New Technique to Select Offspring Gender

A reversible chemical technique can separate sperm carrying X chromosomes from sperm carrying Y chromosomes to select the offspring sex of mice. Cells from male mammals contain both an X and Y chromosome. However, sperm cells contain either an X or Y chromosome. As the female egg cell always contains an X chromosome, sperm that […]

Keto Diet Supresses Cancer Growth in Mice

Mice fed on a keto diet alongside an anti-diabetic drug were found to have slower progression rates of squamous cell carcinoma (SCC) lung tumours. The keto diet, currently widely popular, minimises sugar and carbohydrate intake. SCC is a type of cancer formed by the squamous cells that make up the epithelial layer of organs, including […]

Fish Can Conserve Memories Across Generations

The myth of the goldfish’s three second memory has long prevailed in popular culture. However, new research has suggested that unlike humans, fish are able to conserve memories over generations using epigenetic mechanisms. Epigenetic modifications can change the expression of DNA without changing the DNA code itself. Often this is in the form of DNA […]

Alternative Cause of Alzheimer’s Discovered

Alzheimer’s has previously been understood to be caused by a build up of protein plaques in the brain. However, new research has revealed that alternative metabolic pathways in the brain may be more integral to the formation of the disease. The plaques are formed by proteins known as beta-amyloid and tau. As Alzheimer’s progresses the […]

Genomics Medicine Ireland Announces Strategic Advisory Board

Genomics Medicine Ireland (GMI) has announced the establishment of a Strategic Advisory Board that will work collaboratively with GMI in shaping the company’s strategy for the application of large-scale genomics population studies on the island of Ireland, in addition to providing input and advice on the multi-disciplinary integration of genomics into the Irish healthcare system. […]

Genetic Mutation Significantly Increases Fruit Fly Lifespan

Fruit flies with a certain genetic mutation have significantly longer lifespans and better resistance to stresses than flies without the mutation. Fruit flies share a significant proportion of their genes with humans, making them good models to study human diseases and ageing. As the fruit flies usually live for about two months their lifespan is […]

Interview – Cath Stanley, CEO of the Huntington’s Disease Association

We talked to Cath Stanley, the CEO of the Huntington’s Disease Association. The charity offers support to those affected by Huntington’s, as well as carers and healthcare professionals, to ensure patients get the best care available. FLG: What is Huntington’s disease and What Are the Symptoms? CS: Huntington’s disease is a rare genetic disorder. It […]

Results of Melanoma Genetic Testing Motivate Positive Lifestyle Changes

Explaining to people that they have a high genetic risk for melanoma makes them choose positive lifestyle changes to reduce their risk, a new study has shown. Melanoma is a type of skin cancer to which certain people are predisposed to through genetic factors. These include having a family history of the disease and carrying […]

Genes that Allow Fish to Re-grow Limbs also Present in Humans

The genes that enable a fish to re-grow limbs have been found to be present in humans, new research has found. This insight could help develop regenerative treatments in humans. Many species can regenerate limbs after amputation including fish, salamanders and geckos. This can be used as a mechanism to escape predators and heal from […]

Cigarette Smoke Makes MRSA Superbug More Resistant to Antibiotics

Cigarette smoke has been found to make MRSA bacteria more resistant to antibiotics. The MRSA bacteria, s. aureus, can cause severe infections in humans. These are difficult to treat as MRSA is resistant to most commonly used antibiotics. MRSA poses a major problem in hospitals due to the high numbers of patients with open wounds […]

CRISPR Used to Find Genes that Protect Cells from Zika

A CRISPR technique has been used to identify genes in cells that enable them to survive infection of the Zika Virus. It is hoped that this development will lead to future treatments for Zika. Currently there is no vaccine or treatment specific to the Zika virus. If pregnant women contract the disease their unborn children […]

Chris Wigley Appointed CEO of Genomics England

Genomics England has today announced the appointment of Chris Wigley as Chief Executive Officer, with effect from 1 October. Chris joins Genomics England from QuantumBlack, a world leader in machine learning and artificial intelligence. Machine learning is critical in the analysis of the vast amounts of data involved in genomics, so Chris’ expertise in this […]

Being a Dog Lover is in Your Genes

Genetic factors contribute to how likely you are to own a dog, a new study has revealed. Evidence points to dogs being domesticated as early as 15,000 years ago. However, there is not much understanding to how this happened and if genetic factors had any influence. There is also debate if genetic influences could contribute […]
