Ahmed Zewail pioneered a technique for using lasers to monitor chemical reactions, which the Royal Swedish Academy of Sciences said sparked "a revolution in chemistry and adjacent sciences." Slashdot reader Provocateur writes, "The Washington Post has the story...citing his prizewinning research in femtochemistry..."

Slashdot covered Zewail's Nobel prize in 1999, as well as his 2001 claim to have resolved Heisenberg's Uncertainty Principle. "Mathematics, mechanics, and chemistry were among the fields that gave me a special satisfaction..." he says in the Post's article, adding "for reasons unknown (to me), my mind kept asking 'how' and 'why.' "

Slashdot reader sciencehabit quotes an article from Science magazine: The National Institutes of Health announced that the agency soon expects to lift a moratorium on funding for controversial experiments that add human stem cells to animal embryos, creating an organism that is part animal, part human. Instead, these so-called chimera studies will undergo an extra layer of ethical review but may ultimately be allowed to proceed.

Although scientists who support such research welcomed the move, some were left trying to parse exactly what the draft policy will mean. It is "a step in the right direction," says Sean Wu, a stem cell researcher at Stanford University in Palo Alto, California, who co-authored a letter to Science last year opposing the moratorium. But "we still don't know what the outcome will be case by case," he adds. However, some see the proposal as opening up research in some areas that had been potentially off-limits.
Experiments could include using animals to grow human organs for transplants, although according to the article, some scientists "worry that the experiments could produce, say, a supersmart mouse."

It's already underway just 364 miles south of Florida, according to the Associated Press. "The first wave of genetically modified mosquitoes were released Wednesday in the Cayman Islands as part of a new effort to control the insect that spreads Zika and other viruses," according to an article shared by Slashdot reader Okian Warrior: Genetically altered male mosquitoes, which don't bite but are expected to mate with females to produce offspring that die before reaching adulthood, were released in the West Bay area of Grand Cayman Island, according to a joint statement from the Cayman Islands Mosquito Research and Control Unit and British biotech firm Oxitec.
"What could possibly go wrong?" asks The Atlantic, citing history's great pest-control fails in Hawaii and Australia. But a similar release is already being considered in the Florida Keys, though Accuweather reports it apparently depends on the results of a November referendum which could also "affect the likelihood of Oxitec trials taking place in other parts of the United States."

Alex Pearlman, reporting for Motherboard: As the biotech revolution accelerates globally, the U.S. could be getting left behind on key technological advances: namely, human genetic modification. A Congressional ban on human germline modification has "drawn new lines in the sand" on gene editing legislation, argues a paper published today in Science by Harvard law and bioethics professor I. Glenn Cohen and leading biologist Eli Adashi of Brown University. They say that without a course correction, "the United States is ceding its leadership in this arena to other nations." Germline gene modification is the act of making heritable changes to early stage human embryos or sex cells that can be passed down to the next generation, and it will be banned in the US. This is different from somatic gene editing, which is editing cells of humans that have already been born. The ban, added by the House of Representatives as a rider to the fiscal year 2016 budget, could have far-reaching implications if it continues to be annually renewed, according to the authors. It "undermines ongoing conversations on the possibility of human germline modification" and also affects "ongoing efforts by the FDA [Food and Drug Administration] to review the prevention of mitochondrial DNA diseases," including some kinds of hearing and vision impairments, among other serious illnesses that tend to develop in young children.

An anonymous reader quotes a report from Reuters: GlaxoSmithKline (GSK) and Google parent Alphabet's life sciences unit are creating a new company focused on fighting diseases by targeting electrical signals in the body, jump-starting a novel field of medicine called bioelectronics. Verily Life Sciences -- known as Google's life sciences unit until last year -- and Britain's biggest drugmaker will together contribute 540 million pounds ($715 million) over seven years to Galvani Bioelectronics, they said on Monday. The new company, owned 55 percent by GSK and 45 percent by Verily, will be based at GSK's Stevenage research center north of London, with a second research hub in South San Francisco. Galvani will develop miniaturized, implantable devices that can modify electrical nerve signals. The aim is to modulate irregular or altered impulses that occur in many illnesses. GSK believes chronic conditions such as diabetes, arthritis and asthma could be treated using these tiny devices, which consist of a electronic collar that wraps around nerves. Kris Famm, GSK's head of bioelectronics research and president of Galvani, said the first bioelectronic medicines using these implants to stimulate nerves could be submitted for regulatory approval by around 2023. GSK first unveiled its ambitions in bioelectronics in a paper in the journal Nature three years ago and believes it is ahead of Big Pharma rivals in developing medicines that use electrical impulses rather than traditional chemicals or proteins.

An anonymous reader quotes a report from CNBC: Theranos CEO Elizabeth Holmes Monday outlined the steps she will take to increase transparency regarding the efficacy of the company's testing methods. Speaking at the conference of the American Association for Clinical Chemistry, Holmes said that Theranos will partner with other institutions "to validate and publish our results." And Holmes' planned presentation includes research conducted under Institutional Review Board-approved protocols. The company also said it intends to submit its results to a publication for peer-review. Holmes' presentation includes a slate of new products such as its miniLab, a robot that can process samples that normally require manual processing in traditional protocols. Theranos seems to be going back to the research and development drawing board, focusing on these new products instead of its much-debated small-volume blood collection technology. Theranos' miniLab is a self-contained laboratory that allows a robot to run a number of tests on samples. The miniLab contains different modules that allow it to conduct a series of tasks that traditionally would require multiple, separate machines. Theranos used its miniLab to run its Zika nucleic acid-amplification-based assay using finger-prick samples the company collected, some in the Dominican Republic. The samples were shipped back to Palo Alto, California, for analysis. Holmes said the results "demonstrate the miniLab's ability to perform automated, integrated molecular testing comparable to methods that require highly-trained personnel."

An anonymous reader quotes a report from Washington Times: Despite the objection of environmental groups, state environmental regulators voted Tuesday to approve new standards that will increase the amount of cancer-causing toxins allowed in Florida's rivers and streams under a plan the state says will protect more Floridians than current standards. The Environmental Regulation Commission voted 3-2 to approve a proposal that would increase the number of regulated chemicals from 54 to 92 allowed in rivers, streams and other sources of drinking water, news media outlets reported. The Miami Herald reports that under the proposal, acceptable levels of toxins will be increased for more than two dozen known carcinogens and decreased for 13 currently regulated chemicals. State officials back the plan because it places new rules on 39 other chemicals that are not currently regulated. The standards still must be reviewed by the U.S. Environmental Protection Agency, but the Scott administration came under withering criticism for pushing the proposal at this time. That's because there are two vacancies on the commission, including one for a commissioner who is supposed to represent the environmental community.

An anonymous reader quotes a report from NPR: About four years ago, Kevin Sinclair inherited an army of clones. "Daisy, Debbie, Denise and Diana," says Sinclair, a developmental biologist at the University of Nottingham in England. "'Sister clones' probably best describes them," Sinclair says. "They actually come from the exactly the same batch of cells that Dolly came from." In an article out Tuesday in the journal Nature Communications, Sinclair and his colleagues write that the ewes' age, along with their strapping health, might be a reason for people to start feeling more optimistic about what cloning can do. Dolly's life did not turn out as scientists in the cloning field hoped it would. She died young -- 6 1/2 -- with a nasty lung virus. "That was really just bad luck," Sinclair says, and had "nothing to do" with the fact that Dolly was a clone. It was a daunting concept for those in the cloning field, because, says Sinclair, "If you're going to create these animals, they should be normal in every respect. They should be just as healthy as any other animal that's conceived naturally. If that is not the case, then it raises serious ethical and welfare concerns about creating these animals in the first place." But, the good health of the 13 clones in the Nottingham herd suggest better prospects for the procedure. Sinclair and his colleagues evaluated the animals' blood pressure, metabolism, heart function, muscles and joints, looking for signs of premature aging. They even fattened them up (since obesity is a risk factor for metabolic problems including diabetes) and gave them the standard tests to gauge how their bodies would handle glucose and insulin. The results? Normal, normal, normal. "There is nothing to suggest that these animals were anything other than perfectly normal," says Sinclair. They had slight signs of arthritis (Debbie in particular), but not enough to cause problems. "If I put them in with a bunch of other sheep, you would never be able to identify them," he says.

Futurist Ray Kurzweil told a Seattle conference specific ways in which technology is already improving our lives. For example, while there's a general perception that the world's getting worse, "What's actually happening is our information about what's wrong in the world is getting better. A century ago, there would be a battle that wiped out the next village, you'd never even hear about it." An anonymous Slashdot reader quotes two of Kurzweil's other interesting insights: "We're only crowded because we've crowded ourselves into cities. Try taking a train trip across the United States, or Europe or Asia or anywhere in the world. Ninety-nine percent of the land is not used... we don't want to use it because you don't want to be out in the boondocks if you don't have people to work and play with. That's already changing now that we have some level of virtual communication..."

[And on the potential of human genomics] "It's not just collecting what is basically the object code of life that is expanding exponentially. Our ability to understand it, to reverse-engineer it, to simulate it, and most importantly to reprogram this outdated software is also expanding exponentially. Genes are software programs. It's not a metaphor. They are sequences of data. But they evolved many years ago, many tens of thousands of years ago..."

the_newsbeagle writes: Iris scanning is increasingly being used for biometric identification because it's fast, accurate, and relies on a body part that's protected and doesn't change over time. You may have seen such systems at a border crossing recently or at a high-security facility, and the Indian government is currently collecting iris scans from all its 1.2 billion citizens to enroll them in a national ID system. But such scanners can sometimes be spoofed by a high-quality paper printout or an image stuck on a contact lens.

Now, new research has shown that post-mortem eyes can be used for biometric identification for hours or days after death, despite the decay that occurs. This means an eye could theoretically be plucked from someone's head and presented to an iris scanner. The same researcher who conducted that post-mortem study is also looking for solutions, and is working on iris scanners that can detect the "liveness" of an eye. His best method so far relies on the unique way each person's pupil responds to a flash of light, although he notes some problems with this approach.

An anonymous reader quotes a report from The Guardian: A team of Chinese scientists will be the first in the world to apply the revolutionary gene-editing technique known as CRISPR on human subjects. Led by Lu You, an oncologist at Sichuan University's West China hospital in Chengdu, China, the team plan to start testing cells modified with CRISPR on patients with lung cancer in August, according to the journal Nature. CRISPR is a game-changer in bioscience; a groundbreaking technique which can find, cut out and replace specific parts of DNA using a specially programmed enzyme named Cas9. Its ramifications are next to endless, from changing the color of mouse fur to designing malaria-free mosquitoes and pest-resistant crops to correcting a wide swath of genetic diseases like sickle-cell anaemia in humans. The Sichuan University trial, it is important to note, does not edit the germ-line; its effects will not be hereditary. What the researchers plan to do is enroll patients with metastatic non-small cell lung cancer, Nature reported, and for whom other treatment options -- including chemotherapy and radiotherapy -- have failed. They will then extract immune cells from the patients' blood and use CRISPR to add a new genetic sequence which will help the patient's immune system target and destroy the cancer. The cells will then be re-introduced into the patients' bloodstream. The Guardian does note that CRISPR was approved for human trials in the U.S., but if it begins on schedule in August the Sichuan University study will beat them to the punch of being the first of its kind.

An anonymous reader writes from a report via Digital Trends: Researchers at Purdue University and the University of Tennessee have found a non-chemical way to extend regular milk's shelf life to around 2-3 weeks, and without affecting the nutrients or flavor. The technology they've developed involves increasing the temperature of milk by just 10 degrees for less than a second, which is well below the 70-degree Celsius threshold needed for pasteurization. That quick heat blast is still able to eliminate more than 99 percent of the bacteria left from pasteurization. "The developed technology uses low temperature, short time (LTST) in a process that disperses milk in the form of droplets with low heat/pressure variation over a short treatment time in conjunction with pasteurization," Bruce Applegate, Purdue's associate professor in the Department of Food Science, explained to Digital Trends. "The resultant product was subjected to a taste panel and participants had equal or greater preference for the LTST pasteurized milk compared to normally pasteurized milk. The shelf was determined to be a minimum of two weeks longer than the standard shelf life from pasteurization alone." As for whether or not this method will make its way to store shelves, it won't in the near future. "Currently an Ohio-based milk processor is using this technology and distributing the milk," Applegate says. "The unit is approved for processing milk in Ohio and distribution nationwide. The product is currently being distributed, however it has not been labeled as extended shelf life milk. Once the commercial application is validated the milk will be labelled with the extended shelf life." Scientists from Duke University believe there may be a large source of hydrogen gas under the ocean, caused by rocks forming from fast-spreading tectonic plates.

HughPickens.com writes: Christopher Ingraham writes in the Washington Post that a new study shows that painkiller abuse and overdose are significantly lower in states with medical marijuana laws and that when medical marijuana is available, pain patients are increasingly choosing pot over powerful and deadly prescription narcotics. The researchers "found that, in the 17 states with a medical-marijuana law in place by 2013, prescriptions for painkillers and other classes of drugs fell sharply compared with states that did not have a medical-marijuana law... In medical-marijuana states, the average doctor prescribed 265 fewer doses of antidepressants each year, 486 fewer doses of seizure medication, 541 fewer anti-nausea doses and 562 fewer doses of anti-anxiety medication. But most strikingly, the typical physician in a medical-marijuana state prescribed 1,826 fewer doses of painkillers in a given year."

[P]ainkiller drug companies "have long been at the forefront of opposition to marijuana reform, funding research by anti-pot academics and funneling dollars to groups, such as the Community Anti-Drug Coalitions of America, that oppose marijuana legalization..."

Biological engineers at a Department of Energy lab "are experimenting with encrypted DNA storage for archival applications." Slashdot reader ancientribe shares an article from Dark Reading: Using this method, the researchers could theoretically store 2.2 petabytes of information in one gram of DNA. That's 200 times the printed material at the Library of Congress... Instead of needing a 15,000 square-foot building to store 35,000 boxes of inactive records and archival documents, Sandia National Laboratories can potentially store information on much less paper, in powder form, in test tubes or petri dishes, or even as a bacterial cell... "Hard drives fail and very often the data can't be recovered," explains Bachand. "With DNA, it's possible to recover strands that are 10,000 to 20,000 years old... even if someone sneezes and the powder is lost, it's possible to recover all the information by just recovering one DNA molecule."

An anonymous reader writes from a report via WIRED: Lab-grown meat appears to be coming to a supermarket near you whether you like it or not. Granted, you have some time before that becomes a reality. Scientists in Belgium and the United States are working on cultured meat substitutes that taste like real meat and cost less than real meat, but don't use as many environmental resources as meat from animals, nor does it involve the slaughtering of animals. They predict such meat substitutes will cost a lot less by the year 2020 when the efficiency of bulk production kicks in. According to a 2014 Pew poll, only 20 percent of Americans would be willing to try cultured meat, while a 2013 survey in Belgium revealed that just 13 percent of 180 subjects knew what cultured meat was. Also, vegetarians surveyed perceived man-made meat to be unhealthy and unfavorable. However, once respondents were told how the meat is grown, most said they might try it. When educated about the environmental benefits, the number of people who were willing to try it nearly doubled. A poll from The Vegan Scholar found that lab-grown meat was much more appealing to vegetarians than to vegans. Similar Reddit and SurveyMonkey polls have come to similar conclusions, but it's important to note that none of these polls were peer-reviewed. Researchers have suggested that the media greatly overestimates the importance of vegetarian and vegan opinions on lab-grown meat. Given the lack of large surveys determining the public's opinion on lab-grown meat, we thought we would pose the question to Slashdotters: Would you eat lab-grown meat?

Slashdot reader schwit1 quotes an article from the New York Times: Something strange is going on in medicine. Major diseases, like colon cancer, dementia and heart disease, are waning in wealthy countries, and improved diagnosis and treatment cannot fully explain it...it looks as if people in the United States and some other wealthy countries are, unexpectedly, starting to beat back the diseases of aging. The leading killers are still the leading killers -- cancer, heart disease, stroke -- but they are occurring later in life, and people in general are living longer in good health.
The Times cites one researcher's pet theory that the cellular process of aging itself may be gradually changing in humans' favor.

An anonymous reader quotes a report from Engadget: The Wall Street Journal reports U.S. regulators have devised to ban the owners and operators of Theranos from running a lab for two years. That includes CEO and founder Elizabeth Holmes, as confirmed by a press release issued tonight. The Centers for Medicare and Medicaid Services (CMS) revoked the lab's Clinical Laboratory Improvement Amendments (CLIA) certificate and imposed a civil money penalty for an unspecified amount. The ban does not take effect for 60 days, however Theranos says it will not do any testing at the Newark, CA lab CMS investigated, and instead will serve customers from its lab in Arizona. Elizabeth Holmes wrote: "We accept full responsibility for the issues at our laboratory in Newark, California, and have already worked to undertake comprehensive remedial actions. Those actions include shutting down and subsequently rebuilding the Newark lab from the ground up, rebuilding quality systems, adding highly experienced leadership, personnel and experts, and implementing enhanced quality and training procedures. While we are disappointed by CMS' decision, we take these matters very seriously and are committed to fully resolving all outstanding issues with CMS and to demonstrating our dedication to the highest standards of quality and compliance."

An anonymous reader writes: Harvard researchers report in the journal Science this week that they've built a "bio-inspired swimming robot that mimics a ray fish [and] can be guided by light." The robot's body consists of "a cast elastomer body with a skeleton of gold, along with a single layer of carefully aligned muscle fibers harvested from neonatal rat hearts." The fibers were genetically modified to respond to pulses of blue light and structured along the body of the robot such that contractions result in a repetitive undulating motion, propelling the robot forward. "About 200,000 live rat heart cells form the muscle layer that powers the robot, which has a body 16.3 mm long and weighs just over 10 grams," reports IEEE. "At full tilt, it can swim at a speed of 3.2 mm/s, which isn't bad for such a tiny thing." You can watch the video that shows the robot being led through a 250 mm long obstacle course.

An anonymous reader quotes a report from Phys.Org: Researchers from KU Leuven have now built a very sensitive electronic nose with metal-organic frameworks (MOFs). "MOFs are like microscopic sponges," postdoctoral researcher Ivo Stassen explains. "They can absorb quite a lot of gas into their minuscule pores." "We created a MOF that absorbs the phosphonates found in pesticides and nerve gases. This means you can use it to find traces of chemical weapons such as sarin or to identify the residue of pesticides on food. This MOF is the most sensitive gas sensor to date for these dangerous substances. Our measurements were conducted in cooperation with imec, the Leuven-based nanotechnology research centre. The concentrations we're dealing with are extremely low: parts per billion -- a drop of water in an Olympic swimming pool -- and parts per trillion." The chemical sensor can easily be integrated into existing electronic devices, Professor Rob Ameloot adds. "You can apply the MOF as a thin film over the surface of, for instance, an electric circuit. Therefore, it's fairly easy to equip a smartphone with a gas sensor for pesticides and nerve gas." Professor Ameloot continues, "MOFs can measure very low concentrations, so we could use them to screen someone's breath for diseases such as lung cancer and MS in an early stage. Or we could use the signature scent of a product to find out whether food has gone bad or to distinguish imitation wine from the original. This technology, in other words, offers a wide range of perspectives."

The New York Times reports: More than 100 Nobel laureates have a message for Greenpeace: Quit the G.M.O.-bashing. Genetically modified organisms and foods are a safe way to meet the demands of a ballooning global population, the 109 laureates wrote in a letter posted online and officially unveiled at a news conference on Thursday in Washington, D.C...

"Scientific and regulatory agencies around the world have repeatedly and consistently found crops and foods improved through biotechnology to be as safe as, if not safer than those derived from any other method of production," the group of laureates wrote. "There has never been a single confirmed case of a negative health outcome for humans or animals from their consumption. Their environmental impacts have been shown repeatedly to be less damaging to the environment, and a boon to global biodiversity."
Slashdot reader ArmoredDragon writes: As an echo to that comment, one of the key benefits of GMO is increased crop yield, which means a reduced need for deforestation to make way for farmland. GMO food such as Golden Rice, which improves the micronutrient content of rice, and Low Acrylamide Spuds, which are potatoes engineered to have reduced carcinogen content compared to their natural counterparts, can possibly solve many health problems that are inherent with consuming non-GMO produce. And for those concerned about patent-related issues, many of these patents have recently expired, which means anybody can freely grow them and sell the seeds without the need to pay any royalties.
