Surface plasmons in graphene have been widely studied in the past decade due to their very appealing properties, such as the strong tunability of its optical properties through electrical gating and the relatively high plasmon lifetime. However, these exceptional properties are limited to lower frequencies ranging from the mid-infrared (mid-IR) to the terahertz (THz) spectral regions.
A field studying something very small is becoming very big: In the last decade, the field of nanoparticle research has exploded. At about one nanometer in size, nanoparticles are 100,000 times smaller than the width a strand of human hair and cannot be seen with the naked eye, but researchers are discovering broad uses for them in fields ranging from bioimaging to energy and the environment.
NASA-NOAA's Suomi NPP satellite passed over the Eastern Pacific Ocean and provided forecasters with a visible image of the waning Tropical Depression 7E. Wind shear and cooler waters were taking their toll on the storm.
INDIANAPOLIS -- The results of the first statewide random sample study in the United States to measure the spread of COVID-19 indicated a general population prevalence of about 2.8 percent in Indiana.
The growing global population and continued economic development will likely require a significant increase in water demand, especially in developing regions. At the same time, climate change is already having global, regional, and local impacts on water availability. Ensuring that the changing supply can meet the continuously growing demand without compromising the sensitive aquatic environments from which it is derived, is clearly a huge challenge that will require strategies and policies informed by science.
(Boston)--Experiences of racism are associated with lower subjective cognitive function (SCF) among African-American women.
Today, we pull the veil back on the secret sex lives of leeches and how researchers at McMaster University and Fisheries and Oceans Canada are using that information to learn about endocrine disrupting chemicals. Leeches, who gained worldwide popularity when making their film debut in the blockbuster "Stand by Me" in 1986, have actually been around much, much longer. They are found on every continent in freshwater habitats where there is little flow. They are popular bait for fishing, and doctors continue to use them in medical treatments.
A comparison of children in Hong Kong, mainland China and the UK has found that British boys' development of key thinking skills, known as 'executive functions', is unusually reliant on their socio-economic status.
The seventh tropical depression of the Eastern Pacific Ocean has formed. NASA's Terra satellite used infrared light to identify the area of strongest storms and coldest cloud top temperatures in Tropical Depression 7E.
Tropical Depression 7E formed in the Eastern Pacific Ocean well to the southwest of Mexico's Baja California Peninsula. However, the storm is expected to be short-lived because it is expected to track over waters too cool to maintain it. Tropical cyclones need sea surface temperatures of at least 26.6 degrees Celsius (80 degrees Fahrenheit) to maintain strength.
Over 360 scientists from 42 countries - led by the University of Göttingen and Westlake University China - call for transition of food production systems to agroecological principles.
Ithaca, NY--A new study from the Cornell Lab of Ornithology highlights specific features of urban green spaces that support the greatest diversity of bird species. The findings were published today in the journal Landscape and Urban Planning.
The study focuses specifically on parks in New York City. It uses observations submitted to the eBird citizen-science database from 2002 through 2019 to estimate the variety of species found on an annual and seasonal basis.

With their tough skins, pointy armor and legendary stamina, cacti are made to defend themselves from whatever nature throws at them.
But large solar energy facilities are one threat that cacti weren't built to withstand, according to a study by the University of California, Davis.
Researchers from KU Leuven, the International Institute of Applied Systems Analysis (IIASA) and RTI International investigated the effects of trade on hunger in the world as a result of climate change. The conclusion is clear: international trade can compensate for regional food shortages and reduce hunger, particularly when protectionist measures and other barriers to trade are eliminated.
