Could the Higgs boson explain the size of the Universe?
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.

The apple doesn’t fall far from the tree - or does it?
The apple doesn’t fall far from the tree - or does it?
Research has shown that contrary to what was thought from previous studies, spin-outs don't systematically set up shop near their parent companies. To stay or to leave, what's the best strategy? “I was really surprised, when doing this research, to find that 50% of spin-outs don't necessarily establish themselves near the parent company,” observes Christopher Tucci from EPFL.

Pyramidal dots for future quantum computers
Pyramidal dots for future quantum computers
The enigmatic quantum dot is the basic building block for quantum computers. Physicists have developed a new theory to determine the optical properties of these dots based on the principles of symmetry. Physicists from EPFL have created a pyramidal dot that's just shy of 100 nanometers high, about 200 atoms on a side.

Profiler at the cellular level
Researchers have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction. Yaakov (Kobi) Benenson, from ETH Zurich, has spent a large part of his career developing biological computers that operate in living cells.

An innovative method for measuring nanoparticles
An innovative method for measuring nanoparticles
Precise measurement of the molecular weight, size and density of a nanoparticle in a single procedure is now possible, thanks to an ultracentrifugation method. Although nanoparticles are used in a variety of domains - such as medicine, solar energy and photonics - there is still much about them to be discovered.

Combating fungal diseases
Combating fungal diseases
Scientists have discovered a potential new approach for inhibiting the growth of pathogenic fungi. Ultimately, immunocompromised patients with fungal infections, in particular, could benefit from this work. As temperatures soar and more and more people cool off at outdoor pools, the incidence of so called swimmer's ear - an infection of the ear canal - also rises.

Simulations to protect the Valais
Scientists model sediment deposits carried by the Naviscence River in the Swiss Valais canton. They are simulating possible scenarios for the future of the Zinal ski area, which could be threatened by the river.

Unprecedented insight into cloud formation
Unprecedented insight into cloud formation
The CLOUD experiment has been designed to study the effect of cosmic rays on the formation of atmospheric aerosols - tiny liquid or solid particles suspended in the atmosphere - under controlled laboratory conditions. Atmospheric aerosols are thought to be responsible for a large fraction of the seeds that form cloud droplets.

Scanners reveal a wreck in the Lake Geneva
Scientists have discovered a new wreck on the bottom of the Lake Geneva. Underwater archaeology is benefiting from scanners developed for scientific research. “It's always a memorable moment when you find an unknown shipwreck. It's not on the maps, and after having gone around it, I didn't see any inscription on its hull,” explains Evgeny Chernyaev, who was piloting the submersible.

Holograms Reveal Brain’s Workings,
Like far away galaxies, powerful tools are required to bring the minute inner workings of neurons into focus. A team of scientists report how Digital Holographic Microscopy (DHM) can now be used to observe neuronal activity in real-time and in three dimensions—with up to 50 times greater resolution than ever before.

New method for the diagnosis of cancer
New method for the diagnosis of cancer
Researchers have developed a new breast cancer diagnostic method, and is now carrying out first tests on non-preserved human tissue. This new method should be able to reveal structures that cannot be seen using conventional mammography. Standard procedures only determine the extent to which X-rays are attenuated by various tissue structures.

A closer look at cells
A closer look at cells
Many substances and nutrients are exchanged across the cell membrane. Scientists have developed a method to observe these exchanges, by taking a highly accurate count of the number of proteins found there. Proteins on the cell surface play an essential role in the survival of the cell. They govern the exchanges between the interior and the exterior.

From raindrop to flood
Scientists are starting a new field campaign in the Val Ferret. They're collecting data to study how the environment influences flood rates in mountain valleys. Predicting natural disasters in order to inform and warn populations residing in risk zones is a major challenge today. “Mathematical models exist, but they still don't take into account all the data that are needed to establish reliable predictions, such as the influence of air temperature, the formation of thermal winds or the impact of precipitation,” explains Professor Marc Parlange.

How will Swiss radioactive waste be disposed of?
If Switzerland does indeed abandon nuclear energy within the time-frame announced by the Swiss Confederation, the question of the burial and disposal of the accumulated waste needs to be addressed.
