Astronomy & Space news

	Pluto stuns in spectacular new backlit panorama The latest images from NASA's New Horizons spacecraft have scientists stunned – not only for their breathtaking views of Pluto's majestic icy mountains, streams of frozen nitrogen and haunting low-lying hazes, but also for their strangely familiar, arctic look.
	Researchers propose new way to chart the cosmos in 3D If only calculating the distance between Earth and far-off galaxies was as easy as pulling out the old measuring tape. Now UBC researchers are proposing a new way to calculate distances in the cosmos using mysterious bursts of energy.
	Big Iron gets technology boost ESA deploys 'big iron' to communicate with its deep-space missions: three 35 m-diameter dishes employing some of the world's most advanced tracking technology. And it's about to get a boost.
	Stellar atmosphere can be used to predict the composition of rocky exoplanets In two recently published articles, researchers from Instituto de Astrofísica e Ciências do Espaço (IA) show that the ratio of some heavy elements in a star, like Magnesium (Mg), Silicon (Si) and Iron (Fe), have a crucial influence in the composition of rocky exoplanets.
	Adventures with Starblinker Observational astronomy is a study in patience. Since the introduction of the telescope over four centuries ago, steely-eyed observers have watched the skies for star-like or fuzzy points of light that appear to move. Astronomers of yore discovered asteroids, comets and even the occasional planet this way. Today, swiftly moving satellites have joined the fray. Still other 'new stars' turn out to be variables or novae.
	Space balloons and charged particles above the Arctic Circle I research space weather. That's how physicists describe how storms on the sun end up affecting us here on Earth. Most days I sit at a computer coding, attending telephone conference meetings with collaborators across the country and meeting with fellow space physicists. But sprinkled throughout the year I get to do exciting fieldwork in remote locations. We launch high-tech space balloons in an effort to help untangle what happens when charged particles from solar storms hit the Earth's magnetic field, called its magnetosphere.
	Secrets of Soviet space race come to London The space technology that saw the Soviet Union propel the first dog, man and woman into orbit has gone on show in London—most of it being exhibited outside Russia for the first time.
	Image: Pluto's majestic mountains, frozen plains and foggy hazes Just 15 minutes after its closest approach to Pluto on July 14, 2015, NASA's New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto's horizon.
	This is a scale model of the solar system like you've never seen before We've all seen illustrations of the solar system. They're in our school textbooks, on posters, on websites, on t-shirts… in some cases they're used to represent the word "science" itself (and for good reason.) But, for the most part, they're all wrong. At least where scale is concerned.

Technology news

	A 3D printing method embeds interactivity into printed objects Talk about rapid prototyping—A team from the Human Media Lab of Queen's University in Canada have been exploring a way of being able to integrate touch and pressure sensors directly into 3D-printed objects.
	New method optimizes outcomes for subjects in comparison tests Clinical trials of new drugs or devices face a problem that most empirical inquiries don't: They must not only provide clear data about toxicity and efficacy but also try to maximize the quality of treatment for all of the patients enrolled.
	Hacking sends shivers through brave new world of digital cars The connected car may be catching everyone's imagination at this year's IAA auto show. But the new technology also brings with it new dangers, such as hacking.

	Midwest wind energy to get projected lift from climate change, study says Mother Nature will be delivering a future gift of 2 percent more wind energy in the Midwest if regional climate models are correct, according to research from Wake Forest University.
	The internet hasn't killed privacy – but it has changed it forever When people say "privacy is dead", it's usually for one of two reasons. Either they truly believe that privacy is irrelevant or unachievable in today's hyper-connected world or, more often, that not enough is being done to protect privacy when huge amounts of personal information are being posted online. Although I agree more could be done to protect privacy online, I believe that privacy is not dead, it's just changing forms.
	Researchers developed highly accurate method for measuring luminous efficacy of LEDs The method helps discovering the most efficient lamps, which may save billions in lighting costs in the future.
	All words from all languages in one dictionary The universal online dictionary Kamusi has just added 1.2 million terms from several databases in its quest to translate all the meanings of every word in all the world's languages. Three African languages and 200,000 words of Vietnamese will soon follow.
	Mobile app automatically sends a caller's location and medical data to dispatch centers The nation's 911 dispatch centers aren't really equipped for the mobile world.
Can smartphones use less energy to browse the web? Web browsing is one of the core applications on smartphones. After all, who hasn't checked Facebook or watched the latest news—or amusing cat videos—on their mobile phone? However, mobile browsers on smartphones are primarily optimized for performance, not energy efficiency, so web browsing—especially the loading of web pages—tends to drain batteries and frustrate users.
The precision of solar photovoltaic power measurements doubled An analysis carried out by JRC scientists shows that the uncertainty in measurement of power generation from a photovoltaic (PV) cell can be more than halved, thus bringing an economic benefit to both manufacturers and investors. With the annual world PV production exceeding 40 GW in 2014 and a market value of over €25bn, this is good news for customers, utilities, the production industry and future R&D efforts in the field of renewable energy.
	US accuses Volkswagen of cheating on pollution controls US regulators charged Volkswagen on Friday with manufacturing vehicles designed to evade government pollution controls and said the German auto giant should fix nearly 500,000 cars with the defect.
	Xerox launches printed memory products to combat counterfeiting To help businesses and government better secure products as they are distributed, Xerox today introduced two printed electronic labels (also known as "printed memory") that can collect and store information about the authenticity and condition of products.

Biology news

	Flowing electrons help ocean microbes gulp methane Good communication is crucial to any relationship, especially when partners are separated by distance. This also holds true for microbes in the deep sea that need to work together to consume large amounts of methane released from vents on the ocean floor. Recent work at Caltech has shown that these microbial partners can still accomplish this task, even when not in direct contact with one another, by using electrons to share energy over long distances.
	Harvesting clues to GMO dilemmas from China's soybean fields China's struggle - mirrored across the globe—to balance public concern over the safety of genetically modified (GM) crops with a swelling demand for affordable food crops has left a disconnect: In China's case, shrinking fields of domestic soybean - by law non-GM—and massive imports of cheaper soybeans that are the very GM crop consumers profess to shun.
	Photosynthesis gene can help crops grow in adverse conditions A gene that helps plants to remain healthy during times of stress has been identified by researchers at Oxford University. Its presence helps plants to tolerate environmental pressures like drought—and it could help create crops that can better withstand adverse conditions.
	New findings help explain how molecules are speedily transported into and out of the cell's nucleus A cell does everything it can to protect its nucleus, where precious genetic information is stored. That includes controlling the movement of molecules in and out using gateways called nuclear pore complexes (NPCs).
	Scientists identify gene that triggers neural remodeling during C. elegans development A gene that triggers remodeling of neural circuits in C. elegans during development has been identified by Michael Francis, PhD, associate professor of neurobiology. The study, details of which were published in Current Biology, is among the first to actively record rewiring of neural synapses in a live animal model, identifying the OIG-1 gene as a master regulator of this process.

	High-fat diet made Inuits healthier but shorter thanks to gene mutations, study finds For evolutionary biologists, the best experiments are those already going on in nature. The different conditions in which humans have lived for tens of thousands of years have made us adapt and change. Now a new study published in Science shows that such adaptation has led to genetic mutations in Greenlandic Inuits that help them counteract the bad effects of their high-fat diet, based heavily on fish and marine mammals.
Unexpected role for the IKK complex in protecting cells from death The team of Prof. Bertrand in the group of Prof. Vandenabeele, demonstrates that the IKK complex protects cells from death by inactivating RIPK1, thereby revealing an unexpected NF-kB-independent new role of the IKK complex.
	Students surprised by how smart chickens are University of Adelaide research has shown that when students are taught to train chickens their attitude to chickens changes. Learning that chickens are smarter than most people think, and that they can be trained, promotes much more positive attitudes towards the birds.
	Five things dung beetles do with a piece of poo Dung beetle behaviour has fascinated humans for thousands of years – including the ancient Egyptians, who incorrectly believed the beetles reproduced only from males. But Egyptian observations that the beetles' ball rolling is influenced by the sun is accurate and could be the first recorded accounts of animal behaviour.
British bid to genetically modify human embryos Britain's embryology regulator has received an application to genetically modify an embryo, which would be the first such attempt since a Chinese effort earlier this year.
Gray wolf confirmed in northern Lower Peninsula It took a year and a half, but there's now no doubt: The animal spotted on a trail camera in Emmet County in the northwestern Lower Peninsula was indeed a gray wolf - only the second one confirmed in the Lower Peninsula since 1910.
	Satellite technology puts 'mussel' into shellfish monitoring University of Exeter researchers are working with a team of UK scientists to explore the use of satellites and meteorological data to monitor and forecast water quality events that could threaten shellfish farms. The results will benefit the shellfish industry and, ultimately, consumers.
