Previously Unknown Extinction of Marine Megafauna Discovered
Previously Unknown Extinction of Marine Megafauna Discovered
The disappearance of a large part of the terrestrial megafauna such as saber-toothed cat and the mammoth during the ice age is well known. Now, researchers at the University of Zurich and the Naturkunde Museum in Berlin have shown that a similar extinction event had taken place earlier, in the oceans.

Discovery of a new mechanism for bacterial division
Discovery of a new mechanism for bacterial division
EPFL scientists show how some pathogenic bacteria†- such as the mycobacteria that cause tuberculosis†-†use a previously unknown mechanism to coordinate their division. The discovery could help develop new ways to fight them.† Most rod-shaped bacteria divide by splitting into two around the middle after their DNA has replicated safely and segregated to opposite ends of the cell.

A 100-year-old physics problem has been solved at EPFL
A 100-year-old physics problem has been solved at EPFL
EPFL researchers have found a way around what was considered a fundamental limitation of physics for over 100 years. They were able to conceive resonant systems that can store electromagnetic waves over a long period of time while maintaining a broad bandwidth. At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought.

Injector 2: a pre-accelerator for protons
Injector 2: a pre-accelerator for protons
As fundamental building blocks of matter, protons are a part of all things that surround us. At the Paul Scherrer Institute PSI, however, they step out of their usual role and are deployed to generate other particles, namely neutrons and muons, which are subsequently used to study materials.

Effects of ozone depletion felt in the Tropics
Effects of ozone depletion felt in the Tropics
Media releases, information for representatives of the media Media Relations (E) The hole in the ozone layer above Antarctica has more far-reaching consequences than previously assumed. A study by Bernese climate researchers has now shown that it even affects precipitation in the tropical regions of the Pacific, 10,000†kilometres away.

The largest virtual Universe ever simulated
Over a period of three years, a group of astrophysicists from the University of Zurich has developed and optimised a revolutionary code to describe with unprecedented accuracy the dynamics of dark matter and the formation of large-scale structures in the Universe.

Alpine streams produce more CO2 after a warm winter
Alpine streams produce more CO2 after a warm winter
An EPFL study has for the first time measured the impact of climate change on alpine streams, and the results are quite worrying: after a low-snow winter, these streams release more carbon dioxide than they absorb. Numerous researchers are looking at the impact of climate change on the Alps. And one of the most obvious effects is the low snowfall observed in recent years.

Relation between comets and earth‚? s atmosphere uncovered
Media releases, information for representatives of the media Media Relations (E) The difficult yet successful measurement of several isotopes of the noble gas xenon on comet 67P/Churyumov-Gerasimenko using the Bernese instrument ROSINA on the Rosetta probe shows that materials arrived on Earth due to comet impacts.

Big help for small children
Cancer affects only very few children. Nonetheless, malignant tumours can develop above all in the muscles, bones and nerve tissue of the very young.

In vitro testing could be improved
In vitro testing could be improved
EPFL researchers propose a new approach of performing in vitro tests on nanoparticles that could enhance a correlation to in vivo results. This involves reproducing in the lab the dynamic and fluidic variations that these particles experience in the human body. Before new nanoparticles or other nanomedicines can be injected into the human body, a whole series of tests must be conducted in the laboratory, then in living cells, and in the end on humans.

Dogs Help in Breast Carcinoma Research
Dogs Help in Breast Carcinoma Research
Cancer is one of the most frequent diseases not only in people, but in pets as well. Like people, dogs can also suffer from cancer of the mammary glands (mammary tumors). Dog mammary tumors are very similar to breast carcinoma in humans, and much more so than those of rats or mice, for example. For this reason, research on canine mammary tumors is important for human medicine as well.
