Key immune substance linked to asthma, Stanford study finds

A Stanford study has linked gamma-interferon, a key immune molecule, to the severity of asthma. High levels of gamma-interferon in children's blood may protect against asthma development, but severe asthmatics' lungs often have high concentrations.

Extending the vase life of cut flowers: Pre-treatments and preservatives studied

A comprehensive 8-year study found that holding preservatives increased the vase life of 53 cultivars, while hydrating preservatives reduced it in 18 species. The researchers concluded that a universal recommendation for use of holding preservatives cannot be made due to its negative effect on some cultivars.

Integral challenges physics beyond Einstein

Integral's observations show that quantum 'graininess' must be at much smaller scales than previously predicted, contradicting Einstein's General Theory of Relativity. The results limit the size of these grains to 10^-48 m or smaller, ruling out some string theories and quantum loop gravity theories.
