More children have been diagnosed with acute flaccid myelitis, the polio-like paralyzing illness, according to numbers released Monday by the US Centers for Disease Control and Prevention.There have now been 106 confirmed cases of AFM in 29 states this year, according to the CDC, an increase of 16 since last week.There are also 167 possible cases of the illness, an increase of five from the previous week.Since 2014, there have been 430 confirmed cases of the rare disease, and 90% have been children, according to the CDC.AFM is a rare illness that affects the nervous system, especially the gray matter in the spinal cord, and causes muscle weakness and sudden onset of paralysis. There's a spectrum of how children can be affected: Some regain the use of their paralyzed limbs, while others are paralyzed from the neck down and can breathe only with the help of a ventilator.There is no cure and no vaccine.There is also no known cause. Although several neurologists who serve as advisers to the CDC say they feel sure that an enterovirus -- the same family of viruses that cause polio -- is most likely to blame, the CDC says it's still casting a net wide.The CDC's Dr. Nancy Messonnier said last week that the agency is considering the possibility that an infectious pathogen is causing AFM but added that "we're broadening our hypotheses."When asked whether a toxin or vaccines could be triggering AFM, Messonnier, director of the National Center for Immuniziation and Respiratory Diseases, replied that "we're not ruling anything out at this point."About three to 10 days before becoming paralyzed, nearly all children who developed AFM experienced a viral illness with symptoms such as fever and cough, the CDC reported last week.Viral illnesses are very common among children, and so it's not clear why only a relatively small number develop AFM. Even within the same family, several siblings can develop the same cold-like symptoms but only one becomes paralyzed.In a CNN story last month, several of the CDC's medical consultants and parents of sick children criticized the agency for being too slow to respond to the outbreak.Messonnier said last week that the agency had funded state health departments to increase physician awareness in identifying cases, increased its network of neurologists to assist with and confirm cases, and established an AFM task force of national experts.CDC spokeswoman Kristen Nordlund also said last week that the agency had assigned 14 officers from the Epidemic Intelligence Service -- known as "disease detectives" -- to help review reports of AFM cases."As a mom myself, I can certainly understand why parents are worried. I am concerned about this increase in AFM," Messonnier said. 2742

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

Most people, when they retire, get a gold watch. James Harrison deserves so much more than that.Harrison, known as the "Man With the Golden Arm," has donated blood nearly every week for 60 years. After all those donations, the 81-year-old Australian man "retired" Friday. The occasion marked the end of a monumental chapter.According to the Australian Red Cross Blood Service, he has helped saved the lives of more than 2.4 million Australian babies.First, a note about antibodiesHarrison's blood has unique, disease-fighting antibodies that have been used to develop an injection called Anti-D, which helps fight against rhesus disease.This disease is a condition where a pregnant woman's blood actually starts attacking her unborn baby's blood cells. In the worst cases, it can result in brain damage, or death, for the babies.Here's why:The condition develops when a pregnant woman has rhesus-negative blood (RhD negative) and the baby in her womb has rhesus-positive blood (RhD positive), inherited from its father.If the mother has been sensitized to rhesus-positive blood, usually during a previous pregnancy with an rhesus-positive baby, she may produce antibodies that destroy the baby's "foreign" blood cells. That could be deadly for the baby.How Harrison made a differenceHarrison's remarkable gift of giving started when he had major chest surgery when he was just 14, the Australian Red Cross Blood Service said.Blood donations saved his life, so he pledged to become a blood donor.A few years later, doctors discovered his blood contained the antibody which could be used to create Anti-D injections, so he switched over to making blood plasma donations to help as many people as possible.Doctors aren't exactly sure why Harrison has this rare blood type, but they think it might be from the transfusions he received when he was 14, after his surgery. He's one of no more than 50 people in Australia known to have the antibodies, the blood service says."Every bag of blood is precious, but James' blood is particularly extraordinary. His blood is actually used to make a life-saving medication, given to moms whose blood is at risk of attacking their unborn babies. Every batch of Anti-D that has ever been made in Australia has come from James' blood." Falkenmire said. "And more than 17% of women in Australia are at risk, so James has helped save a lot of lives."Why his donations were a game changerAnti-D, produced with Harrison's antibodies, prevents women with rhesus-negative blood from developing RhD antibodies during pregnancy. More than three million does of Anti-D have been issued to Australian mothers with negative blood types since 1967.Even Harrison's own daughter was given the Anti-D vaccine."That resulted in my second grandson being born healthy," Harrison said. "And that makes you feel good yourself that you saved a life there, and you saved many more and that's great.The discovery of Harrison's antibodies was an absolute game changer, Australian officials said."In Australia, up until about 1967, there were literally thousands of babies dying each year, doctors didn't know why, and it was awful. Women were having numerous miscarriages and babies were being born with brain damage," Jemma Falkenmire, of the Australian Red Cross Blood Service, told CNN in 2015. "Australia was one of the first countries to discover a blood donor with this antibody, so it was quite revolutionary at the time."  3451

Motorcycle land speed record holder Valerie Thompson survived a 343-mph crash while attempting to break the overall two-wheel record in Australia on Monday, according to Fox News.According to the report, the 49-year-old Thompson was going for the record at the Lake Gairdner World Speed Trials "when something went wrong during her run and the bike fell onto its side, digging a deep trench into the salt flats and spreading wreckage over a mile."Thompson's "Bub 7" motorcycle reportedly lifted off the ground, with its parachutes eventually allowing it to come to a complete stop. Thompson told Fox News that she's "doing OK" and is headed back to Scottsdale to determine what went wrong.Thompson earned the title of world's fastest female motorcycle racer when she topped out at 304.263 mph at the Bonneville Motorcycle Speed Trials in 2016. Known as "America's Queen of Speed," Thompson has won a number of racing awards and was featured in the 2013 documentary "Why We Ride." She is a vehicle presenter at Barrett-Jackson Auction Company and Metro Auto Auctions in Scottsdale, Arizona.  1148
