	Image: SOHO captures bright filament eruption An elongated solar filament that extended almost half the sun's visible hemisphere erupted into space on April 28-29, 2015, in a large burst of bright plasma. Filaments are unstable strands of solar material suspended above the sun by magnetic forces. Solar astronomers around the world had their eyes on this unusually large filament and kept track as it erupted. Both of the coronagraph instruments on the joint ESA/NASA Solar and Heliospheric Observatory, or SOHO, show the coronal mass ejection associated with the eruption.
	Opportunity of a lifetime—NASA's 4,000 days roving Mars NASA's exploration rover Opportunity landed on Mars more than 11 years ago, in January 2004, with what then seemed like ambitious goals: to survive 90 Martian days and drive 600 metres. Opportunity has since driven the first off-Earth marathon (42.2 kilometres, or just over 26 miles) and just passed through its 4,000th Martian day – known as a sol on the Red Planet, lasting 40 minutes longer than on Earth.
	Key facts and timeline for SpaceX crewed Dragon's first test flight, May 6 The first critical test flight of SpaceX's crewed Dragon that will soon launch American astronauts back to orbit and the International Space Station (ISS) from American soil is now less than two days away.

Technology news

	Footage from drone perspective with CyPhy Works Sometimes you hear enthusiasts talking about high-quality footage. Now the chatter can shift over to discussions about quality drone footage. The good news is that a talented team has come up with a concept for taking pictures with a drone which would not require advanced skills and expensive equipment. It is no accident that a promotional video for a video-capturing drone shows a child, not an adult, holding up the phone. Fast Company said, "CyPhy Works has so far focused on developing drones for commercial and emergency responder-type uses. Now it wants to sell to everyone." CyPhy Works in Danvers, Massachusetts, founded by iRobot co-founder Helen Greiner, has been making tethered drones for industrial application. These drones were designed to fly 24/7 in all types of wind and weather.

	Pressure-monitoring stockings to prevent wounds in diabetics Diabetics often have little feeling in their feet and don't perceive the body's pressure or temperature signals there. This can result in unnoticed wounds that then develop into abscesses. Many diabetics have to have toes or feet amputated. Now, a novel kind of pressure stocking developed by Fraunhofer researchers is set to help protect against wounds via an integrated sensor system that sends a warning when pressure is too high. The new pressure-monitoring stocking prototype will be presented May 19-21 at SENSOR+TEST 2015 in Nuremberg.
	The downside of biodiesel fuel The oil industry believes biodiesel is not to blame for problems that Norwegian car owners are experiencing. But the nature of the fuel means that it has to be handled differently than regular petroleum-based diesel, a Norwegian researcher says, especially in colder climates or if it is stored for longer periods.
	Researchers design new tiny QWERTY soft keyboards for wearable devices There is a growing number of wearable devices featuring touchscreens, including smart watches, smart glasses and digital jewellery. These devices can receive notifications in many forms, but usually there is no direct way of replying, since they lack a text entry system, mainly because the space available onscreen is very limited. Now, a team of researchers from the Universitat Politècnica de València and the University of Stuttgart have developed two tiny QWERTY soft keyboard prototypes, which enable users to answer or enter text on their wearable devices.
	High-tech sensors help kids keep eye on aging parents Each time 81-year-old Bill Dworsky or his 80-year-old wife Dorothy opens the refrigerator, closes the bathroom door or lifts the lid on a pill container, tiny sensors in their San Francisco home make notes on a digital logbook.

	Brain in a bottle: A new culture medium for growing and testing neuronal cells in vitro (Phys.org)—In vivo neural electrical activity is the essence of nervous system function, controlling sensory modalities, emotion, memory, behavior, and basic survival functions. Therefore, to study neurons in the laboratory it is important that in vitro neuronal models also support such electrical activity to reflect fundamental brain functions – and most human neuronal cultures are currently grown in vitro using the classic culture media DMEM (Dulbecco's Modified Eagle Medium), Neurobasal, or a mixture of the two. In contrast, laboratory experiments employing electrophysiological techniques – such as patch clamping (which allows the study of single or multiple ion channels in cells), calcium imaging – on brain slices or in culture are performed in a medium of artificial cerebrospinal fluid (aCSF).
	Researchers examine how the brain and body respond to glucose and fructose When it comes to sweeteners, one indulgence makes our brains predisposed to do it, according to a new study by researchers at Keck Medicine of USC.
	Blocking obesity-associated protein stops dangerous fat formation Visceral fat deposits around internal organs in the stomach are particularly harmful: they are associated with insulin resistance, type-2 diabetes and heart disease. The study, conducted in close collaboration with researchers at the at the French Institute of Health and Medical research (INSERM) in Paris, shows that changing the pattern of fat deposition from around the stomach to under the skin starts a chain of events which result in insulin sensitivity being maintained, reducing the chances of type-2 diabetes.
	Smartphone study reveals a change in how we remember as we get older As we get older we can hold less information in our minds. Whereas 16 to 17 year-olds can hold an average of 6.5 numbers in mind for a short time in their "working memory", this drops to five numbers for 75 to 79 year-olds.
	Researchers compare neurons in optic nerves to find why some regenerate and others don't It's a question that seems to offer tantalizing hope to those suffering from vision impairment.

	Study reveals evolutionary history of hawkmoths' sonar jamming defense In the 65-million-year-old arms race between bats and moths, some moth species rub their genitals to jam the calls of bats. Radar jamming is commonly used in human warfare, allowing pilots to render themselves invisible. By unraveling the evolution of hawkmoths' similar defense, authors of a new study appearing online this week in the Proceedings of the National Academy of Sciences aim to better understand nocturnal biodiversity and improve human uses of sonar.
	The media is the message: How stem cells grow depends on what they grow up in Human pluripotent stem cells (hPSCs) possess the ability to grow into almost any kind of cell, which has made them dynamic tools for studying early human development and disease, but much depends upon what they grow up in.
	Blue whales lack the ability to avoid cargo ships, says biologist For millions of years, blue whales have cruised the world's oceans with hardly a care, their sheer size making them largely free from predator attacks. The downside to being the largest animals in history, however, is that the species was never pressured to evolve defensive behaviors.
	Just like humans, dolphins have social networks They may not be on Facebook or Twitter, but dolphins do, in fact, form highly complex and dynamic networks of friends, according to a recent study by scientists at Harbor Branch Oceanographic Institute (HBOI) at Florida Atlantic University. Dolphins are known for being highly social animals, and a team of researchers at HBOI took a closer look at the interactions between bottlenose dolphins in the Indian River Lagoon (IRL) and discovered how they mingle and with whom they spend their time.
	Researchers report possible discovery of sixth DNA base, methyl-adenine DNA (deoxyribonucleic acid) is the main component of our genetic material. It is formed by combining four parts: adenine, cytosine, guanine and thymine (A, C, G and T), called bases of DNA. They combine in thousands of possible sequences to provide the genetic variability that enables the wealth of aspects and functions of living beings.
	How does a mobile DNA sequence find its target? To understand how transposable elements shape genomes, where they are maintained over generations, it is vital to discover the mechanisms behind their targeted integration. Researchers from the Laboratoire Pathologie et Virologie Moléculaire (CNRS/Inserm/Université Paris Diderot), in collaboration with researchers from CEA and a US laboratory, have identified an interaction between two proteins that is essential for the integration of a transposable element into a specific area of the yeast genome. These results, published on 1 May 2015 in the journal Science, emphasize the role of these mobile DNA sequences in the evolution and adaptation of organisms, and their potential value for gene therapy.
	Student dig uncovers hundreds of rare moa bones Māori Studies staff and students from Victoria University of Wellington have excavated hundreds of moa bones from a central North Island site where few moa remains were known to exist.
Researchers bombard plant-killing fungus with silver nanoparticles Deep in the soil, underneath more than 400 plant and tree species, lurks a lethal fungus threatening Florida's $15 billion a year ornamental horticulture industry.
	Australia—riding on the insect's back As you may have spotted, the title of this article is a cheeky reference to the famous saying that Australia rides on the back of a particular woolly ruminant. The reference dates back to 1894, when the wool industry was one of the primary sources of Australia's prosperity.
How mixing light with salt makes a smolt? For decades, researchers have tried to find out what regulates changes in salmon when they transform from being freshwater to saltwater fish. Now they have come a little closer to an answer.
	Tough laws 'not enough' to stop endangered wildlife trade The international wildlife trade is a major threat to various endangered animals across the world, but as western conservation groups seek stricter law enforcement over this practice, new research finds that tough laws are "not enough" to stomp out the trade.
	Fire linked to dieback spread Fire has the potential to increase the range and severity of Phytophthora dieback in native plant communities infected with the disease, suggests a study at the Stirling Range National Park near Albany.
	Hitting the borders of expansion Why does a species not adapt to an ever-wider range of conditions, gradually expanding its geographical range? In their paper published on May 5 in PNAS (Proceedings of the National Academy of Sciences), Jitka Polechova and Nick Barton at the Institute of Science and Technology Austria (IST Austria) seek to answer this question, which lies at the interface between ecology and evolution. The theory presented by Polechova and Barton suggests that any natural population is liable to form sharp margins.
Research charts a course for increasing edamame acreage in the Midwest While consumer demand for edamame or vegetable soybean remains on the rise in the United States, it's not widely grown in this country. Nearly 85 million acres of grain-type soybean were grown in the U.S. in 2014, yet edamame imported from Asia appears to dominate what we eat in this country, said a University of Illinois crop scientist.
	New technology maps human genome in days The two 3-by-1-inch glass chips held the unfathomable amount of genetic information contained in 16 human genomes. Last week, a technician placed the chips - called flow cells - in a new genetic sequencing machine at the Genome Institute at Washington University and closed the door.
	Behind the scenes with a Los Angeles mountain lion expert When LA's Griffith Park mountain lion crawls under someone's house, or a brother-and-sister pair become the first mountain lions with tracking collars to cross a freeway since 2009, Seth Riley is at the top of the list of scientists who can answer the questions everyone's asking. Why would a mountain lion nap in a crawl space? Do mountain lions often go into residential areas? How hard is it for a mountain lion to cross a Los Angeles area freeway?
	Veterinarian offers advice for keeping your dog safe from canine flu With the large outbreak of canine influenza in the Midwest making headlines, many pet owners are understandably worried about the disease. The virus has reportedly sickened more than 1,000 dogs and killed at least five pets in Illinois, Wisconsin, Ohio and Indiana.
	Anaerobic co-digestion of farm-based manure, food waste, are there benefits vs. landfilling? Based on a comprehensive life cycle analysis comparing the environmental impacts and economic outcomes for managing manure and food waste produced on a dairy farm, researchers found that anaerobic co-digestion of the waste products had substantial cost, energy, and environmental benefits compared to digestion of manure but disposal of food waste in a landfill. A detailed discussion of the potential for bioenergy production, increased profitability, and reductions in global warming and smog is presented in an original research article in Industrial Biotechnology.
	Norway plans to slash subsidies to fur farms Norwegian fur farmers denounced Tuesday a government proposal to slash financial support to the controversial industry and warned that it could lead to farm closures in vulnerable rural areas.
