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." ...

Dental hygiene and the rainforest

Chewing sticks are used by many people instead of toothbrushes. The neem tree grows in many Asian, African, and Middle Eastern countries. Indigenous people in these areas know that chewing neem twigs is good for their teeth. The epidermal tissues contain chemicals that kill bacteria and reduce inflammation. The study of how indigenous (native) plants are used by different cultures is known as ethnobotany.

A fish that spits
|
view preview
Besides what we probably have seen while watching The Little Mermaid - fish singing and playing instruments, Finding Nemo, Shark Tale - whale being cleaned at a whale wash! , or even Spongebob Square pants - making hamburgers that is, have you ever seen or heard of a spitting fish? Well, I have not, until today.. Apparently, the archerfish from the family Toxotidea, literally "spit" to catch their prey. It is like a frog, but upgraded, in the sense that it catches insects and land based prey without a weapon, or a physical means. It just teleports its prey from above water, into the water by knocking it out via shooting water droplets. The missile strength of the water droplet is created and altered based on how far and how big their prey is ...

Why do men have bigger noses than women?
|
view preview
Men’s noses are 10% larger than female's. Males generally have leaner muscles and need more oxygen for muscle growth and maintenance—and larger noses mean more oxygen can be breathed. A new study found that the difference in nose size between males and females of European descent starts showing in early puberty, when 95% of body weight gain in males comes from fat-free mass, compared to 85% in females.

Don't try this at home

A ganzfeld experiment is a technique used in the field of parapsychology to test individuals for extrasensory perception (ESP). It uses homogeneous and unpatterned sensory stimulation to produce the ganzfeld effect, an effect similar to sensory deprivation.The ganzfeld effect has been utilized in many studies of the neuroscience of perception, not only parapsychology. The deprivation of patterned sensory input is said to be conducive to inwardly generated impressions.The technique was devised by Wolfgang Metzger in the 1930s as part of his investigation into the gestalt theory. ...

This is the way scientists doodle
|
view preview
A glimpse into the mind of a Nobel Prize winner - this doodle was made by physicist T.D. Lee during talks with Chen Ning Yang, while both were visiting scientists at Brookhaven National Laboratory in the US in 1956. Their discussions led to radical questioning of one of physics' basic principles and resulted in the duo being awarded the Nobel Prize in Physics in 1957 for discovering that the supposedly absolute law of parity conservation had been violated. ...

Frozen methane bubbles
|
view preview
Abraham Lake lies in the foothills of the Canadian Rockies. The view is breathtaking, especially during wintertime, when methane bubbles freeze right underneath the surface, creating eerie cloud-like formations. The phenomenon has a simple explanation: plants on the lake bed release methane bubbles, which freeze once they’re close enough to the surface. In springtime, when the ice starts to thaw, the gas is released into the atmosphere.

While it's hard to calculate the memory capacity of the human brain, some estimates have put the number closer to 2.5 petabytes. But this is a great rough comparison.

Are silent farts worse?
|
view preview
On average, they are, because they tend to contain more sulphur, which is what gives farts their unpleasant smell. Loud farts, on the other hand, tend to contain more nitrogen, hydrogen and carbon dioxide, which are all odourless gases.

Metal-coated animal
|
view preview
This little guy on the left is the iron sulphide secreting scaly-foot gastropod. It's the only animal known to plate itself with metal and lives in a thermal vent deep in the ocean. But last year scientists found a pale, genetically identical version of the species (on the right) that doesn't secrete metal, leading scientists to question what the purpose of the armour really is.
