NASA tests mixed reality, scientific know-how and mission operations for exploration

Mixed reality technologies, like virtual reality headsets or augmented reality apps, aren't just for entertainment—they can also help make discoveries on other worlds like the Moon and Mars. By traveling on Earth to extreme environments—from Mars-like lava fields in Hawaii to underwater hydrothermal vents—similar to destinations on other worlds, NASA scientists have tested out technologies and tools to gain insight into how they can be used to make valuable contributions to science.

LED light pollution is a major turnoff to some North American bats

Light pollution, or artificial light at night (ALAN), is a rapidly spreading form of environmental degradation that currently covers about 50% of the United States and 90% of Europe. It can have wide-ranging impacts to nocturnal wildlife by causing changes in foraging behavior, space use, predator-prey interactions, communication and reproduction. New research published this week in the journal Ecology and Evolution demonstrates how disruptive ALAN can be to some bat species of the northeastern U.S.

Building a culture of high-quality data

The era of big data has inundated nearly all scientific fields with torrents of newly available data with the power to stimulate new research and enable inquiry at scales not previously possible. This is particularly true for ecology, where rapid growth in remote sensing, monitoring, and community science initiatives has contributed to a massive surge in the quantity and kinds of environmental data that are available to researchers.

Development of a broadband mid-infrared source for remote sensing

A research team of the National Institutes of Natural Sciences, National Institute for Fusion Science and Akita Prefectural University has successfully demonstrated a broadband mid-infrared (MIR) source with a simple configuration. This light source generates highly-stable broadband MIR beam at 2.5-3.7 μm wavelength range maintaining the brightness owing to its high-beam quality. Such a broadband MIR source facilitates a simplified environmental monitoring system by constructing a MIR fiber-optic sensor, which has the potential for industrial and medical applications.

Tilapia farming: Dwarfism is a response to overcrowding stress

Tilapia living in crowded aquaculture ponds or small freshwater reservoirs adapt so well to these stressful environments that they stop growing and reproduce at a smaller size than their stress-free counterparts.

Architecture of Eolian successions under icehouse and greenhouse conditions

Anthropogenic climate change is one of the foremost scientific and societal challenges. In part, our response to this global challenge requires an enhanced understanding of how the Earth's surface responds to episodes of climatic heating and cooling. As historical records extend back only a few hundred years, we must look back into the ancient rock record to see how the surface of the Earth has responded to shifts between icehouse (presence of ice at the Earth's poles) and greenhouse (no substantial ice at Earth's poles) climates in the past.

Human hiking trails custom built for sauntering grizzlies

In the run up to hibernation, grizzly bears go on a colossal binge, consuming as many calories as possible to get them through the long winter. Yet, little was known about how much energy the massive mammals use as they shamble around their rugged territories. "Moving across the landscape in search of food can be a huge energetic expense for some animals," Carnahan says. Fortunately, the Washington State University Bear Research, Education and Conservation Center (WSU BREC), where Carnahan is based, is home to 11 bears, including four that formerly lived in Yellowstone National Park, so he and Charles Robbins (also at WSU BREC) decided to measure the animals' metabolic rates as they sauntered on the flat, and up and down gradients to find out how much energy they use on a daily basis. The team publishes their discovery that grizzly bears prefer to walk on shallow paths to save energy in Journal of Experimental Biology, explaining why the animals often appear on human hiking trails.
