How molecular motors work in muscle
Article Abstract:
Howard's review article considers the results of experiments with single myosin molecules and actin filaments. Some of Howard's statements are now challenged. Particularly, the use of a value of 4 nm for the working distance of a myosin molecule, while using the same value for the working stroke. Also the stiffness of isolated frog fibre contracting under zero load, implies 20% of heads attached, different from the 1% claimed by Howard. Howard claims to have solved the paradox that the amount of filament sliding occurring is larger than the working distance, by supposing that most of the sliding occurs when the myosin is detached from actin.

The Pulitzer paradox: the more honored the story and distinguished the journalism, the fewer the readers who get to see it
Article Abstract:
Joseph Pulitzer created the Pulitzer Prize in 1916 to honor 14 categories in journalism. Seven additional prizes were set aside for literature, drama and music. Because his will does not allow Columbia Univ from changing rules for the awards, special categories, such as computer graphics or outstanding day-to-day reporting, are not honored. It is difficult for small newspapers to compete with major dailies for these awards. What is more disturbing is that national newspapers do not provide details of the extraordinary newspaper stories that receive the Pulitzer.

Driving test
Article Abstract:
Golf driving range facilities provide players of all ability with the opportunity to practice their sport without incurring membership or green fees. Over 300 ranges currently exist in the UK. More driving range developments are expected. Stand-alone ranges are limited in their provision of suitable services to improve player performance. Other facilities including video bays with play back and tutorial services are available at some sites.
