Researchers evaluate the effects of warm waters on little fish
Warm Caribbean waters may provide a toasty growing area for larval fish, but thats not enough to ensure a flourishing fish population. Thats the conclusion of research published in this months edition of Marine Ecology Progress Series by Dr. Su Sponaugle and colleagues from the University of Miami Rosenstiel School. The scientists studied the petite, yet eye-catching blue-headed wrasse in the upper Florida Keys to monitor larval settlement success.
“The key to any larval reef fishs survival is to find food, avoid predation, and get to a reef to settle,” Sponaugle said. Fish larvae remain at sea for several weeks before returning to the reef to settle and join adult populations. What goes on during this time in the plankton is largely unknown. “What we found is that warm summer waters here are conducive to rapid larval growth, but other factors sometimes interfere, leading to highly variable settlement rates.”

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.
An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
