Ecole Polytechnique Fédérale de Lausanne Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties. In an atom, magnetism arises from the spin and orbital momentum of its electrons. 'Magnetic anisotropy' describes how an atom's magnetic properties depend on the orientation of the electrons' orbits relative to the structure of a material. It also provides directionality and...

Brain Simulation, Big Data, And A New Computing Paradigm
2014-02-17 04:37:28

redOrbit Staff & Wire Reports - Your Universe Online Experts from the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are combining experimental data with the core principles of brain organization in order to create a detailed computer model which will allow them to conduct supercomputer-based simulations of the brain’s inner workings. “Brain simulation allows measurements and manipulations impossible in the lab, opening the road to a new kind of in silico...

Amputee Feels Sensory Rich Information In Real-time With Bionic Hand
2014-02-06 10:59:41

[ Watch The Video: Amputee Feels in Real-Time with Bionic Hand ] Hillary Sanctuary - Ecole Polytechnique Fédérale de Lausanne Dennis Aabo Sorensen is the first amputee in the world to feel sensory rich information -- in real-­time -- with a prosthetic hand wired to nerves in his upper arm; Sorensen could grasp objects intuitively and identify what he was touching while blindfolded. Nine years after an accident caused the loss of his left hand, Dennis Aabo Sørensen from Denmark...

Scientists Identify Harmful Elements Of Persisting Oil After Deepwater Horizon
2014-01-23 09:08:29

Ecole Polytechnique Fédérale de Lausanne On 20 April 2010, a floating oil rig in the Gulf of Mexico called Deepwater Horizon suddenly exploded, leading to the largest accidental marine oil disaster in the world. Collaborating scientists at EPFL in Switzerland and the Woods Hole Oceanographic Institution (WHOI) in the United States have analyzed the composition of eight oil-soaked sand patties that were collected along the Gulf shores from April until November in 2011. They determined and...

Researchers Find Uranium In A Natural Wetland More Mobile Than Previously Assumed
2013-12-18 09:06:00

Ecole Polytechnique Fédérale de Lausanne Because they are known to mop up pollutants, artificial wetlands are considered to be an efficient strategy to contain waterborne uranium. But studying a natural wetland near a former uranium-mining site in the French region of Limousin, researchers have found that under certain circumstances, uranium can be partly remobilized into the surrounding water. In a recent publication in Nature Communications, they show how it becomes mobile again by...

Ten Times More Throughput On Optic Fibers
2013-12-04 12:56:47

Ecole Polytechnique Fédérale de Lausanne EPFL scientists have shown how to achieve a dramatic increase in the capacity of optical fibers; Their simple, innovative solution reduces the amount of space required between the pulses of light that transport data Optical fibers carry data in the form of pulses of light over distances of thousands of miles at amazing speeds. They are one of the glories of modern telecommunications technology. However, their capacity is limited, because the...

Researchers Improve Nanopore-based Technology For Detecting DNA Molecules
2013-11-18 08:34:01

Ecole Polytechnique Fédérale de Lausanne If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model that EPFL researchers have used for creating a "DNA reader" that is able to detect the passage of individual DNA molecules through a tiny hole: a nanopore with integrated graphene transistor. The DNA molecules are diluted in a solution...

DNA Brings Life To Materials
2013-06-13 14:54:30

Ecole Polytechnique Fédérale de Lausanne A colloid is a substance spread out evenly inside another substance. Everyday examples include milk, styrofoam, hair sprays, paints, shaving foam, gels and even dust, mud and fog. One of the most interesting properties of colloids is their ability to self-assemble — to aggregate spontaneously into well-defined structures, driven by nothing but local interactions between the colloid's particles. Self-assembly has been...

Blowing Glass At A Nano Scale
2013-03-25 11:13:39

Ecole Polytechnique Fédérale de Lausanne EPFL researchers are using the electrical properties of a scanning electron microscope to change the size of glass capillary tubes -- Their method has already been patented as it could pave the way to many novel applications Have you ever thrown into the fire - even if you shouldn't have - an empty packet of crisps? The outcome is striking: the plastic shrivels and bends into itself, until it turns into a small crumpled...

Looking Into Living Cells Without Using Dyes Or Fluophore
2013-02-09 09:46:22

Ecole Polytechnique Fédérale de Lausanne 2 young EPFL scientists have developed a device that can create 3-D images of living cells and track their reaction to various stimuli without the use of contrast dyes or fluorophores In the world of microscopy, this advance is almost comparable to the leap from photography to live television. Two young EPFL researchers, Yann Cotte and Fatih Toy, have designed a device that combines holographic microscopy and...

Word of the Day
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
