All-female hybrid fish species uses males for better genetics
Oct 17, 2016
Some species are comprised of female-only members, giving themselves a competitive advantage over species that produce both male and female offspring. Since the females are capable of bearing offspring, they can quickly outnumber ...
Human transport has unpredictable genetic and evolutionary consequences for marine species
Oct 14, 2016
New research, led by the University of Southampton, has found that human activities such as shipping are having a noticeable impact on marine species and their native habitats.
Feral chickens spread light on evolution
Sep 30, 2016
Different genes are involved during the adaptation of a domestic animal to life in the wild than when a wild animal becomes domesticated. This is the conclusion of a study led by a researcher at Linköping University in Sweden ...
Smallest-reported artificial virus could help advance gene therapy
Sep 21, 2016
Gene therapy is a kind of experimental treatment that is designed to fix faulty genetic material and help a patient fight off or recover from a disease. Now scientists have engineered the smallest-reported virus-like shell ...
First accurate simulation of a virus invading a cell
Sep 12, 2016
For the first time, scientists know what happens to a virus' shape when it invades a host cell, thanks to an experiment by researchers at Penn State College of Medicine and University of Pittsburgh School of Medicine. Understanding ...
Researchers discover a gene that is essential for the DNA-replication process
Sep 07, 2016
Millions of human cells are constantly dividing to repair tissue damage and ensure continuity. This is one of the most complex cellular processes, and in order for it to be successful, cells must produce a copy of their genetic ...
Placenta in females, muscle mass in males: The dual heritage of a virus
Sep 02, 2016
It is known that genes inherited from ancient retroviruses are essential to the placenta in mammals, a finding to which scientists in the Laboratoire Physiologie et Pathologie Moleacuteculaires des Retrovirus Endogenes et ...
Newly discovered multicomponent virus is the first of its kind to infect animals
Aug 25, 2016
For the first time, a multicomponent virus—which contains different segments of genetic material in separate particles, rather than a single strand of genetic material—has been found that is capable of infecting animals, ...
Teasing out the microbiome of the Kansas prairie
Jul 29, 2016
The Kansas prairie seems like the very picture of beauty and simplicity, with undulating fields of corn and wheat stretching as far as the eye can see.
How a cold gets into cells
Jun 20, 2016
Viruses smuggle their genetic material into our cells. How this actually works is currently being investigated at TU Wien (Vienna) using a new combination of analysis methods.
