As many public health experts have expressed concern over President Donald Trump's re-election rallies amid the coronavirus pandemic, a study conducted by Stanford University examined the number of illnesses stemming from the rallies.According to the study published last week, the rallies likely caused 30,000 other coronavirus-related infections, resulting in 700 deaths. The study's authors noted that these cases were not specifically from rally attendees, which means that attendees could have spread the virus to others.The study did not use contact tracing; instead, they relied on a statistical model that analyzes the virus's spread in communities Trump held rallies.Specifically, researchers examined 18 rallies Trump held from June 20 to Sept. 22, noting that coronavirus cases in the area near the rallies increased by more than 250 per 100,000 residents."Our analysis strongly supports the warnings and recommendations of public health officials concerning the risk of COVID-19 transmission at large group gatherings, particularly when the degree of compliance with guidelines concerning the use of masks and social distancing is low," the study's authors said. "The communities in which Trump rallies took place paid a high price in terms of disease and death."Trump's rallies have generally included thousands of supporters standing shoulder to shoulder. While masks are often handed to supporters, most supporters at rallies opt not to wear them.Public health experts say that a combination of masks and keeping six feet of distance helps minimize the virus's spread, which has claimed more than 230,000 American lives since the spring.Public health experts have also encouraged people to hold gatherings outside, as most Trump rallies since he resumed campaigning in June have been held outdoors with a few exceptions.Trump has often mocked his opponent Joe Biden, who has held much smaller events to spread out the crowd. Biden has held several "drive-in" style events.Dr. Anthony Fauci, whose recent disagreements with Trump have boiled over on the campaign trail, said in an interview with CNN, he was troubled by Trump's rallies."We know that is asking for trouble when you do that," Fauci told. "We've seen that when you have situations of congregate settings where there are a lot of people without masks, the data speak for themselves."To read the full study, click here. 2403

At least two people were injured when an air duct fell from the ceiling at Kalahari Resort in Sandusky, Ohio, according to the Erie County sheriff's office.According to a 911 caller, a 25-foot section of the duct fell into a pool area.Went to kalahari for a fun day with my daughter and now we have to leave bc of the tubes fell pic.twitter.com/2S3j9M33q5— Phil is to sweet (@Philsmarshmalow) March 12, 2018 415

As the pandemic continues, homeless shelters are having to change their approach to meet the needs of families.At least one network of shelters is doing that by trying to prevent homelessness.Family Promise is the largest homeless shelter in the country. Last year, it helped 93,000 people.It provides aid to those who need housing by placing them with community partners within the interfaith community.The executive director in Arizona says the problem right now is these communities are shutting down in the pandemic.“The congregations in the last six months, five and half months, have gotten used to not hosting,” said Ted Taylor, Executive Director of Family Promise Arizona. “We have to get them back into the hosting mode because it is what makes our model work. So, the fear that is at congregations still remains. It is real and it is a very difficult start.”Family Promise says the average cost to rescue a family is ,000 and it takes as long as four months. For Family Promise, it costs ,000 and takes 43 days.While their new effort to prevent homelessness gets up and running, Family Promise says looming evictions require more community support than ever.So far, Family Promise has prevented 10 families from homelessness in Arizona. It hopes to reach 40 by the end of the year.Nationwide, the executive director says the effort to prevent homelessness could reduce the number of people needing a place to stay by 25%. 1445

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

AUSTIN, Texas (AP) — Texas and six other states are suing to end once and for all a program that would protect some young immigrants from deportation.The lawsuit announced Tuesday comes a week after a federal judge in Washington ordered the Trump administration to resume the Deferred Action for Childhood Arrivals program.Immigrants under the Obama-era program are commonly referred to as "Dreamers." Republican Texas Attorney General Ken Paxton had threatened legal action for the past year if the program didn't come to a halt.Joining Texas in the lawsuit are Alabama, Arkansas, Louisiana, Nebraska, South Carolina and West Virginia.A federal judge in Washington called the Department of Homeland Security's rationale against the program "arbitrary and capricious." He gave the Trump administration 90 days to make a new case. 837
