Credit: STFC New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics. Particle accelerators are best known for colliding matter to probe its make-up, but they are also used … Read more

Sierra Leone rangers fight uphill battle against deforestation

Sierra Leone has one of the highest deforestation rates in the world. As the rainclouds descend on Sierra Leone’s tropical Kambui forest, a handful of khaki-clad rangers assemble for their daily patrol in the fight to preserve the West African country’s dwindling wilderness. The team are from the National Protected Area Authority (NPAA) and are … Read more

Pythons touted as protein alternative

Some experts think the true value of snakes being raised for their skins lies in their meat. In a warehouse in the lush humid farmlands of central Thailand, thousands of pythons lie coiled in containers, rearing and striking at the glass as people pass by. They are being raised for their robust, diamond-patterned skins, which … Read more

Geophysics research finds microplastic pollution increases sea foam height and stability

A wave channel experiment used a zoom lens camera and a custom Python script to process imagery of four different zones: wave generation, shoaling and breaking, air detained by a plunging jet of water, and air trapped at bores where water level rises rapidly. The study provided essential insights into the physical and chemical impacts … Read more

Credit: Wikipedia/CC BY 3.0 Although there is a large body of research on pests evolving tolerances for the pesticides meant to destroy them, there have been considerably fewer studies on how non-target animals in these ecosystems may do the same. In research recently published, Rensselaer Polytechnic Institute’s Rick Relyea, … Read more

Bennu asteroid samples unveiled

Intensive farming could raise risk of new pandemics, researchers warn

Intensive poultry farming in the UK. Credit: Stephen Hinchliffe Industrialized farming is often thought to reduce the risk of zoonotic diseases (those transmitted from animals to humans) because of better control, biosecurity and separation of livestock. A study, led by the University of Exeter, examines the effect of social and economic factors—which are often overlooked … Read more
