Detecting gravity waves is a major goal for astrophysicists. We know they should be there, but we haven’t found them yet. But today we are one step closer. By literally squeezing light on a quantum level…
Welcome to Peer Review, a series in which we ask leading academics to review books written by people working in the same field. Here Geraint Lewis, Professor of Astrophysics at the University of Sydney…
It inspired the 2010 Nobel Prize in Physics. It’s the best thermal conductor we know of. It’s a crystal stiffer than diamond, but able to stretch by 20% of its length, and can carry a current density one…
How long’s a piece of string? You may want to sit down for a minute.
Gnu2000
String theory entered the public arena in 1988 when a BBC radio series Desperately Seeking Superstrings was broadcast. Thanks to good marketing and its inherently curious name and features, it’s now part…
Theoretical physics strives towards a (beautiful) description of everything.
Jinx!
The “traditional” beauty of theoretical physics is its equations. If we want to describe something, or the way something behaves, we can write down a relation between some properties we think that thing…
Welcome to If I had a blank cheque … a series in which leading researchers reveal what they could (and would) do in their discipline if money were no object. Today we hear from Dr Jonathan Carroll, Postdoctoral…
You wouldn’t believe what modern telescopes can do.

Last week, scientists set a new distance record, seeing a burst of gamma-rays from a star that exploded when the universe was only 520 million years old. The light from this distant source has been travelling…
Economists and physicists may seem like unlikely bedfellows, but then opposites often attract. Their union has recently produced a peculiar baby, a field of research known as “econophysics”. Physicists…
Could this kitty be both dead and alive? Well, erm, you decide …

Quantum teleportation has been in the news before but last week Japanese and Australian scientists went one better, managing to teleport every physicist’s favourite feline: Schrödinger’s cat. Before you…
Quantum mechanics (the theory of atoms, quarks and photons) is definitely weird and, thanks to the work I’m doing, it might be getting weirder. Allow me to throw a quantum spanner in the works. In the…
As yet we can only guess what the Higgs boson might look like.
DESY Zeuthen
Theoretical physics is full of mysteries and unknowns. In the case of some particles, we can predict their existence even if we can’t find them. Such is the status of the Higgs boson. And yet detecting…
Nanoparticles, as used in sunscreen, are readily absorbed by the body.

For the public, the jury is still out on nanotechnology – the media simultaneously extols its promise and warns of the potential calamity facing humanity. But what is it? How does it work? Is it dangerous…
Is the “Z-prime” lurking within a “jungle” of particles at the LHC?
Argonne National Laboratory
There’s nothing like an unexpected result to get physicists excited. So in 2008, when some strange behaviour was detected from a rarely-produced particle known as the “top quark”, there was much interest…
Time travel has long been a staple of science fiction but the LHC might make it a reality.
Fabrice Coffrini/AFP
Switzerland’s Large Hadron Collider (LHC) can be called a time machine in one sense: it enables us to examine conditions as they were during the universe’s early stages. But is the 27km-long particle accelerator…
Could neutrinos be responsible for the shape of the universe?
The Super-Kamiokande Neutrino Detector, Japan
Of all the known particles in our universe, neutrinos are perhaps the most elusive; their origins are mysterious, their purpose unknown and they are notoriously difficult to detect. You’ll already know…
