Medical Xpress / People's facial mimicry predicts their choices, study finds
In social situations, humans often copy the facial expressions of others who they are interacting with. This phenomenon, known as facial mimicry, is widely reported and has been linked to social connection and an empathic ...
Medical Xpress / Scientists grow mini brains to uncover cells behind autism-related brain overgrowth
A new study in the lab of Jason Stein, Ph.D., modeled brain development in a dish to identify cells and genes that influence infant brain growth, a trait associated with autism.
Phys.org / More than 16,000 dinosaur tracks discovered at a site in Bolivia
Scientists have discovered the single largest dinosaur track site in the world in Carreras Pampa, Torotoro National Park, Bolivia. The tracks were made about 70 million years ago, in the late Cretaceous Period, by theropods—bipedal ...
Phys.org / Vast freshwater reserves found beneath salinity-stressed coastal Bangladesh
Despite its tropical climate and floodplain location, Bangladesh—one of the world's most densely populated nations—seasonally does not have enough freshwater, especially in coastal areas. Shallow groundwater is often ...
Phys.org / Pahon Cave provides a look into 5,000 years of surprisingly stable Stone Age tool use
The Pahon Cave in Gabon offers archaeologists a well-preserved look into the Late Stone Age time period in central Africa, thanks to the stratified layers of guano-based sediment. This is in contrast with much of the surrounding ...
Phys.org / New 'cloaking device' concept shields electronics from disruptive magnetic fields
University of Leicester engineers have unveiled a concept for a device designed to magnetically "cloak" sensitive components, making them invisible to detection.
Phys.org / A universal law could explain how large trades change stock prices
Financial markets are often seen as chaotic and unpredictable. Every day, traders around the world buy shares and sell assets in a whirlwind of activity. It looks like a system of total randomness—but is it really?
Phys.org / Physicists experimentally realize a quantum Hilbert hotel
(Phys.org)—In 1924, the mathematician David Hilbert described a hotel with an infinite number of rooms that are all occupied. Demonstrating the counterintuitive nature of infinity, he showed that the hotel could still accommodate ...
Phys.org / New law implies thermodynamic time runs backwards inside black holes
(Phys.org)—Black holes are known to have many strange properties, such as that they allow nothing—not even light—to escape after falling in. A lesser known but equally bizarre property is that black holes appear to ...
Phys.org / 8.2 ka event triggered social transformation, not destruction, at China's Jiahu site
In a recent study, Dr. Yunchen Tan and colleagues examined the response of the North China Plain settlement of Jiahu to the abrupt climatic 8.2 ka event. They found that Jiahu not only survived but also demonstrated remarkable ...
Phys.org / Quantum entanglement could connect drones for disaster relief, bypassing traditional networks
Any time you use a device to communicate information—an email, a text message, any data transfer—the information in that transmission crosses the open internet, where it could be intercepted. Such communications are also ...
Phys.org / Nanoplastics have diet-dependent impacts on digestive system health, study finds
Plastics are not inert: they gradually break into fragments over time, forming micro- and then nanoplastics (i.e., particles
