Costs of natural hazards are at historically high levels, and show an increasing trend. Cost assessments of natural hazards often only cover direct costs and even these are assumed to be at least 50% higher than international assessments report. However, besides direct damage, also indirect damage...

When and where did the ancient Iapetus Ocean suture (the most fundamental Appalachian structure) form? Is part of New England made up of ancient African-derived rocks? What is the Moretown terrane? A new study finds new evidence for an earlier closing of the Iapetus that is farther west than...

An ancient form of meditation and exercise could help women who suffer from urinary incontinence, according to a new study. researchers discovered that a yoga training program, designed to improve pelvic health, can help women gain more control over their urination and avoid accidental urine...

Die Abschätzung der Kosten von Naturkatastrophen decken allerdings häufig nur die direkten Kosten ab, und selbst von diesen wird vermutet, dass sie mindestens 50% höher sind, als internationale Schätzungen angeben. Neben den direkten Schäden sind aber auch indirekte Schäden relevant. Fuente :...

Manuel Arruebo, de la Universidad de Zaragoza, se ha puesto manos a la obra para desarrollar una nueva tecnología de nanopartículas inyectables y biodegradables que se activarán con un puntero láser y suministrarán a demanda fármacos anestésicos contra el dolor ciático y de articulaciones....

Mientras la atención del Kremlin se dirige a Ucrania, el Emirato del Cáucaso, un grupo armado que busca crear un estado islámico en el norte del Cáucaso, amenaza la seguridad interna de Rusia de nuevas maneras. La muerte del veterano líder del Emirato, Doku Umarov, desató el pasado otoño boreal una lucha interna de poder...

Tras una semana en la que se sucedieron una masacre dentro de un campamento de la ONU y una matanza étnica en una zona petrolera, la comunidad internacional se pregunta si queda alguna posibilidad de salvar vidas en Sudán del Sur. A puertas cerradas, el Consejo de Seguridad de la ONU observó un...

Una coalición de 134 inversores institucionales reclamó a empresas trasnacionales que adopten políticas de transparencia en sus cadenas de suministro y que refuercen la asistencia a sobrevivientes y familiares que aún sufren las consecuencias del incendio que hace un año derrumbó un centro textil...

Biologists have discovered how an outer shield over T-type channels change the electrochemical signaling of heart and brain cells. Understanding how these shields work will help researchers eventually develop a new class of drugs for treating epilepsy, cardiovascular disease and cancer. The...

The discovery of an unknown cellular pathway has helped scientists and physicians better understand end-stage liver disease and offers a potential target for new therapeutics that could slow or even reverse the disease's progression. Although cirrhosis of the liver is most commonly associated with...

A 'brown dwarf' star that appears to be the coldest of its kind -- as frosty as Earth's North Pole -- has been discovered by astronomers. The object's distance at 7.2 light-years away, making it the fourth closest system to our Sun. Fuente : http://feeds.sciencedaily.com/~r/sciencedaily/~3/i...

A next-generation genome editing system substantially decreases the risk of producing unwanted, off-target gene mutations. Researchers report a new CRISPR-based RNA-guided nuclease technology that uses two guide RNAs, significantly reducing the chance of cutting through DNA strands at mismatched...

A novel DNA vaccine is being trialed to kill cancer, not by attacking tumor cells, but targeting the blood vessels that keep them alive. The vaccine also indirectly creates an immune response to the tumor itself, amplifying the attack by a phenomenon called epitope spreading. The team injected mice...

Científicos de la Universidad Autónoma de Zacatecas (UAZ), en colaboración con expertos del Centro de Investigación y Desarrollo en Criotecnología de Alimentos, en Buenos Aires, Argentina, buscan hacer uso de colonias de bacterias conocidas comoLactobacillus bulgaricus (conocidas popularmente como...

Inflammation has long been considered an integral part of the biological process that leads to deadly scarring in idiopathic pulmonary fibrosis. New research, however, suggests that a little inflammation may also be crucial to the healing and repair processes in the lungs. "The role of inflammation...

Large sections of the genome that were once referred to as 'junk' DNA have been linked to human heart failure, according to research. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn't code for proteins. But emerging research in recent years has...

By studying the reproductive cells of nematodes -- tiny worms found in soil and compost bins -- a researcher identified the Piwi/piRNA genome silencing pathway, the loss of which results in infertility after many generations. This study also found a signaling pathway -- a series of molecular...

El arroz, alimento ancestral y básico de Corea del Sur, experimenta una crisis en la que se mezclan hábitos alimentarios de la modernidad y temores fundados de los agricultores. Para cumplir compromisos ante la Organización Mundial del Comercio (OMC), el gobierno deberá decidir en junio qué hace...

Almost half of all homeless men who took part in a study had suffered at least one traumatic brain injury in their life and 87 percent of those injuries occurred before the men lost their homes. While assaults were a major cause of those traumatic brain injuries, or TBIs, (60 per cent) many were...

La última vez que vino a España le retuvieron su sospechoso equipaje en Barajas, pero esta vez ha pasado con sus seis maletas llenas de cachivaches. El mátemático Jin Akiyama, toda una estrella de la televisión en Japón, ha presentado esta semana sus números más sorprendentes en la Residencia de...

The emerging field of synthetic biology crosses the boundary between science and design, in order to design and manufacture biologically based parts, devices and systems that do not exist in the natural world, as well as the redesign of existing, natural biological systems. This new technology has...

I dagsläget är det ofta kostnaderna som styr vilka beslut som tas i företag som utvecklar mjukvaruintensiva produkter. Blekinge Tekniska Högskola, BTH, har nyligen beviljats pengar från KK-stiftelsen i Sverige för att hjälpa dessa företag att ytterligare förbättra ett mer framgångsrikt och...
