BLOOMINGTON, Ind. -- Despite efforts by ridesharing companies to eliminate or reduce discrimination, research from the Indiana University Kelley School of Business finds that racial and LGBT bias persists among drivers.

An article published today in the Annals of Internal Medicine reports that 25 million dwellings that house 81 million Americans lack adequate space or plumbing to allow compliance with recommendations that a person who may have COVID-19 maintain physical separation from others in their household.

FINDINGS

Researchers at the UCLA Jonsson Comprehensive Cancer Center and UCLA School of Dentistry have identified a potential new combination therapy to treat advanced head and neck squamous cell carcinoma, the most common type of head and neck cancer.

WASHINGTON, July 21, 2020 -- Twitter mentions show distinct community structure patterns resulting from communication preferences of individuals affected by physical distance between users and commonalities, such as shared language and history.

In a new study, researchers have compared diseased colon with healthy tissue to better understand how inflammatory bowel disease (IBD) is linked to an increased risk of colorectal cancers, at a molecular level. Researchers from the Wellcome Sanger Institute and Cambridge University Hospitals found that the rate of DNA change within colon cells affected by IBD was more than double that in healthy colon, increasing the likelihood of these cells gaining DNA changes that could lead to cancer.

WASHINGTON, July 21, 2020 -- Episodes of social unrest rippled throughout Chile in 2019 and disrupted the daily routines of many citizens. Researchers specializing in economics, mathematics and physics in Chile and the U.K. banded together to explore the surprising social dynamics people were experiencing.

To do this, they combined well-known epidemic models with tools from the physics of chaos and interpreted their findings through the lens of social science as economics.

Tailoring and manipulating electromagnetic wave propagation has been of great interest within the scientific community for many decades. In this context, wave propagation have been engineered by properly introducing spatial inhomogeneities along the path where the wave is traveling. Antennas and communications systems in general have greatly benefited from this wave-matter control.

The MIR range of the electromagnetic spectrum, which roughly covers light in the wavelength regime between 3 to 10 micrometers, coincides with the energies of fundamental molecular vibrations. Utilizing this light for the purpose of imaging can produce stills with chemical specificity, i.e. images with contrast derived from the chemical composition of the sample. Unfortunately, detecting MIR light is not as simple as detecting light in the visible regime. Current MIR cameras exhibit excellent sensitivity but are very sensitive to thermal noise.

The activation of the immune system could eventually perpetuate some of the deleterious effects of alcohol, like addiction. It is the conclusion of a research carried out by an international team led by Dr. Santiago Canals, from the Institute of Neurosciences in Alicante (Spain), a joint center of the Spanish National Research Council and the University Miguel Hernández in Elche, and Dr. Wolfgang Sommer, from the Central Institute of Mental Health of the University of Heidelberg (Germany).

Developing expertise usually requires a variety of skills, and some people can become experts while others can't. Common practice in perceptual learning research has treated ubiquitous individual learning differences as random fluctuations or noise and made inferences based on aggregated data from multiple subjects.

Recent research, however, is paying more attention to individual learning differences.

A team of researchers led by the University of Adelaide and University of Stuttgart has used 3D micro-printing to develop the world's smallest, flexible scope for looking inside blood vessels.

The camera-like imaging device can be inserted into blood vessels to provide high quality 3D images to help scientists better understand the causes of heart attack and heart disease progression, and could lead to improved treatment and prevention.

Topological photonics underpins a promising paradigm for robust light manipulation and smart design of optical devices with improved reliability and advanced functionalities governed by the nontrivial band topology. Nanostructures made of high-index dielectric materials with judiciously designed resonant elements and lattice arrangements show special promise for implementation of topological order for light at the nanoscale and optical on-chip applications.

Tsukuba, Japan - Age shows nowhere better than on the skin. The ravages of time on skin and the epidermal stem cells that differentiate to replenish its outer layer have been hypothesized, but there has been no method to evaluate their aging at the molecular level. Now, researchers at the University of Tsukuba and the National Institute of Advanced Industrial Science and Technology (AIST) have revealed that changes in the complex sugars called glycans that coat the surface of epidermal stem cells can serve as a potential biological marker of aging.

Scientists searching for better diagnostic tests, drugs or vaccines against a virus must all begin by deciphering the structure of that virus. And when the virus in question is highly pathogenic, investigating, testing or developing these can be quite dangerous. Prof. Roy Bar-Ziv, Staff Scientist Dr. Shirley Shulman Daube, Dr. Ohad Vonshak, a former research student in Bar-Ziv's lab, and current research student Yiftach Divon have an original solution to this obstacle. They demonstrated the production of viral parts within artificial cells.

Scientists of Tomsk Polytechnic University jointly with teams from the University of Chemistry and Technology, Prague and Jan Evangelista Purkyn? University in Ústí nad Labem have developed a new 2D material to produce hydrogen, which is the basis of alternative energy. The material efficiently generates hydrogen molecules from fresh, salt, and polluted water by exposure to sunlight. The results are published in ACS Applied Materials & Interfaces (IF: 8,758; Q1).
