Antibacterial phages combined with magnetic nanoparticle clusters effectively kill infectious bacteria found in water treatment systems. A weak magnetic field draws the clusters into biofilms that protect the bacteria and break them up so the phages can reach them.

NASA continues to study pulsars, 50 years after their chance discovery
These rotating 'lighthouse' neutron stars begin their lives as stars between about seven and 20 times the mass of our sun. Some are found to spin hundreds of times per second, faster than the blades of a household blender, and they possess enormously strong magnetic fields.
New imaging tracer allows early assessment of abdominal aortic aneurysm risk
Researchers have developed a way in which medical imaging with SPECT/CT could potentially be used to assess a patient's rupture risk for abdominal aortic aneurysm. Delaying surgical treatment can be life-threatening, and this new type of imaging could allow physicians to diagnose disease and better plan its management.
Technique enables printable and rewritable color images
A chemical process that allows color images to be printed on specially coated paper and then erased so that different images can be printed on the same paper has been developed.
Magic helps unmask how the brain works
Scientists have used the 'mirror box' illusion -- an old magic trick - in a number of neuroscience studies. Researchers are using a new version of the illusion to study how the brain processes multiple sensory inputs to perceive our bodies and the world around us.
No simple way of predicting breathing difficulties in pugs, French bulldogs and bulldogs from external features
As many as a half of all short-nosed dogs such as pugs, French bulldogs and bulldogs experience breathing difficulties related to their facial structure. However, research suggests that there is no way to accurately predict from visible features whether an apparently healthy pug or French bulldog will go on to develop breathing difficulties.
Dietary restriction can improve learning in worms
Dietary restriction -- the reduction of a specific nutrient or total dietary intake without triggering malnutrition -- increases longevity and improves learning, but are these processes regulated separately? A new study indicates that the answer is 'yes.'
