UC Santa Barbara researchers continue to push the boundaries of LED design a little further with a new method that could pave the way toward more efficient and versatile LED display and lighting technology.

Techniques used to detect fingermarks on traditional cotton banknotes are not effective on Scottish banks' new polymer notes and different methods are required, according to a study by University of Strathclyde researchers.

Translocation is an important management tool used for nearly 100 years to increase bighorn sheep population numbers in Wyoming and to restore herds to suitable habitat throughout their historical range. Yet, translocation also can alter the underlying genetic diversity of managed wildlife species in both beneficial and detrimental ways.

Integrating radiocarbon dating and microarchaeology techniques has enabled more precise dating of the ancient Wilson's Arch monument at Jerusalem's Temple Mount, according to a study published June 3, 2020 in the open-access journal PLOS ONE by Johanna Regev from the Weizmann Institute of Science, Israel, and colleagues.

Dominance rank among female mountain gorillas is not related to body size but does increase their reproductive output according to research publishing June 3, 2020 in the open-access journal PLOS ONE, led by Edward Wright from the Max Planck Institute for Evolutionary Anthropology, Germany, and colleagues.

Some Alaskan soils harbor elevated concentrations of heavy metals that can harm human health, but critical data gaps impede understanding of exposure risks for Arctic communities. Clarice Perryman of the University of New Hampshire, Durham, and colleagues present these findings in the open-access journal PLOS ONE on June 3, 2020.

People want to help each other, even when it costs them something, and even when the motivations to help don't always align, a new study suggests.

Almost any grocery store is filled with products made from corn, also known as maize, in every aisle: fresh corn, canned corn, corn cereal, taco shells, tortilla chips, popcorn, corn sweeteners in hundreds of products, corn fillers in pet food, in soaps and cosmetics, and the list goes on.

Researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have discovered a system that provides cells with information about their position within developing organs. This system, studied in developing limbs, tells cells what anatomical structure they need to form within the organ. The article, published today in Science Advances, shows that malfunctioning of this system causes...

Throughout Earth's long history, volcanic super-eruptions have been some of the most extreme events ever to affect our planet's rugged surface. Surprisingly, even though these explosions eject enormous volumes of material—at least 1,000 times more than the 1980 eruption of Mount St. Helens—and have the potential to alter the planet's climate, relatively few have been documented in the geologic...

A Northern Arizona University professor co-authored a paper on the importance of springs in a drying climate that is in the inaugural climate change refugia special edition of Frontiers in Ecology and the Environment.

Astronomers announced the discovery of a ghostly, almost perfectly circular, arc of ultraviolet emission centered on the handle of the Big Dipper and stretching 30 degrees across the Northern sky. If the arc were extended, it would completely encircle the Big Dipper with a diameter of 60 degrees.

Scientists from IFJ PAN in cooperation with researchers from the Nara Women's University (Japan) and the Jagiellonian University (Poland) took another important step towards building a functional quantum computer. Using material containing terbium ions and dedicated experimental tools, they performed a detailed analysis of dynamic magnetic properties in individual molecular magnets concerning...

One-third of American families have lost income since the beginning of shutdown triggered by the coronavirus pandemic, with such losses striking families from all economic groups, according to a new nationally representative survey by the RAND Corporation.

Satellite data of Tropical Cyclone Nisarga's cloud top temperatures revealed that the storm had strengthened before it began making landfall in west central India.

Volcanic eruptions and human-caused changes to the atmosphere strongly influence the rate at which the ocean absorbs carbon dioxide, says a new study. The ocean is so sensitive to changes such as declining greenhouse gas emissions that it immediately responds by taking up less carbon dioxide.

Van Andel Institute scientists have for the first time described the near-atomic level structure of a molecular pathway that plays critical roles in human development, blood pressure regulation, inflammation and cell death. The findings were published today in the journal Nature.

High rivers and high levels of nitrogen and phosphorus from farm and urban runoff mean a larger than average oxygen-starved record from 2017 is nearly 8,800 square miles (22,800 square kilometers).

Air pollution has become a fact of modern life, with a majority of the global population facing chronic exposure. Although the impact of inhaling polluted air on the lungs is well known, scientists are just now beginning to understand how it affects the brain. A new article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, details how researchers are...

The third tropical cyclone of the Atlantic Ocean basin has been generating large amounts of rainfall over Mexico's Yucatan and parts of Central America. Using satellite data, NASA analyzed that heavy rainfall and provided forecasters with valuable cloud top temperature data to help assess the strength of the storm.

Van Andel Institute scientists have revealed the first known atomic structure of a "molecular machine" responsible for installing critical signaling proteins into cellular membranes.

Scientists have tried to develop synthetic red blood cells that mimic the favorable properties of natural ones, such as flexibility, oxygen transport and long circulation times. But so far, most artificial red blood cells have had one or a few, but not all, key features of the natural versions. Now, researchers reporting in ACS Nano have made synthetic red blood cells that have all of the cells'...

Scientists have long debated which genetic information carrier—DNA or RNA—started life on Earth, but a new study suggests life could have begun with a bit of both. The research, led by scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB), in Cambridge, shows for the first time how some of the building blocks of both DNA and RNA could have spontaneously...

Driven by the ever-increasing desires of the consumer market for smaller, lighter and smarter devices, the size of consumer electronics such as smartphones, tablets and laptops, have been continually shrinking while becoming more powerful in terms of performance over the years.
