“The goal of AOCC is to improve the productivity and sustainability of highly nutritious crops that are critical to the health and livelihood of African farmers and consumers through the adoption of modern breeding methods,” Howard-Yana Shapiro, Chief Agricultural Officer, Mars, Incorporated.
On Jan. 10 at the 233rd American Astronomical Society meeting in Seattle, an international team of astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode.
Astronomers using NASA's Hubble Space Telescope have discovered the brightest object ever seen at a time when the universe was less than one billion years old. The brilliant beacon is a quasar, the core of a galaxy with a black hole ravenously eating material surrounding it. The quasar would have gone undetected without its light being turbo-boosted by the gravitational field of a closer galaxy that is bending and amplifying the distant quasar’s light.
The ALMA telescope is conducting an unprecedented survey of nearby disk galaxies to study their stellar nurseries. With it, astronomers are beginning to unravel the complex and as-yet poorly understood relationship between star-forming clouds and their host galaxies.
Rocky planets orbiting red dwarf stars may be dry and lifeless, according to astronomers using the Hubble telescope to study an eroding debris disk encircling the nearby star AU Microscopii. Life-nurturing ingredients, including water, may be blown away before they can reach young planets.
NASA's Hubble Space Telescope has produced this detailed portrait of the Triangulum galaxy (M33), displaying a full spiral face aglow with the light of nearly 25 million individually resolved stars. It is the largest high-resolution mosaic image of Triangulum ever assembled, composed of 54 Hubble fields of view spanning an area more than 19,000 light-years across.
Scientists at Tufts University have designed special LED “suits” that help them understand how caterpillars crawl. Versace might dress the likes of Shakira and Beyoncé, but Guy Levy designs for a far more unusual – and wriggly – client: the tobacco hornworm caterpillar (Manduca sexta).
Bats have long intrigued humans. In a variety of cultures, they embody malevolent symbolism, including darkness, death, foreboding, and evil spirits. In others, they’re benevolent flyers who bestow good fortune. Bats themselves also come in a variety of forms and shapes. The miniscule “bumblebee bat,” ranks among the world’s smallest mammals. Flying foxes, which eat mostly fruit and other vegetation, can have wingspans reaching up to 6 feet long. The clear-winged wooly bat may be one of the strangest to look at. Its wings are nearly transparent, and the muscles, circulatory system, and bones are clearly visible through the translucent, almost-paper-thin skin.
Just two years ago, the U.S. Embassy in Havana was bustling with U.S. personnel sent by the Obama Administration to restore diplomatic relations with Cuba. Today it is nearly empty. In late 2016, diplomats started hearing a loud, piercing noise. Two dozen of them reported symptoms such as ear pain and dizziness, and were diagnosed with injuries consistent with a concussion. Suspicions of politically motivated “sonic attacks” soon followed.
Climate change, pollution, and a multitude of threats are putting our freshwater supplies at risk. Water collection and purification technologies are becoming increasingly important, especially in major urban areas. In places such as the San Francisco Bay area, access to freshwater is limited. There, fog collection technologies have piqued the interest of many engineers looking to mediate the shortage of freshwater.
Artificial intelligence on Summit to discover atomic-scale structures.
Associate professor Dr. Gabriel Xu and Ph.D. candidate Ryan Gott are conducting research on plasma-based technology for water purification with funding from NSF EPSCoR CPU2AL.
Climate change could have devastating effects on vulnerable residents in the Andes mountains and the Tibetan plateau, according to researchers at The Ohio State University who have been studying glaciers in those areas for decades. Their findings—that glaciers in both parts of the world are melting more rapidly than at any point in the last 10,000 years—mean the water supply in parts of Peru, Pakistan, China, India and Nepal will decline, soon.
Farmers can already use drones to soar over huge fields and monitor temperature, humidity or crop health. But these machines need so much power to fly that they can't get very far without needing a charge. Now, engineers at the University of Washington have created a sensing system that is small enough to ride aboard a bumblebee.
Researchers at the University of New Hampshire have found unprecedentedly high levels of nitrate, an essential plant nutrient, in streams and watersheds of Puerto Rico for a year after two consecutive major hurricanes in 2017. This high amount of nitrate may have important climate change implications that could harm forest recovery and threaten ecosystems along Puerto Rico’s coastline by escalating algal blooms and dead zones.
Several presentations at the 2018 Society for Risk Analysis (SRA) Annual Meeting will explore novel approaches to monitoring real-time drug use in town and cities nationwide.
While most large corporations take responsibility for occupational risks, many partake in transferring these risks to smaller companies and the informal sector, where health risks are unrecognized and under-reported. More than half of the workers in many developing economies work in the informal sector where there are few, or no, workplace health protections.
During its Annual Meeting, the Society for Risk Analysis (SRA) announced the addition of five new Council members and the rise of Katherine McComas, Ph.D., Cornell University, as the new President of its 2019 Council. McComas succeeds Terje Aven, Ph.D., University of Stavanger, Norway, who has completed his term and will continue to serve on the Council as past-president.
In order to combat this issue, tools and practices need to be developed to help consumers and journalists filter the information they are constantly being fed.
The Society for Risk Analysis (SRA) is pleased to announce the winners for best papers in Risk Analysis: An International Journal and the best research posters for 2018.
Researchers from the University of Portsmouth have made vital contributions to the observations of four new gravitational waves, which were announced this weekend (1 December).
Risk assessment and risk mitigation practices can be beneficial in creating adaptation plans and making mitigation decisions for coastal communities. As scientists ponder the possibility of category six hurricanes, previous disaster prevention plans are no longer adequate for current threats from severe weather.
On Saturday, December 1, scientists attending the Gravitational Wave Physics and Astronomy Workshop in College Park, Maryland, presented new results from the National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European- based VIRGO gravitational-wave detector regarding their searches for coalescing cosmic objects, such as pairs of black holes and pairs of neutron stars. The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions. Six of the black hole merger events had been reported before, while four are newly announced.
Risk and benefit perceptions are crucial to people’s acceptance of a particular technology and therefore their willingness to become a consumer. It has been suggested that, due to resource restraints, consumers’ perceptions are frequently formed based on heuristics and biases, or other factors such as trust or affect.
The 60th Annual Meeting of the American Society of Hematology will feature research from St. Jude Children’s Research Hospital on topics ranging from the genomic basis and vulnerabilities of leukemia to an update on gene therapy for hemophilia B to advances in sickle cell disease and beta-thalassemia.
Simulating any 3D surface or structure--from tree leaves and garments to pages of a book--is a computationally challenging, time-consuming task. While various geometric tools are available to mimic the shape modeling of these surfaces, a new method is making it possible to also compute and enable the physics--movement and distortion--of the surface and does so intuitively and with realistic results.
Ruth Lehmann, chair of the Department of Cell Biology and director of the Skirball Institute of Biomolecular Medicine at New York University, has been chosen to present the Keith Porter Lecture on Sunday, December 9, at 3:15 pm at the 2018 ASCB|EMBO Meeting in San Diego.
Researchers are exploring how irregular filling mechanics may contribute to defects in developing fetal hearts because inefficient filling leads to energy losses that alter the heart’s structure and performance, and studying how filling mechanics and flow structure change over the course of gestation. During the American Physical Society’s Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, they will discuss the team’s findings on human fetal cardiac flow measurements collected from normal and abnormal fetal echocardiogram exams.
In aquaponics, the hydroponic crops use the nutrients from fish waste as fertilizer while the fish benefit from the plants’ nutrient uptake capability to improve water quality. The treated water is then recirculated to the plant grow beds and fish culture tanks via a pipe system. Researchers at the University of New Hampshire, who are studying ways to improve water flow for more efficient aquaponic systems, will present their work at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.
As professional divers complete what’s known as a rip dive, their hands remove water in front of the body, creating a cavity that reduces the initial impact force. The rest of the body is aligned to shoot through the same cavity created by the hands. Using the hands to create cavities in the water's surface is similar to the concept behind the fluid-structure studies that researchers at Utah State University are conducting using spheres. They’ll present their work at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.
Ever watch aquatic animals jump out of the water and wonder how they manage to do it in such a streamlined and graceful way? Researchers who specialize in water entry and exit in nature had the same question. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, they will present their work designing a robotic system inspired by jumping copepods and frogs to illuminate some of the fluid dynamics at play when aquatic animals jump.
A geology professor at the University of Nevada, Las Vegas, has discovered that a set of 28 footprints left behind by a reptile-like creature 310 million years ago, are the oldest ever to be found in Grand Canyon National Park.
Wok tossing is essential for making a good fried rice -- or so claim a group of researchers presenting new work at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20. The researchers became interested in the physics of cooking and, seeking to satiate their curiosity, they focused on stir-fry, which lies at the heart of Chinese cuisine. The team set out to isolate the key elements of this venerable cooking technique.
Some animals explore, interpret and understand the world with such sensitivity in their noses that people have enlisted canines to help solve crime and detect cancer on the breath. Scientists at Georgia Tech are now homing in on the secrets behind animals’ super sniffers to develop an artificial chemical sensor that could be used for a variety of tasks, from food safety to national security. Thomas Spencer will present the group’s latest design for an electronic nose that concentrates odors for improved chemical sensing at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.
Motivated by observations of desert flora and fauna, researchers in Arizona began experimenting in the laboratory to characterize cactuses' microscopic 3D epidermal structure at dry and wet times of the year. They apply the lessons in wettability -- the study of how droplets interact with solids -- to engineering surfaces for industrial applications, and will present the discoveries from this Sonoran wettability research at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.
Urinating into a cup may be a medical necessity at times, but it's often uncomfortable, embarrassing and messy -- especially for women. But what if there were a way to comfortably provide a sample without the splashback? Researchers have created a set of experiments using an anatomically correct female urethra that produced a jet of water with a pressure and flow equivalent to a human bladder. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, they’ll describe the findings and potential implications.
Nature is full of examples of large-scale collective behavior; humans also exhibit this behavior, most notably in pelotons, the mass of riders in bicycle races. Using aerial video footage of bicycle races, researchers analyzed peloton motion to determine what causes changes in the group’s large-scale collective behavior and found that riders move through the peloton in a manner similar to circulation in a fluid. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, they will describe their work on collective behavior in pelotons.
Marvel comics superheroes Ant-Man and the Wasp possess the ability to temporarily shrink down to the size of insects, while retaining the mass and strength of their normal human bodies. But a new study suggests that, when bug-sized, Ant-Man and the Wasp would face serious challenges, including oxygen deprivation. Those challenges, along with their solution-microfluidic technologies, will be described at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.
Wombats are central to a biological mystery in the animal kingdom: How do they produce cube-shaped poop? Patricia Yang at Georgia Tech set out to investigate. Yang studies the hydrodynamics of fluids, including blood, processed food and urine, in the bodies of animals. She was curious how the differences in wombats’ digestive processes and soft tissue structures might explain their oddly shaped scat. During the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20, Yang will explain findings from dissecting the alimentary systems of wombats.
An unexpected twist from fastball can make the difference in winning or losing the World Series. However, “some explanations regarding the different pitches are flat-out wrong,” said Barton Smith, a professor of mechanical and aerospace engineering at Utah State University who considers himself a big fan of the game. He and Nazmus Sakib are conducting experiments to explain how baseballs move. Sakib and Smith will present their findings at the APS Division of Fluid Dynamics 71st Annual Meeting, Nov. 18-20.
Researchers from the Green IC research group at the National University of Singapore have invented a low-cost ‘battery-less’ wake-up timer – in the form of an on-chip circuit – that significantly reduces power consumption of silicon chips for Internet of Things sensor nodes.
Indiana University has joined in endorsing the Paris Call for Trust and Security in Cyberspace, a document calling for international cooperation in the realm of cybersecurity, presented today by French President Emmanuel Macron at the Paris Peace Forum.
Beatboxing is a musical art form in which performers use their vocal tract to create percussive sounds, and a team of researchers is using real-time MRI to study the production of beatboxing sounds. Timothy Greer will describe their work showing how real-time MRI can characterize different beatboxing styles and how video signal processing can demystify the mechanics of artistic style. Greer will present the study at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
Few things can delight an adult more easily than the uninhibited, effervescent laughter of a baby. Yet baby laughter, a new study shows, differs from adult laughter in a key way: Babies laugh as they both exhale and inhale, in a manner that is remarkably similar to nonhuman primates. The research will be described by Disa Sauter during a talk at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
Hearing has long been suspected as being "on" all the time -- even in our sleep. Sounds that occur during the night have a way of registering in the brain. Now scientists are reporting results on what is heard and not heard during sleep and what that might mean for a developing brain. At the Acoustical Society of America's 176th Meeting, Nov. 5-9, researchers from Vanderbilt University will present preliminary results from a study in which preschool children showed memory traces for sounds heard during nap time.
Here's another reason you might be exhausted after that preschool birthday party: Your brain had to work to figure out who actually asked for more ice cream. "What we found with two-and-a-half-year-olds is that it's amazingly hard for adults to identify who's talking," said Angela Cooper, a postdoctoral researcher at the University of Toronto. Cooper's co-authored research will be presented in the poster session at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
To find ways to improve man-made active sensing, scientists worldwide study the sonar systems of bats and dolphins. During the Acoustical Society of America's 176th Meeting, Nov. 5-9, Laura Kloepper will compare bat and dolphin sonar systems, describing her work on how the two animals cope with acoustic interference. She'll use her findings to argue why bats have the superior system.
