Whale carcasses that have sunk to the sea floor are known in the scientific community as whale falls. Around them spring up complex localized ecosystems, which feed off the rich sustenance they provide for decades. The phenomenon was accidentally discovered in 1987 by a team of University of Hawaii oceanographers, who were exploring the ocean depths with a robotic submersible. Many previously unknown species have since been discovered at whale falls. Which organisms thrive in this environment?
Back in the day
For a week in 2005, a choking, smog-like haze brought the central part of peninsular Malaysia to a standstill. Air quality was so poor that a state of emergency was declared in the district of Kuala Selangor and the country's major shipping center, Port Klang. Residents were instructed to stay home, and schools were closed. Only supermarkets and essential services remained open. Miraculously, Kuala Lumpur's main airport was unaffected. What was identified as the primary cause of the haze?

What now-standard gymnastics equipment did Jahn invent?
