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.

angry tapir quotes a report from Computerworld: Scientists in South Korea have developed solar cells thin enough they can be bent around a pencil. The cells could help usher in the use of solar energy in small portable gadgets where space is at a premium. The cells are fabricated onto a flexible substrate that is just a micrometer thick -- one-half to one-quarter the thickness of other "thin" solar cells and hundreds of times thinner than conventional cells. [The team at the Gwangju Institute of Science and Technology in South Korea managed to reduce the thickness by directly attaching the cells to the substrate without the use of an adhesive. They were stamped onto the substrate and then cold welded, a process that binds two materials together through pressure, not heat. The scientists tested the cells and discovered they can almost be folded in half -- wrapped around a radius as small as 1.4 millimeters. A paper describing the work was published on Monday in Applied Physics Letters, a journal of the American Institute of Physics.]

schwit1 quotes a report from ScienceAlert: Two scientists have come up with a depressing new hypothesis that attempts to explain why cancer is so hard to stop. Maybe, they suggest, cancer's not working against us. Maybe the disease is actually an evolutionary 'final checkpoint' that stops faulty DNA from being passed down to the next generation. To be clear, this is just a hypothesis. It hasn't been tested experimentally, and, more importantly, no one is suggesting that anyone should die of cancer. In fact, it's quite the opposite -- the researchers say that this line of thinking could help us to better understand the disease, and come up with more effective treatment strategies, like immunotherapy, even if a cure might not be possible. So let's step back a second here, because why are our bodies trying to kill us? The idea behind the paper is based on the fact that, in the healthy body, there are a whole range of inbuilt safeguards, or 'checkpoints,' that stop DNA mutations from being passed onto new cells. One of the most important of these checkpoints is apoptosis, or programmed cell death. Whenever DNA is damaged and can't be fixed, cells are marked for apoptosis, and are quickly digested by the immune system -- effectively 'swallowing' the problem. No mess, no fuss. But the new hypothesis suggests that when apoptosis -- and the other safeguards -- don't work like they're supposed to, cancer just might be the final 'checkpoint' that steps in and gets rid of the rogue cells before their DNA can be passed on... by, uh, killing us, and removing our genetic material from the gene pool.

MarkWhittington quotes a report from Examiner: Ever since the EmDrive entered the news about a year or so ago, it has sparked considerable controversy. The device is alleged to work by using microwaves that produce, in some fashion as yet unknown to science, thrust. Many scientists suggest that the EM drive is impossible as it violates known physics. However, a number of tests conducted in Great Britain, Germany, China, and at NASA's Eagleworks at the Johnson Spaceflight Center have resulted in thrust that cannot, as yet, be explained by experimental error. The International Business Times reported that a Finnish scientist has published an article in a peer-reviewed science journal with a possible explanation as to how the drive works. International Business Times writes, "A new peer-reviewed paper on the EmDrive from Finaland states that the controversial electromagnetic space propulsion technology does work due to microwaves fed into the device converting photons that leak out of the closed cavity, producing an exhaust. The research, entitled "On the exhaust of electromagnetic drive," is published in the journal AIP Advances 6 and is the brainchild of Dr Arto Annila, a physics professor at the University of Helsinki; Dr Erkki Kolehmainen, an organic chemistry professor at the University of Jyvaskyla; and Patrick Grahn, a multiphysicist at engineering software firm Comsol."

An anonymous reader writes from a report via USA Today: The World Health Organization reports that drinking coffee, tea and other beverages at temperatures hotter than 149 degrees Fahrenheit may lead to cancer of the esophagus. These hot beverages can injure cells in the esophagus and lead to the formation of cancer cells, said Mariana Stern, an associate professor of preventative medicine and urology at the University of Southern California's Keck School of Medicine. But scientists did say that if you drink coffee at cooler temperatures, it is not only safe but it may decrease of the risk of liver cancer by 15%, according to research published in Lancet Oncology. Previously, the International Agency for Research on Cancer ruled coffee was a "possible carcinogenic" in 1991. The research involved Stern and 22 other scientists from 10 countries, who examined about 1,000 studies on more than 20 types of cancer.

sackvillian writes: Many Slashdotters are aware of the infamous thalidomide birth defect crisis. What might come as a surprise is the incredible success that thalidomide and some analogs have recently found as treatments for cancer, ulcers, lupus, and more. In fact, thanks in part to their success, there's a growing research movement that's attempting to treat cancer with other existing drugs that are commonly used for totally unrelated conditions. Drugs as common as aspirin, which is in the early stages of a clinical trial that will involve over 10,000 cancer patients, are being used. As described in the article written by The Guardian, at least one major international collaboration has taken this approach: The Repurposing Drugs in Oncology (ReDO) project. However, as most of the drugs are long since off-patent, researchers are having to be creative in obtaining funding for their work. Last week, Vice President Joe Biden unveiled a public database for clinical data on cancer that aims to help researchers and doctors better tailor new treatments to individuals.

An anonymous reader writes: Walgreens has announced that it's terminating its partnership with blood-testing startup Theranos. All 40 of the "Theranos Wellness Centers" in Walgreen's Arizona drugstores will be shut down immediately, closing what has been a primary link between Theranos and would-be consumers, and further wounding the troubled startup's revenue. "In light of the voiding of a number of test results, and as the Centers for Medicare and Medicaid Services (CMS) has rejected Theranos' plan of correction and considers sanctions, we have carefully considered our relationship with Theranos and believe it is in our customers' best interests to terminate our partnership," said Walgreens senior vice president Brad Fluegel in a press statement.

schwit1 quotes a report from The Telegraph: Multiple sclerosis patients who were severely disabled are walking, working and even downhill skiing again following a breakthrough therapy which completely destroys, then rebuilds, the immune system. The trial, which is the first in the world to show complete long-term remission from the debilitating disease has been hailed by experts as "exciting" "unprecedented," and "close to curative." Although it is unclear what causes MS it is thought that the immune system attacks the protective coating which surrounds nerve cells in the brain and spinal cord leading to inflammation, pain, disability and in severe cases, early death. [The new technique, which is a treatment usually used to fight leukemia, involves using chemotherapy to entirely eradicate the damaged immune system, before rebooting it with a transfusion of bone marrow cells. Out of the 24 patients who were given the treatment at least seven years ago, the majority have seen significant improvements. 70 per cent of patients saw a complete stop to the progression of the disease, while 40 per cent saw a reversal in symptoms such as vision loss, muscle weakness and balance loss.] Last week, it was reported that a wheelchair-bound stroke victim was able to walk again after an "unprecedented" stem cell trial at Stanford.

An anonymous reader writes: After it was reported three weeks ago that scientists have held a secret meeting to consider creating a synthetic human genome, the participants of that meeting have officially published their plans. They announced a plan to launch a project that would radically reduce the cost of synthesizing human genomes -- a revolutionary development in biotechnology that could enable technicians to grow human organs for transplantation. The Washington Post reports: "The announcement, published Thursday in the journal Science, is the latest sign that biotechnology is going through a rapidly advancing but ethically fraught period. The promoters of synthetic genomes envision a project that would eventually be on the same scale as the Human Genome Project of the 1990s, which led to the sequencing of the first human genomes. The difference this time would be that, instead of 'reading' genetic codes, which is what sequencing does, the scientists would be 'writing' them. They have dubbed this the 'Genome Project-write.'"

New submitter maharvey writes: A woman in Pennsylvania has contracted a strain of E Coli that is unaffected by all known legal antibiotics, including the antibiotics of last resort. We have had bacteria that were resistant, but this is the first bacteria that is completely immune. Such bacteria were known in China, but since the woman has not traveled recently it means she contracted it in the wild in the USA. This is a major step toward the terrifying post-antibiotic world.

Trailrunner7 quotes a report from onthewire.io: The FBI is working to keep information contained in a key biometric database private and unavailable, even to people whose information is contained in the records. The database is known as the Next Generation Identification System (NGIS), and it is an amalgamation of biometric records accumulated from people who have been through one of a number of biometric collection processes. That could include convicted criminals, anyone who has submitted records to employers, and many other people. The NGIS also has information from agencies outside of the FBI, including foreign law enforcement agencies and governments. Because of the nature of the records, the FBI is asking the federal government to exempt the database from the Privacy Act, making the records inaccessible through information requests. From the report: "The bureau says in a proposal to exempt the database from disclosure that the NGIS should be exempt from the Privacy Act for a number of reasons, including the possibility that providing access 'could compromise sensitive law enforcement information, disclose information which would constitute an unwarranted invasion of another's personal privacy; reveal a sensitive investigative technique; could provide information that would allow a subject to avoid detection or apprehension; or constitute a potential danger to the health or safety of law enforcement personnel, confidential sources, and witnesses.'" RT released a similar report on the matter.

HughPickens.com writes: Smallpox was one of the most devastating diseases humanity has ever faced, killing more than 300 million people in the 20th century alone. But thanks to the most successful global vaccination campaign in history, the disease was completely eradicated by 1980. By surrounding the last places on earth where smallpox was still occurring -- small villages in Asia and Africa -- and inoculating everyone in a wide circle around them, D. A. Henderson and the World Health Organization were able to starve the virus of hosts. Smallpox is highly contagious, but it is not spread by insects or animals. When it is gone from the human population, it is gone for good. But Errol Moris writes in the NYT that Henderson didn't really eliminate smallpox. In a handful of laboratories around the world, there are still stocks of smallpox, tucked away in one freezer or another. In 2014 the CDC announced that vials containing the deadly virus had been discovered in a cardboard box in a refrigerator located on the National Institutes of Health (NIH) campus in Bethesda, Maryland. How can you say it's eliminated when it's still out there, somewhere? The demon in the freezer.

Some scientists say that these residual stocks of smallpox should not be destroyed because some ruthless super-criminal or rogue government might be working on a new smallpox, even more virulent than existing strains of the virus. We may need existing stocks to produce new vaccines to counteract the new viruses. Meanwhile, opponents of retention argue that there's neither need nor practical reason for keeping the virus around. In a letter to Science Magazine published in 1994, the Nobel laureate David Baltimore wrote, "I doubt that we so desperately need to study smallpox that it would be worth the risk inherent in the experimentation." It all comes down to the question of how best to protect ourselves against ourselves. Is the greater threat to humanity our propensity for error and stupidity, or for dastardly ingenuity?

An anonymous reader writes from a report via The New York Times, summarized by Gizmodo: Earlier this week, over a hundred scientists, lawyers, and entrepreneurs held a secret meeting to discuss the possibility of creating a synthetic human genome. Creating a synthetic human genome differs from gene editing as scientists would use chemicals to manufacture all the DNA contained in human chromosomes, instead of patching a gene here and there. Synthetic genomics, unlike genetic modifications, in that it doesn't use naturally occurring genes. Instead, it relies on the custom-designed base pair series. Currently, customers view synthetic genomics as a way to build novel microbes and animals, but with humans it raises the prospect of custom-designed humans, without any parents. George Church, a professor of genetics at Harvard Medical School and one of the organizers of the proposed project, says the characterization was a misunderstanding, and that the project was aimed to generally improve the ability to synthesize long strands of DNA, which could be applied to various types of animals, plants and microbes. "They're painting a picture which I don't think represents the project," Dr. Church said in an interview. The project was initially called "HGP2: The Human Genome Synthesis Project." However, the name was later changed to "HGP-Write: Testing Large Synthetic Genomes In Cells." Why the change? Because the original headline was suppose to be headline-grabbing, or so they say.

An anonymous reader writes: According to Reuters, "Using a culture method previously tested to grow mouse embryos outside of a mother, the teams were able to conduct almost hour by hour observations of human embryo development to see how they develop and organize themselves up to day 13."

Brave new world, here we come From the report: "The work, covered in two studies published on Wednesday in the journal Nature and Nature Cell Biology, showed how the cells that will eventually form the human body self-organize into the basic structure of a post-implantation human embryo. As well as advancing human biology expertise, the knowledge gained from studying these developments should help to improve in-vitro fertilization (IVF) treatments and further progress in the field of regenerative medicine, the researchers said. But the research also raises the issue of an international law banning scientists from developing human embryos beyond 14 days, and suggests this limit may have to be reviewed. 'Longer cultures could provide absolutely critical information for basic human biology,' said researcher Zernicka-Goetz. 'But this would of course raise the next question - of where we should put the next limit.'"

Josiah Zayner writes: Arielle Duhaime-Ross at The Verge followed Dr. Josiah Zayner, a former Scientist at NASA turned BioHacker, as he attempted the first ever full-body microbiome transplant. She writes "Over the course of the next four days, Zayner would attempt to eradicate the trillions of microbes that lived on and inside his body -- organisms that helped him digest food, produce vitamins and enzymes, and protected his body from other, more dangerous bacteria. Ruthlessly and methodically, he would try to render himself into a biological blank slate. Then, he would inoculate himself with a friend's microbes -- a procedure he refers to as a 'microbiome transplant.'".

Sarah Knapton, writing for The Telegraph: A groundbreaking trial to see if it is possible to regenerate the brains of dead people, has won approval from health watchdogs. A biotech company called BioQuark in the U.S. has been granted ethical permission to recruit 20 patients who have been declared clinically dead from a traumatic brain injury, to test whether parts of their central nervous system can be brought back to life. Scientists will use a combination of therapies, which include injecting the brain with stem cells and a cocktail of peptides, as well as deploying lasers and nerve stimulation techniques which have been shown to bring patients out of comas. The trial participants will have been certified dead and only kept alive through life support. They will be monitored for several months using brain imaging equipment to look for signs of regeneration, particularly in the upper spinal cord -- the lowest region of the brain stem which controls independent breathing and heartbeat.

An anonymous reader writes: For the first time data may show that a human being has been successfully rejuvenated by gene therapy, claims Bioviva USA. "In September 2015, then 44 year-old CEO of Bioviva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities." Bypassing America's FDA, the controversial therapies were described by the MIT Technology Review as "do-it-yourself medicine," saying it "raises ethical questions about how quickly such treatments should be tested in people and whether they ought to be developed outside the scrutiny of regulators." "The treatment was originally intended to demonstrate the safety of the latest generation of the therapies," reports Bioviva's web site. "But if early data is accurate, it is already the world's first successful example of telomere lengthening via gene therapy in a human individual."

An anonymous reader writes: The European Organization for Nuclear Research, known as CERN, has released 300 terabytes of collider data to the public. "Once we've exhausted our exploration of the data, we see no reason not to make them available publicly," said Kati Lassila-Perini, a physicist who works on the Compact Muon Solenoid detector. "The benefits are numerous, from inspiring high school students to the training of the particle physicists of tomorrow. And personally, as CMS's data preservation coordinator, this is a crucial part of ensuring the long-term availability of our research data," she said in a news release accompanying the data. Much of the data is from 2011, and much of it is from protons colliding at 7 TeV (teraelectronvolts). The 300 terabytes of data includes both raw data from the detectors and "derived" datasets. CERN is providing tools to work with the data which is handy.

An anonymous reader writes: According to the Wall Street Journal, health regulators have proposed pulling the federal license for the company's California laboratory and banning its founder and CEO, Elizabeth Holmes, and company president Sunny Balwani from the blood-testing business for two years. The letter which the WSJ cited in its report found that Theranos had not corrected problems at its lab in Newark, California, and faced possible sanctions as a result. In October 2015, the WSJ reported all but one of Theranos' analyzers in use were off the shelf, and that their tiny samples may not always have been accurate. The company was facing allegations of data manipulation in late December 2015. Earlier this year, U.S. regulators found serious deficiencies at Theranos' laboratory in Newark, California, putting the company's relationship with the Medicare program in danger. Theranos has said that The Centers for Medicare and Medicaid Services (CMS) has not imposed sanctions on its Newark Lab. "Due to the comprehensive nature of the corrective measures we've taken over the past several months, which has been affirmed by several experts, we are hopeful that CMS won't impose sanctions," the company said in an emailed statement. "But if they do, we will work with CMS to address all of their concerns."
