Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Lovelorn gerbils separated from their mates display the same symptoms as depressed divorcees, scientists have found. Researchers at Leeds University believe the rodents could provide useful models for studying the biochemistry of depression in humans.
The team discovered that gerbils, especially females, became withdrawn and suffered altered sleep patterns when they lost their lifelong partners. They became active when other gerbils were sleeping and slept when the others were active. Gerbils were "remarkably similar" to humans in that they formed lifelong partnerships, the lead researcher, Nicola Starkey, told New Scientist magazine.
By observing the chemical changes accompanying symptoms in separated gerbils it might be possible to identify new targets for human drugs.
