(Phys.org) —'Smart' holograms, which are currently being tested to monitor diabetes, and could be used to monitor a wide range of medical and environmental conditions in future, have been developed by researchers.
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Principles of locomotion in confined spaces could help fire ant-inspired robot teams work underground (w/ video)
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much-despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar ...
Mars soil sample delivered for analysis inside rover
(Phys.org)—NASA's Mars rover Curiosity has ingested its first solid sample into an analytical instrument inside the rover, a capability at the core of the two-year mission.
Researchers build most complex synthetic biology circuit yet
Using genes as interchangeable parts, synthetic biologists design cellular circuits that can perform new functions, such as sensing environmental conditions. However, the complexity that can be achieved in ...
From yeast, researchers learn how populations collapse
In the early 1990s, overfishing led to the collapse of one of the most bountiful cod fisheries in the world, off the coast of Newfoundland. Twenty years later, the cod population still has not recovered, dramatically ...
Propensity for longer life span inherited non-genetically over generations, study says
We know that our environment -- what we eat, the toxic compounds we are exposed to -- can positively or negatively impact our life span. But could it also affect the longevity of our descendants, who may live under very different ...
Identical virus, host populations can prevail for centuries
A Woods Hole Oceanographic Institution (WHOI) scientist, analyzing ancient plankton DNA signatures in sediments of the Black Sea, has found for the first time that the same genetic populations of a virus and its algal host ...
When it's cool, female butterflies chase males in sex role reversal
If you want to be surrounded by females on the prowl, it pays to be cool, at least if you are a male butterfly.
Debunking myths about warm-ups, eggs
There are so many things to worry about these days. Wouldn't it be nice to cross something off the list? Turns out you can. Researchers have been busy debunking some common medical myths that have been repeated so many times, ...
Engineer builds instrument to study effects of genes, environment on plant traits
Let's say plant scientists want to develop new lines of corn that will better tolerate long stretches of hot, dry weather.
Seabirds' personalities determine feeding styles
Seabirds have distinct individual personalities that affect where they feed and how likely they are to prosper, a pair of recent studies suggests.
Brown carbon works both sides of the climate equation
There is an atmospheric particle not satisfied with only a single role in the climate. The ambitious culprit? Brown carbon aerosol steps outside the box and acts to both warm and cool the climate. A brown ...
Less toxic metabolites, more chemical product
The first dynamic regulatory system that prevents the build-up of toxic metabolites in engineered microbes has been reported by a team of researchers with the U.S. Department of Energy (DOE)'s Joint BioEnergy ...
