The days of invasive crazy ants — whose supercolonies can support millions upon millions of the fierce insects — may be numbered. That's because a deadly fungus that uses spring-loaded harpoonlike barbs to pierce the ants' gut cells is wiping out their colonies across the Southeastern United States. That's not a bad thing. Tawny crazy ants (Nylanderia fulva), which are originally from South America, have over the past two decades become an increasingly problematic pest species and a threat to local wildlife in the U.S., by creating vast supercolonies.

The type of blood coursing through your veins is likely different from the blood in your friends and maybe even your family. Knowing your blood type is important for blood transfusions and other medical purposes, which raises a question: Why do humans have different blood types? There are four main blood groups: A, B, AB and O. Each is defined by which antigens are present on the surface of red blood cells. Type A blood has the A antigen on red blood cells, B has the B antigen, AB has both and O has neither. Full Story: [Live Science]( (3/28)

A brain structure called the amygdala grows too fast in babies who are diagnosed with autism by age 2, a new study suggests. The study researchers found that this overgrowth occurs between 6 and 12 months of age, before children are typically diagnosed with autism. The findings, published Friday (March 25) in The American Journal of Psychiatry, suggest that therapies for children at high risk of autism may have the best chance of working if they start in infancy.

If men take metformin, a common type 2 diabetes drug, during a critical period of sperm development, their offspring may be more likely to develop birth defects, a large study suggests. In particular, the study found that male babies born to fathers who took metformin during this critical period had a higher risk of genital birth defects than babies whose fathers took metformin outside of that key time window or had never taken the drug. The new research was published Monday (March 28) in the journal Annals of Internal Medicine. Full Story: [Live Science]( (3/28)

Astronomers have confirmed that a "potentially hazardous" asteroid is set to make its closest-ever approach to Earth this Friday (April 1). However, there is no need to panic; astronomers say the massive space rock will miss us by around 4.6 million miles (7.4 million kilometers). The asteroid, known as 2007 FF1, is between 360 feet and 656 feet (110 and 260 meters) in diameter, according to SpaceReference.com, a database that compiles information from NASA's Jet Propulsion Laboratory in California and the International Astronomical Union. The rock 2007 FF1 is known as an Apollo-class asteroid, of which there are around 15,000, meaning that its orbit around the sun (which takes 684 days) crosses with Earth's orbit. The asteroid is classified as potentially hazardous because of its size and relatively close orbit to Earth. Full Story: [Live Science]( (3/28)
