Dubstep Music Found To Protect Against Mosquito Bites, Says Study (bbc.com)
According to a new study published in the journal Acta Tropica, listening to electronic music -- specifically dubstep, produced by U.S. artist Skrillex -- could protect against mosquito bites. The BBC reports:
Sound is "crucial for reproduction, survival, and population maintenance of
many animals," says a team of international scientists specializing in mosquitoes and the diseases they carry. They subjected adults of the species Aedes aegypti, known as the yellow fever mosquito, to electronic music to see whether it could work as a repellent. Scary Monsters And Nice Sprites, a track by Skrillex which features on his Grammy-award winning album of the same name, was chosen because of its mix of very high and very low frequencies.
"In insects, low-frequency vibrations facilitate sexual interactions, whereas noise disrupts the perception of signals from conspecifics [members of the same species] and hosts," the scientists said. Female adult mosquitoes were "entertained" by the track and attacked hosts later and less often than those in a dubstep-free environment. Scientists said "the occurrence of blood feeding activity was lower when music was being played." The scientists also found that mosquitoes exposed to the song had sex "far less often" than mosquitoes without music. "The observation that such music can delay host attack, reduce blood feeding, and disrupt mating provides new avenues for the development of music-based personal protective and control measures against Aedes-borne diseases." |

Just as our ancient ancestors drew animals on cave walls and carved animals from wood and bone, we decorate our homes with animal prints and motifs, give our children stuffed animals to clutch, cartoon animals to watch, animal stories to read. |

Were I called on to define, very briefly, the term Art, I should call it 'the reproduction of what the Senses perceive in Nature through the veil of the soul.' The mere imitation, however accurate, of what is in Nature, entitles no man to the sacred name of 'Artist.' |

The object of a New Year is not that we should have a new year. It is that we should have a new soul and a new nose; new feet, a new backbone, new ears, and new eyes. Unless a particular man made New Year resolutions, he would make no resolutions. Unless a man starts afresh about things, he will certainly do nothing effective. |

Part of the joy of music is listening to lots of different kinds of music and learning from it. Specifically for me, I like writing songs that move me, and what moves me are beautiful songs on the piano or the guitar and really, really heavy music. |

Music as background to me becomes like a mosquito, an insect. In the studio we have big speakers, and to me that's the way music should be listened to. When I listen to music, I want to just listen to music. |

As a scholar, you don't want to repeat yourself, ever. You're supposed to say it once, publish it, and then it's published, and you don't say it again. If someone comes and gives a scholarly paper about something they've already published, that's just terrible. As a university president, you have to say the same thing over and over and over. |

If you are the record label who owns Lady Gaga, and you have a new artist coming up, you can say, 'Let's have the artist play just before Gaga.' Now you've exposed the huge Gaga audience to the new artist. It's similar to showing a trailer before a movie. The hit creates a hit. |

I could count my modeling jobs on my hands and toes. When I graduated from college, I moved to New York specifically to study acting, and I needed to pay the bills, and it's better to make a couple thousand dollars in one day than to wait tables six days a week. |

Sleep Deprivation Disrupts Brain-Cell Communication, Study Finds (npr.org)
A new study published in the journal Nature Medicine found that sleep deprivation causes the bursts of electrical activity that brain cells use to communicate to become slower and weaker. "The finding could help explain why a lack of sleep impairs a range of mental functions, says Dr. Itzhak Fried, an author of the study and a professor of neurosurgery at the University of California, Los Angeles," reports NPR. From the report:
The finding comes from an unusual study of patients being evaluated for surgery to correct severe epilepsy. As part of the evaluation, doctors place wires in the brain to find out where a pat...

How Diet May Have Changed the Way Humans Speak
"Ancient hunter-gathererers often had front teeth that met together, unlike today's more common alignment where the upper front teeth 'overbite' the lower front teeth," writes Slashdot reader omfglearntoplay. "This malocclusion is a result of changes to the ancestral human diet and introduction of soft foods, according to a new study published in the journal Science." ABC News reports:
More than 2,000 different sounds exist across the roughly 7,000 to 8,000 languages that humans speak today, from ubiquitous cardinal vowels such as "a" and "i" to the rare click consonants found in southern Africa. Scientists had long thought this range of soun...

Microplastics Found In 90 Percent of Table Salt (nationalgeographic.com)
New research shows microplastics in 90 percent of the table salt brands sampled worldwide. Of 39 salt brands tested, 36 had microplastics in them, according to a new analysis by researchers in South Korea and Greenpeace East Asia. Salt samples from 21 countries in Europe, North and South America, Africa, and Asia were analyzed. The three brands that did not contain microplastics are from Taiwan (refined sea salt), China (refined rock salt), and France (unrefined sea salt produced by solar evaporation). The study was published this month in the journal Environmental Science & Technology.

As a cell biologist, Sundar Balasubramanian never forgot his rural southern Indian roots, or the traditional practices his uncle, the village healer, exposed him to. Today, as a researcher and assistant professor at the Medical University of South Carolina, Balasubramanian has turned his focus back to those roots — specifically, to pranayama, a deep-breathing relaxation technique. He’s showing that this ancient yoga practice is about more than relaxing — it can change us at the cellular level.
Q: What made you examine this technique through a cellular biology lens?
A: In 2005, I noticed whi...

Fasting Can Improve Overall Health By Causing Circadian Clocks In the Liver and Skeletal Muscle To Rewire Their Metabolism, Study Finds (sciencedaily.com)
In a University of California, Irvine-led study, researchers found evidence that fasting affects circadian clocks in the liver and skeletal muscle, causing them to rewire their metabolism, which can ultimately lead to improved health and protection against aging-associated diseases. The study was published recently in Cell Reports. The research was conducted using mice, which were subjected to 24-hour periods of fasting. While fasting, researchers noted the mice exhibited a reduction in oxygen consumption (VO2), respiratory exchange ratio (RER), and energy expenditure, all of which were completely abolished by refeeding, which parallel...

Scientists Discover a Game-Changing Way To Remove Salt From Water
[T]he ability to quickly and easily desalinate water has long been a goal of scientists around the world. And now, a group of researchers from Columbia University believe they've found a way to do it. The process is called Temperature Swing Solvent Extraction (TSSE) and it's designed to purify hypersaline brines (water that contains a high concentration of salts, making it up to seven times as salty as seawater). This kind of waste water is produced by industrial processes and during oil and gas production and it poses a major pollution risk to groundwater.

Honeybees Seem To Understand the Notion of Zero, Study Finds
A new study published in the journal Science finds honeybees are able to understand the concept of zero numerosity, joining the ranks of dolphins, parrots, and primates. Sci-News.com reports:
The study authors set out to test the honeybee on its understanding, marking individual honeybees for easy identification and luring them to a specially-designed testing apparatus. The bees were trained to choose an image with the lowest number of elements in order to receive a reward of sugar solution. For example, the bees learned to choose three elements when presented with three vs. four; or two elements when presented with two vs. thre...

'Great Dying': Rapid Warming Caused Largest Extinction Event Ever, Report Says (theguardian.com)
Rapid global warming caused the largest extinction event in the Earth's history, which wiped out the vast majority of marine and terrestrial animals on the planet, scientists have found. The mass extinction, known as the "great dying," occurred around 252m years ago and marked the end of the Permian geologic period. The study of sediments and fossilized creatures show the event was the single greatest calamity ever to befall life on Earth, eclipsing even the extinction of the dinosaurs 65m years ago. Up to 96% of all marine species perished while more than two-thirds of terrestrial species disappeared. The cataclysm was so severe it wiped out most of the planet's trees, insects, plants, liza...

Algorithmic Analysis Shows That Pop Music Is Sadder and Angrier Than Ever
BBC Culture reports -- with some neat graphs in the article -- on two different scientific studies that both found that chart-topping pop music has been getting steadily sadder and angrier since the 1950s, and that both song lyrics and the musical tone in hit songs are sadder, more fearful, and angrier than ever before in history. Lior Shamir of Lawrence Technical University found the following trends in his algorithmic analysis of Billboard Hot 100 hit song lyrics: "Expressions of anger and disgust roughly doubled over those 65 years, for instance, while fear increased by more than 50%. Remarkably, today's songs are even more aggressive and fearful than in punk's heyday. One probable reason for this is the growin...
