Poly(lactic acid) with added coconut oil for sustainable food packing
Imagine being able to see the entire Statue of Liberty and a small ant on its nose simultaneously. The drastic difference in size between the two objects would seem to render this task impossible.
A new type of semiconductor may be coming to a high-definition display near you. Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called halide perovskites is capable of emitting multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers.
Inside each and every living cell, there are miniscule structures called membraneless organelles. These tiny powerhouses use chemistry to cue the inner workings of a cell—movement, division and even self-destruction.
(Penn State) In 2016, a team of Penn State and US Department of Energy researchers discovered a cost-effective and environmentally friendly way to extract rare earth elements (REEs) from coal and coal byproducts. Now, through a $1 million grant from DOE's Office of Fossil Energy, this research may be headed one-step closer to commercialization.
Because plants can't get up and run away, they've had to be clever instead. They are the chemists of the living world, producing hundreds of thousands of small molecules that they use as sunscreens, to poison plant eaters, to scent the air, to color flowers, and for much other secret vegetative business.
(Technische Universität Dresden) Xinliang Feng of Center for Advancing Electronics Dresden / Technische Universität Dresden and Klaus Müllen of Max Planck Institute for Polymer Research (MPI-P) in Mainz will be awarded the Hamburg Science Award 2017, which this year is dedicated to the subject of energy efficiency.

(Kumamoto University) Researchers from Kumamoto University in Japan have found that the compound folic acid-conjugated methyl-BETA-cyclodextrin (FA-M-BETA-CyD) has significant antitumor effects on folate receptor-ALPHA-expressing (FR-ALPHA (+)) cancer cells. Show More Summary
Heat and humidity can harm materials. The conditions inside smokestacks often damage materials that could remove carbon dioxide. This is especially true for metal-organic frameworks (MOFs), which remove carbon dioxide under milder conditions. Show More Summary
Depositing one layer of atoms at a time can result in materials that greatly improve fuel cells, batteries and other devices. In this research, scientists precisely added chromium to iron oxides to control the electronic and optical properties. Show More Summary
(Stockholm University) Tetanus toxin is the neurotoxin that causes lockjaw. Many are vaccinated, but tetanus still kills tens of thousands of people per year worldwide. Researchers from the Department of Biochemistry and Biophysics, led by Dr. Pål Stenmark, have now uncovered the poison's structure. For the first time, the way the poison is constructed has been revealed.
(Canadian Medical Association Journal) Health Canada's proposed changes to natural health product regulation are a good step forward, but they need to go further to protect consumers, argues Dr. Matthew Stanbrook in an editorial in CMAJ.
Fast-dissolving nanofiber mats as alternative to eye drops
(Acoustical Society of America) Sound permeates the human experience and gets our attention, sometimes traumatically so. Consider the car horn. It is a widespread practical application of this noise-trauma-alert principle -- and an increasing source of noise pollution worldwide as the global traffic population grows. Show More Summary
(Acoustical Society of America) People who are visually impaired will often use a cane to feel out their surroundings. With training and practice, people can learn to use the pitch, loudness and timbre of echoes from the cane or other sounds to navigate safely through the environment using echolocation.

One of the current challenges in biology is to understand rapidly-changing phenomena. Interestingly, only a small fraction of them is due to proteins acting in isolation, the majority of biological events are regulated by proteins acting together in clusters. Show More Summary
(University of California - Riverside) In the world of electronics, where the quest is always for smaller and faster units with infinite battery life, topological insulators (TI) have tantalizing potential.In a paper published todayShow More Summary
