Ancient DNA study reveals population history of Western Tibetan Plateau
According to a study published in Current Biology on May 22, the genetic components of the ancient populations in the western Tibetan Plateau are closest to ancient populations in the southern Tibetan Plateau, and their major genetic components have.....»»
Last surviving woolly mammoths were inbred but not doomed to extinction, genomic analysis suggests
The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland......»»
Image: Proba-2"s glimpse of home

Three new extinct walnut species discovered in high Arctic mummified forest
In a new study, scientists describe three new, but long-extinct, walnut species on an island above the Arctic Circle. The fossils were discovered further north than any known walnut species, living or extinct, and represent some of the oldest-known r.....»»
New study investigates the reconstruction of the intertropical convergence zone
The study focuses on the so-called Intertropical Convergence Zone (ITCZ), a low-pressure trough near the equator whose position and intensity changes seasonally with the position of the sun. Trade winds from the northern and southern hemispheres meet.....»»
Teaching biology—no more stressing out over structural formulas
Structural formulas are a source of dread for many students, but they're an essential tool in biology lessons. A joint study has shown that the stress levels of students working with chemical formulas are significantly reduced if they are given simpl.....»»
Study projects loss of brown macroalgae and seagrasses with global environmental change
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and.....»»
What can social media tell us about public views on climate change?
IIASA researchers contributed to a new study, analyzing the main narratives in public discussions of climate change on social media. The research is published in the journal Current Research in Environmental Sustainability......»»
Pacific cod can"t rely on coastal safe havens for protection during marine heat waves, study finds
During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new Oregon State.....»»

Only 4% of teen football academy prospects make top tier, study finds
Just 4% of talented teen academy prospects make it to the top tier of professional football, a new study has shown. A sample of nearly 200 players, aged between 13–18, also revealed only 6% of the budding ballers even go on to play in lower leagues.....»»
Study determines stellar mass and origin of a protostellar system
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have conducted molecular line observations of a protostellar system known as VLA 1623. Results of the observational campaign, published June 18 on the pre-print server arXiv,.....»»
Ecologists reconstruct history of biodiversity in Indo-Australian archipelago and its rise as a hotspot
The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a my.....»»
New strategy to obtain carbon nanotube fibers with higher dynamic strength
In a study published in Science on June 21, Prof. Jian Muqiang from Peking University and the Beijing Graphene Institute and others developed a strategy to fabricate carbon nanotube fibers with the dynamic strength up to 14 GPa......»»
Changing water conservation attitudes positively impacts water availability, study finds
The increased demand for clean water and its limited supply has made water management one of the most pressing challenges facing society today. Changing attitudes about water conservation could significantly impact water consumption and help address.....»»
Wind tunnel study shows hypersonic jet engine flow can be controlled optically
What if the future of space travel were to look less like Space-X's rocket-based Starship and more like NASA's "Hyper-X," the hypersonic jet plane that, 20 years ago this year, flew faster than any other aircraft before or since?.....»»
Do vertebrate populations really decline so much? Calculations indicating severe declines might be wrong, says study
A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet......»»
Phytochemical diversity and herbivory are higher in tropical forests, says study
It is widely accepted that biological interactions are stronger or more important in generating and maintaining biodiversity in the tropics than in temperate regions. However, this hypothesis has not been fully tested in ecology and evolutionary biol.....»»
Early childhood problems linked to persistent school absenteeism
Children who are not considered "school-ready" by their teachers are more than twice as likely to become persistently absent at some point in their education, according to a new study led by the University of Leeds......»»
Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba has used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his.....»»
