Neiker-Tecnalia (the Basque Institute for Agricultural Research and Development) is working on the development of new biotechnological tools to produce in vitro selected trees of the Pinus genus. Scientists at this technological centre have developed various techniques for propagation of Pinus radiata, Pinus pinea, Pinus pinaster and Pinus sylvestris by using tissue culture.

A little information can go a long way when it comes to understanding rodent-borne infectious disease, as shown by a new study led by scientist John Orrock of the University of Wisconsin-Madison and colleagues.
The researchers studied wild deer mouse populations on the Channel Islands off the southern coast of California. The mice carry a variant of hantavirus--a disease spread by rodents--called Sin Nombre virus.
Results of the study appear in the May issue of the journal American Naturalist.
A new study in the Journal of Consumer Research explains why consumers often indicate they are willing to pay more for a product that is not yet available—but are reluctant to pay that price when the product is ultimately launched.
University of Adelaide researchers have shown for the first time how peppermint helps to relieve Irritable Bowel Syndrome, which affects up to 20% of the population.
In a paper published this week in the international journal Pain, researchers from the University's Nerve-Gut Research Laboratory explain how peppermint activates an "anti-pain" channel in the colon, soothing inflammatory pain in the gastrointestinal tract.
COLUMBUS, Ohio – A new study shows how inflammation can help cause cancer. Chronic inflammation due to infection or to conditions such as chronic inflammatory bowel disease is associated with up to 25 percent of all cancers.
This study by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) found that inflammation stimulates a rise in levels of a molecule called microRNA-155 (miR-155).
Animals that reproduce asexually by somatic cloning have special mechanisms that delay ageing provide exceptionally good health. Scientists at the University of Gothenburg have shown how colony-forming ascidians (or sea squirts) can activate the enzyme telomerase, which protects DNA. This enzyme is more active also in humans who attain an advanced age.
Squamous cell cancers, which can occur in multiple organs in the body, can originate from hair follicle stem cells, a finding that could result in new strategies to treat and potentially prevent the disease, according to a study by researchers with UCLA's Jonsson Comprehensive Cancer Center and the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA.
DNA is under constant attack, from internal factors like free radicals and external ones like ionizing radiation. About 10 double-strand breaks – the kind that snap both backbones of the double helix – occur every time a human cell divides. To prevent not only gene mutations but broken chromosomes and chromosomal abnormalities known to cause cancer, infertility, and other diseases in humans, prompt, precise DNA repair is essential.
By identifying a surprising association of two intracellular proteins, University of Iowa researchers have laid the groundwork for the development of new therapies to treat B cell lymphomas and autoimmune disease.
A new study from the University of Gothenburg, Sweden, shows how analysing spinal fluid can help to detect Alzheimer's disease at an early stage. The researchers behind the study hope that their findings will contribute to a greater international breakthrough for this type of diagnostic method.
LOS ANGELES—(April 19, 2011)—Stepping outside to smoke a cigarette may not be enough to protect the lungs and life of a pregnant woman's unborn child, according to a new study in the American Journal of Physiology.
DALLAS – April 19, 2011 – Curbing carbohydrates is more effective than cutting calories for individuals who want to quickly reduce the amount of fat in their liver, report UT Southwestern Medical Center researchers.
"What this study tells us is that if your doctor says that you need to reduce the amount of fat in your liver, you can do something within a month," said Dr. Jeffrey Browning, assistant professor of internal medicine at UT Southwestern and the study's lead author.
A potential vaccine against bacteria that cause serious gastric disorders including stomach cancer may be a step closer following a pioneering study by a University of Guelph chemist.
In the first published study of its kind, a team led by Prof. Mario Monteiro, Department of Chemistry, found a carbohydrate-based antigen caused mice to develop antibodies against a common bacterium linked to gastric cancer.
"This is the first jab at a sugar-based vaccine against Helicobacter pylori," said Monteiro, who completed the study with former undergrad student Stacey Britton.
The future mood swings of people with bipolar disorder can be predicted by their current thoughts and behaviour, a study published today (Tuesday) has found.
Psychologists from the Universities of Manchester and Lancaster say their findings are important because they mean talking therapies, like cognitive behavioural therapy (CBT), could prove effective treatments for the condition.
BOSTON – With ubiquitous social media sites like Facebook and Twitter blurring private and professional lines, there is an increasing need for physicians to create a healthy distance between their work and home online identities, two Beth Israel Deaconess Medical Center physicians assert.
