TRIUMF triumph Celebration On 15 December the 500 MeV cyclotron at Vancouver produced its first full energy beams. After a month of gradually spiralling the beam further and further out in the machine, success came precipitately. On 14 December […]

Modern particle physics has teamed up with ancient Egyptian archaeology to discover a void in the Great Pyramid, similar in size to the Grand Gallery but located above it. Kunihiro Morishima of Nagoya University in […]

Gamma rays Since 2008, astronomers have been puzzled by a mysterious feature in the cosmic-ray energy spectrum. Data from the PAMELA satellite showed a significant increase in the ratio of positrons to electrons at energies above 10 GeV. […]

Picture of the month This image shows a nebula named after Edwin Hubble, recorded by the observatory that bears his name. Hubble’s Variable Nebula was discovered more than 200 years ago and later studied in detail by Hubble in […]

Push to develop robust and affordable medical linear accelerators for low- to middle-income countries.

Strategy Innovative ideas and technologies from physics have contributed to great advances in medicine, in particular radiation-based medical diagnosis and treatment. Today, state-of-the-art techniques derived from particle physics research are routinely used in clinical practice and […]

Following the recent observation by the LHCb experiment of a doubly charmed baryon Ξ++cc with a large (130 MeV) binding energy between the two charm quarks, Marek Karliner of Tel Aviv University and Jonathan Rosner of […]

Perfectly natural Following the observation of neutrons and gamma rays in association with lightning, a new study reports evidence that lightning also triggers specific nuclear reactions. On 6 February 2016, Teruaki Enoto of Kyoto University in Japan and […]

Hopes that aging might be defeated by identifying and interfering with culpable genes have run into an obstacle. Paul Nelson and Joanna Masel of the University of Arizona in Tucson have shown that, while competition […]

Neutrino energy Neutrinos are popularly thought to penetrate everything owing to their extremely weak interactions with matter. A recent analysis by the IceCube neutrino observatory at the South Pole proves this is not the case, confirming predictions […]

AAA’s HQ Global healthcare company Novartis has announced plans to acquire Advanced Accelerator Applications (AAA), a spin-off radiopharmaceutical firm established by former CERN physicist Stefano Buono in 2002. With an expected price of $3.9B, said the firm […]

Let there be light At 10.50 a.m. on 22 November 2017, the third-generation light source SESAME in Jordan produced its first X-ray photons, signalling the start of the regional laboratory’s experimental program. Researchers sent a beam of monochromatic light through […]

Experimental The free-electron X-ray laser SwissFEL at the Paul Scherrer Institute (PSI) in Switzerland has hosted its inaugural experiment, marking the facility’s first science result and demonstrating that its many complex components are working as expected. […]

Comparing results The possibility that dark-matter particles may interact via an unknown force, felt only feebly by Standard Model (SM) particles, has motivated an effort to search for so-called dark forces. The force-carrying particle for such hypothesised […]

Ancient tipple Something resembling wine, made from a mixture of grapes, hawthorn fruit wine, rice beer and honey mead, appears to have been made in the Yellow Valley in China around 7000 BC. However, what about wine as […]

In a first for plasma physics, a stable room-temperature topologically confined plasma has been created without the need for external electromagnetic fields. Morteza Gharib of Caltech and colleagues fired a high-speed 100 micron jet of […]
