Resurfacing urban areas to offset 150 billion tonnes of CO2
Imagine a world where the rooftops and pavements of every urban area are resurfaced to increase the reflection of the Sun’s light rays. Well, this is exactly what a group of Canadian researchers have done in an attempt to measure the potential effects against global warming. In a study published today in IOP Publishing’s journal [...]
Researchers assess radiation exposure in obese patients
A group of US researchers has quantified the amount of radiation obese patients receive when undergoing routine medical scans. Results published today by IOP Publishing in the journal Physics in Medicine & Biology, have shown that, when undergoing a CT scan, a forced change of operation parameters for obese patients results in an increase of [...]
Handheld plasma flashlight rids skin of notorious pathogens
A group of Chinese and Australian scientists have developed a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant. The device could be used in ambulance emergency calls, natural disaster sites, military combat operations and many other instances where treatment is required in remote locations. The plasma flashlight, presented today in [...]
The role of physics in the sinking of the Titanic
A century on from the sinking of the Titanic, in April’s Physics World science writer Richard Corfield takes a look at the cascade of events that led to the demise of the ‘unsinkable’ ship, taking into account the maths and physics that played a significant part. At 11.40 p.m. on Sunday 14 April 1912 [...]
Fusion presents low proliferation risk, experts conclude
American researchers have shown that prospective magnetic fusion power systems would pose a much lower risk of being used for the production of weapon-usable materials than nuclear fission reactors and their associated fuel cycle. The researchers, from Princeton University, found that if nuclear fusion power plants are designed to accommodate appropriate safeguards, there is little [...]
