Ancient genes pinpoint when humans and Neanderthals mixed and mingled
Neanderthals and humans likely mixed and mingled during a narrow time frame 45,000 years ago, scientists reported Thursday......»»
Biodegradable microplastics study helps quantify their climate change and ecotoxicity impacts
Over 20 million tons of plastic are estimated to end up in the environment every year, with much of it breaking down into microplastics that are harmful to the health of humans and wildlife. Biodegradable and bio-based plastics made from organic mate.....»»
AI, as it stands today, is a valuable tool for the auto industry but a poor substitute for humans
As the industry experiments with artificial intelligence, business owners need to be aware of the technology's promise and its limitations......»»
Was organized society an agitating or pacifying force in ancient Andes populations?
The extent to which "civilization" heightens or lessens the likelihood of violent conflict throughout human history has remained one of the most enduring questions among anthropologists. But a new collaborative study of archaeological groups from the.....»»
Rare fossils of extinct elephant document the earliest known instance of butchery in India
During the late middle Pleistocene, between 300 and 400 thousand years ago, at least three ancient elephant relatives died near a river in the Kashmir Valley of South Asia. Not long after, they were covered in sediment and preserved along with 87 sto.....»»
Island arcs study reveals ancient connections between ocean chemistry and volcanic rocks
Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left an imprint on volcanic rocks formed in island arcs. Island arcs, which arise from volcanic activity along.....»»
Archaeologist reveals factors affecting ocher application in ancient burials at Khok Phanom Di
A study by Dr. Sarah Elizabeth Paris published in the International Journal of Osteoarcheology has investigated the link between ocher burials and chronology, age, sex mobility and funerary tradition at the site of Khok Phanom Di (~4000–3500BP), Th.....»»
Integrated space-ground technologies empower archaeological research into ancient tombs
A team of international researchers has employed an integrated approach to uncover the mysteries of the Eastern Mausoleum of Qin State, an ancient royal burial site from China's Warring States period......»»

Saturday Citations: Brown dwarf actually brown dwarfs; the adaptability of ice-age humans; archaeologists excited
This week, researchers discovered a near-Earth microquasar that sheds new light on sources of relativistic outflows. Doctors reported finding a triphallic gentleman. And neuroscientists reported on modest cognitive boosts from short (or "acute," in c.....»»
Controlling sound waves with Klein tunneling improves acoustic signal filtration
In the context of sensory modalities, eyes work like tiny antennae, picking up light, electromagnetic waves traveling at blistering speeds. When humans look at the world, their eyes catch these waves and convert them into signals the brain reads as c.....»»
Study of wild type mosquitoes in Burkina Faso discovers new signs of insecticide resistance
One of the main discoveries of a new study is the identification of new variants in genes associated with insecticide resistance in Anopheles mosquitoes, the primary vectors of malaria in West Africa, and potential novel resistance mechanisms, emphas.....»»
It’s increasingly unlikely that humans will fly around the Moon next year
It's not just Orion's heat shield; the mission's ground systems are running out of time. Don't book your tickets for the launch of NASA's Artemis II mission next year just yet. W.....»»
In search of evidence of ancient human existence, researchers traverse the inhospitable Namib desert
Strewn across the Namib desert is a treasure trove of stone tools of which little is known because getting to them is so difficult. There are few roads and vehicles have limited access in this protected area that lies in the desert of western Namibia.....»»
Microbiome studies in humans and zoo animals pave the way for new drug development
Microorganisms do not just colonize the body of mammals during infections. Billions of microbes can be found on and in healthy humans and animals at any given time, communicating with each other via chemical signals and thus influencing their health......»»
Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»
Identifying the genes that viruses "steal" from ocean microbes
The microbes that cycle nutrients in the ocean don't do the work on their own—the viruses that infect them also influence the process. It's a vital job for the rest of the planet, enabling oceans to absorb half of the human-generated carbon in the.....»»
Ancient ‘Age of Dinosaurs’ Seafloor Found beneath Pacific Ocean
A vast, ancient slab of seafloor plunged beneath the Pacific Ocean and has hovered in Earth’s mantle for more than 120 million years, a new study suggests.....»»
DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»
Humans have near-equal numbers of male and female babies, unlike many other animals—a new genetic study looks for clues
We know that boys and girls are produced in much the same frequency. But how—and why—is this 1:1 ratio achieved?.....»»
