The Venice Film Festival has opened with Noah Baumbach's latest, which stars Adam Driver as a bumbling college professor-turned-action hero. It could be his best role yet, writes Nicholas Barber.

Scientists suspect someone polluted the water with a substance that appears to have caused high salt levels. That encouraged golden algae to flourish. The toxins it emitted killed the fish. The rotting corpses then further reduced the water quality.

A deadly, chemical chain reaction which, they say, may have been exacerbated by a hot summer and low river levels. But they have yet to identify the original pollutant.

"It will be difficult to get a clear answer to what caused it," says Andrzej Kapusta, of the Inland Fisheries Institute. We joined him and his team on board a small boat as they tested the water in the Oder.

Two people who sparked a concerned call to mountain rescuers were actually sowing rare plants.

A walker was descending Swirral Edge on Thursday when he saw the pair and a dog high up on Helvellyn headwall, Patterdale Mountain Rescue Team said.

Two rescuers went to investigate when the walker reported the pair were not moving and feared they were stranded.

They discovered they were from the John Muir Trust and planting rare arctic-alpine plants.

The team said the two people and a dog were on a steep area with no footpaths and accessible usually only by climbers.

Reacting to the happy outcome it said: "We like a good ending."

"The John Muir Trust do great work looking after the Glenridding Common, re-establishing rare plants and mountain woodland species as well as loads of other conservation work," it said.

A weaker or unstable jet stream can result in unusually hot air coming to Europe from North Africa, leading to prolonged periods of heat. The reverse is also true, when a polar vortex of cold air from the Arctic can cause freezing conditions far south of where it would normally reach.

Hoffmann said observations in recent years have all been at the upper end of what the existing climate models predicted.

The drought has caused some European countries to impose restrictions on water usage, and shipping is endangered on the Rhine and the Danube.

The Rhine could reach critical low levels in the coming days, making the transport of goods — including coal and gasoline — increasingly difficult. On the Danube, authorities in Serbia have started dredging sand to deepen the waterway and keep vessels moving smoothly.

A SpaceX Falcon 9 rocket thundered into space Thursday evening and sent a South Korean science probe on its way to the moon for an ambitious mission to help look for ice deposits in permanently shadowed polar craters.

Equipped with four Korean instruments – two cameras, a gamma ray spectrometer and a magnetometer – the Korean Pathfinder Lunar Orbiter (KPLO) spacecraft also features an ultra-sensitive NASA camera known as "ShadowCam" that's designed to peer into those dark craters to help scientists see what's actually there.

If ice has, in fact, accumulated in the icy shadows, and if it's accessible, future astronauts might be able to break it down into hydrogen and oxygen. Ice would provide air, water and even rocket fuel, assuming the infrastructure to extract it is feasible with affordable technology.

Keen to gather similar data for Britain, the Scottish Meteorological Society decided to build a weather station at the top of Ben Nevis. For a trial run, one particularly intrepid member scaled the mountain every day for four months – through blizzards, gales, and heavy storms – to record measurements at the summit. Funding to build the station and obtain the instruments was raised through a kind of 19th-Century crowdfunding initiative. Even Queen Victoria donated.

And so began a remarkable experiment in Victorian stoicism and scientific endeavour. From 1883 to 1904, a few hardy individuals lived year-round in a small stone hut, surviving on tinned food and making hourly recordings of everything from atmospheric temperature to humidity, wind speed to rainfall. In total they made almost 1.5 million observations – often going to extraordinary lengths and risking their lives to record data in the most hostile of conditions.

Underwater mining for fuels like oil and gas can also produce bursts of ocean noise. Sometimes, excavation teams set off large explosions, or use seismic air guns in sharp bursts from a ship above to push through the ocean floor.

Hildebrand argues that restrictions are needed for such noise exposure of marine animals, "in much the same way that OSHA [the US Occupational Safety and Health Administration] limits human exposure to high levels of noise". Restrictions could include decibel limitations at certain points in bodies of water where vulnerable marine habitats exist, regulated by environmental government agencies like the Environmental Protection Agency (EPA) in the US.

These agencies could also provide guides for different industries to reduce their sound emissions. Seismic survey noise, for example, can be tempered by releasing the air in more continuous, lower frequency pushes over longer periods of time – a process called marine vibroseis.

An alarming 81% of traditional apple orchards have vanished from Britain, but activists are planting British heritage varieties in community plots in all shapes and sizes.

Tom Adams is a detective. But he doesn't track criminals – his targets are "lost" apple varieties hiding unsuspected in orchards around the UK, and his work taps into a renewed British passion for its rich larder of heritage apples.

While you'd be lucky to find half a dozen apple varieties in any supermarket (some of those imported), there are currently around 2,200 species of apple recorded in Britain's National Fruit Collection at Brogdale Farm in Kent, with new discoveries being made by apple hunters around the country.

Adams' apple-detecting beat focuses on The Marches, an ancient heartland of British apple growing that takes a bite out of the counties of Shropshire and Herefordshire where England merges into Wales. It was here, in a neglected orchard, that a single tree bearing mysterious bright yellow apples stirred his curiosity. No one knew when it was planted and neither Adams' expert eye nor archival records could quickly identify the variety.

The disappearance of giant sequoia genetics is also a concern. "We don't know what we may have lost," said Brigham. "But we are talking about a species that has already gone through a genetic bottleneck and is only found in 78 groves. Now we have these wildfires that have burned up 19% of the adult large-tree population. In one grove, 80% of the grove is gone."

Milarch's organisation, now called Archangel Ancient Tree Archive, is still cloning trees, and they are now heading to California to search for, and hopefully clone, a "lost" grove of sequoias that Milarch believes may set a new record for size.

They are also planting old growth groves. "We planted 75 redwoods cloned from old growth trees at the Presdio," he told me recently, referring to a former army base that has since become a park. "And we've planted sequoias in 41 cities in the Puget Sound area as part of assisted migration."

A little-known meteorological phenomenon makes a tiny village in Arctic Sweden one of the best places on Earth to consistently see the Aurora Borealis.
"I'm not so sure we'll see them," said my videographer colleague Erik Jaråker, as he looked at the fog all around. I was driving us up the single-lane highway towards one of Sweden's northernmost villages, Abisko, located 250km north of the Arctic Circle. We were caught in the middle of a snowstorm with zero visibility, and all around us, the mountains of Abisko National Park had become a sea of white.

We were heading up to photograph the elusive Northern Lights – nature's spectacular light show, also known as the Aurora Borealis. The displays occur when explosions on the sun's surface, called solar flares, collide with gases in the Earth's atmosphere to create shimmering bands of red, green and purple. To witness this Aurora activity, we needed frigid, clear, cloudless skies, not the winter storm we were currently slogging through.

"Trust me," I assured him confidently. "We'll see them."

I'd been here before under similar storm conditions, and I'd quickly learned that Abisko is home to a "blue hole", a patch of sky that extends 10 to 20 sq km over the village, Lake Torneträsk and Abisko National Park and that remains clear regardless of surrounding weather patterns. This phenomenon makes Abisko one of the best places in the world to consistently witness the Aurora Borealis.

When ‘potential’ is seen as crucial to moving up the career ladder, women seem to lose out. Why?

In her 2013 book Lean In, Facebook COO Sheryl Sandberg claimed that most men would apply for positions when they met just 60% of the requirements, while women would only apply if they met 100% of them. Sandberg’s claim was later debunked, due to its basis on anecdotal evidence rather than hard data – yet the sketchy statistic just wouldn’t go away.

It’s since been quoted in dozens of viral posts, articles and books, and is regularly used to prove that men’s potential is somehow more valued than women’s. Something about the idea resonated so deeply with people that its lack of factual backing didn’t seem to matter – it spoke to a phenomenon people were seeing and experiencing in their own lives.

Now, emerging research points to why the idea that women’s potential is judged differently to men’s rang true for so many women. A new study has shown women are consistently judged as having less leadership potential than their male counterparts, making them 14% less likely to be promoted each year. The research, which looked at a large North American retail chain, showed that even though women scored better performance ratings, they tended to receive low ‘potential scores’ – a measure of how much their managers believed that they would grow and develop in future.

Deciding whom to promote can be complicated business. Candidates have to demonstrate strong skills at their current level, and their managers also must believe they have the ability to perform at the next level up. Yet potential isn’t easily demonstrated; subjective measurements that assess it open the door for bias – and women often suffer as a result.

Some argue that hiring managers are solely at fault, with their inherent biases making it difficult to imagine women as leaders; others claim women are also holding themselves back by failing to self-promote. But the proof-versus-potential problem doesn’t just show up in the workplace – and solving such a deeply ingrained issue is far from straightforward.

The thriving port town of Dunwich was lost to storms in the 13th Century. But scientists recently have discovered that it wasn't lost at all – it's simply underwater.

Midway between the town of Aldeburgh and the seaside resort of Southwold, two popular spots on Britain's Suffolk coast, lies the quiet rural village of Dunwich. Around 200 people live in this one-road settlement with its cosy pub/B&B, local museum, long gravel beach and monastery ruins.

You wouldn't know it now, but in the Middle Ages the village was a thriving port the size of the City of London's square mile, built on fishing, trade and religious patronage. Greyfriars Monastery was established by Franciscan monks in the 1250s on lower-lying ground closer to the sea.

But a massive storm in 1286 swept away the monastery, along with many homes and other buildings. The crumbling stone walls you can visit today are the remains of the "new" friary, rebuilt in the late 13th Century on land half a mile from the sea. They now stand perilously close to the edge of the cliffs – illustrating how storms, surges and coastal erosion turned the tide on thriving Dunwich, some of which was later built on higher ground.
