Aversion to Clashing Harmonies is Due to Mathematical Relationships of Overtones

headphones-music-kid

There are many people who dislike clashing dissonances of some modernist composers. It’s been long thought that dissonant musical chords contain acoustic frequencies that interfere with another, disturbing people. Now, a new study indicates that humans prefer consonant chords because of the mathematical relationship between the many different frequencies that make up the sounds. The […]

Chimps and Humans Harbor Similar Gut Enterotypes

humans and chimpanzees share the same three distinct communities of bacteria in their guts

A team of scientists have discovered that humans and chimpanzees share the same three distinct communities of bacteria in their guts. In the last few years, scientists have made great inroads in understanding the crucial interactive role gut bacteria play in harvesting nutrients, assisting immune systems, and protecting the host against pathogens. Now Yale University […]

Fungal Meningitis Has New Appetite for Human Brains

Meningitis-Outbreak

In the USA, an ongoing fungal meningitis outbreak has killed 30 people and sickened another 419. The fungus responsible has never wrecked such havoc before. Exserohilum rostratum is a plant-eating generalist fungus that has a spore-launching mechanism ideal for airborne infection. It is usually found in grasses, but it will dine on anything, including humans. […]

A Single Hydrogen Molecule Vibrates Macro Object

quartz-tuning-fork

Physicists have demonstrated that a hydrogen molecule dancing between two possible positions can induce regular vibration of a nearby cantilever, creating a miniature tuning fork made up of quartz. The scientists published their findings in the journal Science. A single molecule has never been shown to be able to move something on a macroscopic scale, […]

Zombie-Ant Fungus Faces its Own Deadly, Specialized Parasites

hyperparasite-zombie-fungus

The zombie-ant fungus is part of the Ophiocordyceps genus, and its strange way of infecting worker ants’ heads and controlling them to distribute more spores has been well documented in scientific literature. Fossil evidence suggests that this infection has been occurring for at least 48 million years. Research seems to indicate that different species of […]

Scientists Use Quasars to Probe Dark Energy & Measure its Role in the Evolution of the Universe

Scientists Use Quasars to Probe Dark Energy & Measure its Role in the Eevolution of the Universe

An international team of scientists are measuring the role of dark energy in the evolution of the universe by using a new mapping technique that uses quasars to probe dark energy over 10 billion years in the past. BOSS, the Baryon Oscillation Spectroscopic Survey, is mapping a huge volume of space to measure the role […]

Neural Connection Between Infant Stress & Depressions in Teenage Girls

depressed-girl-infant

Stressful experiences in the first year of life can drive hormonal changes in girls later in childhood. These chemical changes lead to abnormal brain connectivity, signs of anxiety and depression at age 18. The researchers published their findings in the journal Nature Neuroscience. Stress in early life is a risk factor for a large variety […]

In a newly published study, a team of scientists report the results of their theoretical models of the behavior of interstellar dust grains as the Sun moves through space. The space between stars is not empty. It contains copious but diffuse amounts of gas and dust; in fact about 5-10% of the total mass of […]

Corals Emit Chemical Alarm to Summon Friendly Fish When Attacked

gobiodon-histrio-coral

When Acropora nasuta corals come into contact with the toxic seaweed Chlorodesmis fastigiata, they emit a chemical that summons gobies, inch-long fish live in the crevices and crannies of the coral. The scientists published their findings in the journal Science. They were able to summon gobies within minutes of the contact of seaweed. The researchers […]
