The effect that the introduction of environmental fiscal reform would have on an economic system has been the focus of study since the 1990s. However, studies of this type have until now failed to take the informal economy into consideration; this is an activity which in the case of Spain, for...

A team of researchers from Canada has developed a class of compounds which may help eradicate a neglected tropical disease that is currently hard to kill in its chronic form. The research was published ahead of print in Antimicrobial Agents and Chemotherapy. Fuente :...

El último número de la revista Nature muestra posibles vías en el desarrollo de nuevos fármacos para la artritis reumatoide, una patología sistémica autoinmune, crónica, que afecta principalmente a las articulaciones y cuya prevalencia en la población es cercana al 0,5%. En el estudio participa el...

Si bien México es considerado uno de los países líderes en producción de papaya, a menudo sus cosechas se ven afectadas por el virus de la mancha anular, el cual deja marcas en forma de anillo en la cáscara y ocasiona ablandamientos en algunas zonas, donde se concentran hongos que la echan a...

Diversos estudios han demostrado que la risa fortalece el sistema inmunológico, pues al hacerlo de manera frecuente liberamos gran cantidad de endorfinas que protegen al organismo de infecciones y lo vuelven más resistente a enfermedades crónico-degenerativas, como las cardiovasculares, diabetes, hipertensión e incluso...

La especie que históricamente era citada como la más abundante de las algas coralinas formadoras de mantos de rodolitos en el Golfo de California, México, es en realidad un complejo de cinco especies.

Scientists have obtained the first detailed molecular structure of a member of the Tet family of enzymes. The finding is important for the field of epigenetics because Tet enzymes chemically modify DNA, changing signposts that tell the cell's machinery "this gene is shut off" into other signs that say "ready for a change."...

Researchers from the Boston area, Mexico, and Norway have completed a comprehensive genomic analysis of cervical cancer in two patient populations. The study identified recurrent genetic mutations not previously found in cervical cancer, including at least one for which targeted treatments have been approved for other forms...

An international team of researchers in Mexico and the United States has uncovered a new genetic clue that contributes to an increased risk of developing type 2 diabetes, particularly the elevated risk among Mexican and other Latin American populations.

Wird Grünland intensiv genutzt, nimmt die Biodiversität ab. Besonders betroffen sind dabei seltene Arten, wie eine neue Studie unter der Leitung von Berner Pflanzenwissenschaftlern zeigt. Solche negativen Auswirkungen könnten reduziert werden, wenn Landwirte die Intensität ihrer Bewirtschaftung in...

If grassland is managed intensively, biodiversity typically declines. A new study led by Bernese plant ecologists shows that it is rare species that suffer the most. These negative effects could be reduced, if farmers varied the intensity of their land use between years. Fuente :...

El desarrollo inteligente es el que concilia un avance económico, inclusivo y sustentable, defiende el economista indio Nanak Kakwani, quien ha formulado una nueva metodología para medir la pobreza. Ahora hay un intento académico de medirlo en el bloque BRICS, empezando por Brasil. Los países emergentes, como los integrantes...

Radiotherapy (RT) after breast conserving surgery (BCS) has been shown to reduce the risk of breast cancer (BC) recurrence. However, although younger women tend to have more aggressive tumors and have higher risks of recurrence than older BC patients, they are less likely to receive RT after BCS,...

A recent study led by researchers from the Amyloidosis Center at Boston University School of Medicine and Boston Medical Center demonstrates that diflunisal, a generic anti-inflammatory drug, successfully reduced neurological decline and preserved the quality of life in patients with familial...
