One Thing Is Just Like The Other – Sort Of

by Mark Lasbury in As Many Exceptions As Rules

Recent studies have illustrated how complicated evolution by descent with adaptation can be. Convergent evolution and parallel evolution explain the fingerprints of koalas and the marsupial and placental saber-toothed cats. Dollo’s Law of Irreversibility has been shown to be plastic, as frogs have re-evolved mandibular teeth and stick insects have lost and regained wings several times. ... Read more »

Maternal complement C1q and offspring psychosis

by Paul Whiteley in Questioning Answers

"In conclusion, exposure to maternal C1q activity during pregnancy may be a risk factor for the development of schizophrenia and psychosis in offspring". That was the primary observation made by Emily Severance and colleagues [1] at Johns Hopkins, extending their scientific interest in immune system involvement being potentially linked to psychiatry [2]."Serve the public trust, protect the innocent, uphold the law"I've already talked about Dr Severance's previous research forays into complement ........

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 »

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........

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 »

Term vs. preterm birth and the presentation of autism

by Paul Whiteley in Questioning Answers

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 »

Yes, people with autism do have headaches

by Paul Whiteley in Questioning Answers

I don't mean to be haughty but a sentence included in the paper by Victorio [1] led to the title of today's very quick post. Based on a chart review of patients diagnosed with an autism spectrum disorder (ASD) attending a neurology clinic, the author concluded that "ASD patients, despite being known to have indifference to pain, can experience headaches".Pain is something which has cropped up quite a bit in the autism research arena and has appeared more than once on this blog (see here and see ........

“GMO” Foods (Once Again) Proven Safe

by Gabriel in Lunatic Laboratories

GMO, I shudder every time I hear someone talk about the “dangers”. It’s one of the new buzzwords that doesn’t actually mean anything, but still manages to scare people. Well a new scientific review reports that the performance and health of food-producing animals consuming genetically engineered feed, first introduced 18 years ago, has been comparable to that of animals consuming non-GE feed. Not that this will stop people from spreading fear, but it’s a start.... Read more »

Walking Really Is Just Falling and Catching Yourself

by Elizabeth Preston in Inkfish

The flailing of a gymnast who’s missed a step on the balance beam might not be far off from what the rest of us experience every day. Each step we take is really a tiny fall, a mathematical model suggests. The random-looking variation in our footfalls is actually a series of corrections. Our strides are […]The post Walking Really Is Just Falling and Catching Yourself appeared first on Inkfish.... Read more »

Anthropomorphic Neuroscience Driven by Researchers with Large TPJs

by The Neurocritic in The Neurocritic

For immediate release — SEPTEMBER 26, 2014Research from the UCL lab of Professor Geraint Rees has proven that the recent craze for suggesting that rats have “regrets” or show “disappointment” is solely due to the size of the left temporal-parietal junction (TPJ) in the human authors of those papers (Cullen et al., 2014). This startling breakthrough was part of a larger effort to associate every known personality trait, political attitude, and individual difference with the size of a un........ Read more »

September 25, 2014

by Erin Campbell in HighMag Blog

While taking an awesome cell biology course in college, I was coming to terms with my mother’s recent ovarian cancer diagnosis. The scientist in my head couldn’t shake the curiosity about how my mother’s cells could have betrayed her so royally. This intersection of basic cell biology and cancer kick-started my interest in cell biology research. Today’s image is from a paper showing a role for the ARF tumor suppressor in maintaining chromosomal stability. THIS paper is one of the mil........ Read more »

A New Discovery in the Treatment of Autoimmunity and Chronic Inflammation

by Gabriel in Lunatic Laboratories

Lupus, Type 1 diabetes, and multiple sclerosis are all diseases brought on by autoimmunity — the bodies inability to tell itself apart from foreign invaders. Finding a cure, or even a suitable treatment has been to put it gently a long, painful road, with little to show for it. On the forefront of the war against the body betrayal is immunosuppressants, which with them carry their own set of side effects and in most cases only off mild to moderate relief of symptoms. But that is all changing a........ Read more »
