In the late 1980s, staff at the National Marine Mammal Foundation in San Diego, California heard what they thought was the sound of human conversation. They were surprised and delighted when they discovered that the noise was coming from a beluga whale called Noc.
Scientists' fascination with the case has been rekindled by the journal Current Biology, which has published new insights on the story, and posted audio on the internet of the whale in "conversation" mode.
While birds have been known to mimic human speech, it's not a common characteristic among mammals - the few exceptions apparently including Noc and, a decade earlier, a New England harbour seal named Hoover, who reportedly spoke with a Maine accent.
Although marine biologists have confirmed the phenomenon, they don't claim that the animals were attempting communication. But it's an area of research that holds out hope for further understanding of other species.
Noc lived until 2007, but he stopped making human-like sounds after four years, possibly because he had reached sexual maturity. Or perhaps he simply realised there was nothing we humans could tell him that was worthy of a response.
How to get exposure to gold
Although you can buy gold easily on the Dubai markets, the problem with buying physical bars, coins or jewellery is that you then have storage, security and insurance issues.
A far easier option is to invest in a low-cost exchange traded fund (ETF) that invests in the precious metal instead, for example, ETFS Physical Gold (PHAU) and iShares Physical Gold (SGLN) both track physical gold. The VanEck Vectors Gold Miners ETF invests directly in mining companies.
Alternatively, BlackRock Gold & General seeks to achieve long-term capital growth primarily through an actively managed portfolio of gold mining, commodity and precious-metal related shares. Its largest portfolio holdings include gold miners Newcrest Mining, Barrick Gold Corp, Agnico Eagle Mines and the NewMont Goldcorp.
Brave investors could take on the added risk of buying individual gold mining stocks, many of which have performed wonderfully well lately.
London-listed Centamin is up more than 70 per cent in just three months, although in a sign of its volatility, it is down 5 per cent on two years ago. Trans-Siberian Gold, listed on London's alternative investment market (AIM) for small stocks, has seen its share price almost quadruple from 34p to 124p over the same period, but do not assume this kind of runaway growth can continue for long
However, buying individual equities like these is highly risky, as their share prices can crash just as quickly, which isn't what what you want from a supposedly safe haven.

Why does a queen bee feast only on royal jelly?
Some facts about bees:
The queen bee eats only royal jelly, an extraordinary food created by worker bees so she lives much longer
The life cycle of a worker bee is from 40-60 days
A queen bee lives for 3-5 years
This allows her to lay millions of eggs and allows the continuity of the bee colony
About 20,000 honey bees and one queen populate each hive
Honey is packed with vital vitamins, minerals, enzymes, water and anti-oxidants.
Apart from honey, five other products are royal jelly, the special food bees feed their queen
Pollen is their protein source, a super food that is nutritious, rich in amino acids
Beewax is used to construct the combs. Due to its anti-fungal, anti-bacterial elements, it is used in skin treatments
Propolis, a resin-like material produced by bees is used to make hives. It has natural antibiotic qualities so works to sterilize hive, protects from disease, keeps their home free from germs. Also used to treat sores, infection, warts
Bee venom is used by bees to protect themselves. Has anti-inflammatory properties, sometimes used to relieve conditions such as rheumatoid arthritis, nerve and muscle pain
Honey, royal jelly, pollen have health enhancing qualities
The other three products are used for therapeutic purposes
Is beekeeping dangerous?
As long as you deal with bees gently, you will be safe, says Mohammed Al Najeh, who has worked with bees since he was a boy.
“The biggest mistake people make is they panic when they see a bee. They are small but smart creatures. If you move your hand quickly to hit the bees, this is an aggressive action and bees will defend themselves. They can sense the adrenalin in our body. But if we are calm, they are move away.”
