The pressure on the environment of building during the past 5000 years can be observed clearly from the air. In a recent lecture at the Society of Chemical Industry (SCI), aerial photographer and concrete specialist Christopher Stanley illustrated the evolution of construction and its lasting impact, from stone circles to skyscrapers.

Stanley’s lecture ‘Managing the environment: a perspective from land, air and sea’ followed the presentation of the 2002 SCI Environment Medal in recognition o

Major new research examining the use of virtual surgery could revolutionise the way surgeons are trained in the future.

Experts use to believe that virtual reality, which allows trainee surgeons to feel and see exactly what they would if they were in the operating theatre, may help improve surgical skills, but it hadn’t been proved – until now.

The innovative research, by world experts from Yale University and Queen’s University Belfast, has shown that surgeons who trained o

An international team of researchers leaded by the Universitat Autònoma de Barcelona have found experimental evidence that the various manifestations of fear in animals are influenced by a specific place or region within the genome. The results, published in the latest edition of Genome Research, were obtained with rats, but the scientists suspect that this research will facilitate an understanding of genetic characteristics and conditioning factors related to fear in humans.

Findings from the Anthrax Vaccine Expert Committee (AVEC) do not suggest a high frequency of medically important adverse events associated with anthrax vaccination

Between March 1998 and March 2002 525,000 US military personnel were vaccinated against anthrax. In the case of an outbreak, this vaccine could be extended to civilians, as occurred in December 2001. The Anthrax Vaccine Expert Committee (AVEC), a civilian panel of physicians and scientists set up to monitor the safety of vaccinati

Biotech human breast milk growing but not bottled.

Genetically modified (GM) rice carrying a protein from human breast milk could be used to enhance infant formula, researchers hope. But at present, the protein would not gain approval for use in the United States.

Nutritionists agree that breast milk is best for a baby; infant formula is not as nourishing as the real thing. So for mothers unable to breast-feed, the biotech industry is engineering crops or animals to make huma

Cosmologists claim Universe has been forming and reforming for eternity.

The Universe was not born in one Big Bang, it has been going through cycles of creation and annihilation for eternity, according to a controversial new mathematical model 1 .

It’s a compelling claim. The new cyclic model removes a major stumbling block common to existing theories of the Universe – namely, that physics can’t explain what came before the Big Bang.
