Darwin’s theory of natural selection illustrates perfectly what evolution is all about, the survival of the fittest if you will. It’s because of natural selection that a crocodile has an armor-like skin to protect it against enemies, a chameleon can change its color and camouflage itself for protection and hunting or humans evolved a more [...]

Researchers studying marine bacteria in the Bahamas’ underwater caves, have made some remarkable discoveries which allowed to understand how these organisms adapt and thrive in rather precarious conditions. Their study might help scientists understand how marine life formed for the first time millions of years in the past, as well as hint how marine life [...]

We at ZME Science love futuristic designs, but above all we love innovative energy efficient solutions. The latest avantgarde lighting set-up from Philips would fit better in an art gallery than in a home, however what it lacks in practicability, it more than makes up in beauty, and moreover in principle – that energy is [...]

Scientists at London’s Imperial College have successfully managed to create biological logic gates, indispensible for the production of electronical devices, simply our of bacteria and DNA. Though the research detailed in a recently published study in the journal Nature Communications was anything but simple, it provides an incredible advancement in the field of biotechnology. “Logic [...]

Ever since uranium has been mined and atomic bombs have been tested, some areas have had to deal with the contamination of sediments and groundwaters by toxic soluble uranium. Now, this problem could be solved with filaments growing from a specific bacteria. Some clean-up methods already use the bacteria to solidify Uranium in sediments, but [...]

The oldest, up to now, fossil has been found recently by a team of Australian and UK geologists, who claim that they’ve managed to discover micro-organism remnants as old as 3.5 billion years. These tiny living cells were actually sulfur feeding bacteria, which didn’t need any kind of oxygen to survive. The fossils were found [...]

As you probably (and should) know already, symbiosis is a close interaction (often long term) between different species, both of which have something to win from this deal. But symbiosis between animals and bacteria… that’s definitely something new. Marine sandy bottoms This kind of environment seems dead, desert-like and empty, but if you were to [...]

Some species of bacteria can survive virtually anywhere: in acids, in nuclear waste, at extremely low or high temperatures, at extreme pressures, and so on; extreme microbes that survive on gases thrown out by Siberian hot springs may have played an extremely important role in the formation of our planet’s atmosphere and its composition, a [...]

We already know about numerous extremophiles, microbes that can live in incredibly extreme conditions, which would easily kill almost every other creature. There are bacteria which survive in extremely high or low temperatures, in substances with an extreme pH, surrounded by nothing but solid rock, in the depths of the ocean, and so on. But [...]

Staphylococcus aureus is a nasty fellow; it can be responsible for a variety of diseases, and it’s pretty resistant to a variety of treatments. But sometimes, it can get an upgrade, and become way more resistant to drugs, which means the staph bacteria becomes much more dangerous and much less treatable. So it’s definitely not [...]
