In the beginning…the Earth had essentially no free oxygen in its atmosphere. The Great Oxygenation Event came around 2000 million years ago, when cyanobacteria produced enough oxygen for it to accumulate, but only in the past […]

Getting colder [Earlier this year] we reported the bringing into operation of a 45 cm3 polarized proton target working at 0.55 K. It now looks as if the development can be carried further with the testing of […]

Keithley Instruments has announced the Model 2460 SourceMeter, the company’s latest benchtop Source Measure Unit (SMU) instrument with a capacitive touchscreen graphical user interface. Model 2460 offers users higher power sourcing (up to 105 V, 7 A DC/7 A pulse, […]

An oxygen cylinder holds more gas if filled first with a sponge-like powder. Jared DeCoste of Leidos, Inc. in Maryland and colleagues searched among 10,000 metal-organic frameworks using a Monte Carlo simulation, and found two that […]

The term “on paper” often means “theoretically”, but James Collins of Harvard University, Boston University, and the Howard Hughes Medical Institute in Maryland and colleagues have shown that working biological circuits can be printed on […]

For the first time, human stem cells have been converted into insulin-producing pancreatic β cells. Douglas Melton of the Harvard Stem Cell Institute and colleagues report on a complex process that over 35 days produces some […]

Gianotti At its 173rd closed session on 4 November, CERN Council selected the Italian physicist Fabiola Gianotti as the organization’s next director-general. The appointment will be formalized at the December session of Council, and Gianotti’s mandate will […]

A Star Trek-like tractor beam able to stably push or pull semitransparent gold-coated glass spheres over tens of centimetres has been developed by Vladen Shvedov of the Australian National University in Canberra and colleagues. They […]

Just above the surface of the Sun lies the relatively cool photosphere, at around 6000 K, but it turns out to host some remarkably hot explosions. Using the Interface Region Imaging Spectrograph (IRIS), Hardi Peter of […]

GNN On 20–12 September, CERN hosted the fifth annual Mediterranean-Antarctic Neutrino Telescope Symposium (MANTS). For the first time, the meeting was organized under the GNN umbrella. The idea to link more closely the various neutrino telescope projects […]

CM2 at home For the first time, the gradient specification of the International Linear Collider (ILC) design study of 31.5 MV/m has been achieved on average across an entire ILC-type cryomodule made of ILC-grade cavities. A team at Fermilab […]

The ATLAS collaboration has updated its measurement of the production of W bosons in association with jets (W+jets), which is an important channel at the LHC for precision comparisons with QCD. A precise understanding of these […]

The LHCb Collaboration has published the results of a luminosity calibration with a precision of 1.12%. This is the most precise luminosity measurement achieved so far at a bunched-beam hadron collider. LHC beam results The absolute luminosity at […]

The giant slowly awakes The giant slowly awakes, as the process to cool down the LHC continues in the final stage of the first long shutdown, LS1. By mid-October, the last remaining sector, 3-4 (seen here in 2009), had […]

The final straw-tracker module With the end in sight for CERN’s Long Shutdown (LS1), the accelerator chain has been gradually restarting. Since early October, the Super Proton Synchrotron (SPS) has been delivering beams of protons to experiments, including NA62, […]
