Eighty percent of North Americans can no longer see the Milky Way at night. But the problem with light pollution isn't just about stargazing.
Yoghurt. Nuts. Yes or no?
What's the deal with fat in our foods and drinks? Should we avoid it?
A new development could mean vastly increase data transfer over optical fibre cables.
The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.
Drawing and reality: designing a metamaterial pattern. On the left is the plan; on the right is the actual object.
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.

It might be that teaching people to reframe their thoughts about winter can help them overcome seasonal affective disorder year after year.
The Dreamtime constellation of The Emu rises out of the glow of Sydney, 350km away from the Australian Astronomical Observatory.
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.
Hyperspace may one day be a reality.
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.
Disase carrying insects are attracted to light bulbs – a constraint of domestic solar energy.
Solar is a vital piece of the energy puzzle for Africa, but there is an insect problem that comes with the light from solar.
Not dark enough.

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.
The electronic band STS9 is known for having intoxicating light shows accompany their live performances.
Why do certain songs and colors make us feel a certain way?
Scientists have shed light on light.
Suprising discovery of fundamental property of light could lead to applications in optical communications, metrology and quantum information processing.
The beauty of stained glass – all down to electron oscillations.
The field of plasmonics has implications for integrated circuits, biosensors, other light-based technologies – even invisibility cloaks.
The Greatest Mind You’ve Never Heard Of.
The 13th century polymath Robert Grosseteste was ahead of his time when it came to understanding light, colour and the universe itself.
Light of every hue.
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…
Feel the lift from the light.
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…
