A fox in the sun, fireflies and a brush fire, and trees blanketed with butterflies are among the striking images caught by winners of the California Academy of Sciences’ annual contest. Now in its 11th year, it highlights biodiversity and the many threats our planet faces

Review says capital needs new reservoir, better flood defences and ‘heat plan’ for vulnerable people

Londoners who concrete over their gardens should be charged for doing so and given incentives to remove paving, a report to the mayor has recommended.

The city also needs a new reservoir, improved flood defences, and a “heat plan” to protect vulnerable residents from the increased risk of heatwaves, the report on the impact of the climate crisis has found.

Researchers from California Polytechnic State University have set up a webcam to observe a 'mega den' of as many as 2,000 rattlesnakes. Emily Taylor, the Cal Poly biology professor leading the Project RattleCam research, says the exact location in Colorado is being kept secret to keep snake lovers – or haters – away

Researchers say rattlesnakes have an undeservedly maligned reputation but are social creatures who make good mothers

A “mega den” with as many as 2,000 rattlesnakes isn’t top binge-watching for many people. But a round-the-clock webcam in Colorado is providing a viewing bonanza for scientists and other snake enthusiasts whose observations are helping to broaden understanding of these unusual – and undeservedly maligned – reptiles.

The remote site on private land in northern Colorado is on a hillside full of rock crevices where the snakes can keep warm and hide from predators.

Sustainable food experts want to revive fragile supply chains by using the games to ‘catalyse conservation’

Sustainable food advocates are calling for the amount of locally grown produce supplied to Brisbane to increase by 30% by the 2032 Brisbane Olympic Games to strengthen the city’s “fragile” supply chains.

But first, they have to figure out how much of Brisbane’s food is currently grown locally.

Company insists project should go ahead despite new government saying it had been unlawfully approved

The company behind the first new coalmine in the UK for 30 years has argued in the high court on Tuesday that it would be a “unique net zero” mine.

West Cumbria Mining (WCM) continued to defend the legality of its mine, which will produce 60m tonnes of coking coal in its lifetime, in the court days after the government said its planning permission was unlawful because it had not taken into account downstream emissions from using the coal.

Scientists believe the world’s rarest whale may have washed up on a New Zealand beach. Spade-toothed beaked whales have never been seen alive; beaked whales are believed to be exceptionally deep divers, spending their time far below the surface hunting squid and small fish. The specimen has been transported to cold storage and is awaiting examination. If confirmed to be a spade-toothed whale, it will be the first ever to be dissected by scientists.

As part of the annual Beaker Street festival, a celebration of science and art in Tasmania, finalist images in the festival’s annual science photographic competition will be on show at the Tasmanian Museum and Art Gallery from 6 August to 23 August

When I was in school, for a few weeks every year, caterpillars were the most exciting thing happening

• Get our weekend culture and lifestyle email

On the trunks of small magnolia trees, in the corner where a table leg meets a table top, on a low damp wall in the shade – here the hairy caterpillars gather together. They travel in long lines, they sleep as close to each other as possible (displaying, it is called in science, a high level of “gregariousness”), as though the scariest thing a predator might see is a cat’s disembodied tail or retched-up fur ball, or a too-small itchy blanket.

If you take a picture of a hairy caterpillar and put it on the internet, a stranger will tell you that you can safely touch it, while another will say you can’t under any circumstances. “What about that says, ‘Touch me’?” one person will ask. “People really need to get a grip,” another will write. “The caterpillars which are hazardous to touch are the hairy Marys, which have hollow hairs with venom. The hairy Marys are very obviously hairy.” This person sounds exactly like an older kid talking to a younger one.

The hikers were a father and daughter lost in Canyonlands and a woman who passed out at Snow Canyon state park

Three hikers died over the weekend in suspected heat-related cases at state and national parks in Utah, including a father and daughter who got lost on a strenuous hike in Canyonlands national park in triple-digit temperatures.

The daughter, 23, and her father, 52, sent a 911 text alerting dispatchers that they were lost and had run out of water while hiking the 8.1-mile (13km) Syncline Loop, described by the National Park Service as the most challenging trail in the Island in the Sky district of the south-east Utah park.

Melting of ice is slowing planet’s rotation and could disrupt internet traffic, financial transactions and GPS

The climate crisis is causing the length of each day to get longer, analysis shows, as the mass melting of polar ice reshapes the planet.

The phenomenon is a striking demonstration of how humanity’s actions are transforming the Earth, scientists said, rivalling natural processes that have existed for billions of years.

Rosamund Adoo-Kissi-Debrah is suing three government departments over Ella’s fatal asthma attack

The mother of a nine-year-old girl who became the first person in the UK to have air pollution cited on their death certificate has said she wants an official apology for her daughter’s suffering as her high court claim against the government heads to trial.

Rosamund Adoo-Kissi-Debrah is suing three government departments for compensation for personal injury arising from the illness and premature death of her daughter Ella, who had a fatal asthma attack in 2013 after being exposed to excessive air pollution.

Heat advisories are in place from Texas to New York as major east coast cities under air quality alerts

Millions of Americans are bracing themselves for dangerous temperatures at the start of the working week as a heat dome blankets the midwest and eastern United States.

Heat advisories are in place in Kansas and Texas all the way to New York and South Carolina, as the area of high pressure that caused misery in the west last week slowly makes its way across the country.

Tess, a 40-year-old female at Houston zoo, has been given a trial mRNA vaccine to help combat the virus, a leading killer of calves in captivity

An Asian elephant at Houston zoo in the US has received the first mRNA vaccine against herpes, which is the leading killer of Asian elephants calves in captivity.

Tess, a 40-year-old Asian elephant, was injected with the trial vaccine at the Texas zoo in June, after a spate of deaths in juveniles in zoos around the world from the elephant endotheliotropic herpesvirus (EEHV).

Senior climate figures welcome move after Conservative government largely left the role to junior ministers

Ed Miliband is to take personal control of the UK’s negotiations at vital international climate talks, in stark contrast to his Tory predecessors.

The energy security and net zero secretary will attend Cop29, this year’s UN climate summit, in Azerbaijan this November to head the UK’s delegation and meet political leaders from around the world.

Site in Pembrokeshire currently grazed by sheep will be planted with a range of species and reconnect to Celtic past

A lost piece of Celtic rainforest in the far south-west of Wales is to be restored to its ancient glory, weaving around standing stones and an abandoned, tumbling-down farmhouse with a waterwheel.

The 59-hectare (146-acre) site in Pembrokeshire will be planted with species such as oak, small-leaf lime and wild service (Sorbus torminalis) and should support an abundance of mosses, liverworts, lichens and ferns as well as providing a home for animals and other plant life.

It’s not entirely clear if fox numbers are on the rise in urban areas, but research shows they are learning to avoid hazards such as dogs and poisonous baits

Alex Abbey’s security camera captured something moving through an alley behind his home in Sydney’s eastern suburbs a few weeks ago. When he watched the 2am footage the next day, he was surprised to see a red fox on the screen.

“It’s unusual. It’s the first time I have seen one in Potts Point,” he says.

Over 245 million Americans are expected to experience 90F temperatures early this week, with some as high as 105F

A heatwave that impacted the US west coast over the past week is now moving east into the midwest and south-east, as millions of Americans have been under a heat alert at some point in the past week.

“Numerous near record-tying/breaking high temperatures are possible over the central High Plains and Southeast Sunday, and along much of the East Coast by Monday,” reported the National Weather Service.

Campaigners warn of same ‘tragic events’ as in River Wye if planners ignore pollution risks of intensive production

The chicken industry is facing calls to halt the expansion of intensive production in the River Severn catchment, with campaigners warning that the river is at risk from the same pollution that has blighted the River Wye.

An outcry over the ecological plight of the Wye has effectively halted the proliferation of intensive poultry units across the catchment. Campaigners say that the pollution threat is being transported “from one catchment to the other”.
