To protect consumers from foodborne illness, produce farmers should wait 24 hours after a rain or irrigating their fields to harvest crops, according to new research published in the journal Applied and Environmental Microbiology.

Rain or irrigation creates soil conditions that are more hospitable to Listeria monocytogenes, which when ingested may cause the human illness Listeriosis. Waiting to harvest crops reduces the risk of exposure to the pathogen, which could land on fresh produce.

Rutgers marine researchers and New Jersey fishermen are piecing together the details of the strange, gender-bending sex lives of black sea bass – a study that could improve understanding of the bass population and help the beleaguered recreational fishing industry.

Scientists have long known black sea bass are “protogynous hermaphrodites,” a species in which fish that begin life as females can switch gender to male. But the details of how and why that happens are not completely understood.

Now, there’s thinking the change is triggered when the number of males in a local population declines.  Not enough guys? Some black sea bass ladies make the switch.

As Greece prepares for its referendum, Takis Grigoriou takes Greece to task for its highly polluting lignite power sector, its ditching of a successful solar program in favour of more coal, the minimal insulation in its buildings that locks in high fuel bills, and Syriza's failure to tackle these issues. The good news? Greece's latest €1.4bn coal project looks like going unfunded.

Instead of phasing out lignite Greece opted to engage in a long battle to preserve the ailing industry while putting an abrupt end to solar energy development by blocking new applications.

Wearable devices that monitor physical well-being and fitness are incredibly popular. The number sold is expected to increase from 17.7 million in 2014 to more than 40 million this year.1

Personally, I use the Jawbone UP24 and have found it very useful for keeping track of my daily steps and sleep patterns. Most of these devices come set with a default goal of 10,000 steps a day, which is a number commonly associated with a basic or moderate level of fitness.

Un experimento diseñado originalmente para probar las habilidades visuales de los pulpos y las sepias, ha dado a los investigadores de la Universidad de Bristol una visión sin precedentes de la capacidad humana para percibir la luz polarizada, un súper sentido que la mayoría de nosotros ni siquiera sabemos que tenemos.

Todos estamos familiarizados con el color y el brillo, pero hay una tercera propiedad de la luz, la "polarización", que nos dice la orientación en la que las ondas de luz están oscilando.

Un profesor de la Universidad de Wyoming ha hecho un descubrimiento que responde a una pregunta de casi 100 años de antigüedad sobre el movimiento subterráneo del agua, con implicaciones para la agricultura, la hidrología, la ciencia climatológica y otros campos.

Después de décadas de esfuerzo, Fred Ogden, Director en Jefe de Ingeniería, Medio Ambiente y Recursos Naturales del Departamento de Ingeniería Civil y Arquitectura de la Escuela Haub de Medio Ambiente y Recursos Naturales de la Universidad de Wyoming, y un equipo de colaboradores, publicaron sus hallazgos en la revista Water Resources Research esta primavera.
