Elephants imitate truck noises, other animals

Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for maintaining individual social relationships among animals that separate and reunite over time, like dolphins and whales, some bi...

Researchers quantify more noise in gene expression

Human identical twins have different fingerprints and march to the beat of subtly different phenotypes, an indication of heterogeneity which led bioengineering researchers at the University of California, San Diego (UCSD) to devised computer algorithms that identify the underlying sources of variation at the basic level of life: unscripted fluctuations within individual cells and variations betwe...

Noise And Delays Explain Why Some Genes Oscillate In Activity

If you snooze, you lose those uncomely grayish-brown crescents below your eyes. If you don't snooze, you lose a lot more. The body can't fight off infection, the muscles can't regenerate as quickly, the mind can't learn new words, and the eyes can't focus on the road. You also gain things: a bad mood and increased risk for diabetes, high blood pressure, and heart problems. Indeed, the effects of...

Phenotype is influenced by nature, nurture and noise

Unscripted biochemical variations, or noise, leads to oscillations in gene regulation that couldn't otherwise be predicted In a paper in Proceeding...

New dyslexia theory blames 'noise'

The dyslexic brain struggles to read because even small distractions can throw it off, according to a new model of dyslexia emerging from a group of recent studies. Instead, the studies suggest that children with dyslexia have bad filters f...

Noise tampers hearing

Like adults, children are likely to suffer hearing loss from continued exposure to loud noises like music, power generators, drilling machines and firecrackers, according to a new national survey. The survery says that 5 million children have noise-induced hearing loss in one or both ears. If the loss is only in one ear, the child's overall hearing is usually not affected, says Laura Sie...

Noise pollution can cause harm in cognitive development of children

Exposure to environmental stressors like noise can cause health problems// like cognitive impairment in children. Researchers across the world had conducted a cross-nation study to see the effect of pollutants like noise from the traffic and aircrafts on the health of the children. They had assessed the health of 2844 children in the age group of 9 to 10 years who attendee schools clos...

‘Loud Noise’ Research may help in Development of Prosthetics for Eldery

Apparently ‘Noise’ is not always a bad thing!! Researchers from the University of British Columbia have shown that // noise can at times help, rather than hinder, people's ability to sense things. It is not unusual to have an aversion for noise unless you are one of the modern age teenagers! The noise in India during Diwali can be deafening and there are now laws that allows only so m...

Preventing falls in elderly with noise

A new study by the researchers of University of British Columbia had showed that noise// might be not a hindrance but a help to our concentration and efficiency, more so when that is effectively used to help the older people maintain their balance. Noise is often thought as the one sensation that comes in our way of concentration on subjects we want to concentrate upon. Noise is often...

Pill might be able to reduce the damage loud noise does to your hearing

It's the latest wrinkle in research toward finding a pill that will help protect and even treat hearing loss from exposure to loud noise. While the effort is hardly new, experts say it has picked up steam in just the past few years.// Starting in a few months, a group of 600 Marines will face rifle training with not only foam plugs in their ears, but also a drink that tastes very much li...
