New Cocktail Turns Adult Cells into Stem Cells

by Gabriel in Lunatic Laboratories

For those of us who were following stem cell news, recently the field had a huge setback when a paper, that offered a cheap and novel way to create stem cells, was retracted from publication. Regenerative medicine aims to replace lost or damaged cells, tissues or organs through cellular transplantation, but the promise to a better life has been hampered. Because stem cells derived from human embryos can trigger ethical concerns, a good solution is reprogramming adult cells back to an embryo-like........ Read more »

Cannabis-induced Paranoia: Cognitive Mechanisms

by William Yates, M.D. in Brain Posts

Some individuals appear vulnerable to paranoia induced by exposure to tetrahydrocannabinol (THC) in cannabis.The mechanism for this effect is poorly understood.Daniel Freeman from University of Oxford along with colleagues in England and Switzerland recently conducted an interventional research study on this issue.In this study, 121 subjects were recruited to receive injections of THC in a laboratory setting.These subjects were required to have taken cannabis at least once before participation i........

Should Policy Makers and Financial Institutions Have Access to Billions of Brain Scans?

by The Neurocritic in The Neurocritic

"Individual risk attitudes are correlated with the grey matter volume in the posterior parietal cortex suggesting existence of an anatomical biomarker for financial risk-attitude," said Dr Tymula.This means tolerance of risk "could potentially be measured in billions of existing medical brain scans." 1 -Gray matter matters when measuring risk toleranceLet's pretend that scientists have discovered a neural biomarker that could accurately predict a person's propensity to take financial risks in ........

The schizophrenias (plural)

by Paul Whiteley in Questioning Answers

A micropost if you will, to draw your attention to the paper by Javier Arnedo and colleagues [1] mentioning the concept of 'the schizophrenias' (plural). Some media coverage of this paper can be found here and here. The crux of the paper is that although currently unified by a diagnostic label, schizophrenia seems to be comprised of various conditions: "caused by a moderate number of separate genotypic networks associated with several distinct clinical syndromes"."... dogs and cats living t........

Religion And Morality: Belief Isn't Better

by Alexis Delanoir in How to Paint Your Panda

It's no secret that when it comes to what the public thinks, atheists are usually at the bottom of the "nice" list. A survey in 2006 found that atheists were the least trusted minority group in America. Similar studies find that atheists are mistrusted and are seen as more immoral than their religious counterparts. But are these views justified? A new study by Hofmann et al. (2014) suggests they aren't, and this conclusion is consistent with other available data.... Read more »

The Genetic Roots of Schizophrenia

by Gabriel in Lunatic Laboratories

I have a friend who lost an eye — not in a war zone like you might suspect given my background — but to his brother. Yes, you read that correctly, his brother tried to kill him and in the process he lost his eye. I’ve told this story before, but whenever new schizophrenia research comes out I feel the need to tell it again. While he has forgiven his brother (partly because not long after, he was diagnosed as schizophrenic), he will not be able to see him again until he is released from pri........ Read more »

Poop Transplants Let Pack Rats Eat Poison

by Elizabeth Preston in Inkfish

Can’t eat poison without dying? Maybe your gut microbes are to blame. Rodents in the Mojave Desert have evolved to eat toxic creosote bushes with the help of specialized gut bacteria. Although scientists had long suspected that bacteria might be key to the rats’ power, they proved it by feeding the rodents antibiotics and ground-up […]The post Poop Transplants Let Pack Rats Eat Poison appeared first on Inkfish....

Pupils benefit from praise, but should teachers give it to them publicly or privately?

by BPS Research Digest in BPS Research Digest

There's a best practice guide for teachers, produced by the Association of School Psychologists in the US, that states praise is best given to pupils in private. This advice is not based on experimental research - there hasn't been any - but on surveys of student preferences, and on the rationale that pupils could be embarrassed by receiving praise in public.Now, in the first study of its kind, John Blaze and his colleagues have systematically compared the effect of public and private praise (al........

Sweating Is The Pits

by Mark E. Lasbury in The 'Scope

New research is delving into the possible negative aspects of antiperspirants and deodorants. A 2014 study indicates that bacterial fauna is altered by the use of antiperspirants and can lead to overgrowth of bacteria that actually produce more foul smelling chemicals. On a more important note, research is showing that aluminum from antiperspirants may contribute to breast cancer growth, including promotion of estrogen hormone production, altered iron metabolism, and increased oxygen radical for........

How to increase children’s patience in 5 seconds

by Richard Kunert in Brain's Idea

A single act increases adults’ compliance with researchers. The same act makes students more likely to volunteer to solve math problems in front of others. Moreover, it makes four-year-olds more patient. What sounds like a miracle cure to everyday problems is actually the oldest trick in the book: human touch. How do researchers know this? […]...

Zinc and copper and autism

by Paul Whiteley in Questioning Answers

The paper by Li and colleagues [1] looking at serum copper (Cu) and zinc (Zn) levels in a group of participants diagnosed with an autism spectrum disorder (ASD) is the source material for today's post. Highlighting how "mean serum Zn levels and Zn/Cu ratio were significantly lower in children with ASD compared with normal cases... whereas serum Cu levels were significantly higher" the continued focus on the metallome in autism carries on at a pace.

JUST PUBLISHED: The Dance of Communication: Retaining Family Membership Despite Non-Speech Dementia

by Mark Rubin in The University of Newcastle's School of Psychology Newsline

As the majority of people in developed countries will be touched in some way by dementia in the 21st century, current ways of interacting in dementia care may no longer be acceptable. In particular, when people with dementia appear uncommunicative, their retained awareness and ability to interact is often dismissed or overlooked. Facing social isolation and further decline, many languish with unmet needs for human interaction. However, the intimacies of family interaction in dementia care settin........ Read more »
