Are we closing in on dark matter?
More than 100 cosmologists, particle physicists and observational astrophysicists are now united in the hunt to determine what is dark matter. Their goal: to take stock of the latest theories and findings about dark matter, assess just how close we are to detecting it and spark cross-disciplinary discussions and collaborations aimed at resolving the dark matter puzzle. So where do things stand?

Schrödinger's cat has a light touch: Quantum physics used to observe delicate systems
A new paper introduces a novel way to observe very delicate bodies based on quantum physics. Researchers in Spain have shown that groups of photons organized in certain quantum states can gently explore the properties of objects in a non-invasive way. The results overcome for the first time a limit imposed by quantum mechanics, and may permit the observation of unknown properties of ultra-sensitive objects such as individual atoms or living cells.

John Lewis obituary
John Lewis, who has died aged 89, used to describe himself as "a mere schoolmaster", and indeed he taught for nearly 40 years at Malvern college, the Worcestershire public school, but he also had a profound influence on the teaching of physics worldwide.He was born in Reading and educated at the Abbey school, Beckenham, then Malvern college, and Pembroke College, Cambridge, where his mathematics studies were interrupted by second world war service at the tank armament research centre at Porton Down, Wiltshire. Soon afterwards, John joined the teaching staff at Malvern and remained there until his retirement in 1983, for ma...

Math formula gives new glimpse into the magical mind of Ramanujan
Dec. 22 marks the 125th anniversary of the birth of Srinivasa Ramanujan, an Indian mathematician renowned for intuiting extraordinary numerical patterns without the use of proofs or modern mathematical tools. A mathematician has now solved one of the greatest puzzles left behind by the enigmatic Indian genius with the development of a formula for mock modular forms that may prove useful to physicists who study black holes.

Inside the Centre: The Life of J Robert Oppenheimer by Ray Monk – review
A life of J Robert Oppenheimer is magnificent in its retelling of a great 20th-century tragedyWhen J Robert Oppenheimer first saw the awful power of the atomic bomb, in the Trinity test at Los Alamos, New Mexico, in 1945, he was reminded of the words in the Bhagavad Gita, "Now I am become death, the destroyer of worlds". Or was he? This famous anecdote actually comes from a documentary made two decades later. At the time, according to the physicist Isidor Rabi, who was there, Oppenheimer was openly triumphalist. "I'll never forget his walk," Rabi recalled. "I'll never forget the way he stepped out of the car… his walk wa...

Physicists make strides in understanding quantum entanglement
While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Recently, theoretical physicists have made important strides in studying a concept in quantum physics called quantum entanglement, in which electron spins are entangled with each other.

Physics on a plane: Helium crystals grown in zero gravity
Physicists from Japan have taken to the skies to grow crystals in zero gravity. Helium crystals were grown using high pressures, extremely low temperatures (0.6K/-272°C) and by splashing them with a superfluid -- a state of quantum matter which behaves like a fluid but has zero viscosity, meaning it has complete resistance to stress. Superfluids can also flow through extremely tiny gaps without any friction.
