If you want to track changes in the Amazon rainforest, see the full expanse of a hurricane or figure out where people need help after a disaster, it's much easier to do with the view from a satellite orbiting a few hundred miles above Earth.
Brazil must protect and restore its dry forests and savannas to achieve its climate goals, new research shows.
Since European colonization, farmers have often viewed dingoes as the enemy, waging war against them to protect their livestock. Farmers felt they had no option but to eradicate dingoes using traps, shooting, poisoned baits (such as 1080) and building a 5,600km long dingo fence, the world's longest.
Trickle-down economics may have more than one meaning in New Mexico. The traditional definition explains that benefits and relief for the wealthy will eventually benefit everyone else. In new UNM Water Resources research, however, the trickle-down economics of irrigation, may be running out of water to drip–literally. The paper is published in the Natural Resources Journal.
When Luiz Inácio Lula da Silva was sworn in for his third term as president of Brazil on January 1, 2023, he invited a diverse group to accompany him as he ascended the ramp to his offices. Among them, two symbolized the giant step that the country was taking toward a more promising ecological future: Chief Raoni Metuktire, a 90-year-old indigenous leader who dedicated his life to the defense of...
Celestial phenomena that change with time such as exploding stars, mysterious objects that suddenly brighten and variable stars are a new frontier in astronomical research, with telescopes that can rapidly survey the sky revealing thousands of these objects.
When assessing the quality of life of people around the world, economists have primarily focused on comparisons between countries, such as European nations vs. African nations vs. the United States. Metrics like per capita income, life expectancy and leisure are often used.
Researchers are developing a 3D-printed insole with integrated sensors that allows the pressure of the sole to be measured in the shoe and thus during any activity. This helps athletes or patients to determine performance and therapy progress.
Scientists revealed the discovery of a relict glacier near Mars' equator. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant...
Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study has found.
It may be better to let a mild fever run its course instead of automatically reaching for medication, new University of Alberta research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down...
Some projections show that widespread adoption of electric vehicles might require costly new power plants to meet peak loads in the evening. A new study shows that placing EV charging stations strategic ways and setting up systems to initiate charging at delayed times could lessen or eliminate the need for new power plants.
New research has established a link between western diets high in fat and sugar and the development of non-alcoholic fatty liver disease, the leading cause of chronic liver disease.
Researchers shed light on the neural stem and progenitor cell (NSPC) microenvironment during development. Neurosphere formation from embryonic mouse forebrain NSPCs was significantly increased under low oxygen conditions, and VEGF-A was identified as a factor released by NSPCs to contribute to this effect. This study demonstrates that NSPCs appear to maintain their own niche and population under...
Proteins are the heavy-lifters of biochemistry. These beefy molecules act as building blocks, receptors, processors, couriers and catalysts. Naturally, scientists have devoted a lot of research to understanding and manipulating proteins.
How mothers and fathers see each other as co-parents of their children plays a key role in how well-adjusted their kids become, a new study suggests.
A new study brings scientists one step closer to answering the question of where Earth's water came from.
Micron-sized 'bow ties,' self-assembled from nanoparticles, form a variety of different curling shapes that can be precisely controlled, a research team has shown.
A new targeted drug has not only sparked remissions in patients with a common form of leukemia but also induced the cancer cells to reveal one of their schemes for resisting the drug, investigators report in a new pair of studies.
Breaking a longstanding impasse in our understanding of olfaction, scientists have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.
A new study represents a first step towards generating highly detailed 3-dimensional maps of lung tumors using genetically engineered mouse models.
A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.
Researchers have found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
