Alzheimer’s Drug Reverses Harmful Effects of Teenage Drinking in Rats

21 August 2019

An Alzheimer’s drug that is used to slow cognitive decline can reverse the brain damage caused by teenage drinking, shows a new rat-based study. Adolescent brains are more susceptible to alcohol damage than adult brains. Excessive teenage drinking reduces the formation of neurons in the hippocampus which impairs learning and memory. The damage can also […]

WHO Strips UK of Measles Free Status

The World Health Organisation (WHO) has stripped the United Kingdom of its measles free status following an increase in disease cases and falling vaccination rates. The UK recorded 913 cases of measles between 1 January and 31 October 2018, compared to 259 cases in 2017. This is despite measles being an entirely preventable disease. Measles […]

Sticky DNA Traps Cause Gallstone Formation

Sticky DNA traps produced by immune cells enable gallstones to stick together and grow, new research has revealed. Gallstones are stones that form in the gall bladder when the fats and minerals found in bile harden into a crystalline structure. Gallstones can cause inflammation and infections, depending on their size. Researchers investigated gallstones in patients […]

Digital DNA: Genetic Counselling – An Interview with Jill Davies

The Digital DNA series explores the role of large-scale genetic testing in science, industry and society. We aim to understand both the benefits and risks of this emerging technology and see what the future may hold. We talked to Jill Davies, CEO of GeneMatters. The company provides genetic counselling to patients through a telehealth platform […]

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 […]

New Drug Could Speed up Blood Cell Recovery after Chemotherapy

A drug that speeds up the regeneration of both mouse and human blood stem cells after radiation exposure could be used to successfully mitigate the side-effects of chemotherapy. Although radiation chemotherapy can be an effective cancer treatment, as it preferentially targets cancer cells over normal body cells, it can cause long lasting side-effects in patients. […]

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 […]

Cyber Organoids Let Scientists Observe Cell Development

Scientists have successfully grown a ‘cyber organoid,’ a simplified organ formed from stem cells with integrated electrochemical sensors to observe its development. Organs are formed by the self-assembly of stem cells into complex 3D structures. However, due to the difficulty of monitoring this process there are still significant gaps in scientists’ understanding. Electrochemical sensors have […]

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 […]

World Metastasis Summit 2019 Launch

When cancer cells break off from their initial tumour they can spread throughout the body and invade other organs to form new tumours, in a process known as metastasis. Metastatic tumours cause patients to develop stage IV or advanced cancer and are responsible for over 90% of deaths in cancer patients. In the past, cancer […]

New Blood Test Can Predict Cancer Progression

A new technique to analyse the tumour DNA present in patient’s blood circulations is an effective method to monitor breast cancer progression. The technique has been shown to give a hundred-fold improvement in the detection limit for tumour DNA. Analysis of the DNA that the tumour sheds into the bloodstream provides a non-invasive means of […]
