By now, you really should be aware of the honeybee problems that are plaguing populations throughout the world – their numbers are dwindling, and this poses a huge threat not just for the bees themselves, but for humans as well. Now, a new study has shown that it’s not just bees who are in trouble, but also other pollinators, like

A most peculiar spider has been discovered by entomologists in the sandy dunes of Morocco’s southeastern desert, Erg Chebbi. Called Cebrennus rechenbergi, the spider can perform flic-flac jumps at almost 2 m/sec, allowing it to swiftly cross the desert. In fact, the common name of the species is the Moroccan flic-flac spider. “Like a gymnast, it propels itself off the ground, followed

The most basic principle of a solar cell is that it works by transferring the energy from an incoming photon (light) to a molecule, which causes one or more electrons to become displaced until an electrical current is formed. That’s the absolute gist of it, only besides electricity, some of the incoming photon energy gets lost as waste heat. Oddly

How humans and squids came to have similar eyes

v6xztx3w-1399041006

Humans and squids are not exactly close relatives – as a matter of fact, we’re really different from squids, so how come we came to have surprisingly similar eyes? The answer, as usually, is in our genes. Eyes are complicated things – and like all organs, they rely on many genes working together, keeping everything fit and tight. Most of the

China has finally clarified the legislation regarding the consumption of endangered species. It remains to be seen if the law will be enforced, but at least, it’s clear for everybody that it is illegal to eat endangered animals or take their body parts for trophies. Poaching, cruelty and endangered animals The phrasing of the legislation was pretty strange, with some

In the US alone, some 34 million tons of plastic waste is generated every year, of which only seven percent gets recycled. The good thing about plastic is that it’s sturdy, cheap and easy to make – these are also its biggest downsides. Plastic is so well built that it can last up to 1,000 years in landslides without degrading, affecting

Tree rings reveal worst droughts in the West’s history happened during Christopher Columbus’ lifetime

Professor Bekker and a student extract a core sample from a dead tree in Provo canyon

Modern climate tracking and water flow records go back only 100 years, but to prepare for the worse, scientists and policy makers alike need to understand how the weather was like in the world many more years prior. A solution is to study the tree rings of certain tree species which bear telltale signs of water levels hundreds of years past,

Small mite is world’s fastest land animal, relative to size

Usain Bolt of the animal kingdom - Paratarsotomus macropalpis.

Cheetahs are the world’s fastest land animals in the world, able to run as fast as 75 mph. It’s their acute agility that allows them to survive, however, catching prey by making huge leaps at four times the acceleration human leg muscles are capable of producing. No doubt about it, this is one of the most amazing cats out there,

When home recycling is concerned, the kitchen reigns supreme. Here is where most of the waste gets disposed and where all the recycling bins can be found, but there’s another important center filled with recyclable items in your home: the bathroom. Research shows that even among families that are consistent recyclers, only 20% of Americans recycle bathroom items. It’s not

Environmental rule regulating mercury emissions saves lives (and $90 billion)

Can you put a cost on pollution? Policy makers, not matter how some may deny it, are more astute than they were a few decades ago about subjects like climate change or global warming. Few can deny the adverse effects of immediate particle pollution on health, but whenever environmental regulations were put forth on the table, cost was a significant
