by Erin Campbell in HighMag Blog

I’m still waiting for my miniaturizing spaceship* so I can dive into a cell with my dog and ride in the lamella of a crawling cell. Until then, I will gladly enjoy images like today’s, from the Lippincott-Schwartz lab. A cell’s shape can change for many reasons, including crawling, tissue regeneration, and cancer progression. Cell shape is dynamic, relying on temporal and spatial coordination of several processes. The three-dimensional nature of cell shape, however, presents a challenge........ Read more »

Quantum Dots Open Way For Solar Windowpanes

by Whitney Campbell in Green Screen

Recently scientists at Los Alamos National Laboratory and the University of Milano-Bicocca showed how, some day with the same surface, we may be able to see the sun and glean it too. By redesigning a light-grabbing nanocrystal, these material researchers devised a technique that could change sheer Plexiglas sheets into large-area solar concentrators.1... Read more »

Addiction is like diabetes, so treat it the same way

by DJMac in Recovery Review

Does addiction behave like diabetes? In some ways, yes. The two are common, acquired conditions influenced by genetics and environment. In the UK, diabetes is managed in primary care using the chronic care management model. Changes in legislation in the USA mean that there will be more focus on chronic disease management in the future. [...]... Read more »

Recovery too hard? Methadone for life!

by DJMac in Recovery Review

Berlin, like many big cities has a heroin problem. People presenting for help are being prescribed opioid replacement therapy (ORT) in greater numbers. That’s a good thing isn’t it?

What You Need To Know About The New Ebola Outbreak

by Rebekah Morrow in United Academics

Recent outbreaks of Ebola virus in Guinea have made international news. Ebola virus was first identified in 1976 in the region that is now the Democratic Republic of the Congo in central Africa. The virus was named after the river near where it was found. Since 1976, there have been multiple outbreaks in central Africa, but this year is the first time that an outbreak has occurred as far west as Guinea and Sierra Leone.... Read more »

"GI [gastrointestinal] dysfunction was prevalent in this cohort of children with ASD [autism spectrum disorders], observations consistent with the reports of parents and other clinicians". That was one of the conclusions reached by Victor Kang and colleagues [1] in their study looking at GI issues in cases of autism.Of course we've been here before... many times in fact, as autism research delivers more evidence that bowel issues are quite frequently over-represented in cases of autism........

Is interceptive orthodontics a hopeless pipedream?

by Kevin OBrien in Kevin OBrien's Orthodontic Blog

Is interceptive orthodontics a hopeless pipedream? In this blog I will address another of the “great unanswered questions” in orthodontics that featured in a previous blog. This is the long-standing issue of whether it is possible to provide interceptive orthodontics and either “cure” orthodontic problems before they develop or make any eventual treatment easier. This […]

What Is A Typical Animal Hoarder?

Sometimes we hear their cases on the news – dozens of sick and frightened dogs or cats removed from the home of an animal hoarder. But is there a typical profile, and how big is the problem?A study by Calvo et al (2014) investigates 24 cases of animal hoarding in Spain between 2002 and 2011. Photo: schankz / ShutterstockAnimal hoarding is not simply having large numbers of pets; it also involves a lack of care for those pets, such that they are sick, not receiving veterinary care and livi........

Chili Peppers Run Hot And Cold

by Mark Lasbury in As Many Exceptions As Rules

Hot peppers are hot because their capsaicin binds to the TRPV1 heat sensing ion channel. Agonists of TRPV1 can lead to a hypothermia, while antagonists result in a hyperthermia. Normally these would be poor outcomes, but there are particular instances that new researchs are showing to be beneficial. Brown adipose tissue is promoted by TRPV1 agonists, and studies are showing that capsaicin can hinder formation of white adipose tissue. Likewise, agonists of TRPV1 can induce a protective hypothermi........ Read more »

How can I convince them this wasn’t racist? Just keep talking…

by Doug Keene in The Jury Room

We just can’t keep up with all the research on racism. So today, instead of a single article, we’re going to cite 3 of them! They are all disturbing examples that racism is alive, well, and measurable.  Was s/he a good professor? We’ve all sat through disorganized and incoherent lectures at some point in our […]

How ginseng works against flu

by Patricia Pedro in United Academics

Not that long ago, I heard about ginseng in my Plants’ Diversity class, but it was not given that much relevance.

Why are some syllables preferred?

 In a recent paper by Berent and others (citation below) they investigate language universals in syllable structure.

Phenylalanine and schizophrenia: new directions for intervention?

by Paul Whiteley in Questioning Answers

As regular readers might already have noticed, amino acids are a bit of a obsession of mine on this blog. Out of all of them - and there are quite a few - I'm particularly interested in the aromatic amino acids and the their various connections to health and wellbeing. I've talked at length about some of the proposed connections made between amino acids such as tryptophan, tyrosine and phenylalanine to all manner of conditions but specifically with the autism spectrum in mind (see here).The conv........
