Ultrafast imaging of terahertz electric waveforms using quantum dots
Microscopic electric fields govern a remarkable variety of phenomena in condensed matter and their ultrafast evolutions drive plasmonics, phononics and highspeed nanoelectronics. Access to high-frequency electric waveforms is of crucial importance to.....»»
Computer model of blood enzyme may lead to new drugs for cardiovascular disease
Membrane-associated proteins play a vital role in a variety of cellular processes, yet little is known about the membrane-association mechanism. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is one such protein with an important role in cardiovas.....»»
Liquid-metal experiment provides insight into the heating mechanism of the sun"s corona
Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A "hot" trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and c.....»»
Dorsal-ventral patterning mechanism provides insights into unique developmental mode and evolution of spiralians
The formation of the dorsal-ventral (DV) axis is one of the most important events during the early development of bilaterian animals. It is widely accepted that a conserved molecular logic (BMP2/4 and Chordin) regulates tissue differentiation along t.....»»
Watch this pest controller use a drone to vacuum up a wasp nest
A company in Japan has developed a drone with a vacuum mechanism that enables a pest controller to remove a wasp nest while standing a safe distance away......»»
Researchers identify mechanism that explains how tissues form complex shapes that enable organ function
From the smooth tubes of our arteries and veins to the textured pockets of our internal organs, our bodies are made of tissues arranged in complex shapes that aid in performing specific functions......»»
Gallic acid and stretching decrease osteoarthritis markers in cartilage cells
Researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination no.....»»
New study reveals how epithelial cells in the body naturally eliminate "precancerous" ones
Normal epithelial cells show the ability to push out precancerous ones present in the epithelium, by means of 'cell competition.' But the exact molecular mechanism of this recognition by normal epithelial cells was unknown. Now, researchers have unra.....»»
Remote areas are not safe havens for biodiversity
An international research team led by Associate Professor Giovanni Strona from the University of Helsinki has identified a general macroecological mechanism that calls for a reconsideration of global conservation strategies......»»
Viruses can hitch a ride on bacteria
The interaction of fungi and bacteria in the transport of viruses in the soil ecosystem has been examined by a UFZ research team in a study recently published in The ISME Journal. The scientists showed a novel mechanism of viral transport by bacteria.....»»
Research reveals features that influence phase separation
Scientists at St. Jude Children's Research Hospital and Washington University in St. Louis are dissecting the fundamental principles of biological phase separation, a process that is a major mechanism governing how cells are organized. The latest fin.....»»
A new concept for high-performance detectors
When the Department of Energy's SLAC National Accelerator Laboratory turned on the world's first hard X-ray free-electron laser in 2009, it marked the beginning of a new era in science—one where researchers could directly observe the ultrafast moti.....»»
A missing genetic switch at the origin of malformations
Embryonic development follows delicate stages: for everything to go well, many genes must coordinate their activity according to a very meticulous scheme and tempo. This precision mechanism sometimes fails, leading to more or less disabling malformat.....»»
Atomic structure of antifungal drug confirms unusual mechanism, opens door to less-toxic derivatives
Advanced molecular imaging technology has now mapped the structure of a drug widely used to treat fungal infections but whose workings have mystified researchers and physicians for nearly 70 years. Researchers now described in atomistic detail the st.....»»
