At Tivoli Brewing Company, canning beer has gone from celebratory to an almost sobering experience.“This sucks,” said Ethan Tsai, Tivoli brewery director.Tsai says Tivoli and other breweries across the country are suffering from an aluminum can shortage.“We don’t have enough cans, we’re not going to be able to sell enough beer,” he said. “This is going to be a financial pinch to a whole lot of people.”On a normal week, Tivoli would turn out almost 400 cases of beer. During the last few of weeks, however, they’re struggling to get out 100.“Sales is going to suffer,” Tsai said. “And if sales suffer, then our ability to survive is going to be jeopardized.”Experts say there are several reasons for this shortage in cans. More people are stocking up on beer in stores and taking it home during the COVID crisis and less customers are going out to bars and restaurants.Whatever the case, production of cans isn’t keeping up with the demand.“For the year 2020,” Tsai said, “Ball (Corporation) is estimating approximately 10 billion, that’s billion with a “B”, aluminum can shortage."Ball Corporation is one of the world’s leading aluminum can providers. It’s responding to the recent surge in demand for cans by expanding its operations and building two news production plants which they say should be completed by 2021.“It might mean that some brewers get less revenue and have to make more difficult choices,” said Bart Watson, chief economist with the Brewers Association, an organization representing thousands of craft breweries across the country.He says cans make up a majority of craft beer packaged sales and that this shortage of could cost companies money and employees their jobs.“It’s tough to see the small brewers, who put so much sweat equity into their businesses, be brought down by really something that not their fault,” Watson said. “First the pandemic and now these additional challenges like a shortage.”Back at the brewery, Tsai is trying to figure out how to logistically juggle this shortage of cans during a pandemic to make sure his staff still have jobs and that this brewery survives.“We are all in this together,” he said. “None of us benefit from just taprooms suddenly disappearing.” 2226

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

  

ATLANTA (AP) — Authorities are offering a ,000 reward as they continue to search for the person who shot actor Thomas Jefferson Byrd in Atlanta. Byrd was known best for his roles in Spike Lee films. He was found dead around 1:45 a.m. Saturday on the city's southwest side and had been shot multiple times in the back.The reward was announced Tuesday. Police have not identified a suspect in the 70-year-old actor's shooting death or said why he was killed. Byrd acted in films including "Clockers," "Chi-Raq," "Bamboozled," "He Got Game" and "Da Sweet Blood of Jesus." 579

  

As the world sputters amid a global coronavirus pandemic that may have originated from bats in China, researchers released a study on Monday indicating that pigs could transmit a pandemic-level flu strain to humans.The Chinese and British based researchers, who published their findings in the Proceedings of the National Academy of Sciences on Monday, said that G4 EA H1N1 viruses in pigs should be closely monitored in human populations, especially among workers in the swine industry.The researchers said that pigs are intermediate hosts for the strain of influenza, which researchers are concerned could spread to humans. A further concern is that humans could spread the virus to other humans, prompting a pandemic. While the study notes that the virus had spread to workers in the swine industry, it likely has not been transmitted from humans to humans.“G4 viruses have all the essential hallmarks of a candidate pandemic virus,” the team of UK researchers wrote.The researchers said G4 viruses bind to human-type receptors, produce much higher progeny virus in human airway epithelial cells, and show efficient infectivity and aerosol transmission in ferrets.While the study indicates cause for some concern, Martha Nelson, an evolutionary biologist at the U.S. National Institutes of Health’s Fogarty International Center, told Science Magazine the chances of a pandemic from G4 viruses are “low,” but added that no one knew the pandemic risk of H1N1 until 2009.“Influenza can surprise us,” Nelson told Science. “And there’s a risk that we neglect influenza and other threats at this time” of COVID-19.Nelson added to Science that given the warning, it would be ideal to produce a human G4 vaccine as the world still needs to be vigilant on other pandemics besides COVID-19.Domestically, the University of Missouri reviewed the research. 1855
