Printing tiny, high-precision objects in a matter of seconds
Researchers at EPFL have developed a new, high-precision method for 3D-printing small, soft objects. The process, which takes less than 30 seconds from start to finish, has potential applications in a wide range of fields, including 3D bioprinting. It all starts with a translucent liquid. Then, as if by magic, darker spots begin to form in the small, spinning container until, barely half a minute later, the finished product takes shape.

Extinct Giant Turtle Had Horned Shell of up to Three Meters
Extinct Giant Turtle Had Horned Shell of up to Three Meters
Paleobiologists from the University of Zurich have discovered exceptional specimens in Venezuela and Colombia of an extinct giant freshwater turtle called Stupendemys. The carapace of this turtle, which is the largest ever known, measured between 2.4 to almost 3 meters. Moreover, the shell of male Stupendemys had horns ' a rare feature in turtles.

Algorithms for identifying new
Algorithms for identifying new "cancer genes"
It is estimated that the number of cancer cases worldwide will double by 2040. This makes the search for genes that cause cancer even more important. A team of researchers from the University of Bern and Inselspital, University Hospital Bern, has now developed algorithms that massively simplify the hunt for "cancer genes" in a poorly understood part of our genome.

New quasiparticle unveiled in room temperature semiconductors
New quasiparticle unveiled in room temperature semiconductors
Physicists from Switzerland and Germany have unveiled fingerprints of the long-sought particle known as Mahan exciton in the room temperature optical response of the popular methylammonium lead halide perovskites. The optical properties of semiconductors are governed by the so-called 'excitons', which are bound pairs of negative electrons and positive holes.

Bacteria under the microscope: a new growth model for tuberculosis
Bacteria under the microscope: a new growth model for tuberculosis
New research has shed light on how mycobacteria grow. This discovery could explain why some members of this family of single-celled organisms, which includes the bacillus that causes tuberculosis, can develop resistance to antibiotics For centuries, scientists have peered down the lens of a microscope and watched as bacteria - some circular, others rod-shaped - multiply before their eyes.

Connecting two important processes in gene expression
Connecting two important processes in gene expression
RNA decay plays a fundamental role in gene expression by controlling the quality and quantity of messenger RNAs. However, it has proved difficult to study and is still shrouded in mystery. Scientists from the Bühler group now uncovered key targets, components and functions of mammalian RNA decay pathways, and found that RNA decay is tightly connected to another crucial stage of gene expression: protein synthesis (translation).

Observe how microorganisms interact
Observe how microorganisms interact
Microbial communities are known to be indispensable for our planet. But surprisingly little is known about how they function. Researchers at the Swiss Federal Institute of Aquatic Science and Technology and ETH Zurich are now shedding a little light on this subject. Without them there would be on oxygen, humans and animals could not digest, and the material cycles on Earth would come to a halt: Microorganisms.

Personalized cancer vaccines
Personalized cancer vaccines
The only therapeutic cancer vaccine available on the market has so far showed very limited efficacy in clinical trials. EPFL researchers are currently working on an alternative. They have developed a platform that allows a cancer vaccine to be delivered to a precise location and stimulate the immune system in a safe way - thereby overcoming one of the two obstacles to creating an effective vaccine.

New world map of fish genetic diversity
New world map of fish genetic diversity
An international research team has studied genetic diversity among fish around the world for the first time. Their research produced a map that will serve as a tool in improving the protection of species and genetic diversity in the future. In a population of animals or plants, genetic diversity can decline much more quickly than species diversity in response to various stress factors: disease, changes to habitat or climate, and so on.

Geothermal energy: drilling a 3,000 metres deep well
Geothermal energy: drilling a 3,000 metres deep well
Researchers from the University of Geneva have studied the seismic activity recorded during the drilling of a geothermal well and shown that it did not spark any major earthquake. Although stopping climate change is challenging, it is imperative to slow it down as soon as possible by reducing greenhouse gas emissions.

Without them there would be no oxygen, humans and animals could not digest, and the material cycles on Earth would come to a halt: Microorganisms. Microbial communities also carry out important functions in aquatic systems. These are often the result of interactions between organisms within the community.

Biodiversity yields financial returns
Biodiversity yields financial returns
Farmers could increase their revenues by increasing biodiversity on their land. This is the conclusion reached by an interdisciplinary research team including the fields of agricultural sciences, ecology and economics at ETH Zurich and other universities. Many farmers associate grassland biodiversity with lower yields and financial losses.

CHEOPS space telescope takes its first pictures
Next milestone in the commissioning of CHEOPS: After the successful opening of the space telescope cover on January 29, 2020, CHEOPS has now taken its first images of the sky. CHEOPS is a joint mission of the European Space Agency (ESA) and Switzerland, led by the University of Bern, in collaboration with the University of Geneva.

A novel formulation to explain heat propagation
A novel formulation to explain heat propagation
Researchers at EPFL and MARVEL have developed a novel formulation that describes how heat spreads within crystalline materials. This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent.

Breathing may change your mind about free will
Is free will just an illusion? For decades, a signal from the brain called the "readiness potential" has been interpreted to mean that free will may be an illusion. Backed by signals from the brain and lungs, EPFL scientists have discovered that the readiness potential is in fact coupled to breathing and that acts of free will happen as you exhale - providing an unexpected perspective on free will.

New Understanding of Childhood Immune Systems May Improve Vaccine Efficacy
New Understanding of Childhood Immune Systems May Improve Vaccine Efficacy
In lowand middle-income countries, children have the greatest need for protection afforded by vaccination due to a higher incidence of infectious diseases. However, the vaccines for these children often show a lower efficacy when compared to similar populations in high-income settings. A new study by the Swiss Tropical and Public Health Institute (Swiss TPH) and partners from the Babraham Institute, ISGlobal and others published yesterday in Science Translational Medicine reveals that the immune system of children varies according to age, location and anaemia status.

Fast and cheap track to new types of solar cells
Fast and cheap track to new types of solar cells
The semiconductor perovskite is seen as a new hope to bring the production price of solar cells down below that of silicon used so far. Empa is developing new manufacturing processes to make perovskite solar cells not only cheaper but also faster to produce and make them ready for industrial use. Since the development of the first perovskite solar cell in 2009, its efficiency is now equal to that of a conventional silicon cell.

Redrawing the map of cancer genome research
Cancer's genetic causes are more diverse than previous scientific studies have indicated - a conclusion reached by researchers from ETH Zurich and University Hospital Zurich. Through their participation in an international research collaboration, they helped compile the most comprehensive catalogue to date of gene alterations associated with cancer.
