Geostachys annamensis is one of Vietnam’s endemic gingers – the species was described in 1921 with specimens collected in Da Lat City by Henry Nicholas Ridley Cecil Boden Kloss (1877–1949), a British zoologist (on animals and birds) during a survey in Lang Biang Plateau, in Da Lat in 1918 and identified by Henry Nicholas Ridley (1921) from the Plant Department of the British Museum. Geostachys annamensis bush (Photo by Truong Ba Vuong) So far, only about 10 specimens have been studied, in Hanoi, British museum and Paris (including only two specimens correctly identified as G. annamensis. However, there is no representative sample for VNM specimens in ITB. All these collections are derived from Lam Dong province. The last collection was done in 1980 in the Central Highlands programme.

Coral reef is estimated to cover over 284,300 km2, with Southeast Asia accounting for 32.2%. Coral reefs are home for more than 4,000 tropical fishes and fishes living in coral reef with high economic values, such as groupers (Serranidae), snappers (Lutjannidae), and emperors (Lethrinidae).Increasing demand on the global fresh fish consumption market leads to the exploitation and extermination of fishes most coastal coral reefs, which are spawning areas. Hot spots for fishing exploitation are concentrated in places where large number of fish spawn. The use of destructive fishing methods such as explosives and xyanua destroys spawning areas of coral reef fishes and increases the danger of severe decline in fish larva providing resources to nearby reefs.
Experts in botany from the Institute of Southern Bionomics under the Vietnam Academy of Science and Technology (VAST) have discovered and made public a new species named Leonid crocus (Curcuma leonidii Škorničk. & Lưu).
“Research on marine geology and geophysics” is a scientific publication of the Institute of Marine Geology and Geophysics (IMGG). The Vietnam Academy of Science and Technology covered part of the expenses to introduce research results in the fields of geology, geochronology, tectonics, deep architecture, environmental geology, remote sensing, geophysical schools (magnetic fields, gravity and seismic activity), atmospheric physics, oceanography physics, environment and marine sources by scientists.
At 04:48 am Japan time (02:24 am Vietnam time) on August 4th 2013, at Yoshinobu launching pad at Tanegashima space centre, Vietnam’s micro satellite Pico Dragon was carried into space on Japan’s HTV-4 (Kounotori 4) cargo spacecraft.
Organic substances, N and P from daily sewage and human production activities are the main causes for eutrophycation in freshwater. The interior surface waters of Vietnam, especially lakes and water reservoirs, are increasingly eutrophic, with the outbreak of microalgae, including toxic Cyanobacteria discovered in Microcystis aeruginosa, causing ecological imbalance and water quality decline.
