Signatures of the first stars

15 April, 2005 - Uppsala universitet

A primitive star with extremely low iron content has been discovered by an international research team from Sweden, Japan, Germany, USA, Australia and Great Britain. This indicates the original composition of the gas from which the star formed had low iron content. The results are published in Nature online this week.

Lund University part of EU project on global land destruction

14 April, 2005 - Lunds universitet

The EU is now entering an agreement with Lund University regarding research into the desertification. The background is that 40 research organizations from 16 countries recently gathered in Madrid to launch an EU project (DeSurvey) about land degradation and desertification in Europe, Africa, Asia, and South America. The EU funding is about SEK 75 million. Lund University will be taking part as the only Scandinavian unit, in the person of Professor Ulf Helldén at the Department of Physical Geography and Ecosystem Analysis and the Center for GeoBiosphere Science.

High-powered living DNA cannon

13 April, 2005 - Lunds universitet

We all know that a viral infection can developed extremely
quickly, but in fact it’s even more dramatic than that – the process is literally explosive. The pressure inside a virus is 40 atmospheres, and it is just waiting for an opportunity to blow up. The virus is like a living DNA cannon, and just how this cannon functions has been mapped by Dr. Alx Evilevitch at the Department of Biochemistry at Lund University. This is knowledge that will have applications in gene therapy, drug development, nanotechnology and the treatment of infections.

Cyanobacteria (“blue-green algae”) produce toxin with possible connection to neurodegerative disorders

8 April, 2005 - Stockholms universitet

It is well known that a tiny number of cyanobacteria, previously known as blue-green algae, produce substances that can be toxic to both humans and animals. Now a research team from Sweden, Scotland, and the U.S. has found that a further toxin (BMAA, -methyl amino-alanine) with a possible connection to degenerative nerve diseases like ALS, Alzheimer’s, and Parkinson’s is produced by cyanobacteria that are widespread around the world.

Experts Warn Ecosystem Changes Will Continue to Worsen, Putting Global Development Goals At Risk

31 March, 2005 - Stockholms universitet

A landmark study recently released reveals that approximately 60 percent of the ecosystem services that support life on Earth – such as fresh water, capture fisheries, air and water regulation, and the regulation of regional climate, natural hazards and pests – are being degraded or used unsustainably. Scientists warn that the harmful consequences of this degradation could grow significantly worse in the next 50 years.

Karlstad University invests in a large experimental freshwater aquarium facility

24 March, 2005 - Karlstads universitet

An experimental freshwater aquarium facility for research and teaching has been built at Karlstad University. The 250 m2 facility consists of five
rooms, equipped with several independent aquarium systems to create stream and lake-like environments. The four large, seven-meter long artificial streams are unique for Sweden, with few equivalents in the rest of the world.

Current measurement by counting of each electron. A new way to measure current

17 March, 2005 - Chalmers tekniska högskola

For the first time in the world, researchers at the Quantum Device Physics Laboratory of the Department of Microtechnology and Nanoscience at Chalmers University of Technology in Göteborg, Sweden, have been able to measure a current by counting the single electrons that pass through a nanoelectronic circuit. This is a fundamentally new way of measuring electrical currents, and may find its application in measurements of extremely small currents with very good accuracy. The results are published in the scientific journal Nature.

Domesticated pig’s wild origin mapped

11 March, 2005 - Uppsala universitet

Scientists at Uppsala University and the Swedish University for Agricultural Sciences have been participating in an international collaborative project to map the wild origins of the domesticated pig. The findings show that the wild boar was domesticated several times in different parts of Europe and Asia. The study is being presented in tomorrow’s issue of the scientific journal Science.

Uppsala leads new european network on artificial photosythesis

21 February, 2005 - Uppsala universitet

Nature utilizes energy from the sun for its production. Some algae produce hydrogen from water with the help of solar energy. So why not imitate nature to extract renewable energy without harming the environment? The EU is giving European research a boost by allocating €1.8 million to a new network to be led by Uppsala University.

Storm-damaged forests mapped by military radar technology

10 February, 2005 - FOI Totalförsvarets forskningsinstitut

In January 2005, FOI (Swedish Defense Research Agency) and Ericsson Microwave Systems mapped storm-damaged areas in southern Sweden using military airborne radar technology mounted in a test aircraft operated by FMV
(Swedish Defense Materiel Agency). The trial shows that the technology can cover large land areas as well as identify individual trees including those damaged by winds.
