Controversies over new airport runways make locals more noise-sensitive.
Public controversy surrounding the impending building of a runway may make locals much more sensitive to increased aircraft noise than planners predict. A new study warns that it could be easy to underestimate the impact of changes such as those proposed for Britains Heathrow Airport.
A new runway began operating at Vancouver International Airport in 1996 after highly publicized local objection to
Female embryos exert a greater influence than male embryos over the hormone that nurtures early pregnancy, and the difference can be detected as little as 16 days after conception, according to new research published (Wednesday 30 January) in Europe’s leading reproductive medicine journal Human Reproduction.*
Israeli scientists have demonstrated that levels of maternal serum HCG (MSHCG) – the hormone that reveals in blood or urine tests whether or not a woman is pregnant – are nearly a fifth
A quantum afterburner extracts laser light from vehicle exhaust.
The hot gases belching out of your cars exhaust are not just useless waste. They are a laser waiting to happen, says physicist Marlan Scully1.
All you need to harness this potential, suggests Scully, of Texas A&M University in College Station, is a quantum afterburner. This hypothetical modification would use quantum mechanics to boost the engines efficiency by clawing back waste heat and turning it
Many of today’s medicines were discovered by trial and error: a substance is found which helps alleviate the symptoms of a disease, and it may take years before scientists really understand how it works. Typically they find that a drug has its effects by attaching itself to a particular molecule in a cell and blocking part of its activity, the way you might prevent someone from turning a light on or off by putting a lock over the switch. Scientists now hope to take the opposite approach, and custom-d
Sensors and loudspeakers reduce in-car racket.
Tired of shouting to your passenger as you drive, striving to make your voice heard over the rumble of the car? Help is on the way, in the form of strategically placed sensors and loudspeakers.
Researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Taejon have developed a prototype system that shaves up to 6 decibels off the typical motoring noise of around 60 decibels. Thats more than any other co
The delicate balance of life and death in Africa is nowhere more evident than on the banks of the continent`s mighty rivers. Rural communities depend on the rich silt brought down by rivers for farming but they are also at risk of devastating floods, as are urban dwellers in informal settlements that are often built on floodplains.
Dr Sue Marriott, reader in earth sciences at UWE`s Faculty of the Built Environment, is setting off this month to help with training environmental managers in fl
