How persistent bacteria 'sleep' through antibiotic attacks

19 February, 2021

Bacteria can survive antibiotic treatment even without antibiotic resistance by slowing down their metabolism and going into a type of deep sleep.

Small window of opportunity for recovery after stroke

18 February, 2021

The capacity of the human brain to recover and rewire itself peaks around two weeks after a stroke and diminishes over time, according to a new study.

Early signs of immune response found in developing embryos

17 February, 2021

Researchers found that epithelial cells — which collectively form the first tissue on the surface of an embryo — can recognise, ingest and destroy defective cells.

Neural roots of alcoholism identified

12 February, 2021

The physical origin of alcohol addiction has been located by researchers in a network of the human brain that regulates our response to danger.

Faecal transplant benefits cancer immunotherapy non-responders

09 February, 2021

Changing the gut microbiome can transform patients with advanced melanoma who never respond to immunotherapy into patients who do.

Disposition for risk-taking can be found in the brain

03 February, 2021

The genetic disposition for risk-taking is mapped in several areas of the brain, according to an international research team.

How certain gut bacteria compromise radiotherapy

29 January, 2021

Bacteria in the gut can dull the efficacy of radiotherapy, a treatment received by about half of all cancer patients.

Childhood neglect affects brain development over generations

21 January, 2021

Early life experiences can have an outsized effect on brain development and neurobiological health — an effect that can be passed down to subsequent generations.

Two-pronged approach to combat antibiotic resistance

07 January, 2021

The new compounds combine direct antibiotic killing of pan drug-resistant bacterial pathogens with a simultaneous rapid immune response for combatting antimicrobial resistance.

Protein's unexpected role in cancer cells

18 December, 2020

Researchers have made an unexpected discovery about the protein actin — one that will spark efforts to produce new tailored therapies to kill cancer cells.

Gut microbiota's role in brain function and mood regulation

17 December, 2020

French scientists have found that an imbalance in the gut bacterial community can cause a reduction in some metabolites, resulting in depressive-like behaviours.

Found: the missing link between stress and infertility

10 December, 2020

The RFRP neurons — a population of nerve cells near the base of the brain — become active in stressful situations and then suppress the reproductive system.

Specific gut bacteria linked to irritable bowel syndrome

03 December, 2020

Researchers have detected a connection between Brachyspira, a genus of bacteria in the intestines, and irritable bowel syndrome (IBS) — especially the form that causes diarrhoea.

Alzheimer's drug could help fight antibiotic resistance

24 November, 2020

An experimental Alzheimer's disease treatment is proving effective at treating some of the most persistent, life-threatening antibiotic-resistant bacteria.

Children use both brain hemispheres to understand language

30 October, 2020

Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain's two hemispheres, infants and young children use both.
