Helicobacter pylori and stem cells in the gastric crypt

by Artem Kaznatcheev in Evolutionary Games Group

Last Friday, the 4th Integrated Mathematical Oncology Workshop finished here at Moffitt. The event drew a variety of internal and external participants — you can see a blurry photo of many of them above — and was structured as a competition between four teams specializing in four different domains: Microbiome, Hepatitis C, Human papillomavirus, and […]...

Evolutionary Sins: The Gender Gap In Spatial Cognition And Navigation

by Alexis Delanoir in How to Paint Your Panda

Recent research based on the Twe and Tjimba people of northwestern Namibia is suggested to lend evidence that gender gaps in spatial cognition are a result of evolutionary pressures, as men with higher spatial cognition are more successful in these tribes at mating and producing offspring. This post examines the literature and comes to a different conclusion, warning against hasty evolutionary explanations for behavioural traits.... Read more »

Bernstein polynomials and non-linear public goods in tumours

by Artem Kaznatcheev in Evolutionary Games Group

By analogy, or maybe homage, to standard game theory, when we discuss the payoffs of an evolutionary game, we usually tell the story of two prototype agents representing their respective strategies meeting at random and interacting. For my stories of yarn, knitting needles, and clandestine meetings in the dark of night, I even give these […]... Read more »

Stem cells, branching processes and stochasticity in cancer

by Artem Kaznatcheev in Evolutionary Games Group

When you were born, you probably had 270 bones in your body. Unless you’ve experienced some very drastic traumas, and assuming that you are fully grown, then you probably have 206 bones now. Much like the number and types of internal organs, we can call this question of science solved. Unfortunately, it isn’t always helpful […]... Read more »

Merit’s Liquidity

Are Black Holes just in Our Imagination?!

by Gabriel in Lunatic Laboratories

Black holes, physicists have been fighting over them forever, heck there is even a book entitled the black hole war! (which I do recommend for anyone interested) It’s no real surprise since they are the ultimate unknown – the blackest and most dense objects in the universe that do not even let light escape. And as if they weren't bizarre enough to begin with, now add this to the mix: they don’t exist.... Read more »

Walking Really Is Just Falling and Catching Yourself

by Elizabeth Preston in Inkfish

The flailing of a gymnast who’s missed a step on the balance beam might not be far off from what the rest of us experience every day. Each step we take is really a tiny fall, a mathematical model suggests. The random-looking variation in our footfalls is actually a series of corrections. Our strides are […]The post Walking Really Is Just Falling and Catching Yourself appeared first on Inkfish.... Read more »

I have spent this week in Castiglioncello participating to the Conference DICE 2014. This Conference is organized with a cadence of two years with the main efforts due to Thomas Elze. I have been a participant to the 2006 edition where I gave a talk about decoherence and thermodynamic limit (see here and here). This […]... Read more »

Transcendental idealism and Post’s variant of the Church-Turing thesis

by Artem Kaznatcheev in Evolutionary Games Group

One of the exciting things in reading philosophy, its history in particular, is experiencing the tension between different schools of thought. This excitement turns to beauty if a clear synthesis emerges to reconcile the conflicting ideas. In the middle to late 18th century, as the Age of Enlightenment was giving way to the Romantic era, […]... Read more »

Fingertips can actually perform calculations

by Usman Paracha in SayPeople

Main Point:

Nerve endings on our fingertips have the same ability of performing complex neural computations as we can find in our brain.

Published in:

Nature Nanotechnology

Study Further:

Researchers have found that our fingertips are able to differentiate the edges and this process of getting knowledge of orientation of edges is performed by both touch and visual senses. Most of these senses and computations occur in the brain as it contains cells of both touch and see that are s........ Read more »

Pigeon Gamblers Treat Risk Just Like Humans Do

by Elizabeth Preston in Inkfish

If you watch poker coverage on television, you probably won’t hear the commentators compare players to pigeons. Maybe they should. The birds don’t play a great game of hold ‘em, but the way they think about risk might be strikingly similar to the way we do. Researchers discovered this by putting humans and birds through […]The post Pigeon Gamblers Treat Risk Just Like Humans Do appeared first on Inkfish.... Read more »

Falsifiability and Gandy’s variant of the Church-Turing thesis

by Artem Kaznatcheev in Evolutionary Games Group

In 1936, two years after Karl Popper published the first German version of The Logic of Scientific Discovery and introduced falsifiability; Alonzo Church, Alan Turing, and Emil Post each published independent papers on the Entscheidungsproblem and introducing the lambda calculus, Turing machines, and Post-Turing machines as mathematical models of computation. The years after saw many […]... Read more »

Whitman Was Not a Neuroscientist

by The Neurocritic in The Neurocritic

Do I contradict myself?Very well then I contradict myself,(I am large, I contain multitudes.)-Walt Whitman, "Song of Myself" (from Leaves of Grass)Science is the search for objective truth based on physical laws of the universe. Scientific theories try to explain the consistent and predictable behavior of natural systems. They are generally reductionist, meaning that complex systems are reduced to simpler and more fundamental elements. The principles of physics, for instance, are expressed in th........ Read more »

The Holographic Universe [we might Live in!]

by Gabriel in Lunatic Laboratories

Are you feeling a little… flat? Well that might be because you are only in 2 dimensions. I know what you’re thinking, insane! Well first check the name of the business and second, check out the science. In fact, it may seem like a joke, but the math suggests that it could very well be true and with it could come a deeper understanding of the universe. Testing this hypothesis (which was first made in the late 90’s) has been harder to do than you might think, but that has now changed. We are........ Read more »

Brian Hooker's Hooked Hoax: Measles-Mumps-Rubella (MMR) Vaccination and Autism Spectrum Disorder

by Alexis Delanoir in How to Paint Your Panda

10 years after the initial study by DeStefano et al. (2004) was conducted, famous anti-vaccine alarmist Brian Hooker, along with Andrew Wakefield, are talking about a "whistleblower" in the CDC claiming that the original data was fraudulent, and was masking a 336% increased risk in ASD in African American boys receiving the MMR vaccine "on time." Did Hooker prove anything in his new study, however? Only that he doesn't understand epidemiology or statistics.... Read more »

Competition for ecological niches limits evolution of new species | @GrrlScientist

A recently published study finds that competition for ecological niches limits the evolution of new species. Further, this study finds that speciation rate slows or even stops as available ecological niches fill up. Continue reading...... Read more »
