A Warm Winter Legacy: Leaf Flushing and Senescence Long-Term

by Melissa Chernick in Science Storiented

Fall is in the air. Here in North Carolina that means drastic temperature swings that cause me to dress incorrectly on any given day. It also means the arrival of fall colors. Indeed, fall colors are incredibly beautiful, but biologically speaking, you are watching death happen. This autumn splendor got me to thinking about these colors a little closer, specifically the phenology of trees.Phenology is the study of the annual timing of recurring life cycle events. The timing of these events is t........ Read more »

New Immune System Discovery

by Gabriel in Lunatic Laboratories

The immune system is sort of this big enigma, we know how pieces of it work, but we don’t know it as well as we would like or we wouldn’t have autoimmunity to contend with. Well new research reveals new information about how our immune system functions, shedding light on a vital process that determines how the body’s ability to fight infection develops. Which brings us one step closer to the big picture of the immune system.... Read more »

The Evidence from DNA

by teofilo in Gambler's House

To wrap up my series on tracing the connections between ancient Pueblo sites like Chaco Canyon and the modern Pueblos, I’d like to discuss a type of evidence I haven’t discussed much but that people often ask about: DNA evidence. This is the most direct way to tie one population to another, at least in theory, […]... Read more »

Autoimmune thyroiditis and depressive disorder

by Paul Whiteley in Questioning Answers

"Our study demonstrates a strong association between anti-TPO levels, which are considered to be of diagnostic value for autoimmune thyroiditis... with uni- or bipolar depression.""Beware the bad cat bearing a grudge"So said the study published by Detlef Degner and colleagues [1]. Anti-TPO antibodies by the way, refers to anti-thyroid peroxidase antibodies which, as the name suggests, are antibodies against thyroid peroxidase, an important step in the production of thyroid hormone........

Conscious content

by Janet Kwasniak in Neuro-patch

I have been thinking about some information in a not too recent paper. (see citation below) Panagiotaropoulos and others looked at the location of the content of consciousness in primates. They used binocular flash suppression (BFS) to give two different visual stimulation that compete for a place in the content of consciousness. Here is their […]... Read more »

Cat and Dogs: seeking solutions with sniffing canines and science

by Cobb & Hecht in Do You Believe In Dog?

Hi Mia and Julie,  First of all, I LOVE your blog! After meeting at SPARCS this past summer (summer for us in North America.. I take it summer is just beginning in Australia!), I’ve followed it closely.  You do amazing things for the promotion of  canine science. Serious love. A bit of background for the readers: I’m currently doing my PhD at Dalhousie University in Halifax, Nova Scotia in Canada, under the supervision of Dr. Simon Gadbois. Dr. Gadbois........ Read more »

New Protein Implicated in Alzheimer’s

by Gabriel in Lunatic Laboratories

Alzheimer's prevention has made some strides in recent years. We've even identified some new causes, and in some cases we can do both. In fact, researchers have now shown that low levels of the protein progranulin in the brain can increase the formation of amyloid-beta plaques (a hallmark of Alzheimer's disease). These plaques can cause neuroinflammation, and worsen memory deficits in a mouse model of this condition. Conversely, by using a gene therapy approach to elevate progranulin levels, sci........

Wind Turbines Kill Bats by Impersonating Trees

by Elizabeth Preston in Inkfish

Survival tip: don’t hang around machines that have giant spinning blades. It’s a lesson bats have been slow to learn, judging by the large numbers of their corpses found beneath wind turbines. New video footage suggests some bats are attracted to wind farms because they can’t tell turbines apart from trees. If it’s true, this […]The post Wind Turbines Kill Bats by Impersonating Trees appeared first on Inkfish.... Read more »

Family Attachment and the Brain Cingulate Cortex

by William Yates, M.D. in Brain Posts

Healthy family attachment provides a key element for social support and successful interpersonal relationships.Several brain regions as well as hormonal factors appear to modulate positive emotional responses to family members.I have previously reviewed several studies involving the prosocial effects of the hormone oxytocin and the related hormone vasopressin.Nicolas Rusch from the Department of Psychiatry at Ulm University in Germany along with colleagues in Brazil and London recently published........

Eye contact makes us more aware of our own bodies

by BPS Research Digest in BPS Research Digest

If you've ever felt acutely self conscious upon making eye contact with another person, a new study may help you understand why. Matias Baltazar and his colleagues have found that making eye contact activates people's awareness of their own bodies. That feeling of self consciousness induced by mutual gaze might be based in part on the fact that your brain is suddenly more attuned to your body.The researchers presented 32 participants with a series of positive and negative images on a computer sc........

Simple Jury Persuasion: Should you consider 3-D for your courtroom videos?

by Doug Keene in The Jury Room

Evidence admissibility issues aside, the answer is, “only if you can do it as well as they did in the 3D movie Polar Express”. As it turns out, 3D isn’t that much more impactful than 2D unless it’s done really, really well. Psychologists and neuroscientists studying emotion often use film clips for their research. So […]

Term vs. preterm birth and the presentation of autism

The paper by Katherine Bowers and colleagues [1] continues the interest in the concept of 'the autisms' with their observations on the presentation of autism (and its comorbidities) when looking at those "born preterm versus those born at term".We'd better get back, 'cause it'll be dark soon, and they mostly come at night... mostlyBased on an analysis of quite a healthy participant number heading up to 900 "males and females with autism spectrum disorder", authors reported on several phenotypic ........

The Genetic Evolutionary Arms Race

by Gabriel in Lunatic Laboratories

Genes are tricky little buggers, the stuff that makes us up has fought the test of time to make it to where we are today. It is thought that our genes changed in an attempt to outpace other life, albeit random changes.That might only be half right however, new findings suggest that there is an evolutionary arms race going on within the genome against, of all things, itself. This inherent competition of primates drove the evolution of complex regulatory networks that orchestrate the activity of ........ Read more »

Numbers on a scale: How bad did you say your pain was?

How to Look for Pine Marten

by Denise O'Meara in Denise O'Meara

The pine marten (Martes martes) is one of Ireland’s most beautiful but elusive mammals. It is notoriously difficult to see as it tends to be mostly nocturnal, and is a naturally shy animal. It is about the size of a cat, and in Irish it is actually called the tree cat (cat crainn). The species historically suffered massive population declines due to forest removal in the 16th Century and pine marten were also trapped and killed for their fur, which was worn by the nobility across Europe. I........ Read more »
