The kākāpō has had its most successful breeding season since conservation efforts rescued it from the brink of extinction in the 1970s

The world’s heaviest parrot, a critically endangered bird that only lives in a remote part of New Zealand, has had its most successful breeding season since conservation efforts began more than two decades ago.

Thirty-seven kākāpō chicks are currently surviving, providing a much-needed boost to the population of 123 adult kākāpō which live on predator-free islands.

Corals on Loomis Reef are dying as one veteran scientist lets the “veil” of academia drop to reveal anger and frustration

Stretching for half a kilometre or so, Loomis Reef is the place where the alarm bells started going off.

Prof Justin Marshall has been diving this reef, about 270km north of Cairns, for 30 years. Right now he is, to say the least, angry.

PANAMA MONKEY: The discovery of seven little fossilised teeth during excavations to expand the Panama Canal provides the first evidence of a monkey on the North American continent.

AGEING BRAIN: People often find it harder to adapt to new situations as they age and now a new mouse study may have shed light on why.

Animals and plants are increasingly being ‘translocated’ from their native areas to survive effects of climate change, poaching and habitat loss, says top conservationist

More than 1,000 species have had to be relocated because of climate change, poaching and humans taking their habitat, according to a top conservationist.

Dr Axel Moehrenschlager said cases of “translocation”, such as India’s plan to relocate tigers to Cambodia or South Africa’s scheme to airlift rhinos to Australia, have increased exponentially in recent decades and will become more common due to human pressures driving species closer to extinction.

Oil giant warned industry would pull out of EU if laws to cut pollution and speed clean energy take up were passed, letter obtained by the Guardian reveals

The EU abandoned or weakened key proposals for new environmental protections after receiving a letter from a top BP executive which warned of an exodus of the oil industry from Europe if the proposals went ahead.

In the 10-page letter, the company predicted in 2013 that a mass industry flight would result if laws to regulate tar sands, cut power plant pollution and accelerate the uptake of renewable energy were passed, because of the extra costs and red tape they allegedly entailed.

American Lung Association’s ‘state of the air’ report finds 166 million Americans are living in unhealthy ozone or particle pollution with serious health risks

More than half of the US population lives amid potentially dangerous air pollution, with national efforts to improve air quality at risk of being reversed, a new report has warned.

A total of 166 million Americans live in areas that have unhealthy levels of either ozone or particle pollution, according to the American Lung Association, raising their risk of lung cancer, asthma attacks, heart disease, reproductive problems and other ailments.

Maxima Acuña de Chaupe has won a major environmental prize for defending her land from the biggest gold-mining project in South America

Environmental activism may not have been what Maxima Acuña de Chaupe had in mind when in 2011 she refused to sell her 60-acre plot of land to the biggest gold-mining project in South America.

She did not belong to any movement or organisation but she doggedly held on to her land in spite of her claims of beatings, death threats, intimidation and court proceedings, becoming a symbol of resistance in her native Peru and above all its northern region of Cajamarca which rejected the $4.8bn Conga gold mine after five demonstrators were killed in clashes with the police in 2012.

Relaxing of specifications on fine green beans is expected to save more than 135 tonnes of edible crops being wasted each year, supermarket says

Tesco is to relax rules on fine green beans imported from Kenya in a move expected to save more than 135 tonnes of edible crops from going to waste every year.

The UK’s largest retailer said shoppers’ preoccupation with pre-prepared vegetables had meant that until recently growers were required to supply fine beans within a strictly specified size range, and then trim them of their “strings” before being packed and shipped to the UK.

The tiny beads used in exfoliant scrubs and toothpastes are at various stages of being phased out by the industry. Until a blanket ban comes into force, here’s a handy list of popular brands to help you choose which to use and which to avoid

Last week, Greenpeace found that two-thirds of the British public it polled think plastic microbeads used in exfoliant toiletries should be banned.

The tiny beads - found in face and body scrubs and some toothpastes - are too small to be captured through existing wastewater treatment processes, and wash straight into the ocean where they harm fish and other sea life.

SLEEP DEPRIVATION: Women's ability to perform tasks accurately is reduced when working night shifts into the early morning, according to a new study that details for the first time differences between men and women's sleep-wake cycles and circadian rhythms.

The city of Miami Beach is slowly disappearing under water. At the big high tides of the year the sea washes over the famous wide beach and floods many of the city streets and magnificent Art Deco buildings. And over the past decade the floods have been striking more frequently.

Most of the city sits just a few feet above sea level, built on a foundation of porous limestone, allowing the rising seas to seep into the city’s foundations, surge up through pipes and drains, encroaching on fresh water supplies and saturating infrastructure. The city is now investing in a $500m project to raise roads and a pumping system to hold back the floods.

Cambridge physicist and government scientific adviser with a rational approach to the climate and energy debate

Sir David MacKay, who has died of cancer aged 48, was a true polymath, a rare breed in today’s world, where the frontiers of scientific knowledge are increasingly remote and complex. It is a testament to David’s intellectual brilliance that he was able to contribute to advancing more than one of these frontiers during his short career.

David latterly achieved cult status among climate and energy aficionados following the publication of Sustainable Energy: Without the Hot Air (2008), initially self-published using £10,000 of David’s own money and offered – as were all his works – simultaneously free for download on his website. Described as a “tour de force” by the Economist magazine and lauded by Bill Gates as “one of the best books on energy that has been written”, within two years it had sold 40,000 copies and been downloaded nearly half a million times.

Government urged to crack down on rogue practice of garages removing compulsory diesel particulate filters from vehicles

More than a thousand diesel cars have been caught without an essential pollution filter that traps deadly particles, according to government figures. But experts warn the rogue practice of removing the filters, which contributes to air pollution-related deaths, could be far more widespread.

Almost 29,000 people die prematurely each year in the UK owing to particle pollution, causing £15bn in health costs. Since 2009 diesel particulate filters (DPFs) have been compulsory in new diesel cars. But, particularly for cars driven in cities, the DPFs can become clogged and cause breakdowns.
