Anisotropic zoning in the upper crust of the Tianshan Tectonic Belt
The collision between the Indian and Eurasian plates resulted in the formation of the Tianshan Tectonic Belt; however, the formation mechanism of Tianshan and the construction of a dynamic model explaining it remain to be realized and an integrated u.....»»
A price on their heads? Implications of international trade for African hornbills in Cameroon
Tropical birds known for their massive bills, hornbills include 32 Asian and 27 African species in the avian family Bucerotidae. Many hornbills have a casque on their upper mandible, which in some species is spectacularly colorful. Many species also.....»»
Researchers study carbon capture in Upper Newport Bay salt marshes
Despite covering just 2% of the ocean, coastal wetlands—such as tidal salt marshes, mangrove forests and seagrass beds—are responsible for storing nearly half of all carbon found in ocean sediment. These "blue carbon" ecosystems naturally absorb.....»»
Research team designs AI approach to drought zoning in Canada
A recent study by the University of Ottawa and Laval University shows that climate change may cause many areas in Canada to experience significant droughts by the end of the century. In response, the researchers have introduced an advanced AI-based m.....»»
Study tracks decades of extreme heat, cold in Upper Midwest
Researchers analyzed meteorological data from nine Upper Midwest states from 1979–2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts o.....»»
Lithospheric oddities may be sculpting continental interiors
Interactions between neighboring tectonic plates can push parts of Earth's surface up or down to form notable features, such as the Andes and the Himalayas. The forces that sculpt the Earth's surface far from plate edges are less well understood. For.....»»
Monarch butterfly numbers have dropped this summer in Illinois, Upper Midwest, experts say
An expert has confirmed what backyard gardeners and amateur naturalists have been saying for weeks: There are fewer monarch butterflies in Illinois this summer......»»
Mercedes S-Class production reduced to one shift on slow demand
Sales of the upper-premium sedan have plunged in China, the U.S. and Europe as demand for high-end cars stalls......»»
Facing “financial crisis,” Russia on pace for lowest launch total in 6 decades
"This forces us to build a new economy in severe conditions." Enlarge / A Soyuz 2.1b rocket booster with a Frigate upper stage block, the Meteor-M 2-1 meteorological satellite, and 18 small satellites launched from the Vostochny.....»»
The biggest-ever sample of core material from Earth"s mantle could have valuable clues into the origins of life
If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic c.....»»
China’s Long March 6A rocket is making a mess in low-Earth orbit
After nearly every flight, the upper stage of this rocket breaks apart in orbit. Enlarge / Debris from the upper stage of China's Long March 6A rocket captured from the ground by Slingshot Aerospace. (credit: Slingshot Aerospace.....»»
A new report finds Boeing’s rockets are built with an unqualified work force

Recovery of rocks that originated in Earth"s mantle could reveal secrets of planet"s history
Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component......»»

Erosion, tectonic uplift, and a human-built dam have all helped shape the Upper Lake Powell area in Utah......»»
Green belts need modernizing—a more "multifunctional" approach can benefit people and planet
Green belts are more than just spaces; for many people, they're places providing a brief escape from the city. Land designated as green belt—and protected from building—can also store carbon and hold water at times of flooding and drought......»»
Indonesia’s tiny hobbits descended from even smaller ancestors

First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Scientists find a human "fingerprint" in the upper troposphere"s increasing ozone
Ozone can be an agent of good or harm, depending on where you find it in the atmosphere. Way up in the stratosphere, the colorless gas shields the Earth from the sun's harsh ultraviolet rays. But closer to the ground, ozone is a harmful air pollutant.....»»
There are 2,000-plus dead rockets in orbit—here’s a rare view of one

Study reveals the Southwest Tianshan Mountains contribute the majority of the Kyzylkum desert sand and river system
Arid Central Asia is an important dust source in the northern hemisphere, which has a significant impact on the ecological environment of Central Asia, Northwest China and even the East Asian monsoon region. The Kyzylkum Desert is one of the biggest.....»»
New study supports stable mantle chemistry dating back to Earth"s early geologic history
A new analysis of rocks thought to be at least 2.5 billion years old by researchers at the Smithsonian's National Museum of Natural History helps clarify the chemical history of Earth's mantle—the geologic layer beneath the planet's crust......»»
