Curious Bends – metal-plated insect syringes, white tigers, steppe eagles and more

1. Found: the first metal-plated syringe in a living creature

On a fig tree in the beautiful campus of the Indian Institute of Science, researchers have found a wasp that uses a zinc-plated “syringe” to pierce through the skin of unripe fruit and lay her eggs. What’s more, to reveal this intriguing adaption of nature, they used jury-rigged video equipment to capture close-ups of the wasps. Of course electron microscopy was needed to be sure… still a nice example of jugaad. (3 min read)

2. Everything you know about the white tiger is wrong

The white tiger is not really an endangered species. It’s an oddball animal produced purely for human entertainment. Its natural tropical habitat in India is not good for a predator that has lost its camouflage, and, if any existed in the wild, they would have died out. Instead, they remain in our zoos, suffering from the consequences of severe inbreeding, all because they bring in the crowd and, thus, money. (7 min read)

3. After devouring vultures, diclofenac is eating its way through eagles

After pushing vultures to the verge of extinction in South Asia, the veterinary painkiller and anti-inflammatory drug diclofenac is turning out to be a threat to eagles as well.

4. One social enterprises’s attempt to provide sustainable clean water to rural India

Water ATMs are popping all over small villages outside India’s capital. Clean drinking water is available for ₹1/litre. If the ATM’s tank falls below a certain level, it triggers a text message to the control room to fix the problem. But the uptake of water purchase is nowhere near sustainable. People prefer the free option, even if it is not clean or easy. (5 min read)

5. The simple rule that is China’s weapon to win the war on malaria

From 26,000 cases in 2008, the incidence of malaria in China has dropped to 2,716 in 2012. The reason is that they follow a simple 1-3-7 rule. New cases must be classified within three days and risk to the local area evaluated within seven days. (3 min read)

6. Animated timeline: creation of Indian states from 1951 to 2014
India has a 29th state in Telangana. Economists argue that this is a good thing. New states grow faster than old ones. If they have their way, India may one day have 50 states.

Chart of the week

More than 2 million people responded to the “My World” survey run by the United Nations. They all unanimously agreed that education was their top priority, regardless of the economic background they were from. Action taken on climate change, on the other hand, sat right at the bottom, along with need for reliable energy at home. More from MSNBC here.
