New understanding of how shape and form develop in nature. Researchers have developed a new method for generating complex shapes, and have found that the development of form in nature can be driven by the physical properties of materials themselves, in contrast with earlier findings.
The results, reported in the journal Nature, could enable the construction of complex structures from simple components, with potential applications in pharmaceuticals, paints, cosmetics and household products such as shampoo. Team refrigerates liquids with a laser for the first time. New hologram technology created with tiny nanoantennas. Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing.
The metasurface, thousands of V-shaped nanoantennas formed into an ultrathin gold foil, could make possible "planar photonics" devices and optical switches small enough to be integrated into computer chips for information processing, sensing and telecommunications, said Alexander Kildishev, associate research professor of electrical and computer engineering at Purdue University. Laser light shines through the nanoantennas, creating the hologram 10 microns above the metasurface. X-ray microscope reveals 'Solitons,' a special type of magnetic wave. Researchers used a powerful, custom-built X-ray microscope at the Department of Energy's SLAC National Accelerator Laboratory to directly observe the magnetic version of a soliton, a type of wave that can travel without resistance.
Scientists are exploring whether such magnetic waves can be used to carry and store information in a new, more efficient form of computer memory that requires less energy and generates less heat. Magnetic solitons are remarkably stable and hold their shape and strength as they travel across a magnetic material, just as tsunamis maintain their strength and form while traversing the ocean. This offers an advantage over materials used in modern electronics, which require more energy to move data due to resistance, which causes them to heat up. First 'porous liquid' invented: Major breakthrough with the potential for a massive range of new technologies including 'carbon capture' Scientists at Queen's University Belfast have made a major breakthrough by making a porous liquid -- with the potential for a massive range of new technologies including 'carbon capture'.
Researchers in the School of Chemistry and Chemical Engineering at Queen's, along with colleagues at the University of Liverpool and other, international partners, have invented the new liquid and found that it can dissolve unusually large amounts of gas, which are absorbed into the 'holes' in the liquid. The results of their research are published in the journal Nature. Une bactérie alchimiste produit de l'or. Des scientifiques ont découvert une bactérie qui «mange» du métal toxique avant de déféquer de l’or, rapporte ce vendredi le site de Slate.
Alchimiste, la bactérie? Il semblerait. De son doux nom «Cupriavidus metallidurans», elle se nourrit de chlorure d'or, un poison, et après une semaine, elle rejette des pépites d’or 24 carats, soit de l'or à 99,99% pur. Hyper-résistante, cette bactérie prouverait qu’une forme d’alchimie existe dans la nature. Problème pour les alchimistes de tout poil: il faut de l’or pour produire du chlorure d’or, «nourriture» des bactéries. The solution to faster computing? Sing to your data: Sound offers new method of moving data in racetrack memory. Nothing is more frustrating that watching that circle spinning in the centre of your screen, while you wait for your computer to load a programme or access the data you need.
Now a team from the Universities of Sheffield and Leeds may have found the answer to faster computing: sound. The research -- published in Applied Physics Letters -- has shown that certain types of sound waves can move data quickly, using minimal power. Magnetismi. Continuum Mechanics. How to Make a Metamaterial that Expands Under Pressure and Contracts In Tension. Compress a material and it will deform in the direction of the applied force: in other words, it becomes squashed. Annealing (metallurgy) Simulated annealing. The method was independently described by Scott Kirkpatrick, C.
Quantum Biology. 150925142658. A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells, researchers report.
The study offers the first reliable method for tracing viral evolution back to a time when neither viruses nor cells existed in the forms recognized today, the researchers say. The new findings appear in the journal Science Advances. Until now, viruses have been difficult to classify, said University of Illinois crop sciences and Carl R. Woese Institute for Genomic Biology professor Gustavo Caetano-Anollés, who led the new analysis with graduate student Arshan Nasir. Scientists Prove DNA Can Be Reprogrammed by Words and Frequencies. By Grazyna Fosar and Franz Bludorf THE HUMAN DNA IS A BIOLOGICAL INTERNET and superior in many aspects to the artificial one.
Peppered Moth Simulation. Name:______________________________________________ Objective: Simulate changes in moth population due to pollution and predation, and observe how species can change over time.
Introduction: Charles Darwin accumulated a tremendous collection of facts to support the theory of evolution by natural selection. The Secret Life of Plankton. GRAPHENE etc. Surprise link between weird quantum phenomena: Heisenberg uncertainty principle sets limits on Einstein's 'spooky action at a distance' Researchers have uncovered a fundamental link between the two defining properties of quantum physics. The result is being heralded as a dramatic breakthrough in our basic understanding of quantum mechanics and provides new clues to researchers seeking to understand the foundations of quantum theory.
BioPhotons ~ Secrets of the Human Energy Field Revealed! Nitrogen-Fed Bacteria Could Power Our Future. A bacterium that doesn't need its nitrogen preprocessed could breathe new life into environmentally friendly ethanol production, turning mowing the lawn from a chore into an income source. Most ethanol is currently produced from corn or sugar, competing with food for the raw materials while also combating rising prices, among other problems. Biotech Interest in Mini Organs Booms.
