(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.
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.
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 ...
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.
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 ...
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Palynology professor to help revive vital science
The University of Western Australia, Chevron and Woodside will launch an international search for an expert who can breathe new life into the discipline of palynology in WA.
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 ...
Curiosity Mars rover drills second rock target
(Phys.org) —NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland."
Why are there redheads? Birds might hold the clues
Red coloration—historically seen as costly in vertebrates—historically seen as costly in vertebrates—might represent some physiological benefit after all, according to research published in the journal Physiological an ...
Late Cretaceous Period was likely ice-free
For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University ...
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 ...
