The emergence and perils of polarization
We can't understand polarization unless we analyze it as a complex system, argue SFI External Professor Scott Page (University of Michigan) and co-author Delia Baldassarri in a commentary for a special feature on the dynamics of political polarizatio.....»»
Two-dimensional bipolar magnetic semiconductors with electrically controllable spin polarization realized
Two dimensional (2D) magnetic semiconductors, integrating semiconductivity, ferromagnetism and low dimensionality, serve as the cornerstone for high-speed nanospintronic devices. However, the practical applications of nowadays 2D magnetic semiconduct.....»»
On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks
The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of phot.....»»
Preserved baby Neanderthal milk tooth shows earlier emergence than in humans
An international team of researchers studying a recovered Neanderthal milk tooth has found evidence of baby teeth growing faster and emerging earlier in the extinct human species than in modern humans. In their paper published in Proceedings of the R.....»»
Researchers find fake news about controversial topics contributes to political polarization
It's been a year since America experienced one of its most divisive elections in decades. Although President Joe Biden has called for unity, recent data from a new measurement, the USC Polarization Index, has shown political polarization remains as b.....»»
Lost Women of Science, Episode 3: The Case of the Missing Portrait
A missing portrait of physician and pathologist Dorothy Andersen takes us on a journey into the perils of memorialization—and who gets to be remembered. Pediatric intensivist Scott Baird hunts... -- Read more on ScientificAmerican.com.....»»
Ultra-large single-crystal WS2 monolayer
As silicon based semiconducting technology is approaching the limit of its performance, new materials that may replace or partially replace silicon in technology is highly desired. Recently, the emergence of graphene and other two-dimensional (2D) ma.....»»
A strategy to control the spin polarization of electrons using helium
Spintronics, also known as spin electronics, is a research field that explores how the intrinsic spin of electrons and its magnetic moment can be exploited by devices. Spintronic devices are promising for a wide range of applications, particularly fo.....»»
"Affective polarization" increasingly leaks into social situations, says new study
Partisanship is a particularly potent source of group identity in contemporary American politics, and a new paper co-written by a University of Illinois Urbana-Champaign expert in political psychology says the growing chasm between opposing groups is.....»»
Njordarchaeota, a new candidate for a sister group to eukaryotes
The emergence of eukaryotic cells is considered as a critical biological evolutionary event on Earth. The origin of eukaryotes and eukaryosis are frontier issues in both life and Earth sciences. Currently, it is widely accepted that the origin of euk.....»»
New game can help users identify, avoid online echo chambers
Every day, social media users are exposed to fake news and political polarization on social networks. What makes people vulnerable to believing false information they find online?.....»»
Controlling electrons and vibrations in a crystal with polarized light
The quantum behavior of atomic vibrations excited in a crystal using light pulses has much to do with the polarization of the pulses, say materials scientists from Tokyo Tech. The findings from their latest study offer a new control parameter for the.....»»
Climate change adaptation requires Indigenous knowledge
In rural and Indigenous communities with limited access to weather data, generations of farmers, fishers, herders, hunters and orchardists have relied on indicators such as the first snowfall, emergence of a certain plant or arrival of a bird species.....»»
A study of skull growth and tooth emergence reveals that timing is everything
Six, 12, and 18. These are the ages that most people get their three adult molars or large chewing teeth towards the back of the mouth. These teeth come in at a much later age than they do in our closest living relative, the chimpanzee, who get those.....»»
Political bias on social media emerges from users, not platform
In this era of political polarization, many accuse online social media platforms such as Twitter of liberal bias, intentionally favoring and amplifying liberal content and users while suppressing other political content......»»
Check out the amazing speakers joining us on Extra Cru… ahem, TechCrunch Live
It’s been an Extra Crunch summer. We’ve heard how to craft your pitch deck around the one thing that really hooks an investor, and how the industry experience of Retail Zipline’s Melissa Wong ticked every box for Emergence when rais.....»»
Researchers solve 20-year-old paradox in solar physics
In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been discovered while analyzing the polarization of sunlight, implies that the solar chromosphere (an important layer of the solar atmosphere) is pr.....»»
Metasurfaces control polarized light at will
For years, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have engineered metasurfaces to manipulate light based on its polarization state. That research has contributed to advances in polarization techno.....»»
Omnibiz gets $3M to digitize Nigeria’s informal B2B supply chain
Despite the prevalence of shopping malls and the emergence of VC-backed e-commerce companies like Jumia, informal retail in Africa is still king. A 2016 study by PwC states that 90% of sales in Africa’s major economies come through informal cha.....»»
Dubai-based buy now, pay later platform tabby raises $50M at $300M valuation
These past few years have seen the emergence of buy now, pay later services worldwide, with leading players raising buttloads of cash to serve an insatiable young adult population who don’t fancy credit cards or paying interest. In what seems t.....»»
