Working with the weather to manage parasites of livestock in changing climates

Cabot Institute Blog | 27 October, 2016
Parasites can be found in every environment on earth and infect a wide range of hosts - birds, fish, plants, insects, wild animals, domesticated animals and humans.  When parasites are discussed they often trigger an "ewww" reaction.  However, they have much more serious economic, food security and animal health and welfare impacts when they infect grazing livestock.  Grazing livestock contribute greatly to food security and this is not going to change any time soon.  Not only is the global population (and therefore food requirement) growing, there is an increasing demand for animal-based food products in developing regions and there is an essential role of animal products in marginal environments where crop production is infeasible.  Parasite control is therefore vital, but is not easy to achieve.

#OpenAccessWeek: a bibliography on the impact of open access outside academia

A few years ago, we started the web-site Who Needs Access? to highlight some of the many ways that people outside academia want and need access to published scholarly works: fossil preparators, small businesses, parents of children with rare diseases, developing-world entrepreneurs, disability rights campaigners and many more.

Notes on Symphoricarpos albus or snowberry

Symphoricarpos albus or snowberry is not a plant that is typically noteworthy in western Washington and across a fair bit of northern Washington simply because it is so common. It is also not particularly showy most of the time. It is sort of the Dou...

Investigation-derived waste

Accidental Remediation | 26 October, 2016
I haven't had any field rants recently, so I spent a couple minutes brainstorming, and I realized: I haven't complained about investigation-derived waste (IDW), one of my biggest management headaches! How did that happen?

Central Italy shaken by pair of Earthquakes.

Sciency Thoughts | 26 October, 2016
The United States Geological Survey recorded two significant Earthquakes in Central Italy on Wednesday 26 October 2016. The first had a Magnitude of 5.5 and occurred 7 km to the southwest of the town of Visso in Macerata Province at a depth of 10 km at about 7.10 pm local time (about 5.10 pm GMT), while the second had a Magnitude of 6.1 km and occurred 2 km to the north of the town, again at a depth of 10 km, slightly before 7.20 pm local time (slightly before 5.20 pm GMT). There are no reports of any injuries following these events, but minor damage has been reported across a wide area, as well as power cuts and one instance of a road being closed by a small landslide. People have reported feeling the event across Central and Northern Italy, as well as in parts of Slovenia and Croatia.

Stormwater management is all around you. Can you #SpotTheSCM?

Highly Allochthonous | 26 October, 2016
For a week in October 2016, I had over 38,000 twitter followers as I took a turn hosting the @realscientists account. Of course, I spent a bunch of my time preaching the gospel of stormwater management. Here are tweets over two days synopsizing its history in 140 character bites. (Please note that the account is hosted by a different scientist each week. The image attached to these tweets is that of the current @realscientists host, not a crazy makeover of Anne.)

Archean meteorite impact evidence from the Fig Tree Group in Barite Valley, Barberton Greenstone Belt, South Africa

Mountain Beltway | 26 October, 2016
During the Archean eon of geologic time, the Earth was young, and had characteristics that were both similar to what we find in the modern planet, and also seemed to have some striking differences. Examples of the former: gravity, oceans, and metamorphism. Examples of the latter: a different atmospheric mix of gases, an absence of plate tectonics, and a much hotter internal temperature (of which the komatiites I shared yesterday are one signature).

Sea Ice Extent Is Near Record Lows--South as Well as North

Dr. Jeff Masters' WunderBlog | 26 October, 2016
It's been a banner year for global sea ice, and not in a good way. After a record-smashing mild winter, the Arctic's summer sea-ice melt culminated in a tie with 2007 for the second-lowest extent since satellite measurements began in 1979. The dr...

New Group paper – The Moon: An Archive of Small Body Migration in the Solar System

Earth & Solar System | 26 October, 2016
The Moon's surface is absolutely covered in impact craters. These range in size from the behemoth South Pole-Aitken basin, which is a staggeringly ~2500 km in diameter and 13 km deep, all the way down to microscopic impact craters on glass beads that are less than a millimetre in diameter. No matter the size, the one thing all these impact craters have in common is that that they were created when something smashed into the Moon at high speed on the order of 15 km/sec or more (that's pretty fast when you consider a bullet out of shotgun travels at about 0.9 km/sec).

Getting a Read on Radon: measurement of radon activity in groundwater samples from a proposed fracking site - a student project! James Dinsley

My name is James Dinsley, an Environmental Science student from the University of Nottingham and I am currently a quarter of the way through a one-year placement with the British Geological Survey, working in the Inorganic Geochemistry Laboratories in Keyworth, Nottingham. Over my year with the BGS, I have been supporting projects with Dr Charles Gowing and Dr Andy Marriott looking at the development and validation of (i) a method for determining the amount of radon in groundwater and its application to environmental baseline monitoring at proposed shale gas exploration sites, and (ii) a method of using a form of radioactive lead (210Pb) to determine the age of lake sediments. I will also be working in the aqueous chemistry laboratories, where I will use different chemical tests to analyse the composition of water samples for clients. As part of my work, I have learned how to conduct key laboratory tests such as determining soil pH and organic matter content, water pH and alkalinity, electrical conductivity and total organic carbon.

The Landslide Blog | 26 October, 2016
Today is the my last working day at the University of East Anglia (UEA).  I have the removal company coming in tomorrow, and by the end of the day, all being well, I'll be in a hotel in Sheffield.  I start my new post as Pro-Vice-Chancellor at the University of Sheffield and Professor in the Department of  Geography on Tuesday.
