(Salk Institute) Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal axons--threadlike projections--to successfully reach their destinations in the body. Now, Salk Institute researchers discover how neurons navigate a tricky cellular environment by listening for directions, while simultaneously filtering out inappropriate instructions to avoid getting lost.

(University of Illinois College of Agricultural, Consumer and Environmental Sciences) Weeds often emerge at the same time as vulnerable crop seedlings and sneak between plants as crops grow. How do farmers kill them without harming the crops themselves? In a new University of Illinois study, researchers identify genes and metabolic pathways responsible for safener efficacy in grain sorghum.

(University of California - Los Angeles) At the center of our galaxy, where an enormous black hole blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and explode. astronomers have discovered two exhaust channels -- dubbed the 'galactic center chimneys' -- that appear to funnel matter and energy away from the cosmic fireworks.

(AKSON Russian Science Communication Association) Magnetic stir bars are regarded as reusable consumables, and in many labs they last for months. This study shows that in a regular catalysis lab almost all magnetic stir bars become permanently contaminated with metal nanoparticles. Regular cleaning procedures do not remove such contamination completely. Indeed, subsequent release of metal traces in the next reactions is unacceptable even in small quantitates. The results of this study are published in ACS Catalysis.

(Chalmers University of Technology) Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

(The Protein Society) The Protein Society, the premier international society dedicated to supporting protein research, announces the winners of the 2019 Protein Society Awards, which will be conferred at its 33rd Annual Symposium (June 30 - July 3, in Seattle Washington). Plenary talks from the award recipients are scheduled throughout the 3.5-day event*.

(University of Illinois at Chicago) Researchers from the University of Illinois at Chicago College of Engineering describe for the first time several unique properties of materials known as phase-switching liquids, or PSLs, that hold promise as next-generation anti-icing materials. PSLs can delay ice and frost formation up to 300 times longer than state-of-the-art coatings being developed in laboratories.

(European Association of Urology) For the first time, scientists have identified compounds found in coffee which may inhibit the growth of prostate cancer. This is a pilot study, carried out on drug-resistant cancer cells in cell culture and in a mouse model; it has not yet been tested in humans. This work is presented at the European Association of Urology congress in Barcelona, after publication in the peer-reviewed journal The Prostate* (this press release contains additional material).
