How to make meat in a lab
|
view preview
The biomass pyramid above shows how a large amount of plant matter is eaten by many small animals which are in turn eaten by fewer numbers of large animals. At each step of the biomass pyramid, matter and energy are lost in the form of energy to keep the animal warm and moving, or as faeces and urine. Therefore, the more steps there are in a biomass pyramid, the more loss of matter and energy that occurs. Humans are usually at the top of the Food Chain or biomass pyramid (unless we are eaten by sharks, lions or bears!). Also, there is often a significant loss of matter and energy at each step that can be avoided. Does that mean that we should all become vegetarians? No. However, we can eat more vegetables and less meat. Food security is an im ...

Do certain foods actually increase/decrease blood pH?
|
view preview
Many people believe that if you eat certain foods, it can cause your blood to become more alkaline or acidic. Medical research studies have clearly shown that breathing and blood carbon dioxide and bicarbonate ions levels are more significant factors in blood-pH control. Alveolar hyperventilation that is common in the sick reduces cell oxygenation, increases resting blood lactate levels, intensifies production of free radicals due to tissue hypoxia (cells are deprived of oxygen), causes diabetic ketoacidosis in the genetically predisposed patients, and suppresses the immune system and main blood-pH buffer systems of the human organism. ...

Why does airplane food taste strange?
|
view preview
If you've been fortunate enough to fly on an airplane, you've probably noticed that the food tastes a bit strange. It turns out that it's not actually because of the food itself (even if you are sitting in economy) but the reduced atmospheric pressure on board and the dry nose and mouth we get from flying, says an expert.

The nastiest cheese on earth
|
view preview
Casu marzu is a traditional Sardinian sheep milk cheese, notable for containing live insect larvae. It is found almost exclusively in Sardinia, Italy. Casu marzu is created by leaving whole Pecorino cheeses outside with part of the rind removed to allow the eggs of the cheese fly Piophila casei to be laid in the cheese. A female P. casei can lay more than five hundred eggs at one time. The eggs hatch and the larvae begin to eat through the cheese. The acid from the maggots' digestive system breaks down the cheese's fats, making the texture of the cheese very soft; by the time it is ready for consumption, a typical casu marzu will contain thousands of these maggots. ...

Birds evolving from fish, a possibility?
|
view preview
A flying fish moves its tail up to 70 times per second to propel itself up and out of the water. Those specialised pectoral fins are spread wide and tilted slightly upward to provide lift, and then folded back against the body to lower the fish back into the ocean. Flying fish (family: Exocoetidae) are eaten by dolphins, tuna, birds, squids and porpoises, so they needed to develop an ingenious mode of escape - such as flying - in order to survive.

Exposure to cold and eating chili peppers both appear to increase the activity of brown fat cells, which burn energy, rather than store it as typical "white" fat cells do, a study has found.

Glow-in-the-dark ice cream
|
view preview
And it's $235 a scoop! The ice cream was created by UK company Lick Me I'm Delicious in time for Halloween, and was inspired by glowing jellyfish. It's made using a synthetic, calcium-activated version of the protein that makes jellyfish luminescent, and lights up when you lick it. However, inventor Charlie Harry Francis didn't offer much reassurance on whether the product was safe to eat, writing on his blog: "Well I tried some and I don't seem to be glowing anywhere, so we'll go with a yes for now." ...

What's the world's most delicious fruit?
|
view preview
Ever wondered why two of the world's most delicious fruits - the mango and the avocado - have such enormous seeds? Turns out they likely evolved to be swallowed whole by megafauna, like our modern-day rhinos and elephants, that once ruled the Earth, to be deposited far away from their host plant and wrapped in a fresh dollop of fertiliser. That's why these seeds are nicknamed 'ghosts of evolution'.

Blood orange!
|
view preview
The blood orange is a variety of orange (Citrus × sinensis) with crimson, almost-blood-colored flesh. The fruit is smaller than an average orange; its skin is usually pitted, but can be smooth. The distinctive dark flesh color is due to the presence of anthocyanins, a family of antioxidant pigments common to many flowers and fruit, but uncommon in citrus fruits. The flesh develops its characteristic maroon color when the fruit develops with low temperatures during the night.

A promising initiative for bees and hotel owners
|
view preview
Luxury hotels in Sydney are now producing their own honey by setting up bee colonies on their rooftops. The Shangri-La already has five rooftop beehives that have produced 14 kilograms of honey since late last year for use in the hotel’s restaurants and kitchens. Considering the amount of honey used in these big hotels, this is a pretty promising initiative!
