The mystery of bleach solved at last

You may find it very hard to believe that for over 200 years, scientists have known that bleach kills germs without being able to understand how this happens. Just a few days ago U.S. scientists managed to find how bleach does its dirty work. The active ingredient is hypochlorous acid (HOCl); this acid attacks the proteins in the bacteria, making

Female models and their negative effect on men

We all know that seeing female models can have a negative effect on how women think about themselves, but really, it seems hard to believe that they would have the same effect on men. Still, Jennifer Aubrey, a leading researcher of media effects on body image, completed three different studies that led to the same conclusion: it’s actually men that

America’s vote for science

Science and politics often go hand in hand; they influence one another and despite the fact that the connections are subtle, they often play a crucial role. If at today’s vote was cast only by people who work or support scientific enquiries of any type, the result would be crushing. Today’s importance goes out of the national interest, and dives

Secret of spider-man suit revealed

If you ever wanted to stroll “spidy” your way around the big city, your dream is one step closer to becoming reality, as physicists have found the formula for what they call a “spider suit“. To do this, they applied what they learned from the dazzling gecko and it’s ability to climb walls as well as using the properties of

10 of the most impressive asteroid impact sites

Many people refer to these structures as “Meteorite Craters”, but that’s at least partially incorrect. Meteor is the term used to describe an object that goes through our planet’s atmosphere, and meteorite is used after the object hit the planet. These are just some of the most amazing ones, and easy to see for an inexperienced eye. They are in

A short history of Halloween

The 2008 Halloween is almost here, and it seems to be the word on everybody’s lips this time of year. It’s celebrated mostly in America, but not so many people know about it’s origins, how it developed, and how it’s different from what it used to be many years ago. This is by no means an exhaustive resource, just a

Highest Silicon Solar Cell Efficiency Ever Reached

The efficiency of the solar cells is the first thing needed to be improved in order to improve the quality of the solar panels, and it is the aim of more and more scientists as time passes. Still, very few manage to obtain a breakthrough, and that’s exactly what researchers at University of New South Wales’ ARC Photovoltaic Centre of

9 amazing displays of fossil art

Art is a relative term, especially in these modern times. In its most accepted term, art is the deliberate process of arranging certain elements in such a way that appeals to the senses, trying to achieve beauty. But what these elements are and how they are arranged is up to the artist. So it shouldn’t come as a surprise that

The world’s most advanced microscope

It’s the equivalent of taking the Hubble telescope (before it was damaged) and directing it towards atoms and molecules instead of stars and galaxies, according to Gianluigi Botton, director of the new Canadian Centre for Electron Microscopy at McMaster, where the world’s most advanced and powerful microscope works. It’s called Titan 80-300 Cubed and it was installed in the summer,

Serendipitous events show rare events in distant quasar

According to Murphy’s laws, all great discoveries happen by mistake. This is not the case here, but scientists had the opportunity to observe something they weren’t expecting at all. Astronomers at the University of California-Santa Cruz had the fortune of witnessing the birth of a young galaxy. They were the first to observe the onset of a huge flow of

India launches first mission to the moon

Chandrayaan-1 is the name of the first mission India has ever launched towards the moon, and it was launches succesfully in the morning of October 22, from inside their country. This started the journey which will also imply a major manoeuvre – the lunar orbit insertion – about 2 weeks from the launch date. After it will orbit the moon,

Creating anticancer beer

Every once in a while you hear about such a good idea that you just know it deserves a prize. Such is the idea of a few students from Rice University, who are taking drinking beer to a whole new level; the genetically engineering level. They are entering it in the International Genetically Engineered Machine (iGEM) competition Nov. 8-9 in

Glowing jellyfish earns Nobel Prize

This year’s Nobel Prize for chemistry has been earned by three scientists who researched into the mysterious green glow of a jellyfish. They will split the prize which has been given to them for the discovery and development of the green fluorescent protein GFP. Osamu Shimomura of the Marine Biological Laboratory in Woods Hole, Massachusetts; Martin Chalfie of Columbia University;

Deepest living fish filmed

Nearly five miles below sea level, at 7700 metres to be more exact, in the Pacific oceans, scientists found fish living in the world’s deepest ocean trenches and filmed them. This is the first time a camera has been sent to such a depth. ‘We got some absolutely amazing footage from 7700 metres. More fish than we or anyone in

The man who got his head into a particle accelerator

We’ve all heard stories about soviet scientists, and Hollywood played quite an important role in that. Really few of those stories are actually true, but here’s one that will probably baffle you; it did this to Russian physicists and doctors. First of all, it has to be said that by the time the USSR divided, they had created more than

Rhode Island goes for offshore energy

In the ever developing struggle for alternative energy, Rhode Island made a significant step towards achieving their goal of fifteen percent offshore energy when they awarded Deepwater Wind the right to build a wind farm that will cost more than 1 billion dollars. This will also give the state more green jobs, as well as make it the new leader

The shores of Canada saved animals from climate change

One of our planet’s most significant misteries is the one concerning the massive extinction that took place about 252 million years ago. As it turns out, the shores of ancient Alberta, British Columbia and the Canadian Arctic were a very important refuge for the ancient animals that were threatened; most of the animals that lived at that period were wiped

Blondes really do have more fun, study shows

  It’s often believed that blondes have more fun, but now, we finally have proof for that; scientists claim that not only does bleaching hair does wonders for your look and self-confidence, but it also makes a women feel more attractive, more daring when it comes to asking someone out, and even more adventurous in the bedroom (you need to

‘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
