Mjeu Iowa hero saves couple from oncoming train
Right from the start there s been no doubt Nathaniel Brazill shot and killed hi stanley uk (https://www.stanley-cups.co.uk) s teacher. In a Florida courtroom, witness after witness has testified against him, from teachers to classmates, reports CBS News Correspondent Bobbi Harley.And the actual crime was sh stanley quencher (https://www.cups-stanley.co.uk) own on a big screen in court Thursday. Frame by grainy frame, jurors watched 75 seconds of what a surveillance camera caught: a then 13- stanley ca (https://www.stanleymugs.ca) year-old Brazill in his school s hallway, raising a gun and firing, fatally shooting his middle school teacher, then running away. But not before raising the gun again and pointing it at John James, another teacher at Lake Worth Middle school. I saw what he had in his hand 151; a little hand gun, testified James.The key piece of evidence was played at the first-degree murder trial of Nathaniel Brazill, now 14. He is being tried as an adult and faces life in prison without parole if convicted. The defense contends the gun went off accidentally.Grant Frederick, a video specialist hired by prosecutors, took the jury through each frame of the tape, which shows Brazill arriving by bicycle at the school and then standing outside the classroom of English teacher Barry Grunow.He said the seventh-grader thrust both hands in front of him - he called it a shooter s stance - just before Grunow collapsed to the floor.Frederick said Brazill stood outside the classroom for 20 seconds and held both hands, apparently pointing a gun at Grunow, for four seconds before running down a hall.

Its hard to let go of some memories, even if your head has been chopped off. Well, at least if youre a flatw stanley water bottle (https://www.cup-stanley.uk) orm. When these tiny critters are decapitated, their heads and brain ev stanley cup (https://www.cup-stanley.co.uk) entually grow back. But more remarkable than that, so too do their previous memories. Scientist who study planarian flatworms have known for quite some time that these organisms can regenerate their entire body, includ stanley fr (https://www.stanley-cups.fr) ing the brain. They also know that these worms are capable of storing long-term memory, which, for these little guys, translates to about two weeks. And work done in the 1960s suggested that certain memories might come back after regeneration, but the results were clunky and inconclusive. Working with more advanced techniques i.e. computerized tracking , biologists Tal Shomrat and Michael Levin got to thinking: What would happen to a flatworm that was trained on a specific task, and then had its head chopped off Would its memory of the learned behavior also regenerate Conveniently, it takes less than 14 days for the flatworm to regenerate its new brain, which is the maximum length of time for its long-term memory to persist. So, to embed a specific memory, the researchers spent 10 days teaching the flatworms that food could be found at the center of a petri dish with a light shining on it. This was particularly challenging for the worms because they like to hang out at the peripheries of petri dishes and they have an aversion to light. But, given enough positive association, they
