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.

Male brains are wired to choose sex over food, new scientific research suggests.

Researchers observing a species of microscopic roundworms called C.elegans found that male worms given the choice between looking for food and finding a mate tended to choose the latter.

The same findings were not present in the hermaphrodite organisms studied – the species has no female sex.

Some of the male worms observed were genetically engineered to be more sensitive to food. Researchers found that these ‘hungrier’ worms were ten times less successful at mating as they wanted to stay near the source of food.

The authors of the study say they believe male worms were more able to suppress their hunger in order to go out and find a mate.

Assistant Professor Douglas Portman from the University of Rochester, who was involving in conducting the study, said the findings shed new light on genetic difference between sexes.

“These findings show that by tuning the properties of a single cell, we can change behaviour,” he said.

“This adds to a growing body of evidence that sex-specific regulation of gene expression may play an important role in neural plasticity and, consequently, influence differences in behaviours - and in disease susceptibility - between the sexes.“

Although the study did not involve humans, many previous discoveries made by observing C. elegans apply throughout other animals.

Scientific findings based on the species behaviour are generally thought to be particularly applicable in neuroscience.

The study was published in the scientific journal Current Biology.
