- Cause of high cadmium content in cocoa from Latin America
A few years ago, the press picked up on worrying reports by German scientists that dark chocolate can sometimes contain significant amounts of cadmium, a poisonous heavy metal. Cocoa beans from Lat... - New microscopy technique to measure the forces exerted by biological cells when they grow
An interdisciplinary team of scientists from ETH Zurich has developed a new microscopy technique that allows researchers to measure in great detail the forces exerted by biological cells when they ... - The delicate balancing act of research funding
Many people see privately funded research as a threat to academic independence, but this is an incomplete view. Experts with close connections to politics and business are a logical consequence of ... - A patent for oxidised fat
It is a hotly debated, highly researched subject that has taken on the semblance of a religious war: what are good and what are bad fats? But research from ETH Professor Manfred Kopf's group publis... - The deuteron is smaller than previously thought
The deuteron - one of the simplest atomic nuclei, consisting of just one proton and one neutron - is considerably smaller than previously thought. This finding was arrived at by an international re... - Magnetically aligned graphite electrodes for high rate performance Li-ion batteries
Materials researchers at the Swiss Paul Scherrer Institute PSI in Villigen and the ETH Zurich have developed a very simple and cost-effective procedure for significantly enhancing the performance o... - New method to fabricate programmable colloidal molecules
Scientists at ETH Zurich and IBM Research Zurich have developed a new technique that enables for the first time the manufacture of complexly structured tiny objects joining together microspheres. T... - Direct proof of stable ultra-long 1D carbon chains as a route to carbyne
Elemental carbon appears in many different forms, including diamond and graphite. Their unique structural, electrical and optical properties have a broad range of potential applications in composit... - Highly efficient heavy metal ions filter by using whey and activated charcoal
ETH researchers have developed a new water filtration system that is superior to existing systems in many respects: it is extremely efficient at removing various toxic heavy metal ions and radioact... - How cells detect scents
Cells have an infallible sense of smell that tells them which direction to grow in to move closer to the source of a scent. ETH researchers have now learned how this sense of smell works. A freq...
- Discovery of a new particle
Studying peculiar properties of a long known metallic material researchers have chanced upon a new particle. It is related to the so-called Weyl fermions that the mathematician Hermann Weyl predict... - New type of foam made of real gold
A nugget of real 20 carats gold, so light that it does not sink in a cappuccino, floating instead on the milk foam - what sounds unbelievable has actually been accomplished by researchers from ETH ... - Electrochemistry to satisfy mass demand: the pyrite battery
High-performance lithium ion batteries face a major problem: Lithium will eventually start to run out. Researchers from Empa and ETH Zurich have now discovered an alternative: the "fool's gold batt... - Real-time analysis of metabolic products
Biologists at ETH Zurich have developed a method that, for the first time, makes it possible to measure concentration changes of several hundred metabolic products simultaneously and almost in real... - Laser-optic measuring techniques to optimize diesel cat
The scandal surrounding VW has thrust nitric oxide (NOx) emissions from diesel vehicles into the limelight. Owing to the different engine technologies, these have always been higher than in gasolin... - Chemistry for the methanol economy
Unstable crude oil prices and limited oil resources have made the production of petrochemicals from methanol increasingly popular - above all in China. Scientists at ETH Zurich have now deciphered ... - Extremely strong and heat-resistant
ETH researchers have produced a thin film and extremely fine pillars from a new class of alloys made of multiple finely distributed elements. The material is resistant to extreme pressures and temp... - Making it easier to analyse proteins
Less time, fewer errors and simpler to perform. That is what is promised by this new approach to analysing proteins in the lab. Tina Hovestadt received a Pioneer Fellowship from ETH Zurich for this... - Fluid analysis using ultrasonic waves
Just as the size of transistors continues to decrease, laboratories are also expected to shrink until they eventually fit on a chip. ETH Zurich researchers have developed a system of using sound wa... - Chameleon proteins make individual cells visible
Researchers at ETH Zurich's Department of Biosystems Science and Engineering in Basel have developed a new microscopy technique that enables for the first time to selectively visualize individual c... - Higher doses of vitamin E can reduce the stress on immune cells
You're up in the mountains, the snow is blindingly white, and the sun is blazing down from the sky: ideal skiing conditions - but any skiers carrying the herpes virus might also have to reckon with... - Successful recording of current in membrane channels of contracting cardiac cells
For the first time, scientists have succeeded in recording the current in membrane channels of contracting cardiac cells. To do this, the scientists combined an atomic force microscope with a widel... - Some of UV radiation absorbing chemicals in sunscreens considered to be harmful to health
Researchers at ETH Zurich asked consumers in German-speaking Switzerland how often they used sunscreens and other personal care products. The collected data make for interesting reading: part of th... - Glass for battery electrodes
Today's lithium-ion batteries are good, but not good enough if our future energy system is to rely on electrical power. Chemists and materials scientists at ETH Zurich have developed a type of glas...
- Eco-friendly process to make large amounts of lactic acid from glycerol
Polylactic acid is a degradable plastic used mostly for packaging. To meet the rising demand, ETH researchers have developed an eco-friendly process to make large amounts of lactic acid from glycer...
