But medical experts have warned this does not mean China’s prediction of the epidemic ending in April is accurate. “I know that people are working very hard getting a vaccine together. People are saying that maybe there will be one available by the summer.” (AFP via Getty Images) Around 300 members of staff of Singapore’s largest bank, DBS, have been evacuated after one employee contracted coronavirus, according to the BBC. Brighton GP Catriona Greenwood contracted coronavirus at a chalet in the French Alps last week, believed to have caught it from a so-called super spreader, Steve Walsh. He passed the virus onto 11 people after catching it in Singapore at a conference. Business Steve Walsh, who contracted the illness on a work visit to Singapore before passing it to others on a skiing trip in France, left Guys and St Thomas’ hospital today. He is no longer contagious, according to the NHS.

(Photo by Matt Miller/KTOO)For any Juneau gardeners buying and taking home trees this spring, master gardener Ed Buyarski suggests keeping the bare roots moist until the actual planting.Buyarski had a variety of tips for tree planting during Gardentalk on KTOO’s “Morning Edition” program.“Trees don’t grow deep. Nothing grows deep roots here. Even the huge spruce and hemlock trees don’t grow more than 3 feet deep,” Buyarski said. “Really, we’re better off making a wide area. Dig your hole perhaps a foot to foot and a half deep at most, but wider (by) loosening up the existing soil.”Loosened soil will allow the tree’s roots to spread out.For grafted trees, keep the grafted portion above the soil when you plant it.Mix in soil amendment or compost into the hole and don’t forget to water your newly planted tree. Stake up the tree so that it can establish its roots, and keep the weed wacker away. Spread mulch around the tree to keep the weeds down, but not right up to the trunk.It’s a madhouse!Juneau’s annual plant and garden sale runs 9 a.m. to noon Saturday at the Safeway parking lot.

NIH rejects petition to override patent on pricey prostate cancer drug

first_imgHowever, the NIH denied the petition because there was no information to suggest that Xtandi is or will be in short supply, according to a letter sent on Monday by NIH Director Dr. Francis Collins to Knowledge Ecology International, one of the consumer groups. The agency, which has rarely granted such petitions, noted that the litmus test used in one previous case was whether there were sufficient supplies of the medicine for which a petition was sought. About the Author Reprints NIH Director Dr. Francis Collins Paul Morigi/Getty Images Ed Silverman PharmalotNIH rejects petition to override patent on pricey prostate cancer drug Please enter a valid email address. Leave this field empty if you’re human: At the time, Burwell noted such decisions are made on a case-by-case basis. The NIH previously considered using its march-in authority concerning drug pricing in 2004 and 2013, but determined statutory requirements were not met. Two of those instances involved the Norvir AIDS medicine that was marketed by Abbott Laboratories — now owned by AbbVie — and the Xalatan glaucoma treatment sold by Pfizer.In response, several lawmakers, including presidential aspirant Bernie Sanders, said they would seek a hearing about NIH use of march-in rights, but that never took place. Privacy Policy [email protected] NIH asked to fight price gouging by overriding drug patents Tags cancerdrug pricesNIH After five months of deliberation, the US National Institutes of Health on Monday rejected a request by several consumer groups to override the patent on a prostate cancer drug because the medicine is more expensive in the United States than elsewhere. And one of the consumer groups plans to seek an appeal.Last January, the groups petitioned the NIH to take this step, which is known as a march-in right, to help US patients because federally funded research was used to create Xtandi. The drug is sold by Astellas Pharma and has an average wholesale price in the United States of more than $129,000, about two to four times more than what other high-income countries are paying, according to the consumer groups.Under federal law, a march-in right allows an agency that funds private research to require a drug maker to license its patent to another party in order to “alleviate health and safety needs which are not being reasonably satisfied” or when the benefits of a drug are not available on “reasonable terms.” The drug was developed at the University of California, Los Angeles, with grants from NIH and the US Department of Defense. The school licensed the drug to Medivation, which struck a marketing deal with Astellas.advertisementcenter_img Related: The consumer group plans to submit an appeal to US Secretary of Health and Human Services Sylvia Burwell and said it will base its appeal on the NIH’s “flawed legal rationale” about the use of march-in rights and “its lack of analysis concerning its refusal to use a royalty-free license.” The group added that it plans to refile this case after a new president takes office next year if the HHS declines its appeal.As part of its effort, Knowledge Ecology two months ago solicited Biolyse, a small Canadian drug company, to make Xtandi. The drug maker maintained it could supply a version for $3 per 40-milligram tablet, compared with the $69.41 that Medicare paid in 2014. Biolyse hoped to be able to supply its version in three years. We left word with a company spokesman and will pass along any reply.An Astellas spokesman wrote us to say that the company is “pleased that the NIH has concluded that Xtandi is broadly available to patients, and we are committed to continuing our work with our diverse stakeholders to provide patients with affordable access to our medicines.”The rejection is not a surprise, though.Two months ago, the Obama administration rejected a request from dozens of congressional Democrats, who call themselves the Affordable Drug Pricing Task Force, to develop guidelines that would require drug makers to license their patents and put a lid on “price gouging.” They argued the NIH should be more aggressively granting march-in rights in light of the high price of medicines. @Pharmalot Newsletters Sign up for Pharmalot Your daily update on the drug industry. In a statement, the consumer groups argued the NIH “did not evaluate evidence provided that Astellas charges US residents prices that are far higher than those available to non-US consumers, and that price discrimination against US residents is not consistent with making the product ‘available to the public on reasonable terms,’” as required by federal law.advertisement Related: Pharmalot Columnist, Senior Writer Ed covers the pharmaceutical industry. They also maintained the NIH failed to address evidence that “the unreasonably high price for Xtandi limits patient access, places the drugs on restrictive formularies, causes strain to health care budgets, and requires patients to pay unreasonably high coinsurance and copayments,” all of which justify the use of march-in rights.They added that the NIH ignored its ability to issue a nonexclusive, royalty-free license to allow Xtandi to be manufactured for use by the federal government. Knowledge Ecology legal and policy counselor Andrew Goldman said there is no precondition about supplies and the NIH is wrong to assert that there is no limit on “excessive pricing” in order to grant a march-in right.“This is contrary to the legislative intent of the law, and sends a terrible signal about the government’s willingness to confront the high drug prices through available legal mechanisms,” he said.

ACTCOSS welcomes steps to help Canberrans find lower retail electricity prices

first_imgACTCOSS welcomes steps to help Canberrans find lower retail electricity prices The ACT Council of Social Service (ACTCOSS) has today welcomed the announcement by ACT Chief Minister, Andrew Barr MLA, and Minister for Water, Energy and Emissions, Shane Rattenbury MLA, of legislation requiring ACT electricity retailers to use a common reference price and to inform their customers if a better deal is available.Dr Emma Campbell, ACTCOSS CEO, said: “For most people, comparing electricity offers is a difficult, confusing, and time-consuming process. ACTCOSS welcomes the announcement of legislation that will increase transparency on the part of electricity retailers and make it easier for consumers to compare electricity offers and determine if they are getting the best deal.“These new rules will benefit all Canberrans, but particularly those facing income stress or other engagement barriers, such as time restrictions due to caring, digital exclusion, limited English language proficiency and other complex life circumstances. Energy justice requires that low-income and vulnerable consumers have ready access to electricity at a manageable cost. People should not be forced to spend many hours navigating opaque information to access an essential service at a fair price.“ACTCOSS is pleased to see our advocacy reflected in today’s announcement. ACTCOSS has made submissions to the Independent Competition and Regulatory Commission (ICRC) and directly to the ACT Government advocating for measures to improve the transparency and comparability of electricity prices in the ACT.“While we welcome the steps currently being taken, ACTCOSS is keen to ensure that they do not result in a perverse outcome for consumers. We want to ensure that costs of compliance with these measures are not passed from electricity retailers to customers in a way that negates any customer benefit derived.“It is important to note that these rules alone are not enough to ensure energy justice in the ACT.“ACTCOSS calls on the ACT Government to ensure the Utilities Concession is adequate; to provide continued funding of the Utilities Hardship Fund; to permanently extend eligibility for Utilities Concession to asylum seekers who are ACT Services Access Card holders; and to explore options to support the broader cohort of vulnerable energy consumers in the ACT who are not currently eligible for the Utilities Concession and/or the Utilities Hardship Fund.“ACTCOSS welcomes changes that will increase the accountability and responsibility of electricity retailers, and provide consumers with straightforward, easy-to-action information,” Dr Campbell concluded.ACTCOSS advocates for social justice in the ACT and represents not-for-profit community organisations. /Public Release.

How ideas go viral in academia

first_imgShare Share via TwitterShare via FacebookShare via LinkedInShare via E-mail Published: Nov. 6, 2018 • By Daniel Strain Students attend a computer science class at CU Boulder. (Credit: Glenn Asakawa/CU Boulder) Categories:Health & SocietyNews Headlines How ideas move through academia may depend on where those ideas come from—whether from big-name universities or less prestigious institutions—as much as their quality, a recent study from CU Boulder suggests. The new research borrows a page from epidemiology, exploring how ideas might flow from university to university, almost like a disease. The findings from CU Boulder’s Allison Morgan and her colleagues suggest that the way that universities hire new faculty members may give elite schools an edge in spreading their research to others.Key takeawaysA small number of universities have trained the majority of tenure track faculty in computer science in the U.S. and Canada.That bias may give elite universities an edge in spreading their ideas from university to university—even when those ideas aren’t that good.The good news: great ideas can still catch fire in academia, no matter where they come from.In particular, the team simulated how ideas might spread out faster from highly-ranked schools than from those at the bottom of the pile—even when the ideas weren’t that good. The results suggest that academia may not function like the meritocracy that some claim, said Morgan, a graduate student in the Department of Computer Science. She and her colleagues began by drawing on a dataset, originally published in 2015, that described the hiring histories of more than 5,000 faculty members in 205 computer science programs in the U.S. and Canada. That dataset revealed what might be a major power imbalance in the field—with a small number of universities training the majority of tenure track faculty across both countries. “This paper was really about investigating the implications of the imbalance,” Morgan said. “What does it mean if the elite institutions are producing the majority of the faculty who are, in turn, training the future teachers in the field?”Academic roadmapTo answer that question, the researchers turned the 2015 dataset into a network of connected universities. If a university placed one of its PhD students in a job at another school, then those two schools were linked. The resulting “roadmap” showed how faculty might carry ideas from their graduate schools to the universities that hired them.The researchers then ran thousands of simulations on that network, allowing ideas that began at one school to percolate down to others. The team adjusted for the quality of ideas by making some more likely to shift between nodes than others.The findings, published in October in the journal EPJ Data Science, show that it matters where an idea gets started. When mid-level ideas began at less prestigious schools, they tended to stall, not reaching the full network. The same wasn’t true for so-so thinking from major universities.  “If you start a medium- or low-quality idea at a prestigious university, it goes much farther in the network and can infect more nodes than an idea starting at a less prestigious university,” Morgan said. That pattern held up even when the researchers introduced a bit of randomness to the mix—allowing ideas to pop from one end of the network to another by chance. That simulated how university departments might learn about an idea through factors other than hiring, such as journals, conferences or word of mouth. Diverse departmentsThe results seem to paint a dim picture of academia, said study coauthor Samuel Way, a postdoctoral research associate in computer science. He explained that recent sociological research demonstrates that workplaces benefit by having a lot of diversity—whether in gender, race or in how employees are trained. “If you have five people who all have the exact same training and look at the world through the same lens, and you give them a problem that stumps one of them, it might stump all of them,” Way said.He added that it may be possible for the academic world to blunt the impact of the sorts of biases the team revealed, including by adopting practices like double-blind peer review—in which the reviewers of a study can’t see the names or affiliations of the authors. “In a setting like science where it’s incredibly difficult to come up with an objective measure of the quality of an idea, double-blind peer review may be the best you can do,” Way said.The study did, however, contain a bit of good news: The bias toward big-name universities mattered a lot less for high-quality ideas. In other words, great thinking can still catch fire in academia, no matter where it comes from.“I think it’s heartwarming in a way,” Morgan said. “We see that if you have a high-quality idea, and you’re from the bottom of the hierarchy, you have as good a chance of sending that idea across the network, as if it came from the top.”Other coauthors on the study included graduate student Dimitrios Economou and Associate Professor Aaron Clauset, both in computer science.last_img read more

Researchers develop dustbuster for the moon

first_img“It’s really annoying,” said Xu Wang, a research associate in the Laboratory for Atmospheric and Space Physics (LASP) at CU Boulder. “Lunar dust sticks to all kinds of surfaces—spacesuits, solar panels, helmets—and it can damage equipment.”So he and his colleagues developed a possible fix—one that makes use of an electron beam, a device that shoots out a concentrated (and safe) stream of negatively-charged, low-energy particles. In the new study, the team aimed such a tool at a range of dirty surfaces inside of a vacuum chamber. And, they discovered, the dust just flew away.“It literally jumps off,” said lead author Benjamin Farr, who completed the work as an undergraduate student in physics at CU Boulder. The researchers still have a long way to go before real-life astronauts will be able to use the technology to do their daily tidying up. But, Farr said, the team’s early findings suggest that electron-beam dustbusters could be a fixture of moon bases in the not-too-distant future. Spent gunpowderThe news may be music to the ears of many Apollo-era astronauts. Several of these space pioneers complained about moon dust, which often resists attempts at cleaning even after vigorous brushing. Harrison “Jack” Schmitt, who visited the moon as a member of Apollo 17 in 1972, developed an allergic reaction to the material and has said that it smelled like “spent gunpowder.”The problem with lunar dust, Wang explained, is that it isn’t anything like the stuff that builds up on bookshelves on Earth. Moon dust is constantly bathed in radiation from the sun, a bombardment that gives the material an electric charge. That charge, in turn, makes the dust extra sticky, almost like a sock that’s just come out of the drier. It also has a distinct structure.

(Credit: NASA)A team led by the University of Colorado Boulder is pioneering a new solution to the problem of spring cleaning on the moon: Why not zap away the grime using a beam of electrons?The research, published recently in the journal Acta Astronautica, marks the latest to explore a persistent, and perhaps surprising, hiccup in humanity’s dreams of colonizing the moon: dust. Astronauts walking or driving over the lunar surface kick up huge quantities of this fine material, also called regolith.  “Lunar dust is very jagged and abrasive, like broken shards of glass,” Wang said. The question facing his group was then: How do you unstick this naturally clingy substance?Electron beams offered a promising solution. According to a theory developed from recent scientific studies of how dust naturally lofts on the lunar surface, such a device could turn the electric charges on particles of dust into a weapon against them. If you hit a layer dust with a stream of electrons, Wang said, that dusty surface will collect additional negative charges. Pack enough charges into the spaces in between the particles, and they may begin to push each other away—much like magnets do when the wrong ends are forced together. “The charges become so large that they repel each other, and then dust ejects off of the surface,” Wang said.Electron showersTo test the idea, he and his colleagues loaded a vacuum chamber with various materials coated in a NASA-manufactured “lunar simulant” designed to resemble moon dust.And sure enough, after aiming an electron beam at those particles, the dust poured off, usually in just a few minutes. The trick worked on a wide range of surfaces, too, including spacesuit fabric and glass. This new technology aims at cleaning the finest dust particles, which are difficult to remove using brushes, Wang said. The method was able to clean dusty surfaces by an average of about 75-85%. “It worked pretty well, but not well enough that we’re done,” Farr said.The researchers are currently experimenting with new ways to increase the cleaning power of their electron beam.But study coauthor Mihály Horányi, a professor in LASP and the Department of Physics at CU Boulder, said that the technology has real potential. NASA has experimented with other strategies for shedding lunar dust, such as by embedding networks of electrodes into spacesuits. An electron beam, however, might be a lot cheaper and easier to roll out. Horányi imagines that one day, lunar astronauts could simply leave their spacesuits hanging up in a special room, or even outside their habitats, and clean them after spending a long day kicking up dust outside. The electrons would do the rest.“You could just walk into an electron beam shower to remove fine dust,” he said.Other coauthors on the new research include John Goree of the University of Iowa and Inseob Hahn and Ulf Israelsson of the Jet Propulsion Laboratory.
