New strategy to protect healthy gut microbes from antibiotics

Gut microbes promote human health by fighting off pathogens, but they also contribute to diseases such as diabetes and cancer. A study published March 19th by Cell Reports reveals a potential strategy for tipping the balance ...

Skeleton of cells controls cell multiplication

A research team from Instituto Gulbenkian de Ciencia (IGC; Portugal), led by Florence Janody, in collaboration with Nicolas Tapon from London Research Institute (LRI; UK), discovered that the cell's skeleton can trigger the ...

Too much of a good thing: Extra genes make bacteria lethal

We, as most animals, host many different beneficial bacteria. Being beneficial to the host often pays off for the bacteria, as success of the host determines the survival and spread of the microbe. But if bacteria grow too ...

Body size requires hormones under control

The proper regulation of body size is of fundamental importance, but the mechanisms that stop growth are still unclear. In a study now published in the scientific journal eLife, a research group from Instituto Gulbenkian ...

Gluing chromosomes at the right place

During cell division, chromosomes acquire a characteristic X-shape with the two DNA molecules (sister chromatids) linked at a central "connection region" that contains highly compacted DNA. It was unknown if rearrangements ...

Measuring the number of protein molecules inside cells

The identification of the genes and proteins involved in a biological process, as well as the way they interact, are essential for the understanding of that process. However, often little is known about the dimensions of ...

Cell division speed influences gene architecture

Speed-reading is a technique used to read quickly. It involves visual searching for clues to meaning and skipping non-essential words and/ or sentences. Similarly to humans, biological systems are sometimes under selective ...

Finding how many Coquerel's sifaka exist

In a study now published in the American Journal of Primatology, Célia Kun-Rodrigues and Jordi Salmona, from Lounès Chikhi's laboratory at the Instituto Gulbenkian de Ciência (IGC) provide the first abundance estimates ...
