More than 120 people have been sickened since mid-May reportedly from bagged salad sold in Midwest grocery stores.Interviews with these people led the Centers for Disease Control and Prevention to connect the illnesses with certain bagged salad mixes containing carrots, red cabbage and iceberg lettuce sold at ALDI, Hy-Vee and Jewel-Osco stores in several Midwestern states.As of June 22, 2020, a total of 122 people with laboratory-confirmed Cyclospora infections associated with this outbreak have been reported from 7 states: Illinois (30), Iowa (54), Kansas (1), Minnesota (13), Missouri (7) Nebraska (8), and Wisconsin (9). Of the 122 reported illnesses, the CDC says 19 people have been hospitalized.Symptoms of Cyclospora include diarrhea, loss of appetite, cramping, bloating, nausea, fatigue, vomiting and low-grade fever. Symptoms without treatment can last weeks to a month.Below are the details of the recalled items:ALDI Little Salad Bar brand Garden Salad sold in Arkansas, Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, North Dakota, South Dakota, and Wisconsin.Hy-Vee brand 12-ounce bagged Garden Salad sold in Illinois, Iowa, Kansas, Missouri, Minnesota, Nebraska, South Dakota, and Wisconsin.Jewel-Osco Signature Farms brand 12-ounce bagged Garden Salad sold in Illinois, Indiana, and Iowa.The above products do not account for all of the illnesses according to the CDC, and they along with the FDA are investigating whether other products are a source of illness. 1500

More than 190,000 ceiling fans sold at Home Depot in the U.S. and Canada are being recalled after receiving reports that blades were detaching from the fan while in use, which the company said could cause injuries.According to the Consumer Product Safety Commission (CPSC), 182,000 of the Hampton Bay 54-inch Mara Indoor/Outdoor fans were sold in the U.S. in stores and online from April through October 2020. Home Depot also sold 8,800 fans in Canada.The CPSC said 47 reports of the blades detaching have caused two people being struck and four accounts of the blades causing property damage. It was not reported if the people hit were injured.The CPSC said the recalled fans come in matte white, matte black, black, and polished nickel finishes. The fans also came with a white color changing integrated LED light and remote control.UPC #Matte White082392519186Matte Black082392519193Black082392599195Polished Nickel082392599188Consumers are asked to immediately stop using the ceiling fans and inspect the ceiling fans using the instructions.The CPSC says if consumers observe "blade movement or uneven gaps between the blades and fan body or movement of the clip during the inspection," to immediately contact the distributor King of Fans for a free replacement ceiling fan. 1286

MINNEAPOLIS (AP) — A Minneapolis commission says it needs more time to review a City Council amendment to dismantle the Police Department in the wake of George Floyd's death, ending the possibility of voters deciding the issue in November. The Charter Commission has expressed concern that the process to change the city's charter was being rushed. Some commissioners said they were more concerned with making the right changes rather than making them fast. The amendment would have replaced the Police Department with a "Department of Community Safety and Violence Prevention" that backers said would take a more "holistic" approach. That approach hasn't been fully defined. 683

  

Neanderthals may not have been that different from us, after all.New evidence reveals that they created the world's oldest known cave paintings and even wore seashells as body ornaments. Both behaviors suggest that they thought symbolically and had an artistic sensibility like modern humans. Two studies published Thursday in the journal Science detail the latest findings."Undoubtedly it is showing that Neanderthals were thinking and behaving just like modern humans," Alistair Pike, co-author of the studies and professor of archaeological sciences at the University of Southampton, wrote in an email."We should no longer think of them as a different species, just humans in different places," he said.The new findings of symbolic thinking show that Neanderthals and modern humans were cognitively indistinguishable, the researchers said.Cave paintings and artifacts like painted seashells have long been regarded as the work of early modern humans, who were thought to have more advanced cognitive abilities than Neanderthals. Dating cave paintings can be a difficult process, and unreliable techniques never allowed for the possibility that these could be the work of Neanderthals.Until now, that is. A new technique called Uranium-Thorium dating is less destructive, is more accurate and can go back further in time than other methods. U-Th dating looks at the deposits of carbonate on top of the paint, which contain traces of uranium and thorium that indicate when those deposits formed. That allows the researchers to determine an age for what's under the deposits.The researchers applied this technique to paintings in the La Pasiega, Maltravieso and Ardales caves in Spain, which had never received "robust" dating. The paintings include red and black images of animals, dots, lines, disks and other geometric signs. There also are engravings, hand prints and hand stencils.Those hand stencils are particularly significant, and not just because they represent the hand size of a Neanderthal."A red line, a red dot or even a positive hand print could potentially be made 'accidentally,' " wrote Dirk Hoffmann, lead author of the studies and archaeologist with the Max Planck Institute for Evolutionary Anthropology, in an email."Of course, I am sure that this is not the case, since you would still need to bring [in] light and pigment, but one could argue that all you need is some pigment on your hand when you lean against a wall. A hand stencil cannot be explained like that. You have to hold your hand against the wall and the deliberately spray pigment over this. This is why we emphasize the hand stencil."The dating revealed that the cave art was created more than 64,000 years ago -- 20,000 years before modern humans appeared in what is now considered Europe.The shells were found in the Cueva de los Aviones, a sea cave in southeastern Spain. They are unique because they are perforated with holes and colored with red and yellow pigment. Others served as containers for the mineral pigments themselves. The pigments were used on the shells but could have also been used for the cave paintings and even as body paint.The deposit layer containing the shells dated to 115,000 years ago, which is even older than other shells recovered in Africa that were dated to modern humans."The standard archaeological interpretation of such finds is that they are body ornaments," Hoffmann said. "Similar finds were made in Africa or the Levant with similar age. In Africa or the Levant, these were made by modern humans, in Spain Neanderthals made them. So in terms of symbolism, early modern humans and Neanderthals were similar."The researchers are absolutely confident in their dating technique."We have spent 10 years refining the technique and have numerous quality controls," Pike said. "The dates respect the growth axis of the deposits we are dating, the oldest closest to the painting, the youngest at the surface."Once modern humans left Africa and migrated to Europe and other areas, mixing with the Neanderthals would've been inevitable. The researchers believe that the Neanderthals created this artwork on their own, without being influenced by any other population. But it's possible that they exchanged symbolism or that Neanderthals influenced the art and symbolism of modern humans. Modern humans were capable of symbolic behavior, so it "turns the who's copying who debate on its head," Pike said."The idea that culture only evolved with modern humans no longer makes sense," Pike said. Hoffmann suggested that Neanderthals now be referred to as "very close cousins" of modern humans.Is it possible that anyone else may have created the cave paintings?Pike said it is incredibly doubtful that a population of early modern humans migrated to Europe so early without any other evidence to suggest it."We cannot of course rule out that pre-Neanderthal populations made the art," Pike said. "This sounds like a project for the future."Hoffmann, Pike and their colleagues want to use their new dating technique in more caves in Spain, as well as France and Italy -- and anywhere else Neanderthals are known to lived.The findings also raise new questions for researchers."How far back does symbolic behavior go? Can it be traced to the last common ancestor of modern humans and Neanderthals? This is perhaps where we should be looking," Pike said. 5398
