This carnivorous plant counts to avoid being tricked

view preview
Unlike conventional plants, the Venus flytrap copes with poor soil by eating bugs! But the cost of insect hunting is high. Catching prey requires Dionaea muscipula to snap down quickly and then carry out the energy-intensive process of digestion. To balance the costs and benefits of eating meat, the plants have developed a counting system to identify real prey from false alarms, according to a new study. To understand how the flytrap distinguishes a potential food source from a false alarm like a raindrop, researchers observed the electrical and chemical response of the plant to touch stimulation. In order to mimic insect prey, the scientists stimulated the hairlike sensors located on the plant’s trap. Touching the sensors two times quick ...

This dish will probably turn your stomach

Fruit bat soup is a popular dish in Palau, Micronesia - the bat is served whole! For those that eat fruit bats, their flavor is similar to that of chicken, and that they are clean animals living exclusively on fruit. Bats have a low fat content and are high in protein. Even more interesting, during cooking, bats may emit strong odors reminiscent of urine, because bats spend a significant amount of time in an upside-down position, in which urine and fecal matter may be on their bodies. ...

A Big Mac versus molten copper
|
view preview
Here's what happens when you pour 1 984°F/1 085°C molten copper on a Big Mac. This demonstration has nothing to do with the fact that McDonald's uses preservatives in its ingredients. This is simply a demonstration of the Leidenfrost effect - a scientific principle explaining the phenomena that occurs when a liquid comes in near contact with a solid that is significantly hotter than its boiling point; the surface of the liquid comes to a nearly immediate boil, and creates a thin layer of protective steam. It's much the same effect as when one drops water onto a hot pan and the droplet is seen to dance across the surface. In this instance, the inherent moisture in the burger protects it for a few moments before the copper (at nearly 2 000 d ...

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. ...

Is Nutella even healthy?
|
view preview
Imagine blending modified palm oil, skim milk powder, cocoa, hazelnuts, and whole lot of sugar – that's how Nutella is technically made. In fact, Nutella contains 10.4 percent of saturated fat and 58% of processed sugar by weight. A two-tablespoon (37-gram) serving of Nutella contains 200 calories, including 99 calories from 11 grams of fat (3.5 g of which are saturated) and 80 calories from 21 grams of sugar. The spread also contains 15 mg of sodium and 2 g of protein per serving. You're probably thinking, what if I gather up these ingredients and do it myself, will I have homemade chocolate spread? Not quite. Nutella uses modified palm oil rather than regular vegetable oil because it remains solid at room temperature. This modified oil i ...
