Polar Bears Stubbornly Stick to Habitats, Even as Ice Melts

by Elizabeth Preston in Inkfish



"I don't know what you're talking about," said the polar bear. "Everything seems normal to me! Watch out for that puddle."

Up in the Arctic, things are getting slushy. But some polar bears are refusing to change their ways. Instead of compromising on where they spend their time, they're clinging to the icy habitats they've always loved. As those habitats keep shrinking, though, the bears will eventually find things too crowded and uncomfortable to ignore. 

Researchers divide polar bear... Read more »

The relationship between low physical activity and psychotic symptoms

by Dr. Jekyll in Lunatic Laboratories

Physical activity can help reduce cardiovascular disease and premature mortality in people with psychological problems. However, there is limited data on exercise in people with serious mental disorders, especially from low- and middle-income countries. This study explored whether complying with the World Health Organization recommendations of 150 minutes of moderate-vigorous exercise per week is related to psychotic symptoms or the diagnosis of a psychosis.

How to rebuild a brain

by gdw in FictionalFieldwork

After the stroke The human brain is complicated. Very complicated. And like any piece of complex machinery that relies on the smooth functioning of many components, it’s not immune to malfunction. When a part of the brain doesn’t get proper nutrition through a nice and smooth blood flow, things go awry and a stroke occurs. […]... Read more »

Hospitalisation for infection and risk of death by suicide

by Paul Whiteley in Questioning Answers

"An increased risk of death by suicide was found among individuals hospitalized with infection in prospective and dose-response relationships. These findings indicate that infections may have a relevant role in the pathophysiological mechanisms of suicidal behavior."Some intriguing data has been recently reported by Helene Lund-Sørensen and colleagues [1] (open-access) examining the possibility that certain types of infection (or perhaps the biological response to infection) might inc........

How long do you want to live? Your expectations for old age matter

by Dr. Jekyll in Lunatic Laboratories

Why do some people want to live a very long time, while others would prefer to die relatively young? In a latest study, a team of researchers investigated how long young and middle-aged adults in the United States say they want to live in relation to a number of personal characteristics. The results showed that more than one out of six people would prefer to die younger than age 80, before reaching average life expectancy.

Epigenetics of Early Pregnancy Loss: Hypomethylation and Genetic Instability May Contribute to Decreased Implantation Potential of Monosomy Blastocysts

by Blair McCallie in EpiBeat

Aneuploidy is the leading cause of miscarriage, stillbirth, and congenital birth defects and occurs as a result of errors during meiotic or mitotic cell division.1 As a woman ages, the probability of an aneuploid conception significantly rises, to roughly 50% by the age of 40.2 Only a fraction of full aneuploidies, primarily trisomies, will develop past the first trimester. This is in contrast to monosomies that almost never implant or result in an ongoing pregnancy. DNA methylation is an epi........ Read more »

Psychopathy Personality Inventory—Revised (PPI-R) Scale 

by Rita Handrich in The Jury Room

We wrote about this scale in our last post when researchers (trying to convince the reader there is such a thing as a good psychopath for you to hire) used it in a study of German adults. The PPI-R is apparently a measure of psychopathy that is able to “detect relatively mild levels of psychopathy […]

ALSPAC says maybe to link between prenatal paracetamol exposure and childhood behavioural difficulties

by Paul Whiteley in Questioning Answers

ALSPAC - the Avon Longitudinal Study of Parents and Children - continues to give in research terms as today I approach the findings reported by Evie Stergiakouli and colleagues [1]. They observed that: "Children exposed to acetaminophen [paracetamol] prenatally are at increased risk of multiple behavioral difficulties, and the associations do not appear to be explained by unmeasured behavioral or social factors linked to acetaminophen use insofar as they are not observed........

Keeping Your “Ion” The Ball – Salts and Life

by Mark Lasbury in As Many Exceptions As Rules

Lost at sea is no way to go to your everlasting reward. Sit in the sunshine too long and you lose your salts and all your functions go bonkers. Drink seawater and you end up with too much sodium and potassium and go nuts. Either way your dead, and it all has to do with your body’s tipping point and the kidney’s function in maintaining an osmotic potential. What is weirder - licorice can cause just about the same problem. ... Read more »

Making Music From Brainwaves: A History

A new paper in Brain tells the story of attempts to turn brain waves into music. The authors are Bart Lutters and Peter J. Koehler: Brainwaves in concert: the 20th century sonification of the electroencephalogram


Electroencephalography (EEG), a technique for measuring brain electrical activity, was invented by German psychiatrist Hans Berger in 1929. Berger's EEG displayed the recorded activity in the form of graphs, using a mobile pen and a rotating drum of graph paper, but within 5 years,... Read more »

Too much activity in certain areas of the brain is bad for memory and attention

by Dr. Jekyll in Lunatic Laboratories

Neurons in the brain interact by sending each other chemical messages, so-called neurotransmitters. Gamma-aminobutyric acid (GABA) is the most common inhibitory neurotransmitter, which is important to restrain neural activity, preventing neurons from getting too trigger-happy and from firing too much or responding to irrelevant stimuli.

A stroke can happen at any age, and as with anything that involves the brain, a few seconds can be life altering. Usually the rule is time lost is brain lost, but there might be some good news regarding that, researchers found that omega-3 fatty acids reduced brain damage in a neonatal mouse model of stroke.
