Alongside bull sharks and great whites, tiger sharks are one of the main predatory species known to occasionally snack on humans. Their migratory habits may therefore be of some interest if you’re planning to spend a lot of time in the ocean this summer. According to new research, tiger sharks regularly travel over 1000km across the Coral Sea between New Caledonia and the Great Barrier Reef. (Guess you can’t blame ‘em for occasionally getting the munchies.)
As the summer heat continues, many of us turn to air conditioning, but that’s an expensive decision. According to consumer advocate CHOICE, a large air conditioning system will add $530 a year to your power bill, while a ceiling fan will cost $30 a year to run.
Dear Lifehacker, Since it is scorching hot here in Melbourne, I need some tips on how we can keep ourselves cool — particularly if you are currently renting and you are not allowed to install any air conditioning! Thanks, IHate40Degrees
