Með þátttöku íslenska skólakerfisins í alþjóðlegum samanburðarrannsóknum (TIMSS, PISA o.fl.) hefur náttúruvísindamenntun ótvírætt hlotið vaxandi athygli. Jafnframt hefur hugmyndinni um „náttúruvísindamenntun fyrir alla“ vaxið fiskur um hrygg. Meginmarkmið ...

Developing geothermal power projects may lead to trade-offs, whereby the economic and social benefits of the venture are difficult to compare with its cultural consequences, which include impacts to ES such as aesthetics, spiritual enrichment and ...

Background: About 70% of teachers who instruct healthcare students are considered sessional (adjunct/temporary part-time) faculty and receive limited instruction in pedagogy. Sessional faculty may feel isolated and struggle with their teacher identity, ...

The topical administration route is commonly used for targeting therapeutics to the eye; however, improving the bioavailability of drugs applied directly to the eye remains a challenge. Different strategies have been studied to address this challenge. ...

Background Data on the haematological outcomes of patients who continue clozapine treatment following neutropenia are very rare as even mild neutropenia results in mandatory discontinuation of clozapine in most countries. However, in Iceland where ...

A new lava field was formed at Holuhraun in the Icelandic Highlands, north of Vatnajökull glacier, in 2014–2015. It was the largest effusive eruption in Iceland for 230 years, with an estimated lava bulk volume of ~1.44 km3 covering an area of ~84 km2. ...

Non-covalent and site-directed spin labeling gives easy access to spin-labeled nucleic acids for the study of their structure and dynamics by electron paramagnetic resonance (EPR) spectroscopy. In a search for improved spin labels for non-covalent ...

The prevalence and consequences of nasal obstruction in untreated obstructive sleep apnea patients are not known. The study objectives were to investigate the frequency of subjective and objective nasal obstruction in untreated sleep apnea patients and ...

An isoindoline-nitroxide derivative of guanine (G, "G-spin") was shown to bind specifically and effectively to abasic sites in duplex RNAs. Distance measurements on a G-labeled duplex RNA with PELDOR (DEER) showed a strong orientation dependence. Thus, ...

Studying nucleic acids often requires labeling. Many labeling approaches require covalent bonds between the nucleic acid and the label, which complicates experimental procedures. Noncovalent labeling avoids the need for highly specific reagents and ...
