Bluemink (Ageratum houstonianum)

Bluemink (Ageratum houstonianum) is a species of plant in the Asteraceae, an annual herbaceous shrub, cylindrical stems, branching, and green or reddish, white-haired, 0.3-1 meter high, leaves oval to triangular, 2-7 cm long, wide 2-5 cm, green, serrated margins and white hairs.

A. houstonianum has bright blue or red or purple or white flower heads. Flower heads in dense corymbs. The flowers are thread-like and have fine hairs. The lanceolate bracts are narrow, pointed, serrated at the top and glandularly hairy.

This species grows to form dense colonies in grasslands, moist forest clearings and bushes up to an elevation of 1000 meters, prefers cool soil and full sun.

This plant produces a methoprene-like compound that disrupts the normal function of the corpus allatum in insects, the organ responsible for secreting hormones and making insects sterile. This plant is toxic to grazing animals causing liver damage.

Thomas Sutikna lives with Homo floresiensis

BLOG - On October 28, 2004, a paper was published in Nature describing the dwarf hominin we know today as Homo floresiensis that has shocked the world. The report changed the geographical landscape of early humans that previously stated that the Pleistocene Asia was only represented by two species, Homo erectus and Homo sapiens . The report titled "A new small-bodied hominin from the Late Pleistocene of Flores, Indonesia" written by Peter Brown and Mike J. Morwood from the University of New England with Thomas Sutikna, Raden Pandji Soejono, Jatmiko, E. Wahyu Saptomo and Rokus Awe Due from the National Archaeology Research Institute (ARKENAS), Indonesia, presents more diversity in the genus Homo. “Immediately, my fever vanished.
