting breast cancer, heart disease blood pressure that is out of control.”Urgent care centers are equipped with personal protective equipment and are typically faster, and cheaper than a visit to a hospital emergency room. But you should call your doctor's office first to see what they recommend based on your symptoms. 2228
