Large mammals shaped the evolution of humans in Africa, says ecologist
That humans originated in Africa is widely accepted. But it's not generally recognized how unique features of Africa's ecology were responsible for the crucial evolutionary transitions from forest-inhabiting fruit-eater to savanna-dwelling hunter. Th.....»»
Cosmic microwave background experiments could probe connection between cosmic inflation, particle physics
Various large-scale astrophysical research projects are set to take place over the next decade, several of which are so-called cosmic microwave background (CMB) experiments. These are large-scale scientific efforts aimed at detecting and studying CMB.....»»
How large turkey vultures remain aloft in thin air
Mountain hikes are invigorating. Crisp air and clear views can refresh the soul, but thin air presents an additional challenge for high-altitude birds. "All else being equal, bird wings produce less lift in low density air," says Jonathan Rader from.....»»
When it comes to DNA replication, humans and baker"s yeast are more alike than different, scientists discover
Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies published in the journals Science and Proceedings of the National Academy of Scienc.....»»
Study shows link between asymmetric polar ice sheet evolution and global climate
Joint research led by Professor An Zhisheng from the Institute of Earth Environment of the Chinese Academy of Sciences has revealed the pivotal role of the growth of the Antarctic ice sheet and associated Southern Hemisphere sea ice expansion in trig.....»»
New insights into one of Europe"s oldest dinosaurs
A comprehensive new description of Plateosaurus trossingensis provides valuable information on the evolution, lifestyle and family tree of early dinosaurs. During this analysis, bone injuries were discovered, which paleontologists investigated in mor.....»»
Sea level changes shaped early life on Earth, fossils show
A newly developed timeline of early animal fossils reveals a link between sea levels, changes in marine oxygen, and the appearance of the earliest ancestors of present-day animals......»»
Climate change may lead to shifts in vital Pacific Arctic fisheries
Marine fisheries are an essential source of protein for a large part of the world's population, as well as supporting around 390 million livelihoods and an industry worth approximately US$ 141 billion, according to the UN FAO. Yet, climate change pre.....»»
Does AI in the classroom facilitate deep learning in students?
Multitasking robots collaborate with humans in large warehouses, and chatbots respond to queries on banking websites. Artificial intelligence assistants even sort documents for law firms. William & Mary Assistant Professor of Computer Science Janice.....»»
Penguin wing fossil shows importance of Zealandia in penguin evolution
Three small fossil penguin bones, collected in South Canterbury in 1987, are now shedding new light on how penguin wings have evolved. A new study, published in the Journal of the Royal Society of New Zealand, describes a new species of penguin that.....»»
Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers
Much of the water in the U.S. West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions asso.....»»
Practical strategies to mitigate risk and secure SAP environments
Large companies use ERP applications to manage business processes, including payroll and financial planning. This is precisely why bad actors are taking a renewed interest in these legacy systems – and succeeding. In this Help Net Security vide.....»»
Mass extinction 66 million years ago triggered rapid evolution of bird genomes, study finds
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began......»»
S.Africa to trial vaccination of seals after first rabies outbreak
Cape fur seals with rabies have infected at least seven people in South Africa and vaccinations will be trialed to try to contain what is the first documented outbreak of the disease in a marine mammal population, a coastal management official said W.....»»

The sun"s corona is weirdly hot, and Parker Solar Probe rules out one explanation
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures, according to University of Michigan research published in The Astrophysical Journal L.....»»
Researchers discover high levels of non-coding RNAs in testes, suggesting new roles in sperm function and evolution
Researchers at the University of Toronto have mapped the spatial distribution of around 700 long non-coding RNAs, otherwise known as lncRNAs, in the testes. The team discovered much higher levels of lncRNAs in the testes than had been previously esti.....»»
I studied ShotSpotter in Chicago and Kansas City—here"s what people using this technology should know
Like many large cities in the U.S., Detroit's gun violence rate has fluctuated since the COVID-19 pandemic and the unrest after the murder of George Floyd in 2020. The city's murder rate increased nearly 20% that year, meaning the city had the second.....»»
Agricultural soils are efficient ice nucleating particles in the southern great plains
INPs are a rare subset of atmospheric aerosol that can initiate ice formation in clouds. There is a significant gap between scientists' ability to measure INPs and to predict their concentrations and variability in large-scale weather and climate mod.....»»
