Animals first flex their muscles
An unusual new fossil discovery of one of the earliest animals on earth may also provide the oldest evidence of muscle tissue – the bundles of cells that make movement in animals possible.
Aromatic compounds are found widely in natural resources such as petroleum and biomass, and breaking the carbon-carbon bonds in these compounds plays an important role in the production of fuels and valuable ...
Huge insect diversity revealed by genetic technologies
(Phys.org) —The diversity of plants, mammals and birds in Australia is well-known, but scientists have very little idea of how many hundreds of thousands of species of Australian insects exist.
Laser pulse turns glass into a metal
For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. This has been shown by calculations at the Vienna University of Technology. The effect ...
Researchers create global road maps showing potential economic and ecological consequences of new roads
Pacific plate shrinking as it cools: Calculations challenge assumptions about rigid lithosphere
The tectonic plate that dominates the Pacific "Ring of Fire" is not as rigid as many scientists assume, according to researchers at Rice University and the University of Nevada.
How the zebrafish gets its stripes
The zebrafish, a small fresh water fish, owes its name to a striking pattern of blue stripes alternating with golden stripes. Three major pigment cell types, black cells, reflective silvery cells, and yellow ...
Eta Carinae: Our Neighboring Superstars
(Phys.org) —The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the Sun, it ...
New research finds that world-class sprinters attack the ground to maximize impact forces and speed
The world's fastest sprinters have unique gait features that account for their ability to achieve fast speeds, according to two new studies from Southern Methodist University, Dallas.
Superabsorbing ring could make light work of snaps
A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create 'superabsorbing' systems to make the 'ultimate camera pixel'.
New scientific review investigates potential influences on recent UK winter floods
A comprehensive review of all potential factors behind the 2013/2014 UK winter floods is published today in the journal Nature Climate Change. The paper does not definitively answer whether human activity played ...
Optical microscope technique confirmed as valid nano-measurement tool
(Phys.org) —Recent experiments have confirmed that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional ...
Researchers find first direct evidence of 'spin symmetry' in atoms
Just as diamonds with perfect symmetry may be unusually brilliant jewels, the quantum world has a symmetrical splendor of high scientific value.
