New malaria enzyme laid bare with help of computer calculations

7 December, 2004 - Uppsala universitet

Using only computers, a research team at Uppsala University in Sweden has managed to reveal both the structure and the function of a newly discovered enzyme from the most dangerous malaria parasite, Plasmodium falciparum. All that was needed was the amino acid sequence of the enzyme. The findings may represent a breakthrough for future pharmaceutical research.

Magnetism do not cause paranormal experiences

6 December, 2004 - Uppsala universitet

Previous research has shown that paranormal experiences can be achieved via electromagnetic stimulation of the temple lobe. Now scientists from Uppsala and Lund universities are calling into question how the experiments were set up and therefore questioning the results. Their study involving identical magnetic field equipment produced no such relationship.

Good results with only one egg in in-vitro fertilization

2 December, 2004 - Göteborgs universitet

Nearly as many women who received only one embryo at a time gave birth as women who received two embryos. At the same time the risk of giving birth to twins is minimized. These are the findings of a major study from the Sahlgrenska Academy, at Göteborg University in Sweden.

The logic of life brings order to our genes

30 November, 2004 - Lunds universitet

It is tricky enough to get a soccer team of eleven players to cooperate and work as one – but what would it be like if there were 25,000 players on the field? What would the rules be like, and how many referees would it take to make sure that the rules were followed? As it happens, our genomes consist of networks of roughly 25,000 interacting genes, and these networks are obviously very stable and resilient to changed conditions. Out of billions of cells, not a single one falls into chaos. How can order be maintained? A question that scientists have been pondering since the 1960s may now have been answered by theoretical physicists at Lund University.

Europe’s New Role in the World: An Ethical Power

25 November, 2004 - Stockholms universitet

The question about a common European foreign policy is high on the political agenda. Two recent international events – the agreement on a European Constitution and the war in Iraq – have put the spotlight on the prospects for a common European foreign policy. In a comparative foreign policy study of the three largest EU member states – Britain, France and Germany – Lisbeth Aggestam at Stockholm University analyses how political elites in these three countries conceive of a European foreign policy after the end of the Cold War.

Testosterone improves women’s sex lives

22 November, 2004 - Karolinska Institutet

A recently published dissertation from the Karolinska Institutet in Sweden shows that testosterone has both a physiological and a psychological impact on women’s sexuality.

Hunting for development in Mugabe’s Zimbabwe

19 November, 2004 - Göteborgs universitet

In the West it is more common to question how much longer wildlife will be able to survive in Africa than how a poor local populace will be able to survive amidst this wildlife. A dissertation at Göteborg University in Sweden investigates how the developmental program CAMPFIRE, “Communal Areas Management for Indigenous Resources,” was introduced among the local inhabitants of Sotho, Venda, and Ndebele in Gwanda District in southern Zimbabwe with the aim of creating sustainable exploitation of wildlife and combating poverty.

Swedish researchers describe new structure for kidney filter: the slit diaphragm

17 November, 2004 - Karolinska Institutet

One of the main functions of the kidney is the formation of urine by filtration of the plasma. The size-selective kidney filter, known as the slit diaphragm (SD), prevents plasma proteins from leaking into the urine. This filtration barrier consists of layers of specialized cells, including podocytes, which are connected by the interdigitating zipper-like structure of the SD, and defects in the SD are associated with a number of kidney diseases. In 1974, the zipper-like SD structure was first described, however this model was later questioned and the molecular nature of the SD has since remained obscure.
