Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team ...

This week’s tip is adapted from a commencement speech I gave recently at the University of Pennsylvania. You can watch the entire speech here. The paramecium is an amazing organism. It survives and ...

The mating process is one of the most important mechanisms for maintaining genetic variation in natural populations. The emergence of sexual reproduction turned out to be the most important ...

THE suggestion made by Gunn and Walshe 1, that the avoiding reaction of Paramecium fits into the scheme of klino–kinesis, receives some support from the behaviour of the animal in a uniform high ...

Paramecium are ciliates, members of a phylum of protists that possess both germline and somatic genomes housed in functionally distinct nuclei — the micronucleus and macronucleus, respectively. During ...

Conjugation (or mating) of ciliates is a unique phenomenon among living beings. They have sex not for reproduction or pleasure — they seek to increase genetic variation. Scientists from St Petersburg ...

There are more than 50,000 different types of microorganisms known to scientists -– and they discover more every year. In a basement laboratory at the University of Pennsylvania, two robotocists have ...

The paramecium is an amazing organism. It survives and thrives using just one basic principle: If things are getting better, keep swimming in that direction, and if not, change course. If the water’s ...
