British anglers on alert for alien salmon species

Unusual specimens spotted in UK waters may be product of Russian breeding programme in Arctic Ocean, says conservationist

British anglers have been told to watch out for an alien salmon species that is normally native to the chillier waters of the Pacific and Arctic Oceans.

Eight specimens of wild pink salmon have been caught in the rivers Tyne and Wear, and off the coast of South Shields. The fish is native to the north Pacific basin and its surrounding rivers, and is the smallest and most common of the Pacific salmon.

The Company of Trees by Thomas Pakenham review – memoir of an intrepid tree obsessive

From seed-hunting expeditions in the Andes to grim encounters with the timber trade, this memoir of an intrepid tree obsessive stands tall

Few have ever indulged their inclinations on a grander scale than Thomas Pakenham, whose passion is for trees. The scarlet maple was his first love, the ginkgo remains his favourite, and he would give his eye teeth for a Magnolia sargentiana. He says he is prepared to die for the silver fir that guards the approaches to his crumbling Irish castle, where the blue pine in his Chinese garden waggles her sinuous brown hips for him “like a dancing girl … in a shimmering skirt of blue-green needles”.

This is an exuberant tale of greed and gratified desire by a romantic who, for 50 years and more, has been planting trees by the thousand on his family estate at Tullynally in Westmeath. Pakenham is currently in his 82nd year, and buying magnolias like a madman “in what the Germans call Torschlusspanik” (last-minute or door-closing panic). He wants a packet of monkey puzzle seeds from Patagonia so that “when I am old I shall look up from my wheelchair lost in a forest of monkey puzzles”. They grow 20cm a year at best, so there should be plenty of time for further instalments of Pakenham’s ongoing tree saga that started nearly 20 years ago with Meetings with Remarkable Trees. His fourth volume, The Company of Trees, chronicles a year in its author’s life of planning, planting and travelling in pursuit of the great plant-hunters, Joseph Hooker, George Forrest and Ernest Wilson, who scoured the world for 19th-century garden-builders like the Williamses at the Cornish castle of Caerhays, and the Holfords of Westonbirt in Gloucestershire.

Celebrated NASA planet hunter shifts his sights back to climate change on Earth | Dana Nuccitelli

William Borucki donated Shaw Award prize money for pioneering planet finding to the Union of Concerned Scientists for its climate change efforts

William Borucki has had an amazing scientific career. One of his first jobs was at NASA Ames Research Center, where he worked on the Apollo moon missions, including helping to develop the heat shield for the space shuttle. After the successful moon landings, Borucki shifted to NASA’s Theoretical Studies Branch in the 1970s, where he developed models of the Earth’s atmosphere to predict the effects of nitric oxides and chlorofluoromethanes on the ozone layer. Both were determined to contribute to the problem of ozone depletion and the hole in the ozone layer.

In the 1980s, Borucki began advocating the development of a space mission that could detect Earth-size planets. He published a paper in 1984 showing that a photometer 1,000 times more precise than any in existence could detect Earth-size planets. Undeterred by rejections of four proposals in the 1990s for a planet-finding mission, Borucki was ultimately appointed Principal Investigator in 2001 for NASA’s new Keppler Mission to discover these planets. During its four years of its operation, the Keppler Mission discovered over 4,600 planetary candidates, confirmed more than 1,000 as planets, and made numerous contributions to stellar astrophysics.

Renewable energy outstrips coal for first time in UK electricity mix

Wind, solar and bioenergy surge to supply a record 25% of the country’s electricity for a whole quarter

Renewable energy has for the first time surpassed coal in supplying the UK’s electricity for a whole quarter, according to government statistics released on Thursday.

The revelation of the surge in wind, solar and bioenergy to a record 25% comes in a week when the government has been heavily criticised by business leaders and Al Gore for cutting support for clean energy.

Turning Waste Cotton Into A New Fibre

A group of Finnish organisations have launched a project to experiment with a new cellulose dissolution technique that transforms old disused cotton clothing into brand new fibres that can be utilised freshly in the textile industry.

There is plenty of optimism surrounding this project. The cellulose “wet-spinning” is expected to begin in a plant in Finland this October with a new clothing line made using exclusively the new recycled fibres expected to be ready for release by the end of 2016.

The project aims to bring together recent advancements in recycling technology and growing business demand for ways to improve the lifespan and maximise the use of materials and products, including textiles.

It has been found that cotton that cannot be reused can still be dissolved to make a cellulose solution, which can be turned into new fibres. These fibres are produced using a similar technique to the one that has been utilised in viscose fibres for decades, but the Finnish project leads state that the new production method is not toxic in comparatively and more cost effective from a water and energy use perspective.

Superpod of leaping dolphins delights sightseers in Costa Rica – video

Orlando Marin, who posted his footage to Facebook, says they numbered in the thousands. Such a large gathering can be the result of abundant food in the area, or can happen spontaneously
