ABC News(DALLAS) — A Dallas police officer has died after he was shot in the line of duty Tuesday afternoon, officials said Wednesday.A second Dallas police officer and a Home Depot employee were also shot during the attack. The suspect, 29-year-old Armando Juarez, and a woman were arrested hours later following a police chase.“It sobers us to realize what officers walk into day in and day out, and how quickly they can become victims,” Dallas Mayor Mike Rawlings said Tuesday.Nearly two years ago, a sniper gunned down five law enforcement officers in Dallas. That shooting in July 2016 was the deadliest day for United States law enforcement since 9/11.This story is developing. Please check back for more updates.Copyright © 2018, ABC Radio.

Health chiefs have come under fire for launching a consultation on advertising of foods high in fat, sugar or salt (HFSS) while the industry faces Brexit.Views are being sought on the introduction of further restrictions on advertising HFSS foods, including the potential for a 9pm watershed ban on advertising around TV programmes, online streaming sites and social media.Launching the consultation, the Department of Health and Social Care (DHSC) and the Department for Digital, Culture, Media & Sport said ads for sugary and fatty foods were more commonly shown to children than any other category.“Today the government has set out options to tighten advertising restrictions to limit children’s exposure to unhealthy foods across the media they engage with the most,” they stated.But the timing of the consultation has been attacked by the Food and Drink Federation (FDF), which has previously criticised the DHSC for launching a consultation on promotions while food businesses faced uncertainty over Brexit.“Again, this suggests the Department of Health and Social Care has failed to notice the UK is still not out of the Brexit logjam, nor that food and drink companies are battling to ensure the nation is fed,” said FDF chief operating officer Tim Rycroft.He added that the consultation was addressing important matters, but should have been delayed until a no-deal Brexit was completely out of the question, and that the FDF would not be responding to the consultation unless there was a “material change to Brexit prospects”. “Until a delay to the 29 March withdrawal date is agreed by the UK and EU, and Parliament removes that date from the Withdrawal Act, manufacturers will have a total focus on averting the catastrophe of a no-deal Brexit, avoiding food shortages and keeping prices rises to a minimum,” he said.
Nearly a century after it was theorized, Harvard scientists report they have succeeded in creating the rarest material on the planet, which could eventually develop into one of its most valuable.Thomas D. Cabot Professor of the Natural Sciences Isaac Silvera and postdoctoral fellow Ranga Dias have long sought the material, called atomic metallic hydrogen. In addition to helping scientists answer some fundamental questions about the nature of matter, the material is theorized to have a wide range of applications, including as a room-temperature superconductor. Their research is described in a paper published today in Science.“This is the Holy Grail of high-pressure physics,” Silvera said of the quest to find the material. “It’s the first-ever sample of metallic hydrogen on Earth, so when you’re looking at it, you’re looking at something that’s never existed before.”In their experiments, Silvera and Dias squeezed a tiny hydrogen sample at 495 gigapascal (GPa), or more than 71.7 million pounds per square inch, which is greater than the pressure at the center of the Earth. At such extreme pressures, Silvera explained, solid molecular hydrogen, which consists of molecules on the lattice sites of the solid, breaks down, and the tightly bound molecules dissociate to transforms into atomic hydrogen, which is a metal.While the work creates an important window into understanding the general properties of hydrogen, it also offers tantalizing hints at potentially revolutionary new materials.“One prediction that’s very important is metallic hydrogen is predicted to be meta-stable,” Silvera said. “That means if you take the pressure off, it will stay metallic, similar to the way diamonds form from graphite under intense heat and pressure, but remain diamonds when that pressure and heat are removed.”Understanding whether the material is stable is important, Silvera said, because predictions suggest metallic hydrogen could act as a superconductor at room temperatures.“As much as 15 percent of energy is lost to dissipation during transmission,” he said, “so if you could make wires from this material and use them in the electrical grid, it could change that story.”A room temperature superconductor, Dias said, could change our transportation system, making magnetic levitation of high-speed trains possible, as well as making electric cars more efficient and improving the performance of many electronic devices. The material could also provide major improvements in energy production and storage. Because superconductors have zero resistance, superconducting coils could be used to store excess energy, which could then be used whenever it is needed.Metallic hydrogen could also play a key role in helping humans explore the far reaches of space, as a more powerful rocket propellant.Microscopic images of the stages in the creation of atomic molecular hydrogen: Transparent molecular hydrogen (left) at about 200 GPa, which is converted into black molecular hydrogen, and finally reflective atomic metallic hydrogen at 495 GPa. Courtesy of Isaac Silvera“It takes a tremendous amount of energy to make metallic hydrogen,” Silvera explained. “And if you convert it back to molecular hydrogen, all that energy is released, so that would make it the most powerful rocket propellant known to man, and could revolutionize rocketry.”The most powerful fuels in use today are characterized by a “specific impulse” (a measure, in seconds, of how fast a propellant is fired from the back of a rocket) of 450 seconds. The specific impulse for metallic hydrogen, by comparison, is theorized to be 1,700 seconds.“That would easily allow you to explore the outer planets,” Silvera said. “We would be able to put rockets into orbit with only one stage, versus two, and could send up larger payloads, so it could be very important.”In their experiments, Silvera and Dias turned to one of the hardest materials on Earth, diamond. But rather than natural diamond, Silvera and Dias used two small pieces of carefully polished synthetic diamond and treated them to make them even tougher. Then they mounted them opposite each other in a device known as a diamond anvil cell.“Diamonds are polished with diamond powder, and that can gouge out carbon from the surface,” Silvera said. “When we looked at the diamond using atomic force microscopy, we found defects, which could cause it to weaken and break.”The solution, he said, was to use a reactive ion etching process to shave a tiny layer — just five microns thick, or about a tenth the thickness of a human hair — from the diamond’s surface. The diamond was then coated with a thin layer of alumina to prevent the hydrogen from diffusing into the crystal structure and embrittling it.After more than four decades of work on metallic hydrogen, and nearly a century after it was first theorized, it was thrilling to see the results, Silvera said.“It was really exciting,” he said. “Ranga was running the experiment, and we thought we might get there, but when he called me and said, ‘The sample is shining,’ I went running down there, and it was metallic hydrogen.”“I immediately said we have to make the measurements to confirm it, so we rearranged the lab … and that’s what we did.”SaveSaveSave
A patient is brought by ambulance to the Maimonides Medical Center in Brooklyn, May 4, 2020. In New York City, the daily onslaught of death from the coronavirus has dropped to half of what it was, much of the country remains in the firm grip of a pandemic with little hope of release. THE NEW YORK TIMES At least 18,011,763 cases have now been registered as the pandemic’s rate of infection continues to accelerate. More than half of them were recorded in the United States and in Latin America and the Caribbean region. PARIS – The number of coronavirus cases recorded worldwide has passed 18 million, according to an AFP tally from official sources at 2240 GMT Sunday (6:40 a.m. Monday in Manila). The United States is the worst-hit country with 4,657,693 cases including 154,793 deaths, followed by Brazil with 2,733,677 cases and 94,104 deaths. The third worst-hit country is India, with 1,750,723 cases and 37,364 deaths. (AFP)
Only you as a parent can decide what type of school is best for your children. Whichever you choose should be one that offers your child the best possible education. Neither type of school has a corner on this solution. Either could be the best choice for your child. That is not what this article is about. Many of the state associations are coming under increased pressure to separate public from private in tournament play. Indiana has not faced as much pressure as some of our surrounding states because we have a rather liberal open-enrollment policy. States that do not allow public school students to transfer have many school personnel that believe parochial schools have unlimited recruiting possibilities, and thus, have unfair advantage when state tournaments begin. They want a separate state tourney format. I am not an advocate of this. I believe Indiana has the best possible solution. What Indiana has done is to legislate that any school who wins consecutive championships in the same sport must move to a higher classification. This means that any school, public or private, who starts dominating a division, must automatically move up. This has kept the IHSAA from being pressured into having separate state tournaments.
Even though it took being on the right end of a tie-breaker to get itself into the Section III Class AA playoffs, the Baldwinsville football team did not waste the opportunity given to them.In fact, when the 2-5 Bees traveled to 5-2 Corcoran for Friday night’s opening-round game, it put together its finest all-around effort of the season, smothering the Cougars on defense and producing points, too, on the way to a 28-3 victory.Not only had B’ville lost three consecutive games entering the sectional playoffs, its defense, still trying to adjust following the season-ending injury to linebacker Mike Letizia, had allowed 111 points to Utica Proctor, Cicero-North Syracuse and Fayetteville-Manlius.But the defense didn’t have to be on the field right away. The Bees’ ground game worked well in its opening drive against Corcoran’s defense, moving to the Cougars’ five before Willie Strong found the end zone.Just as important was Braden McCard intercepting Corcoran quarterback Aidan Murphy at midfield seconds after Strong’s touchdown. With a short field, B’ville moved to the Cougars’ 10 and strong scored again, followed by a two-point conversion.It was easier for the Bees’ defense to operate with a 15-0 lead. Though it fumbled near the goal line early in the second quarter and didn’t score the rest of the half, B’ville’s defense continued to contain the Cougars, only allowing a field goal.The third quarter was scoreless, too, Corcoran’s best opportunity thwarted when Pat May intercepted Murphy at the Bees’ 20, and with all of the empty possessions the Cougars were piling up, B’ville could afford to keep the ball on the ground.Strong got his third touchdown of the night from 15 yards out with 7:53 to play, and when the Cougars crowded the line of scrimmage on the Bees’ next possession, McCard threw deep and found May for a 50-yard scoring pass to seal it.Of the Bees’ 266 yards on the ground, Strong had 137 of them, on 27 carries. Balancing that out, McCard completed 10 of the 12 passes he threw for 152 yards, with May catching five of those passes for 88 yards.To lead that B’ville defense, May made eight solo tackles and got a pair of interceptions. Sophomore Dan Ewald got seven tackles, while Colton Lacey had four tackles and Strong recovered a fumble.A day later, Utica Proctor rolled past Christian Brothers Academy 39-12, setting up next Saturday’s sectional semifinal at 5 p.m. at Vernon-Verona-Sherrill between the Raiders and B’ville, a rematch of the Oct. 4 game that Proctor won 34-17.Now, the Bees and Raiders would determine who would get Liverpool or Cicero-North Syracuse in the Nov. 9 sectional title game at the Dome. Ironically, the showdown between the Warriors and Northstars will take place Saturday at Pelcher-Arcaro Stadium.Share this:FacebookTwitterLinkedInRedditComment on this Story Tags: Baldwinsvillefootball
