It is optional to include date of birth, marital status and nationality but these details do give a clearer picture of the applicant. Education - focus on most recent qualifications with research project titles and brief summaries. You do not need to include a degree course synopsis but do include useful laboratory techniques and areas of knowledge if this is relevant to your application. Describe your duties in two or three lines and highlight what skills you developed in the job. The style of your CV is quite a personal choice.
Boxed sections can look very cluttered.
Avoid a fussy look - make careful use of the bold and underline keys. Try using bullet points for a punchy style. Any longer than 2 - 3 pages and the recruiter's attention may start to wander. Do not go over the top in describing your skills and experience. Complicated language does not come over well.
