Is a foreign-sounding name a disadvantage?
2023-06-29
Sports are a way in for people who want to build contacts with other people. Sports give you an opportunity to integrate and interact with people on an equal footing. For immigrants, sports can be the key that allows them to fit into a society.
But how easy is it for people with strange names to join in the fun?
That depends on how foreign sounding a person’s name is, and perhaps where the person lives. Because the results from the experiment were not the same throughout Scandinavia. Some are more similar than others.
The rigged football experiment actually shows encouraging ...
No more crying over rotting onions? Researchers gain insight into bacteria threatening Vidalia onion production
2023-06-29
The Vidalia onion is a trademarked variety of sweet onion that can only be grown in several counties in Georgia by law. These prized vegetables are currently threatened by the bacterial pathogen Pantoea ananatis, which severely damages the plant by rotting the onion bulbs and leaves. This results in substantial losses for onion growers in Georgia, as there are no disease resistant cultivars available. The plant toxin pantaphos, produced by the P. ananatis pathogen, causes the rotting symptoms in onion. More specifically, the eleven genes responsible ...
US infant mortality declined, but low birth weight, preterm births increased
2023-06-29
Nearly 4 million infants are born in the United States each year. Despite improvements in obstetric and perinatal care, infant mortality in the U.S. is of ongoing concern. The nation ranks No. 23 in the world for infant mortality rates with 5.4 deaths per 1,000 live births, with worse outcomes observed in Black infants compared to white infants.
Now, new original research from Florida Atlantic University’s Schmidt College of Medicine and collaborators indicates that infant mortality alone may be insufficient as a health indicator. For the study, researchers explored time trends and racial inequities ...

Researchers on UN Maritime Organization: "At the moment, it’s working against its own green transition"
2023-06-29
The UN’s International Maritime Organization (IMO) is actively contributing to the shipping industry being far off course from ever reaching its climate goals. In large part, this is because the organization lacks funding and expertise. Without strengthening the IMO, any transition of the enormous industry is hazily imaginable. This, according to the Copenhagen and Lund university researchers behind a new study of the organization.
Three percent of the world's total greenhouse gas emissions is attributable to the shipping industry. And things remain headed in the wrong direction – with CO2 emissions from ships continuing to rise year after year. This has increased ...
Secret of stem cells protecting the gastric mucosa
2023-06-29
Ikoma, Japan – The gastric corpus, which is a major component of the glandular stomach, is composed of parietal, chief, pit, and neck cells. Each of these specialized epithelial cells play an important role in digestion, and they are continuously replenished by new ones which are formed via the differentiation of stem cells. Defects in this process lead to gastric diseases such as intestinal metaplasia and gastric cancer. However, the underlying mechanisms responsible for the renewal and differentiation of stem cells, and ...
Higher average temperature linked to serious vision impairment among older Americans
2023-06-29
TORONTO, ON – American adults 65 years old and older living in warmer regions are more likely to have serious vision impairment than their peers living in cooler regions, according to a recent study published in the journal Ophthalmic Epidemiology.
Compared to those who lived in counties with average temperature of less than 50°F (< 10 °C), the odds of severe vision impairment were 14% higher for those who lived in counties with average temperature between 50-54.99°F, 24% higher for those between ...

Scientists find evidence for slow-rolling sea of gravitational waves
2023-06-29
Scientists are reporting the first evidence that our Earth and the universe around us are awash in a background of spacetime undulations called gravitational waves. The waves oscillate very slowly over years and even decades and are thought to originate primarily from pairs of supermassive black holes leisurely spiraling together before they merge.
The findings, reported in a series of papers in The Astrophysical Journal Letters, come from 15 years’ worth of observations made ...
First misinformation susceptibility test finds ‘very online’ Gen Z and millennials are most vulnerable to fake news
2023-06-29
University of Cambridge psychologists have developed the first validated “misinformation susceptibility test”: a quick two-minute quiz that gives a solid indication of how vulnerable a person is to being duped by the kind of fabricated news that floods online spaces.
The test, proven to work through a series of experiments involving over 8,000 participants taking place over two years, has been deployed by polling organisation YouGov to determine how susceptible Americans are to fake headlines.
The first survey to use the new 20-point test, called ‘MIST’ ...
Clamor of gravitational waves from universe’s merging supermassive black holes ‘heard’ for first time
2023-06-29
Following 15 years of data collection in a galaxy-sized experiment, scientists have “heard” the perpetual chorus of gravitational waves rippling through our universe for the first time — and it’s louder than expected.
The groundbreaking discovery was made by scientists with the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) who closely observed stars called pulsars that act as celestial metronomes. The newly detected gravitational waves — ripples in the fabric of space-time — are by far the most powerful ever measured: They carry roughly a million times as much energy as ...
Gravitational waves from colossal black holes found using 'cosmic clocks'
2023-06-29
You can't see or feel it, but everything around you — including your own body — is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy, according to a new study by a team of researchers with the U.S. National Science Foundation's NANOGrav Physics Frontiers Center.
The findings published today in The Astrophysical Journal Letters are from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), a collaborative team of researchers from more than 50 institutions in the U.S. and abroad. The team ...
