When to Fish: Timing Matters for Fish That Migrate to Reproduce

ASP_Day3-1054.jpg

A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.

Cornell Mathematician's Study of ‘Swarmalators’ Could Direct Future Science

How does the Japanese tree frog figure into the latest work of noted mathematician Steven Strogatz? As it turns out, quite prominently. Cornell researchers used the curious mating ritual of male Japanese tree frogs as inspiration for their exploration of “swarmalators” – their term for systems in which both synchronization and swarming occur together.

Researchers Expect New Fish Passage Will Help Restore Migratory Fish Populations

Strain-Free Epitaxy of Germanium Film on Mica

JAP017741-LIttlejohn-epitaxy-gel.jpg

Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it’s making a comeback. It’s generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals’ forces to grow germanium on mica. They discuss their work in the Journal of Applied Physics.

A Popular Tool to Trace Earth’s Oxygen History Can Give False Positives

If someone cries "Eureka!" because it looks like oxygen appeared in Earth's ancient atmosphere long before the body of evidence indicated, consider this: If it was a chromium isotope system reading that caused the enthusiasm, it might need to be curbed.
