El Niño years can have a big impact on the littlest plants in the ocean, and NASA scientists are studying the relationship between the two. In El Niño years, huge masses of warm water – equivalent to about half of the volume of the Mediterranean Sea – slosh east across the Pacific Ocean towards South America. While this warm water changes storm systems in the atmosphere, it also has an impact below the ocean’s surface. These impacts, which researchers can visualize with satellite data, can ripple up the food chain to fisheries and the livelihoods of fishermen.

La formación de un cambio en el patrón de las temperaturas superficiales del mar en el medio del Océano Pacífico Norte puede predecir un mayor riesgo de olas de calor del verano en la mitad oriental de los EE. UU, con hasta 50 días de anticipación.

El patrón contrasta el agua más cálida que el promedio con el agua procedente de mares más fríos de lo normal. Cuando aparece, las probabilidades de que el calor extremo se deje sentir durante... 

Después de casi 50 años de servicio, la última central térmica de carbón de Escocia, la central eléctrica de Longannet, finalmente ha sido cerrada, poniendo fin a más de 100 años de la quema de carbón para generar electricidad.

Es un momento importante para Scottish Power, que mira hacia adelante para limpiar las... 

After nearly 50 years of service, Scotland’s last coal-fired power plant — Longannet Power Station — has finally gone offline, putting an end to over 100 years of burning coal for electricity.

It’s an important moment for Scottish Power, which looks ahead to clean power initiatives with the goal of going all-renewable by 2020,

But it’s also a very symbolic action for the world. Hopefully other nations will follow suit, creating a domino effect as country by country eliminates its coal plants — like the one above — in favor of renewable alternatives.

Initial findings from the Walnuts and Healthy Aging (WAHA) study presented at Experimental Biology 2016 (EB) indicate that daily walnut consumption positively impacts blood cholesterol levels without adverse effects on body weight among older adults. The WAHA study is a dual site two-year clinical trial conducted by researchers from the Hospital Clinic of Barcelona and Loma Linda University and is aimed at determining the effect of walnuts on age-related health issues. 

"Given walnuts are a high-energy food, a prevailing concern has been that their long term consumption might be associated with weight gain," said Dr. Emilio Ros, director of the Lipid Clinic, Endocrinology & Nutrition Service at the Hospital Clinic of Barcelona. "The preliminary results of the WAHA study demonstrate that daily consumption of walnuts for one year by a sizable cohort of aging free-living persons has no adverse effects on body weight. They also show that the well-known cholesterol-lowering effect of walnut diets works equally well in the elderly and is maintained in the long term. Acquiring the good fats and other nutrients from walnuts while keeping adiposity at bay and reducing blood cholesterol levels are important to overall nutritional well-being of aging adults. It's encouraging to see that eating walnuts may benefit this particular population."
