Controlling bubble formation on electrodes
Using electricity to split water into hydrogen and oxygen can be an effective way to produce clean-burning hydrogen fuel, with further benefits if that electricity is generated from renewable energy sources. But as water-splitting technologies improv.....»»
Research shows bone density is maintained by proteins that are also involved in hair color
Bone is maintained via a delicate balance between formation and resorption, and its imbalance leads to bone related diseases like osteoporosis, rheumatism and periodontitis......»»
Measuring mechanical stresses and strains in graphene-based supercapacitor electrodes
Texas A&M University researchers have discovered that when charging a supercapacitor, it stores energy and responds by stretching and expanding. This finding can be used to design new materials for flexible electronics or other devices that must be b.....»»
Astronomers capture formation of a powerful cosmic jet
Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma from a supermassive black hole. The jet travels at nearly the speed of light and shows complex, twisted patterns near.....»»
Lysosomes prove to be quick-change artists with respect to nutrient availability in the cell
Lysosomes play an important role in cells and tissues, controlling not only the degradation of substances but also cell division and growth. A team led by Professor Volker Haucke and Dr. Michael Ebner at the FMP has investigated how these two functio.....»»
Global sea-level fall led to formation of Ediacaran-Cambrian unconformity in North China Craton, finds study
In many blocks on the Earth, the boundary between the Phanerozoic and Precambrian is consistently characterized by a huge sedimentary gap—the Great Unconformity......»»
How mosquito-controlling bacteria might also enhance insect fertility
A new study reveals biological mechanisms by which a specific strain of bacteria in the Wolbachia genus might enhance the fertility of the insects it infects—with potentially important implications for mosquito-control strategies. Shelbi Russell of.....»»
A new versatile tool for studying fish hormones may transform fish farming
Dr. Itamar Harel, along with Ph.D. student Eitan Moses and postdoctoral researcher Dr. Roman Franek, all from the Hebrew University of Jerusalem, has introduced an innovative platform for controlling peptide hormones in fish, providing a fast and eff.....»»
This 3D-printed plate lets food droplets magically move without being touched
New "computational food" design incorporates electrowetting on dielectric technology. "Dancing Delicacies": Researchers at Monash University created a special plate enhanced with electrodes that moves liquid droplets ar.....»»
Does urbanization trigger plant evolution?
Urbanization and human activities have transformed a significant proportion of the land on Earth, resulting in the formation of urban environments. These urban environments are man-made habitats that often impose several selective pressures on their.....»»
Modulation of protein stability: A new approach to studying cosolvent effects
Controlling the process of destabilization is important when manipulating the unfolding and refolding of proteins in vitro (outside their native environment). To this end, urea and alcohol are used as cosolvents, substances added in small amounts alo.....»»
Enzyodynamic therapy at nanoscale
Enzyodynamic therapy (EDT) is a new type of reactive oxygen species (ROS)-related dynamic therapeutic modality, which adequately utilizes the enzyme-triggered catalytic reactions in living organisms and achieves disease treatment through controlling.....»»
New observations confirm important step in star formation
New observations have confirmed a key step in the process of star formation: a rotating "cosmic wind" made of molecules, which is vitally important for collapsing gas clouds to contract sufficiently so as to form a hot, dense young star......»»
Scientists explain unique formation of ancient algae that evolved photosynthesis and oxygenated the planet
Scientists have for the first time revealed how blue-green algae—visible as the slippery green slime in stagnant water, riverbeds, and seashores—weaves itself into large weblike structures......»»
Scientists reveal centromere repositioning in soybean genome
Researchers from China studying soybean genome evolution have focused on the phenomenon of centromere repositioning, which involves the formation of new centromeres at different chromosomal locations without altering the underlying DNA sequences. Thi.....»»
Planet collision explains star’s brightening, then dimming
Emissions in infrared shot up, then visible light dropped two years later. Enlarge / Artist's conception of what the post-collision body of material might look like. (credit: MARK GARLICK) Planet formation is thought to.....»»
NASA asteroid sample contains life-critical water and carbon
A sample collected from the 4.5-billion-year-old asteroid Bennu contains abundant water and carbon, both vital materials for the formation of our planet, NASA revealed on Wednesday......»»
Study shows wild pig populations in US can be managed
Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research from the University of Georgia's Savannah River Ecology Laboratory and Warnell School of Forestry and N.....»»
Remnant of cell division could be responsible for spreading cancer
Once thought to be the trash can of the cell, a little bubble of cellular stuff called the midbody remnant is actually packing working genetic material with the power to change the fate of other cells—including turning them into cancer......»»
Astronomers discover first step toward planet formation
Solving the mystery of how planets like Earth were formed is an important question for understanding the origin of life. Planets are thought to form when interstellar dust and gas collect in a protoplanetary disk surrounding a protostar, but it has b.....»»
6 things to know about NASA"s asteroid-exploring Psyche mission
The first-ever mission to study a metal-rich asteroid, Psyche aims to help scientists learn more about the formation of rocky bodies in our solar system......»»
