Methane "gobbling" microorganism is a shape shifter
A microorganism that helps reduce the release of the greenhouse gas methane into the atmosphere has been found to be a "shape shifter" capable of markedly changing its appearance and metabolism to rapidly respond to changes in its environment, a team.....»»
Telescopes show the Milky Way"s black hole is ready for a kick
The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that can look like a football, according to a new study using data from NASA's Chandra X-ray Observatory and the.....»»
Biotrickling filter supports efficient hydrogen-methane conversion for biological biogas upgrading
Biological hydrogen-methane conversion refers to the production of methane through the action of microorganisms using hydrogen generated by electrolysis of water with residual power and carbon dioxide present in biogas. This approach promises to over.....»»
Building a DNA nanoparticle to be both carrier and medicine
Scientists have been making nanoparticles out of DNA strands for two decades, manipulating the bonds that maintain DNA's double-helical shape to sculpt self-assembling structures that could someday have jaw-dropping medical applications......»»
Small satellite may shape centaur rings
The unique two thin rings around the Centaur Chariklo could be shaped by an even smaller satellite. Chariklo is a Centaur, which are small bodies similar to asteroids in size but to comets in composition, that revolve around the sun in the outer sola.....»»
Plan for Europe"s huge new particle collider takes shape
Europe's CERN laboratory revealed more details Monday about its plans for a huge new particle accelerator that would dwarf the Large Hadron Collider (LHC), ramping up efforts to uncover the underlying secrets of the universe......»»
Study shows marine heat waves have significant impact on microorganisms
A new study led by Australia's national science agency, CSIRO, shows that marine heat waves (MHWs) are altering the microorganism communities that form the base of the marine food chain, disrupting coastal ecosystems. The article "A marine heat wave.....»»
A type of plastic that can be shape-shifted using tempering
A team of molecular engineers have developed a type of plastic that can be shape-shifted using tempering. In their paper published in the journal Science the team, from the University of Chicago, with a colleagues from the US DEVCOM Army Research Lab.....»»
How to speed up your Mac and get it back into shape
If your Mac has slowed down, don’t panic. There are plenty of ways you can speed it up again, and our handy guide will show you all the best ways to do so......»»
Hubble captures a suspected galaxy encounter
UGC 3912 is classified as a spiral galaxy, but you wouldn't know it from this detailed NASA Hubble Space Telescope image. UGC 3912's distorted shape is typically indicative of a gravitational encounter with another galaxy. When galaxies interact—ei.....»»
Improving Arctic greenhouse gas sink and source estimates with field measurements, remote sensing
A new study investigates the sinks and sources of key greenhouse gases of carbon dioxide, methane, and nitrous oxide in the Arctic landscape with a spatial resolution of only a few square meters. Vegetation and soil conditions explain the differences.....»»
New research brings order to disordered proteins
Protein molecules lie at the heart of biology. Our typical understanding of proteins states that each type of protein has a specific three-dimensional shape that enables it to perform its function. This dogma is challenged by intrinsically disordered.....»»
Researchers use simulations to tackle finite sphere-packing problem and "sausage catastrophe"
Have you ever wondered about the best way to pack a finite number of identical spheres into a shape-shifting flexible container, like a convex hull?.....»»
New study reports that Greenland is a methane sink rather than a source
Researchers at the University of Copenhagen have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland. The results of the new study contribute important knowledge to climat.....»»
When dissipative solitons vanish, breathing dynamics occur: Study
Solitons are quasiparticles that propagate along a non-dissipative wave. Put another way, they are waveforms that hold their shape as they move—like a single wave moving across the surface of a pond. They can also show particle-like behavior, such.....»»
Researchers discover molecular mechanism that influences the symmetrical shape of the style
Humans are attracted to symmetry: in our buildings, our gardens, in our potential partners. For plants, the symmetrical shapes of organs are a matter of survival because the form directly impacts the function......»»
Study predicts best times for Curiosity to sample Mars" methane
Since methane was first detected in Mars' atmosphere 20 years ago, scientists have struggled to uncover its origins and how it is transported around the Red Planet. Measurements from atmospheric samples collected by NASA's Curiosity rover at Gale cra.....»»
Study tracks how wetland tree stem emissions vary by season, location, and hydrological conditions
The recent rise in atmospheric methane (CH4) has drawn increased attention to the potent greenhouse gas, which is approximately 45 times more powerful than carbon dioxide at trapping heat in the atmosphere. About 60% of global methane emissions are a.....»»
Coastal chemistry improves methane modeling
Scientists at Oak Ridge National Laboratory are using a new modeling framework in conjunction with data collected from marshes in the Mississippi Delta to improve predictions of climate-warming methane and nitrous oxide emissions from soils in coasta.....»»
Hubble views NGC 3384, a galaxy settling into old age
NGC 3384, visible in this image, has many of the characteristic features of so-called elliptical galaxies. Such galaxies glow diffusely, are rounded in shape, display few visible features, and rarely show signs of recent star formation. Instead, they.....»»
Microwave detectors and multiplexing: Researchers help astronomers examine the early universe
Perched atop a high plateau in Chile's Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes devoted to studying the oldest light in the universe: radiation left over from the Big Bang......»»
