The fight against antibiotic-resistant microbes could suffer a major blow if widely circulated rumours are confirmed that pharmaceutical giant AstraZeneca is due to disband its in-house antibiotic development. The company called the rumours “highly speculative”, while not explicitly denying them.
On 23 October, drug-industry consultant David Shlaes wrote on his blog that AstraZeneca, a multinational behemoth headquartered in London, “has told its antibiotics researchers that they should make efforts to find other jobs in the near future”, and that in his opinion this heralds the end of in-house antibiotic development at the company. “As far as antibiotic discovery and development goes, this has to be the most disappointing news of the entire antibiotic era,” wrote Shlaes.
AstraZeneca would not directly address these claims when approached by Nature for comment. In its statement it said, in full:
The blog is highly speculative. We continue to be active in anti-infectives and have a strong pipeline of drugs in development. However, we have previously said on a number of occasions that as we focus on our core therapy areas (Oncology, CVMD [cardiovascular and metabolic diseases] and Respiratory, Inflammation and Autoimmune) we will continue to remain opportunity driven in infection and neuroscience, in particular exploring partnering opportunities to maximise the value of our pipeline and portfolio.
Research into antibiotics is notorious for its high cost and high failure rate. AstraZeneca has previously said that its main research focus would be on areas other than antibiotic development.
Public-health experts have been warning about a trend among large pharmaceutical companies to move away from antibiotics research — just as the World Health Organization and others have pointed to the rising threat of deadly multi-drug-resistant strains of bacteria such as Mycobacterium tuberculosis or Staphylococcus aureus (see ‘Antibiotic resistance: The last resort‘).
The discovery of Homo floresiensis: Tales of the hobbit

In 2004, researchers announced the discovery of Homo floresiensis, a small relative of modern humans that lived as recently as 18,000 years ago. The ‘hobbit’ is now considered the most important hominin fossil in a generation. Here, the scientists behind the find tell its story.

More than half of all peer-reviewed research articles published from 2007 to 2012 are now free to download somewhere on the Internet, according to a report produced for the European Commission, published today. That is a step up from the situation last year, when only one year – 2011 – reached the 50% free mark. But the report also underlines how availability dips in the most recent year, because many papers are only made free after a delay.
“A substantial part of the material openly available is relatively old, or as some would say, outdated,” writes Science-Metrix, a consultancy in Montreal, Canada, who conducted the study, one of a series of reports on open access policies and open data.
The study (which has not been formally peer-reviewed) forms part of the European Commission’s efforts to track the evolution of open access. Science-Metrix uses automated software to search online for hundreds of thousands of papers from the Scopus database.
The company finds that the proportion of new papers published directly in open-access journals reached almost 13% in 2012. The bulk of the Internet’s free papers are available through other means – made open by publishers after a delay, or by authors archiving their manuscripts online. But their proportion of the total seems to have stuck at around 40% for the past few years. That apparent lack of impetus is partly because of a ‘backfilling’ effect, whereby the past is made to look more open as authors upload versions of older paywalled papers into online repositories, the report says. During this last year, for instance, close to 14,000 papers originally published in 1996 were made available for free.
“The fundamental problem highlighted by the Science-Metrix findings is timing,” writes Stevan Harnad, an open-access advocate and cognitive scientist at the University of Quebec in Montreal, Canada. “Over 50% of all articles published between 2007 and 2012 are freely available today. But the trouble is that their percentage in the most critical years, namely, the 1-2 years following publication, is far lower than that. This is partly because of publisher open access embargoes, partly because of author fears and sluggishness, but mostly because not enough strong, effective open access mandates have as yet been adopted by institutions and funders.”
The report’s conclusions are only estimates, as the automated software does not pick up every free paper, and this incompleteness must be adjusted for in the figures (typically adding around 5-6% to the total, a margin calculated by testing the software on a smaller, hand-checked sample of papers). And many of the articles, although free to read, do not meet formal definitions of open access – for example, they do not include details on whether readers can freely reuse the material. Éric Archambault, the founder and president of Science-Metrix, says it is still hard to track different kinds of open manuscripts, and when they became free to read.
The proportion of free papers also differs by country and by subject. Biomedical research (71% estimated free between 2011 and 2013) is far more open than chemistry (39%), for example. The study suggests that from 2008-2013, the world’s average was 54%, with Brazil (76%) and the Netherlands (74%) particularly high. The United Kingdom, where the nation’s main public funder, Research Councils UK, has set a 45% target for 2013-14, has already reached 64% in previous years, the report suggests.
The study comes during Open Access week, which is seeing events around the world promoting the ideas of open access to research. Yesterday saw the launch of the ‘Open Access Button’ in London – a website and app that allows users to find free research. If no free copy is available, the app promises to email authors asking them to upload a free version of their paper – with an explanation direct from the user who needs the manuscript. “We are trying to make open access personal – setting up a conversation between the author and the person who wants access,” says Joe McArthur, who co-founded the project and works at the Right to Research Coalition, an advocacy group in London.

The 18 great earthquakes that have struck Earth in the past decade hold ominous lessons for western North America, a top seismologist has warned. Many of these large quakes — including the 2004 Sumatra quake that spawned the Indian Ocean tsunami, and the 2011 Tohoku disaster in Japan — were surprisingly different from one another despite their similar geologic settings.
That variety implies that almost any scenario is possible in another part of the Pacific Rim where quake risk is thought to be high — along the Cascadia subduction zone offshore of Washington, Oregon, and other parts of the western United States and Canada.
“We do not fully understand the limits of what can happen,” says Thorne Lay, a seismologist at the University of California, Santa Cruz. “We have to be broadly prepared to respond.”
Lay spoke on 21 October at the Geological Society of America meeting in Vancouver, Canada, a city on the front lines of Cascadia earthquake risk.
The last great quake in the region happened in 1700. Conventional wisdom holds that the next one, perhaps as large as magnitude 9, could strike at any time in the next several hundred years. Geologically speaking, Cascadia is a classic subduction zone, where one plate of Earth’s crust plunges beneath another, building up stress and occasionally relieving it in large earthquakes.
The recent spate of great subduction-zone quakes, of magnitude 8 or larger, began with the 2004 Sumatra earthquake. On average, each year since then has brought 1.8 great quakes, more than twice the rate of the previous century.
In large part, they happened where and when seismologists expected them. “The quakes are basically filling in a deficiency of activity,” Lay says. But their details have been surprising.
The 2004 Sumatra quake, for instance, ruptured unexpected portions of a subduction zone off Indonesia, where the fault zone bends as opposed to running straight. That implies that areas in Cascadia with unusual geometry might also be at risk, Lay says.
In 2007, in Peru, a major earthquake began to happen, then essentially stopped for 60 seconds before picking up again and eventually generating a large tsunami. That start-stop-start pattern raises challenges for Cascadia because seismologists are trying to develop an accurate earthquake early warning system there.
And in April 2014, a Chilean quake ruptured a far shorter portion of a subduction zone than scientists had expected. That suggests that researchers can’t be complacent about thinking they know which parts of Cascadia might break, Lay says. (The worst-case scenario for Cascadia involves a rupture of approximately 1,000 kilometres.)
That’s not to say scientists aren’t preparing. The recently launched M9 project, coordinated out of the University of Washington in Seattle, aims to help officials cope with the risk of a great Cascadia quake. At the Vancouver meeting, Arthur Frankel of the US Geological Survey in Seattle showed early results of calculations of where the ground might shake the most. Enclosed basins, like Seattle, amplify the shaking, he reported.

Researchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.
