LHCb experiment observes new matter-antimatter difference
LHCb experiment observes new matter-antimatter difference
The LHCb collaboration at CERN observed the first matter-antimatter asymmetry in the decays of the particle known as the B0 s . It is only the fourth sub-atomic particle known to exhibit such behaviour. Matter and antimatter are thought to have existed in equal amounts at the beginning of the universe , but today the universe appears to be composed essentially of matter.

A Magic Formula to Predict Fracture in Steel
A Magic Formula to Predict Fracture in Steel
Researchers have elucidated a century-old mystery: how hydrogen destroys steels. A new mathematical model predicts this failure in the presence of the destructive atoms. A veritable gangrene for steels and other structural metals, hydrogen is one of the most important causes of ruptures in industrial parts, such as pipelines.

Using rust and water to store solar energy as hydrogen
Using rust and water to store solar energy as hydrogen
Scientists are producing hydrogen from sunlight, water and rust. They're paving the way for an economic and ecological solution for storing renewable energy. How can solar energy be stored so that it can be available any time, day or night, when the sun shining or not? EPFL scientists are developing a technology that can transform light energy into a clean fuel that has a neutral carbon footprint: hydrogen.

A Revolutionary Type of Gel
A Revolutionary Type of Gel
Controlling and modifying at will the transparency, electrical properties, and stiffness of a gel - such are the promises of a new discovery by physicists. This marks an important step for materials used in healthcare, high-tech, and the cosmetics industry. At the mention of gel, we immediately imagine extravagant hairstyles.

A new method for early cancer detection
A new method for early cancer detection
It may soon be possible to test a person for cancer with just a drop of their blood and a small machine. Scientists have developed a device for detecting the HSP70 protein, which is over-expressed in patients with many types of cancer. The objective: to make a diagnosis extremely early in the disease process, thereby improving outcomes for patients.

New Technique to Diagnose Hearing Loss
New Technique to Diagnose Hearing Loss
Researchers have developed an imaging technique that can provide in situ observations of the internal ear, an area which has until now been inaccessible. This groundbreaking work may finally make it possible to understand the mechanisms underlying hearing loss. What actually causes hearing loss in humans? And what are the best therapeutic approaches to this problem? Modern medicine hasn't yet been able to provide doctors with the right answers in many cases, because there has been no way to observe the tissue of the inner ear, without destroying it.

Nano-velcro clasps heavy metal molecules in its grips
Nano-velcro clasps heavy metal molecules in its grips
Researchers develop nano-strips for inexpensive testing of mercury levels in our lakes and oceans with unprecedented sensitivity Mercury, when dumped in lakes and rivers, accumulates in fish, and often ends up on our plates. A Swiss-American team of researchers led by Francesco Stellacci at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and Bartosz Grzybowski at Northwestern University has devised a simple, inexpensive system based on nanoparticles, a kind of nano-velcro, to detect and trap this toxic pollutant as well as others.

New-generation sensor combines lasers and mechanics
New-generation sensor combines lasers and mechanics
Scientists have developed a rapid, precise opto-mechanical measurement system that can be embedded into a silicon chip. This new technology could revolutionize the domain of sensors and atomic force microscopy. Resonators are used to detect infinitesimal quantities of matter in the atmosphere. Here's how it works: when a microscopic string comes into with a particle or a gas molecule, it vibrates.

CERN experiments observe particle consistent with long-sought Higgs boson
CERN experiments observe particle consistent with long-sought Higgs boson
Geneva, 4 July 2012. At a seminar held at CERN today as a curtain raiser to the year's major particle physics conference, ICHEP2012 in Melbourne, the ATLAS and CMS experiments presented their latest preliminary results in the search for the long sought Higgs particle. Both experiments observe a new particle in the mass region around 125-126 GeV.

Probing the secrets of unmagnetized magnets
Probing the secrets of unmagnetized magnets
Physicists studying magnetic materials have discovered that they have some unexpected properties. Their research could lead to the development of even tinier magnets in the future. Magnets are everywhere; stuck to our fridges, used in electric motors, built into the hard disks on our computers. Scientists have studied them for centuries, but it's only recently that a team from EPFL's Laboratory for Quantum Magnetism has probed the details of their innermost structure.

Lethal weapon used by viruses
Lethal weapon used by viruses
It could be the tiniest armor-piercing weapon in the biological universe: Scientists have measured a one-nanometer needle-like tip that viruses use to attack bacteria. Grouped together under the unassuming name φ92, a family of bacteriophage viruses has perfected its specialty: they attack salmonella and coliform bacteria.

How to turn leaves into solar panels
How to turn leaves into solar panels
Photovoltaic panels made from plant material could become a cheap, easy alternative to traditional solar cells. An entirely novel approach to photovoltaics has been developed. By taking the very protein in plants that allows for photosythesis and engineering it to produce electrical current, researcher Andreas Mershin has opened the door for potentially cheap and easy to reproduce solar energy.

Mapping a fixed point
Mapping a fixed point
For fifty years, mathematicians have grappled with the so-called "fixed point" theorem. A team has now found an elegant, one-page solution that opens up new perspectives in physics and economics. Take a map of the world. Now put it down on the ground in Central Park, against a rock on Mount Everest, or on your kitchen table; there will always be a point on the map that sits exactly on the actual physical place it represents.

Successful LHC proton run
Successful LHC proton run
After some 180 days of running and four hundred trillion proton proton collisions, the LHC's 2011 proton run came to an end at 5.15pm yesterday evening. For the second year running, the LHC team has largely surpassed its operational objectives, steadily increasing the rate at which the LHC has delivered data to the experiments.

A guiding light for new directions in energy production
A guiding light for new directions in energy production
Advances in the field could help solve the energy challenge. The science of light and liquids has been intimately entwined since Léon Foucault discovered the speed of light in 1862, when he observed that light travels more slowly in water than in air.

A faster, cheaper method for making transistors and chips
It may soon be possible manufacture the miniscule structures that make up transistors and silicon chips rapidly and inexpensively. EPFL scientists are currently investigating the use of dynamic stencil lithography, a recent but not yet perfected method, for creating nanostructures. Faster, less expensive, and better.

Are neutrinos faster than the speed of light?
Are neutrinos faster than the speed of light?
Researchers measured that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature's cosmic speed limit. This is a result of t he OPERA experiment which observes neutrino beams from CERN 730 km away at a Laboratory near Rome. The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature's cosmic speed limit.

Could the Higgs boson explain the size of the Universe?
The Universe wouldn't be the same without the Higgs boson. This legendary particle plays a role in cosmology and reveals the possible existence of another closely related particle. The race to identify the Higgs boson is on at CERN. This Holy Grail of particle physics would help explain why the majority of elementary particles possess mass.
