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).

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.

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.

Our carbon footprint is highly impacted by how we live
Swiss households have excessively large carbon footprints. However, that footprint depends more on socio-economic status than location - whether the household is in the countryside or the city - because people travel more in the country but consume more in cities. Swiss households enjoy a high standard of living, but this results in a large carbon footprint.

Legacy effects of persistent organic pollutants
Legacy effects of persistent organic pollutants
Hexachlorobenzene (HCB), formerly widely used as a fungicide, is one of the so-called dirty dozen - the first twelve toxic chemicals whose use was banned worldwide in 2004 under the Stockholm Convention on Persistent Organic Pollutants. However, due to its chemical structure, this compound is extremely stable and is only broken down very slowly in nature.

Could resetting our internal clocks help control diabetes?
Could resetting our internal clocks help control diabetes?
Researchers from the University of Geneva and HUG were able to demonstrate the link between disturbances of the circadian clocks in pancreatic cells and type 2 diabetes, then to correct these disturbances. The circadian clock system (from Latin "circa diem", about a day) allows the organisms to anticipate periodical changes of geophysical time, and to adjust to these changes.
