‘Green Gasoline’ from sugar

This month, two independent teams have announced that they have succesfully converted sugar-potentially derived waste from agriculture and non-food plants into gasoline, diesel, jet fuel and other chemical substances of high importance. Randy Cortright, a chemical engineer at Virent Energy Systems of Madison, Wisc. announced that carbohydrates and sugars can be processed into a number of substances used as petroleum,

‘Upside down rainbow’ caused by freak weather

Every once in a while we get a sign that the weather around the planet is changing, and not for the good. This kind of rainbow needs very specific conditions to form, similar to those in the North Pole, and it appeared above Britain. Rainbows are formed in a very simple way (details), when light goes through a raindrop for

Energy from space

Our planet needs more and more energy as years pass, and the idea that this energy could come from outer space is getting heard stronger and more often with each passing day. For about 50 years people have been fascinated by this idea and now, John Mankins, president of the Space Power Association made a technical demonstration which led to

Superstar: A MAD Mobile Chinatown

China is developing, exploding and growing. This is how MAD architects begin their presentation of Superstar, a city that resembles no other. It will be featured in the exhibition’Uneternal City’ in Venice, and the project called ‘Superstar: A Mobile China Town’ is an amazing blend of technology and nature, of mankind and outside factors. The Superstar will have the ability

Hubble Finds Unidentified Object in Space, Puzzles scientists

It’s obvious for everybody that more and more interest is being put into space flights, and we’re approaching another era in this field. There’s a good reason why astronauts have it so hard and why they take so many chances; every once in a while, they find something that just bafflesc scientists and that’s impossible to explain, at least at

First pictures of the okapi or the African ‘unicorn’

An African animal so rare that people used to believe it is the mythic ‘unicorn’ has been caught on camera in the wild, for the first time. The okapi is a mammal similar to a deer in the front and to a zebra in the back and with the blue tongue of a giraffe. It was first discovered only in

The First Flight of a New Era

Less than a year from now, in 2009, NASA is going to launch a whole new generation of spacecraft and launch vehicle system. The test flight is called Ares I-X and it will bring scientists even closer to the exploration goals they have set for themselves. The main test objectives are focused on dynamics of the first stage flight, how

7 wonders of modern engineering

In a previous article you had the chance to read about the seven wonders of the ancient world, which remained famous for thousands of years and still amaze people from all over the world due to their magnificent traits. But time passed and nowadays people take pride in other accomplishments, from scientific experiments to stadiums. This list is by no

Century old milestone broken: spotless month for the Sun

Our old Sun has broken a milestone that has not happened for almost a hundred years, as an entire month has passed without a single sun spot being noted. This is relevant because many climatologists believe there is a tight connection between solar magnetic activity which is responsable for the sun spots and climate on earth. Acording to the UCLA

Taking a glance at space food

Astronauts definitely don’t have it easy; preparing and training for most of your life, to go on a mission that is dangerous in most cases, and that has many difficulties to say the least. But perhaps the most interesting aspect in the life of an astronaut is eating. Because there’s not any room for your mother’s pancakes, or your favorite

‘Cutting By Color’; new technique for cancer surgery

One of humanity’s fiercest enemies in the modern world is without a doubt this terrible malady, which has caused an endless number of deaths and suffering; while news and developments in treatment appear every day, there is still no safe receipe for curing it. However, if things get bad, there is now a new technique that allows a more precise

Incredible waster; half of Earth’s food is wasted

It’s hard to believe that about half of the food produced on our planet is wasted, especially when about a quarter of Earth’s inhabitants are suffering from hunger; this, my friends is the wonderful world we live in. Not a world without resources, but a world in which we do not know how to use the resources which are given

9 Dinosaurs that marked the planet

How the dinosaurs appeared is clear, but it’s not so clear how they dissapeared. One thing’s for sure, they ruled this planet for a significant amount of time. But how much truth is behind this avalanche of publicity and fiction, and which dinosaurs are the true leaders of these amazing lizards?? Here’s just a small list, by no means comprehensive

Longest unmaned flight record broken

QinetiQ claims they have broken this record, by using a really light plane built of carbon fiber, powered by solar panels, nicknamed “Zephyr”. The aircraft stayed in the air for 83 hours and 37 minutes, which is more than twice the previous record. Zephyr also broke the previous record by approximately 54 hours, but that attempt remaine unofficial, which is

Ear infections make fat foods sound better

It may seem weird, but ear infections don’t attack only your ears, but your weight too. If you get them during your childhood, there’s a big chance you will develop a taste for fat foods, and thus this affinity will probably lead to obesity. Scientists that made this study suggest that this appears because middle ear infections could affect the

Suicidal bacteria illustrates evolution of co-operation

Bacteria have sometimes behaviour that can amaze scientists, by its complexity and efficiency. Salmonella can commit suicide and help their “brothers” to establish infections that are more damaging, thus helping their species. But scientists believe they have found the answer to this surprising kamikaze behavior. This phenomenon which is called self-destructive cooperation often helps Salmonella typhimurium and Clostridium difficile establish

Science ABC: The Horizon Problem

Today’s topic is a bit more complex, but requires only elementary notions to understand. It’s a problems that scientists have had many problems with, to say the least. The truth is despite the fact that there are some solutions that would partially (or even totally) explain the issue, there is no satisfactory explanation to this Big Bang related topic. Basically,

Adults are easily fooled by children lies

It’s not as if this was a novelty, but now there’s the scientific background to prove it. Actually, this refers more to when children deny something has happened rather than just making things up. Adults to a little better at this one. This research has been made mostly to help in forensic searches, when dealing with cases of child sexual

Potential Alzheimer’s, Parkinson’s Cure Found In Century-old Drug

Every once in a while, you hear about the hardest of problems that have really easy solutions. In numerous cases, cures have been found in most common of substances, or even foods. This time, a study led by researchers at Children’s Hospital & Research Center Oakland showed that in small concentrations, something as common as methylene blue could significantly slow

Green (and not only) reasons why Denmark is the planet’s green leader

The quality of the place of your residence is defined by many characteristics, which include natural and man-made factors, and more or less obvious consequences of those. The thing is if you care about the food you’re eating, the air you’re breathing and the water you’re drinking, Denmark is the place to be at the moment. Also, renewable energy and
