(Phys.org)—Among other things, the egg is optimized to process the sperm genome. The cytoplasmic factors that make this possible also give the egg the ability to reprogram the nuclei from other kinds of cells if these nuclei ...
(Phys.org)—Researchers affiliated with several institutions in France have found that a species of parasitic wasp uses a virus as a bioweapon to stun a host ladybug into serving as a guard for its offspring. In their paper ...
(Phys.org)—A team of researchers with members from New Zealand, Czech Republic and the U.S. has documented for the first time an example of an aviary egg that has iridescence. In their paper published in Journal of the ...
(Phys.org) —A pair of researches with Kyoto University has found how the queen of one species of termite, Reticulitermes speratus, ensures her genetic lineage continues by creating duplicate copies of herself. In their ...
A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications do not ...

A team of biology researchers with members from Australia, the U.S., Czech Republic and the U.K. has found a correlation between eggshell color and thickness and the amount of light that shines on the eggs during incubation. ...
(Phys.org) —A trio of researchers has found that glassfrogs (Hyalinobatrachium fleischmanni) tend to hatch early if their male parent doesn't keep them hydrated. In their paper published in Proceedings of the Royal Society ...
(Phys.org) —A team of Canadian and Singaporean researchers has discovered that remnants of ancient viral DNA in human DNA must be present for pluripotency to occur in human stem cells. In their paper published in the journal ...
(Phys.org) —A pair of researchers from the University of Edinburgh has found that a certain type of beetle mother engages in offspring cannibalism when pestered too much. In their paper published in Behavioral Ecology, ...
A newly discovered fossil reveals the evolutionary adaptations of a 165-million-year-old proto-mammal, providing evidence that traits such as hair and fur originated well before the rise of the first true mammals. The biological ...
