Even before a show based on the Chernobyl disaster renewed interest both on and off social media, one of the most vivid online reminders of the April 1986 nuclear reactor meltdown continued to circulate online.A Facebook post that was shared more than 36,000 times on the platform in December 2019 contains a photograph of shows one of the remnants of the meltdown alongside a short description:The photo above is the closest humanity has ever come to creating Medusa. If you were to look at this, you would die instantly.The image is of a reactor core lava formation in the basement of the Chernobyl nuclear plant. It’s called the Elephant’s Foot and weighs hundreds of tons, but is only a couple meters across.Oh, and regarding the Medusa thing, this picture was taken through a mirror around the corner of the hallway. Because the wheeled camera they sent up to take pictures of it was destroyed by the radiation. The Elephant’s Foot is almost as if it is a living creature.The post is a reprinting of a 2012 Tumblr post about the Elephant’s Foot, one that is accurate about the origin of the photograph and not far off from the truth about the consequences of being in the presence of the toxic mix of uranium, silicon dioxide, and other materials — which is still active. Dozens of workers died during the explosion and subsequent cleanup efforts due to acute radiation syndrome.As the science magazine Nautilus reported in 2013:After just 30 seconds of exposure, dizziness and fatigue will find you a week later. Two minutes of exposure and your cells will soon begin to hemorrhage; four minutes: vomiting, diarrhea, and fever. 300 seconds and you have two days to live.Other images of the Elephant’s Foot have also gained notoriety. They are believed to have been taken 10 years after the fatal meltdown by a man identified as Artur Korneyev:In 2014, Korneyev was interviewed by the New York Times for a story on the construction of a $1.5 billion structure that would cap airborne emissions from escaping the site of the former reactor:Artur Korneyev, 65, a radiation specialist, at his home in Slavutich. After the accident, his job was to locate radioactive fuel on site and determine radiation levels to limit the exposure of other workers.These days Mr. Korneyev works in the project management unit, but because of his health — he has cataracts and other problems related to his heavy radiation exposure during his first three years — he is no longer allowed inside the plant. “Soviet radiation,” he joked, “is the best radiation in the world.”The site of the reactor and the neighboring town of Pripyat were made open for tours by the public in 2011. In 2019 the pop culture site Consequence of Sound reported that the success of the HBO show Chernobyl, a dramatization of the fatal disaster, led to a 35 percent increase in tour bookings compared to 2018. But one of the side-effects of that increased attention was an influx of visits from social media “influencers,” who would post “sexy” photographs of themselves in the area.“If you visit, please remember that a terrible tragedy occurred there,” series creator Craig Mazin posted in response. “Comport yourselves with respect for all who suffered and sacrificed.”

The test examines more than 2 million spots in a person’s genetic code, seeking variants that individually nudge a person’s obesity risk up by a tiny amount. The researchers drew on previously published data about those variants to create a risk score. A high score didn’t guarantee obesity, nor a low score rule it out. But middle-aged people with scores in the top 10 percent were 25 times as likely to be severely obese as those in the bottom 10 percent, scientists reported in a paper released Thursday by the journal Cell. Those two groups were separated by an average weight difference of about 29 pounds (13 kilograms), researchers said. Analysis showed the genetic propensity to obesity began having an effect on weight around age 3. Up to about age 8, “you might be able to make a difference in the kids who are born susceptible to obesity,” said one author of the study, Dr. Sekar Kathiresan of Massachusetts General Hospital in Boston and the Broad Institute of MIT and Harvard. But it will take further research to see whether intervening would work, Kathiresan said. The results for middle age came from a study of about 288,000 people. Overall, the risk-score research included data from more than 300,000 people at various ages. Severe obesity was defined as a body mass index of 40 or more. Results show genetic inheritance “plays a large role in how heavy one gets,” Kathiresan said. The risk score probably takes about half of a person’s genetic propensity into account, he said, and it shows similar accuracy in predicting ordinary obesity, defined as a BMI of 30 or more. Even if one inherits a propensity for obesity, he said, “you still have control over your fate. You’re not fated to be obese, but it’s very clear those individuals who’ve inherited susceptibility have to work that much harder to keep the weight off.” Among study participants with the highest scores, he noted, 17 percent were of normal weight. Other analyses show that people who remain lean despite an inherited propensity for obesity tend to eat better and have more physical activity than others with a high score who got fat. “So you can do something about it,” he said. Ruth Loos, a professor of environmental medicine and public health who did not participate in the study, said the risk score explains more of people’s genetic tendency than previous studies did. But she doubted it would be useful in a doctor’s office. It is “never going to be a good predictor,” said Loos, of the Icahn School of Medicine at Mt. Sinai in New York. She noted that in one test of the score’s predictive power, only 58 of the 371 subjects scoring in the top 10 percent ended up severely obese. And many other severely obese people didn’t score in the top 10 percent, she said. Simply asking about family history of obesity would probably work better, she said. The large role of lifestyle in obesity means a purely gene-based predictor will never be perfect, she said. Kathiresan, a cardiologist, said the risk score is best seen as a risk indicator, like high cholesterol. Most people with high cholesterol don’t get heart attacks, he said, but they do run a higher risk than others. Jason Boardman of the University of Colorado Boulder said genetic variants might affect body size indirectly, through an impact on lifestyles or other social and behavioral traits. Other research suggests the effect of genes on size depends on what kind of social and physical environment a person lives in, including such factors as access to unhealthy foods, he said in an email. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The health director for Ridgefield, Connecticut, says there is no way that he and his staff of two can identify and isolate all the people who have interacted with an infected patient, not at the rate cases are multiplying across the town. “Tracing exposures of exposures of exposures. It’s just impossible,” Briggs said. “The cases are to the point where we can’t possibly trace everybody back now.”  Known as contact tracing, this vital but labor-intensive process is becoming increasingly difficult for stretched health departments in towns and cities across the United States, which has more than 160,000 cases, more than any country in the world. A massive testing campaign, coupled with intensive contact tracing, is credited with helping South Korea slow the spread of coronavirus, whereas the United States has been criticized for a slow response. Epidemiologists say such investigations can mean the difference between nipping an outbreak early and effectively losing control, as has happened in hot spots where contact tracing has given way to lockdowns as the primary tool to prevent spread. Some states outside of the major population centers have taken that advice to heart, as the virus continues its march across the United States. Health officials in those areas acknowledge, however, that it is a race against the clock and that they, too, will be unable to carry out such widespread tracing if the case numbers climb beyond a certain point. Wyoming, for one, has five staff in its state’s infectious diseases unit working to identify all contacts with a person who has tested positive, and then asking or ordering them to self-quarantine, and monitoring their health. “Our numbers are small enough,” said Kim Deti, a spokeswoman for Wyoming’s health department, which has reported 109 cases so far and no deaths. “We’ll maintain it as long as we can.”  West Virginia is tapping its national guard to assist in a similar effort at expansive contact tracing, and coupling that with a stay-at-home order and other distancing steps. On Sunday, the state reported 145 cases and its first coronavirus death. “It’s incredibly important that at the same time as you are doing that rapid contact investigation and tracing and outbreak management, that we do the preventive measures in partnership with that everywhere,” state health officer Cathy Slemp said at a news conference last week. Alabama, which has confirmed nearly 1,000 cases, is attempting to investigate contacts for all of them, a spokeswoman for its health department said, noting that contact tracing has been an “effective tool in reducing the spread” for tuberculosis and other communicable diseases in the state. New York City, which accounts for a quarter of all cases nationwide, is an example of how the lack of testing in January and February handicapped so-called “disease detectives” from identifying initial infections and containing the spread. The city is now limiting its detectives to contact tracing for outbreaks involving health care workers and clusters in assisted living facilities and nursing homes, its health commissioner, Oxiris Barbot, said during a news conference earlier this month. Louisiana, an emerging hot spot with 5,237 cases and 239 deaths, has similarly narrowed its contact tracing in the New Orleans area, the epicenter of the state’s outbreak, to focus on vulnerable populations and high-risk groups. Theresa Sokol, an assistant state epidemiologist in Louisiana, said that by the time the initial patients in the New Orleans area were identified the virus had already taken hold in the community. As cases mounted, she said, social distancing became a more effective tool than contact tracing. But outside New Orleans there is reason to believe that digging deeply into all cases can yield results, especially when combined with the governor’s statewide stay-at-home order, Sokol said: “I believe that there is still time.”  Like other municipalities in the New York area, Ridgefield closed its schools and non-essential businesses. But the virus has continued to spread broadly beyond the cluster at the Benchmark Senior Living at Ridgefield Crossings facility, which has been linked to six of the town’s seven deaths. The town hired an additional employee to process the deluge of coronavirus-related data, but keeping up is a challenge. “It’s overwhelming for a small health department,” First Selectman Rudy Marconi said. Looking ahead, experts see aggressive testing and contact tracing as key to handling subsequent waves of the virus. Kenneth Castro, a professor of global health, epidemiology, and infectious diseases at Emory University, said local, state and federal governments should start recruiting an “army” of people to handle contact investigations. “Identify and contain is better than having society shutdown. It’s a balancing act,” said Castro, who oversaw the Centers for Disease Control and Prevention’s tuberculosis effort for two decades through 2013. “We won’t be able to maintain physical distancing forever.”  (This story has been refiled to correct spelling of “stretched” in paragraph four.)
