Two dozen volunteers bravely exposed their arms to jellyfish tentacles as part of a new Stanford University School of Medicine study to test a topical, over-the-counter cream designed to protect against stinging nettles. Fortunately for the volunteers, the cream appeared to be relatively effective.
"It didnt completely inhibit the stings, but it came pretty darn close," reported Alexa Kimball, MD, MPH, an assistant professor of dermatology who directed the study. The study appears in the June issue of the journal Wilderness and Environmental Medicine.
The Stanford researchers borrowed sea nettles from the Monterey Bay Aquarium to do the testing on volunteers in a research clinic at Stanford Hospital. These nettles are known to sting swimmers, surfers and boaters worldwide, including along the Chesapeake Bay and the coastlines of Florida and California. Their stings cause a burning sensation, as well as swelling, pain and occasional blisters.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
