New approach to terpene syntheses
New approach to terpene syntheses
Terpenes are natural products that are often very difficult to synthesize in the laboratory. Chemists from the University of Basel have now developed a synthesis method that mimics nature. The decisive step takes place inside a molecular capsule, which enables the reaction. The findings were recently published Catalysis.

How resistant cancer cells can be fought
How resistant cancer cells can be fought
An international research team under the co-direction of the University of Bern and the Netherlands Cancer Institute (NKI) has discovered various mechanisms of resistance to cancer therapy. The findings help researchers to understand the self-repair of cancer cells after a therapy and thus help to fight resistant tumours more efficiently.

A novel antibiotic from weeds
A novel antibiotic from weeds
Researchers have discovered novel, antibiotically active chemical substances in a previously rarely explored site: the leaf of a common field weed. The findings show that this microcosm contains many still unknown natural products that could lead to new drugs. Many of the antibiotics used today were developed from natural products made by bacteria themselves in order to ward off other bacteria.

Soil bugs munch on plastics
Thin mulch films made of polyethylene are used in agriculture in numerous countries, where they cause extensive soil contamination. Researchers at ETH Zurich and Eawag have now identified an alternative: films made of the polymer PBAT biodegrade in soils. Our world is drowning in a flood of plastic.

Riding an e-bike promotes fitness and health - already after four weeks
Riding an e-bike promotes fitness and health - already after four weeks
The role of the e-bike in promoting health and fitness is comparable to that of a conventional bicycle. This was reported by researchers of the University of Basel in the Clinical Journal of Sport Medicine. In particular, overweight and untrained individuals can benefit from riding an e-bike. The starting point for the pilot study was the Bike to Work campaign, which has been running in Switzerland for ten years now and invites commuters to switch to their bicycles or e-bikes every year for a month.

An insect-inspired drone deforms upon impact
An origami-like drone developed at EPFL is flexible enough to absorb shocks without breaking before returning to its initial shape. This new type of drone, which was inspired by insect wings, draws on the advantages of both stiff and flexible structures. In recent years, robotics experts have taken a page from the traditional Japanese practice of origami and come up with light and flexible - and highly innovative - robots and drones.

EPFL uses excitons to take electronics into the future
EPFL uses excitons to take electronics into the future
EPFL researchers have developed a transistor based on excitons - a type of particle most people have not heard of - that is able to function at room temperature. This breakthrough could lead to a new breed of faster, more energy efficient and smaller electronics. Excitons could revolutionize the way engineers approach electronics.

Zika virus is infectious for a shorter time than previously thought
Zika virus (ZIKV) may be sexually transmissible for a shorter period than previously estimated, according to a systematic review published this week in PLOS Medicine by Michel Counotte and Nicola Low of the Institute of Preventive Medicine (ISPM), and colleagues from the World Health Organization, US Centers for Disease Control and National Institute of Allergy and Infectious Disease.

Material from PSI helps to check inconsistencies in the Big Bang theory
Material from PSI helps to check inconsistencies in the Big Bang theory
Shortly after the Big Bang, radioactive atoms of the type beryllium-7, among others, came into being. Today, throughout the universe, they have long since decayed and do not occur naturally, in contrast to their decay product lithium. Now researchers at the Paul Scherrer Institute PSI have helped to better understand the first minutes of the universe: They collected artificially produced beryllium-7 and made it into a sample that could be investigated.

Search engine for «smart wood»
Search engine for «smart wood»
Mark Schubert modifies wood properties with the aid of the enzyme laccase. However, the search for suitable ingredients is complex - a bit like trying to find the key to an unknown lock. Instead of long, expensive series of experiments, Schubert uses artificial intelligence as it gets him to the goal more quickly.

Mobile Phone Radiation may Affect Memory Performance in Adolescents
Mobile Phone Radiation may Affect Memory Performance in Adolescents
Radiofrequency electromagnetic fields may have adverse effects on the development of memory performance of specific brain regions exposed during mobile phone use. These are the findings of a study involving nearly 700 adolescents in Switzerland. The investigation, led by the Swiss Tropical and Public Health Institute (Swiss TPH), will be published on Monday, 23 July 2018 in the peer-reviewed journal Environmental Health Perspectives.

Aquatic research from an altitude of 800 km
Aquatic research from an altitude of 800 km
Thanks to Copernicus - the EU Earth Observation Programme initiated in 2014 - environmental researchers now have access to vast amounts of high-quality satellite data. As this is also invaluable for aquatic research, Eawag is currently expanding its capacity in the area of remote sensing. "That's probably the most successful proposal I've ever made!" says Professor Johny Wüest, his eyes sparkling.

Throwing shade on shade balls
Throwing shade on shade balls
Black plastic balls, which aim to reduce evaporation losses from open-air reservoirs under drought conditions, are not quite as efficient as previously assumed. Considerable quantities of water are already used in their production. Eawag researcher Dr. Erfan Haghighi has taken a close look at the water footprint of the shade balls together with his colleagues from Imperial College London and University of Twente.

Forget joysticks, use your torso to pilot drones
Your torso is more intuitive - and more precise - than joysticks for piloting drones, both simulated and real, according to a recent study by EPFL scientists. Work is already underway to implement this new body-machine-interface technology for search and rescue with drones. Imagine piloting a drone using the movements of your torso only and leaving your head free to look around, much like a bird.

Mystery of the Basel papyrus solved
Mystery of the Basel papyrus solved
Since the 16th century, Basel has been home to a mysterious papyrus. With mirror writing on both sides, it has puzzled generations of researchers. A research team from the University of Basel has now discovered that it is an unknown medical document from late antiquity. The text was likely written by the famous Roman physician Galen.

Tailor-made asphalt
Tailor-made asphalt
The one ideal asphalt for all conditions does not exist: climatic conditions, traffic frequencies and loads place different demands on the pavement. Another challenge: preparing old asphalt so that it can be used for new pavements. Thanks to Empa researchers, the design of the ideal asphalt for every type of road has finally become easier.

New control of cell division discovered
New control of cell division discovered
When a cell divides, its constituents are usually evenly distributed among the daughter cells. UZH researchers have now identified an enzyme that guarantees that cell constituents that are concentrated in organelles without a membrane are properly distributed. Their discovery opens up new opportunities for the treatment of cancer, neurodegenerative diseases, aging processes and viral infections.

Glyphosate eliminated by cyanobacteria
Glyphosate eliminated by cyanobacteria
Researchers from Agroscope and Eawag have discovered that, under certain conditions, the herbicide glyphosate is rapidly degraded in Lake Greifen (Greifensee). The evidence strongly suggests that this is due to cyanobacteria using the substance as an alternative source of phosphorus. Glyphosate is frequently in the headlines: expert committees disagree as to whether the herbicide is carcinogenic to humans, authorities debate whether its use should be approved.
