Melting of Arctic ice due to climate change has exposed more sea surface to an atmosphere with higher concentrations of carbon dioxide. Scientists have long suspected this trend would raise CO2 in Arctic Ocean water.

New research by Cornell University and the City College of New York (CCNY), shows that by enforcing a $20 toll for cars and taxis to enter the central business district of Manhattan, traffic congestion could be reduced by up to 40%, public transit ridership could grow by 6% and greenhouse gas emissions could be reduced by 15%.

Out beyond our solar system, visible only as the smallest dot in space with even the most powerful telescopes, other worlds exist. Many of these worlds, astronomers have discovered, may be much larger than Earth and completely covered in water—basically ocean planets with no protruding land masses. What kind of life could develop on such a world? Could a habitat like this even support life?

Smokey the Bear says that only you can prevent wildfires, but what if Smokey had a high-tech backup? In a new study, a team of Michigan State University scientists designed and fabricated a remote forest fire detection and alarm system powered by nothing but the movement of the trees in the wind.

Scientists estimate that the Earth's mantle holds as much water as all the oceans on the planet, but understanding how this water behaves is difficult. Water in the mantle exists under high pressure and at elevated temperatures, extreme conditions that are challenging to recreate in the laboratory.

A research team at Swansea University have developed a new method for fast removal and detection of wastewater pollutants that come from everyday pharmaceuticals like paracetamol, ibuprofen and aspirin, which could help minimise their impact on the environment.

A new nanomaterials microscopy approach called Pulsed Force Kelvin Probe Force Microscopy (PF-KPFM), allows for less than 10 nanometer measurements of work function and surface potential in a single-pass AFM scan. The findings have been published in two related articles in ACS Nano and Angewandte Chemie International Edition.

Eelgrass, a species of seagrass named for its long slippery texture, is one of nature's superheroes. It offers shade and camouflage for young fish, helps anchor shorelines, and provides food and habitat for many marine species.

Fish exposed to very low levels of chemicals commonly found in waterways can pass the impacts on to future generations that were never directly exposed to the chemicals, according to Oregon State University researchers.

Researchers have developed a new plug-and-play device that can add adaptive optics correction to commercial optical microscopes. Adaptive optics can greatly improve the quality of images acquired deep into biological samples, but has, until now, been extremely complex to implement.

Astronomers this month released the largest collection of sharp, detailed images of debris disks around young stars, showcasing the great variety of shapes and sizes of stellar systems during their prime planet-forming years. Surprisingly, nearly all showed evidence of planets.

Barn swallows live almost everywhere on the planet, recognizable by their forked tail and agility in the air. Yet while they share these characteristics, these little birds often look slightly different in each place they live—with some so distinct they're splitting off to become new species.

Heading to the lake this summer? While harmful algal blooms can cause health problems for lake visitors, satellite data can provide early detection of harmful algae, resulting in socioeconomic benefits worth hundreds of thousands of dollars from one harmful algal bloom event, a new study finds. A Resources for the Future (RFF) and NASA VALUABLES Consortium study published in GeoHealth examines the...

The rapid politicization of the COVID-19 pandemic can be seen in messages members of the U.S. Congress sent about the issue on the social media site Twitter, a new analysis found.

A study published in the journal Wetlands documents an invasion happening in the Adirondacks: the black spruce, tamarack, and other boreal species are being overcome by trees normally found in warmer, more temperate forests. Ultimately, researchers from the SUNY College of Environmental Science and Forestry (ESF) predict that these invaders could overtake a variety of northern species, eliminating...

As anti-racism solidarity protests continue around the world, new research suggests mainstream media have a tendency to focus on the violence and spectacle of a protest rather than the substance. That mentality and approach need to change according to Summer Harlow, assistant professor of journalism at the University of Houston Jack J. Valenti School of Communication.

The team of Professor Tobias Bollenbach from the Institute for Biological Physics at the University of Cologne has published a study on a new approach to improving the effectiveness of antibiotics in bacterial infections. The study 'Highly parallel lab evolution reveals that epistasis can curb the evolution of antibiotic resistance,' on ways to controlling antibiotic resistance through targeted...

The crops we grow in the field often form dense canopies with many overlapping leaves, such that young "sun leaves" at the top of the canopy are exposed to full sunlight with older "shade leaves" at the bottom. In order to maximize photosynthesis, resource-use efficiency, and yield, sun leaves typically maximize photosynthetic efficiency at high light, while shade leaves maximize efficiency at low...

Suspended, rotating devices known as "flappers" may be the key to fewer birds flying into power lines, a study by Oregon State University suggests.

As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is likely related to challenges simulating the formation and evolution of clouds.

Scientists at the Centro Nacional de Enfermedades Cardiovasculares (CNIC) have identified the molecular mechanism by which mitochondria, the main source of the cell's energy supply, regulate their function to optimize energy production in order to meet the body's changing needs. The discovery, published in the journal Science Advances, helps to explain how the body regulates its metabolism.

A study analyzing and describing US police-involved fatalities across racial/ethnic groups at the level of individual metropolitan statistical areas publishes June 24, 2020 in the open-access journal PLOS ONE, by Gabriel Schwartz and Jaquelyn Jahn from the Harvard T.H. Chan School of Public Health.

Researchers have been surprised to find that Adélie penguins in Antarctica prefer reduced sea ice conditions, not just a little bit, but a lot. As climate models project rapid reduction of the continent's sea ice over the rest of the century, this iconic polar predator could be a rare global warming winner. Their research findings are published on June 24, 2020 in Science Advances.

German chemical giant Bayer on Wednesday said it has agreed to pay over $10 billion (9 billion euros) in a mass settlement with American plaintiffs who say their cancers were caused by the Roundup weedkiller made by its Monsanto unit.
