Extreme light
Across six decades, scientists and engineers have transformed the briefest flash of laser light into ultrafast pulses that pack a powerful punch. Rebecca Pool from ESCI talks to Nobel Laureate, Professor Gerard Mourou, to ...

Einstein–de Haas effect offers new insight into a puzzling magnetic phenomenon
More than 100 years ago, Albert Einstein and Wander Johannes de Haas discovered that when they used a magnetic field to flip the magnetic state of an iron bar dangling from a thread, the bar began to rotate.
Reflections from a Nobel winner: Scientists need time to make discoveries
Since the announcement that I won the Nobel Prize in physics for chirped pulse amplification, or CPA, there has been a lot of attention on its practical applications.
Mini-detectors for the gigantic? Bose-Einstein condensates are currently not able to detect gravitational waves
The gravitational waves created by black holes or neutron stars in the depths of space have been found to reach Earth. Their effects, however, are so small that they can only be observed using kilometer-long measurement facilities. ...
River deep: Einstein's contribution to earth science
Albert Einstein is famous for a lot of reasons, but the movement of sediments in rivers is perhaps not one of them. Yet, his name is associated with those of Ackers, White, and Shields who developed equations to help explain ...
Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos
Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses 'negative mass." ...
Probing quantum physics on a macroscopic scale
Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ...
Letter shows a fearful Einstein long before Nazis' rise
More than a decade before the Nazis seized power in Germany, Albert Einstein was on the run and already fearful for his country's future, according to a newly revealed handwritten letter.
Human eye capable of seeing 'ghosted' images
A team of researchers in the U.K. has found that the human eye and brain are together capable of seeing "ghosted" images. The researchers have published a paper describing their work on the arXiv preprint server.
Centenary of cosmological constant lambda
Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two papers recently published in EPJ H highlight its role in modern physics and cosmology. Although the term was first introduced ...
