America’s health data system is in crisis. The US government has been bleeding public health experts – many of whom run crucial public health surveys and databases which help identify, monitor and respond to health threats across the country. From drug use to food security and birth data, discover the 5 surveys most critically hit by the axing of over 20,000 jobs. If nothing is done to address this, vital health information will be missed and the results could be catastrophic.

Do you find it difficult to concentrate after a bad night’s sleep? This might be really common, but scientists are still trying to figure out why it happens. A new finding suggests it might have something to do with the brain’s “rinse cycle” – a process where your brain washes away metabolic waste and toxic proteins. Although this usually happens while you sleep, researchers have discovered it may continue in the day if you’re sleep deprived.

Life might exist on Mars right now, thanks to a network of liquid water on the Red Planet. Researchers examining Mars’ soil say there’s a good chance tiny veins of liquid water are hiding under the Martian permafrost and that they could support microbial life. This finding has scientists excited, with one suggesting “it’s not impossible that life could exist in the Martian near surface.”
