When lexical competition becomes lexical cooperation

by Dan Mirman in Minding the Brain

Lexical neighborhood effects are one of the most robust findings in spoken word recognition: words with many similar-sounding words ("neighbors") are recognized more slowly and less accurately than words with few neighbors. About 10 years ago, when I was just starting my post-doc training with Jim Magnuson, we wondered about semantic neighborhood effects. We found that things were less straightforward in semantics: near semantic neighbors slowed down visual word recognition, but distant semantic........ Read more »

Star Trek Phasers, Coming To Us Sooner or Laser

by Mark E. Lasbury in The 'Scope

Can we make a Star Trek phaser? In a classic example of life imitating art, the militaries of many countries are actively pursuing such directed energy weapons. So far, we’ve developed high-energy lasers and masers, particle beams, and something that looks a lot like an aimed lightning bolt. But our versions are huge, what must be overcome to make hand-held versions?... Read more »

Protecting crops by blocking insect genes: the case for RNA interference

by Betty Zou in Eat, Read, Science

A promising area of transgenic plant research is focused on the use of RNA interference, or RNAi, to control insect pests. For any gene to be expressed, the DNA must first be read and converted into RNA. The RNA message is then decoded to produce a protein. Think of your cell as a house and the DNA as the master building plan for that house. Every time you need to make a repair, the general contractor consults the building plan and sends a message to the tradesperson to make the component that i........ Read more »

What gives wine its taste? (We heard it’s on the grapevine…)

Schizophrenia and the risk of fractures

by Paul Whiteley in Questioning Answers

The systematic review and meta-analysis published by Brendon Stubbs and colleagues [1] provides some food for thought for healthcare providers and others looking at the wider implications following a diagnosis of schizophrenia. "People with schizophrenia are at significantly increased risk of fractures" was the conclusion reached based on the collected analysis of tens of thousands of people diagnosed with schizophrenia compared with nearly 4 million controls.My immediate thought (and tweet) whe........

Short history of iterated prisoner’s dilemma tournaments

by Artem Kaznatcheev in Evolutionary Games Group

Nineteen Eighty — if I had to pick the year that computational modeling invaded evolutionary game theory then that would be it. In March, 1980 — exactly thirty-five years ago — was when Robert Axelrod, a professor of political science at University of Michigan, published the results of his first tournament for iterated prisoner’s dilemma […]...

Drug already on the market could help treat MS and other neurological diseases

by Dr. Jekyll in Lunatic Laboratories

Multiple sclerosis, unless you suffer from nerve damage it is a pain you (thankfully) will never have to feel. In most cases, treating the brutal pain caused by this (and other neurological diseases) is the only help that can be offered to people. The pain is caused by damage to myelin, the fatty insulator that enables communication between nerve cells, which characterizes multiple sclerosis (MS) and other devastating neurological diseases....

You are what you eat

by naturallyspeakingpodcast in Naturally Speaking Podcast

Ecologists have long tried to understand what animals get up to when they’re not being observed. GPS technologies have enabled unprecedented remote-tracking, but some behaviours – such as diet – are a little more tricky to track. In this post James Grecian (@JamesGrecian), a marine ecologist at the Institute, discusses a technique he uses to track the diet of marine seabirds across some of the world’s […]

Extinction Edge: a new thriller on how epigenetic changes induced by viruses could kill us all

by EE Giorgi in CHIMERAS

Today my friend Nicholas Sansbury Smith releases Extinction Edge, the sequel to Extinction Horizon, a sci-fi thriller where humanity is driven to extinction by a lethal virus. I posted an interview with Nick for the release of his first book, but today I wanted to talk about the science behind his premise: can a virus induce epigenetic changes?In a way, Nick's premise is similar to the premise I used in Chimeras: a large part of our DNA is made of pseudogenes, which are ancient genes that are no........

 The gift of feeling powerful: “I find myself so inspiring”

by Doug Keene in The Jury Room

We have written about power poses and other strategies to help yourself feel powerful.  Be clear, though—you do not become more powerful by doing such things, but it might make you feel that way, which in itself can be communicated as confidence or authority. This post isn’t about how to make yourself feel powerful, it […]

Systemic low grade inflammation and bowel issues in autism?

The paper from Katarina Babinská and colleagues [1] (open-access here) presents an interesting, if preliminary take on two potentially important issues linked to at least some cases of autism: gastrointestinal (GI) issues and inflammation (see here and see here respectively).Detailing the examination of plasma levels of a compound called high mobility group box 1 protein (HMGB1), a protein which has the apparent ability to 'bend DNA' and has some pretty potent immune effects [2] (one paper........

Single-Unit Recordings Reveal Limitations of fMRI MVPA?

by Neuroskeptic in Neuroskeptic_Discover

Multi-voxel pattern analysis (MVPA) is an increasingly popular approach for analyzing the results of fMRI scanning experiments that measure brain activity. MVPA searches for patterns of activation that correlate with a particular mental state. This is called 'decoding' neural activity.

Now a new paper in the Journal of Neuroscience from Caltech neuroscientists Julien Dubois et al. reports that MVPA is unable to decode certain kinds of information, even though single-unit recordings confirm th... Read more »

A Theory of Robust Supply Chains

by Andreas Wieland in Supply Chain Management Research

Strategies and practices to achieve supply chain resilience have been at the heart of supply chain management practice and research for almost a decade. However, such efforts have often focused on ways to make supply chains more reactive to turbulence and disruptions. In our recent article, Antecedents and Dimensions of Supply Chain Robustness, my co-authors, Christian […]... Read more »

Chancelloriids Revised

by Marc in Teaching Biology

Many Cambrian fossils are simply spines and sclerites unassociated with any body. Few of the exceptionally-preserved Cambrian freaks come with spines attached, and some of the most prominent of these are the chancelloriids. Originally described as sponges by Charles Doolittle Walcott back in 1920 (Walcott, 1920), modern researchers have found that the spines are very similar to those […]

Science shows intermittent fasting diet could extend life

by Dr. Jekyll in Lunatic Laboratories

Think of it as interval training for the dinner table. Proponents of fasting style diets will be first to tell you there are health benefits, heck we've even covered some of the science here at the labs. Well new research shows that putting people on a intermittent fasting (or IF) diet may mimic some of the benefits of actual fasting, and that (ironically enough given their popularity) adding antioxidant supplements counteracts those benefits....

Link between image and sound

by Janet Kwasniak in Neuro-patch

Babies link the sound of a word with the image of an object in their early learning of language and this is an important ability. How do they come to have this mechanism? Are there predispositions to making links between sounds and images? Research by Asano and others (citation below) shows one type of link. […]... Read more »

Vitamin D status affecting autoimmune disease risk?

by Paul Whiteley in Questioning Answers

I want to bring the paper from Tea Skaaby and colleagues [1] to your attention for today's brief blog post and their observation that there may be: "a possible protective role of a higher vitamin D status on autoimmune disease". Autoimmune disease by the way, reflects a breakdown in communication and tolerance of 'self' whereby the body attacks healthy tissue.Their findings, based on an analysis of "a total of 12,555 individuals from three population-based studies with measurements of vitam........
