China relaxes rules for visiting citizens
Article Abstract:
The Chinese government has promulgated new regulations that will allow Chinese citizens who work abroad to return to China and then to go abroad again much more easily than before. The old regulations, put in force soon after the Tiananmen Square massacre in Jun 1989, greatly limited the ability of Chinese researchers and students to live in foreign countries. The new rules, enacted to make China more accessible, will permit anyone with a valid passport and an entrance visa to another country to leave China.

US court rules discovery of gene sequence 'not obvious'
Article Abstract:
The discovery of a novel gene by Thomas F. Deuel and his colleagues from Washington University, St. Louis has been approved for patent rights by the US Federal Circuit Court of Appeals. In a case of patent rights and a major boost to bio-technology industry the court overruled the earlier decision of the US Patent and Trademark Office (PTO). PTO had earlier rejected the claim saying that the genes were very obvious to any one working in this field and hence do not qualify for the patent rights.

Common rules for animals and plants
Article Abstract:
It has long been thought by plant ecologists that the controlling factors in size-density scaling are the geometric properties of individual plants, known as the thinning law. Enquist and colleagues have based their approach to the thinning law on the rate of energy use of individual plants, and have predicted a -4/3 exponent for the thinning relationship. They have shown that plant species can all achieve the same rates of local resource use.
