Astronomy & Space news

	Delta Cephei's hidden companion To measure distances in the universe, astronomers use cepheids, a family of variable stars whose luminosity varies with time. Their role as distance calibrators has brought them attention from researchers for more than a century. While it was thought that nearly everything was known about the prototype of cepheids, named Delta Cephei, a team of researchers at the University of Geneva (UNIGE), the Johns Hopkins University, and the European Space Agency (ESA), have now discovered that this star has a hidden companion. They have published an article about the discovery in The Astrophysical Journal.
	More evidence that the Milky Way has four spiral arms Astronomers have been arguing over just how many spiral arms our galaxy exhibits. Is the Milky Way a four or two-armed spiral galaxy? Astronomers had often assumed the Milky Way was potentially a four-armed spiral galaxy, but comparatively recent observations from NASA's Spitzer telescope implied the galaxy had two spiral arms. In 2013, astronomers mapped star forming regions and argued they had found the two missing arms, bringing the total number of arms back to four.
	Image: Serene Saturn From a distance Saturn seems to exude an aura of serenity and peace.
	Ether compounds could work like DNA on oily worlds In the search for life beyond Earth, scientists have justifiably focused on water because all biology as we know it requires this fluid. A wild card, however, is whether alternative liquids can also suffice as life-enablers. For example, Saturn's frigid moon Titan is awash in inky seas of the hydrocarbon methane.
	Russian launch failure delays landing for space station crew The launch failure of an unmanned Russian cargo spaceship has prompted the nation's space agency to delay both the landing of some of the International Space Station's crew and the launch of their successors, officials said Tuesday.
	NASA selects advanced space technology concepts for more study NASA has selected 15 proposals, including one from NASA's Jet Propulsion Laboratory, Pasadena, California, for study under Phase I of the NASA Innovative Advanced Concepts (NIAC), a program that aims to turn science fiction into science fact through the development of pioneering technologies.
	Despite heavy storms and rough seas, team captures missile flight data "Everything was very successful, but this was the toughest mission we've ever supported." That was the assessment of Steve Yakuma, LLNL's ICBM flight test director, when asked to sum up his team's support of the recently completed GT214 and GT215 missile flight tests off of Saipan in the South Pacific.
	What shape is the universe? The universe. It's the only home we've ever known. Thanks to its intrinsic physical laws, the known constants of nature, and the heavy-metal-spewing fireballs known as supernovae we are little tiny beings held fast to a spinning ball of rock in a distant corner of space and time.
NASA funds SwRI instrument to date moon and Mars rocks NASA has approved $2.6 million to advance development of Southwest Research Institute's (SwRI) Chemistry, Organics, and Dating Experiment (CODEX) instrument. The device will allow unmanned rovers to analyze the decay of radioactive elements to determine the age of rocks on the Moon and Mars.

Technology news

	Controlling swarms of robots with light and a single finger Using a smart tablet and a red beam of light, Georgia Institute of Technology researchers have created a system that allows people to control a fleet of robots with the swipe of a finger. A person taps the tablet to control where the beam of light appears on a floor. The swarm robots then roll toward the illumination, constantly communicating with each other and deciding how to evenly cover the lit area. When the person swipes the tablet to drag the light across the floor, the robots follow. If the operator puts two fingers in different locations on the tablet, the machines will split into teams and repeat the process.
	The $9 computer wants you. CHIP heats up on Kickstarter Headlines about a computer's pricetag beyond consumer imaginations have been rolling in this week. They're calling it the Raspberry Pi killer. The crazy-cheap computer. The every-hacker's dream toy. By now you may have seen the stories about this $9 computer called CHIP. The computer is up on Kickstarter and aims to make some history and enough dollars to get it to market. CHIP is also making news simply based on its quick climb up to its crowdfunding goal, and far beyond. The team hoped to raise $50,000, to help them buy components, they said, "in extremely large quantities." They instead gathered $858,147 at the time of this writing with 25 days still left to go.
	Verizon barges into online video, buying AOL for $4.4B Verizon is buying AOL for about $4.4 billion, advancing the telecom's push in both mobile and advertising fields.
	Shifting winds: An early warning for reduced energy The Rocky Mountains certainly aren't known for their mild winters. But in contrast to the upper Midwest, which seems to exist in a perpetually frozen state from November through March, the plains just east of the Rockies do get an occasional reprieve from the bitter cold: the Chinook winds. When these strong, warm winds blow, they can raise temperatures as much as 50 degrees Fahrenheit and melt away the snow—a welcome respite for residents sick of sweeping slick sidewalks and wearing puffy parkas.
	Researchers create a promising solution for urban toilets They call them frogmen. Their job is to climb into 8-foot-deep pit latrines, empty them with a bucket, then cart away mountains of human waste.
	Women drivers closing the mileage gap While men still drive more miles annually, women are slowly catching up, says a University of Michigan researcher.
	Switzerland's first driverless car hits Zurich roads Swiss telephone firm Swisscom on Tuesday unveiled a driverless car that is being tested on the roads of Zurich, a first in the country.
E-skin and pocket-sized diagnostic machines give patients the power back Wearable E-skin that can measure heart rate and blood pressure, and paper diagnostic machines the size of a credit card that can give instant readings on blood and saliva samples are two new bio-sensing technologies presented at Elsevier's 4th International Conference on Bio-Sensing Technology in Lisbon, Portugal on 12 May 2015.
Verizon Wireless, Sprint settle allegations of bogus charges Verizon Wireless will pay $90 million and Sprint $68 million to settle charges that the mobile giants allowed phony charges on their customers' monthly bills so they could keep a cut of the profit, federal regulators announced Tuesday.
	AOL signs off after 30-year connection Over its 30-year history, the company got America on the Internet, became a corporate power, lost its luster and reinvented itself several times in an effort to stay relevant.
Renewable energy vital for Internet lifestyles: Greenpeace A Greenpeace report released on Tuesday charged utilities with hampering efforts to use renewable energy to power data centers needed for services hosted in the cloud.
	Volvo Trucks first with automatic all-wheel drive—for improved driveability and economy Volvo Trucks' new feature Automatic Traction Control activates the drive on the front axle automatically when in motion, if the truck risks getting stuck. The driver enjoys improved manoeuvrability, and the owner benefits from lower fuel consumption and less wear and tear on the truck.
	DARPA seeks a "100x zoom lens" for seeing distant space objects more clearly Imaging of Earth from satellites in space has vastly improved in recent years. But the opposite challenge—using Earth-based systems to find, track and provide detailed characterization of satellites and other objects in high orbits—has frustrated engineers even as the need for space domain awareness has grown. State-of-the-art imagery of objects in low Earth orbit (LEO), up to 2,000 km (1,200 miles) high, can achieve resolution of 1 pixel for every 10 cm today, providing relatively crisp details. But image resolution for objects in geosynchronous Earth orbit (GEO), a favorite parking place for space assets roughly 36,000 km (22,000 miles) high, drops to just 1 pixel for every 2 meters, meaning many GEO satellites appear as little more than fuzzy blobs when viewed from Earth. Enabling LEO-quality images of objects in GEO would greatly enhance the nation's ability to keep an eye on the military, civilian and commercial satellite! s on which society has come to depend, and to coordinate ground-based efforts to make repairs or correct malfunctions when they occur.
	Researchers develop a novel organic device for obtaining hydrogen from water and sunlight Hydrogen has great potential as a fuel. Researchers at the Photovoltaic and Optoelectronic Devices Group at the Universitat Jaume I have developed an organic device reduces water into hydrogen using only sunlight. Currently, organic materials used in these devices offer greater versatility and efficiency at a lower cost than the available inorganic ones, but they show stability problems when in contact with an aqueous medium. A study published in the Journal of Physical Chemistry achieves an exceptional stability in these devices and represents an important step in obtaining solar fuels from organic materials.
JPMorgan to convert Chase cards to chip technology JPMorgan Chase will replace all of its customers' debit cards with more secure chip-based cards nationwide, the bank said Tuesday, and expects to have chips on 70 percent of its debit cards by the end of 2015.

	Children exposed to multiple languages may be better natural communicators Young children who hear more than one language spoken at home become better communicators, a new study from University of Chicago psychologists finds. Effective communication requires the ability to take others' perspectives. Researchers discovered that children from multilingual environments are better at interpreting a speaker's meaning than children who are exposed only to their native tongue. The most novel finding is that the children do not even have to be bilingual themselves; it is the exposure to more than one language that is the key for building effective social communication skills.

	MRI shows potential to improve breast cancer risk prediction Magnetic resonance imaging (MRI) provides important information about a woman's future risk of developing breast cancer, according to a new study published in Radiology. Researchers said the findings support an expanded role for MRI in more personalized approaches to breast cancer screening and prevention.
	Deciphering the neural code that links food to aging Diet exerts a major impact on health and ageing. The nervous system plays an important role in this process but, thus far, how food signals are interpreted by the nervous system has been a mystery. This is an important question because the perception of food by the nervous system impacts not just ageing, but also other processes associated with health and disease, including metabolism, reproduction, and development.
	Exoskeleton that helps paralyzed walk faces barrier in Japan Yuichi Imahata's 9-year-old daughter is thrilled her dad stands tall above her head. It's an experience that is new to her.
	New malaria test could lead to global eradication of the disease One of the biggest difficulties faced by worldwide programs aimed at eliminating malaria is that the tests they use are not sensitive enough to detect all people who have the disease and need treatment. A study appearing online today in Clinical Chemistry, the journal of AACC, shows that a new test known as capture and ligation probe-PCR (CLIP-PCR) could diagnose the malaria cases that would typically escape detection and lead to new infections.
	Plant extracts offer hope against diabetes and cancer Diabetes is the fastest growing metabolic disease in the world. A new study has shown that traditional Aboriginal and Indian plant extracts could be used to manage the disease and may also have potential use in cancer treatment.

	Significant progress made toward individualized cancer immunotherapy Mainz-based researchers have made significant advances with regard to the development of individualized immunotherapy strategies for treating cancer. They have managed to identify the relevant genetic changes or mutations associated with various types of cancer and have determined their individual blueprints. This makes it possible for the scientists to readily produce customized cancer vaccines of the kind that have already been demonstrated to be effective in animal models. Here they have proven effective in the regression and even elimination of experimental tumors. Headed by cancer researcher Professor Ugur Sahin, participants in the successful project included researchers at the biopharmaceutical research institute TRON – Translational Oncology at the University Medical Center of Johannes Gutenberg University Mainz gGmbH, the biotech company BioNTech AG, the Mainz University Medical Center, and the Californian La Jolla Inst! itute for Allergy and Immunology in the USA. Their results have recently been published in the journal Nature.
	Malaria testing yet to reach its potential In a study published this month in Malaria Journal, researchers from Uppsala University and other institutions present a new model for systematically evaluating new malaria treatment programs in routine conditions across multiple countries.
	How do neurons and blood vessels "talk" to each other? Neurons and blood vessels often traverse the body side by side, a fact observed as early as the 16th century by the Flemish anatomist Andreas Vesalius. Only over the last ten years, however, researchers have discovered that the growth of neuronal and vascular networks is controlled by the same molecules. Prof. Amparo Acker-Palmer, a pioneer in this area, performs groundbreaking research on the communication between neurons and blood vessel cells in the brain. She hopes to use her findings to gain important insights into brain diseases such as dementia and mental illness. The European Research Council will fund her project with an Advanced Investigator Grant of 2.5 million euros over the next five years.
	Baby talk: Babies prefer listening to their own kind A McGill University/UQAM research team has discovered that six-month-old infants appear to be much more interested in listening to other babies than they are in listening to adults. The researchers believe that an attraction to infant speech sounds may help to kick start and support the crucial processes involved in learning how to talk.

Survival from rare bone cancer remains low Among the deadliest cancers is a rare malignancy called mesenchymal chondrosarcoma, which begins in cartilage around bones and typically strikes young adults.
Public health advisories linked with reduction of codeine dispensing to postpartum women Public health advisories from the U.S. Food and Drug Administration (FDA) and Health Canada were associated with significant reductions in the rate of dispensing of codeine to postpartum women, according to a study in the May 12 issue of JAMA.
	Finding should enhance treatments that stop immune system attack Scientists at The University of Manchester have made an important discovery about an immune cell which is already being used in immunotherapy to treat diseases such as type I diabetes.
	Cause of regression in individuals with Down syndrome identified Down syndrome, the most common chromosomal disorder in America, can be complicated by significant deterioration in movement, speech and functioning in some adolescents and young adults. Physicians previously attributed this regression to depression or early-onset Alzheimer's, and it has not responded to treatments. Now, a researcher at the University of Missouri has found that Catatonia, a treatable disorder, may cause regression in patients with Down syndrome. Individuals with regressive Down syndrome who were treated for Catatonia showed improvement, the researcher found.
Rethinking the rebound: Unexpected effects of rejection It's portrayed in movies again and again - a character gets rejected by someone attractive and then falls willingly into the arms of someone perhaps less attractive. According to a new study, it's not so simple: Rejection by an attractive man actually led women to socially distance themselves from an unattractive man, even when he offered acceptance.
	siRNA-toting nanoparticles inhibit breast cancer metastasis Researchers at Case Western Reserve University combined finely crafted nanoparticles with one of nature's potent disrupters to prevent the spread of triple-negative breast cancer in mouse models.

	Smoking and angioplasty: Not a good combination Quitting smoking when you have an angioplasty can help maximize the procedure's benefits, meaning better quality of life and more relief from your chest pain, according to new research in the American Heart Association's journal Circulation: Cardiovascular Interventions.
	Men benefit from vaccinating girls against HPV but remain at risk of some cancers Men benefit indirectly from vaccinating girls against human papillomavirus (HPV), but remain at risk of cancers associated with the virus, finds a study from The Netherlands published in The BMJ this week.
Medical journals should not avoid political issues that have a bearing on health Criticism of Israeli government policy "is not ipso facto antisemitic, and to label it as such is a tactic to stifle debate," argue leading doctors in an editorial in The BMJ this week.
	Dopamine-producing neurons fulfil important function in the brain Nerve cells that produce dopamine for the purpose of transmitting signals to other cells affect numerous crucial brain functions. This becomes evident in diseases such as Parkinson's and schizophrenia, where dopamine transmission in the brain is impaired. In collaboration with researchers from Bonn, RUB scientists at the Mercator Research Group "Structure of Memory" have now identified in what way a specific form of this important cell is generated and which networks it forms in the course of brain development. In the process, the researchers discovered a data highway of sorts: the nerve cells use not only dopamine for signal transmission, but also the much-faster glutamate.
Scientists regenerate bone tissue using only proteins secreted by stem cells Scientists have discovered a way to regrow bone tissue using the protein signals produced by stem cells. This technology could help treat victims who have experienced major trauma to a limb, like soldiers wounded in combat or casualties of a natural disaster. The new method improves on older therapies by providing a sustainable source for fresh tissue and reducing the risk of tumor formation that can arise with stem cell transplants.

	Plant breeder boosts soybean diversity, develops soybean rust-resistant plant It took decades of painstaking work, but research geneticist Ram Singh managed to cross a popular soybean variety ("Dwight" Glycine max) with a related wild perennial plant that grows like a weed in Australia, producing the first fertile soybean plants that are resistant to soybean rust, soybean cyst nematode and other pathogens of soy.
Bacterial forensics: Tracing a suspect from the microbes on their shoes The microbial 'signatures' found on an individual's personal items, such as their shoes and cell phone, could be used to determine their previous location and trace their movements, according to a small pilot study published in the open access journal Microbiome.
	Beaked whales B-stroke for long dives Foraging animals tread a narrow metabolic tightrope, rationing the energy they expend in the pursuit of food to make the most of a catch. And marine mammals that dive on a single breath of air have to be even more frugal to eke out their meagre oxygen stores. Lucía Martín López and colleagues from the University of St Andrews, UK, and the University of La Laguna, Spain, explain that bigger diving mammals should be able to dive and forage for longer than more diminutive species with the same foraging style, as larger divers should be able to carry more oxygen on board: but the data didn't hold up. '25,000 kg sperm whales and 1000 kg beaked whales perform dives of comparable duration (30–50 min) and depth (600–1200 m),' says Martín López. Intrigued by the beaked whales' powers of endurance, Martín López and her colleagues, Mark Johnson, Patrick Miller and Natacha Aguilar de Soto, realised that they needed to know ! more about the diving styles of beaked whales – ranging in size from Blainville's beaked whales to Cuvier's beaked whales and northern bottlenose whales – to find out more about the impressive duration of their dives.
	All invasive parakeets come from a small region in South America The parakeets that have invaded Europe and North America over the last forty to fifty years, creating massive nests in many urban areas, seem to have originated from the same small geographical area in South America. In addition, the invasive populations are genetically identical and are recognised by a relatively rare dominant haplotype in the source population. This has been the conclusion of an international study in which Spanish scientists have participated.
	Researchers discover how nature enables cells to act intelligently Researchers at the Institute for Basic Science (IBS) have discovered a Lévy walk pattern of movement when living cells eat. When the food is transported within the cell by so-called endosomal active transport, it is the same mathematical pattern of movement that many animals follow when foraging for food.
New light on bacterial microcompartments Bacteria contain "microcompartments," which are poorly understood organelles that play critical roles in metabolism. Understanding how they work may ultimately enable engineering them for useful applications. In salmonella, which possess two microcompartment types, coexpression is prevented by gene regulation. Concurrent expression rendered them nonfunctional, and resulted in release of toxic metabolic intermediates into the cell cytoplasm, damaging the cell. But by engineering a regulatory override, Thomas Bobik, PhD, and collaborators shed new light on how microcompartments work. The research is published in the Journal of Bacteriology, a publication of the American Society for Microbiology.
	Researchers confirm cell wall of anammox bacteria contains the structural molecule peptidoglycan Contrary to what you will read in textbooks, the cell wall of anammox bacteria contains the structural molecule peptidoglycan after all. This is the conclusion of a group of microbiologists from Radboud University, Umeå University (Sweden) and Indiana University (the US) in an article in Nature Communications, published on May 12.
	Best conservation practices consider both genetics and biology Restoring diverse vegetation along the Atlantic seaboard after devastating hurricanes or replanting forests after destructive wildfires rests mightily upon one tiny but important ingredient: the seed.
	Study shows that rats will try to save members of their own species from drowning Rats have more heart than you might think. When one is drowning, another will put out a helping paw to rescue its mate. This is especially true for rats that previously had a watery near-death experience, says Nobuya Sato and colleagues of the Kwansei Gakuin University in Japan. Their findings are published in Springer's journal Animal Cognition.
	Mining pollution alters fish genetics in southwest England Pollution from historic mining activities in south west England has led to a reduction in genetic diversity of brown trout according to new research from the University of Exeter. The findings, which will be published on Friday 15 May in the journal Evolutionary Applications, indicate that human activity can alter the genetic patterns of wild populations - an important issue in modern conservation.
How the presence of conservation researchers affects wildlife In a study that compared three sites within the Dja Conservation Complex in Cameroon, Africa, investigators found that the presence of a conservation research project acts as a deterrent to chimpanzee and gorilla poachers, and community awareness and involvement in research lead to an increased value of apes and intact forests to local people, thus limiting hunting practices.
	Researchers develop new device to collect bed bugs In recent years, bed bugs (Cimex lectularius) have been appearing more and more often in beds around the world, and entomologists need specimens for research purposes.
Exogenous microRNAs in maternal food pass through placenta, regulate fetal gene expression In a new study published in the Protein & Cell, Chen-Yu Zhang's group at Nanjing University reports that small non-coding RNAs in maternal food can transfer through placenta to regulate fetal gene expression.
	Kissing cousins, arranged marriages and genetic diversity In the first study of its kind, a research team led by Massey University professor Murray Cox et al., in a publication in the advanced online edition of Molecular Biology and Evolution, has examined the effects of arranged marriages on genetic diversity.
	Using microbial communities to assess environmental contamination First there were canaries in coal mines, now there are microbes at nuclear waste sites, oil spills and other contaminated environments. A multi-institutional team of more than 30 scientists has found that statistical analysis of DNA from natural microbial communities can be used to accurately identify environmental contaminants and serve as quantitative geochemical biosensors. This study was sponsored by ENIGMA, a U.S. Department of Energy (DOE) Office of Science "Scientific Focus Area Program" based at the Lawrence Berkeley National Laboratory (Berkeley Lab).
Monkey farms in Florida under scrutiny from officials Tucked away in Florida's Hendry County, amid the scrub brush and saw palmetto grasslands just southwest of Lake Okeechobee, are three monkey breeding farms containing thousands of primates.
	Video shows mother bear rushing at tourists in Yellowstone Dramatic video captured by a Montana wildlife official shows a mother black bear with cubs running toward a knot of camera-clicking tourists as the animals try to cross a bridge in Yellowstone National Park.
	Seventeen endangered monkeys stolen from French zoo Two families of endangered monkeys were stolen from a zoo in central France over the weekend, the sanctuary's director told AFP late on Monday.
	European sturgeon research network established to boost prehistoric giants Sturgeons are among the most threatened fish species worldwide. To ensure that one day these living fossils will return to our rivers in large numbers, scientists have joined forces in a Europe-wide network. Seven partner institutions collaborate on research related to the conservation and development of stable sturgeon stocks and therefore pool their resources. In order to discuss a common strategy they all come together in Neu Wulmstorf on May 13th, 2015. The network has been initiated by the World Sturgeon Conservation Society (WSCS) and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin, a pioneer of the sturgeon reintroduction program for almost 20 years.
	Projects for sustainable fishing not effective enough Projects that stimulate sustainable fishing in developing countries often get no further than good intentions. Thus, some of the imported fish sold in European and North American shops may be less sustainably caught than claims suggest. To prevent the MSC quality label for sustainable fish catches being undermined, the requirements for market access should be made more exacting, argue Simon Bush from Wageningen University and his international colleagues in an article in Science published on 1 May.
	Feds approve wider testing of spinach defenses against citrus greening disease In a landmark step in the fight against citrus greening disease, the U.S. Environmental Protection Agency has approved Southern Garden Citrus' application for an Experimental Use Permit under the Federal Insecticide, Fungicide and Rodenticide Act.
