Research letter: Viewers ate more while watching Hollywood action flick on TV

Television shows filled with action and sound may be bad for your waistline. TV viewers ate more M&Ms, cookies, carrots and grapes while watching an excerpt from a Hollywood action film than those watching an interview program.

Scientists call for investigation of mysterious cloud-like collections in cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don't know what they do --...

Scientists develop 'electronic nose' for rapid detection of C. diff infection

This image depicts from lef to right Dr Martha Clokie, Professor Andy Ellis and Professor Paul Monks from the University of Leicester with the mass spectrometerA fast-sensitive "electronic-nose" for sniffing the highly infectious bacteria C-diff, that causes diarrhea, temperature and stomach cramps, has been developed by a team at the University of Leicester.

Memory in silent neurons

When we learn, we associate a sensory experience either with other stimuli or with a certain type of behaviour. The neurons in the cerebral cortex that transmit the information modify...

Reducing water scarcity possible by 2050

This map shows regional feasibility of strategies to reduce water stress. In most basins under stress, at least five of the six strategies could be applied.Water scarcity is not a problem just for the developing world. In California, legislators are currently proposing a $7.5 billion emergency water plan to their voters; and U.S. federal officials...

Managing coasts under threat from climate change and sea-level rise

Coastal regions under threat from climate change and sea-level rise need to tackle the more immediate threats of human-led and other non-climatic changes, according to a team of international scientists.

Argonne scientists pioneer strategy for creating new materials

Making something new is never easy. Scientists constantly theorize about new materials, but when the material is manufactured it doesn't always work as expected. To create a new strategy for...

After Great Recession, Americans are unhappy, worried, pessimistic, Rutgers study finds

The protracted and uneven recovery from the Great Recession has led most Americans to conclude that the U.S. economy has undergone a permanent change for the worse, according to a...

Plug n' play protein crystals

These are virus-avidin nanoparticle crystal structures.Almost a hundred years ago in 1929 Linus Pauling presented the famous Pauling's Rules to describe the principles governing the structure of complex ionic crystals. These rules essentially describe how...

Flapping baby birds give clues to origin of flight

A nine day-old chukar chick is righting itself using asymmetric wing flapping and rolling after being dropped upside down.How did the earliest birds take wing? Did they fall from trees and learn to flap their forelimbs to avoid crashing? Or did they run along the ground and pump...

New research reveals how wild rabbits were genetically transformed into tame rabbits

The genetic changes that transformed wild animals into domesticated forms have long been a mystery. An international team of scientists has now made a breakthrough by showing that many genes...

Nature's tiny engineers

Conventional wisdom has long held that corals -- whose calcium-carbonate skeletons form the foundation of coral reefs -- are passive organisms that rely entirely on ocean currents to deliver dissolved substances, such as nutrients and oxygen. But now scientists at...

Zooming in for a safe flight

As nocturnal animals, bats are perfectly adapted to a life without light. They emit echolocation sounds and use the delay between the reflected echoes to measure distance to obstacles or...

Why plants in the office make us more productive

'Green' offices with plants make staff happier and more productive than 'lean' designs stripped of greenery, new research shows.

Antarctic sea-level rising faster than global rate

Icicles are formed by the melting of a glacier in west Antarctica. The melt here is rapid and has been accelerating, injecting greater quantities of freshwater into the ocean and raising sea levels.A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by...

Not all phytoplankton in the ocean need to take their vitamins

This is <i>Emiliana huxleyi</i>, a marine phytoplankton whose blooms can grow so large they are visible from space. The researchers found it does not require vitamin B1 to grow, as previously thought.Some species of marine phytoplankton, such as the prolific bloomer Emiliania huxleyi, can grow without consuming vitamin B1 (thiamine), researchers have discovered. The finding contradicts the common view that E....

Factor in naked mole rat's cells enhances protein integrity

The naked mole rat, a long-lived rodent, is being studied for the secrets its biology can reveal about healthy aging.  Investigators at The University of Texas Health Science Center at San Antonio found a factor in the rodent's cells that protects and alters function of the proteasome, a garbage disposer for damaged and obsolete proteins.Scientists at the Barshop Institute for Longevity and Aging Studies, part of the School of Medicine at the UT Health Science Center at San Antonio, have found another secret of...

Prions can trigger 'stuck' wine fermentations, researchers find

A chronic problem in winemaking is "stuck fermentation," when yeast that should be busily converting grape sugar into alcohol and carbon dioxide prematurely shuts down, leaving the remaining sugar to...

Astrophysicists report radioactive cobalt in supernova explosion

A radioactive decay chain and the spectrum obtained by the INTEGRAL observatory. Note the scale of the vertical axis -- about one gamma quantum an hour per 1cm2!A group of astrophysicists, including researchers from MIPT, has detected the formation of radioactive cobalt during a supernova explosion, lending credence to a corresponding theory of supernova explosions. Details are...

Breakthrough in light sources for new quantum technology

This is an illustration of the single-photon cannon. A quantum dot (illustrated with the yellow symbol) emits one photon (red wave packet) at a time. The quantum dot is embedded in a photonic-crystal structure, which is obtained by etching holes (black circles) in a semiconducting material (light grey). Due to the holes, the photons are not emitted in all directions, but only along the channel where there are no holes. Only 1.6 percent of the emitted photons will be emitted in other directions (illustrated by the upward moving photon) and is thus lost, while 98.4 percent are emitted in the desired direction.Electronic circuits are based on electrons, but one of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons. First,...

Radio telescopes settle controversy over distance to Pleiades

Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster -- a controversy that posed a potential challenge to...
