Muscle aging: Stronger for longer
Muscle aging: Stronger for longer
With life expectancy increasing, age-related diseases are also on the rise, including sarcopenia, the loss of muscle mass due to aging. Researchers from the University of Basel's Biozentrum have demonstrated that a well-known drug can delay the progression of age-related muscle weakness. The findings were recently published in -Nature Communications-.

A robot that controls highly flexible tools
A robot that controls highly flexible tools
How do you calculate the coordinated movements of two robot arms so they can accurately guide a highly flexible tool? ETH researchers have integrated all aspects of the optimisation calculations into an algorithm. The hot-wire cutter will be used, among other things, to develop building blocks for a mortar-free structure.

A lack of oxygen in tumors promotes metastasis
A lack of oxygen in tumors promotes metastasis
Metastases are formed by cancer cells that break away from the primary tumor. A research group at the University of Basel has now identified lack of oxygen as the trigger for this process. The results reveal an important relationship between the oxygen supply to tumors and the formation of metastases.

Nationwide decline of threatened plant species in Switzerland
Nationwide decline of threatened plant species in Switzerland
The Swiss Flora is one of the richest and most diverse in Europe. However, more than 700 plant species are considered to be threatened. In a nationwide project over 400 volunteer botanists revisited known populations of all threatened and rare plant species in Switzerland and recorded their presence or absence.

Romantic partners influence each other's goals
Romantic partners influence each other’s goals
Over the long-term, what one partner in a two-person relationship wishes to avoid, so too does the other partner - and what one wants to achieve, so does the other. These effects can be observed regardless of gender, age and length of the relationship, as researchers from the University of Basel report in a study of more than 450 couples.

A tiny instrument to measure the faintest magnetic fields
A tiny instrument to measure the faintest magnetic fields
Physicists at the University of Basel have developed a minuscule instrument able to detect extremely faint magnetic fields. At the heart of the superconducting quantum interference device are two atomically thin layers of graphene, which the researchers combined with boron nitride. Instruments like this one have applications in areas such as medicine, besides being used to research new materials.

Reconfiguring microwave photonic filters without an external device
Reconfiguring microwave photonic filters without an external device
Researchers from EPFL's Photonics Systems Lab have come up with a way of reconfiguring microwave photonic filters without the need for an external device. This paves the way for more compact, environmentally friendly filters that will be more practical and cheaper to use. Potential applications include detection and communications systems.

A difficult year for forests, fields and meadows
A difficult year for forests, fields and meadows
The warm, dry summer of 2018 has left clear traces in various ecosystems. ETH Zurich researchers have found that if the climate continues to warm up, higher altitudes can also expect negative consequences in the future. It was - once again - an unusually hot year: in 2018, large parts of Europe were beset by an extremely hot and dry summer.

Surprise on Mars
Surprise on Mars
NASA's InSight mission provides data from the surface of Mars. Its seismometer, equipped with electronics built at ETH Zurich, not only records marsquakes, but unexpectedly reacts to solar eclipses as well. When the Martian moon, Phobos moves directly in front of the sun, the instrument tips slightly to one side.

A step towards a better understanding of molecular dynamics
A step towards a better understanding of molecular dynamics
Researchers, working at the boundary between classical and quantum physics, have developed a method for quickly spotting molecules with particularly interesting electron properties. Laser technology is giving scientists an ever-closer look into molecular structures, and this sometimes leads to very interesting surprises.

New model explains when the brain becomes aware of information
New model explains when the brain becomes aware of information
Scientists propose that periods of unconscious processing-during which the brain integrates information-precede brief moments of consciousness. When we watch a movie or hear an orchestra playing, it seems that we perceive images and sounds as a continuous stream of information. But a new study suggests that the brain makes information conscious only at certain moments of time, which are preceded by intervals of unconscious processing that can last up to half a second.

Outsmarting the PIN code
Outsmarting the PIN code
A PIN code is usually required at the checkout when paying large sums by credit card. ETH researchers have now discovered a flaw in the security system of some credit cards. Credit cards that enable contactless payments are extremely popular. Small amounts can be charged quickly and easily at the till, and the cards are considered safe because a security code is required to debit large sums.

A universal structural deformation in all heme proteins
Chemists and physicists from Switzerland and Germany have shown that the typical deformation of respiratory heme proteins also occurs in heme proteins not involved in the respiratory function. Image:A model of heme, which is an organic ring molecule surrounding an atom of iron and is a major component of hemoglobin in red blood cells.

"Jumping" DNA regulates human neurons
"Jumping" sequences of DNA, known as transposable elements, partner up with evolutionarily recent proteins to influence the differentiation and physiological functioning of human neurons. The human genome contains over 4.5 million sequences of DNA called "transposable elements", these virus-like entities that "jump" around and help regulate gene expression.

How bacteria adhere to fiber in the gut
How bacteria adhere to fiber in the gut
Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Scientists of the University of Basel and ETH Zurich published their results in the journal "Nature Communications".

Space debris observed for the first time during the day
Space debris observed for the first time during the day
Researchers at the University of Bern are the first in the world to succeed in determining the distance to a space debris object using a geodetic laser in daylight. The distance was determined on June 24, 2020 at the Swiss Optical Ground Station and Geodynamics Observatory Zimmerwald. The number of measurements can be multiplied thanks to the new possibility of observing space debris during the day.

Microbes working together multiply biomass conversion possibilities
Non-edible plants are a promising alternative to crude oil, but their heterogenous composition can be a challenge to producing high yields of useful products. Scientists from EPFL, the University of Cambridge, and the Bern University of Applied Sciences have developed a platform that combines different microorganisms that can make a dramatic difference.

Binding sites for protein-making machinery
Binding sites for protein-making machinery
ETH Zurich researchers can predict how tightly a cell's protein synthesis machinery will bind to RNA sequences - even when dealing with many billions of different RNA sequences. This binding plays a key role in determining how much of a specific protein is produced. The scientists are developing their prediction model using a combination of synthetic biology experiments and machine learning algorithms.

Protecting estuarine cities from rising sea levels
Protecting estuarine cities from rising sea levels
As climate change raises sea levels, estuarine cities are facing up to the dual threat of flooding and significant erosion. Research by a joint team from EPFL and the UNSW Sydney sheds new light on the hydrodynamic forces at play and paves the way for preventive strategies. Almost 60% of the global population lives near an estuary, and the list of estuarine cities features 21 of the world's 30 biggest urban centers, including New York and Tokyo.
