Plants normally have only bisexual flowers. Some species, however, also produce male flowers to make the dispersal of pollen more efficient.

SCIENTISTS have enhanced the nutritional value of the potato by inserting a synthetic gene into the plant and are now considering how to use genetic engineering to provide the plant with

The controversial Human Genome Project -- a collaborative effort to decode and understand the human genetic code in chromosomes -- is already showing results and is likely to be completed ahead of

Technological advances allow biologists to sit in their labs and monitor animal movements.

Spacecraft Ulysses passed the largest planet in the solar system and picked up a rich haul of information before heading for the sun on its primary mission.

Specialised structures such as chromosomes were thought to float haphazardly in cells. Now, researchers believe tiny motors guide them on cytoplasmic tracks, a finding that could explain certain genetic disorders.

Evidence suggests plants have a nervous system that enables them to respond to touch.

Certain mouse brain cells have been found to be capable of producing neurons. Scientists say if similar cells are found to exist in the human brain, it will soon be possible to treat nervous disorders.

A BRITISH laboratory and a US firm are collaborating to produce artificial blood after scientists overcame two obstacles that had hampered this effort. Attempts to use haemoglobin isolated from the

ZOOLOGISTS have always wondered why the females of two African antelope species repeatedly mated with only certain males. A further clue was provided by James Deutsch and Rory Nefdt of Cambridge
