Experimental data validates new theory for molecular diffusion in polymer matrices
After several years of developing the theoretical ideas, University of Illinois Urbana-Champaign researchers have validated multiple novel predictions about the fundamental mechanism of transport of atoms and molecules (penetrants) in chemically complex molecular and polymer liquid matrices.
Geoscientists analyze fans' earthshaking reaction to win over Alabama
Fans inside and outside Tiger Stadium erupted with excitement as they watched their team beat Alabama in overtime. At the same time, a seismometer on LSU's campus captured the excitement, recording two distinctive seismic wave events. The first came at 10:03 p.m. after LSU football quarterback Jayden Daniels scored a touchdown from a 25-yard run. The second event came just minutes later at 10:06...
Iranian regime 'doubling down' on media manipulation in response to recent protests, analysis shows
The Iranian regime is "doubling down" on the manipulation of media in response to recent protests to create armed conflict between different ethnic groups, an expert has warned.
How squid and octopus get their big brains
Cephalopods—which include octopus, squid, and their cuttlefish cousins—are capable of some truly charismatic behaviors. They can quickly process information to transform shape, color, and even texture, blending in with their surroundings. They can also communicate, show signs of spatial learning, and use tools to solve problems. They're so smart, they can even get bored.
Study: Germans more satisfied with democracy as a form of government
Public satisfaction with democracy in Germany has risen over the past two years, while in some cases extreme right-wing attitudes have declined significantly. At the same time, hatred of migrants, women, Muslims and other groups in Germany has increased and become widespread. In addition, stronger desires for authority can be observed in the wake of the pandemic. These are key findings of the...
Expert Comment: Is the future of transport electric? We have to do everything, and fast
Focusing solely on electric vehicles and technology that is not proven at scale is actually slowing down the path to zero emissions—it diverts resources and political will away from other solutions. In reality, if we are to meet the decarbonization targets of the Paris Agreement by 2050, we also need to focus on the movement of people and goods—and look at introducing traffic reduction...
Nazi propaganda from 1927–1945 reveals the role of dehumanization of Jews in the Holocaust
A linguistic analysis of Nazi propaganda suggests that dehumanization of Jews shifted over time, with propaganda after the onset of the Holocaust portraying Jews as having a greater capacity for agency, relative to earlier propaganda focused on disengaging moral concern. Alexander Landry of the Stanford Graduate School of Business, California, and colleagues present these findings in the...
Ambition to succeed despite adversity motivates people from diverse backgrounds to pursue legal careers, study shows
A desire to succeed despite adversity motivates people to pursue a legal career, but barriers caused by finances and careers advice are obstacles, a new study suggests.
'Young, male and aimless': Why are men in India delaying marriage?
Marriage is highly revered in India, so it's notable that men are marrying later, said sociologist and demographer Alaka Malwade Basu, and not because they're choosing to live it up as bachelors before settling down.
Truly chiral phonons observed in three-dimensional materials for the first time
Chirality is the breaking of reflection and inversion symmetries. Simply put, it is when an object's mirror images cannot be superimposed over each other. A common example are your two hands—while mirror images of each other, they can never overlap. Chirality appears at all levels in nature and is ubiquitous.
US political partisanship affects first impressions of faces
In an experimental study, participants' first impressions of photos of strangers' faces were strongly influenced by disclosure of the stranger's political partisanship. Brittany Cassidy of the University of North Carolina at Greensboro, U.S., and colleagues present these findings in the open-access journal PLOS ONE on November 9, 2022.
Road collisions more likely for takeaway delivery riders working in the gig economy
Motorcyclists delivering hot food who pick up jobs through digital platforms are more likely to be in a collision where their bike is damaged or someone is injured than those directly employed by restaurants, finds research by UCL.
Scientists cite need for more research on leadership development in adolescence
Greta Thunberg, David Hogg and Malala Yousafzai, all teenagers when their activism caught the world's attention, are proof that leadership develops well before adulthood.
Electrons zip along quantum highways in new material
Researchers at the University of Chicago's Pritzker School of Molecular Engineering (PME) have discovered a new material, MnBi6Te10, which can be used to create quantum highways along which electrons can move. These electron thoroughfares are potentially useful in connecting the internal components of powerful, energy-efficient quantum computers.
New pterosaur species identified in sub-Saharan Africa
With wings spanning nearly 16 feet, a new species of pterosaurs has been identified from the Atlantic coast of Angola.
Genome sequencing supports Nile rat animal model for diabetes research
Model organisms are essential for biomedical research and have enabled many important scientific discoveries. The ability to sequence the genomes of these models is a powerful tool to study the genetic factors that impact human health.
Engineers ready innovative robotic servicing of geosynchronous satellites payload for launch
Engineers at the U.S. Naval Research Laboratory's (NRL) Naval Center for Space Technology (NCST) recently completed robotic payload component level testing for the Defense Advanced Research Projects Agency (DARPA) Robotic Servicing of Geosynchronous Satellites (RSGS) program.
Pacemaker channel discovery could lead to better heart drugs
The mechanism by which fat-related molecules called lipids regulate pacemaker ion channel proteins, which help control the heart rhythm, has been revealed in a study from researchers at Weill Cornell Medicine.
The evolution of tree roots may have driven mass extinctions
The evolution of tree roots may have triggered a series of mass extinctions that rocked the Earth's oceans during the Devonian Period over 300 million years ago, according to a study led by scientists at IUPUI, along with colleagues in the United Kingdom.
Oil and gas emissions up to three times what is reported: monitor
Planet-heating emissions from oil and gas production could be three times higher than reported, according to a satellite monitoring project launched Wednesday that the UN chief said made it harder to "cheat".
More than 130 seals found dead on Caspian beaches
More than 130 endangered seals have been found dead on Kazakh beaches of the Caspian Sea, officials said Wednesday.
Turtles in demand as pets, leading to a spike in poaching
Swimming in two plastic bins inside a brightly lit and sterile quarantine room at a Rhode Island zoo, 16 quarter-sized turtle hatchlings represent a growing worry for conservationist Lou Perrotti.
SARS-CoV-2 alters RNA in infected cells, study reveals
For the first time, scientists at the Federal University of São Paulo (UNIFESP) in Brazil have shown that infection by SARS-CoV-2, the virus that causes COVID-19, changes the functioning of host cell RNA. They arrived at this conclusion by analyzing 13 datasets obtained during four studies of viral, human and animal cell RNA.
