Launched in 1977 to study the Solar system's gas giant planets, Voyager 1 is still operating. But now it's so far away that the Solar wind has weakened and a deluge of cosmic particles from intergalactic space is assailing it. Now interstellar space awaits. But where does the Solar system end and this new frontier begin?
-
Scientists at the Large Hadron Collider have found evidence of a new fundamental particle, that could be the much sought-after Higgs boson. In this Naked Science Scrapbook we find out what a Higgs boson actually is, and why finding it could help us understand the structure of the universe a little bit better...

-
What do nerve cells look like, how do they carry information, and how does one nerve connect and communicate with another nerve? Find out in this spine-tingling Naked Science Scrapbook episode...
-
Hydrogen could be a key clean fuel of the future, powering cars, planes and technology. The challenge facing us before we can switch to this energy-dense fuel has been to produce it cleanly and efficiently. Now a team at the University of Birmingham have developed a way of harnessing the power of microbes to make it for us...

Whether you're watching a YouTube video, downloading an email, buying a birthday present or linking up with friends online, you're sending data across the Internet. But how does "the web" actually work, and what lies behind it? Here, in this Naked Science Scrapbook episode supported by 4D Data Centres, all is revealed...
-
Fungi are a biologically important, and often overlooked Kingdom of organisms. In this Naked Science Scrapbook we find out what a fungus actually is, how they live and how they cause and fight disease. Plus we see that many of our favourite meals wouldn't be the same without them.
-
A lot of the metals we use every day, from car wheels to cutlery, are made from alloys. In this Naked Science Scrapbook we find out how alloys are made and how we change their properties to suit our needs. Plus we discover why alloys have a vital role to play when we fly off on holiday...
-
Why do we feel tired or awake at the wrong times when we go on holiday to a different timezone? In this Naked Science Scrapbook we find out how your body clock works, how it is disrupted by long distance travel and if there's any way around getting jetlag.
-
When companies can't back up their data themselves, they often turn to data centres. But what do they do? In this Naked Science Scrapbook, supported by 4D Data Centres, we find out how a data centre is designed to minimise environmental impact, and how they can prevent personal information from being stolen...
-
From DVD players and supermarket scanners to laser pointers and Bond movies, lasers are part of our lives. But just how do they work? In this Naked Science Scrapbook we find out how excitable atoms produce the laser beams and how those beams are used to perform surgery, send information through the internet and even measure the distance to the moon!
-
Huge amounts of energy are lost from power stations and cars as heat. But what if we could harness that heat and turn it into useful electricity? That's what thermoelectric generators or TEGs can help us do. In this Naked Science Scrapbook we find out how they exploit a temperature gradient to produce power and how they're already powering space exploration.
-
Most of us have a microwave oven in our kitchen. They make heating up leftovers and the dreaded readymeal much faster than a conventional oven. In this Naked Science Scrapbook, we find out how the microwave oven produce the microwaves, and how they actually cook the food, plus how popcorn played a key role in the invention of the microwave oven...
-
Every Christmas, one vegetable divides opinion - Brussels sprouts. Some of us love them, some of us hate them, but eating them can have some embarrassing consequences. In this Naked science Scrapbook, we find out why sprouts cause flatulence and what makes sprout-induced gas such an offensive addition to the Christmas table...
-
Millions of people now own compact digital cameras and camera phones that will automatically focus on parts of a scene, without having to turn a focus wheel. But how does autofocus work? In this Naked Science Scrapbook we find out how battleship technology has found its way into cameras and why some autofocus cameras use ultrasound to figure out what to focus on...
-
How do we tell people apart by using their DNA? From murder investigations to paternity testing, DNA fingerprinting is an essential tool in the modern world. But how is it carried out? Find out in the latest Naked Science Scrapbook!
-
Fuel cells may be a major energy source of the future, but how do they work? In the latest Naked Science Scrapbook, we find out how to generate electricity from hydrogen, how fuel cells helped man to get to the moon, and how you could use one to heat your water at home...
-
Cheese is a major (and tasty) part of our diets and humans have been making it for thousands of years? But how is it made? In this Naked Science Scrapbook, we find out how we go from liquid milk to solid cheese and how the blue mould and pungent smell of blue cheeses is formed.
-
Why are some people short sighted and some people long sighted? And how do we use something more usually associated with a Bond villain to correct someone's eyesight? Find out in the latest Naked Science Scrapbook!
-
Being able to fly off on holiday is something we may take for granted. But how does the big metal tube you're flying in stay up in the air? We'll find out in the latest Naked Science Scrapbook. Plus we'll see that if the plane's engines stop working, you won't just plummet out of the sky...
