We are beginning to be able to control very precisely how light interacts with matter, creating opportunities for invisibility, soundproofing and even earthquake damage prevention.

A new technique could help the police identify more criminals from just their footprints.
A bold theory suggests the Vikings may have used a mysterious method of studying sunlight to navigate the oceans.
It might be that teaching people to reframe their thoughts about winter can help them overcome seasonal affective disorder year after year.
Darkness is precious to astronomers, but it’s also good for everybody. We should ensure we preserve the dark by using the latest technologies responsibly.
Many people think relativity puts a hard speed limit on the universe, but it actually opens up the possibility of faster-than-light travel - if we can overcome some significant practical hurdles.
Solar is a vital piece of the energy puzzle for Africa, but there is an insect problem that comes with the light from solar.
Is electricity making us sleep less? A new study on sleep in preindustrial societies suggests the answer is no. But it misses a big point: people in preindustrial societies spend more time in darkness than we do.
Why do certain songs and colors make us feel a certain way?
Suprising discovery of fundamental property of light could lead to applications in optical communications, metrology and quantum information processing.
The field of plasmonics has implications for integrated circuits, biosensors, other light-based technologies – even invisibility cloaks.
The 13th century polymath Robert Grosseteste was ahead of his time when it came to understanding light, colour and the universe itself.
During these dark winter months, spare a thought for artificial lights. From strings of lights adding holiday cheer to artificial sunlamps alleviating seasonal affective disorder, they brighten our days…
Graphene – an atom-thick sheet of carbon – has been touted as a new wonder material: it is stronger than steel and conducts electricity better than copper. In the journal Nature Nanotechnology today, my…
Light pollution disrupts the natural reproductive cycle of lemurs a new study has found. Male lemurs are sexually inactive…
Most of the time we take light for granted. It arrives with the sunrise everyday and we turn it on with a flick of a switch every night. It appears to be ephemeral and benign to us humans but there is…
If you’re in Melbourne or Sydney over the next couple of weeks, you can enjoy the nightly transformation of some familiar urban landmarks. How should we understand this growing global enthusiasm for spectacular…
Cosmologists have detected a long sought component in the Cosmic Microwave Background (CMB), which will help us to further…
The West African Gaboon viper’s pattern of cream, yellow, brown and black scales helps it blend in with leaves, but a new…
All of the light we see around us comes in chunks of energy known as photons. As well as making up light, photons can be used to carry and process information and their quantum properties make possible…
