Field study shows glassfrog embryos hatch early if not well cared for by parent
(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.
Researchers call for changes in 50 year-old drinking water standards
Changes in drinking water quality in the 21st Century are coming from a myriad of circumstances, and not all are for the best. Top contenders for why water-drinking quality might become suspect to the average ...
Chemists develop 'nanoreactor' for discovering new chemical reactions
(Phys.org) —In 1952, the famous Urey-Miller experiment mixed together chemicals that were present early in Earth's history, then approximately replicated the environmental conditions on the planet at that ...
Curiosity Mars rover finds mineral match
(Phys.org) —Reddish rock powder from the first hole drilled into a Martian mountain by NASA's Curiosity rover has yielded the mission's first confirmation of a mineral mapped from orbit.
Mars rover Opportunity's vista includes long tracks
From a ridgeline viewpoint, NASA's Mars Exploration Rover Opportunity recently recorded a scene looking back over its own tracks made from nearly half a mile (more than 700 meters) of southbound driving.
