Converting Skin Cells to Neurons: A Fight Against Huntington’s

by Gabriel in Lunatic Laboratories

Neurological diseases are some of the hardest to fight against (in my opinion). The big reason is the brain, we still know so little about it and treatment for anything effecting it can be difficult to say the least. Take Huntington’s disease, an ultimately fatal neurodegenerative disorder. There is no cure and no real treatment, but that might change relatively soon thanks to a new discovery.... Read more »

Video Tip of the Week: SeqMonk

by Mary in OpenHelix

Always on the lookout for effective visualization tools, I recently came across a series of videos about the SeqMonk software. It’s not software that I had used before, so I wanted to look at the videos, and then try it out. It downloaded quickly, offered me an extensive list of genomes to load up, and […]... Read more »

Death By Haunted House

by Mark Lasbury in As Many Exceptions As Rules

People enjoy a good scare at Halloween, it’s an epinephrine rush without the bother of real danger. But could you actually be scared to death? Science says yes, it should really be called the fight, flight, faint, or fatality response. In susceptible people, a severe fright can literally change the shape of the heart and destroy the efficient pumping of blood. Unfortunately, something similar can happen in infants, and it can be lethal as well.... Read more »

Autism, parental concerns and socioeconomic status

by Paul Whiteley in Questioning Answers

I'd like to think that there are some rather important messages to be taken from the paper by Xiang Sun and colleagues [1] on level of parental concern, socioeconomic status (SES) and risk of autism. Not only did the authors conclude that: "a higher SES was not associated with the risk of having ASC [autism spectrum conditions]" they also found that: "No child met ASC criteria where parents expressed no concerns".Do you prefer "fashion victim" or "ensembly challenged"?SES - including variab........

Not Quite Dead Yet

by Mark E. Lasbury in The 'Scope

History shows that premature burial was more common than people might want to believe. Many burial traditions, including the Irish wake, stem from trying to prevent someone from being buried alive. How might this happen? Several medical conditions can lead to a poor decision on burial time. ... Read more »

Antibiotics and childhood obesity: a weighty correlation

by Paul Whiteley in Questioning Answers

It's been a few weeks since the publication of the paper by L. Charles Bailey and colleagues [1] correlating early multiple exposure to broad spectrum antibiotics with obesity in infancy. On purpose I've left it a while before talking about this research so as to let the scientific dust settle a little and get a flavour for some of the discussions about this research (see here and see here).You're a true vulgarian, aren't you?A few details about the Bailey study first:Looking at the el........

Reasons for visiting ER by those with autism

by Paul Whiteley in Questioning Answers

ER - Emergency Room - or as we call it here in Blighty Accident & Emergency (A & E), is never a particularly desirable place to visit given the emphasis on illness or injury of yourself or loved one. That being said, staff there do a sterling job sometimes under very stressful circumstances, responding to all-manner of complaints, some of which are life-threatening.The paper by Dorothea Iannuzzi and colleagues [1] sought to identify some of the medical reasons why ER visit........

DNA Nanotech: The First Large DNA Crystals

by Gabriel in Lunatic Laboratories

DNA is the stuff of life as we know it, but it is the potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology, and more. Researchers have been working to master the ability to coax DNA molecules to self assemble into the precise shapes and sizes needed in order to fully realize these nanotechnology dreams. A dream that been going on for 20 years now and was just realized.... Read more »

Ten years into the making, the HIV-1 mosaic vaccine finally goes into human trial

by EE Giorgi in CHIMERAS

© Bette Korber et al. I hope you will all forgive me if this week I'm gushing over my amazing mentor Bette Korber, as last week she shared some awesome news on Facebook:"A landmark in my life happened yesterday, a major step in a long story.

New Genetic Test to help Solve Rare Disease Diagnosis

by Gabriel in Lunatic Laboratories

My sister suffers from a rare disease which causes small fiber polyneuropathy, or the killing of nerves in her hands and feet. As it progresses she has trouble standing or using her hands. If that was the worst of it, then it might be liveable given the time between severe attacks is years or more. Unfortunately, it also causes intense and mostly constant pain and burning sensations, pain so bad that conventional narcotic painkillers have trouble controlling it. After some time working with the ........ Read more »

Immunoglobulin E: not just a bystander in lupus?

More epigenetics, EN-2 and autism... the plot thickens

by Paul Whiteley in Questioning Answers

I don't mind admitting that I was to some extent 'winging it' with my previous post on epigenetics and Engrailed-2 (EN-2) as a consequence of the findings reported by Jill James and colleagues [1] with autism in mind. Although an avid follower of the science of epigenetics when (cautiously) applied to autism, I am by no means any authority on the subject matter particularly when it comes to the nitty-gritty details. You can probably therefore expect similar things in my latest discussi........ Read more »

Full-term developmet of quail chick by ICSI

by Mizushima S in the Node

The eggs of domestic birds have been used in the study of developmental biology, leading to the extensive accumulation of knowledge on embryonic development. However, the early events involved in bird development, particularly the mechanism underlying fertilization, have not been elucidated in as much detail as those of other species of animals. The ooplasm in […]... Read more »

A look at Air Pollution and Your Body

by Gabriel in Lunatic Laboratories

We have all probably seen stories from China on the horrid air pollution there. Accompanying those reports of course are the statistics for air pollution that deaths have caused. For the record, the World Health Organization estimated that ambient air pollution caused 3.7 million premature deaths (worldwide) in 2012 alone – yet what exactly happens to your body when it encounters pollutants?...

by Erin Campbell in HighMag Blog

For years the prettiest cells to image were flat cells in a dish. Thanks to the tireless work of many, beautiful high-resolution images can now come from tissue in a living organism. Today’s image is from a paper showing improved techniques for imaging fine cellular processes within large volumes, from the lab of recent Nobel prize winner, Eric Betzig. A material’s refractive index refers to how light travels through it; the simplest example being how light bends when passed through wat........

People Are More Swayed by Things That Look Sciencey

by Elizabeth Preston in Inkfish

Anyone who’s paged through a women’s magazine will recognize this strategy: to make a product seem better, surround it with a scientific glow. “Clinical trials show lashes grow up to 400% fuller!” “27% reduction of dark spots in 10 weeks!” “Ceramides!” Does this actually help convince people to hand over their cash? A study using […]The post People Are More Swayed by Things That Look Sciencey appeared first on Inkfish.... Read more »

Altered ghrelin levels in boys with autism

by Paul Whiteley in Questioning Answers

"Honey, it's the '90s, remember?"Saudi Arabia and autism research? It must be at least one author from the research tag-team that is Mostafa and Al-Ayadhi.Indeed, in today's post it is Laila Al-Ayadhi featured on the paper by Felwah S. Al-Zaid and colleagues [1] (open-access) who concluded on: "a potential role for the hormone ghrelin in the pathogenesis of autism".Ghrelin, by the way, is often called the 'hunger hormone' as a result of its effects in relation to energy homoeostasis.
