Glacial retreat in cold, high-altitude ecosystems exposes environments that are extremely sensitive to phosphorus input, new University of Colorado Boulder-led research shows. The finding upends previous ecological assumptions, helps scientists understand plant and microbe responses to climate change and could expand scientists' understanding of the limits to life on Earth.

Organic light-emitting diodes (OLEDs) truly have matured enough to allow for first commercial products in form of small and large displays. In order to compete in further markets and even open new possibilities (automotive lighting, head-mounted-displays, micro displays, etc.), OLEDs need to see further improvements in device lifetime while operating at their best possible efficiency. Currently, intrinsic performance progress is solely driven by material development.

Indigenous communities are rejecting non-indigenous energy projects in favour of community-led sustainable energy infrastructure.

The switch has led to some improvements in economic and social development as well as capacity-building for self-governance, according to a study from the University of Waterloo.

ITHACA, NY - The way people get around, particularly in big cities like New York, is changing rapidly, but a fundamental problem remains unsolved: how to best size and operate a fleet of vehicles, especially traditional taxis and particularly given taxi riders' attitudes toward sharing.

Toxic substances, nutrient shortage, viral infection, heat and many other events trigger stress responses in cells. In such cases, the affected cells launch a programme which tries to protect them against stress-related damages. They usually ramp down the production of endogenous proteins to save resources which they later need to repair cell damages or to survive under the stress conditions for some time.

Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, the HAL QCD Collaboration, made up of scientists from the RIKEN Nishina Center for Accelerator-based Science and the RIKEN Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) program, together with colleagues from a number of universities, have predicted a new type of "dibaryon"--a particle that contains six quarks instead of the usual three.

Boldness correlates with the mating success, but not body size or sex, of yellow-spotted monitor lizards roaming the remote Oombulgurri floodplains of tropical Western Australia, ecologists report in the Ecological Society of America's open access journal Ecosphere. But boldness has a cost: bold individuals expose themselves to much higher risk of being eaten by predators during the dangerous wet season.

The world of reptiles may well include creatures that are more spectacular than the Gehyra variegata, but nevertheless, this small nocturnal gecko has managed to make a couple of fascinating new contributions to the discussion about the ecological consequences of climate change.

A new study published in the Taylor & Francis journal Temperature compares how different types of cars warm up on hot days when exposed to different amounts of shade and sunlight for different periods of time. The research team took into account how these differences would affect the body temperature of a hypothetical 2-year-old child left in a vehicle on a hot day.

A lot can happen at 160 degrees Fahrenheit: Eggs fry, salmonella bacteria dies, and human skin will suffer third-degree burns. If a car is parked in the sun on a hot summer day, its dashboard can hit 160 degrees in about an hour. One hour is also about how long it can take for a young child trapped in a car to suffer heat injury or even die from hyperthermia.
