<em>Kepler</em> data reveal the exoplanets most likely to have liquid water

4 August 2016
Daily Mail: Among the 4000 new planets discovered by NASA’s Kepler space observatory, 216 are located close enough to their star to contain liquid water on their surface, and of those, 20 appear to be rocky like Earth, according to a new study published in the Astrophysical Journal. Stephen Kane of San Francisco State University and his colleagues say their study represents a “complete catalog of all of the Kepler discoveries that are in the habitable zone of their host stars.” Next the group plans to focus on the short list of Earth-like planets to see if any are actually habitable.

North Korea plans advanced space program, including Moon launch

4 August 2016
Guardian: In an interview with the Associated Press, Hyon Kwang-il, director of the scientific research department of North Korea’s National Aerospace Development Administration, announced that the country is embarking on an ambitious five-year space program. The goal is to launch more Earth observation satellites, one of them a geostationary communications satellite. North Korea currently has two satellites in orbit. Within 10 years, Hyon says, the country plans to launch an unmanned Moon mission. Although concerns over the potential military applications of rocket launches have been raised, Hyon maintains that the satellites will be used solely for communications and to gather data on crops and other vegetation.

US grants first commercial license for a lunar mission

3 August 2016

Ars Technica: Historically, Earth's orbit has been the limit for commercial activity, with an international treaty holding signatory nations responsible for the supervision of all commercial access and use of outer space. Now the US has granted Moon Express, one of the companies competing for Google's Lunar XPrize, approval to send a probe to the Moon, which the company intends to do in 2017. The company applied for the license in April 2015. The approval process, which has not been formalized, included reviews by the Federal Aviation Administration, the Department of State, NASA, and the White House, with input from the Department of Defense, the Federal Communications Commission, and the National Oceanic and Atmospheric Administration. A more formal system will likely need to be developed as other companies, such as SpaceX, are likely to pursue similar licensing.

Permissions rights complicate the use of large data sets

3 August 2016

Nature: Just because a data set has been made public doesn't mean that other researchers can use the data however they please. For example, University of Pennsylvania data scientist Daniel Himmelstein has set up Hetionet, an online resource based on 28 public data sets that shows the known connections between drugs, diseases, and genes . When creating it, Himmelstein contacted the researchers who published the data sets to get permission to reproduce the work publicly. Several never responded or replied in ways that didn't clarify whether he had been granted permission to publish. Generally a fact or a piece of data is not copyrightable, but the European Union and some countries treat data sets in a way that limits republication. In the US, where data sets are not directly protected, it is arguable that the compilation and organization of a data set's facts could have similar protections.

Io's atmosphere turns into frost in Jupiter's shadow

3 August 2016

Science: During its orbit of Jupiter every 42 hours, the moon Io takes about two hours to pass through the gas giant's shadow. In that time the temperature on the surface cools from –146 °C to –168 °C. Astronomers have used a ground-based IR telescope and observed that during that period roughly 80% of Io's primarily sulfur dioxide atmosphere turns to frost and settles onto the moon's surface. When Io moves out of Jupiter's shadow, the frost turns back into gas.

AMS report: 2015 set several climate records

3 August 2016

The Guardian: On 2 August the American Meteorological Society released its 26th annual State of the Climate report, which is compiled by the National Oceanic and Atmospheric Administration with input from hundreds of scientists around the world. The report indicates that 2015 saw record highs for atmospheric and oceanic temperatures, sea levels, and atmospheric carbon dioxide. The annual surface temperature increased 0.1 °C over 2014, and thus the global temperature is now 1 °C warmer than during preindustrial times. The eastern Pacific Ocean, which experienced further warming from El Niño, was 2 °C warmer than the long-term average, and the Arctic was 8 °C over its average. Oceanic warming contributed to a sea level that is about 70 mm higher than the average in 1993, when satellite measurements of sea levels began. The report also pointed to record lows for Arctic maximum sea-ice coverage and a net loss of alpine glacier ice for the 36th consecutive year.

UK research head wants to use Brexit to improve research funding system

2 August 2016

BBC: Earlier this year, the British government established UK Research and Innovation (UKRI) to oversee the nine organizations that manage the country's £6 billion ($8 billion) of annual research funding. Former permanent secretary of the Treasury John Kingman was appointed its head. In the wake of the Brexit vote and the impending loss of about £850 million yearly in research funding from the European Union, Kingman says that he wants to strengthen the connections between the UK research funding organizations. At the same time, he says he does not want to undermine the strengths of those organizations, including their close connections with researchers. He says that the UKRI will provide a broad perspective that helps to unite the organizations in their funding goals.

New studies speed analysis of extreme weather events

2 August 2016
New York Times: Over the past decade, more complex computer models and ever-increasing amounts of weather data have been allowing climate scientists to not only better understand extreme weather events but also determine whether they were caused by climate change. An international effort called World Weather Attribution (WWA) has been working to accelerate such analyses and communicate the results. WWA scientists have found they achieve the best results by running climate models many times, varying the parameters, and averaging the results, which is a time-consuming process. To speed up their analysis of current weather events, the researchers rely on models that have already been run. Most recently, WWA scientists were able to determine within two weeks that the severe flooding in France last month was likely caused by climate change. The evidence was inconclusive regarding similar flooding in Germany.

Variable star is actually an unusual binary system

2 August 2016

Ars Technica: AR Scorpii was originally classified as a variable M-class star whose brightness varies over a period of 3.5 hours. However, an archive of images revealed additional variability beyond the originally observed periodicity. The star's maximum brightness varied by up to a factor of four. A more careful observation of the star revealed that the star's light alternated between being red-shifted and being blue-shifted over the same 3.5-hour period. The only explanation is the presence of a closely orbiting body roughly one-third as massive as the Sun—a white dwarf. The binary system also produces significantly more IR and radio emissions than would normally be expected. The extra light appears to be the result of photon emissions from extremely fast-moving electrons bombarding the M-class star. Researchers believe that the slowing of the white dwarf's current high rate of rotation may be involved in whipping up the electrons.

Gender gap persists in the physical sciences

2 August 2016
Nature: Even though women make up 49–58% of all undergraduates and graduates in the social and life sciences in the US, just 20% of physics students are female. To address the gaping gender gap in the field of physics education, the journal Physical Review Physics Education Research has published a special issue consisting of an editorial and 17 papers that include discussions of hurdles keeping women from entering the field, deterrents from finishing their degrees, the dearth of role models, persistent stereotypes, lack of self-confidence, and sexual harassment. Addressing those problems might entail the introduction of explicit codes of conduct, employment of more women faculty, and improvements in mentoring and teaching. Studies have shown that diversity in educational institutions benefits everyone, because productivity goes up and work–life balance improves.

Invisibility cloaks may not be useful at macroscopic scales

1 August 2016

New Scientist: Passive invisibility cloaks, which redirect light around objects without needing additional energy, may not be possible for macroscopic objects. Andrea Alù and Francesco Monticone of the University of Texas at Austin have shown that the size of the cloak and the range of wavelengths that it could redirect are inversely proportional. A cloak large enough to cover a person would redirect only a specific color of light, whose wavelength would be narrower than even the best lasers can produce. The researchers say that active cloaks, which use input energy to redirect or reemit light, may still be possible.

Two UK climate-denying advocacy group members lose climate change bet

1 August 2016

Guardian: In 2008, Ian Plimer and Alan Rudge, two members of a UK advocacy group called Global Warming Policy Foundation, which challenges the concept of climate change, accepted a bet proposed at a conference by climate scientist James Annan and climate economist Chris Hope. Annan and Hope offered to bet £1000 on 2015 being warmer than 2008; Plimer and Rudge took the bet—and lost. Some scientists are hoping to make betting on climate change a more common tactic when dealing with climate skeptics. The idea is to challenge climate deniers to support their beliefs with actions and not just words.

Climate change policy may be key issue in upcoming US presidential election

1 August 2016
New York Times: Climate change is being discussed by US presidential candidates, and it may prove to be a key issue in choosing the new commander in chief. Like most Democrats, candidate Hillary Clinton is a strong proponent of climate change action, and she has spoken many times about her plan to address global warming. Donald Trump, however, has been extremely vocal in his opposition to the idea of climate change; he claims it’s just a hoax. If elected, he has said he plans to rescind President Obama’s climate change regulations and withdraw the US from its commitment to abide by the recent Paris climate agreement. Trump’s views may alienate some Republicans who oppose Obama’s policies but don’t necessarily deny climate change outright.

Japan space agency considering replacement satellite after <em>Hitomi</em> failure

1 August 2016
Nature: Following the catastrophic loss of the Hitomi satellite shortly after launch earlier this year, the Japan Aerospace Exploration Agency is already considering a replacement mission. Hitomi 2, which would be designed to carry out Hitomi’s original objectives of studying the structure and evolution of the universe, would require the rebuilding of one of Hitomi’s key instruments, an x-ray spectrometer provided by NASA. Representatives from the two agencies are meeting 5 August to discuss the project.

Clinton says "I believe in science" in acceptance speech

29 July 2016

Geekwire: In Hillary Clinton's nomination acceptance speech at the Democratic National Convention, she stated that when it comes to climate change she accepts the scientific consensus. That puts her in direct contrast to Donald Trump, the Republican candidate, who has in the past called global warming a hoax and a money-making industry. Science is rarely mentioned in political campaigns—Trump didn't use the word at all in his own acceptance speech—so Clinton's "I believe in science" line resulted in a lot of plaudits from scientific commentators on social media. Clinton also shared her belief that shifting to clean energy will help bolster the US economy and drive technology and innovation.
