A step closer to single-atom data storage
A step closer to single-atom data storage
Physicists at EPFL used Scanning Tunneling Microscopy to successfully test the stability of a magnet made up of a single atom. Despite the rise of solid-state drives, magnetic storage devices such as conventional hard drives and magnetic tapes are still very common. But as our data-storage needs are increasing at a rate of almost 15 million gigabytes per day, scientists are turning to alternative storage devices.

Smart Nanoparticles keep immunotherapy focused on cancer
Smart Nanoparticles keep immunotherapy focused on cancer
MIT and EPFL researchers have developed a highly targeted and non-toxic method for battling cancer through immunotherapy. Their nanoparticle gel acts only on immune cells surrounding the tumor, without affecting the rest of the body. Immunotherapy is a highly promising and innovative approach to battling cancer that works by enlisting the body's natural defenses to attack cancer cells.

Fight against viruses: The origin of specific immune cells revealed
Fight against viruses: The origin of specific immune cells revealed
Within the immune system, so called plasmacytoid dendritic cells (pDCs) play a relevant role in the protection against viral infections. However, pDCs have also been associated with auto immune syndromes. In the current , a research team of the University of Basel could finally solve the puzzle about of their origin.

Dust is in the air
Dust is in the air
Current legal limits for fine dust in the air are based on the mass and size of the particles. For health effects, however, not only the amount of dust is decisive, but also its chemical composition. Empa researchers have now compared the noxious potential of particulate matter in Switzerland and in China.

Making opaque materials totally transparent
Making opaque materials totally transparent
EPFL researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves can propagate at a constant amplitude - regardless of what may lie in their path. This method could eventually be used to make it possible to hide objects like submarines.

An unlikely marriage among oxides
An unlikely marriage among oxides
Sebastian Siol is looking for new materials with unusual properties that were so far not accessible in experiments. To do this, he connects partners who don't really fit together: One partner forces the other into a state that would not be possible without the unlikely pairing. Siol also makes sure that the crystal bonds last in everyday life.

Diamond watch components
Diamond watch components
Researchers have developed a new technique for carving materials to create micromechanical systems. In particular, they have created a miniscule watch component out of synthetic single-crystal diamond. Diamond is very hard and elastic, a very good thermal conductor and highly transparent, which makes it ideal for many mechanical and optical applications.

Biological light sensor filmed in action
Film shows one of the fastest processes in biology Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule.

Tracking down the mystery of entangled particles of light
Tracking down the mystery of entangled particles of light
Bernese researchers have taken an important step towards new measurement methods such as quantum spectroscopy. In an experiment, they succeeded in uncovering part of the mystery surrounding the so-called "entangled photons" and gaining fine control on the measured correlations. Quantum technologies hold the promise to go beyond the capabilities of classical present technologies by making use of pure quantum phenomenon, such as "entangled particles".

Silicon-perovskite solar cells achieve record efficiency of 25,2%
Silicon-perovskite solar cells achieve record efficiency of 25,2%
In Neuchâtel (Switzerland), researchers from EPFL and CSEM have combined siliconand perovskite-based solar cells. The resulting efficiency of 25.2% is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30%.

A nanotech sensor turns molecular fingerprints into bar codes
A new system developed at EPFL can detect and analyze molecules with very high precision and without needing bulky equipment. It opens the door to large-scale, image-based detection of materials aided by artificial intelligence. Infrared spectroscopy is the benchmark method for detecting and analyzing organic compounds.

Direct Coupling of the Higgs Boson to the Top Quark Observed
Direct Coupling of the Higgs Boson to the Top Quark Observed
On 4 July 2012, two of the experiments at the CERN's Large Hadron Collider (LHC), ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact Muon Solenoid), reported independently the discovery of the Higgs boson. The discovery confirmed the existence of the last missing elementary particle of the Standard Model, half a century after the Higgs boson was predicted theoretically.

Hollywood in the Würenlingen woods
With the X-ray laser SwissFEL, researchers at PSI want to produce movies of biomolecules in action. This can reveal how our eyes function or how new drugs work. Luc Patthey stands next to a complicated arrangement of optical lenses, measuring instruments, countless cables, and a thin steel pipe. We're in Hollywood here.

Deciphering the language of cells using observation chambers
EPFL researchers have developed an innovative label-free method for studying the behavior of single cells continuously and in real time. By placing a cell in a small chamber containing nanosensors and observing it over many hours, it is possible to identify the cell's unique personality and understand how it communicates.

So that Ronaldo and Co. can «conjure»
The official ball for the 2018 FIFA World Cup in Russia has received Empa's «OK» after numerous tests. Some goalkeepers may be critical of its flight characteristics, but the reason for their criticism may lie somewhere else - the rather unconventional appearance of the new ball. Football lives on emotions.

Observing cellular activity, one molecule at a time
Using a new mode of atomic force microscopy, researchers at EPFL have found a way to see and measure protein assembly in real time and with unprecedented detail. Proteins and molecules assemble and disassemble naturally as part of many essential biological processes. It is very difficult to observe these mechanisms, which are often complex and take place at the nanometer scale, far smaller than the normal visible range.
