POST PRESS: A New Oil-Eating Bacteria Discovered

Using more than 200 samples collected from 17 deepwater sites between May 25 and June 2, scientists led by Terry Hazen reported on 24 August 2010 that they found a dominant microbe in the oil plume which turned out to be a new species, closely related to members of Oceanospirillales. It thrives in cold water, with temperatures in the deep recorded at 5 degrees Celsius (41 Fahrenheit).

Scientists from the Lawrence Berkeley National Laboratory noticed this suddenly flourishing bacteria at the oil spill in the Gulf of Mexico. Although still unknown and unnamed, the microbe consumed oil droplets found underwater without significantly depleting oxygen in the water. Oxygen saturation outside the oil plume was 67 percent, while that within the plume was still 59 percent. Oil-eating microbes that consume large amounts of oxygen in the water can potentially create a "dead zone," an area where no oxygen was available, which is dangerous to other life underwater.

Deadly X-Gene Mutants

A RECENT study on macrophages (i.e. defensive cells in our body that engulf threatening substances inside our body) introduced me to a lethal, genetic disease that targets the male population. This disease is called Duchenne muscular dystrophy (DMD), named after the French neurologist Guillaume Benjamin Amand Duchenne, who described it in 1861. While it has an incidence of one in 3,500 newborn males, health experts consider this as the most common lethal disease of childhood around the world. Mutation in the male (X) chromosome [dystrophin gene, locus Xp21] causes a rapid degeneration of the muscles, leading into an eventual loss of walking ability and then death. While females do not exhibit symptoms, they can be carriers of these defective genes, especially if the father had this condition or the mother is also a carrier. Symptoms usually appear before age five; at times visible in early infancy. These symptoms involve... ( Read more .)  This article appears in Sun-Star Ce...

Joy, Temperance and Repose

“I RECKON being ill as one of the great pleasures of life, provided one is not too ill and is not obliged to work till one is better,” wrote Samuel Butler in The Way of All Flesh (1903). The term “antioxidant” was originally used in the 18th century to refer to a chemical that prevents the consumption of oxygen in laboratory experiments. However, in the late 19th and early 20th century, extensive study exploded... ( Read more ) This article appeared in SunStar Cebu newspaper on 02 June 2010.
