Guga

image

The tradition.

The controversy.

The taste.

Eating guga is an experience that can produce a lump in the throat, tears in the eyes. Tears of nostalgia, to those for whom it is part of a cultural identity - for others, simply a response to the urge to regurgitate.

The guga is a fishy-tasting seabird, highly prized in its own area for its unique taste. Yet to others living a mere 20 miles away, it is incredible that something so foul can even be taken into the mouth, let alone enjoyed.

The guga, however, is unique to the Isle of Lewis. When exiles meet in far-flung places, the talk soon turns to guga and memories of sharing this . . . delicacy. As the ache of nostalgia creeps in, soon they long to plunge knife and fork into this plump seabird, a 3lb baby gannet. And so it is that barrels of guga, salted down in the summer, wend their way across the world to destinations as far away as New Zealand to bring a taste of home (the sweaty, fishy, oily taste of the scuppers of a fishing smack).

Weird Science – From Whales To Sails

Sperm whales are among the biggest living things on the planet and, surprisingly for these gentle giants, once must have been among the most fearsome. Palaeontologists working in Peru have uncovered the remains of an extinct long lost relative of today’s sperm whale that had 30-40 cm long teeth in both jaws (the modern form has much smaller teeth in the lower jaw only). With jaws more closely resembling those of a killer whale than its thrust/suction feeding relative, scientists believe the newly named Leviathan melvillei was a 15 m long hunter of large prey, probably other whales. Its size, jaws and undoubted intelligence would have made this marine monster more than a match for the giant shark Megalodon with which it shared its home (Science [article], Nature [paper]).

Sperm whales are still the largest animal ever to have teeth, but today their diet consists mostly of squid – including the infamous giant squid – and therein lies a problem. Whereas most land dwelling creatures live on plant material, or some juicy meaty derivative thereof, and hence are essentially “carbon-neutral”, marine animals from penguins to whales feast upon carbon that was probably sequestered in the oceans hundreds if not thousands of years ago, or has weathered out of rocks that are millions of years old. One upshot of this is that carbon dating is notoriously inaccurate on marine organisms, what scientists call the “reservoir effect”, another is that unlike water breathers such as fish, who return this carbon to the oceans, air breathing animals like whales will release this carbon to the atmosphere as CO2 and so contribute to global warming. However in new research published by the Royal Society of London, researchers have calculated that whales have actually offset their carbon emissions with emissions of another kind. Whale poop is iron rich and comparatively liquid, hence returns the excess iron in the whale’s diet back to the oceans in a form that is readily usable by phytoplankton. The team, led by Trish Lavery of Flinders University in Australia, estimate that sperm whales are responsible for removing 200,000 more tonnes of carbon from the atmosphere annually than they actually emit (Royal Society).

But it’s not all good news for the tree-huggers for while whales might be a boon in the fight against climate change, their free-range, organic farming practices of preference are almost certainly not. In a paper published by the National Academy of Sciences, Jennifer Burney of Stanford University and her colleagues have found that intensive farming is by far the most land and carbon efficient method of agriculture. Because agricultural land use is a major contributor to global warming, increasing the yields from farmland, and thereby reducing the amount of land farmed, strongly outweighed the extra carbon emissions of the intensive farming needed to achieve this. Doing the sums on farm outputs since 1961, the team found that increased yields have produced the same as cultivating an additional area the size of Russia at 1961 levels, which would have led to the release of 590 billion more tonnes of CO2, equal to about a third of all man-made emissions since the industrial revolution (PNAS).

And modern farming may be coming to our rescue in another way, as a source of cheap batteries. Almost since Ben Franklin gave up kite-flying, kids in schools the world over have been making batteries out of apples or a potatoes. Now a trio of researchers from the Hebrew University of Jerusalem, led by Alex Goldberg, have found a way to turn these vegetable power sources from classroom curiosities into a viable product. What’s more amazing is the method they discovered to generate a tenfold increase the output of their potato power-pack, they boil the potato first. How did no-one think of this before (AIP)?

Another new idea, albeit a less welcome one, is that one should prosecute scientists for not knowing everything. At least that seems to be the approach taken by the public prosecutors of the Italian city of L’Aquilla, which last year was hit unexpectedly by an earthquake that killed over 300 people and injured 1600 more. The defendants include the head of Italy’s National Institute of Geophysics and the director of the National Earthquake Center along with four other equally prominent scientists and Bernardo De Bernardinis then deputy head of the Civil Protection Agency, who together are looking at being tried for manslaughter for not alerting the population to the imminent disaster at a meeting held one week before the quake struck. It was Bernardinis, a government official, who claimed in a press conference held immediately after the meeting that the scientists had said there was “no danger”, despite the minutes of the meeting clearly showing that at no time was the chance of a major shock ever ruled out (Nature).

Great News For The Environmentally Unconscious

I know you're sitting there thinking "what can we do to make it more energy efficient to drive our cars rather than riding our bikes or walking." You're thinking that because you're lazy and don't want to give up the luxury of automated transportation. Oh. You weren't thinking that? That was just me? Figures. But there's some good news for me. Britain's Environmental Transport Association may have come up with a solution. Piezoelectric crystals. The idea is to embed a stretch of highway with the crystals, then each car that drives over a crystal contributes a tiny bit of energy, such that a single kilometer of roadway could generate 400-kilowatts of energy. That energy could then be collected, stored and used for any number of functions. But will it work? Absolutely. A Sainsbury's supermarket in Gloucester, UK has already put it into use, powering their checkout lanes.

Yes, natural resources will never run out, power will be "too cheap to meter," the utilities love you, and winged cherubs will attend milady's bath.
