Policy and farm management help China mitigate climate change

Production of animal protein in China has increased by 800% over the past 40 years. The production was driven by population growth, urbanization and higher worker wages. But the amount of climate-warming nitrous oxide released from animal farming in the country has not risen...

Physics models better define what makes pasta ‘al dente’

Achieving the perfect al dente texture for a pasta noodle can be tough. Noodles can take different times to fully cook and different recipes call for different amounts of salt to be added. Sometimes noodles will stick to each other or the saucepan. Scientists examined...

Researchers show corkscrew elastic waves carry well-defined orbital angular momentum

University of Exeter and Piazza Leonardo da Vinci scientists have shown that corkscrew elastic waves carry well-defined orbital angular momentum. The study has been published in the journal Physical Review Letters. Scientists described experiments they conducted with aluminum pipe and simulations they built. It showed...

Understanding hot spot conditions reached in implosion experiments

Lawrence Livermore National Laboratory researchers described a validation exercise for simple models. These models used to understand hot spot conditions reached in an implosion. These will find good agreement when compared to a set of simulations. Progress toward ignition needs accurately diagnosing current conditions. Accessing...

Super scintillators enable X-ray detection at an ultralow level

The introduction of lead-free metal halide powder into a scintillation screen took some tinkering. KAUST researchers have worked out the right technique. They were able to produce an exceptionally efficient, robust and flexible scintillation film. This will bring significant improvements in medical, industrial and...

New optical tweezers can control luminescent colour using light pressure

One big stumbling block in the field of photonics is that of colour control. To control colour that is the wavelength of light emission, scientists would have to alter the chemical structure of the emitter or the concentration of the solvent. All of it...
