Record-breaking dive in Antarctic waters emerges after scientists accidentally tagged wrong emperor penguins

Scientists in Antarctica have recorded the world’s longest penguin dive, an astounding 32.2 minutes under the water; a full five minutes longer than the previous record.

Emperor penguins, which live only in Antartica, are the tallest and heaviest penguins in the world, and have the best diving ability. They can dive as much as 500 metres down in some of the world’s harshest and coldest seas.

Critics say retailers can pick and choose whether to sign up to Plastics Pact, a series of pledges that have no enforcement mechanism

UK supermarkets and food companies launched a new voluntary pledge to cut plastic packaging on Thursday as ministers consider forcing them to pay more towards collecting and recycling the waste they produce.

In a first response to a growing public backlash against the huge volumes of plastic rubbish, most of the UK’s largest supermarkets signed up to support the UK Plastics Pact – an industry-wide initiative which says it aims to transform packaging and reduce avoidable plastic waste.

Those dedicated to going plastic-free wonder how to dispose of cat litter or buy cleaning products sans packaging. Share your problems – and solutions

• Going plastic-free is as easy as calico bags and reusable coffee cups
  

Plastic has become an environmental disaster. Microplastic pollution has been found in our waterways, fish stocks, salt, tap water and even the air we breathe. Reducing our reliance on plastic by refusing it wherever possible has never been more important, especially as Australia’s recycling system is in crisis.

Yet there are conundrums that continue to defeat even those dedicated to going plastic-free. From bin liners to takeaway containers, Guardian Australia has tried to solve them. And we want to hear from you: share your plastic conundrums and the solutions. We’ll round up the best ideas for a follow-up article.

Larger-than-expected population in Africa gives hope for species survival, scientists say, but animal remains critically endangered

There are far more gorillas left in the world than previously thought, according to a landmark new survey, with numbers as much as double earlier estimates.

However, their populations are continuing to fall fast, down 20% in just eight years, leaving them critically endangered. Furthermore, 80% of the remaining gorilla troops do not live in protected areas, leaving them vulnerable to the threats the researchers summarise as “guns, germs and [felled] trees”.

Low-lying atolls around the world will be overtaken by sea-level rises within a few decades, according to a new study

Hundreds of thousands of people will be forced from their homes on low-lying islands in the next few decades by sea-level rises and the contamination of fresh drinking water sources, scientists have warned.

A study by researchers at the US Geological Survey (USGS), the Deltares Institute in the Netherlands and Hawaii University has found that many small islands in the Pacific and Indian Oceans will be uninhabitable for humans by the middle of this century. That is much earlier than previously thought.
