It is said that mercury levels in the Pacific Ocean are rising. It is so dangerous. Because mercury will be methylated by microbes and maculate in marine fish such as tuna. These food will induce human neurotoxin. Now researchers and policymakers are studying methylmercury in fish by atmospheric concentrations of the element. 阅读全文 »

Pollen allergy is called hay fever. Generally cause allergies are those of anemophilous plants, their pollen is dispersed by air currents. Such plants produce large quantities of lightweight pollen, which can be carried for great distances and are easily inhaled, bringing it into contact with the sensitive nasal passages. Around world, about 5 %~10 % people fall in hay fever. Persons may suffer from an itching congested and running nose, a sore nasal-throat cavity, sneezing, caughing, watery and sometimes bloodshot eyes and also perhaps a light thightness of the chest. Other symptoms include: headache, fatigue, inflammation of sinuses and throat. 阅读全文 »

The Union of Concerned Scientists (UCS) says it has determined genetic engineering is unlikely to play a significant role in increasing food production. According to a report by UCS expert Doug Gurian-Sherman released in March 2009. Despite 20 years of research and 13 years of commercialization, genetic engineering has failed to significantly increase U.S. crop yields. 阅读全文 »

From the April 10 issue of 《Science》, scientists say in a study that holds clues to the evolution of green plants. Alexandra Worden and colleagues sequenced the genomes of two strains of Micromonas, which are ancient relatives of land plants and are found throughout the world’s oceans. These genomes reveal features of the ancestral algae that launched the billion-year trajectory of plant evolution and the greening of the Earth. 阅读全文 »
