One Paragraph on Smart Drugs


Modafinil (a stimulant drug normally used to treat narcolepsy, to help people with sleeping disorders to stay awake) could soon become the new “smart drug” according to a review published in European Neuropsychopharmacology. Neuroenhancement is the term used to describe the targeted enhancement and extension of cognitive and affective abilities based on an understanding of their underlying neurobiology. The FDA-approved drug modafinil, has been heavily researched for cognitive modulation in healthy humans, and appears safe for widespread use. Their review on the cognitive effects of the “smart pill” modafinil has found that it can improve the performance of healthy people on cognitive tasks, meaning it can be considered the first of these “neuroenhancement agents”.

New year, new ideas and a New Logo!

I'm starting this second year on my blog, trying to come up with new ways to grow Crystals and Catalysts and create content that you will like at the same time.

Starting with: One Paragraph Science.....

Starting from next week. Mondays, Tuesdays & Wednesdays, I will be posting new news in science but in  a new and different way. This is called One Paragraph Science where I will be condensing down news in science (obviously) to just one paragraph, whilst maintaining its meaning and keeping them, short, snappy and straight to the point.

This idea I believe, is a great challenge for me because condensing down a long piece of complex research is way harder than it looks.

New logo..?

Yes,  I've made a brand new, shiny, more professional logo to go with Crystals And Catalysts. I hope everyone likes it as much as I do. :)

5 Health Myths Everyone Follows Today: Corrected! | In Arabic

In this past year, my blog has been seen internationally in countries I would have never even dreamed of being seen in (which I think is absolutely amazing). My first priority for this blog is to ensure that everyone enjoys reading my new posts and understands them really well. I even have a google translate button in the sidebar. But as we all know, sometimes (or more often than not) google translate doesn’t always correctly translate text in the ways its supposed to be.
I'd like to thank a really good friend of mine, who has offered to translate one of my blog posts in Arabic so that my blog could reach more corners of the earth.
Enjoy!

Researchers find a new way to cure MRSA

MRSA (methicillin-resistant-staphylococcus aureus) is a type of bacteria which is resistant to a number of widely used antibiotics, therefore making it one of the most difficult to treat bacterial infections.

Nanotechnology creates a super-plaster for diabetes patients.

Individuals with diabetes mellitus are more susceptible to wounding and often suffer from botched wound healing. Today, scientists in Egypt have produced antibacterial nanofibres of cellulose acetate laden with silver that could be used in a new type of bandage to promote tissue repair. Published in the journal of International Journal of Nanoparticles, the scientists reveal details of the new materials and their properties.

FDA Approves 1st Drug Produced By 3D Printing

For years, scientists have been searching for a way to simplify the way drugs are made, making everything computerised, with minimal human interaction as possible. Previously I have reported on a new technology called molecular printing, click HERE to read it first.

Now for the first time, the FDA has approved the first prescription drug made via the new and similar technique: 3D printing.

Follow your #DNATrail

DNA. DNA is the delicate and intricate molecule that decides everything about us. Who we are. What we'll look like. And most importantly: our health. DNA is all our details and information stored into a delicate molecule.
DNA trail 
This summer you can take part in an extraordinary event across London, in support of Cancer Research UK, there are over 21 DNA double helix sculptures scattered across London. They will be up until the Sunday 6th September 2015, then they will be auctioned by Christie's at the end of September.

How many sugars in your tea? – The effect of sugar on water structure and taste.

New research published in the University of York shows that sugar has a significant effect in reducing the bitterness of tea and coffee, particularly by manipulating the essential chemistry.


Sugar has a strong way of affecting chemical “water structure” and this enables it to suppress the bitter taste of tea. The researchers also look into how sugar is able to change the structure of caffeine – when it has additives and without additives.

Link Found between Depression and Intestinal Bacterium

Scientists have found that intestinal bacteria play an important role in inducing anxiety and depression.

Published in Nature Communications, the new research is the first of which studies the role of intestinal microbiota in the altered behaviour that is a consequence of early life stress. Previously there has been little research on this subject. All scientists knew was that intestinal bacterium can affect behaviour, but this was all based upon research conducted on healthy mice.

[Definition:  Microbiota - noun – the microorganisms of a particular site, habitat, or geological period.]

"We have shown for the first time in an established mouse model of anxiety and depression that bacteria play a crucial role in inducing this abnormal behaviour," said Premysl Bercik, senior author of the paper and an associate professor of medicine with McMaster's Michael G. DeGroote School of Medicine. "But it's not only bacteria, it's the altered bi-directional communication between the stressed host -- mice subjected to early life stress -- and its microbiota, that leads to anxiety and depression."

Within this study, the researchers subjected mice to early life stress with a procedure of maternal separation, meaning that from day three to 21, newborn mice were separated for three hours each day from their mothers and then put back with them.

Initially, Bercik and his team confirmed that conventional mice with complex microbiota. These mice also showed gut dysfunction based on the release of a major neurotransmitter, acetylcholine.
After that, they repeated the same experiment in germ-free conditions and found that in the absence of bacteria mice which were maternally separated still have altered stress hormone levels and gut dysfunction, but they behaved similar to the control mice, not showing any signs of anxiety or depression.
Subsequently, they found that when the maternally separated germ-free mice are colonized with bacteria from control mice, the bacterial composition and metabolic activity changed within several weeks, and the mice started exhibiting anxiety and depression.
"However, if we transfer the bacteria from stressed mice into non stressed germ-free mice, no abnormalities are observed. This suggests that in this model, both host and microbial factors are required for the development of anxiety and depression-like behaviour. Neonatal stress leads to increased stress reactivity and gut dysfunction that changes the gut microbiota which, in turn, alters brain function," said Bercik.

He said that with this new research, "We are starting to explain the complex mechanisms of interaction and dynamics between the gut microbiota and its host. Our data show that relatively minor changes in microbiota profiles or its metabolic activity induced by neonatal stress can have profound effects on host behaviour in adulthood."
Bercik said this is another step in understanding how microbiota can shape host behaviour, and that it may extend the original observations into the field of psychiatric disorders.

"It would be important to determine whether this also applies to humans. For instance, whether we can detect abnormal microbiota profiles or different microbial metabolic activity in patients with primary psychiatric disorders, like anxiety and depression," said Bercik.
