Now that the usually $13 train ticket has been hiked up to $105 for the World Cup, a lot of fans have been wondering whether it's possible to walk to MetLife Stadium from New York City.

To find out, we sent the intrepid Mark McPartland on a scenic hike to New Jersey to see if America’s pedestrian infrastructure is up to the task.

What he found was a challenging but occasionally scenic 4.5 hour walk that ended with blocked off pedestrian routes that would stop even the most adventurous European hiker from getting to the stadium during the World Cup

Cockrow Bridge in Surrey will open in the coming weeks to provide wildlife, including lizards and insects, with the ability to move between fragmented habitats

When James Herd moved near to Wisley Common 17 years ago, the heathland nature reserve was teeming with wildlife. “I’d take the dog around the common in spring and summer, and every few hundred metres I’d hear the rustle of a lizard in the undergrowth – and I’d see adders,” he says.

But over the past decade, the Surrey Wildlife Trust’s director of reserves management, who oversees the internationally important habitat, has seen that wildlife become depleted.

The transition towards renewable energy received a boost last week when representatives from 57 countries met in Santa Marta, Colombia, for a world-first climate meeting aimed at bringing the fossil fuels era to an end. Madeleine Finlay hears from the Guardian’s global environment editor, Jon Watts, about how the landmark conference came about, who was missing, and whether the optimism can translate into real world action

Could Santa Marta climate talks mark ground zero in push to ditch fossil fuels?

After a series of deaths on the beaches of Brittany, one bereaved family set out to prove the foul-smelling bloom was to blame

When her phone rang at around 5pm on 8 September 2016, Rosy Auffray was still at work. It was one of her daughters, distressed, calling to tell her that their father, Jean-René, had not come back from his daily run. Only the family dog had returned, alone and exhausted. Rosy rushed back home.

When she arrived, Rosy noticed that the dog was behaving bizarrely: she refused to walk, then collapsed under a bush. Her fur stank of rotten eggs, of overflowing sewers. Rosy knew where that smell came from: the mudflats roughly three miles from the family home in Brittany, where seaweed had been accumulating and putrefying. The soggy, decomposing seaweed stretched for miles along the shore, sometimes as much as five feet thick, killing other plants and suffocating fish and small birds.

Last month President Trump signed an executive order designed to fast track both research and access to psychedelic drugs as treatments for mental health illnesses. The most prominent in the order was ibogaine, a drug derived from the root bark of a West African shrub, that has shown some promise in relieving the long term effects of traumatic brain injury. Madeleine Finlay talks to journalist Mattha Busby about podcaster Joe Rogan’s role in the story, what else is behind the President’s interest in psychedelic research, and what the order will change in practice for scientists and researchers

Research from UCL suggests visiting art galleries or museums, singing and painting can help improve health outcomes

Singing, painting or visiting a gallery or museum helps people age more slowly, according to the latest study to link taking an active interest in art and culture with improved health.

The findings are the first to show that both participating in arts activities and attending events, such as viewing an exhibition, lead to people staying biologically younger.
