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

Feds Set Food Waste Reduction Goals
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. It makes up 21 percent of U.S. municipal solid waste in landfills, and as a result it accounts for the lion’s share of landfill methane emissions. 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.
Nuevo estudio encuentra erupciones masivas probablemente desencadenaron una extinción masiva
Hace unos 252 millones años, la vida en la Tierra se derrumbó en una forma espectacular y sin precedentes, ya que más del 96 por ciento de las especies marinas y el 70 por ciento de las especies terrestres desaparecieron en un instante geológico. La llamada extinción de finales del Pérmico o más comúnmente, la "Gran Mortandad", sigue siendo el evento de extinción más grave en la historia de la Tierra.
El jugo de la remolacha aumenta el rendimiento muscular rápidamente
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.
Selectively logged Amazon forests play important role in climate
With careful management, selectively logged tropical Amazonian forests can recover their carbon stocks within a cutting cycle of 20 to 30 years, according to researchers who report their findings in the Cell Press journal Current Biology on September 21. The findings show that sustainably logged tropical forests continue to play a key role in global carbon sequestration, with important implications for global climate.
Why do Millenials, Gen Y have more trouble keeping excess weight off?
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."
