Genome Editing – The science behind ‘designer babies’.
A vote in the House of Commons last week has allowed the UK to become the first country to carry out mitochondrial DNA transfer in order to replace defective mitochondria in otherwise healthy women’s eggs. Arguments against this procedure included people believing that allowing the transfer of mitochondria would pave the way to the development of ‘designer babies’.
This may surprise some, but the…

Back to Basics: An Introduction to Viruses.
Stories about patients demanding antibiotics to treat cold and flu symptoms are all too common, highlighting the confusion many people have when it comes to understanding the difference between a viral and bacterial infection. It seems that a lot of people think viruses and bacteria are the same thing, and can therefore be treated with the same drugs. This post will give an introduction to…

Float like a jellyfish, sting like a bee
Float like a jellyfish, sting like a bee - a titbit of science behind bees, jellyfish and their venoms
It is common knowledge that to anger a bee is a bad idea as in situations of danger or in response to attack pheromones, the bee may sting you, injecting you with its venom, apitoxin. In the case of a jellyfish, stinging is a self-defence mechanism and is also employed in order to incapacitate prey. However, the mechanism by which they achieve this is much less well-known.
It is by the firing of…

Sneaky Chaperones in our War Against Bacterial Infection
Sneaky Chaperones in our War Against Bacterial Infection
I guess most of you know about the ‘central dogma’ of science of DNA-> RNA->Protein. But what happens next? You get a beautiful (in my opinion) folded functional protein that can do a mind-boggling array of things… and that’s not even the end of the story.
Proteins in our body do almost everything from allowing neural connections to repairing DNA to prevent cancers. These proteins although…

Amy Swanston:
Happy holidays everyone! We really enjoyed this festive post from et Al. so thought we would share it with you all. We’ve taken a little time off over this winter but will be back with your weekly dose of science in the new year!
Happy sciencing,
Amy.

Flu Season: Who's at Risk and Why
Flu season is upon us, and many people will be getting their yearly vaccine to protect them from this potentially lethal virus. The vaccine is offered to people at risk of flu, such as over 65s, pregnant women, and young children. So why have these groups been identified as being at risk of catching flu? And how effective is it at protecting them?
The elderly are at high risk of flu – a study of…

How the 5:2 Diet Reduces More Than Just Your Waistline
How the 5:2 Diet Reduces More Than Just Your Waistline
Intermittent fasting is the seemingly miraculous new weight loss method, popularised by the 5:2 diet followed by Benedict Cumberbatch, George Osborne, and Philip Schofield. Adherents to the 5:2 diet practise calorie restriction for two days a week (600 kcal for men and 500 kcal for women), and eat normally for five days a week. Intermittent fasting is an umbrella term that, along with the 5:2…

Research Focus: Prof. R Lewis, Newcastle University
Today we’re talking to Prof. Rick Lewis about his lab’s recent research article just published in Nature Communications, titled “Structure and function of a spectrin-like regulator of bacterial cytokinesis.” Rick is a specialist in structural biology, with his lab being based within Newcastle University’s Institute for Cell and Molecular Biology (ICaMB).

Experimental Techniques Explained; High Performance Liquid Chromatography
Experimental Techniques Explained; High Performance Liquid Chromatography
This week I’ve decided to focus on a scientific experimental technique used quite frequently nowadays, and one that can still be a bit of an enigma to rising students and sometimes just those not familiar with it. I’m talking about High-Performance Liquid Chromatography or HPLC (although it sounds like some kind of narcotic, don’t ask for a gram of HPLC from any strange men, kids… a gram is far…

The World Fights Back – Development of the Polio Vaccine
The World Fights Back – Development of the Polio Vaccine
Just over one hundred years ago, a man was born that would go on to develop a lifesaving vaccine that saved the lives of millions of children all over the world and although the disease is not eradicated completely, there are only around a thousand cases a year. The polio vaccine, developed by Jonas Salk, was the first ‘killed-vaccine’ where the virus is weakened and then injected and saved…

How Do You Like Your Eggs in the Morning? Frozen and Dipped in Liquid Nitrogen
If you’ve been watching the news or reading the paper recently, you’ll probably have heard about Apple and Facebook’s announcement that they will fund egg freezing procedures for their female employees; what you may not know is how this relatively unheard-of technique is carried out, how effective it is, or the reasons women opt to undergo such an expensive and novel procedure in order to delay…

The Controversy of the Birth of the Modern Cell
The Controversy of the Birth of the Modern Cell
In secondary school I remember being told wen being taught about the cell that the mitochondria, which has its own DNA and produces the energy that is required in the cell, was engulfed by a cell billions of years ago and that humans eventually evolved for that event to have mitochondria in each of our cells (except red blood cells). However due to a new study[1]from the university of Virginia we…

Ebola- Face The Fear
Ebola- Face The Fear
Ebola, the emerging threat from Africa, is without doubt a lethal killer. This serious threat has a grossly high mortality rate; the fatality rate for Ebola’s haemorrhagic fever (now known as Ebola Virus Disease, EVD) is roughly 50%, although it can be as high as 90%1.
Although it is currently headline news, Ebola has struck before on a smaller, but no less devastating, scale. Previous cases…

Evolutionary Theories of Obesity
Obesity is a growing problem in developed countries all over the world. In the UK alone, nearly 25% of adults (age 16 and over are obese) and it leads to other problems such as diabetes, heart disease and strokes. Humans haven’t always been obese and while we would like to blame the growing obesity crisis on our genes, it would be wrong to do so. Although our genes do play a part in our…

Biomarkers in Cancer Research: An Introduction
What are biomarkers and how are they used in cancer research? Find out here! #cancer #science
As a term, “Cancer Research” covers a broad range of scientific investigation. Many of us think of cancer research as the development of new drugs to treat patients – known as drug discovery research – but this is only a part of the field as a whole. Alongside drug discover and research into the fundamental biology of cancer, there is a huge area of research into biomarkers.
Biomarkers are often…

Run Towards The Light!: Characterising Near-Death Experiences
The term Near-Death Experience conjures up thoughts of walking down a long tunnel towards a bright light or floating above an operating table – easy to dismiss as a paranormal myth like a haunted house or an alien abduction. I was certainly sceptical about the existence of such experiences, until I read about scientific studies attempting to explain and characterise NDEs.
It turns out that it’s…
