Operation Black Gold is about the seizure of an alloy containing 16.67 kg of gold and 39.73 kg of silver in Delhi. The alloy was worth over Rs 10 crore and was seized by the Directorate of Revenue Intelligence (DRI) at FPO Delhi. The Revenue Intelligence Directorate (DRI) acted on intelligence to seize seven shipments of “electrical current/potential meters”. The meters were declared as “current guior machines”. According to preliminary investigations, a systematic syndicate was involved in the gold smuggling. The gold was coated with silver to change its color from yellow to white. The white mixture was then used to make electric meter covers, which were then painted black to avoid suspicion.

Recently, Mesolithic rock paintings were unearthed at Sitamma Loddi, Gattusingaram, in Telangana’s Peddapalli district.

The Mesolithic, or Middle Stone Age, bridged the gap between the Paleolithic and Neolithic periods, spanning approximately 12,000-10,000 years ago. Notable for the transition from large chipped stone tools to microliths, small tools affixed to bone or wood handles for making implements like saws and sickles, it marked a pivotal era in human cultural development.

Researchers recently uncovered a new genus and five novel millipede species in African jungles. Millipedes, not insects but arthropods related to lobsters, crayfish, and shrimp, boast approximately 12,000 global species. These cylindrical or slightly flattened invertebrates, often black or brown, inhabit moist areas with decaying vegetation. Ranging from 2 to 280 mm, they possess multiple segments, each housing two pairs of legs and internal organs. Although not poisonous, some species produce irritating fluids. Nocturnal scavengers, millipedes primarily feed on decaying plants and occasional dead insects.

Notes:
Scientists recently discovered a novel class of virus-like entities called obelisks within the human body. These RNA-based organisms, around 1,000 nucleotides in size, form rod-like structures and differ from known biological agents. Larger than typical genetic molecules like plasmids, obelisks occupy a unique niche between viruses and viroids. Present in diverse areas of the human body, their hosts and potential presence in bacteria remain unidentified, adding intrigue to this recently unveiled class of organisms.
