Chemists develop chameleon-like molecular chain with dual ion binding capability
Everyday objects such as metal chains, handcuffs, and key rings are examples that demonstrate a unique combination of properties where hard, rigid rings are interlocked together to exhibit flexibility and strength as a whole, and as such enable them.....»»
Researchers capture never-before-seen view of gene transcription
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription bubble, so that one.....»»
Researchers report new solid contact, ion-selective electrodes
A research team led by Prof. Huang Xingjiu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences constructed a highly stable solid contact calcium ion-selective electrode. They used synchrotron radiation technique to reveal.....»»
Apple versus donut: How the shape of a tokamak impacts the limits of the edge of the plasma
Harnessing energy from plasma requires a precise understanding of its behavior during fusion to keep it hot, dense and stable. A new theoretical model about a plasma's edge, which can become unstable and bulge, brings the prospect of commercial fusio.....»»
Bacterial model helps reveal how our bodies prevent population explosions—and cancer
For the size of any population to remain stable over time, its birth and death rates must be balanced. If the birthrate is too high, there could be a population explosion; if it is too low, the population will shrink. This kind of balance exists, for.....»»

"Dusty" archives inspire new story about 1886 Charleston earthquake
Late on August 31, 1886, while many people were asleep, a large quake rocked Charleston, South Carolina, and the surrounding region, toppling buildings, buckling railroad tracks, and causing sand to "boil" or bubble from liquefaction. By the time the.....»»
A review of the applications of mercury stable isotopes for tracing volcanism in geologic events
Mercury is a toxic heavy metal that can exist stably as a gas, with high volatility and global distribution in the atmosphere. Volcanoes represent a primary natural source of Hg in the atmosphere, with significant effects on Hg cycles on both global.....»»
What’s New in Android 15 Beta 2: The Fun Stuff!
Since we’re in Android 15 Beta 2, it’s probably safe for you to go ahead and flash this to your Pixel phone, assuming you are OK with the small list of bugs that Google shared. Google certainly thinks this build is stable enough, plus it showcase.....»»
Research: Technology is changing how companies do business
In the fast-paced world of modern business, technology plays a crucial role in shaping how companies operate. One area where this impact is particularly significant is in the organization of production chains—specifically the way goods are made and.....»»
More stable new-vehicle production means higher Q1 sales for suppliers
More stable new-vehicle assembly meant higher sales numbers in the first quarter for many North American suppliers, another welcome sign for parts makers hoping for more consistent production schedules form automakers......»»
Study reveals new mechanism to explain how continents stabilized
Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism proposed by Penn State scientists may explain ho.....»»

Remote Lake Superior island wolf numbers are stable but moose population declining, researchers say
Researchers forced to cut short an annual survey of wildlife on a remote Lake Superior island this winter due to unusually warm weather announced Tuesday that they managed to gather data that shows the wolf population is stable......»»
New "cold war" grows ever warmer as the prospect of a nuclear arms race hots up
Champagne corks popped on December 3, 1989 as Soviet leader Mikhail Gorbachev and US president George H.W. Bush met on the cruise ship, Maxim Gorky, off the coast of Malta to declare the end of the cold war......»»
Mantle heat may have boosted Earth"s crust 3 billion years ago
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare......»»
Enhanced CRISPR method enables stable insertion of large genes into the DNA of higher plants
Scientists at the Leibniz Institute of Plant Biochemistry (IPB) have succeeded for the first time in stably and precisely inserting large gene segments into the DNA of higher plants very efficiently. To do this, they optimized the gene-editing method.....»»
Researchers reveal complex response of microbial communities to wastewater fluctuations
Microbial communities in constructed wetland (CW) sediments are often disturbed by wastewater. It is necessary for the microbial community to maintain a relatively stable composition or biomass in order to continue to remove pollutants from wastewate.....»»
