Stream Computing Provides Real-Time Analysis For New Insight into Effects on Earth BERLIN, June 3 /PRNewswire-FirstCall/ -- IBM INFORMATION ON DEMAND CONFERENCE -- IBM (NYSE: IBM) and Uppsala University and the Swedish Institute of Space Physics announced today a major new Stream Computing project to analyze massive volumes of information in real time to better understand "space weather". By using IBM InfoSphere Streams to analyze data from sensors that track high frequency radio waves,...

In-growth and new generation of blood vessels, which must take place if a wound is to heal or a tumor is to grow, have been thought to occur through a branching and further growth of a vessel against a chemical gradient of growth factors. Now a research team at Uppsala University and its University Hospital has shown that mechanical forces are considerably more important than was previously thought. The findings, published today in the journal Nature Medicine, open up a new field for...

UPPSALA, Sweden, May 25 /PRNewswire/ -- Beactica AB, the Swedish fragment-based drug discovery company, today announced that it has entered into an agreement with Cubist Pharmaceuticals, Inc. (Lexington, MA; NASDAQ: CBST). Under the agreement, Beactica will use its Sprint(TM) surface plasmon resonance (SPR)-integrated drug discovery platform to target multi-component proteins from pathogenic bacteria of interest to Cubist. Financial terms of the agreement were not disclosed. "We are...

Inhibiting the "drug efflux pumps" in bacteria, which function as their defence mechanisms against antibiotics, can mask the effect of mutations that have led to resistance in the form of low-affinity drug binding to target molecules in the cell. This is shown by researchers at Uppsala University in a new study that can provide clues to how the development of resistance to antibiotics in bacteria can be delayed.The introduction of antibiotics as drugs in the treatment of bacterial infections...

The fossil record usually shows what adult animals looked like. But the appearance and lifestyle of juvenile animals often differ dramatically from those of the adults. A classic example is provided by frogs and salamanders. New discoveries from Uppsala, Cambridge and Duke Universities, published in Science, show that some of the earliest backboned land animals also underwent such changes of lifestyle as they grew up. Professor Per Ahlberg at the Department of Physiology and Developmental...

An international research team, including Professor Rajeev Ahuja's research group at Uppsala University, has shown that small additions of potassium drastically improve the hydrogen-storage properties of certain types of hydrogen compounds. The findings are published in the Web edition of Angewandte Chemie International Edition."Our energy-consuming world has become more and more dependent on new methods of storing and converting energy for new, environmentally friendly means of...

Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. The findings, published in PNAS, reveal extremely high frequencies of gene exchange within this group of bacteria. In the future it is hoped that it will be possible to use sex-manipulating bacteria as environmentally friendly pesticides against harmful...

Researchers at Uppsala University, together with colleagues at the Karolinska Institute and the Sanger Institute, have now found all the genes the determine the dosage of the blood-thinning drug warfarin. The findings are published in the scientific journal PLoS Genetics. "We have previously studied selected genes that can affect warfarin treatment. Now that we have gone in and scanned the entire genome, we see that the two most important genes are among those we previously singled out," says...

Hurdia victoria was originally described in 1912 as a crustacean-like animal. Now, researchers from Uppsala University and colleagues reveal it to be just one part of a complex and remarkable new animal that has an important story to tell about the origin of the largest group of living animals, the arthropods. The findings are being published in this week's issue of Science. The fossil fragments puzzled together come from the famous 505 million year old Burgess Shale, a UNESCO World Heritage...

Researchers at Uppsala University and Harvard University have collaboratively developed a new theoretical model to explain how proteins can rapidly find specific DNA sequences, even though there are many obstacles in the way on the chromosomes. The findings are being published today in the scientific journal Nature Physics. In living cells, DNA-binding proteins regulate the activity of various genes so that different cells carry out the right tasks at the right time. For this to work, the...
