This is figure 1, which shows global and regional PM2.5 pollution from the 2023 Canadian wildfires.

Around 354 million people in North America and Europe are likely to have been affected by fine particulate matter pollution from the 2023 Canadian wildfire season, a paper published in Nature suggests. go.nature.com/42iffKC ⚒️ 🧪

Heat extremes attributable to climate change have led to a 25–38% average reduction in monitored tropical bird populations since 1950, according to a study in Nature Ecology & Evolution. go.nature.com/3UIIpP7 🧪

Nature is awesome

The brain fires up immune cells when sick people are nearby When people viewed virtual avatars with coughs or rashes, their brains triggered an immune response.

The brain activates front-line immune cells in response to the mere sight of a sick person

First plenary session of #AAIC25 a great start!

If you want to know a little bit more about my work relating brain cell densities and Amyloid burden go to Poster 057 today at AIC! #AAIC25 #AIC

It will be awesome!

✈️ Toronto, here we go! The ZLAB team is heading to #AAIC2025, the world’s largest conference on AD and dementia. 5 days of science, learning and a chance to showcase research made in Brazil🧠

Symbolic ‘science fair’ showcases research cut by Trump team Democrats hosted a protest event featuring ‘things we’ll never know’ because of the US government’s cuts to science.

A few dozen scientists protested the cancelling of their research grants by the Trump administration at a ‘science fair’ staged yesterday in Washington DC.

Awesome text

Kinda beautiful

Congratulations to Science Magazine to this awesome cover

Ok, this is particularly concerning

Your brain is full of microplastics: are they harming you? Plastics have infiltrated every recess of the planet, including your lungs, kidneys and other sensitive organs. Scientists are scrambling to understand their effects on health.

Microplastics have been found just about everywhere scientists have looked. Now scientists are trying to determine their effects on your health

This animal is awesome, incredible vision, strength, and exoskeleton structure! Small animal with a great features ☺️

Social and health disparities associated with healthy brain ageing in Brazil and in other Latin American countries Our findings indicate that Brazil converges with other Latin American countries to show that heterogeneous factors impacted more than demographic factors, but also showed a unique set of health factor...

New Study just out in The Lancet Global Health! #LucasDaRos, @vbwyll.bsky.social, #CristianoAguzzoli & colleagues used a machine learning model to determine the most important risk factors for cognitive and functional decline in Brazil and other LATAM Countries 🧵 www.thelancet.com/journals/lan...

This is figure 1, which shows weighted means for trust in scientists across countries and regions (1 = very low, 3 = neither high nor low, 5 = very high).

What is the state of trust in scientists around the world? A study in Nature Human Behaviour reports on a survey of 71,922 respondents in 68 countries and finds that trust in scientists is moderately high. https://go.nature.com/3PLgKKU 🧪

Oligodendrocytes produce amyloid-β and contribute to plaque formation alongside neurons in Alzheimer’s disease model mice - Nature Neuroscience In Alzheimer’s disease, neurons are considered the sole source of amyloid-β (Aβ) peptides that form plaques. Here the authors show that oligodendrocytes, the myelinating glial cells of the brain, also...

It's time to share a high level of science. I love this paper; when it was published, my reaction was 😱. Because I always ask, why do we look at the same cells all the time? Why do we call them 'neurons & glia'? Why weren’t the brain cells classified in the same way?

Great work!

Why is so difficult to make new scientific connections on this app? The algorithm appear to don't works well

Let's start to use bluesky!
