People, not the climate, found to have caused the decline of the giant mammals
For years, scientists have debated whether humans or the climate have caused the population of large mammals to decline dramatically over the past several thousand years. A new study from Aarhus University confirms that climate cannot be the explanat.....»»
Cats playing fetch: Research investigates how the game unfolds
Cats tend to dictate games of fetch with their owners and most cats who play fetch learned to do so without explicit training, according to a survey of 924 cat owners published in Scientific Reports. The findings also highlight the variety of objects.....»»
Cockroaches can transmit antimicrobial resistance genes between groups
A new paper describes a study of antimicrobial resistance (AMR) transmission among cockroaches, with implications for AMR transmission in humans. The study was published in mSystems......»»
AI provides more accurate analysis of prehistoric and modern animals
A new Rice University study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert......»»
Researchers review miniaturized electrochemical sensor technologies for rapid heavy metal detection
Heavy metals (HMs) are metals with high densities and atomic weights. Originating from geological processes or human activities, including mining, industrial production, and petrochemical plants, they are toxic to humans and animals and considered as.....»»
Parrots and songbirds have evolved distinct brain mechanisms, study shows
When humans learn to speak a language, we learn to produce new vocalizations and use them flexibly for communication, but how the brain is able to achieve this is an important but largely unanswered question, according to Zhilei Zhao, Klarman Fellow.....»»
Climate tipping points are nearer than you think. Our new report warns of catastrophic risk
It's now almost inevitable that 2023 will be the warmest year ever recorded by humans, probably the warmest for at least 125,000 years......»»
Social robots leave students wanting, education researchers find
Social robots, artificial intelligence (AI) systems designed to interact with humans, are marketed as capable of fulfilling certain human roles. Elementary and middle school students who interacted with one of these robots in the classroom for 10 wee.....»»
Grunt or whistle: Successful honey-hunters know how to communicate with wild honey-seeking birds
In many parts of Africa, humans cooperate with a species of wax-eating bird called the greater honeyguide, Indicator indicator, which leads them to wild bees' nests with a chattering call. By using specialized sounds to communicate with each other, b.....»»
Novel viral treatment found to be effective against devastating bone cancer in dogs
Researchers from the University of Minnesota partnered with Mayo Clinic to conduct a groundbreaking study that could offer hope for dogs, and potentially humans, diagnosed with osteosarcoma— a devastating bone cancer predominantly affecting childre.....»»
If humans disappeared, what would happen to our dogs?
For many of us, dogs are our best friends. But have you wondered what would happen to your dog if we suddenly disappeared? Can domestic dogs make do without people?.....»»
Fruit fly study finds blue light exposure may affect processes related to aging
In a study on fruit flies, daily low-intensity blue light exposure (BLE), similar to that experienced daily by billions of humans in the form of LED lighting and device screens, changed flies at the sub-cellular level, affecting processes related to.....»»
Environmental monitoring of bacteria can strengthen community preparedness against diseases
A variety of potentially disease-causing bacteria exist in the Baltic Sea and in Swedish lakes. Karolina Eriksson, a doctoral student at the Industrial Doctoral School at Umeå University, reveals future health risks for humans in the light of climat.....»»
Study reveals genes that set humans apart from other primates in cognitive ability
An international team led by researchers at the University of Toronto has uncovered over 100 genes that are common to primate brains but have undergone evolutionary divergence only in humans—and which could be a source of our unique cognitive abili.....»»
Bird feeding may give humans something to chirp about
Associate professor in the Department of Fish and Wildlife Conservation at Virginia Tech, Ashley Dayer is the lead author of an article published in People and Nature that argues not only for the acknowledgment of the activity's benefit to humans, bu.....»»
Don’t count on NASA to return humans to the Moon in 2025 or 2026, GAO says
No surprise: SpaceX's lunar lander and Axiom's spacesuits pace the Artemis III schedule. Enlarge / A crescent Earth rises over the horizon of the Moon in this view from NASA's Orion spacecraft on the unpiloted Artemis I test flig.....»»
Researchers crack the cellular code on protein folding, offering hope for many new therapeutic avenues
While we often think of diseases as caused by foreign bodies—bacteria or viruses—there are hundreds of diseases affecting humans that result from errors in cellular production of proteins......»»
MicroRNA holds clues to why some mammals are cancer-prone
Researchers at the College of Veterinary Medicine (CVM) have identified an important pathway that reveals why some mammals, like humans, dogs, and cats, regularly develop mammary cancer while others, such as horses, pigs, and cows, rarely do......»»
Aging societies more vulnerable to collapse, suggests analysis
Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies. A new study, which holds implications for the modern world, provides the first qu.....»»
Researchers suggest use of natural fermentation may have led to early human brain size increase
A trio of researchers with varied backgrounds is suggesting in an article published in the journal Communications Biology that eating naturally fermented foods may have led to an increase in brain size for early humans. In their paper, Katherine Brya.....»»
