The British Library has announced that the Klencke Atlas will have its first-ever public showing this summer as part of a map exhibition.
It is almost absurdly huge – 1.75 metres (5ft) tall and 1.9 metres (6ft) wide – and was given to [Charles II] by Dutch merchants and placed in his cabinet of curiosities.

Super Bowl viewers were rubbing their eyes at the sight of a TV spot pairing CBS late-night host David Letterman with longtime NBC archrival Jay Leno, plus media magnate Oprah Winfrey.

A swordfish attack punctured an oil loading pipe in Angola recently, causing a three-day delay in tanker shipments of Girassol crude. Total, the French oil company which operates the pipeline, declared force majeure on shipments. Total later said that swordfish had damaged a flexible loading pipe. Declaring force majeure frees an operator from supply obligations [...]

How many ways can you spell YUMMY!

The day when restaurants will serve garlic grasshoppers or beetle larva skewers is getting closer in Costa Rica, where scientists are “growing” insects for human consumption.
Entomologist Manuel Zumbado’s research into this alternative food source is inspired by practices in Africa, where insects have long been part of people’s diet.
With [...]

Credit card numbers are so passe. Today’s hackers know the real powerhouse data to steal is emission certificates.
That’s exactly what hackers went after last week when they obtained unauthorized access to online accounts where companies maintain their carbon credits, according to the German newspaper Der Spiegel.
The hackers launched a targeted phishing attack against employees of [...]

For those of you into exotic breads, the new “puppy loaf” is both creepy and quite tasty
You often hear people talk about the eye of a storm, but never about the ear, nose, and mouth of the storm. Today’s Top 10 Photos are all about the forgotten orifices of today’s society. (Pics)

According to a new mathematical analysis, the mysterious “3/4 law of metabolism” — proposed by Max Kleiber in 1932 and later described as “extended to all life forms” from bacteria to whales — is wrong.
Apparently, the mysterious “3/4 law of metabolism” — proposed by Max Kleiber in 1932, printed in biology textbooks for decades, explained [...]

Perhaps a little tart in the bathroom?

Mildred’s Temple Kitchen is inviting customers to have sex in its bathrooms. The Valentine’s weekend promotion takes uncomfortable but electrifying sex from the close confines of an airplane and transfers it to the unisex stalls of the Hanna Ave. restaurant.
The Liberty Village restaurant proposes its modern bathrooms become one [...]

Bacteria (Streptococcus pneumoniae, red) under attack by a neutrophil (blue).
Scientists have long pondered the seeming contradiction that taking broad-spectrum antibiotics over a long period of time can lead to severe secondary bacterial infections. Now researchers from the University of Pennsylvania School of Medicine may have figured out why.

In rejecting the soup theory the researchers turned to the Earth’s chemistry to identify the energy source which could power the first primitive predecessors of living organisms: geochemical gradients across a honeycomb of microscopic natural caverns at hydrothermal vents. These catalytic cells generated lipids, proteins and nucleotides which may have given rise to the first [...]

A small but significant proportion of morbidly obese people are missing a section of their DNA, according to new research.
A small but significant proportion of morbidly obese people are missing a section of their DNA, according to research published February 3 in Nature. The authors of the study, from Imperial College London and ten other [...]

Straight out of China comes “The Machismo!” – billed as “the world’s hottest cigarette lighter mobile phone.” Does that mean there’s more than one? Like, are there other, lesser, not-as-hot cell phones with built-in cigarette lighters? Nothing would surprise me after seeing this.
According to the product description on Chinavasion.com…

Forest in Maryland.
Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a [...]

Model of a human brain, with the cerebellum, medulla and brain stem visible at lower left.
The brains of infants who die of sudden infant death syndrome (SIDS) produce low levels of serotonin, a brain chemical that conveys messages between cells and plays a vital role in regulating breathing, heart rate, and sleep, reported researchers funded [...]

New research identifies the ’speed gene’ contributing to a specific athletic trait in thoroughbred horses.
