Vitamin A may play a central role in stem cell biology and wound repair
When a child falls off her bike and scrapes her knee, skin stem cells rush to the rescue, growing new epidermis to cover the wound. But only some of the stem cells that will ultimately patch her up are normally dedicated ...

Researchers reveal how a virus hijacks insect sperm: May help control disease vectors and pests
A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria ...

Study on mating behaviors offers clues into the evolution of attraction
Sparks fly when a female nematode meets her mate in a Petri dish. Tracking him by smell, she beelines over and is pregnant within moments of physical contact. But for the hermaphroditic version of these tiny roundworms, it's ...

CRISPRlnc: New lncRNA-specific SgRNA design method proposed
Long non-coding RNAs (lncRNAs) are non-protein-coding transcripts. Currently, CRISPR/Cas9 is a promising RNA-guided genome editing technology consisting of a Cas9 nuclease and a single-guide RNA (sgRNA). Considering the significant ...
