As a #scicommer, I often feel like we are talking in an echo chamber. 🎙️🔁 Preaching to the converted. Recycling the same ways of sharing science. 🧪 The main reason the reach is low isn’t a lack of information; it’s a lack of understanding of the scientific process itself! 🔍 1/5
Nearly 800 people joined @eara.eu 's webinar on the role of veterinarians in animal research.

It was a privilege to help frame a discussion that made visible an often unseen role, at the crossroads of animal welfare, ethics, regulation and scientific quality.

What happens when biodiversity drops? Disease-ridden mosquitoes turn to us. 🦟

This alarming study shows that as wildlife declines, mosquitoes increasingly feed on humans — raising the risk of diseases like dengue and yellow fever.

A clear reminder that ecosystem health is indeed public health.

What happens to viruses in spacewhen gravity disappears? 🦠 
Microgravity slows viral infection of bacteria , but pushed both onto new evolutionary paths.

Some of these changes may now help fight antibiotic-resistant infections on Earth.

Does reproduction make you live less?
This study suggests many mammals live longer when they don’t reproduce, especially females, likely because reproduction is so demanding on the body.

No simple lessons for humans here, but a reminder that health and reproduction are tightly linked in nature.

Depression treatment… at home?

The FDA has approved the first at-home brain stimulation device for depression — something that used to be limited to clinics.

The device, developed by Flow Neuroscience, stimulates brain regions responsible for mood and stress, which are often underactive in people with depression. www.eara.eu/post/first-a... #AnimalResearch

Ever wonder why starting an unpleasant task feels impossible? 😓

Researchers found a brain circuit in monkeys that acts like a “motivation brake” — it doesn’t kill the reward, it blocks the start.

A neat reminder that motivation isn’t about willpower alone, but how the brain handles discomfort 💪

Mammals regrowing their brain? 🧠🤯

Shrews can shrink their brains by ~20% in winter and grow them back later. No brain cells die, they just lose water and keep working.

A wild reminder of how flexible brains can be, and why nature still has a lot to teach us.

What if our brains don’t work the same without the “right” microbes? 🧠

This study suggests gut microbes alone can change brain-related gene activity, even across primate species throughout evolution, including humans.

Sometimes, the most interesting drivers sit outside the brain itself. 🤯

Why is relapse so common in opioid addiction?

This study found a specific brain pathway in rats that switches on during relapse drug-seeking behaviour.

When researchers reduced activity in that pathway using a light-basedmethod through brain implants, drug-seeking dropped clearly.

This debate is often reduced to slogans: Why are dogs used in research at all? 🐶

Dogs are rarely used in research, and only in specific, tightly regulated situations. What matters is why they are used, when, and how their use is reduced and only occurs when no other alternatives exist.
