UTA regional assessment shows segregation, challenges

Social Sciences News - Tue, 07/17/2018 - 14:36
After extensively analyzing fair housing in North Texas, UTA researchers have discovered that in many cases, segregation and associated problems are becoming more pronounced.

Black children subjected to higher discipline rates than peers

Social Sciences News - Tue, 07/17/2018 - 12:29
Elementary school discipline policies that rely on expulsions or suspensions as punishment may be fostering childhood inequality, a new study shows.

New cost-effective instrument measures molecular dynamics on a picosecond timescale

General Physics - Tue, 07/17/2018 - 11:00
Studying the photochemistry, or chemical results of light, has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide "photo-protection" by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale.

Immigrants and their children are more likely to be profiled for citizenship

Social Sciences News - Tue, 07/17/2018 - 10:13
Law enforcement official are most likely to ask first- or second-generation Latinos for papers proving their right to be in the US. This is according to a study published in Springer's journal Race and Social Problems. Lead author, Maria Cristina Morales of the University of Texas at El Paso in the US, says the findings are important given that US law enforcement officers are increasingly required to make distinctions between citizens and non-citizens living along the border with Mexico.

White mass shooters receive sympathetic media treatment

White mass shooters receive much more sympathetic treatment in the media than black shooters, according to a new study that analyzed coverage of 219 attacks.

New study could hold key to hack-proof systems

Quantum Physics News - Tue, 07/17/2018 - 06:50
Major data breaches have made worldwide headlines of late but an international consortium of scientists—including a professor from Heriot-Watt—have developed a new technique that could result in hack-proof systems.

Sociologist uses Twitter to research criminological behavior online

Social Sciences News - Tue, 07/17/2018 - 06:32
In the modern era of social media, more than 300 million people use Twitter to share news and engage in online conversations. This provides a glimpse into the minds of a diverse public – making Twitter a useful tool for researchers to study people who sympathize and promote extreme violence.

Researchers work to advance understanding of hydrodynamic instabilities in NIF, astrophysics

General Physics - Tue, 07/17/2018 - 06:31
In a Proceedings of the National Academy of Sciences (PNAS) "Special Feature" paper published online June 26, Lawrence Livermore National Laboratory (LLNL) and University of Michigan researchers reported on recent experiments and techniques designed to improve understanding and control of hydrodynamic (fluid) instabilities in high energy density (HED) settings such as those that occur in inertial confinement fusion implosions on the National Ignition Facility (NIF).

"To be or not to be?" Hamlet asked aloud as he pondered the meaning of life.

Murder rates highest in countries that lack due process

Social Sciences News - Tue, 07/17/2018 - 06:20
Governments that do the best job protecting the rights of the accused have the lowest murder rates, while those that neglect due process have the highest, according to a five-year study of 89 countries by CU Boulder political scientists.

What happens when we heat the atomic lattice of a magnet all of a sudden?

General Physics - Tue, 07/17/2018 - 05:35
Magnets have fascinated humans for several thousand years and enabled the age of digital data storage. They occur in various flavors. Ferrimagnets form the largest class of magnets and consist of two types of atoms. Similar to a compass needle, each atom exhibits a little magnetic moment, also called spin, which arises from the rotation of the atom's electrons about their own axes. In a ferrimagnet, the magnetic moments point in opposite directions for the two types of atoms (see panel A). Thus, the total magnetization is the sum of all magnetic moments of type 1 (M1) (blue arrows) and type 2 (M2) (green arrows). Due to the opposite direction, the magnitude of the total magnetization is M1-M2.

A step closer to quantum computers: Researchers show how to directly observe quantum spin effects

Quantum Physics News - Tue, 07/17/2018 - 05:23
With companies like Google, Microsoft and IBM all racing to create the world's first practical quantum computer, scientists worldwide are exploring the potential materials that could be used to build them. Now, Associate Professor Yang Hyunsoo and his team from the Department of Electrical and Computer Engineering at the National University of Singapore (NUS) Faculty of Engineering have demonstrated a new method which could be used to bring quantum computing closer to reality.
