The rainbow is not just colors - each color of light has its own frequency. The more frequencies you have, the higher the bandwidth for transmitting information.

Only using one color of light at a time on an electronic chip currently limits technologies based on sensing changes in scattered color, such as detecting viruses in blood samples, or processing airplane images of vegetation when monitoring fields or forests.

Researchers have shown how to shuttle lithium ions back and forth into the crystal structure of a quantum material, representing a new avenue for research and potential applications in batteries, "smart windows" and brain-inspired computers containing artificial synapses.

The research centers on a material called samarium nickelate, which is a quantum material, meaning its performance taps into quantum mechanical interactions. Samarium nickelate is in a class of quantum materials called strongly correlated electron systems, which have exotic electronic and magnetic properties.

Certain female mosquitoes quickly evolve more selective mating behavior when faced with existential threats from other invasive mosquito species, with concurrent changes to certain genetic regions, according to new research from North Carolina State University. The findings shed light on the genetics behind insect mating behavior and could have implications for controlling mosquito pests that plague humans.

ALBUQUERQUE, N.M. -- If you're ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid -- not drive, skid -- around the Earth's equator 500 times before wearing out the tread.

HOUSTON - (Aug. 16, 2018) - Anyone who has ever cursed a computer network as it slowed to a crawl will appreciate the remedy offered by scientists at Rice University.

Rice computer scientist Eugene Ng and his team say their solution will keep data on the fast track when failures inevitably happen.

Ng introduced ShareBackup, a strategy that would allow shared backup switches in data centers to take on network traffic within a fraction of a second after a software or hardware switch failure.

BINGHAMTON, N.Y. - A new manufacturing technique developed by researchers from Binghamton University, State University at New York may be able to avoid the "coffee ring" effect that plagues inkjet printers.

The outer edges of the ring that a coffee mug leaves behind are darker than the inside of the ring. That's because the solute is separated from the liquid during the evaporation process. That's what's called the coffee ring effect.

The way research in quantum technology will be taken forward has been laid out in a revised roadmap for the field.

Published today in the New Journal of Physics, leading European quantum researchers summarise the field's current status, and examine its challenges and goals.

In the roadmap:

Dr Rob Thew and Professor Nicolas Gisin look at quantum communication, and when we may expect to see long-distance quantum key distribution networks

A new study suggests that long-term exposure to secondhand smoke during childhood increases the risk of chronic obstructive pulmonary disease (COPD) death in adulthood. The study also suggests secondhand smoke exposure as an adult increases the risk of death not only from COPD but also several other conditions.

Years after the end of the Human Genome Project (HGP), which mapped the human genetic blueprint, its contributions to science and scientific culture are still unfolding.

UNIVERSITY PARK, Pa. -- The mechanics behind how an important process within the cell traps material before recycling it has puzzled scientists for years. But Penn State researchers have gained new insight into how this process seals off waste, much like a trash bag.
