The world may not be well prepared for the next significant tsunami, reports Northwestern University tsunami expert Emile A. Okal in a new study that includes a “wisdom index” for 17 tsunamis since 2004.

Los científicos tienen pruebas de que Popeye tenía razón: Las espinacas te hacen más fuerte. Pero es el alto contenido de nitratos en las verduras de hoja verde, no el hierro, lo que crea el efecto.

Sobre la base de un creciente cuerpo de trabajo que sugiere que la dieta rica en nitratos mejora el rendimiento muscular en muchos atletas de élite, los investigadores de la Escuela de Medicina de la Universidad de St. Louis en Washington, encontraron que el consumo de jugo de remolacha concentrado, también de alto contenido en nitratos, aumenta la fuerza muscular en pacientes con insuficiencia cardíaca.

New research has found rising sea levels and stronger storms associated with climate change will produce longer-lasting, more intense periods of flooding.

If you are struggling with weight gain, you might be surprised to know that your parents had it easier - they could eat more and exercise less, and still avoid obesity, according to a recent study out of York University's Faculty of Health.

"Our study results suggest that if you are 25, you'd have to eat even less and exercise more than those older, to prevent gaining weight," says Professor Jennifer Kuk in the School of Kinesiology and Health Science. "However, it also indicates there may be other specific changes contributing to the rise in obesity beyond just diet and exercise."

Food waste in the U.S. is a big problem, accounting for about 31 percent of the nation’s food supply, or 133 billion pounds.

Methane is a greenhouse gas with a warming potential 21 times that of carbon dioxide — and landfills are the third largest source of methane emissions in the U.S.
