NASA administrator says China is failing to meet 'responsible standards' for space debris, after parts of an uncontrolled rocket landed in the Indian Ocean

Former Senator Bill Nelson. NASA/Bill Ingalls NASA's Bill Nelson on Sunday said China hadn't met "responsible standards" for uncontrolled debris. Debris from a Chinese rocket landed in the Indian Ocean on Sunday. Space agencies and private companies need to "act responsibly and transparently," he said.

The ants, bees and wasps of Canada, Alaska and Greenland - a checklist of 9250 species

A series of distributional lists is being published for a group of organisms that, despite its size and diversity, is still poorly known: the insect order Hymenoptera, which includes ants, bees and wasps. The surveyed area spreads across Canada, Alaska and Greenland. When complete, this will be the largest species checklist for northern North America. The checklists are being published as a topical collection of eleven papers in the open-access, peer-reviewed Journal of Hymenoptera Research.

Bees thrive where it's hot and dry: A unique biodiversity hotspot located in North America

Rarely has the United States-Mexico border become the source of positive news of lately. However, a new study, published in the Journal of Hymenoptera Research, demonstrates it's in fact one of the world's top biodiversity hotspots for bees. A multi-year survey led by Robert Minckley of the University of Rochester found more than 470 bee species in 16km2 of Chihuahuan Desert, equivalent to 14% of all known bee species from the United States.

New GSA Bulletin articles published ahead of print in April

The Geological Society of America regularly publishes articles online ahead of print. For April, GSA Bulletin topics include multiple articles about the dynamics of China and Tibet; the Bell River hypothesis that proposes that an ancestral, transcontinental river occupied much of northern North America during the Cenozoic Era; new findings in the climatic history during one of Earth's coldest periods: The Late Paleozoic Ice Age; and the age an nature of the Chicxulub impact crater.

200-year old poop shows rural elites in New England had parasitic infections

In the early 19th century in North America, parasitic infections were quite common in urban areas due in part to population growth and urbanization. Prior research has found that poor sanitation, unsanitary privy (outhouse) conditions, and increased contact with domestic animals, contributed to the prevalence of parasitic disease in urban areas. A new study examining fecal samples from a privy on Dartmouth's campus illustrates how rural wealthy elites in New England also had intestinal parasitic...

Newly identified saber-toothed cat is one of largest in history

A giant saber-toothed cat lived in North America between 5 million and 9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported today in a new study.

Was North America populated by 'stepping stone' migration across Bering Sea?

A new study from the University of Kansas just published in the open-access journal Comptes Rendus Geoscience, may answer "one of the greatest mysteries of our time . . . when humans made the first bold journey to the Americas."

Cave deposits reveal Pleistocene permafrost thaw, absent predicted levels of CO2 release

Expanding the study of prehistoric permafrost thawing to North America, researchers found evidence in mineral deposits from caves in Canada that permafrost thawing took place as recently as 400,000 years ago, in temperatures not much warmer than today. But they did not find evidence the thawing caused the release of predicted levels of carbon dioxide stored in the frozen terrain.

Spring forest flowers likely key to bumble bee survival, Illinois study finds

For more than a decade, ecologists have been warning of a downward trend in bumble bee populations across North America, with habitat destruction a primary culprit in those losses. While efforts to preserve wild bees in the Midwest often focus on restoring native flowers to prairies, a new Illinois-based study finds evidence of a steady decline in the availability of springtime flowers in wooded landscapes.

New duckbilled dinosaur discovered in Japan

An international team of paleontologists has identified a new genus and species of hadrosaur or duck-billed dinosaur, Yamatosaurus izanagii, on one of Japan's southern islands.The fossilized discovery yields new information about hadrosaur migration, suggesting that the herbivors migrated from Asia to North America instead of vice versa. The discovery also illustrates an evolutionary step as the giant creatures evolved from walking upright to walking on all fours.

A tiny, invasive bug and the climate crisis are changing how guitars are made, and shifting the course of music history

Fender; Marianne Ayala/Insider Swamp ash is a wood prized by guitar makers and musicians for its light weight and resonant sound. But flooding, and a tiny bug, threaten the wood and the sound that is synonymous with rock music. Fender is phasing out ash after 70 years of use, and ash trees could soon disappear altogether.

Was Cascadia's 1700 earthquake part of a sequence of earthquakes?

The famous 1700 Cascadia earthquake that altered the coastline of western North America and sent a tsunami across the Pacific Ocean to Japan may have been one of a sequence of earthquakes, according to new research presented at the Seismological Society of America (SSA)'s 2021 Annual Meeting.

A whopping 2.5 billion fully grown T. rexes walked the Earth in the course of the species' existence, paleontologists found

A T. rex depicted in the 1993 film "Jurassic Park." Universal Pictures The Tyrannosaurus rex was around for 2.5 million years before the dinosaurs went extinct. A new study suggests that a total of 2.5 billion adult T. rexes lived and died during that period. Paleontologists arrived at the figure by calculating the T. rex life span and population density. See more stories on Insider's business page. An adult Tyrannosaurus rex required a lot of space - and the prey therein - to survive....

North American deserts are a biodiversity hotspot for butterflies

By comparing the genetic diversity of butterflies in North America, researchers reporting in the journal iScience on March 23 found that the array of different evolutionary distinct groups of butterflies is particularly high in the deserts of Mexico and the southwestern United States. This may be an outcome of actively changing conditions in the Desert Southwest and more generally in the western portion of the continent.

Climate impacts drive east-west divide in forest seed production

Younger, smaller trees that comprise much of North America's eastern forests have increased their seed production under climate change. But older, larger trees that dominate western forests have been less responsive, a Duke-led study warns. This continental divide could limit western forests' ability to regenerate following large-scale diebacks linked to rising temperatures and intensifying droughts. Over time this might dramatically alter the composition and structure of 21st century North Amer...

Neanderthals died out after Earth's magnetic poles flipped, causing a climate crisis 42,000 years ago, a study says

An exhibit shows a Neanderthal family at the Neanderthal Museum in Krapina, Croatia, in February 2010. Reuters/Nikola Solic Earth's magnetic poles flipped 42,000 years ago, which may have triggered a global climate crisis, a new study found. The resulting changes in temperatures and radiation levels may have killed off many large mammals. The event may have ultimately contributed to the extinction of Neanderthals.

From mammoth teeth, scientists just pulled DNA that's more than 1 million years old - the oldest DNA ever found

An illustration of steppe mammoths, ancestors of woolly mammoths, based on newly sequenced DNA from teeth found in Siberia. Beth Zaiken/Centre for Palaeogenetics Scientists sequenced DNA from three ancient mammoth teeth found in Siberia. Some of the DNA was more than 1 million years old, making it the oldest DNA ever recovered. Genetics reveal these mammoths to be ancestors of both woolly mammoths and the mammoths that later occupied North America. Visit the Business section of Insider for...
