To Predict a Bird’s Song, Head Out to Space
by Andrew Porterfield in United Academics
Any given species of bird probably has a variety of different songs. Most bird studies track individual birds in their own habitats, and then make more or less one-by-one comparisons—a bird in a forest will sound different from the same species in a city. An international team has taken these studies one step further—by making a giant leap into space.... Read more »

Getting Science Right: Power Cables and Cancer
by Katja Keuchenius in United Academics
Some people would think twice before buying a house next to high-voltage power line. Wasn’t there something in the news about these wires causing cancer? Indeed many media have elaborately cited people worrying about the risks of electricity. But often without offering a scientific view on the subject.... Read more »

A Quantum Version of Google
by Carian Thus in United Academics
A team of computer scientists in Spain applied a quantum PageRank algorithm to a network with 7 webpages. They found that the quantum PageRank sometimes ordered the webpages differently in terms of importance, but averaging the quantum PageRank score over time recovered the classical ordering....

Boosting your wage by lowering your voice
by Katja Keuchenius in United Academics
t’s sexier, we already knew that. But lower voices do more than just turning people on. It appears a deep sound also means more success in your career. A new study makes some pretty clear statements about the associations between wage, management power, tenure and the tone of voice.... Read more »

Looking Into The Personality of Adventurers
by Katja Keuchenius in United Academics
Some feel the need to explore more than others. This apparently random characteristic really makes a difference to personalities, a mice experiment shows. Those that like to be adventurous and have the capacity to do so, develop different brains than those who stay mostly in the same place.... Read more »

Music and Cannabis; What’s the Connection?
by Mark Fonseca Rendeiro in United Academics
When you bring up the subject of listening to music while stoned, you get a range of responses, almost all of them positive. While you might enjoy a song in a non-altered state, under the influence of Cannabis, it has been established that listening to and creating music is somehow a deeper and more intense experience. The disputed issue that arises is why this happens and if the feeling is real.... Read more »

The Benefits Of Being ill
by Katja Keuchenius in United Academics

It’s Not the Sugar That Rots Teeth
by Andrew Porterfield in United Academics
You’ve been hearing it for years; don’t eat too much sugar, because sugar rots your teeth. It turns out that sugar isn’t the real culprit behind tooth decay. Researchers, looking at the bacteria responsible for dental cavities, had found a molecule that can stop these common dental problems.
Jose Cordova, a Yale University researcher, and Erich Astudillo, from the University of Chile, identified the new molecule, called Keep32, that kills the Streptococcus Mutans bacteria an........ Read more »

Is it impossible to drown yourself?
by Anouk Vleugels in United Academics
Kind of a morbid question, but apparently one that is on many people’s minds. Suicide by drowning is definitely not impossible, although it is not the easiest method. Due to the body’s natural tendency to come up for air, drowning attempts are most likely to succeed in deep waters.... Read more »

Taking Two Antibiotics for Quick Recovery?
by Geetanjali Yadav in United Academics
