This blog has two aims – to share some of the important scientific and conservation stories that are being revealed through shorebird tracking work and to encourage scientists to make their data available via the Global Wader platform. If small numbers of waders are going to be required to carry tracking devices, then it can … Continue reading Making full use of tracking data
The current English breeding population of limosa Black-tailed Godwits is relatively new, arising from a recolonisation in the 1950s that is presumed to have involved Dutch-hatched individuals. Given that the number of breeding birds is small and that there has been a head-starting project to boost the number of locally-raised youngsters for the last few … Continue reading Is inbreeding a problem for England’s Black-tailed Godwits?
It is estimated that 1.5 million pairs of waders breed in Iceland, most of which spend the winter in West Europe and West Africa. There is a lot of guesswork associated with this number and little national monitoring information to assess whether species are doing well or badly. In this context, a 2025 paper in … Continue reading Iceland’s waders in decline
The seven-note whistle of the Whimbrel is a classic sound, welcomed by Icelanders at the end of a long, dark winter. These wonderful waders are responding badly to recent changes to Iceland’s landscape, such as the ever-expanding areas of non-native forestry and power infrastructure. Conservation of the species may be supported by reserving areas for … Continue reading The call of the Whimbrel
Which are the most important migration sites and how are breeding, moulting, staging and wintering locations linked? Forty-four authors have collaborated to bring together ringing, colour-ringing and GPS tracking data in a paper entitled Site-level connectivity identified from multiple sources of movement data to inform conservation of a migratory bird. The analysed data relate to … Continue reading How are migration sites connected?

The profusion of hummingbird feeders in California homes has not only allowed some hummingbirds to expand their range, but has also altered the shape of their beaks. Read more on E360 →
Reversible programs run backward as easily as they run forward, saving energy in theory. After decades of research, they may soon power AI. The post How Can AI Researchers Save Energy? By Going Backward. first appeared on Quanta Magazine
Recent events are very dire for research at US universities, and I will write further about those, but first a quick unrelated survey for those at such institutions. Back in the day, it was common for physics and some other (mechanical engineering?) departments to have machine shops with professional staff. In the last 15-20 years, there has been a huge growth in maker-spaces on campuses to modernize and augment those capabilities, though often maker-spaces are aimed at undergraduate design courses rather than doing work to support sponsored research projects (and grad students, postdocs, etc.). At the same time, it is now easier than ever (modulo tariffs) to upload CAD drawings to a website and get a shop in another country to ship finished parts to you. Quick questions: Does your university have a traditional or maker-space-augmented machine shop available to support sponsored research? If so, who administers this - a department, a college/school, the office of research? Does the shop charge competitive rates relative to outside vendors? Are grad students trained to do work themselves, and are there professional machinists - how does that mix work? Thanks for your responses. Feel free to email me if you'd prefer to discuss offline.
Promise and controversy continues to surround string theory as a potential unified theory of everything. In the latest episode of The Joy of Why, Cumrun Vafa discusses his progress in trying to find good, testable models hidden among the ‘swampland’ of impossible universes.
