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.

Los árboles que toleran la contaminación del suelo también son mejores para defenderse de plagas y patógenos. "Parece que el mismo acto de la tolerancia a la contaminación química puede dar una ventaja árboles sobre la invasión biológica", dice el Dr. Frederic E. Pitre de la Universidad de Montreal y uno de los investigadores responsables del descubrimiento.

While many electric vehicle owners will find it irritating and annoying to be hit with adverts when charging their vehicles, is this a sign of the times? The fact that many larger companies are willing and prepared to pay for advertising space on “free” charging devices seems to indicate that the marketing industry believes the sector is here to stay. So, will advertising be a help or a hindrance to the industry going forward?

Until the electric vehicle industry cracks the “mass market” it is vital that the cost of services and products is kept as low as possible. There will come a point when costs will have to rise, services will be chargeable and the whole dynamic will be very different than what we see today but, in the meantime, is advertising on “free” charging stations really a hindrance?

A Purdue University study shows that targeting plants with red and blue LEDs provides energy-efficient lighting in contained environments, a finding that could advance the development of crop-growth modules for space exploration.

There may be far fewer galaxies further out in the Universe then might be expected, suggests a new study based on simulations conducted using the Blue Waters supercomputer at the National Center for Supercomputing Applications, with resulting data transferred to SDSC Cloud at the San Diego Supercomputer Center at the University of California, San Diego, for future analysis. 

The study, published this week in the Astrophysical Journal Letters, shows the first results from the Renaissance Simulations, a suite of extremely high-resolution adaptive mesh refinement (AMR) calculations of high redshift galaxy formation. 

Moreover, these simulations show hundreds of well-resolved galaxies, allowing researchers to make several novel and verifiable predictions ahead of the October 2018 launch of the James Webb Space Telescope (JWST), a new space observatory that succeeds the Hubble Space Telescope.
