About an hour north of Tampa, Florida is a plain field, surrounded by a fence. It may look like ordinary land, but the fenced-in area is a burial lot for bodies donated in the name of science.The area is known as a body farm, an outdoor research facility where scientists study how a body decomposes in hopes to use that research to better solve crimes.Erin Kimmerle, an associate processor at the University of South Florida, is in charge of the body farm in Land O’ Lakes, Florida.  Kimmerle and her team study the donated bodies to learn more on how bodies break down, both under the sun and underground.Abigail Kenney's husband, who was killed in a car crash, was the first body to be buried at the farm. For her, the place brings her comfort.“I know I might not be the norm, but I have been given such comfort and how everything happened," Kenney says of the research farm.By donating his body, Kenney says she feels her husband, who was a school principal, is continuing to be an educator even after his death.Thanks to the donated bodies, Kimmerle and her team have found just how fast temperature and humidity speed up decomposition. What takes years in a dry air climate can take weeks in areas like Florida.Researchers learn a valuable lesson about scavengers--how drastically they move bodies, something that could be key to a criminal investigation."The vultures will completely turn a body 180 degrees, separate the arms and legs into a sort of spread position, Kimmerle explains."It might look like somebody was dumped there in a haphazard way or maybe staged even."Kimmerle says she discovered a heavy bird sitting on a rib cage can even break bones and collapse a chest cavity.“The number of injuries can speak to how heinous and atrocious the crime is considered to be, which will determine whether or not it becomes a death penalty case," Kimmerle says.Kimmerle’s team recently solved a murder case. By using what they learned about how bodies decompose, they created a facial reconstruction image. Someone was able to recognize the victim as a woman named Jane Weaver. It was later determined Weaver’s boyfriend had fatally shot her before dumping her body."I mean, our lab has done over 350 cases for law enforcement," Kimmerle says.The Florida body farm is one of eight around the country. Each farm studies different climates--from high in the arid climate of western Colorado to strong humid heat in Florida—in hopes of helping to solve crimes and bring families closure."We have the strong belief that for every missing person, there's a family missing them,” Kimmerle says.And for Kenney, it's comforting to know there's more than her husband's memory that is living on."He's had so much impact on other people beyond his death," she says. 2777

After almost two years circling an ancient asteroid hundreds of millions of miles away, a NASA spacecraft this week will attempt to descend to the treacherous, boulder-packed surface and snatch a handful of rubble.The drama unfolds Tuesday as the U.S. takes its first crack at collecting asteroid samples for return to Earth, a feat accomplished so far only by Japan.Brimming with names inspired by Egyptian mythology, the Osiris-Rex mission is looking to bring back at least 2 ounces (60 grams) worth of asteroid Bennu, the biggest otherworldly haul from beyond the moon.The van-sized spacecraft is aiming for the relatively flat middle of a tennis court-sized crater named Nightingale — a spot comparable to a few parking places here on Earth. Boulders as big as buildings loom over the targeted touchdown zone.“So for some perspective, the next time you park your car in front of your house or in front of a coffee shop and walk inside, think about the challenge of navigating Osiris-Rex into one of these spots from 200 million miles away,” said NASA’s deputy project manager Mike Moreau.Once it drops out of its half-mile-high (0.75 kilometer-high) orbit around Bennu, the spacecraft will take a deliberate four hours to make it all the way down, to just above the surface.Then the action cranks up when Osiris-Rex’s 11-foot (3.4-meter) arm reaches out and touches Bennu. Contact should last five to 10 seconds, just long enough to shoot out pressurized nitrogen gas and suck up the churned dirt and gravel. Programmed in advance, the spacecraft will operate autonomously during the unprecedented touch-and-go maneuver. With an 18-minute lag in radio communication each way, ground controllers for spacecraft builder Lockheed Martin near Denver can’t intervene.If the first attempt doesn’t work, Osiris-Rex can try again. Any collected samples won’t reach Earth until 2023.While NASA has brought back comet dust and solar wind particles, it’s never attempted to sample one of the nearly 1 million known asteroids lurking in our solar system until now. Japan, meanwhile, expects to get samples from asteroid Ryugu in December — in the milligrams at most — 10 years after bringing back specks from asteroid Itokawa.Bennu is an asteroid picker’s paradise.The big, black, roundish, carbon-rich space rock — taller than New York’s Empire State Building — was around when our solar system was forming 4.5 billion years ago. Scientists consider it a time capsule full of pristine building blocks that could help explain how life formed on Earth and possibly elsewhere.“This is all about understanding our origins,” said the mission’s principal scientist, Dante Lauretta of the University of Arizona.There also are selfish reasons for getting to know Bennu better.The solar-orbiting asteroid, which swings by Earth every six years, could take aim at us late in the next century. NASA puts the odds of an impact at 1-in-2,700. The more scientists know about potentially menacing asteroids like Bennu, the safer Earth will be.When Osiris-Rex blasted off in 2016 on the more than 0 million mission, scientists envisioned sandy stretches at Bennu. So the spacecraft was designed to ingest small pebbles less than an inch (2 centimeters) across.Scientists were stunned to find massive rocks and chunky gravel all over the place when the spacecraft arrived in 2018. And pebbles were occasionally seen shooting off the asteroid, falling back and sometimes ricocheting off again in a cosmic game of ping-pong.With so much rough terrain, engineers scrambled to aim for a tighter spot than originally anticipated. Nightingale Crater, the prime target, appears to have the biggest abundance of fine grains, but boulders still abound, including one dubbed Mount Doom.Then COVID-19 struck.The team fell behind and bumped the second and final touch-and-go dress rehearsal for the spacecraft to August. That pushed the sample grab to October.“Returning a sample is hard,” said NASA’s science mission chief, Thomas Zurbuchen. “The COVID made it even harder.”Osiris-Rex has three bottles of nitrogen gas, which means it can touch down three times — no more.The spacecraft automatically will back away if it encounters unexpected hazards like big rocks that could cause it to tip over. And there’s a chance it will touch down safely, but fail to collect enough rubble.In either case, the spacecraft would return to orbit around Bennu and try again in January at another location.With the first try finally here, Lauretta is worried, nervous, excited “and confident we have done everything possible to ensure a safe sampling.”___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

A white man who allegedly killed two people at a Kroger grocery store in Kentucky tried to enter a predominantly black church nearby minutes before the fatal shooting, police said.The two people killed Wednesday -- Maurice Stallard and Vickie Jones -- were shot in the grocery store and the parking lot, respectively. CNN affiliate WDRB described both victims as black.Police arrested suspect Gregory A. Bush, 51, shortly after the shooting, which happened in the Louisville suburb of Jeffersontown.  513

Air Line Pilots Association (ALPA) announced that they agreed with United Airlines not to furlough any of its pilots.In a press statement, the ALPA said the agreement keeps all 13,000 pilots employed and cancels the 2,850 previously announced layoffs.The planned layoffs were to take place Thursday when the CARES Act pandemic payroll support expired, USA reported.The Cares Act provided a billion bailout to keep US airlines afloat during the COVID-19 pandemic.Lawmakers are looking to extend the program by introducing a new bill to protect workers' jobs until March 31.Sen. Roger Wicker (R-Miss.) and Sen. Susan Collins (R-Maine) introduced the Air Carrier Worker Support Extension Act of 2020 last week."The CARES Act successfully saved thousands of jobs that support the airline industry and provided these businesses with some breathing space after the drastic drop in air travel caused by the COVID-19 pandemic," said Wicker in a press release. "However, the market has not turned around as much as we had hoped, and additional relief is needed to prevent more than 60,000 aviation sector employees from losing their jobs beginning October 1. This legislation would extend the critical Payroll Support Program to provide support for passenger air carriers, cargo air carriers, and aviation contractors. It would also preserve our nationwide service by requiring airlines to maintain routes as a condition for receiving assistance. Maintaining a strong national air transportation system is critical for today's economy and the continued recovery."The ALPA says the deal also offers pilots over the age of 50 with 10 years of experience second round of first separation options. It would also reduce or terminate the effect of temporary work reductions based on a recovery in passenger demand or other market factors, the ALPA said. 1850
