Contact has been lost with the Cassini spacecraft after it completed a "death dive" into the upper atmosphere of Saturn and transmitted its final signal, according to NASA.The spacecraft deliberately sank into Saturn's upper atmosphere at a high speed and plunged itself into the planet just after 6:30 a.m. ET Friday. Given the amount of time it takes signals to reach Earth, the final signal and last bits of data reached the Deep Space Network's Canberra Station in Australia about an hour and a half later.NASA confirmed the spacecraft's demise at 7:55 a.m. ET, as predicted. 587

CORONADO, Calif. (KGTV) -- Police arrested a second suspect Wednesday in the shooting of an 18-year-old Coronado High School student earlier this month during a jewelry sale meetup. According to police, Alejandro Guzman, 18, was arrested for his alleged involvement in the shooting of Jacob McKanry, who was shot on May 4 near Orange Avenue and 10th Street. Guzman was charged with robbery and transported to San Diego Central Jail. A 17-year-old male was arrested in Chula Vista on May 22 after police served three search warrants in connection to the shooting. That suspect was charged with attempted homicide, robbery, and assault with a deadly weapon.

COLORADO SPRINGS, Colo. — More than 150 students at Colorado College are being quarantined for the next two weeks after one tested positive for the COVID-19 over the weekend.“At first I was like, shocked, but after a little while it sunk in like, 'Wow, that’s 14 days in one room,'” said Colorado College freshman Andrew Kaelin.Kaelin and Oliver Kendall only met Saturday. On Sunday, these roommates found out they will be spending nearly every minute of the next two weeks with each other. Students are allowed to only leave the room for laundry, bathroom and water. Food for the day is delivered to the room.“It’s a good way to get to know someone,” Kendall said.Before moving in, all students were required to take a COVID-19 test and were asked to isolate in their dorm rooms until the results came back.Brian Young, with Colorado College, said the student who tested positive went into the hallway of the dorm rather than staying in the room.“Immediately, as we isolated, the individual did our contact trace, realized, unfortunately, (that they) didn’t follow the guidelines we were after,” Young said.Neither Young or the El Paso County Health Department could say exactly how many came in contact with the student. Whatever the number was, it was enough to lock down Loomis Hall and the 155 first-year students living there.“All of our students are doing fine. No one is symptomatic,” Young told KMGH.Young said anyone showing even one symptom will be tested immediately. Colorado College is also providing students the ability to speak to a mental health expert as needed. Young says students will be allowed to get some fresh air with supervision.This story was originally published by Gary Brode at KMGH. 1723

Could the no-calorie sweetener you rely on to replace sugar in your diet actually cause weight gain instead of the weight loss you were expecting?The answer may be yes, according to a new study."Artificial sweeteners are not risk-free," said Brian Hoffmann, assistant professor in the Department of Biomedical Engineering at the Medical College of Wisconsin and Marquette University, and a lead author of the study. "They are a very controversial topic when it comes to health and nutrition ... but they're so prevalent in society that I think we owe it to ourselves to try and figure out what's actually going on."Hoffmann presented his new research Sunday at the annual?Experimental Biology meeting in San Diego. Relying on rats and human cell cultures, his team identified a number of pathways linking artificial sweeteners with metabolic changes at the genetic level that could lead to diabetes and obesity. Specifically, the researchers found that three weeks of exposure to aspartame and acesulfame potassium -- two artificial sweeteners frequently combined in products such as Equal -- altered the expression of certain genes responsible for lipid metabolism in the cells of both rats and humans."Aspartame had some significant changes, and one of those was an increase in lipids in the bloodstream and a decrease in a biomolecule that is involved in clearing (lipids) from the bloodstream. And we saw the exact same thing with the acesulfame potassium," Hoffmann said."We then took those particular sweeteners and put them on endothelial cells -- the cells that line the blood vessels and would be exposed to them in the body -- and we detected a marked dysfunction, suggesting why sweeteners and diet soda have been linked to potential cardiovascular problems," he added.What was perhaps most surprising, according to Hoffmann, was that these metabolic changes did not occur in the presence of natural sugars such as glucose and fructose. This suggests that artificial sweeteners could contribute to metabolic disorders such as diabetes and obesity by an entirely different mechanism than natural sugars, he said.Artificial sweeteners appear to contribute to metabolic disorders by altering the activity of certain genes responsible for the breakdown of macromolecules such as fats and proteins, Hoffmann said. This is different from normal sugars, which contribute to cardiovascular disease through insulin resistance and by damaging the cells lining the body's blood vessels."People are generally consuming non-nutritive sweeteners believing they are a 'healthy choice,' but this may not be true," said research scientist Meghan Azad of the University of Manitoba in Winnipeg, who was not involved in the new study."This is especially important given the widespread and increasing consumption of artificial sweeteners in the general population and the increasing use of artificial sweeteners in our food supply," said Azad, who has authored a paper that reviewed a number of studies on the potential downside of artificial sweeteners on weight and health.According to Azad, over 40% of adult Americans consume no-cal sweeteners on a daily basis, and studies that measure the sweeteners in blood and urine show that many people who report not using artificial sweeteners are unknowingly consuming them.It's the latest assault in the ongoing debate over artificial sweeteners and their impact on health -- a debate that began when one of our most popular foods, sugar, turned sour in terms of health. 3527

Clark County Deputy Fire Chief Jon Klassen recalls a moment that occurred around 2 a.m.—just a few hours after the gunfire ceased at the Route 91 Music Festival.  He calls it “one of the most meaningful, symbolic things” he has ever seen in 30 years in the business.Klassen was working with other paramedics and a crime scene investigator, combing through the grisly aftermath of the concert grounds, helping to confirm fatalities when one woman in particular stood out.“She just was so beautiful and peaceful,” Klassen recalls. “And quiet.”He said it almost just looked like she was laying there, watching TV, when he noticed something around her eye.“Just one tear drop,” he said, still sounding like he has trouble believing what he saw. He remembers reacting to it and just thinking, “me too.”“I am so with you, dear.”Klassen would soon learn that this woman, one of the 58 victims whose lives were cut short by a gunman perched in a hotel room, was 46-year-old Lisa Patterson. A wife. A mother of three.Her husband, Robert, went through a 22-hour ordeal to track down his wife, as detailed in a heart-wrenching account in a local newspaper.Upon hearing word that this deputy fire chief had something he would like to share if it’s something Lisa’s family would want to hear, Robert contacted Klassen.“We had a great conversation. And it was comforting and closing and cathartic for him. And I was able to tell this 16-year-old kid, ‘Your mom was beautiful, and peaceful and quiet.’”The two have spent some time together since that initial phone conversation, and Klassen now considers Bob Patterson a friend.Despite the fact that it has been four weeks since the attack, very little information has come to light and many questions remain, including the timing of when security guard Jesus Campos, the first to arrive at the gunman’s room, arrived on scene. Authorities have offered varying accounts in the weeks since. There is also still no word on a motive.But none of that frustrates Klassen. He says these things take time and that investigators are doing their jobs as best they can.He prefers to focus on the good he has seen in the community since the attack, because he says that makes the healing process easier.“I think that people are helping us heal--and healing themselves in the process—by doing good things for other people.”Will Las Vegas rebound?“Absolutely,” he said, and added without missing a beat, “We already are.” 2466
