A deep-ocean crewed manoeuvrable submersible that became the 9 meter long called Alvin. It turned out to be a vehicle for unexpected science, very much in the Al Vine mould. Though all its activities are now filtered and controlled by the dead hand of peer review, the unexpected still shows through. And the science...

Neural networks are not cognitive machines. But they achieve in a way more like biological brains than digital computers. This shows in their ability to handle imprecise data and to learn from experience. The capabilities of a neural computer depend entirely on the number of processors and the complexity of connections...

An autonomous underwater robot bristling with sensors is helping researchers to find out what goes on in turbulent water. Using a new sonar system, it can analyze the water over scales ranging from millimeters to tens of meters to answer questions such as how the momentum of a tropical cyclone is transferred from the...

Human body is gifted with many organs with equal importance. The sensory organs keep the whole body active and in maintain the equilibrium of the whole body. Different organs do multiple actions and after every action they send signals to the brain and our brain responds to them with the same speed. This all happens at...

Technology means application of science to any particular field. It has been rightly said that necessity is the mother of invention. Since the prehistoric times, man has been looking for ways and means to improve his way of living, the present is pushed by the past and pulled by the future; we manage our daily...

Herpetology was the study of reptiles and amphibians. Many biologists have an identity crisis. Names such as herpetologist, entomologist and mycologist are just not fashionable. Much preferred are rather broader titles such as ethologist, immunologist and endocrinologist. A survey of biologists who classify themselves...
