A Chinese mystery, can you guess what these are?

view preview
The photo shown below was taken at a market in Shanghai, China. Can you guess what they are?If you guessed, water caltrop 菱, you're right! Water caltrops ( Trapa natans) are the seeds of a floating annual aquatic plant that's native to warm temperate parts of Eurasia and Africa. The plant grows in slow-moving water up to 5 m deep, and bear an ornately shaped fruit that resembles the head of a bull or the silhouette of a flying bat. Each fruit contains a single very large, starchy seed. T. natans and T. bicornis have been cultivated in China and the Indian subcontinent for at least 3,000 years for the edible seeds that are used in pastries, served steamed or boiled from street vendors, and even as a remedy for inebriation. ...

An ancient status symbol in China
|
view preview
Started in Imperial China in the 10 th or 11 th century, upper-class court dancers would wrap their feet to make them permanently smaller. Although this made it difficult for a woman to walk, small feet indicated that a woman’s husband did not need his wife’s labor. To make the feet even smaller, sometimes the baby’s feet were broken and wrapped tightly. Some baby’s toes were cut off! Footbinding was banned by the Chinese government in 1911, but continued to be practiced in some places for several decades, as shown in the picture above. ...

The year summer was erased
|
view preview
The eruption of Mount Tambora was so massive, it erased summer that year.The 1815 eruption of Mount Tambora was one of the most powerful eruptions in recorded history. The eruption of the volcano, on the island of Sumbawa in the Dutch East Indies (present-day Indonesia), reached a climax on 10 April 1815 and was followed by between six months and three years of increased steaming and small phreatic eruptions. The ash from the eruption column dispersed around the world and lowered global temperatures, leading to worldwide harvest failures in an event sometimes known as the Year Without a Summer in 1816. The eruption resulted in a brief period of significant climate change that led to various cases of extreme weather. Several climate forcings ...

The Philippine eagle
|
view preview
The Philippine eagle ( Pithecophaga jefferyi), also known as the monkey-eating eagle, is found exclusively in the forests of the Philippines. It has brown- and white-coloured plumage, and a shaggy crest, and generally measures 86 to 102 cm (2.82 to 3.35 ft) in length, weighs 4.7 to 8.0 kg (10.4 to 17.6 lb), and has a 2 meter wingspan. It is considered the largest of the extant eagles in the world in terms of length and wing surface. Among the rarest and most powerful birds in the world, it has been declared the Philippine national bird. Unfortunately, however, it is critically endangered, mainly due to massive loss of habitat resulting from deforestation in most of its range. Killing a Philippine eagle is punishable under Philippine law by 1 ...

One of the world's largest insects
|
view preview
If you're not an insect lover, this is your final chance to turn your head!The giant Malaysian katydid ( Macrolyristes corporalis) is one of the largest insects in the world, with their bodies growing to 15 cm (6 inches) long with a 25 cm (10 inch) long wingspan. Though the last thing you want to hear is that this giant insect is carnivorous, they pose absolutely no threat to humans (aside from haunting your dreams, of course). Relatively speaking, the males of this species have the largest testes of any known animal at 14% of their body weight. If humans had the same ratio, a 91 kg (200 lb) man would have testes that weighed nearly 13 kg (28 pounds)! ...

Flu no more
|
view preview
A promising new drug called baloxavir marboxil (Xofluza) developed in Japan has been shown to stop the flu virus from spreading 24 hours after intake. The drug interferes with influenza A and influenza B's main replication process instead of inhibiting the neuraminidase enzyme, as accomplished by previous drugs such as oseltamivir (Tamiflu) and zanamivir (Relenza). As shown in the illustration, viral neuraminidase sits on the surface of influenza viruses and enables it to be released once reproduced within the infected host cell. Xofluza accomplishes its mode of action by inhibiting the cap-dependent endonuclease activity of the viral polymerase. It achieves this by inhibiting the process known as cap snatching, which is a mechanism expl ...

As mentioned, its central feature is 108-metre-tall (354-foot) replica of the Eiffel Tower of Parisian style architecture, fountains and landscaping (right). It opened in 2007, and can accommodate more than 10,000 residents, although only 2000 residents inhabit the small town. ...

World's newest island

The world's newest island, Niijima, keeps on growing, and is now eight times the size it was when it first emerged off the coast of Japan on 20 November. Having merged with its neighbouring uninhabited island, Nishino Shima - which sat 500 metres away in November - the pair bears an uncanny resemblance to Snoopy the cartoon dog.
