In a series of tea party-like experiments, Johns Hopkins University researchers demonstrate for the first time that apes can use their imagination and play pretend, an ability thought to be uniquely human.
Phys.org / Increasing pesticide toxicity threatens global biodiversity protection goal: Only one country is currently on target
At the 15th UN Biodiversity Conference (COP15) in Montreal, Canada, in 2022, nations committed to reducing the risks associated with pesticide use in agriculture by 50% by 2030. A new study by a research team from RPTUKaiserslautern-Landau, ...
Tech Xplore / AI agents debate more effectively when given personalities and the ability to interrupt
In a typical online meeting, humans don't always wait politely for their turn to speak. They interrupt to express strong agreement, stay silent when they are unsure, and let their personalities shape the flow of the discussion. ...
Medical Xpress / How 'invisible' vaccine scaffolding boosts HIV immune response
One of the biggest hurdles in developing an HIV vaccine is coaxing the body to produce the right kind of immune cells and antibodies. In most vaccines, HIV proteins are attached to a larger protein scaffolding that mimics ...
Phys.org / Teaching machines to design molecular switches
In biology, many RNA molecules act as sophisticated microscopic machines. Among them, riboswitches function as tiny biological sensors, changing their 3D shape upon binding to a specific metabolite. This shape-change acts ...
Phys.org / Scientists explain why methane spiked in the early 2020s
A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land increased atmospheric methane at an unprecedented rate in the early 2020s, an international ...
Phys.org / Philadelphia communities help AI machine learning get better at spotting gentrification
Over the last several decades, urban planners and municipalities have sought to identify and better manage the socioeconomic dynamics associated with rapid development in established neighborhoods. The term "gentrification" ...
Phys.org / Study finds numbing the mouth may speed up silent reading
Parents often tell their children to sound out the words as they are learning to read. It makes sense: Since they already know how to speak, the sound of a word might serve as a clue to its meaning.
Phys.org / Two-day-old babies show brain signs of rhythm prediction, study finds
Babies are born with the ability to predict rhythm, according to a study published February 5 in the open-access journal PLOS Biology by Roberta Bianco from the Italian Institute of Technology, and colleagues.
Phys.org / Global map catalogs 459 rare continental mantle earthquakes since 1990
Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in our planet's mantle, the layer sandwiched between the thin crust and Earth's molten core. The new ...
Medical Xpress / Extreme temperature changes increase number of out-of-hospital cardiac arrests, model finds
Out-of-hospital cardiac arrest, or OHCA, is a leading cause of mortality worldwide and 90% of cases are fatal. Patients lose cardiac function and circulation, and every minute they remain untreated decreases the likelihood ...
