New vegetation photosynthetic phenology dataset generated in northern terrestrial ecosystems
Vegetation phenology, the cycle sequence of the vital activities, is a highly sensitive indicator of the climate impacts on terrestrial ecosystems. Most recent studies focus on the structural changes in plants, such as using the growth process of lea.....»»
Musk’s new Grok upgrade allows X users to create largely uncensored AI images
With Grok's new AI image generator, X users put Musk's "freedom of speech" to the test. Enlarge / An AI-generated image of Donald Trump and catgirls created with Grok, which uses the Flux image synthesis model. (credit: BEAST / X.....»»
Early improvement of sandy habitat led to origin of agriculture in the farming-pastoral zone of northern China: Study
The beginning of agriculture is one of the most significant events in human history. The origin and spread of agriculture accelerated the development of human society and economy and fundamentally altered humans' role in the Earth's ecosystem. This a.....»»
Shipping emissions regulations enacted in 2020 improved air quality but accelerated warming, study finds
Last year marked Earth's warmest year on record. A new study finds that some of 2023's record warmth, nearly 20%, likely came as a result of reduced sulfur emissions from the shipping industry. Much of this warming is concentrated over the northern h.....»»
Earth hit by "severe" solar storm
The Earth was hit Monday by an intense solar storm that could bring the northern lights to night skies further south than normal, a US agency announced......»»
Faint auroras may be visible in Northern Hemisphere skies after weekend solar storms
Solar storms persisting from the weekend may produce faint colorful auroras across the Northern Hemisphere, with little disruption to power and communications, space forecasters said Monday......»»
Forensic science cracks the "unsolvable" case of a World War I soldier"s identity, enabling his re-burial
In the early hours of July 18, 1918, the Franco-American counter-offensive against German positions began at Aisne-Marne in northern France. The first division of the American Expeditionary Force (AEF) drove the German forces back, but not without si.....»»
Liked to death? The social media race for nature photos can trash ecosystems—or trigger rapid extinction
Have you ever liked or shared a social media post about nature? It could have been a photo of a rare orchid or an unusual bird. Or you might share a stunning photo of an "undiscovered" natural place......»»
First map of vegetation across Antarctica reveals a battle for the continent"s changing landscape
A tiny seed is stuck between loose gravel and coarse sand. There is nothing else alive around it. All it can see is a wall of ice reaching 20 meters up into the sky. It is cold. Survival is hard around here. In winter, it is dark even during the day......»»
How feeding birds may be polluting local environments
New research led by an NAU alumnus shows that backyard bird feeders, although put out with the best of intentions, is changing the chemistry of local ecosystems, including introducing a potentially harmful amount of phosphorus into the environment......»»
The earliest traces of life on Earth—researchers explore carbon in 3.9-billion-year-old Canadian rocks
The isotopic composition of carbon in iron formations from the Saglek-Hebron Complex in Nunatsiavut (northern Labrador) has been seen as evidence of the earliest traces of life on Earth. But a new study by the University of Ottawa, Carleton Universit.....»»
Sea of opportunity: Protecting mangroves, seagrass could boost Indonesia"s new climate targets
Indonesia has signaled it could include blue carbon ecosystems—carbon-rich coastal and marine areas, like mangroves and seagrass—in its new climate targets. This shift follows years of relying heavily on the forestry and land sectors as well as t.....»»
High nitrogen input promotes the redistribution of new organic carbon to deeper soil layers
Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems. Most current research on soil organic carbon (SOC) dynamics in relation to nitrogen input has focused predominantly on the surface soil layers. How.....»»
Australian science magazine slammed over AI-generated articles
One of Australia's leading science magazines drew fire Thursday after publishing AI-generated articles that experts said were incorrect or oversimplified......»»

Plants show surprising diversity in arid landscape: How livestock grazing impacts drylands
Understanding how plants cope with climatic extremes and grazing pressure is important for reliable predictions about future biodiversity and the functioning of dryland ecosystems......»»
Middle-aged radicalization: Why are so many of Britain"s rioters in their 40s and 50s?
Look closely at the pictures of the violent unrest that has spread across England and Northern Ireland and you will notice something that is not being spoken about. The rioters seen fighting, attacking police and setting fire to buildings are often m.....»»
Planning for climate resilience in California"s freshwater ecosystems
California's unique geomorphology and Mediterranean-type climate have largely shaped the state's freshwater lakes, streams, rivers, and wetlands. Now, however, freshwater ecosystems are stressed by water diversion, land use changes, non-native specie.....»»
Machine learning leads to first regional scale forest mapping using 1-meter measurements
An Arkansas researcher has developed the first high-resolution forest canopy cover dataset for an entire state, providing valuable insights for forest management and conservation to a major economic sector in Arkansas......»»
Tundra vegetation to grow taller, greener through 2100, study finds
Warming global climate is changing the vegetation structure of forests in the far north. It's a trend that will continue at least through the end of this century, according to NASA researchers. The change in forest structure could absorb more of the.....»»
