Ban on microbeads offers best chance to protect oceans and aquatic species


An outright ban on the common use of plastic "microbeads" from products that enter wastewater is the best way to protect water quality, wildlife, and resources used by people, a group of conservation scientists suggest in a new analysis. These microbeads are one part of the microplastic problem ...


Environmentally friendly lignin nanoparticle 'greens' silver nanobullet to battle bacteria


North Carolina State University researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ...


Gender inequality in scientific professions

Global survey results


Recent global survey reveals that female scientists are more likely to be dissatisfied with salary/benefits, job availability, gender barriers, and how they feel valued as scientists than their male colleagues (within a 5% range). The Science Advisory Board’s “Global Science 2015” survey sought ...

Novel technique enables air-stable water droplet networks


A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research and harvesting water from fog. Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a method to create ...

Research combines graphene and painkiller receptor


Almost every biological process involves sensing the presence of a certain chemical. Finely tuned over millions of years of evolution, the body’s different receptors are shaped to accept certain target chemicals. When they bind, the receptors tell their host cells to produce nerve impulses, ...

New microscope sees what others can't


Microscopes don't exactly lie, but their limitations affect the truths they can tell. For example, scanning electron microscopes (SEMs) simply can't see materials that don't conduct electricity very well, and their high energies can actually damage some types of samples. In an effort to extract a ...

Simple microfluidic devices now have valves


Researchers at the National Institute of Standards and Technology (NIST) have added yet another innovation—miniature valves—to their ever-growing collection of inexpensive, easy-to-manufacture and highly efficient microfluidic devices made from plastic films and double-sided tape. Traditionally, ...


Ancient whodunit may be solved: The microbes did it!

Methane-producing microbes may be responsible for the largest mass extinction in Earth's history


Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out — by far the largest of this planet's five known mass extinctions. But pinpointing the culprit has been ...

Nanotube coating helps shrink mass spectrometers


Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. Researchers found that when paper used to collect a sample was coated with carbon nanotubes, ...


Cheaper, greener way to make new drugs


This alternative approach to creating artificial organic molecules, called bioretrosynthesis, was first proposed four years ago by Brian Bachmann, associate professor of chemistry at Vanderbilt University. Now Bachmann and a team of collaborators report that they have succeeded in using the ...
