US cities segregated not just by where people live, but where they travel daily

2021-02-11
(Press-News.org) PROVIDENCE, R.I. [Brown University] -- One thing that decades of social science research has made abundantly clear? Americans in urban areas live in neighborhoods deeply segregated by race -- and they always have.

Less clear, however, is whether city-dwellers stay segregated when they leave home and go about their daily routines. That's a question to which Jennifer Candipan, an assistant professor of sociology at Brown University, was determined to find an answer.

By analyzing geotagged locations for more than 133 million tweets by 375,000 Twitter users in the 50 largest U.S. cities, Candipan and a team of researchers found that in most urban areas, people of different races don't just live in different neighborhoods -- they also eat, drink, shop, socialize and travel in different neighborhoods.

"Most of us can sense that segregation is about more than where people live -- it's also about how they move," Candipan said. "With the recent availability of data from global positioning systems, satellite imaging and social media, we've been able to start quantifying that segregated movement in cities. In combination with existing measures, we've been able to provide a fuller picture of racial inequality and segregation in America's cities."

Want to hire more women? Expand your short list

2021-02-11
ITHACA, N.Y. - As more male-dominated industries look for ways to hire women, new Cornell University research offers employers a simple solution - make your initial job candidate short list longer. Many professional advancement opportunities - jobs, promotions, trainings and mentorships - are filled through informal recruitment practices. But these practices pose an unintended barrier to gender diversity in male-dominant workplaces because when hiring managers consult their "mental Rolodex," they are more likely to associate certain jobs with specific genders. "Our research investigates informal short lists," said Brian Lucas, assistant ...

A new perceptually-consistent method for MSI visualization

A new perceptually-consistent method for MSI visualization
2021-02-11
Skoltech scientists have proposed a Mass Spectrometry Imaging (MSI) method leveraging the unique features of human vision. The research was published in the journal Analytical Chemistry. High-resolution mass spectrometry is an analytical technique that accurately measures the mass-to-charge ratio (m/z) of ions, produced from molecules by an ionization process, and the ion signal intensity (the relative number of ions). These measurements allow determining molecules' weights and structure, (by fragmenting them), thereby identifying various compounds, such as proteins, lipids, metabolites, ...

Rebuilding soil microbiomes in high-tunnel agricultural systems focus of study

Rebuilding soil microbiomes in high-tunnel agricultural systems focus of study
2021-02-11
The presence of high salt and nitrogen concentrations in high- tunnel soils may make it more challenging to rebuild a healthy soil microbiome following a soil-clearing event, according to microbial ecologists in Penn State's College of Agricultural Sciences. Their research findings have important implications for soil fertility, and by extension, crop health and yield, explained Laura Kaminsky, a doctoral candidate in plant pathology, who led the investigation under the guidance of Terrence Bell, assistant professor of phytobiomes. "Plants generally grow better with an active and diverse community of bacteria, fungi and other microbes in the soil," she said. "If these microbes are wiped out by a soil-clearing ...

A new strategy to destroy cancer cells using magnetic nanoparticles and fields

A new strategy to destroy cancer cells using magnetic nanoparticles and fields
2021-02-11
Scientists from Scientific and Educational Center «Smart Materials and Biomedical Applications» under the leadership of Kateryna Levada together with colleagues from Center for Immunology and Cellular Biotechnology of the Immanuel Kant Baltic Federal University conducted a joint interdisciplinary study on the development of a new method for treating leukemia using nanomaterials. The scientists analyzed how magnetic nanoparticles can be manipulated in in vitro conditions to achieve a selective antitumor effect. The method is based on the combined action of nanoparticles and permanent magnetic fields on human tumor cells. Leukemia ...

One dose of COVID-19 vaccine provokes strong immune response in those previously infected

2021-02-11
Although clinical trial data are encouraging, real-world evidence with regard to the COVID-19 vaccine remains scarce. In particular, response to the vaccine among those previously infected with SARS-CoV-2 is still not completely understood. Researchers from Bar-Ilan University and Ziv Medical Center now report preliminary evidence that people previously infected with the virus responded very strongly to one dose of the Pfizer vaccine, regardless of when they were infected and whether or not they had detectable antibodies against COVID-19 prior to receiving the vaccine. Their study, published on February 11, 2021 in the journal Eurosurveillance, was conducted on a cohort of 514 staff members at Ziv Medical Center. Seventeen ...

Hope for children with bow hunter syndrome

Hope for children with bow hunter syndrome
2021-02-11
DALLAS - Feb. 11, 2021 - Fusing the neck's top two vertebrae can prevent repeat strokes in children with bow hunter syndrome, a rare condition that affects a handful of U.S. pediatric patients each year, UT Southwestern researchers suggest in a recent study. The finding, published online in Child's Nervous System, offers a new way to treat these children and protect them from potentially lifelong neurological consequences. Bow hunter syndrome - so named because of the head's position when a person is shooting an arrow - is a condition affecting children and adults in which turning the head compresses blood vessels supplying the back of the brain from the vertebral artery. In adults, this condition ...

At least 50% of COVID-19 infections come from people who aren't showing symptoms

2021-02-11
A new study out of the University of Chicago has found that during the initial wave of the COVID-19 outbreak in New York City, only 1 in 5 to 1 in 7 cases of the virus was symptomatic. The research team found that non-symptomatic cases substantially contribute to community transmission, making up at least 50% of the driving force of SARS-CoV-2 infection. The results were published on Feb. 10 in the Proceedings of the National Academy of Sciences. When the COVID-19 epidemic arrived in the U.S., the investigators noticed that it was very difficult to estimate what proportion of people infected with SARS-CoV-2 would go on to develop symptoms, partially due to the initial challenges with testing capacity. "Without ...

Misuse of opioid drugs during pregnancy could have lasting impact on child's development

2021-02-11
As the number of pregnant women using opioid drugs continues to rise, questions have been raised about the long-term health effects on children exposed to these drugs in the womb. Researchers at the University of Maryland School of Medicine now have preliminary but striking evidence that suggests that such exposure can cause long-lasting impairment in the brain's ability to process sensory information. These impairments may give rise to autism, attention deficit hyperactivity disorder, and substance use disorders during adolescence. The landmark study, recently published in Journal ...
