Scientists are digitizing the wealth of data attached to herbarium specimens and using those data to address questions ranging from species identification to global climate change. This special issue explores methods, challenges, and applications of these collections data, with articles addressing topics including globally unique identifiers, deep learning and computer recognition, and citizen science initiatives.
Regardless of political affiliation, people are more likely to believe facts about climate change when they come from Republicans speaking against what has become a partisan interest in this country, says a new UConn study.
Coal mining, under current US regulations, has significantly reduced the abundance and variety of fish, invertebrates, salamanders, and other aquatic life in streams, according to a new study from the University of Tennessee, Knoxville.
An international research team has proposed a way to increase the efficiency of wireless power transfer over long distances and tested it with numerical simulations and experiments. To achieve this, they beamed power between two antennas, one of which was excited with a back-propagating signal of specific amplitude and phase. The new development will improve wireless power transmission. This study also offers new approaches to wireless communication, where external conditions can change unpredictably.
The Collaborative Laboratories for Environmental Analysis and Remediation at the University of Texas at Arlington has expanded its partnership with oil field equipment supplier Challenger Water Solutions to develop water recycling technologies that will transform waste from unconventional oil and gas development into reusable water.
As summertime draws near, some people around the US will face annual water usage restrictions as water supplies become strained. But for those who live in arid climates year-round, water shortages are a constant concern. In these areas, residents must capitalize on even the smallest bit of moisture in the air. Now researchers report in ACS Applied Materials & Interfaces that they have developed a type of 'harp' to harvest fresh water from fog.
The first step after buildings collapse from an earthquake, bombing or other disaster is to rescue people who could be trapped in the rubble. But finding entrapped humans among the ruins can be challenging. Scientists now report in the ACS journal Analytical Chemistry the development of an inexpensive, selective sensor that is light and portable enough for first responders to hold in their hands or for drones to carry on a search for survivors.
The flight routes of passenger aircraft are generally well established. In practice, unforeseen factors, mainly related to the weather, often force pilots to cover more kilometers than anticipated. A Polish-Colombian team of scientists and engineers, inspired by the behavior of insects and birds, has developed software that allows real-time rational modification of flight routes. As a result, it was possible to achieve measurable savings, both financial and with regard to environmental protection.
A new study found the Pacific Walker circulation, one of the most important circulation systems in the tropics, shows a significant interannual weakening after strong tropical volcanic eruptions.
Surface air temperature (SAT) anomalies have pronounced impacts on agriculture, socioeconomic development, and people's daily lives. A question is whether the Eurasian atmospheric circulation anomalies can persist from winter to the following spring. Using observational data and atmospheric model simulation, scientists from the Institute of Atmospheric Physics of the Chinese Academy of Sciences reported that the dominant mode of winter Eurasian 500-hPa geopotential height anomalies could maintain to the following spring.
