Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual...

A study of more than 1,000 demographically representative participants found that about 22 percent of Americans self-identify as anti-vaxxers, and tend to embrace the label as a form of social identity.

If you're wearing gold jewelry right now, there's a good chance it came from an illegal mining operation in the tropics and surfaced only after some rainforest was sacrificed, according to a team of University of Wisconsin-Madison researchers and alumni who studied regulatory efforts to curb some of these environmentally damaging activities in the Amazon.

Tiny algae in Earth's oceans and lakes take in sunlight and carbon dioxide and turn them into sugars that sustain the rest of the aquatic food web, gobbling up about as much carbon as all the world's trees and plants combined.

Though it might seem inanimate, the soil under our feet is very much alive. It's filled with countless microorganisms actively breaking down organic matter, like fallen leaves and plants, and performing a host of other functions that maintain the natural balance of carbon and nutrients stored in the ground beneath us.

There's a lot of interest right now in how different microbiomes—like the one made up of all the bacteria in our guts—could be harnessed to boost human health and cure disease. But Daniel Segrè has set his sights on a much more ambitious vision for how the microbiome could be manipulated for good: "To help sustain our planet, not just our own health."

A new study shows that substantial amounts of carbon dioxide were released during the last millennium because of crop cultivation on peatlands in the Northern Hemisphere.

The world is one step closer to ultimately secure conference calls, thanks to a collaboration between Quantum Communications Hub researchers and their German colleagues, enabling a quantum-secure conversation to take place between four parties simultaneously.

Accurate soft tissue measurements are critical when making reconstructions of human ancestors, a new study from the University of Adelaide and Arizona State University has found.

A new study of monsoon rainfall on the Indian subcontinent over the past million years provides vital clues about how the monsoons will respond to future climate change.

With the massive proliferation of data-heavy services, including high-resolution video streaming and conferencing, cloud services infrastructure growth in 2021 is expected to reach a 27% CAGR. Consequently, while 400 gigabit ethernet (GbE) is currently enjoying widespread deployment, 800 GbE is poised to rapidly follow to address these bandwidth demands.

The COVID-19 pandemic forced instructors to adapt their courses for online learning. Laboratory courses were particularly difficult due to lack of access to specialized equipment for remote learners. To overcome this challenge, researchers from the University of Illinois Urbana-Champaign designed a laboratory exercise to teach students how to use micropipettes, through remote learning, using...

As meat-eating continues to increase around the world, food scientists are focusing on ways to create healthier, better-tasting and more sustainable plant-based protein products that mimic meat, fish, milk, cheese and eggs.

As India continues to be ravaged by the pandemic, a Swansea University academic is investigating how green tea could give rise to a drug capable of tackling COVID-19.

Deforestation in the Brazilian Amazon reached a record for the month of May this year, the space research institute INPE said.

How plants cope with stress factors has already been broadly researched. Yet what happens when a plant is confronted with two stressors simultaneously? A research team working with Simon Haberstroh and Prof. Dr. Christiane Werner of the Chair of Ecosystem Physiology at the Institute of Forest Sciences and Natural Resources (UNR) of the University of Freiburg is investigating this. Together with...

Scientists at Leipzig University, in collaboration with colleagues from Germany and England, have succeeded in reversibly slowing down cellular processes. A team of biophysicists led by Professor Josef Alfons Käs and Dr Jörg Schnauß were able to show in experiments that cells can be transferred into slow motion without changing the temperature.

Graphene may be among the most exciting scientific discoveries of the last century. While it is strikingly familiar to us—graphene is considered an allotrope of carbon, meaning that it essentially the same substance as graphite but in a different atomic structure—graphene also opened up a new world of possibilities for designing and building new technologies.

Marine forecasters face the challenge of predicting a very complex and constantly changing marine environment by applying ocean science, knowledge and technological skills to produce predictions of the state of the ocean.

Since the era of meteorological satellites began in the 1950s, continuous remote sensing instrument improvements have elevated Earth science and have significantly increased available atmospheric observations. Likewise, scientists have made considerable advancements in understanding Earth's atmosphere, climate, and environment.

Extreme risk protection orders, also known as gun violence restraining orders (GVROs) or "red flag" orders, exist in 19 states and the District of Columbia.

The cost of offsetting corporate carbon emissions needs to increase ten-fold to drive meaningful climate action, says a landmark report by Trove Research and UCL.

Certain cyanobacteria can change the absorbing light colors for photosynthesis using a green- and red-light sensing photosensor protein. A Japanese research group elucidated the molecular structure of RcaE, a representative member of the photosensors. They revealed the unique conformation of the bilin chromophore and the unique protein structure that potentially functions as a proton transfer...

The melodic and diverse songs of birds frequently inspire pop songs and poems, and have been for centuries, all the way back to Shakespeare's "Romeo and Juliet" or "The Nightingale" by H.C. Andersen.
