Canadian Budget Targets Industrial Applications
Canadian scientists are feeling a decided chill in the air after federal Finance Minister Jim Flaherty unveiled the government’s fiscal blueprint for 2013 to 2014. The new budget promises stiffer competition for a smaller pool of research grants. What little new money is made available will again be funneled into targeted “industry-academic” partnerships.

New French Science Law Falls Short of Expectations
Months of consultation with the French scientific community culminated when the science minister presented a draft bill for a new higher education and research law that France’s Parliament will soon consider. [French Parliament, France] Press Release
U.K. Agency Cautiously Endorses Mitochondria Replacement
There is broad public support in the United Kingdom for allowing a new type of IVF treatment that could prevent mitochondrial diseases, the country’s Human Fertilization and Embryology Authority announced. The techniques would introduce new DNA into an embryo, and so it has raised thorny ethical questions. At the same time, the authority advised the government that several safeguards should be included in any proposals for new regulations that would permit clinics to perform the technique.
