The earth's most successful bacteria are found in the oceans and belong to the group SAR11. In a new study, researchers from Uppsala University provide an explanation for their success and at the same time call into question generally accepted theories about these bacteria. In their analysis they have also identified a rare and hitherto unknown relative of mitochondria, the power stations inside cells. The findings were published in two articles in the journals Molecular Biology and...

"Our data indicate that the brain becomes hypersensitive to rewards when this co-signaling of glutamate and dopamine does not function. Lower doses than normal are enough to increase the propensity to ingest the substance, and this is true of both sugar and cocaine," says Ã…sa Mackenzie, associate professor of neuroscience at Uppsala University and the researcher who led the study. Addiction disorders are a major social problem, and we lack sufficient knowledge of how they...

Our understanding of what differentiates cancer cells from normal cells is limited by a lack of methods for studying the complex signal systems of individual cells. By combing two different methods, a team of Uppsala researchers have now provided the research world with a tool for studying signal paths on several levels at the same time. Their article is being published today in PLoS One. "We also show that the method can be used to determine the molecular effect of drugs or pharmaceuticals,"...

A new, promising marker for diagnosing prostate cancer has been discovered by Uppsala researchers with the aid of a unique method developed at the Department of Immunology, Genetics and Pathology. The study, being published this week in the journal Proceedings of the National Academy of Sciences, PNAS, can lead to more reliable diagnoses and fewer unnecessary operations. The PSA marker used for diagnosing prostate cancer today has been criticized for false positive responses, leading to...

A Swedish research team partly consisting of researchers from Uppsala University followed a group of prostate cancer patients in the Nordic region for 15 years. The study found, among other things, that surgery reduces the risk that men with prostate cancer (even those with low-risk tumours) will die within 15 years. The results were published today in the New England Journal of Medicine. The researchers followed Swedish, Finnish and Icelandic prostate cancer patients. Radical prostatectomy...

UPPSALA, Sweden, April 27, 2011 /PRNewswire/ -- Beactica, the leading Swedish fragment-based drug discovery company, today announced that it has entered into an agreement with Janssen Research & Development, a division of Janssen Pharmaceutica NV. Under the agreement, Beactica will use its proprietary drug discovery platform, Sprint(TM), to generate small-molecule lead compounds against undisclosed targets of therapeutic interest to Janssen. Financial terms of the agreement were not...

Frogs appear to be very sensitive to progestogens, a kind of pharmaceutical that is released into the environment. Female tadpoles that swim in water containing a specific progestogen, levonorgestrel, are subject to abnormal ovarian and oviduct development, resulting in adult sterility. This is shown by a new study conducted at Uppsala University and published today in the scientific journal Aquatic Toxicology. Many of the medicines that people consume are released into the environment via...

Developing new drugs is a highly costly and time-consuming process. Of 20 candidates, 19 are normally rejected because they don't work or have unwanted side effects. Now a research team led by Professor Lars Baltzer at Uppsala University has produced a tiny molecular "binder" that has the potential to change this landscape radically. The study, published today in the prestigious journal Angewandte Chemie, presents the concept of a tiny polypeptide consisting of 42 amino acids to which...

Superficial contacts on Facebook, apparently unnecessary comments, and banal status updates may be more worthwhile than we think. This is shown in a new report from the National IT User Center. The report also predicts the new social media will ultimately lead to more individual entrepreneurs. Many people are critical of those who collect hundreds of so-called friends on Facebook. Often the majority of these "friends" are old classmates, acquaintances of acquaintances, and the like,...
