New research discovers the emergence of Twitter 'tribes'

2013-03-14
(Press-News.org) A project led by scientists from Royal Holloway University in collaboration with Princeton University, has found evidence of how people form into tribe-like communities on social network sites such as Twitter.

In a paper published in EPJ Data Science, they found that these communities have a common character, occupation or interest and have developed their own distinctive languages.

"This means that by looking at the language someone uses, it is possible to predict which community he or she is likely to belong to, with up to 80% accuracy," said Dr John Bryden from the School of Biological Sciences at Royal Holloway. "We searched for unusual words that are used a lot by one community, but relatively infrequently by the others. For example, one community often mentioned Justin Bieber, while another talked about President Obama."

Professor Vincent Jansen from Royal Holloway added: "Interestingly, just as people have varying regional accents, we also found that communities would misspell words in different ways. The Justin Bieber fans have a habit of ending words in 'ee', as in 'pleasee', while school teachers tend to use long words."

The team produced a map of the communities showing how they have vocations, politics, ethnicities and hobbies in common. In order to do this, they focused on the sending of publically available messages via Twitter, which meant that they could record conversations between two or many participants.

To group these users into communities, they turned to cutting-edge algorithms from physics and network science. The algorithms worked by looking for individuals that tend to send messages to other members of the same community.

Dr Bryden then suggested analysing the language use of these discovered communities.

Dr Sebastian Funk from Princeton University said: "When we started to apply John's ideas, surprising groups started to emerge that we weren't expecting. One 'anipals' group was interested in hosting parties to raise funds for animal welfare, while another was a fascinating growing community interested in the concept of gratitude."

### Notes to editors:

The paper "Word usage mirrors community structure in the online social network Twitter" is available from: http://www.epjdatascience.com/content/2/1/3

Royal Holloway has filed a patent application in order to protect many of the techniques described in the paper.

What do American bullfrogs eat when theyre away from home? Practically everything!
2013-03-14
American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems. In the largest study of its kind to date, the stomach contents of over 5,000 invasive alien American bullfrogs from 60 lakes and ponds on southern Vancouver Island were examined to identify the native and exotic animals that they had preyed upon. The study was published in the open access journal NeoBiota. Over ...

The mysterious GRIN3A and the cause of schizophrenia

2013-03-14
Philadelphia, PA, March 14, 2013 – Since the 1960s, psychiatrists have been hunting for substances made by the body that might accumulate in abnormally high levels to produce the symptoms associated with schizophrenia. In particular, there was a search for chemicals that might be related to the hallucinogens phencyclidine (PCP) or lysergic acid diethylamide (LSD), which could explain the emergence of psychotic symptoms in schizophrenia. This "auto-intoxication" hypothesis led investigators on a wild goose chase where substances, including the "Pink Spot" and the "Frohman ...

Testing can improve learning among young and old people

2013-03-14
Testing can improve learning among young and old people alike, according to new research from Rice University. The study found that regardless of their age, intelligence or whether they work or attend college, people appear to learn more by taking tests rather than merely rereading or studying information. The research was published in the March 2013 edition of Psychology and Aging. "There is a significant body of research examining the benefits of testing among young students," said Ashley Meyer '09, the study's lead author. Currently a cognitivepsychologist with the ...

Hovering is a bother for bees: Fast flight is more stable

2013-03-14
Amsterdam, March 14, 2013 - Bumblebees are much more unstable when they hover than when they fly fast, according to new research published this month in the Journal of Theoretical Biology. The authors of the paper, Na Xu and Mao Sun from Beijing University of Aeronautics & Astronautics in China, used a mathematical model to analyze the way bumblebees fly at different speeds, showing that the bumblebee is unstable when it hovers and flies slowly, and becomes neutral or weakly stable at medium and high flight speeds. The instability at hovering and low speed is mainly ...

Smoking linked with worse urothelial cancer prognosis in patients, especially women

2013-03-14
Smoking significantly increases individuals' risk of developing serious forms of urothelial carcinoma and a higher likelihood of dying from the disease, particularly for women. That is the conclusion of a recent study published in BJU International. While the biological mechanisms underlying this gender difference are unknown, the findings indicate that clinicians and society in general should focus on smoking prevention and cessation to safeguard against deadly cancers of the bladder, ureters, and renal pelvis, especially in females. To evaluate the gender-specific effects ...

A better understanding of the impacts of grazing sheep

2013-03-14
This press release is available in Spanish. A U.S. Department of Agriculture (USDA) scientist is giving guidance to growers in Montana and the Dakotas on how grazing sheep when fields are left fallow will affect soil quality. Grazing sheep and other livestock was once common in the region before fertilizers were introduced in the 1950s. While fertilizers increased yields, they also have increased nitrogen runoff and leaching, made soils more acidic, and contributed to greenhouse gas emissions, according to Upendra Sainju, a soil scientist with the Agricultural Research ...

A new method for measuring the flow of traffic a street has to bear by measuring atmospheric noise

A new method for measuring the flow of traffic a street has to bear by measuring atmospheric noise
2013-03-14
Researchers from the University of Granada and the Carlos III University of Madrid have patented a new method to measure the flow of motorized traffic that a specific street carries each day, by measuring solely the levels of atmospheric noise. This pioneer system, unique in the world, is an alternative, or a complement, to other methods currently used to measure traffic flow, such as image counting or magnetic discharge levels. This method, designed by the University of Granada, allows a differentiation between the flow of cars, LGVs, HGVs and motorbikes/scooters along ...

Intense terahertz pulses cause DNA damage but also induce DNA repair

Intense terahertz pulses cause DNA damage but also induce DNA repair
2013-03-14
Terahertz (THz) radiation, a slice of the electromagnetic spectrum that occupies the middle ground between microwaves and infrared light, is rapidly finding important uses in medical diagnostics, security, and scientific research. As scientists and engineers find evermore practical uses for this form of radiation, questions persist about its potential human health risks. New research performed on lab-grown human skin suggests that short but powerful bursts of THz radiation may both cause DNA damage and increase the production of proteins that help the body fight cancer. ...

The beetle family Cerambycidae, also known as long-horned beetles or longicorns, is characterized by emblematic extremely long antennae, which are usually longer than the total body length of the animal. The family is rather rich in diversity with more than 20 000 species known, distributed worldwide. Some representatives of these bizarre-shaped beetles, are also known as serious pests with their wood-feeding larvae causing extensive damage to living trees or untreated lumber. The beetles from this family are mainly associated with leaf litter habitats, where the specimens ...
