Stress can literally stop immune cells in their tracks
30 April, 2021Signals produced by nerves in response to stress can stop immune cells from moving, and thus from effectively fighting pathogens or tumours.
Novel antibiotic tricks bacteria through mimicry
29 April, 2021Darobactin, a newly discovered antibiotic compound, kills many antibiotic-resistant pathogens by exploiting a tiny weak spot on their surface.
Light-activated molecule clears Alzheimer's protein in mice
26 April, 2021The small molecule is known as a photo-oxygenation catalyst, and appears to treat Alzheimer's disease via a two-step process.
The brain region that can predict stress resilience
21 April, 2021Increased sensitivity in a specific region of the brain contributes to the development of anxiety and depression in response to real-life stress.
Researchers create human–monkey chimeric embryos
20 April, 2021Scientists have injected human stem cells into primate embryos and were able to grow chimeric embryos for up to 19 days.
Steroids accelerate brain ageing
12 April, 2021Anabolic androgenic steroids (AAS), a synthetic version of testosterone, can have deleterious effects on the brain, causing it to age prematurely.
Gut microbiota in caesarean-born babies catches up
08 April, 2021Infants born by caesarean section have a relatively meagre array of bacteria in the gut, but by the age of three to five years they are broadly in line with their peers.
Experimental HIV vaccine trialled in humans
05 April, 2021Researchers from IAVI and Scripps Research have developed a novel vaccine approach to prevent HIV which has produced promising results in a phase 1 clinical trial.
Hypnosis changes how the brain processes information
01 April, 2021A new study shows that the brain may function quite differently during hypnosis when compared to a normal waking state.
Tumours can be stripped of their T cell protection
24 March, 2021Tumours use a unique mechanism to switch on regulatory T cells to protect themselves from attack by the immune system — so what would happen if these T cells were shut down?
Early human embryo models generated from skin cells
22 March, 2021The breakthrough is expected to revolutionise research into the causes of early miscarriage, infertility and the study of early human development.
Gut bacteria prompt mother mice to neglect their pups
18 March, 2021Scientists have identified a strain of E. coli bacteria that, when living in the guts of female mice, causes them to neglect their offspring.
Viruses used as 'vehicles' to deliver cancer vaccines
10 March, 2021Using two different viruses as vehicles, researchers administered specific tumour components into mice with cancer in order to stimulate their immune system to attack the tumour.
New bone cell could reveal targets for osteoporosis treatment
05 March, 2021A research team has discovered a new type of bone cell that may reveal new therapeutic approaches for osteoporosis and other skeletal diseases.
How persistent bacteria 'sleep' through antibiotic attacks
19 February, 2021Bacteria can survive antibiotic treatment even without antibiotic resistance by slowing down their metabolism and going into a type of deep sleep.
