Immune cells in older adults fall short in virus detection
18 October, 2023Killer T cells in older adults, directed against influenza viruses, closely resemble those found in newborns and children, but struggle to recognise infected cells.
Survivors of cardiac arrest recall experience of death
16 October, 2023Some cardiac arrest patients revived by CPR had clear memories of experiencing death and even had brain patterns that were linked to thought and memory while unconscious.
Immune cell discovery sparks hope for bowel cancer patients
13 October, 2023Researchers have discovered that an important group of immune cells in the large bowel — gamma delta T cells — is crucial to preventing bowel cancer.
Inflammation-causing gene carried by millions
11 October, 2023A genetic change that increases the risk of inflammation, through a process described as 'explosive' cell death, is carried by up to 3% of the global population.
Brain chemical makes alcohol taste more bitter to women
05 October, 2023Scientists have identified a chemical in the brain that makes alcohol taste bitter to females, unless the drink is sweetened.
Immune cells move more independently than we thought
03 October, 2023Immune cells do not just passively follow chemical cues in order to reach their target. In fact, they are capable of navigating complex environments in a self-organised manner.
Bacteria can cause — or prevent — wheezing in young children
02 October, 2023Combinations of bacteria found in dust at day care facilities have been linked to wheezing in young children — but those with more mature gut microbiota are less likely to develop the condition.
Disrupted link between memory and appetite explains obesity
27 September, 2023Individuals who are obese have impaired connections between the dorsolateral hippocampus (dlHPC) and the lateral hypothalamus (LH).
T cells in the brain slow progression of Alzheimer's
20 September, 2023Scientists have found that a subset of CD8+ T cells in the brain lessens the activation of microglia and limits disease pathology in a model of Alzheimer's disease.
Genetic evidence shows that smoking causes us to age faster
13 September, 2023A study of nearly 500,000 people has shown that smoking shortens the end fragments of chromosomes in the white blood cells of our immune systems.
Brain protein deficiency promotes compulsive behaviour
12 September, 2023The absence of two proteins in mice, Intersectin1 and Intersectin2, leads to disrupted neural signalling and compulsive repetitive behaviour.
Reduced grey matter in frontal lobes linked to teenage smoking
06 September, 2023Levels of grey matter in two parts of the brain may be linked to a desire to start smoking during adolescence and the strengthening of nicotine addiction.
Inflammation slows malaria parasite growth in the body
04 September, 2023Inflammation in the body can slow down the development of malaria parasites in the bloodstream, which may prevent or limit severe disease.
RSV vaccine remains effective against distinct viral variants
28 August, 2023 by Lauren DavisGSK's Arexvy vaccine for RSV can remain effective against a range of variants and produces strong antibody responses against distinct viral strains.
New antibiotic sourced from 'microbial dark matter'
25 August, 2023A powerful new antibiotic, isolated from bacteria that could not be studied before, seems capable of combating harmful bacteria and even multi-resistant 'superbugs'.
