Male dragonflies are not as violent as thought

by Piter Boll in Earthling Nature

by Piter Kehoma Boll Males and females are defined by their gametes. Males have tiny, usually mobile gametes, while females have very large gametes that usually do not move. This means that females produce less gametes, but put a lot … Continue reading →... Read more »

Deductive, Inductive and Abductive Research in SCM

by Andreas Wieland in Supply Chain Management Research

Like it or not: Our discipline is very much dominated by positivism and the application of the scientific method, which assumes that new knowledge can be created by developing and testing theory or, in other words, by induction or deduction. Another type of inference is abduction. Spens & Kovács (2006) present an overview of the […]... Read more »

CRISPR-Cas9 and autism research

by Paul Whiteley in Questioning Answers

If you feel brave enough, today I will direct your reading attention to the paper by Michael Williams and colleagues [1] detailing the application of a particularly important genome editing technique called CRISPR-Cas9 [2] to autism-related science.Titled: "A Retroviral CRISPR-Cas9 System for Cellular Autism-Associated Phenotype Discovery in Developing Neurons" the Williams paper probably won't win any awards for plain English but don't be fooled about just how important this pape........

Humiliation from stares are worse than tiny seats for obese air travelers

by Dr. Jekyll in Lunatic Laboratories

Feelings of shame and humiliation bother obese air passengers more than tight seat belts and tiny seats, according to a study published by Ben-Gurion University of the Negev (BGU) researchers. Participants interviewed for the study recounted the typical challenges they encounter while boarding, in-flight and deplaning.

Open Access reviewed: stricter criteria preserve credibility

by SciELO in SciELO in Perspective

The most comprehensive index of open access journals, the Directory of Open Access Journals (DOAJ), reviewed its inclusion criteria, in view of allegations of the presence of predatory journals. This restructuring will lead to more than 3,000 journals to be removed from the database. DOAJ, besides advocating Open Access, established, in collaboration with COPE, OASPA and WAME, a code of principles and good practices in scientific publishing. … Read More →... Read more »

A New Chromosome Y Risk for Alzheimers

by William Yates, M.D. in Brain Posts

There are many risk factors for Alzheimer's Disease (AD) including history of head trauma and family history of AD.The strongest risk factor is advanced age. Yearly risk for AD is about 1% per year in 70 year old populations jumping to around 7% in 90 year old groups.Now a recent study is shedding some light on a new risk for AD in men. This risk appears to be related to a chromosome Y phenomenon known to be associated with aging.Elderly men show a tendency to lose the Y chromosome from a small ........ Read more »

Minimalist, anonymous rooms are probably not a good place to do teamwork

by BPS Research Digest in BPS Research Digest

According to the philosophy of "lean space management", a minimalist workspace shorn of clutter is distraction-free and ideal for productivity. But this philosophy turns out to have slim empirical foundations, and as promoting a sense of identity at work, including personalising the work space, generally leads to better outcomes, there’s reason to expect richer, characterful workplaces to be more beneficial. A new article in the Journal of Personnel Psychology builds on this past work, showing........ Read more »

Position Someone to Guard Against Bad Laxity Measures

by Nicole Cattano in Sports Medicine Research (SMR): In the Lab & In the Field

Knee flexion to 90 degrees limits ankle laxity with the talar tilt test in comparison to a fully extended knee. However, knee position has no effect on anterior drawer laxity. Muscle guarding will limit our ability to accurately assess ankle laxity with a talar tilt or anterior drawer test. ... Read more »

The persistence of self-injury in relation to autism

by Paul Whiteley in Questioning Answers

Some behaviours associated with a diagnosis of autism don't make for great dinner table discussion. Self-injurious behaviours (SIBs), as exemplified by head banging, hair pulling and eye gouging must rank as some of the more distressing facets of [some] autism insofar as their potential effect on the person and also the people around them.These and other types of behaviour commonly headed under the category of so-called 'challenging behaviours' have tended not to be too evident when it come........

Hatching Sea Turtles Get a Hand from Their Siblings

by Elizabeth Preston in Inkfish



Smashing out of its egg is only the first step in a baby sea turtle's grueling early days. The turtle fights free of its eggshell only to find itself buried underground. It has to intuit which way is up, then dig out of the packed sand. As soon as it breaks onto the surface of the beach, it begins a mad sprint to the ocean. All around are its brothers and sisters, flailing toward the water as fast as their own flippers will carry them. In the sea they'll keep swimming frantically, trying ........ Read more »

The James Earl Jones (or Barry White) Effect now applies to women too! 

by Doug Keene in The Jury Room

Almost five years ago, we wrote about research saying men with deep voices were more persuasive. Science has moved forward though and now, women can also be more persuasive when using a deeper voice. Some call it a “sultry voice”. New work tells us your voice doesn’t have be a deep and resonant baritone to […]

A critical comment on “Contextual sensitivity in scientific reproducibility”

by Richard Kunert in Brain's Idea

Psychological science is surprisingly difficult to replicate (Open Science Collaboration, 2015). Researchers are desperate to find out why. A new study in the prestigious journal PNAS (Van Bavel et al., 2016) claims unknown contextual factors of psychological phenomena (“hidden moderators”) are to blame. The more an effect is sensitive to unknown contextual factors, the less […]... Read more »

ZIKV infection in mice: cell cycle defects as a cause for microcephaly?

by thelonevirologist in Virology Tidbits

Zika Virus (ZIKV) was first isolated in 1947 from a sentinel monkey in Uganda and despite sporadic local outbreaks only caused mild disease in humans. The emergence of ZIKV combined with severe pathogenicity in South America as early as 2014 however raised questions about the molecular evolution of ZIKV since ZIKV was previously only associated with arthralgia and a mild febrile illness but not neuropathological disorders including abnormal foetal brain development and Guillan-Barre Syndrome (GB........

Does Flu Vaccination Reduce Dementia Risk?

In my daily review of neuroscience news I ran across an article flu vaccination and dementia risk in heart failure.This study was reported at the 3rd World Congress on Acute Heart Failure by Dr. Ju-Chi Liu from Taipei Medical University.So how might influenza vaccination be related to dementia risk?  We do know acute influenza infection reaches the brain causing headache and increasing brain inflammation, at least temporarily. We also know brain inflammation may be involved in the mechanism........ Read more »
