Stress influences the brain via the immune system

16 February, 2024

Stress increases the migration of white blood cells called monocytes into the vascular system of the brain, particularly into the reward centre regions.


Love scrambles the brain — and scientists can tell us why

14 February, 2024

The way that our loved ones take on special importance is due to oxytocin combining with dopamine, a chemical that our brain releases during romantic love.


How aging alters brain cells' ability to maintain memory

09 February, 2024

While it is well established that memory can worsen as people age, it has not been clear what changes occur at the individual brain neuron level to cause this.


'Mini placentas' help us better understand pregnancy disorders

07 February, 2024

Scientists grew 'mini placentas' in the lab and used them to shed light on how the placenta develops and interacts with the inner lining of the womb.


Placenta cells may lower blood pressure, study finds

06 February, 2024

While a drug can reduce high blood pressure, these cells could target inflammation in the arteries caused by hypertension.


Cell-based flu vaccine joins National Immunisation Program

05 February, 2024

Cell-based flu vaccines are designed to be a close match to the strains selected by the WHO as likely to be prevalent for the upcoming flu season.


Dopamine release explains why exercise boosts your brain

30 January, 2024

We know cardiovascular exercise improves cognitive performance, but the mechanisms behind this process have not been rigorously investigated in humans until now.


Amnesia caused by head injury reversed in mouse study

25 January, 2024

Amnesia and poor memory following head injury is due to inadequate reactivation of neurons involved in forming memories — and has the potential to be reversed.


Humidity and temperature affect foetuses' future blood pressure

22 January, 2024

Outdoor humidity and temperature levels during pregnancy appear to affect the future blood pressure of the unborn child, according to an international study.


Disrupted sleep in midlife tied to cognition problems later on

15 January, 2024

People who have more disrupted sleep in their 30s and 40s may be more likely to have memory and thinking problems a decade later.


Lost brain function can be restored after stroke

11 December, 2023

Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules, which could in future be developed into a stroke recovery therapy.


Placebos could help to treat depression and ADHD

05 December, 2023

Taking into account whether people believe they are receiving a real treatment or a placebo could help improve interventions for conditions such as depression and ADHD.


Exercise boosts cognitive function after a bad night's sleep

04 December, 2023

Moderate-intensity exercise can improve cognitive function in people who are sleep deprived and have low levels of oxygen, researchers have found.


Nanoscale probes reveal how cell structure responds to pressure

27 November, 2023

By giving living cells a 'poke' and monitoring the results, scientists have gotten their first glimpse of how whole cells respond to external mechanical pressure.


Maternal gut bacteria found to communicate with foetus

17 November, 2023

In healthy pregnancy, nanoparticles secreted by maternal gut bacteria migrate to the amniotic fluid, containing molecules derived from bacteria.
