As the pictures come in from along the Florida panhandle, especially from devastated Panama City and Mexico Beach, many of us are feeling a need to help those who lost their homes. Should you give cash, donate cleaning supplies or collect canned goods?Giving is good. But giving to a good charity — one that knows how to get the help to victims quickly — is even better.The Better Business Bureau and Charity Navigator are offering advice on how to donate and sharing which groups are best prepared to distribute your donation.Despite all the new high tech ways to donate, from crowdsourcing to charity apps, an oldie might be your best bet at first. 663

Attorney General Jeff Sessions fired former FBI Deputy Director Andrew McCabe late Friday, less than two days shy of his retirement, ending the career of an official who had risen to serve as second-in-command at the bureau.McCabe had more recently been regularly taunted by President Donald Trump and besieged by accusations that he had misled internal investigators at the Justice Department.McCabe had been expected to retire this Sunday, on his 50th birthday, when he would have become eligible to receive early retirement benefits.But Friday's termination could place a portion of his anticipated pension, earned after more than two decades of service, in significant jeopardy.The origin of his dramatic fall stems from an internal review conducted by Justice Department Inspector General Michael Horowitz. That report -- the details of which have not been publicly released -- is said to conclude that McCabe misled investigators about his role in directing other officials at the FBI to speak to The Wall Street Journal about his involvement in a public corruption investigation into the Clinton Foundation, according to a source briefed on it. 1159

As the debate over arming teachers in schools reverberates across the country, Kansas is doubling down on the idea.A new bill would not only authorize the arming of Kansas school staff, it would hold schools responsible if a shooting were to occur and the teachers and staff present were not allowed to be armed.Here's the exact wording?from House Bill 2789:"In any action against a unified school district arising out of acts or omissions regarding the possession or use of firearms on the premises of such school district, there shall be a rebuttable presumption of negligence on the part of such school district when it is shown by evidence that such school district did not authorize any employee of such school district, other than school security officers, to carry concealed handguns..."The House bill is causing some serious contention in the Kansas state capitol. During a House Insurance Committee hearing on Tuesday, Rep. Blake Carpenter, one of the bill's authors, quoted the movie "American Sniper" and said violence in school was a matter of "when" and not "if.""It's not if our kids will be killed; it is when they will be killed and what we are doing to prevent it," he said,?according to the Kansas City Star.CNN has reached out to Carpenter for comment.The bill has received significant pushback. A group of protesters was present at Tuesday's hearing, and Rep. Brett Parker, a Democratic opponent of the bill, shared a photo of stacks of papers he says are written testimonies against it.Kansas teachers?are technically already allowed by state law to carry guns on public school campuses as long as they have a permit and meet any school-specific requirements. But according to the Kansas City Star the 2013 legislation caused problems with insurance providers for some of the state's school districts, who refused to extend coverage because of the liability of armed staff.As a result, some districts put their own policies in place, overriding the law and disallowing the concealed carry of weapons on school property.The bill currently before the House committee also addresses this by forbidding insurance companies from refusing coverage just because a school district allows teachers and staff to be armed."No insurance company shall charge unfair discriminatory premiums, policy fees or rates for, or refuse to provide, any policy or contract of real or personal property insurance, liability insurance or policy containing liability coverage for any unified school district solely because such school district authorizes employees of such school district to carry concealed handguns on the premises of schools and attendance centers operated by such school district..." the bill states. 2742

As the debate about mask mandates continues in some states, a new study reportedly shows social distancing is just as important to reduce the spread of COVID-19. The study looked at the effectiveness of face coverings when someone coughs repeatedly, coughing is one of the symptoms of COVID-19.The study was published in a June issue of “Physics of Fluid”, by AIP Publishing, and was conducted by Talib Dbouk and Dimitris Drikakis from the University of Nicosia in Cyprus.The researchers used computer modeling to show the range of saliva droplets when people cough. Previous work from this group showed saliva can travel about 18 feet when a person coughs and is not wearing a mask or covering their mouth.This new study built on that research to add in the variables of face coverings and repeated coughing. They used information available about filters used in surgical masks. 887

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
