For many NASA scientists, flying aboard a decked-out Douglas DC-8 plane provided them some unique glimpses of Earth: the Moai on Easter Island, Central Park in New York and Mount Vesuvius in Italy.
A wildfire in Canada's major oil-producing region doubled in size as it drew closer to the city of Fort McMurray on Wednesday, but officials were hopeful shifting winds could soon push it away.
A University of Hawaii study examining the health effects of last year's deadly wildfires on Maui found that up to 74% of participants may have difficulty breathing and otherwise have poor respiratory health, and almost half showed signs of compromised lung function.
Scientists have made a breakthrough in significantly improving the sharpness of X-ray imaging and potentially boosting the speeds at which X-ray scans can be processed. This lays the groundwork for both better medical imaging and faster security clearance.
Updated medical guidance on "excited delirium," the controversial term accused of covering up deaths in police custody, including that of George Floyd, is being brought forward before its scheduled date of October 2025, reports The BMJ.
Georgia's saltwater marshes—living where the land meets the ocean—stretch along the state's entire 100-mile coastline. These rich ecosystems are largely dominated by just one plant: grass.
Nutrient-rich blueberries—a common breakfast smoothie ingredient—can also create wine. But does the heat and time required to ferment this mighty berry strip out any of those potential health-promoting compounds? Researchers in ACS Food Science & Technology examine fermentation's effects on the bioactive compounds and antioxidant activity in blueberry wine. The results suggest blueberry wine maintains some of the fruit's nutrients and the team identifies ways to optimize components in this superfood tipple.
Twin shoebox-size climate satellites will soon be studying two of the most remote regions on Earth: the Arctic and Antarctic. The NASA mission will measure the amount of heat the planet emits into space from these polar regions—information that's key to understanding the balance of energy coming into and out of Earth and how that affects the planet's climate.
Nickel monosilicide (NiSi) is widely used to connect transistors in semiconductor circuits. Earlier theoretical calculations had incorrectly predicted that NiSi was not magnetic. As a result, researchers had never fully explored magnetism in NiSi.
A pioneering study published in Oikos has revealed novel insights into how a select group of birds in the Amazon rainforest, known as terrestrial insectivores, is coping with the ever-increasing threats posed by global climate change.
In order for Germany to become climate neutral by 2045, CO2 emissions must first be drastically and permanently reduced. However, CDR measures alone cannot remove the large quantities of CO2 that are emitted in Germany. It is assumed that they can offset only approx. 5–15% of the current emissions.
"Dust clouds" at the bottom of the deep sea, that will be created by deep-sea mining activities, descend at a short distance for the most part. That is shown by Ph.D. research of NIOZ marine geologist Sabine Haalboom, on the bottom of the Pacific Ocean.
Some proteins shift their shape when exposed to different temperatures, revealing previously unknown binding sites for medications, new research has found.
Scenario earthquakes are useful in assessing earthquake hazards along active faults. However, determining the sources of destructive scenario earthquakes, particularly when dealing with heterogeneous stresses, can be challenging.
Computable general equilibrium (CGE) model is an important policy guidance tool for pollution reduction and emission control objectives. An article, published in Energy and Climate Management, introduces the economic module, energy module, macroscopic closure, dynamic mechanism, algorithm and back-of-the-envelope of a CGE. Then, it shows how to extend the CGE to carbon tax and carbon trading market, energy rebound effect, environmental tax and disclosure, and carbon neutral strategies.
Gang Shao's group from Zhengzhou University, China recently investigated the structural evolution of pentagonal polymer-derived SiAlBCN ceramics (PDCs) and outlined PDC-based sensor technology for high-temperature extreme environments. The high-performance temperature sensing materials including high sensitivity, fast response, wide detection range are scarce and needing.
Payment for Ecosystem Services programs (PES) are important tools that governments around the world use to improve water quality, protect forests and wildlife habitat, and sequester carbon. Under these programs, landowners—usually farmers—are paid to use their land in ways that protect or restore the environment, such as replacing row crops with trees or grassy zones adjacent to waterways. Many PES program contracts last 5 to 20 years, but participant drop out rates have consistently risen over the years.
Democratic countries should rely on international law and improve their legal resilience to tackle the grave security threats caused by worsening relations between great powers, new research shows.
