Higher rates of mutation alone are not to blame for age-related disease
Small mutations accumulating in DNA are unlikely to be fully responsible for the ageing process, finds a new study carried out in collaboration with the University of Birmingham. The research into the theories of ageing found that human cells and tissues can accumulate many more mutations than are normally present, without the body showing the features associated with ageing.

Genetic risks for depression differ between East Asian and European groups
Specific genes increase the risk of developing depression, according to a new study led by UCL researchers, which also shows that the genes associated with depression vary depending on ancestry group. The research, published in JAMA Psychiatry , is the largest study into the genetic risks of depression conducted in non-European populations.

Magnetic stimulation of the brain can improve episodic memory
Inhibitory brain stimulation allows better memorization by reducing the power of beta-waves in the brain. Memories of past events and experiences are what define us as who we are, and yet the ability to form these episodic memories declines with age, certain dementias, and brain injury.

Our eyes and brain work together to create a ’pipeline’ of meaning - new study
Humans read by 'pre-processing' written words to create a pipeline of meaning, according to new research at the University of Birmingham. A study, published in Nature Communications , shows that each pre-processing judgement can take place extremely rapidly - within just 100ms after the eye lands on the previous word.

Primate mothers may carry infants after death as a way of grieving
Some primate species may express grief over the death of their infant by carrying the corpse with them, sometimes for months, according to a new UCL-led study - with implications for our understanding of how non-human animals experience emotion. Published today in Proceedings of the Royal Society B , the researchers compiled data from anecdotes reported in 126 publications on primate behaviour.

Opinion: Multiple sclerosis linked to infection in adolescence - new study
Infections of the central nervous system and respiratory system in youth have been found to increase the risk of MS significantly, says Professor Scott Montgomery (UCL Institute of Epidemiology & Health). Multiple sclerosis (MS) is most often diagnosed between the ages of 20 and 50. Certain genes put a person at greater risk of getting this disease of the central nervous system, but scientists are still trying to understand the triggers.

Researchers get to the heart of fish health with new diagnostic tool
A group of aquaculture researchers in Scotland is aiming to develop a simple and cost-effective mass testing tool that could significantly enhance fish health and wellbeing, by quickly and proactively detecting and differentiating between a range of cardiac conditions in salmon. The consortium will seek to better screen and characterise the heart health of salmon by studying specific blood biomarkers that indicate the presence of cardiomyopathies such as heart and skeletal muscle inflammation (HSMI), cardiomyopathy syndrome (CMS), and pancreas disease (PD).

Plants evolved ability to actively control water-loss earlier than previously thought
New research has shed light on when plants first evolved the ability to respond to changing humidity in the air around them, and was probably a feature of a common ancestor of both flowering plants and ferns. Key to the regulation mechanism are tiny holes, or pores, on the surface of leaves, called stomata.

Researchers identify genetic cause of endometriosis and potential drug target
Endometriosis is a painful, chronic condition in which tissue from the uterus inappropriately grows outside the uterus. Current treatments are limited and include surgery and hormone therapy, which can involve unwanted side effects. New research conducted by the University of Oxford, Baylor College of Medicine, the University of Wisconsin-Madison and Bayer AG, offers new insight into how to treat this debilitating disease.

Farmed carnivores may become 'disease reservoirs' posing human health risk
Farmed carnivores may become ’disease reservoirs’ posing human health risk
Carnivorous animals lack key genes needed to detect and respond to infection by pathogens, a study has found. We've found that a whole cohort of inflammatory genes is missing in carnivores Clare Bryant Farming large numbers of carnivores, like mink, could allow the formation of undetected 'disease reservoirs', in which a pathogen could spread to many animals and mutate to become a risk to human health.

’Vegetarian’ giant tortoise filmed attacking and eating seabird
Researchers have captured on film the moment when a Seychelles giant tortoise, Aldabrachelys gigantea , attacked and ate a tern chick. This is the first documentation of deliberate hunting in any wild tortoise species. The whole interaction took seven minutes and was quite horrifying Justin Gerlach The hunting tortoise was seen in July 2020 on Frégate Island, a privately owned island in the Seychelles group managed for ecotourism, where around 3,000 tortoises live.
