Synthetic phages with programmable specificity
Synthetic phages with programmable specificity
ETH researchers are using synthetic biology to reprogram bacterial viruses - commonly known as bacteriophages - to expand their natural host range. This technology paves the way for the therapeutic use of standardized, synthetic bacteriophages to treat bacterial infections. Bacteriophages ("phages" for short) are viruses that infect bacteria.

Removing liver tumors safely, noninvasively and efficiently
Removing liver tumors safely, noninvasively and efficiently
Many liver tumors have long been difficult or impossible to remove. Since 2015, however, it has been possible to treat these tumors by combining noninvasive surgical techniques, radiological imaging and a navigation system. For the first time, a new study by University of Bern and Inselspital, Berne University Hospital has impressively demonstrated the success of this technique.

Milk from Teeth: Dental Stem Cells Can Generate Milk-Producing Cells
Milk from Teeth: Dental Stem Cells Can Generate Milk-Producing Cells
Stem cells of the teeth can contribute to the regeneration of non-dental organs, namely mammary glands. According to a new study from researchers at the University of Zurich, dental epithelial stem cells from mice can generate mammary ducts and even milk-producing cells when transplanted into mammary glands.

Analyzing gut bacteria more accurately
The microorganisms in our intestines could be linked to certain diseases such as Alzheimer's and diabetes. Researchers from the AD-gut consortium have developed a novel method - combining optical DNA mapping and statistics - for accurately distinguishing and rapidly identifying the various species in the microbiota.

Could mathematics help to better treat cancer?
Could mathematics help to better treat cancer?
Using the information theory, researchers at UNIGE aim to better understand the cancerous development of cells through a mathematical approach and propose innovative therapeutic strategies. The development and survival of living beings are linked to the ability of their cells to perceive and respond correctly to their environment.

The Effects of the Scorching Summer of 2018 on Health
The Effects of the Scorching Summer of 2018 on Health
The Swiss Tropical and Public Health Institute (Swiss TPH) analysed the health consequences of the hot and dry summer of 2018 for the Federal Office for the Environment (FOEN). The results were published today in the report "Heat and Drought in Summer 2018 - Effects on Humans and the Environment". The report shows that heat and drought had negative impacts on human health, forests, agriculture, water and glaciers.

Bacteria must be "stressed out" to divide
Bacterial cell division is controlled by both enzymatic activity and mechanical forces, which work together to control its timing and location, a new study from EPFL finds. A new study from EPFL scientists has found that bacteria use mechanical forces to divide, along with biological factors. The research, led by the groups of John McKinney and Georg Fantner at EPFL, came after recent studies suggested that bacterial division is not only governed by biology, but also by physics.

Special cells contribute to regenerate the heart in Zebrafish
Special cells contribute to regenerate the heart in Zebrafish
It is already known that zebrafish can flexibly regenerate their hearts after injury. An international research group led by Prof. Nadia Mercader of the University of Bern now shows that certain heart muscle cells play a central role in this process. The insights gained could be used to initiate a similar repair process in the human heart.

Monitoring the corrosion of bioresorbable magnesium
Monitoring the corrosion of bioresorbable magnesium
ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of tailored materials for temporary implant applications.

Protein in Blood Protects against Neuronal Damage after Brain Hemorrhage
Protein in Blood Protects against Neuronal Damage after Brain Hemorrhage
Patients who survive a cerebral hemorrhage may suffer delayed severe brain damage caused by free hemoglobin, which comes from red blood cells and damages neurons. Researchers at the University of Zurich and the UniversityHospital Zurich have now discovered a protective protein in the body called haptoglobin, which prevents this effect.

EPFL is developing next-generation soft hearing implants
EPFL is developing next-generation soft hearing implants
Working with clinicians from Massachusetts Eye and Ear and Harvard Medical School, a team of EPFL researchers has developed a conformable electrode implant that will allow people with a dysfunctional inner ear to hear again. This new device could replace existing auditory brainstem implants, which have a number of shortcomings.

Diabetes: a next-generation therapy soon available?
Diabetes: a next-generation therapy soon available?
By identifying a protein that helps regulate blood glucose and lipids, researchers at UNIGE hope for the rapid development of treatments more effective than current insulin therapy. Insulin, a hormone essential for regulating blood sugar and lipids, is normally produced by pancreatic - cells. In many people with diabetes, however, pancreatic cells are not (or no longer) functional, causing a chronic and potentially fatal insulin deficiency that can only be controlled through daily insulin injections.

Raw Meat-Based Diets for Pets Pose a Health Risk for Humans
Multidrug-resistant bacteria are found in half of all dog foods made from raw meat, researchers from the University of Zurich have found. Feeding pets a diet of raw meat, also known as a "BARF" diet, is a growing trend. The resistant bacteria in the raw food can be transmitted to the pets - and thus also to humans.

The cholera bacterium can steal up to 150 genes in one go
The cholera bacterium can steal up to 150 genes in one go
EPFL scientists have discovered that predatory bacteria like the cholera pathogen can steal up to 150 genes in one go from their neighbors. The study sheds light on one of the most fundamental mechanisms of horizontal gene transfer. In 2015, EPFL researchers led by Melanie Blokesch published a seminal paper in Science showing that the bacterium responsible for cholera, Vibrio cholerae , uses a spring-loaded spear to literally stab neighboring bacteria and steal their DNA.

On Your Medicine’s Secret Service
Whether a wound heals well under a dressing cannot be seen from the outside. Empa researchers are now enabling a view through the bandage à la James Bond. The refined application of terahertz radiation could promote the analysis of multi-layered tissues for medical purposes and be used for wound treatment or the diagnostics of blood vessel plaques.

The Screw That Dissolves
The Screw That Dissolves
Where bones fracture, surgeons often have to join the fragments with implants. Magnesium orthopaedic screws, which over time dissolve in the body, spare patients another operation after healing is completed and reduce the risk of infection. What happens inside the body during this process, though, is still largely unknown.
