EL CAJON (CNS) - A pedestrian was struck by a vehicle and killed in El Cajon, authorities said Friday morning.Officers responded to the intersection of Washington and South Orange avenues about 11 p.m. Thursday, where they found a woman in her 50s with significant head injuries. She was pronounced dead at the scene, according to Lt. Jeremiah Larson of the El Cajon Police Department.An investigation determined the woman was crossing the road when she was struck by the vehicle traveling westbound on Washington Avenue, Larson said. It was unclear whether the woman was in a marked crosswalk at the time of the crash.Alcohol or drugs were not considered factors in the crash, he said, but no other details were released.The name of the victim was not disclosed. 771

During this pandemic, people aren’t interacting like they used to.Many schools have moved online, restaurants have moved outdoors, and public transportation is spacing out its seating.With less face-to-face interaction in the real world, scientists are now turning to artificial intelligence.“Robots are our friends,” said Jeffrey Krichmar, Ph.D., a professor of cognitive sciences at the University of California, Irvine (UCI).Recently, Krichmar’s team started testing socially assistive robots with the goal of helping people perform household chores, accomplish health care tasks and even offer them emotional support.“That could be very helpful if a person is impaired and can’t get help in the home because they’re locked down or quarantined,” he said.Krichmar says there’s a lot of societal benefits with this technology, too, like helping people cope with their feelings during isolation.“If I’m not able to get to you, but you have a robot there I can log on through the robot, have a conversation with you and then maybe do tasks around the house with a robot,” he said.Many of UCI’s robotic projects involve the Toyota Human Support Robot.“When you think about the social interaction, I think we’re all feeling this right now,” said Douglas Moore, Toyota’s director of technology for human support.Moore says working with UCI during the COVID-19 crisis could help many people both physically and emotionally.“One of the silver linings that I think we’re going to get out of this pandemic that we’re currently in, we’re going to develop a little bit more sympathy and empathy for the communities that idea with this on a day-to-day basis that have no real light at the end of the tunnel,” he said.Project leaders hope to get more of these robots in people’s homes“The ones that we’re doing with Toyota, they’re not commercially available yet and the ones that are a little pricey,” Krichmar said. “They’re like an expensive luxury car right now.”Krichmar believes more interest could help lower the cost of these robots and that more attention could create future innovation.“This pandemic is our Fukushima moment in a way,” Krichmar said of the COVID-19 crisis.“If this drags on a lot longer, it might be actually useful for this particular crisis,” he said. “But I’m almost thinking like the next crisis down the road.” 2338

Dining out frequently is known to increase one's intake of unhealthy sugars and fats. But a new study suggests that there's another reason to eat at home more often: phthalates.Phthalates are potentially harmful chemicals found in hundreds of consumer products, including perfumes, hair sprays, shampoos and the plastics used in food processing and packaging.Consumption of these chemicals has?been linked to birth defects in young boys as well as behavioral problems and obesity in older children and adults. Exposure in utero can alter the development of the male reproductive tract, resulting in incomplete descent of one or both testicles.Scientists also suspect that the chemicals can disrupt hormones and may cause fertility problems. They've connected them to childhood obesity, asthma, neurological problems, cardiovascular issues and even cancer."Phthalates are a class of synthetic chemicals known as endocrine disruptors, meaning they affect hormones in the body," said Dr. Sheela Sathyanarayana, an associate professor of pediatrics at Seattle Children's Hospital and the University of Washington and past chairwoman of the Environmental Protection Agency's Children's Health Protection Advisory Committee, who was not involved in the study. "Hormones are essential for normal body functions such as reproduction or metabolism."The?study, published Wednesday in the journal Environment International, found that the phthalate levels of participants who had eaten at restaurants, cafeterias and fast-food outlets in the previous day were 35% higher than those who reported eating food purchased at the grocery store.Those who dined out were probably exposed to the chemicals via foods that had been in contact with plastic packaging, said Ami Zota, an assistant professor of environmental and occupational health at George Washington University and a leading author on the study."The main idea is that food that is made in restaurants and cafeterias may be coming into contact with materials containing phthalates in part because some portion of the food is made in decentralized locations," Zota said."Most of the phthalates that are of most concern from a health perspective are plasticizers; they're added to make plastics soft," she added. "They're added to food packaging, they can be in food handling gloves, and they can be found in food tubing."The study relied on data collected between 2005 and 2014 from the National Health and Nutrition Examination Survey, administered every two years by the US Centers for Disease Control and Prevention. It included 10,253 people who were asked about their dining habits over the past 24 hours and who provided urine samples to evaluate phthalate levels in the body.The researchers found that about two-thirds of respondents reported dining out at least once the previous day. Those who dined out also had significantly greater levels of phthalate metabolites in their urine.This association was consistent across all ages, genders and ethnicities, but it was strongest among teenagers who ate out: They had phthalate levels 55% higher than those who ate at home."The association between phthalate exposure and dining out existed in all age groups, but the magnitude of the association was highest for teenagers," Zota said. "Certain foods, especially cheeseburgers and other sandwiches, were also associated with increased levels of phthalates, but only if they were purchased from a dining-out establishment."This is not the first time phthalate levels have been linked to food sources. In 2016, Zota led?a study?that showed a connection between phthalate exposure and fast-food restaurants. The new study expands on this research by showing that the link persists even when eating at other types of establishments, such as sit-down restaurants and cafeterias, she said."We first used this methodology to focus on fast food and found some striking associations between recent fast food consumption and phthalate exposure," Zota said. "And now, we extended that to see if the findings were unique to fast food, or how do they compare to other food outlets that may reflect other types of food processing and manufacturing systems?"Last year,?a report found high concentrations of phthalates in macaroni and cheese mixes, which prompted a push for additional regulation of the chemicals in food. Although the US Food and Drug Administration monitors levels of phthalates in a number of cosmetics, it does not regulate its presence in food or beverage products."Policy would need to focus on reducing phthalate exposures in food production processes. Food manufacturers would need to know about sources of contamination and work to reduce these," Sathyanarayana said. "The other way to approach it is to either reduce or ban phthalate use in food manufacturing."The good news, though, is that phthalates linger in the body for only about a day. Changing your eating habits and consuming more home-cooked meals could therefore have almost immediate health benefits, according to Zota."Preparing food at home may represent a win-win," Zota said. "Home-cooked meals can be a good way to reduce sugar, unhealthy fats and salt, and this study suggests that they may not have as many harmful phthalates as restaurant meals."The other important point is that these chemicals are ubiquitous in the environment," she added."So, to really reduce everyone's exposure to these potentially harmful chemicals, we need systemic changes to how our food is produced and transported, and that's going to require changes in policy as well as market-based solutions." 5643

Dr. Anthony Fauci, the nation's top infectious disease expert, called for the U.S. to "double down" on what he called "common-sense" public health measures on Monday as the country faces a critical juncture amid the COVID-19 pandemic.After enormous surges in cases in the spring and summer, the U.S. was able to flatten the curve a bit in early September. According to Johns Hopkins, the U.S. dropped to a low point of about 34,000 new daily cases of COVID-19, down from a high of about 70,000 new cases in July.However, case rates have increased gradually in recent weeks, and Fauci warned that Americans need to take public health measures seriously as cold weather forces many indoors, adding that the country is "not in a good place" ahead of winter."(Some states) are starting to show upticks in cases and even some increase in hospitalizations in some states," Fauci said Monday during an appearance on ABC's Good Morning America. "You don't want to be in a position like that as the weather starts getting cold."Fauci added that despite the increase in cases, he did not believe the U.S. needed to go into another total lockdown similar to the one that took place in March and April."I would really like to not go there because it causes so many collateral issues and problems," Fauci said. "...obviously, if things really explode, you'd have to consider that. But we want to do everything we possibly can to avoid an absolute shutdown. In other words, get the cases under control by the common-sense types of things that we've been talking about all along, those public health measures."However, Fauci said he was "concerned" by Florida's decision to reopen bars and restaurants. On Friday, Florida Gov. Ron DeSantis moved the state into "Phase 3" of its reopening plan, meaning that restaurants, bars and hotels can operate at full capacity. Local governments are also unable to restrict a business' operating capacity unless granted permission by the state.Fauci said he was specifically troubled by the state's reopening of bars."That is very concerning to me," Fauci said. "We have always said that — myself and Dr. Deborah Birx, who is the coordinator of the task force — that that is something that we really need to be careful about, because when you're dealing with community spread, and you have the type of congregate setting where people get together, particularly without masks, you're really asking for trouble."In the past, Fauci has advocated for five common-sense public health measures that all Americans should take amid the pandemic: Wearing masks, avoiding crowds, keeping six feet apart from others, constant hand washing and opting for outdoor activities over indoor activities. He says if the U.S. continues to follow those guidelines, the country can continue to open up the economy."If you (open the economy) in a prudent way — in a prudent way means focus on things that are important — you can open businesses, you can do things like that," Fauci said. "But when you start opening up bars without masks or congregate settings where people are indoors without masks, that's asking for trouble." 3136

Donald Trump’s official campaign account was briefly blocked from posting on Twitter on Wednesday. Twitter claimed that a post by the campaign was misleading and violated its service terms.While Trump did retweet the post on his personal account, he did not have his access revoked.The campaign resumed access to the account later on Wednesday.Meanwhile, Facebook has deleted a post by President Donald Trump for the first time, saying it violated its policy against spreading misinformation about the coronavirus.The post in question featured a link to a Fox News video in which Trump says children are “virtually immune” to the virus. Facebook said in a statement Wednesday that the video includes false claims that a group of people is immune from COVID-19.It says that is a violation of its policies around harmful COVID-19 misinformation. 851
