A lifelong fascination with planets

Watching Star Trek as a child first inspired Judit Szulágyi’s fascination with planets and galaxies. Today Forbes ranks the astrophysicist among Europe’s 30 most influential scientists under the age of 30. Watch as she explains how she uses computer simulations to research the birth of giant planets – and how she decided on this career path in the first place. Read more

Sunbathing meteoroids

When a meteoroid travels in space, solar radiation leaves distinctive imprints on its outer layer. Together with colleagues, ETH researcher Antoine Roth has developed novel analytical techniques to detect these imprints, allowing the team to reconstruct meteorites’ space journeys. Read more

Earth is bombarded at random

Asteroids don’t hit our planet at regular intervals, as was previously thought. Earth scientists from ETH Zurich and Lund University in Sweden have reached this conclusion after analysing impact craters formed in the last 500 million years, concentrating on precisely dated events. Read more

How planets like Jupiter form

Young giant planets are born from gas and dust. Researchers of ETH Zürich and the Universities of Zürich and Bern simulated different scenarios relying on the computing power of the Swiss National Supercomputing Centre (CSCS) to find out how they exactly form and evolve. Read more

Galaxies used to play by different rules

ETH researchers studying how stars are formed in distant galaxies have made an unexpected discovery: a correlation that exists today between the proportion of heavy chemical elements in a galaxy and the rate at which new stars are formed in this galaxy did not apply 10 billion years ago. This observation helps scientists understand how galaxies with their stars and planets were formed over billions of years. Read more

A precocious black hole

Black holes can be found at the centres of most galaxies. Most have little mass compared with their host galaxy. ETH researchers, however, have discovered a particularly massive black hole, which clearly grew so quickly that the host galaxy was not able to keep pace. This calls into question previous thinking on the co-evolution of galaxies and their central black holes. Read more

Observing the birth of a planet

Astronomers at ETH Zurich have confirmed the existence of a young giant gas planet still embedded in the midst of the disk of gas and dust surrounding its parent star. For the first time, scientists are able to directly study the formation of a planet at a very early stage. Read more

A new and game-changing magnetoresistance

More than 150 years ago, William Thomson, later Lord Kelvin, discovered the magnetoresistive effect. Today, this finding enables sensors to measure the rotational speed of a car wheel, and is also used in compass navigation and robot control systems. ETH material scientists have now found a new kind of magnetoresistance that promises further insight into basic research and could one day be used for practical applications. Read more

“I see myself as a discoverer”

Professor Ursula Keller’s area of expertise is ultrashort laser pulses. Together with her group at ETH, she is currently developing new metrology techniques and novel semiconductor lasers that might well find application in every household. Ursula Keller will be in California on 13 May 2015 to receive the renowned OSA Charles H. Townes Award in recognition of her achievements. Read more

An unlikely attraction

Like charges normally repel each other. That’s not the case at the interface between air and water. This is where ETH researchers observed an unusual phenomenon with nanoparticles, and found an explanation. Read more

Catching qubits in a trap

Jonathan Home’s laboratory has a room full of equipment that traps tiny ions and places them in special quantum states – perhaps the first step towards building a quantum computer. Read more

A quantum channel made of light

In experiments using ultracold atoms and laser light, ETH researchers have measured a stepwise change in conductivity as the atoms pass through tiny structures. This is the first time that this quantum effect has been observed for electrically neutral particles. Read more

Exotic states of light and matter

With a combination of solid-state physics and quantum optics, ETH researchers observe new multiparticle states that so far defied a complete theoretical description. The experiments might be the first step towards developing quantum computers based on photons. Read more

Solar explosions inside a computer

Strong solar flares can bring down communications and power grids on Earth. By demonstrating how these gigantic eruptions are caused, ETH physicists are laying the foundations for future predictions. Read more

When a doughnut becomes an apple

In experiments using the wonder material graphene, ETH researchers have been able to demonstrate a phenomenon predicted by a Russian physicist more than 50 years ago. They analysed a layer structure that experts believe may hold unimagined promise. Read more

“The ball is in D-Wave’s court”

Google and American defence company Lockheed Martin paid more than USD 10 million for a quantum computer, although its exact capabilities are unknown. A team headed by ETH professor Matthias Troyer examined the question of how to properly test such devices, creating quite a stir in the process. Read more

Protecting olive oil from counterfeiters

Who guarantees that expensive olive oil isn't counterfeit or adulterated? An invisible label, developed by ETH researchers, could perform this task. The tag consists of tiny magnetic DNA particles encapsulated in a silica casing and mixed with the oil. Read more

The ATM strikes back

Hot foam may soon send criminals running if they damage ATM. ETH researchers have developed a special film that triggers an intense reaction when destroyed. The idea originates from a beetle that uses a gas explosion to fend off attackers. Read more

Preventing natural gas crises

Europe can withstand a significant shortage in its natural gas supply provided it has a fair distribution strategy. ETH researchers have developed a model demonstrating how best to mitigate deficits in the pipeline network. Read more
