Small research teams ‘disrupt’ science more radically than large ones

Posted by in category: science

The current infatuation with large-scale scientific collaborations and the energy they can bring to a scientific domain owes much to the robust correlation that exists between citation impact and team size. This relationship has been well documented in the emerging ‘science of science’ field. Writing in Nature, Wu et al. use a new citation-based index to nuance this conventional wisdom. They find that small and large teams differ in a measurable and systematic way in the extent of the ‘disruption’ they cause to the scientific area to which they contribute.

The application of a new citation metric prompts a reassessment of the relationship between the size of scientific teams and research impact, and calls into question the trend to emphasize ‘big team’ science. The disruptive contributions of small teams to science.

Europe’s next €1-billion science projects: six teams make it to final round

Posted by in categories: biotech/medical, robotics/AI, science, solar power, sustainability

The six newly shortlisted initiatives include: a project that would explore how AI can enhance human capabilities; one to hasten clinical availability of cell and gene therapies; a personalized-medicine initiative; two projects that aim to make solar energy more efficient; and a humanities project called the Time Machine, which seeks to develop methods for enabling digital search of historical records in European cities.

AI enhancement and a virtual time machine are included in the shortlist of pitches.

The Search for New Physics & CERN’s FCC Future Circular Collider

Posted by in categories: astronomy, engineering, environmental, ethics, existential risks, particle physics, physics, quantum physics, science

It is a few years since I posted here on Lifeboat Foundation blogs, but with the news breaking recently of CERN’s plans to build the FCC [1], a new high energy collider to dwarf the groundbreaking engineering triumph that is the LHC, I feel obliged to write a few words.

The goal of the FCC is to greatly push the energy and intensity frontiers of particle colliders, with the aim of reaching collision energies of 100 TeV, in the search for new physics [2]. Below linked is a technical note I wrote & distributed last year on 100 TeV collisions (at the time referencing the proposed China supercollider [3][4]), highlighting the weakness of the White Dwarf safety argument at these energy levels, and a call for a more detailed study of the Neutron star safety argument, if to be relied on as a solitary astrophysical assurance. The argument applies equally to the FCC of course:

The Next Great Supercollider — Beyond the LHC :

The LSAG, and others including myself, have already written on the topic of astrophysical assurances at length before. The impact of CR on Neutron stars is the most compelling of those assurances with respect to new higher energy colliders (other analogies such as White Dwarf capture based assurances don’t hold up quite as well at higher energy levels). CERN will undoubtedly publish a new paper on such astrophysical assurances as part of the FCC development process, though would one anticipate it sooner rather than later, to lay to rest concerns of outsider-debate incubating to a larger audience?
