Climate change could deliver more silt, sand and pollution to the San Francisco Bay-Delta, along with a mixed bag of other potential consequences and benefits, according to a new study in the AGU journal Water Resources Research, which publishes research articles and commentaries providing a broad understanding of the role of water in Earth's natural systems.
Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3-D displays, virtual reality and even self-driving vehicles.
Typhoon Maysak was moving north through the East China Sea early on Sept. 2 when NASA-NOAA's Suomi NPP satellite passed overhead and captured a visible image of the storm approaching landfall in South Korea.
Seaport footprints will need to expand by up to 3,689 square kilometers (1,424 square miles) worldwide in the next three decades to cope with the combination of sea-level rise and rising demand, according to a new study published in Earth's Future, a peer-reviewed scientific journal focusing on climate change and future sustainability.
When NASA's Terra satellite passed over the Northwestern Pacific Ocean, it gathered water vapor data on recently developed Typhoon Haishen and found powerful storms in two locations.
You might need a microscope to witness the next agricultural revolution. New research, published in the journal Science Advances, demonstrates how microfluidic technologies can be used to identify, isolate and propagate specific single photosynthetically active cells for fundamental industry applications and improved ecosystem understanding.
Every four years, U.S. presidential campaigns collectively spend billions of dollars flooding TV screens across the country with political ads. But a new study co-authored by Yale political scientist Alexander Coppock shows that, regardless of content, context, or audience, those pricey commercials do little to persuade voters.
To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the Moon, according to a study published today in Science Advances led by Shuai Li, assistant researcher at the Hawai'i Institute of Geophysics and Planetology (HIGP) in the UH Mānoa School of Ocean and Earth Science and Technology (SOEST).
Grade 3 students who watch more than two hours of TV daily or spend more than one hour a day on a computer experience a decline in academic results two years later, a new study has found.
Asphalt is a near-ubiquitous substance—it's found in roads, on roofs and in driveways—but its chemical emissions rarely figure into urban air quality management plans.
The world is one step closer to having a totally secure internet and an answer to the growing threat of cyber-attacks, thanks to a team of international scientists who have created a unique prototype which could transform how we communicate online.
Through the analysis of vegetation from a Bering Sea island, researchers have determined that the extent of sea ice in the region is lower than it's been for thousands of years.
Purdue University researchers have passed another significant milestone as they work to take a new two-dimensional nanomaterial to market for use in nanoelectronics, quantum devices and infrared technology used in national defense tools and biochemical sensors.
What if impact craters, long seen as harbingers of death, turned out to be the cradle of life?
Like humans, bacteria live together in communities, sometimes lending a hand—or in the case of bacteria, a metabolite or two—to help their neighbors thrive. Understanding how bacteria interact is critical to solving growing problems such as antibiotic resistance, in which infectious bacteria form defenses to thwart the medicines used to fight them.
House sparrows can be found on nearly every continent including North America, South America, Africa and Australia, where they are not native but an invasive species. New research into these highly social songbirds reveals that they can learn from each other and adapt their behavior.
The storm was a potential tropical depression on Sept. 1, but by Sept. 2, the area of low pressure in the Caribbean Sea strengthened into a tropical storm and was named Nana.
Sudden death syndrome (SDS) is one of the most destructive diseases of soybean, with losses of nearly 1.7 million metric tons in 2014. The disease is especially severe in the Midwest and North-Central regions, where conditions of high soil humidity and cold weather help the disease grow. SDS is difficult to control as current management practices, which include using fungicide seed treatments and...
As introduced species spread around the world, the complex networks of interactions between plants and animals within ecosystems are becoming increasingly similar, a process likely to reinforce globalization's imprint on nature and increase risks of sweeping ecological disruption.
Black holes can expel a thousand times more matter than they capture. The mechanism that governs both ejection and capture is the accretion disk, a vast mass of gas and dust spiraling around the black hole at extremely high speeds. The disk is hot and emits light as well as other forms of electromagnetic radiation. Part of the orbiting matter is pulled toward the center and disappears behind the...
Tropical Depression 15 strengthened into a tropical storm late on Sept. 1 and was renamed Omar. Visible imagery from NASA-NOAA's Suomi NPP satellite was compiled into an animation that showed the system's formation and strengthening. NASA's Terra satellite also provided temperature data on Omar that revealed wind shear was affecting the storm.
Theoretical frameworks of chiroptical properties of electromagnetic materials and fields are reviewed. Based on these fundamentals, chiroptical systems can be understood, and complicated chiroptical phenomena can be described.
Our gut microbiota can crucially influence our behavior and neurodevelopment. New research from the Ethology Department at the Faculty of Science at Eötvös Loránd University indicates that dogs' aging mechanism and memory performance are also linked to their gut microbiome composition. According to the study, dogs and humans may have similar mechanisms in cognitive aging.
Radiocarbon dating of five large and potentially old sessile oaks from Aspromonte National Parks has revealed a long lifespan ranging from 934 ± 65 to 570 ± 45 years. For a long time, majestic oaks have been considered a symbol of longevity, and this study proves that a millennium age horizon is attainable longevity in angiosperms growing at high-elevation belt in Mediterranean mountains of...
