In 2006 (yes, it was that long ago – yikes) the International Astronomical Union (IAU) officially adopted the definition of dwarf planet – they are large enough for their gravity to pull themselves into a sphere, they orbit the sun and not another larger body, but they don’t gravitationally dominate their orbit. That last criterion […] The post Where Are All the Dwarf Planets? first appeared on NeuroLogica Blog.
Remember CRISPR (clustered regularly interspaced short palindromic repeats) – that new gene-editing system which is faster and cheaper than anything that came before it? CRISPR is derived from bacterial systems which uses guide RNA to target a specific sequence on a DNA strand. It is coupled with a Cas (CRISPR Associated) protein which can do […] The post The New TIGR-Tas Gene Editing System first appeared on NeuroLogica Blog.
Small nuclear reactors have been around since the 1950s. They mostly have been used in military ships, like aircraft carriers and submarines. They have the specific advantage that such ships could remain at sea for long periods of time without needing to refuel. But small modular reactors have never taken off as a source of […] The post Are Small Modular Reactors Finally Coming? first appeared on NeuroLogica Blog.
The flying car is an icon of futuristic technology – in more ways than one. This is partly why I can’t resist a good flying car story. I was recently sent this YouTube video on the Alef flying car. The company says his is a street-legal flying car, with vertical take off and landing. They […] The post The Alef Flying Car first appeared on NeuroLogica Blog.
I am fascinated by the technologies that live largely behind the scenes. These are not generally consumer devices, but they may be components of consumer products, or may largely have a role in industry – but they make our modern world possible, or make it much better. In addition I think that material science is […] The post Thermoelectric Cooling – It’s Cooler Than You Think first appeared on NeuroLogica Blog.

In math and computer science, researchers have long understood that some questions are fundamentally unanswerable. Now physicists are exploring how even ordinary physical systems put hard limits on what we can predict, even in principle.

Non-blog life has been very busy, and events have been changing rapidly, but I thought it would be a good idea to give a brief bulleted list of updates regarding the NSF and associated issues: A court decision regarding who has the authority to fire probationary federal workers has led to the NSF hiring back 84 of the employees that it had previously dismissed, at least for now. The Office of Personnel Management is still altering their wording on this. There is likely some kind of continuing resolution in the offing in Congress, as the current funding stopgap expires on March 14. If a CR passes that extends to the rest of the fiscal year (Sept 30), that would stave off any big cuts until next FY's budget. At the same time, a number of NSF-funded research experience for undergraduate programs are being cancelled for this year. This is very unfortunate, as REU programs are many undergrads' first exposure to real research, while also being a critical mechanism for students at non-research-heavy institutions to get research experience. The concerns about next year's funding are real. As I've written before, cuts and programmatic changes have been proposed by past presidents (including this one in his first term), but historically Congressional appropriators have tended not to follow those. It seems very likely that the White House's budget proposal will be very bleak for science. The big question is the degree to which Congress will ignore that. In addition to the budget, agencies (including NSF) have been ordered to prepare plans for reductions in force - staffing cuts - with deadlines to prepare those plans by 13 March and another set of plans by 14 April. Because of all this, a number of universities are cutting back on doctoral program admissions (either in specific departments or more broadly). My sense is that universities with very large components of NIH funding thanks to medical schools are being particularly cautious. Schools are being careful because many places guarantee some amount of support for at least several years, and it's difficult for them to be full-speed-ahead given uncertainties in federal sponsor budgets, possible endowment taxes, possible revisions to indirect cost policies, etc. Enormous uncertainty remains in the wake of all of this activity, and this period of comparative quiet before the staffing plans and CR are due is an eerie calm. (Reminds me of the line from here, about how it can be unsettling when a day goes by and you don't hear anything about the horse loose in the hospital.) In other news, there is a national Stand Up for Science set of rallies tomorrow. Hopefully the net impact of this will be positive. The public and our legislators need to understand that support for basic science is not a partisan issue and has been the underpinning of enormous economic and technological progress.
