Waste not, want not
In our rush through modern life, we leave behind a mountain of rubbish that gets a little higher every year. The problem starts in our homes—so does the solution.
Jaw-dropping sonar
Like the aperture of a camera lens, bats change the focus of their sonar beam by widening their mouths.

Wasted
Every Monday morning, I join my neighbours, plopping a 45-litre bag of rubbish on the curbside. By 10am it is gone, leaving nothing but a rainshadow.

A delicate balance
Deep in the Mackenzie Basin, the world’s rarest wading bird roams free in the wild, unaware that behind the scenes, a handful of people are trying to solve a problem: how to protect a species that refuses to be contained?

Dr Sacks’ feeling for bismuth
Oliver Sacks, the neurologist and author, died yesterday (Sunday) aged 82. Since he learned he had terminal liver cancer earlier this year, he has been writing some poignant personal essays for The New York Times that have touched a chord with many readers. (Affection for Sacks, author of books with such memorable titles as The Man Who Mistook His Wife for a Hat, An Anthropologist on Mars and Island of the Colorblind) seems boundless. He estimated he received 10,000 letters a year. "I invariably reply to people under 10, over 90 or in prison," he once said.
Kereru fritter, anyone?
Nothing says spring like the start of the whitebait season this past weekend. But aficionados might pause, fork in midair, if they heard freshwater ecologist Mike Joy's comments connecting whitebait and another native species that has been in the news in a culinary connection: kereru. Both are threatened, so, from a biodiversity point of view, eating whitebait is functionally equivalent to snacking on kereru: it hastens the decline. Unlike kereru, however, 'bait can be bought from the supermarket.
P for Paua
A humble New Zealand shellfish with an out-sized foot and a reputation as an aphrodisiac powers a local economy, a $50-million-dollar export industry and an active black market. Recently, a trade in methamphetamine has sprung up in support of poaching efforts. Who will win the battle for control of paua?
Ocean's eleven
At a recent marine sciences conference, I heard the latest update on Maui's dolphin from University of Otago dolphin expert Liz Slooten, and it was not pleasant listening.

Whenever there's a hint of an aurora in New Zealand skies or a supermoon is rising or an interesting conjunction of heavenly bodies occurs (Jupiter and Venus this month), the event makes headlines. The universe fascinates us—and so it should.
In search of a better bee
Unaffected by Varroa, tolerant of cold and able to pollinate in enclosed spaces, bumblebees offer new hope for New Zealand’s primary industries. If only we knew how to build a nest they wanted to live in…
Around the mountains
Those eager to be transported back in time will appreciate the historic townships and relics left behind by Otago’s pioneers. Along the way you can expect to be welcomed by charming locals, served mouth-watering meals, and told stories about the beautiful places they call home. All while experiencing real, heartland New Zealand. Once complete, the trail will allow cyclists an opportunity to explore and discover some of New Zealand’s most secluded and rustic rural settings at a relaxing pace without sacrificing the comforts of home. Cyclists are currently able to ride from Kingston through the towns of Garston, Athol and Lumsden to Mossburn via a wide smooth trail. This section is 85 kilometres long and takes two days. The trail from Mossburn to Mavora Lakes is still in the planning stage. Riders are advised to take a shuttle for this section rather than ride on the road. From Mavora Lakes, a quiet 48-kilometre-long gravel road leads to Walter Peak Station on the shores of Lake Wakatipu. This section is open and ready to ride. The historic Earnslaw ferry then takes riders across Lake Wakatipu to Queenstown. Note that the only accommodation currently available at Mavora Lakes is camping. When fully completed, the Around the Mountains Cycle Trail will be a 180-kilometre, four to five day trip.

New Zealand Mountaineering: A History in Photographs
“Mountaineers climb in pursuit of relaxation, emotional and spiritual refreshment, and the sense of achievement gained from reaching a summit. Though the activity of mountaineering is not always pleasant and is often dangerous, mountaineers climb for pleasure and to achieve self-realisation. These are different satisfactions from those sought by people who enter the mountains to find a new pass, discover gold, or admire scenery.”
