Cataloging a year of blogging: complexity in evolution, general models, and philosophy

by Artem Kaznatcheev in Evolutionary Games Group

Last month, with just hours to spare in January, I shared a linkdex of the 14 cancer-related posts from TheEGG in 2016. Now, as February runs out, it’s time to reflect on the 15 non cancer-specific posts from last year. Although, as we’ll see, some of them are still related to mathematical oncology. With a […]...

Split Brain, Undivided Consciousness?

by Neuroskeptic in Neuroskeptic_Discover

A new paper challenges a decades-old theory in neuroscience: Split brain: divided perception but undivided consciousness



According to the famous work of Roger Sperry and Michael Gazzaniga, "split brain" patients seem to experience a split in consciousness: the left and the right side of their brain can independently become aware of, and respond, to stimuli. Split brain patients are those who underwent surgery to sever the corpus callosum, the nerve tract connecting the two hemispheres of ... Read more »

Distortions of Reality

by The Neurocritic in The Neurocritic





President Trump this week repeated an assertion he made shortly after his election: that millions of ballots cast illegally by undocumented immigrants cost him the popular vote. If true, this would suggest the wholesale corruption of American democracy.

Not to worry: As far as anyone knows, the president’s assertion is akin to saying that millions of unicorns also voted illegally.

- In a

Why we have not met Aliens yet?

by Usman Paracha in SayPeople

A huge of number of people keeps on thinking about the existence of some other intelligent beings in the universe but still we have not met any aliens. Why?

Earth is rare

Earth is special planet

One of the reasons that we have not met aliens is that Earth is rare and there is nothing just like Earth in the universe. In this regard, Paleontologist Peter Ward and astronomer Donald Brownlee presented the Rare Earth Hypothesis about 17 years ago.

According to the Rare Earth Hypothesis, t........ Read more »

Imagine: Listening to Songs Which Make Us More Generous

by Jalees Rehman in The Next Regeneration

It does not come as a surprise that background music in a café helps create the ambience and affects how much customers enjoy sipping their cappuccinos. But recent research suggests that the choice of lyrics can even impact the social behavior of customers. The researcher Nicolas Ruth and his colleagues from the University of Würzburg (Bavaria, Germany) assembled a playlist of 18 songs with pro-social lyrics which they had curated by surveying 74 participants in an online questionnaire as to w........

Is anybody out there? Talking to the Galactic Zookeepers

by gdw in FictionalFieldwork

The Zoo Hypothesis Hello? Anybody out there in the starry skies? If there are extra-terrestrial civilizations, why haven’t we heard from them yet? The sheer magnitude of the universe with its billions upon billions of stars has led many to suggest that life must have arisen more than once in the cosmos. Some have gone […]... Read more »

The blur doesn't cut it: AI can identify people in blurred images

by Dr. Jekyll in Lunatic Laboratories

A trio of researchers has found off-the-shelf AI software can be used to identify people in blurred or pixilated images. The researchers have uploaded a paper describing the experiments they carried out with AI software identification of people or other items in blurred out images, what they found and reveal just how accurate they found it could be.

Paralympic athletes and the rise of the cyborgs

by gdw in FictionalFieldwork

Para and super? The Olympics are over. They’ve brought us some good stories, some nice records, and (self-citation alert!) a humble blog post about the ethics of doping. But the Paralympics, their less mediatized cousin, are in full swing. Paralympians from all over the world gather to wow us with their athletic prowess in the Paralympic […]... Read more »

How Do Most People Do Mathematics?

by Stefan Buijsman. in United Academics

Mathematics is an important part of modern society. Science and engineering are hard to imagine without mathematics, and even simple things such as calculating the cost of groceries involve mathematics. So, it's not strange to stop and wonder what mathematics is. That turns out to be a very difficult question.... Read more »

Who made the Piltdown man? Inside one of science’s most (in)famous hoaxes

by gdw in FictionalFieldwork

There was always that nagging feeling of not being accepted, of whispers behind his back. They pretended to be open-minded, but in reality not belonging to the group of professionals was reason enough to dismiss his work and findings. In their eyes, he was just a solicitor. A hobbyist. He was tolerated, but their derision […]... Read more »

Do we need a doping Olympics? The ethics of doping in sports

There is only her and the track. The people standing on her left and right do not matter now. She has only one adversary: time. In her head she plays how the future might…will unfold. Forty seven strides. That’s all she needs. All things on the periphery disappear. Her world, her universe becomes a single […]... Read more »

Specialized neurons in emotional memory play important role in fear

by Dr. Jekyll in Lunatic Laboratories

Fear memory encoding, the process responsible for persistent reactions to trauma-associated cues, is influenced by a sparse but potent population of inhibitory cells called parvalbumin-interneurons (PV-INs) in the amygdala, according to a new study.

Another one bites the dust?

by Henkjan Honing in Music Matters

The music theory literature has been suggesting it for a long time: the idea that simultaneous sounding tones with frequency relationships that are low integer multiples, like 1:2 (octave) or 3:2 (a perfect fifth), are determinant of how listeners perceive consonance. It is an idea that is often related to the overtone structure of natural sounds (such as the voice or string instruments) suggesting that musical harmony is reflective or even a result of the acoustic structure that is found in nat........

Are animals (and AI’s) people too?

Charles gets up and balances on his short legs. During the brief ungainly walk to the dais, he fights the urge to scratch his arms. The vest that has been tailor-made for him itches. But it will help focus the committee on his purpose, focus on him as a person. He squats on the low […]... Read more »

The researchers examined Twitter users and the exchange of emails between Yahoo-Mail users in 90 countries with a minimum population of five million. In total, they analyzed........ Read more »

Mothers with diabetes more likely to have anti-fetal brain autoantibodies

by Dr. Jekyll in Lunatic Laboratories

Mothers of children with autism and were diagnosed with metabolic conditions during pregnancy, particularly gestational and type 2 diabetes, were more likely to have anti-fetal brain autoantibodies in their blood compared to healthy women of children with autism. The presence of these anti-fetal brain autoantibodies has been previously found to be specific to some mothers of children with autism and rare among mothers of children without autism.

Multiple realizability of replicator dynamics

by Artem Kaznatcheev in Evolutionary Games Group

Abstraction is my favorite part of mathematics. I find a certain beauty in seeing structures without their implementations, or structures that are preserved across various implementations. And although it seems possible to reason through analogy without (explicit) abstraction, I would not enjoy being restricted in such a way. In biology and medicine, however, I often […]...

Love, War and Genital Shape

by Miss Behavior in The Scorpion and the Frog

The size and shape of your junk may depend on how much sex your ancestors had… that is, at least, if you are a burying beetle. Buring beetles caught in the act. Photo by Jena Johnson. Burying beetles are unusual among insects in that they provide parental care and are often monogamous. When burying beetle pairs find a small dead bird or rodent, they pluck it bald, coat it in antibacterial and antifungal body secretions, and dig a hole around it. The female lays her eggs around the carcass-ba........ Read more »
