Tall people are at a greater risk of cancer because they have more cells in their body, new research has suggested.A person's risk of developing cancer increases by 10 percent for every 10 centimeters (4 inches) they are over the average height, the study said, because they have more cells which could mutate and lead to cancer.Average height was defined in the study as 162cm (5 feet, 4 inches) for women and 175cm (5 feet, 9 inches) for men.The findings match with previous research, which has also connected height to an increased risk of developing a range of health problems including blood clots, heart problems and diabetes.Leonard Nunney, a professor of biology at the University of California Riverside, analyzed previous sets of data on people who had contracted cancer -- each of which included more than 10,000 cases for both men and women -- and compared the figures with anticipated rates based on their height.He tested the hypothesis that this was due to the number of cells against alternatives, such as possible hormonal differences in taller people, which could lead to an increased rate of cell division.A link was found between a person's total cell number and their likelihood of contracting cancer in 18 of the 23 cancers tested for, the study says.The research also found that the increase in risk is greater for women, with taller women 12 percent more likely to contract cancer and taller men 9 percent more likely to do so. Those findings matched with Nunney's predicted rates, using his models, of 13 percent for women and 11 percent for men.Colon and kidney cancer and lymphoma were among the types of cancer for which the correlation was strongest."We've known that there is a link between cancer risk and height for quite a long time -- the taller someone is, the higher the cancer risk," Georgina Hill from Cancer Research UK told CNN."What we haven't been sure of is why -- whether this is simply because a taller person has more cells in their body, or whether there's an indirect link, such as something to do with nutrition and childhood," added Hill, who was not involved in the study.She said the study provides good evidence of the "direct effect" theory that the total number of cells does indeed cause the link."The methodology is good - they took data from large studies, which is important, and they looked at lots of different categories of cancer."But she noted that the increase in risk of developing cancer is small compared to the effects that lifestyle changes can have."It was only a slightly higher risk and that there are more important actions that people can take to make positive changes, [such as] stopping smoking and maintaining a healthy weight," she said.Two of the types of cancer tested for, thyroid cancer and melanoma, were found to be more susceptible to an increase in risk than expected, and Nunney suggested in the study that other factors could be at play in those cases, such as geography."There are no obvious reasons for these exceptions, although the author speculates that cell turnover rates may come into play for melanoma," Dorothy C. Bennett, director of the Molecular and Clinical Sciences Research Institute in London told CNN. Bennett, who was not involved in the study, explained that pigment cells, the source of melanoma, divide and are replaced a little faster in taller people."But I cannot at present think of any reason why this [faster division] should be so, but nor any other clear reason for the higher correlation with height," Bennett said. 3548

THANK YOU DAVE FOR HOPPING ON A JET TO COME SEE ME DOING WELL DAVE YOU ARE A GOD SEND AND A TRUE FRIEND ALL LOVE ?? pic.twitter.com/ddLA0E9eLK— ye (@kanyewest) July 21, 2020 190

SYRACUSE, New York — It’s training many teachers have never seen, and it’s designed to let staff feel what it might be like to have a school shooter attacking.These teachers are physically learning to team up and do battle with a shooter, and they are being taught to focus on a shooter's hands.Teacher’s aid Melissa Demjanenko used tennis balls to train in place of staplers, tape dispensers or chairs she would really use to defend her classroom."I think of myself as not a powerful person. ... What can I do to stop something? Now I know I can do something. Now I know everyone in this room can do something," Demjanenko said.The training considers the idea that when people are in the most stressful situation of their lives, and they think they're just going to react a certain way ... they recognize they won't, Sheriff’s Deputy Tom Czyz said.People need muscle memory, and to get that, a person needs to have gone through similar stress, he said.Czyz started the training company Armored One.He says running to safety is your best bet, then hide if you can’t run.Along with other current and former law enforcement he teaches teachers lessons that go beyond the classroom and beyond the school lessons we can all use if running or hiding aren’t an option.“Your game plan of what you will do in case something happens: I hear gunshots behind me in front of me next to me. Which way am I going? What am I doing if I have to fight back.? What am I going to use for weapons? ... Literally in a few seconds."Everywhere you go you can have these plans already and it could save your life," Czyz said.We asked if he does that in every building he goes into. “Absolutely.”Police officers regularly train at the gun range; flight attendants on the airplane train for weeks to help people get out alive. This is why some school districts have decided teachers also need to train physically — to protect students.Before this training, in a mock active shooter drill — teachers reacted painfully slow, taking more than 30 seconds to exit the room.Czyz was brutally honest.“If my own kids were in here, I would be disgusted with you. Pretend like your own kids are in here, right?" he said.Czyz's team demonstrated how to barricade a door and use other things around to block and protect one's self. The taechers then tried again.There was a huge difference after the training — teachers cleared the room in around 10 seconds.The sheriff's department says it works hard to make sure the teachers are in their space, so training is done in the school where the teachers actually work. They get first-hand experience in their building.Planning ahead and practicing is what these teachers say now gives them the confidence to wage war against an attacker if they have no other choice. 2858

TAMPA, Florida — Police said they got a big win Friday night after they were able to arrest a man wanted in connection to installing credit card skimming devices across the Tampa Bay area.Police on scene told ABC Action News they were able to take the skimmer into evidence after a customer at the Chase Bank at 2001 N. Dale Mabry pulled it off the drive-up ATM while getting cash out.That customer flagged an officer down and showed him the skimmer. What that customer didn’t know is that undercover officers were already in pursuit of the man. Officers on scene say he was wanted by multiple agencies.The man, who has been identified as Yanier Manso Caballero from Hialeah, ditched his black Mercedes in the McDonald’s parking lot next to the bank, kicked off his flip flops, and took off running as officers tried to make an arrest.The police helicopter was able to lead K-9 officers to a heat signature of a man inside a shed on West Cherry Street, about a quarter mile away from the bank. The man was taken into custody a short time later.The customer that found the skimmer told officers on scene that he saw at least two other customers get cash out before he found the skimming device. There is no information, at this point, about how long the device might have been on the ATM. 1305

The Asian giant hornet first made waves this spring when it appeared in the United States. Discovered in Washington State, some dubbed it the murder hornet, but since then, entomologists have been feverishly trying to eradicate it."Quite a bit has happened. First, we had an initial planning with our AFS counterparts and also our counterparts in Canada who are having detections of their own. We formulated one or two different plans and put one or two of them into action," says Sven-Erik Spichiger, the Managing Entomologist at the Washington State Department of Agriculture.The Asian giant hornet is the world's largest hornet. It's more than two inches long, and queens can be even bigger. They feed on honey bees, attacking and killing tens of thousands of them at a time.Last November, beekeeper Ted McFall was blown away when he discovered one of his strongest hives had been attacked."Every time I go and check my hives, I kind of have a bad feeling when I start thinking about the Asian giant hornets that are somewhat establishing nests in the woods around me because I think to myself, 'Which one of these colonies is going to get it? Next time I come out here, am I going to show up and there's going to be bee heads everywhere and just bee carnage everywhere?' It's a very unsettling feeling," says McFall.The Asian giant hornet has been spotted and caught near McFall's property. Spichiger says the Washington State Department of Agriculture and the surrounding community have been hard at work setting traps."We have an excellent public survey going on with over 1,000 traps established by just members of the general public. This is very heartwarming to me because it means everyone is taking it very seriously and going above and beyond to help us look for new detections of this invasive pest," says Spichiger.Spichiger says so far, one has been discovered just over the Canadian border and three in Whatcom County in Washington State. Two of those discovered were queens, which is crucial since the Asian giant hornet hive can't survive without its queen. There have also been two cases where people were likely stung by an Asian giant hornet."She described being stung as having hot tacks driven into her flesh... What she described seeing in the yard earlier that day sounded like an Asian giant hornet. Again, it's an unconfirmed report, but we believe it happened," says Spichiger."Beekeepers have all types of bee equipment and protection against bees but this is totally useless against the Asian giant hornet. The Asian giant hornet can poke his stinger right through here. Even if I wore two of them," says McFall.As for whether Washington State agriculture officials feel they're closer to eradicating the Asian giant hornet, Spichiger says: "Eradication is going to be a long process. We will only know for sure if we’ve been successful if we have three years of all negative surveys and nobody turns any in. So from a realistic sense, no, I’m three years away."Still, the capture of the Asian giant hornets, including the two queens, is progress.McFall has 16 traps set up within a mile of his hives. He's on high alert, hoping none of his honey bees get attacked again."This is a [container] with orange juice and rice wine. They'll smell it and go through the hole. That hole is a little bit narrower than 3/4 inch and then they'll go in and not find their way out. They'll try and fly out and not be able to get out," says McFall.The traps are the same used by entomologists at the Washington State Department of Agriculture. Entomologists will be setting another 40 live traps near the most recent sighting. They're hoping to catch a live Asian giant hornet and tag it so they can track it to their nest. 3747
