El petróleo. En el Siglo 20, acceso a esta fuente de energía económica y abundante trajo una de las eras de mayor progreso en la historia humana.

Aceleradamente, esta “Era del Petróleo Barato” se acerca a su fin. Para este año, la Administración de Información de Energía (EIA) de los Estados Unidos estableció que se consumirá 19.52 millones de barriles de petróleo y sus derivados al día en América del Norte a partir de un suministro de producción de solo 16.32 millones de barriles.

Aunque su obra fue subestimada, Ana Roqué de Duprey legó uno de los textos más relevantes en la historia de la ciencia de principios del siglo XX en las Américas. Hoy, 90 años después de escribir la ‘Botánica antillana’, una investigación revela el valor del libro inédito.

Así comienza la crónica que el periodista, Eliván Martínez Mercado escribió como producto de su trabajo para el Centro de Periodismo Investigativo. Quedé fascinada desde la primera vez que Eliván compartió esta historia conmigo y cuando ustedes lean esta excelente pieza periodística, seguro sabrán el porqué.

Stem cell therapies offer the potential to treat diseases or conditions for which few treatments exist.

Stem cells, sometimes called the body’s “master cells,” are the precursor cells that develop into blood, brain, bones and all of your organs. Their promise in medical treatments is that they have the potential to repair, restore, replace and regenerate cells that could then be used to treat many medical conditions and diseases.
