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 »

Fright Week: The Waking Nightmare of Lord Voldemort

by The Neurocritic in The Neurocritic

Nightmares can seem very real at times, but then we wake up and realize it was all a bad dream. Now imagine having a vivid nightmare with all the reality of waking life and then... it turns out you're actually awake through it all!This happened to an 11 year old Italian boy who reported frightening auditory and visual hallucinations of Voldemort, the archenemy of Harry Potter, for three straight days. These hallucinations began after a bout of sore throat and fever (38°C).  As Vita et........ Read more »

The Oceans Link to Climate Change

by Gabriel in Lunatic Laboratories

Hold on to your hats folks, we can all agree that most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new study a group of researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. Keep in mind this doesn’t mean global warming isn’t a man-made problem, please.... Read more »

Autism and intolerance of uncertainty

by Paul Whiteley in Questioning Answers

Good morning, gentlemen, the temperature is 110 degrees'Change' is often mentioned as something potentially problematic for many on the autism spectrum, and how unexpected change can sometimes have profound effects in terms of those so-called 'challenging behaviours' or when it comes to the presentation of important comorbidity such as anxiety. Like many others from the outside looking in, I was always taught that change as a more general concept was the important issue in autism, but recently t........ Read more »

The Genetics of Congenital Heart Defects Slowly Emerge from Down Syndrome Study

by Gabriel in Lunatic Laboratories

Down syndrome, of all the genetic defects people are born with, is the most common (as far as chromosomal abnormalities go). Down syndrome involves having a third copy of all or part of chromosome 21 (for those who do not recall we are typically born with 23 pairs of chromosomes). In addition to intellectual disability, individuals with Down syndrome have a high risk of congenital heart defects. However, not all people with Down syndrome have them – about half have structurally normal hearts.... Read more »

Fish Want to Play Too

by Elizabeth Preston in Inkfish

Yes, fish. These aquarium lap-swimmers and pursuers of flaked food aren’t known for their joie de vivre. Yet in one hobbyist’s tanks, scientists say they’ve captured a rare instance of fish playing around. James Murphy is a herpetologist at the Smithsonian National Zoological Park. Although he professionally studies reptiles and amphibians, he keeps fish as […]The post Fish Want to Play Too appeared first on Inkfish.... Read more »

Breaking Research: WIDE AWAKE is a newly identified gene that explains how we become sleepy at night

by Bethany Christmann in Fly on the Wall

The body’s biological clock is responsible for keeping track of time and synchronizing behavior with the environment, so that you feel alert during daylight hours and sleepy at night. This biological clock (also called the circadian clock or circadian rhythms) consists of three major parts: The central pacemaker, which oscillates with a period of about […]... Read more »

Publication bias afflicts the whole of psychology

by BPS Research Digest in BPS Research Digest

In the last few years the social sciences, including psychology, have been taking a good look at themselves. While incidences of fraud hit the headlines, pervasive issues are just as important to address, such as publication bias, the phenomenon where non-significant results never see the light of day thanks to editors rejecting them or savvy researchers recasting their experiments around unexpected results and not reporting the disappointments. Statistical research has shown the extent of this ........ Read more »

There is a party going on at the ends of microtubules, but I wasn’t invited. That won’t stop me, or countless cell biologists out there, from peeping in the window to check out all of the microtubule shenanigans. Today’s image is from a paper describing how Doublecortin binds to microtubule ends.The plus end of a microtubule is the primary site for growth and shrinkage, and interaction with several microtubule-associate proteins. Different microtubule end-binding proteins may interact with........ Read more »

Autism, siblings and DSM-5 Social Communication Disorder

by Paul Whiteley in Questioning Answers

A quick post to bring to your attention the paper by Meghan Miller and colleagues [1] who concluded that: "Pragmatic language problems are present in some siblings of children with ASD [autism spectrum disorder] as early as 36 months of age". Further: "As the new DSM-5 diagnosis of Social (Pragmatic) Communication Disorder (SCD) is thought to occur more frequently in family members of individuals with ASD, it is possible that some of these siblings will meet criteria for SCD as th........

The Genes Responsible for Immune System Reset after Infection

by Gabriel in Lunatic Laboratories

We’ve all been sick before, the aches and pains that come with it– most of the time including a fever — are all responses to our immune system kicking into high gear. But what if your body didn’t reverse course and go back to a, let’s call it” relaxed state.” Once the battle is won, the body’s efforts would be wasted on energy costing defense. A bad thing when the body really should be focusing on repairing the damage done by the foreign invaders.... Read more »

Trick-or-Treating: What Do You Hand Out On Halloween?

by Melissa Chernick in Science Storiented

Halloween is almost here. And you know what that means: Candy! It’s one of those Halloween traditions that I just never seem to have grown out of. Those little chocolate bars are seriously dangerous to my waistline. Remember how much Halloween candy you ate when you were a kid? Were you one of those kids who gorged on all that sugary goodness, or were you the type to parse it out and make it last? I was a Trader, that kid that made deals to trade all her bad candy for the good stuff. Anyway, t........ Read more »
