Eine gewaltige Schlammlawine begrub vor wenigen Tagen ganze Dörfer in Indien. Forscher, auch solche von der Uni Zürich, haben nun den wahrscheinlichen Hergang rekonstruiert.

Die europäischen Länder wollen 2050 klimaneutral sein. Dennoch geben sie 70 Milliarden Euro für fossile Brennstoffe und neue Pipelines aus. Wie passt das zusammen?

Um CO2-Emissionen zu drosseln, will Bill Gates neue Reaktoren bauen und Forscher fordern längere Laufzeiten. Ein Tropfen auf den heissen Stein, sagen Experten.

Finden Sie heraus, ob Sie für Missionen ins Weltall geeignet sind.

Eine neue Studie erklärt den «Third Person Effect»: Manipulierende Aussagen verfangen offenbar, weil Menschen überzeugt sind, dass alle anderen daran glauben.

Die Europäische Raumfahrtagentur sucht Kandidatinnen (und Kandidaten) für ihr Astronautenprogramm. Erstmals werden auch Parastronauten rekrutiert – Personen mit körperlichen Beeinträchtigungen.

Es sei äusserst schwierig, aber nicht unmöglich: Der Microsoft-Gründer hat einen klaren Plan formuliert, wie eine Klimakatastrophe abgewendet werden kann.

Seit dem Brexit steigt die Nervosität in Nordirland – wo liegen die historischen Wurzeln dieses jahrhundertealten Konflikts zwischen Katholiken und Protestanten?

Bei kalten Temperaturen verengen sich die Herzkranzgefässe – das erhöht die Infarktgefahr.

Neurodermitis ist eine der häufigsten Hautkrankheiten, besonders bei Kindern und Jugendlichen. Was kann man dagegen tun?

Wie hat sich die Pandemie im vergangenen Frühjahr in Europa ausgebreitet? Ein Forscherteam um die Biostatistikerin Tanja Stadler von der ETH Zürich kommt zu einer klaren Antwort.

An international team of researchers reports the development of a graphene-based optical modulator that proves outstanding performances in modulation efficiency, stability and high speed.

Scientists have suggested using innovative thin films to considerably reduce friction and thus increase the durability of surfaces in mechanisms. This discovery can be important for many fields, from medicine to space technologies.

3D-bioprinting method enables advanced tissue fabrication by using a yield-stress support bath that holds bioinks in place until they are cured and works with a wide array of bioinks.

A research team has developed a transparent amorphous silicon that transmits visible light - which permits us to distinguish the colors of objects - enabling the development of paper-thin lenses usable in head-mounted displays that show virtual and augmented reality images in real time.

Scientists develop a relatively simple synthesis strategy to produce high-performance tin telluride nanosheets, a promising thermoelectric material.

Scientists looked into the latest research to find the most exciting potential applications of graphene in point-of-care tests. This includes diagnostic tests for SARS-CoV-2, the virus responsible for COVID-19, but also detecting other viruses, bacteria and even cancerous tumours.

In January 2021, Nanosurf acquired Scuba Probe Technologies, a startup company that develops atomic force microscopy probes for electrical measurements in liquid.

By creating kinks in the structure of graphene, researchers have made the nanomaterial behave like a transistor, and have shown that when a strip of graphene is crinkled in this way, it can behave like a microchip, which is around 100 times smaller than conventional microchips.

A major challenge in the development of implantable and ingestible biomedical electronic devices is the limited lifetime of their power sources. The energy requirements of these devices are highly dependent on their application and the complexity of the required electrical systems. The power unit, which is composed of one or more energy sources - batteries, energy-harvesting, and energy transfer - as well as power management circuits, supplies electrical energy to the whole system.

Researchers have demonstrated that nanoengineered biodegradable microcapsules can guide the development of hippocampal neurons in an in vitro experiment. The microcapsules deliver nerve growth factor, a peptide necessary for neuron growth.

New method for growing cyanobacteria under Mars-like conditions.

Researchers detail how they developed a nano-barrier and custom-built deposition system that bonds to the surface of polymer or composite materials, protecting them from erosion in low-Earth orbit.

Injecting patients with a gel that would dissolve over several months could replace the need to administer daily or weekly shots. But to make this possible, researchers first had to create a Jello-like substance that could defy one of the fundamental laws of nature.

The 'sloshing' of a quantum fluid comprised of light and matter reveals superfluid properties. A team of physicists have successfully created sloshing quantum liquids in a 'bucket' formed by containment lasers.

A team of researchers has investigated the strength of dark matter scattered across the smallest galaxies in the universe using stellar kinematics. They discovered that the strength of dark matter is quite small, suggesting that dark matter does not easily scatter together.

Materials having excess electrons are typically conductors. However, moire patterns -- interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern -- can suppress electrical conductivity.

Engineers have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer?s levels of glucose as well as lactate, alcohol or caffeine.

Engineers develop polymer cores that redirect light from any source to solar cells.

Nanoscientists develop adaptive microelectronics that can move independently according to sensor data and align themselves specifically for activities - possible applications in biomedicine and bioneural interfacing.

New theory explains possible origin of the Armageddon-causing object.
