The fishing port of Ondarroa, the Deba marina, the estuary at Gernika (beside the discharge stream of the waste water treatment plant) and the industrial ports of Pasaia and Santurtzi are the scenarios where the research was carried out between May and June 2012. The fish chosen for the study was the thicklip grey mullet (Chelonlabrosus).

Working with gut stem cells from humans and mice, scientists from the Johns Hopkins Children's Center and the University of Pittsburgh have successfully grown healthy intestine atop a 3-D scaffold made of a substance used in surgical sutures.

In a further step that takes their work well beyond proof of concept, researchers report their laboratory-created intestine successfully regenerated gut tissue in the colons of dogs with missing gut lining.

Burning a candle could be all it takes to make an inexpensive but powerful electric car battery, according to new research published in Electrochimica Acta. The research reveals that candle soot could be used to power the kind of lithium ion battery used in plug-in hybrid electric cars.

The authors of the study, from the Indian Institute of Technology in Hyderabad, India, say their discovery opens up the possibilities to use carbon in more powerful batteries, driving down the costs of portable power.

ONTARIO, OR - Sweetpotato, a warm-season root crop grown across the world, needs heat and humidity to flourish. In the United States, commercial sweetpotato production occurs predominantly in the southeastern states and California, while production farther north is limited. Recently, Oregon State University researchers discovered cultural practices that could help to increase sweetpotato production in the semiarid Pacific Northwest.

Oxford, October 6, 2015 - A blend of two polymers can be used to boost the efficiency of LEDs (light-emitting diodes), according to a research study published in the journal Applied Materials Today. Richard Friend of the Cavendish Laboratory, at the University of Cambridge and colleagues, have blended poly(9,9-dioctylfluorene) (F8) and a poly(para-phenylenevinylene) (PPV) copolymer known as Super Yellow (SY) and used cesium carbonate in their LED's negative electrode to minimize quenching and give them ultrahigh efficiency devices.

The color of dinosaurs is a fascinating topic, and in recent years the discovery of melanosomes - small, pigment-filled sacs - associated with fossilized dinosaur feathers has given rise to all sorts of speculation about our prehistoric pals, from the hue of their plumage to color's impact on behavior.

Lung cancer screening programs that utilize standardized reporting and include cardiothoracic surgeons as part of a multidisciplinary team can successfully be adopted into clinical practice without an increase in surgical intervention for non-cancerous disease, according to an article in the October 2015 issue of The Annals of Thoracic Surgery.

The tungsten lightbulb has served well over the century or so since it was introduced, but its days are numbered now with the arrival of LED lighting, which consume a tenth of the power of incandescent bulbs and have a lifespan 30 times longer. Potential uses of LEDs are not limited to illumination: smart lighting products are emerging that can offer various additional features, including linking your laptop or smartphone to the internet. Move over Wi-Fi, Li-Fi is here.

At a Chevron oil refinery in Hawaii, researchers are growing microalgae in a 5,000-liter photobioreactor, flowing wastewater from the refinery through the reactor, and taking advantage of the algae's appetite for chemical nutrients to polish the water, removing noxious chemicals, including 90% of the ammonia-nitrogen and 97% of the phosphorus.

The dust has now settled on the latest product launch from Apple, which for many trumped headlines about refugees, poverty and the battles for the Republican nomination and leadership of the UK Labour Party. We have new iPads, iPhones and more. But how new are they really?

Each year approximately 5-20% of U.S. residents get the flu and more than 200,000 people are hospitalized for flu-related complications. The cobas Influenza A/B test offers an effective, new diagnostic tool for the upcoming flu season and enables health care providers to provide faster diagnosis and treatment for patients in primary and urgent care settings, while the patient waits.

As Nevada and California endure a fourth year of unprecedented drought and this year’s Sierra Nevada snowpack is verified as a 500-year low, a group of Ph.D. scientists from Nevada are knocking on the front door of the tech-industry with a pitch for investment in next generation weather intelligence.

Extreme weather events such as the ongoing drought and mega-fires in the West, record-setting hurricanes in the East, and flash floods across the Mid-West cause upwards of $11 billion in damages each year in the United States.

Research published recently in Science as Culture suggests that men are surprisingly positive and open to the concept of having cancer-detecting biosensors implanted within their bodies – effectively making them cyborgs.

A first draft of the "tree of life" for the roughly 2.3 million named species of animals, plants, fungi and microbes -- from platypuses to puffballs -- has been released.

A collaborative effort among eleven institutions, the tree depicts the relationships among living things as they diverged from one another over time, tracing back to the beginning of life on Earth more than 3.5 billion years ago.
