for all humankind

“THE organization shall have no concern with work for military requirements and the results of its experimental and theoretical work shall be published or otherwise made generally available.” The second sentence of the second article of the “Convention for the Establishment of a European Organization for Nuclear Research”, signed by 12 countries on 29 September 1954, was a statement of visionary idealism in a world less than a decade on from the nuclear destruction of Hiroshima and Nagasaki. Such admirable principles led to the vast particle physics laboratory near Geneva, Switzerland, that is now better known as CERN. The model championed by its founders, of peaceable scientific collaboration across borders with results freely available to all, has more than proved its worth. It can be measured not just in the contribution…

vanishing amazon

DESTRUCTION of the Amazon over the past year hit its highest level in more than a decade. Satellite data from the Brazilian space agency gave the first official confirmation that deforestation has soared since Jair Bolsonaro became president in January on a promise to develop the Amazon. Between August 2018 and July 2019, there was a loss of nearly 10,000 square kilometres of forest, the worst since 2008. Logging and burning of the world’s greatest rainforest jumped by 29.5 percent in that period compared with the year before, to 9762 square kilometres. Observers noted that this is the biggest annual increase in more than two decades. It also ends a period of relatively stable losses. The average between 2012 and 2018 was 6727 square kilometres. Gilberto Camara, ex-director of the space agency, tweeted…

starlink obscures images of the sky

ELON MUSK’s SpaceX is interfering with astronomy again, after its second batch of Starlink satellites got in the way of observations. SpaceX launched 60 new Starlink communications satellites into orbit on 11 November, bringing the total number of satellites it has in low Earth orbit up to 120. After the first launch, in May, astronomers noted that the satellites were extremely bright, prompting concerns that the thousands of satellites that SpaceX plans to launch could interfere with scientific research and views of the night sky. The newly launched satellites interfered with astronomical observations at the Cerro Tololo Inter-American Observatory (CTIO) in northern Chile on 18 November. Astronomers were using the Dark Energy Camera (DECam), which can take images of large areas of the night sky in visible and near-infrared wavelengths of light. “I am…

giant virtual universe

A VAST simulation of the universe is digitally recreating the lives of stars, black holes and galaxies. Approximately 1 billion light years across, it is modelling tens of thousands of galaxies. Richard Bower at Durham University in the UK and his colleagues started the simulation last week. It will run non-stop for 50 days across 30,000 computer processors in both Durham and Paris developed by tech firm Intel. The simulation is 30 times larger than one the team ran in 2015, which led to predictions about the mergers of supermassive black holes. The new simulation includes the physics of all the “normal” matter such as the atoms and molecules that make up humans and Earth, as well as the mysterious dark matter that forms around 85 percent of the universe but which…

blasting lead with lasers makes it really strong

LEAD just got an upgrade. When it is quickly compressed with powerful lasers, the typically weak element gets 250 times stronger, making it tougher than hardened steel. The difference between strong and weak materials has to do with how the atoms move against one another. When the atoms are arranged so that they can slide across each another easily, like they typically are in lead, the material is soft and pliable. When they cannot move around so easily, like in iron, the material is hard and strong. Andy Krygier at the Lawrence Livermore National Laboratory in California and his colleagues tested the properties of lead that is quickly pushed to incredibly high pressures using lasers at the lab’s National Ignition Facility. Applying significant pressure also applies heat, so the researchers had to devise…
