Seven days: 15 21 november 2013heat tracking This year is on track to become the seventh-warmest since global climate records began in 1850, according to a preliminary assessment released on 13  November by the World meteorological organization. See go. nature. com/apxlsn for more. Asian unicorn A rare antelope-like animal called the saola has been caught on film for the first time in 15 years. The conservation group WWF snapped the photos using a camera trap in Vietnam, and announced the finding on 12  November. The saola (Pseudoryx nghetinhensis), sometimes nicknamed the Asian unicorn is endangered critically, and probably only a few hundred remain.

Philippe MASCLET/Masterfilms/Airbusgiant ash cloud tests sensor for aircraft Sensors to detect volcanic ash have moved closer to widespread use on commercial airlines following flight tests involving the world s biggest artificial ash cloud (pictured. The Airborne Volcanic Object Imaging Detector (AVOID), developed by Nicarnica Aviation in Kjeller, Norway, uses infrared cameras to detect low levels of ash in the atmosphere. The test cloud was created on 30  October by spraying particles collected from Iceland s Eyjafjallajã kull volcano into the air off the west coast of France (see Nature 502,422-423; 2013). ) Easyjet, the UK airline carrier that helped to fund the experiment, announced on 13  November that it would mount the AVOID sensor on a number of its commercial jets by the end of next year. Volcanic ash can melt in the high temperatures of jet engines, clogging the equipment. Fukushima fuel Workers in Japan have taken the first steps towards fully decommissioning the stricken Fukushima Daiichi nuclear power plant. On 18  November, the Tokyo Power and Electric Corporation began the delicate task of removing fuel rods from a damaged reactor building. Although the unit was offline during the disastrous March 2011 earthquake falling debris from the accident had made it difficult to transfer spent fuel kept in the building to permanent storage. MAVEN launch NASA s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is on its way to study the upper atmosphere of the red planet. The mission launched on 18  November from Cape canaveral, Florida, and will explore how atoms escape from the Martian atmosphere. MAVEN should reach its destination next September; once there, it will carry out a one-year nominal mission (see Nature 503,178; 2013). ) Japan emissions Japan has scaled back its commitment to reduce greenhouse-gas emissions, according to news reports on 15  November. The country had pledged previously to lower emissions by 25%by 2020 compared with 1990 levels. But the new commitment a 3. 8%decrease over 2005 levels would set Japan s emissions targets at 3. 1%above 1990 baselines. The news comes as United nations climate talks are under way in Warsaw. See Nature 503,174-175 (2013) and page 311 for more. Brain implant Patients with epilepsy who fail to respond to medications could benefit from a newly approved brain implant. The RNS Stimulator made by Neuropace of Mountain view, California, received a green light from the US Food and Drug Administration on 14  November. The device is implanted in the skull and detects abnormal electrical activity in the brain, delivering corrective electrical stimulation preemptively to the brain areas in which epileptic seizures are thought to originate. Malaria strategy Researchers should aim to develop malaria vaccines by 2030 that can reduce the disease by 75, %the World health organization said on 14  November in its updated Malaria Vaccine Technology Roadmap. The original 2006 roadmap had called for a malaria vaccine with an efficacy of 50%against severe disease and death a target that seems unlikely to be met (see Nature 502, 271-272; 2013). ) To accelerate progress, the revised plan recommends rapid assessment of new candidate vaccines using controlled studies in humans. Heart health Long-awaited clinical guidelines released on 12  November could change how physicians tackle cholesterol. The guidelines, issued by the American Heart Association and the American College of Cardiology, advocate treating patients on the basis of their risk of cardiovascular disease, rather than trying to reduce bad cholesterol (made up of low-density lipoprotein) to specific target levels, as had been recommended previously.

Biofuel rules The US Environmental protection agency proposed reducing requirements for the use of biofuels on 15  November citing technical difficulties in meeting the current standards. The proposal would require that biofuels make up 9. 2%of the US transportation fuel supply in 2014, down from 9. 74%in 2013. The requirement for advanced biofuels, which must reduce greenhouse-gas emissions by at least half, would drop from 1. 62%to 1. 33%.%The rule is projected to reduce maize (corn) ethanol consumption by 3  billion litres next year, compared with 2013. Franklin Orrus energy nominees Chemical engineer Franklin Orr (pictured) has been tapped by US President Barack Obama to serve as the undersecretary for science at the Department of energy. Orr, a researcher at Stanford university in California, would replace Steven Koonin as chief scientific adviser to US energy secretary Ernest Moniz, and would oversee the department s research programmes. Meanwhile, Marc Kastner, a physicist at the Massachusetts institute of technology in Cambridge, was nominated to head the department s Office of Science. Both picks must be confirmed by the Senate. See go. nature. com/geeup9 for more. Science educator Microbiologist Ann Reid will be the new head of the US National Center for Science Education (NCSE) in Oakland, California. The nonprofit organization campaigns against the teaching of creationism and climate-change denial in schools. Reid, formerly director of the American Academy of Microbiology in Washington  DC, will replace retiring NCSE director Eugenie Scott, who has led the organization for 27 years (see Nature 497,287-288; 2013). ) Broad investment American philanthropists Eli and Edythe Broad announced on 14 november a US$100-million investment to continue funding biomedical research at the Broad Institute in Cambridge, Massachusetts. The centre, which was founded in 2004, supports collaborations between scientists at the Massachusetts institute of technology and Harvard university. The Broads launched the institute with an initial $100-million gift, and have contributed already a further $500  million (see Nature 455,149; 2008). ) Breakthrough drug The US Food and Drug Administration (FDA) approved on 13  November a breakthrough therapy to treat a rare blood cancer called mantle-cell lymphoma. Ibrutinib, developed by Pharmacyclics of Sunnyvale, California, is only the second drug to be approved under the FDA s Breakthrough Therapy Designation programme a pipeline launched last year to fast-track regulatory approval of particularly promising treatments. See go. nature. com/w5xfjo for more. Source: C.  Southan et  al. PLOS ONE 8, e77142 (2013) The number of potential drug leads disclosed in patents each year has plummeted over the past seven years. But potentially bioactive molecules described in research journals are still rising, according to a data-mining study of molecular structures in more than 140,000 journal articles and patents (C.  Southan et  al. PLOS ONE 8, e77142; 2013). ) The researchers suggest that job cuts and mergers among pharmaceutical companies may be behind the fall in global output. 22 november The European space agency is scheduled to launch Swarm, a constellation of satellites that will study Earth s magnetic field for four years. go. nature. com/rxaaur24-27 november Science for global sustainable development is the theme of the sixth World Science Forum, to be held in Rio de janeiro, Brazil. Highlights include biodiversity, water security and bioenergy. go. nature. com/cxmbqf
