Avatar will not lie... or will it? Scientists investigate how often we change our minds in virtual environments

How confident are you in your judgments and how well can you defend your opinions? Chances are that they will change under the influence of a group of avatars in a virtual environment. Scientists from SWPS University investigated the human tendency to be influenced by the opinions of others, including virtual characters.  We usually conform to the views of others for two reasons. First, we succumb to group pressure and want to gain social acceptance. Second, we lack sufficient knowledge and perceive the group as a source of a better interpretation of the current situation, describes Dr. Konrad Bocian from the Institute of Psychology at SWPS University.  So far, only a few studies ...

Genes identified that allow bacteria to thrive despite toxic heavy metal in soil

VANCOUVER, Wash. -- Some soil bacteria can acquire sets of genes that enable them to pump the heavy metal nickel out of their systems, a study has found. This enables the bacteria to not only thrive in otherwise toxic soils but help plants grow there as well. A Washington State University-led research team pinpointed a set of genes in wild soil bacteria that allows them to do this in serpentine soils which have naturally high concentrations of toxic nickel. The genetic discovery, detailed in the journal Proceedings of the National Academies ...

Artificial streams reveal how drought shapes California’s alpine ecosystems

Berkeley — A network of artificial streams is teaching scientists how California’s mountain waterways — and the ecosystems that depend on them — may be impacted by a warmer, drier climate. Over the next century, climate change is projected to bring less snowfall to the Sierra Nevada. Smaller snowpacks, paired with warmer conditions, will shift the annual snowmelt earlier into the year, leaving less water to feed streams and rivers during the hot summer months. By 2100, mountain streams are predicted to reach their annual base, or “low-flow,” conditions an average of six ...

Harnessing hydrogen at life’s origin

A new report uncovers how hydrogen gas, the energy of the future, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2. Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is good fuel for as long as there has been life on Earth. Hydrogen is ancient energy. The very first cells on Earth lived from H2 produced in hydrothermal vents, using the reaction of H2 with CO2 to make the molecules of ...
