Big Waves (start time 4:39):  When does one plus one not equal two? When waves behave non-linearly, according to CU researchers Mark Ablowitz and Douglas Baldwin.  The two have been researching how multiple water waves can add together to form a wave with a height much greater than twice the height of either wave. The mathematicians refer to these as X and Y waves, which sounds mathematical but actually just refers to the shape of the wave front as seen looking down on the wave from above. Rather than being rare, these waves are readily observable and may be the reason that some tsunamis are much larger than anticipated.  We spoke yesterday with the pair to find out more about these interesting waves. Omega 3 Fatty Acids (start time 14:49): It’s widely accepted that Omega 3 supplements are good for many things, especially your heart, and that fish oil is high in Omega 3. But earlier this month, Greek researchers made a splash with a meta-analysis that concluded that fish oil supplements do not help your he
