Evolution of a species also involves the bacteria it carries

Animals live in close association with microorganisms, carrying beneficial bacteria while coping with pathogenic infections. Now, in a study published this week in PLoS Genetics, researchers from Instituto Gulbenkian de Ciência ...

A molecular alarm clock awakens resting ovules

At the start of reproductive life an ovary contains, on average, several thousands of immature ovules in a resting state that can last for several decades. But how does each resting ovule know that it is time to prepare for ...

Origin of the long body of snakes discovered

For many years, researchers have been trying to understand the origin of the exceptionally long trunks that characterize the body of snakes. This is a mystery in terms of animal development that can shed light on the mechanisms ...

A critical inheritance from dad ensures healthy embryos

An important feature for life is what embryos receive from mom and dad upon fertilization. Oddly enough, centrioles, the structures responsible for cell division and flagella movement, are given by the paternal gamete. How ...

The cell copying machine: How daughters look like their mothers

Tiny structures in our cells, called centrioles, control both cell division and motility. The number of these structures is highly monitored, with deviations causing infertility, microcephaly and accelerating cancer. But ...

Social structure matters in species conservation

Many animal species, including humans, live and breed in groups with complex social organizations. The impact of this social structure on the genetic diversity of animals has been a source of disagreement between scientists. ...

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 ...
