Post-Operative Kidney Function in Living Kidney Donors vs. Renal Cell Cancer

by Cristy at Living Donor 101 in Living Donors Are People Too

The authors compared 94 pairs of living kidney donors and folks who underwent nephrectomy due a cancerous kidney tumor. Median pre-nephrectomy GFR was nearly equal for both groups. But:   In living kidney donors, median eGFR decreased by 34.4 % immediately after surgery. Compared with matched RN-patients, immediate postoperative [kidney function] is significantly more pronounced.   …

Chlamydia and Cancer: A new connection

by Gabriel in Lunatic Laboratories

Infections due to the sexually transmitted bacterium Chlamydia trachomatis often remain unnoticed. The pathogen is not only a common cause of female infertility; it is also suspected of increasing the risk of abdominal cancer. A new study has now observed the breakdown of an important endogenous protective factor in the course of chlamydial infection. In other words, the pathogen can cause an increased risk of certain cancers.... Read more »

Worm Defies Tradition, Stores Gut Bacteria in Gills Instead

by Elizabeth Preston in Inkfish

What—just because they’re called gut microbes, you’ve been keeping them in your colon? How unoriginal. This is Bankia setacea, also called the Northwest or feathery shipworm. Humans usually pay attention to shipworms only when they perform their namesake activity: burrowing face-first into our boats or docks and eating their way through. Shipworms are bivalves, like clams […]The post Worm Defies Tradition, Stores Gut Bacteria in Gills Instead appeared first on Inkfish.... Read more »

Breaking Research: Lithium may protect against Alzheimer’s and other aging-related diseases

by Bethany Christmann in Fly on the Wall

As human life expectancy continues to increase at a steady rate in most countries worldwide, the prevalence of aging-related diseases is also increasing. One such example is Alzheimer’s disease (AD), the most common cause of dementia in the aging population. There is currently no cure for AD, and the only treatments that exist temporarily cover […]...

Reformers say psychologists should change how they report their results, but does anyone understand the alternative?

The rectangular bars indicate samplemeans and the red lines represent theconfidence intervals surrounding them.Image: Audriusa/WikipediaPsychological science is undergoing a process of soul-searching and self-improvement. The reasons vary but include failed replications of high-profile findings, evidence of bias in what gets published, and surveys suggestive of questionable research practices.Among the proposed solutions is that psychologists should change the way they report their fin........

One fifth of schizophrenia cases linked to Toxoplasma gondii?

by Paul Whiteley in Questioning Answers

"The PAF [population attributable fraction] for schizophrenia in those exposed to T. gondii is tentatively 21.4%". That was the headline conclusion made by Prof. Gary Smith [1] in his modelling analysis estimating what percentage of cases of schizophrenia might involve the protozoan Toxoplasma gondii. Some of the accompanying media about this potentially very important finding can be found here and here.You don't need to study scaring, you just do it.Although no expert on the PAF - defined as [2........

Hard times, tough gods

by Tom Rees in Epiphenom

Almost all cultures have some kind of supernatural beliefs. But it may surprise you to know that belief in moralising supernatural beings, who care about whether mortals do good or bad, are far from universal. That’s fascinating, and it begs the question: “why?”. Why do some cultures bother to believe spirits who watch over us [Read More...]

Limitless: The science behind remembering everything

by Gabriel in Lunatic Laboratories

If you could remember everything, you saw, learned, or did, would it be a blessing or a curse? Well an even better question would be, it even possible to upgrade the storage capabilities of the brain? The answer is strangely enough, maybe, according to a new study we might just be able to remember quite literally everything.

Neurogenesis in “non-neurogenic” regions

by Federico Luzzati in the Node

In the early ‘90s, the discovery of neural stem cells in the adult brain aroused hope to exploit these cells to treat neurodegenerative diseases or even induce brain regeneration. Yet, the real potential of these cells is still unclear. In the last 15 years we have learned that during development neural stem cells are an […]... Read more »

Can I Use Mechanical Turk (MTurk) for a Research Study?

by Richard Landers in NeoAcademic

Amazon Mechanical Turk (MTurk) has quickly become a highly visible source of participants for human subjects research. Psychologists, in particular, have begun to use MTurk as a major source of quick, cheap data. Studies with hundreds or thousands of participants can be identified in mere days, or sometimes, even a few hours.

Babies' anxiety levels are related to their fathers' nervousness, not their mothers'

by BPS Research Digest in BPS Research Digest

Picture a one-year-old infant crawling across a table top. Half way across, the surface becomes transparent so that it appears there is a deep drop. On the other side is the infant's mother or father, encouraging them to crawl across the "visual cliff". Will the baby's anxiety levels be influenced more by the mother's own anxiety or the father's?This was the question posed by Eline Möller and her colleagues in what is the first ever study to examine paternal behaviour in the classic visual........

JUST PUBLISHED: Does Playing Action Video Games Really Improve Your Information Processing?

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

Over the last decade, a number of studies have been published that suggest that playing action video games improves performance on sensory, perceptual, and attentional tasks. For instance, Green, Pouget, and Bavelier (2010) found that playing action video games led to faster information processing, reduced response caution, and no difference in motor responding. These and related findings are sufficiently hot right now that they often make it to popular science outlets like Ted talks (for exampl........ Read more »

Ever wonder how the brain maps our world?

by Gabriel in Lunatic Laboratories

Sometimes we go into automatic, that “new” coffee shop on your way to work you just noticed, well it has been there for weeks. We can gauge where we are from just about anywhere we have already been. Giving directions, well some of us can never do that, yet we can still get from point A to B easy enough. Yet if we were to drive or even walk backwards and the world wouldn’t feel quite right, things would feel and seem just a little weird — not just because we are used to seeing things pas........

Do Rats Have Free Will?

by Neuroskeptic in Neuroskeptic_Discover

New research on the neural basis of ‘spontaneous’ actions in rats could shed light on the philosophical mystery that is human ‘free will’. The study, just published in Nature Neuroscience, is called Neural antecedents of self-initiated actions in secondary motor cortex.
