New artificial neural network model bests MaxEnt in inverse problem example

NCCR MARVEL researchers at EPFL's Chair of Computational Condensed Matter Physics (C3MP) and colleagues have developed an artificial neural network (ANN) model that may serve as a basis for solving inverse problems. Their approach reaches the same level of accuracy as the now commonly used maximum entropy (MaxEnt) method for low-noise data, performs significantly better than this standard technique when the noise strength increases, and features a reduction in computational cost by orders of mag...

3D Printers Are Finally Starting to Work More Like Star Trek's Replicators

Transporters? Spaceships that can travel at the speed of light? Star Trek introduced us to many fantastical technologies that have us looking forward to the 23rd century. But we might not have to wait that long for all the tech Captain Kirk had to play with, as 3D printing has taken another big step toward making…Read more...

Researchers find a way to 3D print whole objects in seconds

When you think of 3D printing, you probably imagine a structure being created layer by layer, from the bottom up. Now, researchers from Switzerland's Ecole polytechnique fédérale de Lausanne (EPFL) say they have developed a completely new way of creating 3D objects that offer remarkable resolution "in record time."

A novel formulation to explain heat propagation

Researchers at EPFL and MARVEL have developed a novel formulation that describes how heat spreads within crystalline materials. This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent.

Personalized cancer vaccines

The only therapeutic cancer vaccine available on the market has so far showed very limited efficacy in clinical trials. EPFL researchers are currently working on an alternative. They have developed a platform that allows a cancer vaccine to be delivered to a precise location and stimulate the immune system in a safe way -- thereby overcoming one of the two obstacles to creating an effective vaccine.

Breathing may change your mind about free will

Is free will just an illusion? For decades, a signal from the brain called the 'readiness potential' has been interpreted to mean that free will may be an illusion. Backed by signals from the brain and lungs, EPFL scientists have discovered that the readiness potential is in fact coupled to breathing and that acts of free will happen as you exhale -- providing an unexpected perspective on free will.

Capturing CO2 from trucks and reducing their emissions by 90%

Researchers at EPFL have patented a new concept that could cut trucks' CO2 emissions by almost 90%. It involves capturing CO2 within the exhaust system, converting it into a liquid and storing it on the vehicle. The liquid CO2 would then be delivered to a service station and where it will be turned back into fuel using renewable energy.

This tiny, soft robo-bug scoots with smarts and survives swats

Nature is a good source of inspiration for roboticists, but it’s rare that nature’s elegance and genius can be replicated in any real way. Still, we’re getting closer. This tiny insect-like robot is made of soft materials and weighs less than a gram, yet can move quickly and with some intelligence — and is robust enough to survive a pounding from a fly swatter. For the most part, tiny robots like this are compromises. For instance, they can move quickly, but only with external power. Or they can...

A soft robotic insect that survives being flattened by a fly swatter

Researchers at EPFL have developed an ultra-light robotic insect that uses its soft artificial muscles to move at 3 cm per second across different types of terrain. It can be folded or crushed and yet continue to move.

When grown right, palm oil can be sustainable

Turning an abandoned pasture into a palm tree plantation can be carbon neutral, according to a new study by EPFL and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). These findings, based on measurements of 56-year-old palm tree plantations in Colombia, suggest we may be able to find sustainable alternatives to deforestation for the production of palm oil -- a practice currently under fire by environmentalists.

EPFL researchers crack an enduring physics enigma

Researchers from EPFL have found the mechanism that lies behind a mysterious physics phenomenon in fluid mechanics: the fact that turbulence in fluids spontaneously self-organizes into parallel patterns of oblique turbulent bands -- an example of order emerging spontaneously from chaos. In so doing, they solved a problem that had stumped generations of physicists.

Producing electricity at estuaries using light and osmosis

Researchers at EPFL are working on a technology to exploit osmotic energy -- a source of power that's naturally available at estuaries, where fresh water comes into contact with seawater. In a laboratory experiment, the team reproduced the real-world conditions that occur where rivers meet the sea (pH and salt concentration) and showed that, by shining light on a system comprising salt, water and a membrane three atoms thick, it was possible to optimize electricity production.

Harnessing photonics for at-home disease detection

With nothing more than a photonic chip and an ordinary camera, EPFL researchers have managed to count biomolecules one by one in a small sample and determine their position. Their tiny device -- a marriage of optics and smart image analysis -- is even able to detect a graphene sheet only a single atom thick. This type of sensor could one day play a key role in personalized medicine.

Prototype prosthesis proffers proper proprioceptive properties

Researchers have created a prosthetic hand that offers its users the ability to feel where it is and how the fingers are positioned — a sense known as proprioception. The headline may be in jest, but the advance is real and may help amputees more effectively and naturally use their prostheses. Prosthesis rejection is a real problem for amputees, and many choose to simply live without these devices, electronic or mechanical, since they can complicate as much as they simplify. Part of that is the ...
