Transposons are foreign DNA elements capable of random insertion into the genome, an event that can be very dangerous for a cell. Their activity must be silenced to maintain genomic integrity, which is primarily achieved by H3K9me3-mediated repression. Researchers from the Gasser group identified two parallel pathways that are essential for H3K9me3- mediated transcriptional repression and thus for protecting the genome from toxic transposon activation.

ETH Zurich researchers conducted an experiment to investigate the initial steps in the formation of aerosols. Their findings are now aiding efforts to better understand and model that process - for example, the formation of clouds in the atmosphere.

Scientists have carried out the first comprehensive study of how genes in the liver perform their metabolic functions in both space and time of day. Monitoring almost 5000 genes at the level of the individual cell across a 24-hour period, the researchers have modelled how the circadian clock and liver functions crosstalk throughout the day in sync with the feeding-fasting cycle.

They emit must be systematically stored underground. This is the most economical of various approaches that ETH researchers have compared in detail. It is politically agreed and necessary for climate protection reasons that our entire economy becomes climate-neutral in the coming decades - and that applies to air travel, too.

In the future: processing and memory on a single chip
Researchers have shown that a magnetically polarised current can be manipulated by electric fields. This important discovery opens up the prospect of simultaneously processing and storing data on electrons held in the molecular structure of computer chips - combining computer memory and processing power on the same chip.

Antimatter: A step forward
Antimatter: A step forward
The ASACUSA experiment at CERN has taken an important step forward in developing an innovative technique for studying antimatter. Using a novel particle trap, called a CUSP trap, the experiment has succeeded in producing significant numbers of antihydrogen atoms in flight. Antimatter - or the lack of it - remains one of the biggest mysteries of science.

Antimatter atoms produced and trapped at CERN
Antimatter atoms produced and trapped at CERN
The ALPHA experiment at CERN has taken an important step forward in developing techniques to understand one of the Universe's open questions: is there a difference between matter and antimatter? A study shows that it has successfully produced and trapped atoms of antihydrogen. This development opens the path to new ways of making detailed measurements of antihydrogen, which will in turn allow scientists to compare matter and antimatter.

Circuitry of fear identified
Neurobiologists have identified, for the first time, clearly defined neural circuits responsible for the processing of fear states. These findings could ultimately help people suffering from post-traumatic stress disorder or anxiety disorders. Fear arises in the almond-shaped brain structure known as the amygdala.

Graphene: a promising material
Graphene: a promising material
Graphene is a promising material for tomorrow's nanoelectronics devices, as reported myScience.ch earlier . Precise and upscaleable methods to fabricate graphene and derived materials with desired electronic properties are however still searched after. To overcome the current limitations, researchers have fabricated graphene-like materials using a surface chemical route and clarified in detail the corresponding reaction pathway.

The LHC enters a new phase
Proton running for 2010 in the LHC at CERN came to a successful conclusion. Since the end of March 2010, when the first collisions occurred at a total energy of 7 TeV, the machine and experiment teams have achieved all of their objectives for the first year of proton physics at this record energy and new ground has been explored.

Protons - smaller than we thought
Protons - smaller than we thought
The proton - one of the smallest building blocks of all matter - is even smaller than previously assumed. As a consequence of this discovery, a correction will have to be made to either the quantum theory of how light and matter interact or to the value of the Rydberg Constant - i.e. an important change is needed to either the most precise theory in physics or the most precisely determined physical constant.
