Plants found to carry bacteria in their cells

11 May, 2021

Scientists have described how healthy plants appear to carry bacteria in their cells, opening a new avenue of research to improve future plant health and propagation efforts.

How immune cells communicate across the blood–brain barrier

06 May, 2021

Scientists have developed a high-tech laser microscopy imaging model, which has given them a rare peek inside blood vessels to watch immune cell behaviour in real time.

Stress can literally stop immune cells in their tracks

30 April, 2021

Signals 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, 2021

Darobactin, 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, 2021

The 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, 2021

Increased 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, 2021

Scientists 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, 2021

Anabolic 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, 2021

Infants 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, 2021

Researchers 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, 2021

A 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, 2021

Tumours 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, 2021

The 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, 2021

Scientists 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, 2021

Using 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.
