Study Brings Universal Flu Vaccine a Step Closer

September 23, 2013 11:29 am Videos Comments

Scientists have moved closer to developing a universal flu vaccine by using the 2009 swine flu pandemic to study why some people seem to resist severe illness. Researchers asked volunteers to donate blood samples just as the pandemic was getting underway and also asked the volunteers to report any symptoms they experienced over the next two flu seasons.

Functioning Gears Found in Nature for the First Time

September 13, 2013 11:17 am Videos Comments

Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect- showing that evolution developed interlocking cogs long before we did. The juvenile Issus has hind-leg joints with curved cog-like strips of opposing “teeth” that intermesh, rotating like mechanical gears to synchronize the animal’s legs when it launches into a jump.
