Bizarre attractive force found in mayonnaise
Source: RiceU Posted: 3/30/04
Scientists at Rice University have discovered that a little-understood tensile force, which was previously thought to be an oddity found only in the types of plastics used to make bulletproof vests, occurs in everyday emulsions like mayonnaise and salad dressing.

Mars Express confirms methane in the Martian atmosphere
Source: ESA Posted: 3/30/04
During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as they may be, scientists are thinking about the next steps to take in order to understand more.
