[Q]: 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.

[Q]: The new rules, which have been opened to the public for consultation, will involve the establishment of a comprehensive "management system" covering the production, sale, utilization and recycling of thin plastic film in the countryside. Chinese farmers, mostly in the arid north and west, cover fields with vast amounts of "plastic mulch" to help maintain soil moisture and protect against pests. The technique has played an important role in boosting yields and raising the quality of crops, the agriculture ministry said in a notice. "But because of excessive use and inadequate recycling, agricultural-use plastic film pollution in some regions has been getting worse and worse, and it has already become a major environmental problem holding back the green development of agriculture," the ministry said. In areas of northwest China that made use of plastic mulch, contamination rates stood at an average of 36 kilograms per hectare, with the figure as high as 138 kilograms in some regions, it said. The new rules would force farmers to use only film that meets quality standards, and they must also collect plastic waste from fields before its expiry date and deliver to approved recycling outlets. They will also be encouraged to reuse old film. China is said to use about 2 million tonnes of plastic film every year to cover around 200,000 square kilometers of farmland, an area the size of Belarus. But government researchers say the recycling rate stands at just 180,000 tonnes. If uncollected, the plastic waste eventually degrades the soil and could also infiltrate crops, with one parliamentary delegate from Shandong warning in March that some of the province's exports of ginger and spinach had been contaminated. Beijing is aiming to make around 90% of its total farmland safe for agriculture by the end of next year, part of its efforts to guarantee food security.

[Q]: On 10 May 1991, a 14-year-old Boy Scout named David Hahn earned an Atomic Energy merit badge, the first (and likely only) person in the history of Troop 371 in Clinton Township, Michigan, to receive a badge in that discipline: David was awarded his Atomic Energy merit badge on May 10, 1991, five months shy of his fifteenth birthday. To earn it he made a drawing showing how nuclear fission occurs, visited a hospital radiology unit to learn about the medical uses of radioisotopes and built a model reactor using a juice can, coat hangers, soda straws, kitchen matches, and rubber bands. By now, though, David had far grander ambitions. Throughout his childhood, Hahn had been obsessed with chemistry, teaching himself everything he knew from encyclopedias, textbooks, and chemistry sets, while personal safety did not seem to be a concern of his. According to a 1998 Harper's profile of Hahn written by Ken Silverstein, "He once appeared at a scout meeting with a bright orange face caused by an overdose of canthaxanthin, which he was taking to test methods of artificial tanning." In another instance, he was held responsible for a blowing a large hole in the wall of a Boy Scout tent after accidentally igniting a stockpile of powdered magnesium he had brought along. His "laboratory" was eventually moved to the potting shed behind his mother's house, after an incident in his father's basement that did not go as planned: One night as [Hahn's father and stepmother] were sitting in the living room watching TV, the house was rocked by an explosion in the basement. There they found David lying semiconscious on the floor, his eyebrows smoking. Unaware that red phosphorus is pyrophoric, David had been pounding it with a screwdriver and ignited it. After achieving the rank of Eagle Scout, Hahn decided he wanted to experiment with real radioactivity, not merely the models he had used to earn his badge. He created various radioactive devices, including two different "neutron guns" that emitted radioactive particles, and eventually decided he wanted to create a "breeder reactor" an energy generating nuclear reactor that actually produces more fissile material than it consumes (by essentially turning material around it radioactive). The concept was popular in the 1970s but for the most part has been abandoned thanks to modern technology and geologic finds that make mining uranium more cost-efficient. The breeder reactor concept was described by the Department of Energy in 1971 as follows: A breeder is a reactor that produces more fuel than it consumes If the breeder can be used in a nuclear power plant, it can provide the heat needed for the generation of electricity and simultaneously produce an excess of fissionable material that can be used to fuel other plants. The answer to this apparent contradiction is that breeder reactors do not give "something for nothing", but produce usable fissionable material from comparatively useless fertile material at a greater rate than the original fuel in the reactor is consumed in the fissioning process. The obvious question is how would an adolescent working out of his mother's potting shed acquire fissile material to play around with? This is where Hahn's myopic focus and determination really shined: Many household products (and even more in the 1990s) contain radioactive material, but the problem is scale. Hahn exploited several commonly found products and used his knowledge of chemistry to extract and concentrate it to create radioactivity at levels "not found in nature." Early on, one common source of Hahn's radioactive material came from household smoke detectors, which contain extremely small amounts of the radioactive isotope americium-241 as part of the mechanism that detects smoke. He "contacted smoke-detector companies and claimed that he needed a large number of the devices for a school project." To obtain the radioactive isotope thorium-232, Hahn recalled a fact he had learned as an Eagle Scout: that the mantle of gas lanterns contains traces of the radioactive material. So he purchased "thousands of lantern mantles from surplus stores and, using the blowtorch, reduced them into a pile of ash." This method produced radiation levels "9,000 times the level found in nature and 170 times the level that requires [Nuclear Regulatory Commission] licensing." Radium-226, he learned, was found in the paint of antique luminescent clocks. Hahn was able to find an antique can of the mildly radioactive paint in a clock at a nearby antique store, which he used to isolate the isotope for experiments. Tritium, he found, was used as a component of glow-in-the-dark gun and bow sights, which he repeatedly purchased and returned as part of a scheme to collect the material. Hahn "removed the tritium contained in a waxy substance inside the sights, and then, using a variety of pseudonyms, returned the sights to the store or manufacturer for repaireach time collecting another tiny quantity of tritium." These purchases were not the only instances in which Hahn employed subterfuge to obtain radioactive material. Claiming to be a professor, he once wrote to a Czechoslovakian firm that sells uranium to commercial and university buyers, obtaining a few samples of material which contained uranium-235 and uranium-238. "Ignoring any thought of safety," as Harper's described it, he attempted to build a reactor using the radioactive material he had collected over the years, using a schematic in his father's college chemistry textbook as his guide: [Hahn] took the highly radioactive radium and americium out of their respective lead casings and, after another round of filing and pulverizing, mixed those isotopes with beryllium and aluminum shavings, all of which he wrapped in aluminum foil. What were once the neutron sources for his guns became a makeshift "core" for his reactor. He surrounded this radioactive ball with a "blanket" composed of tiny foil-wrapped cubes of thorium ash and uranium powder, which were stacked in an alternating pattern with carbon cubes and tenuously held together with duct tape. While he never achieved the critical mass necessary for a self-sustaining reaction, Hahn certainly appeared to have accomplished the creation of some new fissile material: [Hahn] monitored his "breeder reactor" with his Geiger counter. "It was radioactive as heck," he says. "The level of radiation after a few weeks was far greater than it was at the time of assembly. I know I transformed some radioactive materials. Even though there was no critical pile, I know that some of the reactions that go on in a breeder reactor went on to a minute extent" When his Geiger counter began picking up radiation five doors down from his mom's house, David decided that he had "too much radioactive stuff in one place" and began to disassemble the reactor. He placed the thorium pellets in a shoebox that he hid in his mother's house, left the radium and americium in the shed, and packed most of the rest of his equipment into the trunk of the Pontiac 6000. All of these events took place before the end of 1994, and perhaps they would have remained a secret to this day if Hahn had not stashed the remains of his nuclear reactor in that Pontiac. On 31 August 1994, police responded to complaints that Hahn was in a residential neighborhood "stealing tires from a car." In their discussion with Hahn, the police ended up performing a search of the car and found: When they opened the trunk they discovered a toolbox shut with a padlock and sealed with duct tape for good measure. The trunk also contained over fifty foil-wrapped cubes of mysterious gray powder, small disks and cylindrical metal objects, lantern mantles, mercury switches, a clock face, ores, fireworks, vacuum tubes, and assorted chemicals and acids. The police were especially alarmed by the toolbox, which David warned them was radioactive and which they feared was an atomic bomb. The discovery of the radioactive contents of Hahn's trunk "automatically triggered the Federal Radiological Emergency Response Plan, and state officials soon were embroiled in tense phone consultations with the DOE, EPA, FBI, and NRC." After examining his mother's property (which she had cleansed of the most radioactive material in advance of law enforcement searches of the property for fear she would lose her home), authorities decided that the site was to be an EPA clean-up operation: A Superfund cleanup took place between June 26 and 28 at a cost of about $60,000. After the moon-suited workers dismantled the potting shed with electric saws, they loaded the remains into thirty-nine sealed barrels placed aboard a semitrailer bound for Envirocare, a dump facility located in the middle of the Great Salt Lake Desert. There, the remains of [Hahn's] experiments were entombed along with tons of low-level radioactive debris from the government's atomic-bomb factories, plutonium-production facilities, and contaminated industrial sites. Hahn fell into a deep depression following this episode, according to Harper's, which was likely exacerbated by his mother's suicide in 1996. He enlisted in the armed forces and spent four years in the U.S. Navy followed by some time in the Marines Corps before returning to his home state of Michigan. In 2007 the FBI investigated claims that Hahn was storing radioactive material in his apartment. In an interview with the FBI, Hahn described his honorable discharge from the military and his struggles with paranoid schizophrenia in the years following his return home: Hahn advised that prior to joining the Navy in May, 1997, he got into trouble for stealing tires and rims from a vehicle. Hahn stated he was in the Navy for approximately five and a half years as a internal communication specialist as well as various other positions. Hahn said he then received his associates from Macomb Community College for Applied Science in Criminal Justice. Hahn advised that he then enlisted in the Marines in 2004. Hahn stated he was a truck driver for approximately a year and a half before he was honorably discharged. Hahn said after a few months living with his [REDACTED], Hahn moved to his current residence. Hahn advised that he does not currently have a job. Hahn stated he is on disability because he was diagnosed with paranoid schizophrenia. Hahn said he also has radiation poisoning from his prior contact with radioactive substances. Hahn advised that he is compliant with all his medications most of the time. Hahn stated he occasionally drinks while he is on his medications. Hahn ran into trouble with the law for stealing smoke detectors in 2007 as well, and he experienced repeated drug-related incidents in the years following. He died on 27 September 2016 at the age of 39, a death which was the result of alcohol poisoning, his father said: Citing a toxicology and autopsy report, Kenneth Hahn said his son was found with a dangerous level of blood alcohol content, 0.404, late in the evening on September 26, 2016 Prior to his death, [Kenneth] Hahn accompanied his son to the Veterans Administration hospital for quarterly routine checkups. Medical staff there found no lingering ill effects from the earlier radiation exposure.
