As unbelievable as it may seem, some scientists actually took time of their busy schedules to model with mathematical rigor the possibility of a zombie attack occurring, and also discovering possible ways to survive it. The authors of a new study on this issue, which was published in a book on infectious di...

As a yellow main sequence star, it is expected to live a full life of about 10 billion years, but naturally, during this time, it will evolve. Sadly for Ear...

They manage to anticipate most of what could go wrong and learn from past mistakes, so as to get better at what they do. On the other hand, surgeons who do not perform that many oper...

Located in Suwon, 40 km (25 mi) from Seoul, there is the world's first "Toilet House", na... [read more >>] The Wankel rotary engine is another type of internal combustion engine that features a very clever rearrangement of the four elements of the Otto cycle. It was invented by the German engineer Felix Wankel in the 1950s.In the piston engine, the cylinder performs all four steps: intake, compression, combust... [read more >>] There are many historical accounts of spherical lightnings, or "ball lightnings." Although they were once thought to be very rare, a 1960 paper reported that 5% of the US population reported having witnessed ball lightning and another study analyzed reports of 10,000 cases.Ball lightning has the strange te... [read more >>] The hovercraft (to hover - to remain floating, suspended, or fluttering in the air; craft - vessel or vehicle) is an amphibious military or civilian vehicle designed to travel over any kind of surface (as long as it's reasonably flat), being supported by a cushion of pressurized air.It may look weird ... [read more >>] The gamers probably remember the famous "Jet Pack" from the old Command & Conquer: Red Alert series or even from the childish (is it?) Worms game. For those who don't, let me tell you that the jet pack is a concept dating from World War II, when Germany made late-war experiments of strapping two weara... [read more >>] We will look today at what you need in order to make a nuclear fission bomb. You need some money, as it would really help if you were the prince, sultan or other royalty of a small, but rich state. If not, you need to know on a first name basis some evil leader with lots of cash, oil, diamonds and so on, o... [read more >>] The mouse, a computer peripheral that probably doesn't save your life, but it sure makes it a lot easier, has evolved over the years, much like its biological counterpart, adapting itself (well, humans did the adapting for it, actually) to new "environmental" conditions. It's the survival of the ... [read more >>] |
