Transmission of tuberculosis is linked to historical patterns of human migration
In this study, a team of scientists led by Dr. Igor Mokrousov from St. Petersburg's Pasteur Institute demonstrated that the evolutionary history of the causative agent of tuberculosis (TB) has been shaped by human migration patterns. view more (2005-09-27)
Viruses can jump between primates and humans, researchers warn
Viruses that jump the species barrier between monkeys and humans can harm both people and animals, and we should take steps to reduce the risk of virus transmission. view more (2006-08-24)
Study confirms limited human-to-human spread of avian-flu virus in Indonesia in 2006
In the first systematic, statistical analysis of its kind, infectious-disease-modeling experts at Fred Hutchinson Cancer Research Center confirm that the avian influenza A (H5N1) virus in 2006 spread between a small number of people within a family in Indonesia. view more (2007-08-29)
Many parents at-risk for cancer disclose genetic test results to children
Predictive genetic testing for adult-onset diseases, including cancer, is generally discouraged until the age at which interventions are believed to be helpful. view more (2007-08-20)
Envisat breaks the terabyte barrier
Only three months after the launch of ESA's Envisat spacecraft, the largest and most capable satellite ever built to monitor the Earth's environment, the Envisat system recently passed one of its most significant milestones to date. Last Sunday, 23 June 2002, the Envisat system for distributing satellite imagery reached the terabyte mark of data... view more... (2002-06-26)
Scientists from Scotland to Sweden Arrive at NIMBioS to Study Bovine TB
In 2008, the U.S. Department of Agriculture spent $31 million to depopulate herds of cattle affected by bovine tuberculosis (TB), even though the risk of the disease has been significantly reduced in the U.S. over the past several decades. view more (2009-07-13)
GENE TRANSFER FROM GENETICALLY MODIFIED CROPS
The report, which is based on a desk study of a substantial quantity of previously published research in related areas, considers all the routes by which the mixing of organic and genetically modified crops may occur, including pollen transfer and the growth of volunteers. It concludes that no system for the field production of seed can guarantee... view more... (1999-06-17)
Chips for future multimedia radio systems
Millions of people surf the Internet, and their number is constantly increasing. But users regularly have to contend with bottlenecks when trying to access the net, or long periods of waiting while downloading sophisticated multimedia applications, such as video sequences for home learning. Radio systems provide a way to avoid the "traffic jam".... view more... (1999-09-03)
How mosquitoes could teach us a trick in the fight against malaria
The means by which most deadly malaria parasites are detected and killed by the mosquitoes that carry them is revealed for the first time in research published today (5 March) in Science Express. The discovery could help researchers find a way to block transmission of the disease from mosquitoes to humans. view more (2009-03-06)
HIV study prompts call for revision of breastfeeding guidelines
A study by scientists at the Africa Centre for Health and Population Studies, South Africa, has shown that exclusive breastfeeding can significantly reduce the risk of HIV transmission from mother to child in infants aged under six months when compared to those also given solid foods or replacement feed (i.e. formula milk). view more (2007-03-30)
Human genetic databases - Publication of evidence
The House of Lords Science and Technology Committee has today published the written evidence received in its new Inquiry into Human Genetic Databases. Lord Oxburgh, who chairs the Sub-Committee undertaking the Inquiry, said: "This is a unique and invaluable description of current activities in human genetic databases, mainly in the words of... view more...

Ecological replacement of native red squirrels by invasive greys driven by disease
The traditional explanation for the replacement of the native red squirrel by the introduced grey over much of the United Kingdom is that the grey out-competes the red for food resources. A new study published in the March issue of Ecology Letters demonstrates that a virus introduced with the grey may also be a crucial component. The research team... view more... (2003-03-11)
ROYAL SOCIETY MEDAL FOR REVOLUTIONARY GENETIC RESEARCH AT THE JOHN INNES CENTRE
The research group headed by Professor Gale and Dr Moore was the first to produce a map which described in detail the organisation of the genetic information in wheat. They were surprised to find that modern-day bread-wheat and its ancient ancestors, although separated by about a million years of evolution, had remained almost identical in terms... view more...

Dairy Farming, Cattle Milk Genes And Gene-Culture Co-Evolution
Cattle milk genes, the genetic capacity of humans to digest milk and the habit of using dairy products have evolved together in a unique process called gene-culture co-evolution says a team of researchers in the last issue of the journal Nature Genetics. Genes are for most species the only way to transfer information across generations but in some... view more... (2003-12-18)
A genetic link to premature ejaculation
Premature ejaculation can be embarrassing, but a new study suggests that it might be a genetic disorder. view more (2009-05-28)
New quantum key system combines speed, distance
Researchers at the National Institute of Standards and Technology (NIST) have built a prototype high-speed quantum key distribution (QKD) system, based on a new detector system that achieves dramatically lower noise levels than similar systems. view more (2007-06-11)
Why results from genetic tests should be available to medical insurance companies (P 395)
Authors of a Viewpoint article in this week's issue of THE LANCET discuss the ethical considerations surrounding genetic test results and disclosure to medical insurance companies-the authors outline their reasons for supporting the disclosure of such test results to make health insurance more equitable. Nick Raithatha and Richard D Smith from... view more... (2004-01-28)
Hopkins joins Ugandan researchers to study pediatric AIDS vaccine
Scientists at Makerere University, in Kampala, Uganda, along with scientists from Johns Hopkins and other institutions worldwide, have begun the first clinical safety trial in Africa of a vaccine to prevent mother-to-child transmission of HIV through breastfeeding. view more (2006-10-13)
Couples attending counseling sessions together better prepared to ease children's concerns
When women with children attend a counseling session before undergoing genetic testing for breast cancer, they are far more likely than their partners to be up front with their kids about the tests and the potential for cancers being inherited, according to a study released today here at the annual meeting of the National Society of Genetic... view more...

AFRICAN HIV-1 EPIDEMIC NOT CAUSED BY MORE INFECTIOUS VIRAL SUBTYPE (p 1149)
The explosive HIV-1 epidemic in sub-Saharan Africa is unlikely to be the result of a viral subtype with increased infectivity, according to the results of a study published in this week’s issue of THE LANCET. The HIV-1 epidemic in eastern and southern sub-Saharan Africa is mainly caused by HIV-1 subtypes A, C, and D, whereas those in the USA... view more... (2001-04-11)
