SAN FRANCISCO, Calif. -- Police in San Francisco made a horrifying discovery after a man was reported missing.According to KRON, police found the remains of a headless torso in a fish tank inside a San Francisco home.Neighbors hadn’t seen the homeowner in months and police were called to the home in July to do a wellness check, but men inside the home said the homeowner was simply on vacation.After returning to the house, police found the remains they say were so badly decomposed, they couldn't tell whether the victim was a man or a woman. One man was arrested in the case, but charges have yet to be filed. 626

Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere.The research by scientists at Harvard and Yale universities, published in the journal Environmental Research Letters, proposes using a technique known as stratospheric aerosol injection, which they say could cut the rate of global warming in half.The technique would involve spraying large amounts of sulfate particles into the Earth's lower stratosphere at altitudes as high as 12 miles. The scientists propose delivering the sulfates with specially designed high-altitude aircraft, balloons or large naval-style guns.Despite the technology being undeveloped and with no existing aircraft suitable for adaptation, the researchers say that "developing a new, purpose-built tanker with substantial payload capabilities would neither be technologically difficult nor prohibitively expensive."They estimate the total cost of launching a hypothetical system in 15 years' time at around .5 billion, with running costs of .25 billion a year over a 15-year period.The report does, however, acknowledge that the technique is purely hypothetical."We make no judgment about the desirability of SAI," the report states. "We simply show that a hypothetical deployment program commencing 15 years hence, while both highly uncertain and ambitious, would indeed be technically possible from an engineering perspective. It would also be remarkably inexpensive."The researchers also acknowledge potential risks: coordination between multiple countries in both hemispheres would be required, and stratospheric aerosol injection techniques could jeopardize crop yields, lead to droughts or cause extreme weather.The proposals also don't address the issue of rising greenhouse gas emissions, which are a leading cause of global warming.And despite the conviction of the report's authors, other experts were skeptical."From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more costly and much more risky over the long run," said Philippe Thalmann of the école Polytechnique Fédérale de Lausanne, an expert in the economics of climate change.David Archer of the Department of Geophysical Science at the University of Chicago said, "The problem with engineering climate in this way is that it's only a temporary Band-Aid covering a problem that will persist essentially forever, actually hundreds of thousands of years for fossil fuel CO2 to finally go away naturally."It will be tempting to continue to procrastinate on cleaning up our energy system, but we'd be leaving the planet on a form of life-support. If a future generation failed to pay their climate bill they would get all of our warming all at once." 2830

Scientists and medical professionals across the country are working to learn about the coronavirus’s effect on children. There's still a lot they don't know about how the virus affects children.With children often not showing as many symptoms as adults, experts say kids can help us learn more about the novel coronavirus. Dr. Beth Thielen, a pediatric infectious disease physician and professor at the University of Minnesota, says people could be looking to children, especially as they go back to school, to find out more about the coronavirus."I mean, I hope so. I think this provides a very rich opportunity to understand a lot of basic things about the immune system and why diseases manifest differently in adults and children," says Dr. Thielen.Dr. Thielen says from possible protective measures of the MMR vaccine in children to t-cells, there's so much people can learn from how children's bodies combat viruses."It is thought that t-cells play a substantial role in helping to clear viral infections from the lungs. There are people looking at t-cell responses but they've lagged a bit behind with the data coming out on t-cell responses hasn’t been as prominent as the antibody studies," says Dr. Thielen. She adds, the reason people are looking at t-cells and children is because t-cells decline with age."I think they are critical. We all have them, they work to protect us from infection and potentially they are more efficacious in younger people potentially. Although, I think that really hasn’t been clearly worked out for SARS COV2," says Dr. Thielen.Dr. Jay Varkey, an epidemiologist at Emory Hospital in Atlanta, Georgia, agrees. Dr. Varkey says scientists are also looking into why children older than 10 years old, are more likely to have more serious symptoms with COVID-19."I think the reasons for that are complex. I think part of that might be related to some sort of existing t-cell immunity, and to what that is whether that’s to memory cells that are acting against a previous seasonal coronavirus that would just cause cold like symptoms, or whether its related to something more complex -- I don't think we’re there in terms of understanding," says Dr. Varkey.Dr. Varkey says, while children can help us understand COVID-19 better, it's also up to the adults to make sure they're growing up in a healthy, safe environment."We will learn much from kids but one of the messages we’ve been emphasizing in the hospital is that if we, again- and I answer this both not just as an infectious disease physician but also as a parent to two school age kids--we as adults have a responsibility to try and make our community safe to actually allow in-person learning," says Dr. Varkey."I think that we often think of children as getting a lot of these infections and the fact of the matter is most adults are getting exposed, as well, but our immune systems are sort of experienced at seeing them and we don't get sick," says Dr. Thielen.Dr. Thielen is a member of the Pediatric Infectious Disease Society and says she and other doctors in their scientific groups are advocating for more pediatric research to truly understand how certain diseases, including COVID-19, behave in children. 3217

SANTA CRUZ COUNTY, Calif. -- With wildfires burning across the West Coast and coronavirus concerns impacting communities, emergency evacuation shelters in California are facing crisis and chaos.In Santa Cruz County, leaders say local fires have displaced about one in every five residents.That includes Anthony Koppe, who lost his house in Boulder Creek during the CZU fire.“I don’t want to dwell on it too much. you know,” he said. “It’s happened and we got to move on.”Koppe and many others from California’s Central Coast are now seeking help at a local recovery resource center where new safety measures have been added to combat COVID-19.“If somebody has something, instead of passing it on, you can catch it at the door,” he said.Just to get in those doors, people have to pass a pretty strict health screening, like filling out an extensive questionnaire and getting your temperature taken with a new touchless thermometer.“It’s impacted everything,” Rosemary Anderson, emergency services manager for the County of Santa Cruz, said about how COVID-19 has changed how emergency evacuations shelters are operating.Gone are the days of hundreds of cots stuffed in an auditorium. Now, places like Kaiser Permanente Arena, which normally holds 25,000 people, has a maximum capacity of 68.“Everything was measured out so each of the tables and the resources are all 6 feet apart and people can interact from a distance where its COVID safe,” Anderson said.COVID-19 concerns have also impacted other disaster relief organizations.“Where we’d normally have 500 people in a gym, now we’re only doing about 50,” said Tony Briggs of the American Red Cross.Briggs says the coronavirus has forced his teams to change how they help people cope with disaster during this pandemic.“Now, with COVID, we can do all the listening, but you can’t do the contact,” he said. “And for some people, that hug is a really, really big deal.”Even with the added attention to detail, leaders in Santa Cruz are expecting coronavirus transmission rates to increase because more people are coming in contact at these resource centers.“If something is wrong with somebody, I definitely don’t want to catch it or my lady or my son,” Koppe said.While people like Koppe may have lost their homes, these new safety measures haven’t let them lose hope“It definitely gives me peace of mind,” he said. 2375

Scientists have discovered a pocket sized dinosaur forerunner that was just 4 inches tall. Named Kongonaphon kely, which means tiny bug slayer, the creature looked like a dinosaur but scampered the Earth earlier, predating both dinosaurs and flying pterosaurs. The fossils, dug up in Madagascar, date from 237 million years ago, according to a study Monday in the journal Proceedings of the National Academy of Sciences. 429
