In the animal kingdom colourful traits can be both a blessing and a curse. A new study from a group of researchers at Uppsala University has studied the conspicuous wing coloration of two species of damselflies. Their results imply that males, but not females, pay a high cost when using colour to communicate with other damselflies, both in terms of predation risk and visibility to prey.
A group at Uppsala University has investigated how levels of endocannabinoids – which target the same receptors as cannabis – are affected by short sleep duration, and whether acute exercise can modulate this effect.
Researchers at Uppsala University have used computer modelling to study how brain tumours arise. The study, which is published today in the journal EBioMedicine, illustrated how researchers in the future will be able to use large-scale data to find new disease mechanisms and identify new treatment targets.
Both heredity and environmental factors influence our risk of cardiovascular disease. A new study, by researches at Uppsala University, shows now that the memory of a heart attack can be stored in our genes through epigenetic changes. The results have been published in the journal Human Molecular Genetics.
Uppsala University has received its first donation for sociology to be used for the Hans L. Zetterberg Prize “to be awarded yearly to a younger researcher, Swedish or foreign, who, with his/her scientific work in sociology, preferably through fruitful combination of theory and practice, has moved the research front forward.”
A report has been released for the upcoming Uppsala Health Summit on ending childhood obesity, outlining the challenges, including the effectiveness of the much debated sugar-tax, how to target interventions for immigrants and the role of industry. The report is produced to prepare the 200 delegates for discussions on concrete solutions.
This week in Nature, an international team of researchers shows that fossils of the 360 million-year-old tetrapod Acanthostega, one of the iconic transitional forms between fishes and land animals, are not grown-ups but all juveniles. This conclusion sheds new light on the life cycle of Acanthostega and the so-called conquest of land by tetrapods.
A research team at Uppsala University has determined the complete genetic code of 11 members of a flycatcher pedigree. Doing this, they have for the first time been able to estimate the rate of new mutations in birds. When they combined the new results with mutation rate estimates from other organisms, a clear pattern emerged: The more common a species is, the lower its mutation rate.
The amount of time a blood sample used for medical research has been stored at a biobank may affect the test results as much as the blood sample provider’s age. These are the findings of a new study from Uppsala University, published in journal EBioMedicine. Until now, medical research has taken into account age, sex and health factors, but it turns out that storage time is just as important.
Heparan sulphate occurs as carbohydrate chains which are very important for human body cells both for normal foetal development and during the course of various diseases. All new molecular knowledge concerning these chains is therefore important. Researchers can now show that the same enzyme which determines the charge pattern of the chains also determines their length.
Cell lines are cultured cells that are commonly used in medical research. New results from Uppsala University show that such cells are not always what they are assumed to be. Using genetic analyses, the researchers showed that a commonly used cell line which was established in Uppsala almost fifty years ago does not originate from the patient it is claimed to stem from.
Being able to determine magnetic properties of materials with sub-nanometer precision would greatly simplify development of magnetic nano-structures for future spintronic devices. In a new study Uppsala physicists make a big step towards this goal - they propose and demonstrate a new measurement method capable to detect magnetism from areas as small as 0.5 nm2.
Many people suffer from anxiety and fears, and a common treatment for these problems is exposure therapy. In a new study published in Current Biology, researchers at Uppsala University have shown how the effect of exposure therapy can be improved by disrupting the recreation of fear-memories in people with arachnophobia.
Research has shown that the growth of cancerous tumours is affected by the transforming growth factor beta (TGF-beta) in the body’s cells; TGF-beta both suppresses and stimulates tumour development, but it has not been understood how this happens. A new study published in the journal Science Signaling today reveals important details behind this process.
Climate researcher Kevin Anderson will be Uppsala University’s second holder of the Zennström visiting professorship in Climate Change Leadership. He will continue the work of Doreen Stabinsky in establishing an environment that will be unique, both in Sweden and in the world.
In a study from Uppsala University, published in the American journal JAMA Cardiology, the fatty acid linoleic acid (Omega 6) in subcutaneous adipose tissue was linked to lower mortality among older men followed over a 15-year period.
The use of smartphones and tablet computers during evening hours has previously been associated with sleep disturbances in humans. A new study from Uppsala University now shows that daytime light exposure may be a promising means to combat sleep disturbances associated with evening use of electronic devices. The findings are published in the scientific journal Sleep Medicine.
For the first time, researchers have revealed the nanostructure of the mesoporous magnesium carbonate Upsalite® and pore size control was achieved without organic templates or swelling agents. By controlling the pore structure of the material the amorphous phase stabilisation exerted on poorly soluble drug compounds can be tuned and the drug delivery rate can be tailored.
In a new study researchers from Sweden and Italy show what happens when magma meets limestone on its way up to the surface. Magma-limestone interaction might help explain why volcanoes like Vesuvius in Italy and Merapi in Indonesia are particularly explosive and, moreover, it helps us to understand another source of natural carbon released to the atmosphere by volcanoes.
Treatments for social anxiety disorder often include either selective serotonin reuptake inhibitors (SSRIs) or cognitive behavioural therapy (CBT), but new research from Uppsala University indicates that social anxiety disorder is best treated with the combination of SSRI and CBT, which also improves emotion processing in the brain. The results are published in the British Journal of Psychiatry.
