Some of the natural gas harvested by hydraulic fracturing operations may be of biological origin—made by microorganisms inadvertently injected into shale by oil and gas companies during the hydraulic fracturing process, a new study has found.
New research shows a cereal familiar today as birdseed was carried across Eurasia by ancient shepherds and herders laying the foundation, in combination with the new crops they encountered, of 'multi-crop' agriculture and the rise of settled societies. Archaeologists say 'forgotten' millet has a role to play in modern crop diversity and today's food security debate.
Brain cancer is not cellular anarchy, says Pedro Lowenstein and colleagues at the University of Michigan and University of Arizona, but highly organized—self-organized. At ASCB 2015, the researchers report that glioma cells build tumors by self-organizing into streams,10-20 cells wide, that obey a mathematically predicted pattern for autonomous agents flowing together. These streams drag along slower gliomas, may block entry of immune cells, and swirl around a central axis containing glioma stem cells that feed the tumor’s growth.
Chronic obstructive pulmonary disease (COPD )is the third leading cause of death in the US and cigarette smoking is the leading cause of COPD. Currently there is no cure, current treatments are largely palliative, and new treatment targets are scarce. Now Corrine Kliment and colleagues in Doug Robinson’s lab at Johns Hopkins University have found two new targets for blocking cigarette smoke-induced COPD in a surprising place—amoebas. Kliment presents the work at ASCB 2015.
University of Washington researchers have reconstructed 3-D models of celebrities such as Tom Hanks from large Internet photo collections. The models can deliver speeches that the real actor never performed - one step toward developing fully interactive digital models of people from family or historic photo collections.

Along coastlines from California to Australia, you'll see surfers trying to catch that perfect wave. How they find and ride that wave relies on feel and intuition, developed through skill and experience. Now researchers from the LadHyX Hydrodynamics Laboratory of École Polytechnique in France are trying to quantify this ability, studying the conditions necessary for a surfer to catch a wave. They'll present their findings at APS's DFD 2015 Meeting.
Simply oscillating its fins is all a flounder, a flat fish, needs to do to resuspend sand and quickly disappear beneath it to hide. By discovering the physics at play, researchers in France are hoping to provide a new flounder-inspired solution to a common technological challenge: the resuspension of granular material within a fluid. They'll discuss their findings at the American Physical Society's 2015 DFD Meeting.
In the fleeting moments after a liquid is subjected to a sudden change in pressure, microscopic bubbles rapidly form and collapse in a process known as cavitation. In the human brain, this is believed to be a mechanistic cause of traumatic brain injury, or TBI, but the phenomenon has yet to be directly observed in brain tissue because the bubbles appear and disappear within microseconds. To address this, researchers are seeking to understand how cavitation might injure neurons by using a 3-D imaging system coupled with a diffraction grating to examine their post-exposure morphology. They will present their recent findings APS’s DFD 2015 Meeting.
Last year Italy sent an espresso machine up to the ISS, and this inspired a team of researchers to study the related strange fluids phenomena in low gravity, such as espresso crema formation and containment of potentially hazardous drinks within a spacecraft. To do this, the researchers designed a cup that exploits surface tension as opposed to gravity and during APS’s DFD Meeting they'll present their findings about how it's working aboard the Space Station.
Have you ever wondered why insects move in the funky ways they do? Or how physical laws shape the design of animals' sensors and neural computation for locomotion? These are a just a few of the questions Cornell University researchers are exploring within this realm, and during APS’s DFD 2015 Meeting, Z. Jane Wang, a Professor of Physics and of Mechanical and Aerospace Engineering, and one of her students, James Melfi Jr., will share their findings.
Monday, Nov. 23: A Live Streamed Event on the Physics of Surfing, the Complex Secrets of the Sneeze, a Flounder’s Disappearing Act, and How Fur Keeps Animals Warm in Cold Water -- News from the 68th Annual Meeting of APS Division of Fluid Dynamics in Boston
However commonplace it may be in human life, the sneeze remains somewhat of an enigma to science, and we are still a long way from understanding the simple sneeze in all its phlegm-flam glory. This month during APS’s DFD 2015 Meeting, researchers will present new work that shows how droplets are formed within a high-propulsion sneeze cloud -- a critical piece of the puzzle that has so far been missing.
Rather than relying on a thick layer of body fat for insulation as many aquatic mammals do, some seabirds and semiaquatic mammals such as fur seals and otters trap a layer of air in their feathers and furs for thermal insulation against the ice cold drink. Now a team of researchers from MIT has experimentally studied the trapping of air in hairy surfaces and the water-repellent properties of undeformable hairy textures, which is key for animals’ thermal regulation. The researchers will present the study at APS’s DFD Fall 2015 Meeting.
Antarctic penguins live in a bitterly cold place, where the air temperature can drop to -40 degrees Celsius and the winds can hurtle at speeds of 40 meters per second. Although these birds routinely hop in and out of the water in sub-freezing temperatures, they manage to keep ice from coating their feathers. Now researchers have examined penguin feathers in extreme detail and think they know the penguins' anti-icing trick: a combination of nanostructures and a special oil make Antarctic penguin feathers ultra-water-repelling, or superhydrophobic. The researchers will present their findings at APS's DFD Fall 2015 Meeting.
Drifting snow is a complicated and poorly understood process that is important to fathom because it accounts for a major fraction of wind-blown snow redistribution within polar and mountainous regions of the world. To understand it better, a group researchers is exploring mass and momentum fluxes during drifting snow events, pursuing an improved understanding of the link between snow cover erosion and deposition. They will present their findings at APS’s DFD 2015 Meeting.

Organized extracurricular sport activities for children help them develop and improve cognitive skills, such as greater concentration capacity, that can in term greatly help them in the classroom, says Université de Montréal professor Linda Pagani.
Concerts held within Hanoks are popular tourist attractions in Korea, and when a team of researchers from Soongsil University in Seoul discovered this, they set out to explore whether the homes’ excellent acoustics stem from their architectural structure as well as materials. During ASA’s Fall 2015 Meeting, being held Nov. 2-6, in Jacksonville, Fla., the team will describe their findings analyzing the harmony that results from playing traditional instruments within Hanoks.
While scientists are still investigating the causes of colony collapse disorder, beekeepers could benefit from technologies that help them track the health of their hives, and researchers have developed a device that can monitor hive activity without disturbing the bees. It picks up and analyzes vibrations from special types of bee vocalizations and has successfully tracked changes in bee activity from day to night, and seasonally, by monitoring the occurrences of this specific signal. The team will present their results at ASA’s Fall 2015 Meeting.
A Himalayan singing bowl operates like a wine glass -- slide your fingertip, or a wooden stick called a puja, around its rim to hear its soothing tones. The bowls have been used for meditation and worship for centuries, but have found new audiences in contemporary music. Researchers have studied the motion of the bowl and revealed the origin of “chatter,” which occurs when the puja is played against the bowl. The study will be presented at ASA’s Fall 2015 Meeting.
Researchers have found an alternative choice for songbird study: a small non-migratory songbird commonly found in North America known as the black-capped chickadee. Female black-capped chickadees sing and their songs are acoustically distinct from the songs of their male counterparts. What’s more, the researchers say, both male and female birds can tell apart the songs of the two sexes. Sturdy will describe the new findings in a talk at ASA’s Fall 2015 Meeting.
Utah Valley University physicists are literally applying rocket science to the field of medical diagnostics. With a few key changes, the researchers used a noninvasive ultrasonic technique originally developed to detect microscopic flaws in solid fuel rockets to successfully detect cell stiffness changes associated with certain cancers and other diseases. Brian Patchett will describe the group’s method, which uses sound waves to manipulate and probe cells, during ASA’s Fall 2015 Meeting.
New evidence gathered from the Karoo Basin in South Africa sheds light on a catastrophic extinction event that occurred more than 250 million years ago and wiped out more than 90 percent of life in Earth’s oceans and about 70 percent of animal species on land.
Researchers have examined the relationship between the sound structures of a worldwide sample of human languages and climatic and ecological factors including temperature, precipitation, vegetation and geomorphology. The results, to be presented at ASA’s 2015 Fall Meeting, Nov. 2-6, show a correlation between ecological factors and the ratio of sonorant segments to obstruent segments in the examined languages. This supports the hypothesis that acoustic adaptation to the environment plays a role in the evolution of human languages.
The Asian Citrus Psyllid is loathed by orange farmers because they spread an even more pernicious foe: the bacteria Candidatus Liberibacter asiaticus, which cause a disease called citrus greening that turns the trees' leaves a sickly yellow and makes the fruit bitter and stunted. There is no cure, and the infected trees usually die within a few years. To halt the spread of the disease, researchers are developing vibration traps that hijack psyllid mating calls to locally bring their populations under control.
We all love belting our lungs out at sporting event, hurling insults and encouragements in turn, but does it actually have an effect on either team’s performance? A study conducted by a student at the University of Nebraska seeks to answer this question. The study was performed by Brenna Boyd, an undergraduate research assistant at the University of Nebraska-Lincoln’s. Boyd will present her findings at ASA’s Fall 2015 Meeting.
