Submission + - ODI celebrates New Year OBE for Technical Director, Jeni Tennison (theodi.org)

MrBrainport writes: ODI founders, Sir Nigel Shadbolt and Sir Tim Berners-Lee have welcomed the news that Technical Director, Jeni Tennison has received an OBE in the New Year’s Honours.

Jeni, who grew up in Cambridge, first trained as a psychologist before gaining a PhD in collaborative ontology development from the University of Nottingham.

Before joining the ODI, she was the technical architect and lead developer for legislation.gov.uk, which pioneered the use of open data APIs within the public sector, set a new standard in the publication of legislation on the web, and formed the basis of The National Archives’ strategy for bringing the UK’s legislation up to date as open, public data.

Israeli Scientists Freeze Water By Warming It 165

ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C."
