No-scalpel vasectomies by skilled surgeons may speed recovery

...perience with the standard vasectomy technique and three had experience with the no-scalpel method. Inexperienced surgeons received training in the no-scalpel technique. In this study, men who received no-scalpel vasectomies had less bleeding, bruising, infection and pain during surgery and follow-up. ...

Researchers discover surprising drug that blocks malaria

...ished in PLoS Medicine. Malaria, one of the top three deadliest diseases in the developing world, is resurging worldwide because of drug resistance and the lack of an effective vaccine, Haldar said. Jamaica recently reported an outbreak of malaria after it had been eradicated in that country for 50 year...

UF scientists discover new genus of frogmouth bird in Solomon Islands
