The brain works as a ‘cyclops,’ compensating the optical differences between the eyes

The eyes differ in their optical properties what results in a blur projected in each retina, despite we see sharp images because the visual system calibrates itself. An international research performed by the Consejo Superior de Investigaciones Científicas has discovered that when each eye separately has a different level of blur, our brain uses as sharp reference the image projected through the less aberrated eye. The research has been published in Current Biology. —> Read More Here

McDonald’s Is Removing Human Antibiotics From Its Chicken. Here’s Why That’s Good News For All Of Us

McDonald’s announced on Wednesday that within the next two years, U.S. restaurants will stop serving chicken raised with antibiotics that are used to fight human infections. Even if you’re not a McDonald’s customer, that’s good news.

“For public health, this is really a game changer,” Gail Hansen, a senior officer for Pew Charitable Trusts’ antibiotic resistance project, told Reuters, and a move that could potentially influence other major players in the food industry.

Antibiotics in food animals are one contributing factor to the growing number of antibiotic-resistant “superbugs”, which are estimated to infect and kill up to 10 million people worldwide by 2050 if more serious action isn’t taken to stop them.

These “superbugs” are a class of mutated microbes, generally bacteria, that has evolved as they multiply to outsmart the very drugs we use to fight the infections they cause. Experts say that overuse of antibiotics is a major factor in the proliferation of such drug-resistant bacteria.

Antibiotics are often given to the animals we eat to help them gain weight quickly — a measure to increase the volume of a farm’s output and, by extension, its revenue. But the evidence against this —> Read More Here
