Using microfluidics to improve genetics research
Using microfluidics to improve genetics research
Scientists at EPFL have developed a technique that can be a game-changer for genetics by making the characterization of DNA-binding proteins much faster, more accurate, and efficient.  Genes hold the DNA code for producing all the proteins of the cell. To begin this process, genes require a huge family of DNA-binding proteins called transcription factors, which are of enormous interest to biologists today.

Putting chromosomes through the shredder
Putting chromosomes through the shredder
When a certain human enzyme is left uncontrolled, it breaks up chromosomes into tiny pieces. This is damaging to cells, but useful for killing tumours. ETH researchers have now come to understand the underlying mechanism. Our cells contain the enzyme MUS81; this is called on in emergencies, for example, when cells are unable to replicate because the DNA-replication machinery gets tangled up in strands of DNA.

In a simple way to great complexity
ETH microbiologists have succeeded in showing that nature produces one of the most complex known bioactive natural products in a staggeringly simple way.

From photosynthesis to new compounds for eye diseases
From photosynthesis to new compounds for eye diseases
Researchers have succeeded in using X-rays to minutely observe a photosynthesis reaction and produce a movie of the event. The findings will aid understanding of similar processes in the human eye. Plants and algae are not alone in undergoing photosynthesis. Some bacteria also use energy from sunlight to grow and reproduce.

Aging & cancer: An enzyme protects chromosomes from oxidative damage
Aging & cancer: An enzyme protects chromosomes from oxidative damage
EPFL scientists have identified a protein that caps chromosomes during cell division and protects them from oxidative damage and shortening, which are associated with aging and cancer. When cells divide, they pack up all of their genetic material in the tightly wrapped chromosomes. The ends of our chromosomes have a unique structure, named a telomere.

How complex cells originated
How complex cells originated
Media releases, information for representatives of the media Media Relations (E) Mitochondria are the ‘power plants' of complex cells. In order to provide the cell with energy they need protein building blocks, which are imported from the outside. Over billions of years the ‘protein import machines' necessary for this process have developed differently than previously assumed, as biochemists in Bern have discovered.

New weapon against Diabetes
New weapon against Diabetes
Researchers have used the simplest approach yet to produce artificial beta cells from human kidney cells. Like their natural model, the artificial cells act as both sugar sensors and insulin producers. Researchers led by ETH Professor Martin Fussenegger at the Department of Biosystems Science and Engineering (D-BSSE) in Basel have produced artificial beta cells using a straightforward engineering approach.

"Pulling" bacteria out of blood
Magnets instead of antibiotics could provide a possible new treatment method for blood infection. This involves the blood of patients being mixed with magnetic iron particles, which bind the bacteria to them after which they are removed from the blood using magnets.

Miraculous proliferation
Miraculous proliferation
Bacteria able to shed their cell wall assume new, mostly spherical shapes. ETH researchers have shown that these cells, known as L-forms, are not only viable but that their reproductive mechanisms may even correspond to those of early life forms. Researchers from a group led by ETH professor Martin Loessner discovered a few years ago that rod-shaped Listeria can become spherical.

Gene "bookmarking" regulates the fate of stem cells
A protein that stays attached on chromosomes during cell division plays a critical role in determining the type of cell that stem cells can become. The discovery, made by EPFL scientists, has significant implications for stem cell biology and their use in medicine. When cells divide, DNA is neatly wrapped up into chromosomes, and the normal expression of genes into proteins stops until the new cells are formed.

Honey bee teenagers speed up the ageing process of their elders
Honey bee teenagers speed up the ageing process of their elders
Bern, 06.12.2016 - Honey bee (Apis mellifera) colonies are complex societies, in which work is not distributed by a central power. How tasks are allocated among workers is still poorly understood. A research team from the Swiss Bee Research Center at Agroscope and the Institute of Bee Health at the University of Bern (both Switzerland), discovered that young adults influence this process by promoting older individuals to perform duties outside the hive, which shortens their life expectancy.

High-precision magnetic field sensing
High-precision magnetic field sensing
Scientists have developed a highly sensitive sensor to detect tiny changes in strong magnetic fields. The sensor may find widespread use in medicine and other areas. Researchers from the Institute for Biomedical Engineering, which is operated jointly by ETH Zurich and the University of Zurich, have succeeded in measuring tiny changes in strong magnetic fields with unprecedented precision.

An agent used to treat psoriasis may be aimed at the wrong target
An agent used to treat psoriasis may be aimed at the wrong target
Common psoriasis, also called psoriasis vulgaris, is an inflammatory skin disease that is characterized by severely scaling skin in areas ranging from small to palm-sized. The disease is estimated to affect between two and three percent of all Europeans. The cause is said to be immune system malfunctions: the underlying mechanism involves the immune cells reacting to skin cells.

Starch from yeast
Starch from yeast
Researchers at ETH Zurich have produced starch in yeast - the first time this has been achieved in a non-plant organism. The new model system now makes it easier for them to investigate how starch is formed and what role is played by the enzymes involved. In future, it may be possible to use yeast to trial specific modifications of starch.

Protein packaging may cause the immune attacks of type-1 diabetes
Protein packaging may cause the immune attacks of type-1 diabetes
Type-1 diabetes occurs when immune cells attack the pancreas. EPFL scientists have now discovered what may trigger this attack, opening new directions for treatments. Type-1 diabetes is the rarest but most aggressive form of diabetes, usually affecting young children and adolescents. The patient's own immune cells begin to attack the cells in the pancreas that make insulin, eventually eliminating its production in the body.

Smartwatches connect intensive care doctors and their patients
Smartwatches connect intensive care doctors and their patients
Researchers have come up with a way to link a smartwatch to the metabolic monitors used with patients in intensive care. If the sensors - which were developed at EPFL - detect an anomaly, the doctor on duty receives an alert anywhere in the hospital. Intensive care doctors may soon be able to wear a smartwatch connected to the system that keeps tabs on the vital parameters of patients in the intensive care unit.

Red squirrels in the British Isles are infected with leprosy bacteria
Red squirrels in the British Isles are infected with leprosy bacteria
Microbiologists at EPFL and the University of Edinburgh have discovered that red squirrels in Britain and Ireland carry the two bacterial species that cause leprosy in humans. Once rampant in medieval Europe, leprosy dramatically declined by the end of the Middle Ages for reasons that are still unclear.
