The fall, recovery, orbit, and composition of the Tagish Lake meteorite: a new type of carbonaceous chondrite

The preatmospheric mass of the Tagish Lake meteoroid was about 200,000 kilograms. Its calculated orbit indicates affinity to the Apollo asteroids with a semimajor axis in the middle of the asteroid belt, consistent with a linkage to low-albedo C, D, and P type asteroids. The mineralogy, oxygen isotope, and bulk chemical composition of recovered samples of the Tagish Lake meteorite are intermediate between CM and CI meteorites. These data suggest that the Tagish Lake meteorite may be one of the most primitive solar system materials yet studied.

Shared goals, shared learning: evaluation of a multiprofessional course for undergraduate students

Twenty-eight undergraduate degree students from seven health care professions attended a two-day pilot course. Using small multiprofessional groups, final-year students from occupational therapy, orthoptics, therapy radiography, nursing, physiotherapy, medicine and dentistry explored professional roles and clinical problem-solving using a theme-based approach. A balance of didactic and interactive small-group learning enabled them to identify issues surrounding multiprofessional teamworking and collaboration in the National Health Service. Evaluation results showed that the course increased knowledge and understanding of other health care professions, developed more positive attitudes and demonstrated the importance of multiprofessional teamwork and communication. Participating students believed that both early and regular opportunities for shared learning should be essential aspects of undergraduate courses.
