By applying light, University of Arkansas physicists Peng Chen and Laurent Bellaiche have discovered a surprising mechanism for controlling ferroelectric polarization in a deterministic manner......»»
Ultrafast "camera" captures hidden behavior of potential "neuromorphic" material
Imagine a computer that can think as fast as the human brain while using very little energy. That's the goal of scientists seeking to discover or develop materials that can send and process signals as easily as the brain's neurons and synapses. Ident.....»»
Chronobiologists identify key circadian clock mechanism in cyanobacteria
Researchers have identified a key mechanism involved with the setting of the circadian clock of cyanobacteria—a model organism for study by chronobiologists due to the organism having one of the earliest circadian systems to evolve, and thus shinin.....»»

Research led by Hong Kong University of Science and Technology (HKUST) has revealed a novel mechanism that regulates secretion of sonic hedgehog (Shh), a key signaling molecule that plays an important role in cancer progression in mammals, opening th.....»»
Land snail shell: A recorder of weather scale precipitation events
Extreme weather events can exert profound impacts on society, economy and environment. However, short instrumental data limits our understanding of their mechanism and the evaluation of climate models......»»
AnimeKisa.tv Shuts Down, Says That Pirates Don’t Like to Pay or View Ads
A popular anime piracy site has thrown in the towel after issues with its funding mechanism could not be resolved. AnimeKisa had been receiving up to 20 million visits per month but its users preferred not to view lots of ads. The site switched to a.....»»
Mechanism "splits" electron spins in magnetic material
Holding the right material at the right angle, Cornell researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet—a technique that could eventually lead to the development of more energy-efficient magnetic me.....»»
Gene expression in the nervous system: Researchers discover a mechanism for its targeted stimulation
Genes are the carriers of our genetic information. They are read in our cells and used to produce ribonucleic acids (RNAs). During this process, termed transcription, the enzyme RNA polymerase II has a decisive influence on the exact time at which ge.....»»
Research identifies key connection between gravitational instability in physical gels and granular media
Researchers from Tokyo Metropolitan University have identified key similarities between the behavior of granular materials and melting gels. They found that falling beds of sand share the same destabilization mechanism as melting gelatin as it is hea.....»»
Discovery of aberrant protein that kills bacterial cells could help unravel mechanism of certain antibiotics
Biologists at the U.S. Department of Energy's Brookhaven National Laboratory and their collaborators have discovered an aberrant protein that's deadly to bacteria. In a paper just published in the journal PLOS ONE, the scientists describe how this er.....»»
Researchers reveal activation mechanism of thyrotropin-releasing hormone receptor
Thyroid hormone (TH) plays a multifunctional role in metabolism and development in vertebrates. The synthesis and secretion of TH is determined by the hypothalamus-pituitary-thyroid (HPT) axis. The tripeptide thyrotropin-releasing hormone (TRH, pGlu-.....»»
Ultrafast optical-magnetic memory device
Magnetic random-access memory (MRAM) technology offers substantial potential towards next-generation universal memory architecture. However, state-of-the-art MRAMs are still fundamentally constrained by a sub-nanosecond speed limitation, which has re.....»»
Researchers create exotic magnetic structures with laser light
Research at Lund University in Sweden has found a new way to create nano-sized magnetic particles using ultrafast laser light pulses. The discovery could pave the way for new and more energy-efficient technical components and become useful in the qua.....»»
Haber-Bosch at the atomic scale
Industrial production of NH3 has been performed by the Haber-Bosch process for more than 100 years, in which dissociation of N2 feedstock molecules promoted by alkali atom co-catalyst is thought to be the rate limiting step. The Haber-Bosch synthesis.....»»
Structural and functional studies of adhesion receptors disclose intrinsic activation mechanism of orphan GPCRs
G protein-coupled receptors (GPCRs) play a crucial role in cell signal transduction and comprise the largest drug target protein family. Despite recent breakthroughs in structural and pharmacological studies of these receptors, more than 100 GPCRs re.....»»
Twitter"s board put up a defense mechanism against Elon Musk. Here"s what he could do next
Twitter has indicated that it's not interested in being bought by the world's richest man without a fight. The social network's board made a defensive maneuver that could thwart Elon Musk's takeover bid, but he still has a range of options that sugge.....»»
