VIDEO: New Breed of Robots Can Adapt to Injury

By Carl Engelking | May 28, 2015 4:14 pm

A new breed of robots have proven that losing a limb or two really is “just a flesh wound.”

Roboticists Antoine Cully and Jean-Baptiste Moret have built an algorithm that allows robots to detect damage — like losing a leg — and alter their walking motion in order to remain operational. Like an animal that injured its paw, these robots teach themselves to walk with a limp when the going gets tough.
Learning to Limp
For a six-legged robot, if just one leg malfunctions, it’s game …

Reduce Your Prejudices While You Sleep

By Xiaoqing Hu, University of Texas at Austin | May 28, 2015 1:33 pm

Your brain does a lot when you are asleep. It’s when you consolidate memories, and integrate the things you’ve learned during the day into your existing knowledge structure. We now have lots of evidence that while you are sleeping, specific memories can be reactivated and thus strengthened.

We wondered whether sleep could play a role in undoing implicit social biases. These are the learned negative associations we make through repeat exposure – things like stereotypes about women no …

Butterflies Have an Extra Stomach Attached to Their Vaginas

By Elizabeth Preston | May 28, 2015 10:31 am

One thing you won’t find in the story of the Very Hungry Caterpillar is the part where after transforming into a butterfly, he mates with a female who has a Very Hungry Reproductive Tract waiting to devour his sperm. She has a special digestive organ just for this purpose. It’s so powerful that it could even compete with the gut that let the caterpillar, in his more innocent days, chew through those five oranges.

This sperm-hungry organ is called the bursa copulatrix. In female butterfl …

Farms of the Future Will Use Drones, Robots and GPS

By Alex Thomasson, Texas A&M University | May 27, 2015 5:18 pm

Today’s agriculture has transformed into a high-tech enterprise that most 20th-century farmers might barely recognize.

After all, it was only around 100 years ago that farming in the US transitioned from animal power to combustion engines. Over the past 20 years the global positioning system (GPS), electronic sensors and other new tools have moved farming even further into a technological wonderland.

Beyond the now de rigeur air conditioning and stereo system, a modern large tractor …

One Chameleon, Eleven Chameleons: Genetics Reveal Cryptic Species in Madagascar's Panther Chameleon

By Christie Wilcox | May 27, 2015 4:03 pm

Perhaps the most common way that we tell different species apart is by looks. Different colors often mean deep-rooted differences, but in some species, color is a fluid concept. Take the chameleons: though it’s a myth that they can match any color they see around them, they are able to modify the patterns on their bodies to blend in, and some are known for dizzying color changes that are used as social signals — a colorful way of communicating with the chameleons around them.

The panth …

What To Do About A Slow Peer Reviewer?

By Neuroskeptic | May 27, 2015 6:58 am

An amusing editorial in the neuroscience journal Cortex discusses the excuses scientists use to explain why they didn’t submit their peer reviews on time:
Following our nagging for late reviews, we learned that one reviewer had to take their cat to the vet, another was busy buying Christmas presents, one was planning their holidays, an unfortunate one had their office broken into […] others agreed to review whereas indeed they really intended to withdraw, or were just too busy to reply.

Seriously, Science?

She had an extra nipple where?!?

By Seriously Science | May 27, 2015 6:00 am

Yup, you guessed it–according to this case study, a woman was found to have an extra nipple… in her vulva! And guess what else? It produced milk! Although extra nipples aren’t all that common, they usually can be found along the “milk line” (the imaginary line on a person’s torso that correlates with the line between multiple pairs of nipples on other mammals). But extra nipples have also been reported on other places, like the foot. So this extra nipple is unusual for its location. But  …


The Eye Parasite That Can Get In Through Your Contact Lens

By Hany Elsheikha, University of Nottingham | May 26, 2015 1:29 pm

A recent eye infection suffered by 18-year-old Nottingham University student Jess Greaney is the kind of story that fills us with horror. Greaney had keratitis, an inflammation of the cornea, caused by Acanthamoeba castellanii, a parasite that was living and feasting on her eye.

A. castellanii is a ubiquitous organism, found in many ecosystems worldwide. It is able to survive in harsh environmental circumstances – even in some contact lens solutions – and this is not the first occurre …

The Cyborg Action Heroine of 'Mad Max'

By Jeremy Hsu | May 26, 2015 11:59 am

Many science fiction films showcase cyborg technologies that give ordinary humans superhuman powers. The film “Mad Max: Fury Road” takes a very different route by featuring a heroine with an artificial left arm and no superhuman powers. That doesn’t stop the character named Imperator Furiosa, played by actress Charlize Theron, from proving herself a capable warrior in the post-apocalyptic future. She drives a behemoth “war rig” vehicle. She shoots a variety of long guns and handguns. She wr …
