Cell Transplantation
Cell Transplantation reports islet cell advancement increases impact on transplantation
Transplanted islet cells are challenged by hypoxic conditions and host immune reactions. When smaller islets were grouped into clusters (ICCs) they were found to be less susceptible to immune reaction, ischemia and oxygen starvation. The new process increased glucose sensitivity and modifying the ICC surface with a poly-lipid helped prevent immune reactions. The work helps to overcome shortages of islet cells, reduces the need for immunosuppressant regimes, and may improve pancreatic islet transplantation.

Flu outbreaks predicted with weather forecast techniques
Scientists have developed a new system that adapts techniques used in weather prediction to generate local forecasts of seasonal influenza outbreaks. By predicting the timing and severity of the outbreaks as far as seven weeks in advance, the system can eventually help society better prepare for them.

Do missing Jupiters mean massive comet belts?
Using ESA's Herschel space observatory, astronomers have discovered vast comet belts surrounding two nearby planetary systems known to host only Earth-to-Neptune-mass worlds. The comet reservoirs could have delivered life-giving oceans to the innermost planets.

Researcher studies 'middle ground' of sea-level change
The effects of storm surge and sea-level rise have become topics of everyday conversation in the days and weeks following Hurricane Sandy's catastrophic landfall along the mid-Atlantic coast. Research at the Virginia Institute of Marine Science is throwing light on another, less-familiar component of sea-level variability -- the "intra-seasonal" changes that occupy the middle ground between rapid, storm-related surges in sea level and the long-term increase in sea level due to global climate change.

Comparative Cytogenetics
From Mediterranean coasts to Tatra Mountains and beyond: Plant chromosome number variation
It is well known that plants show huge variation in chromosome numbers, mainly because of multiple genome copies. One of the most intriguing issues in botany is to clarify the geographical pattern linked to this variation. In the research, the hypothesis that mean chromosome number in vascular plants increases at increasing latitude was tested. The study was published in the open access journal Comparative Cytogenetics.

A rather thin and long new snake crawls out of one of Earth's biodiversity hotspots
A team of Ecuadorian and American scientists have discovered a new species, belonging to a neotropical group of remarkably long arboreal (tree-dwelling) snakes: the blunt-headed vine snakes, from the Choco biodiversity hotspot in northwestern Ecuador. DNA data suggest that the closest relative of the new species lives on the other side of the Andes. The study was published in the open access journal ZooKeys.

Projected sea-level rise may be underestimated
The rate of sea-level rise in the past decades is greater than projected by the latest assessments of the IPCC, while global temperature increases in good agreement with its best estimates. This is shown by a study now published in the journal Environmental Research Letters. Stefan Rahmstorf from the Potsdam Institute for Climate Impact Research and his colleagues compare climate projections to actual observations from 1990 up to 2011.

New method for diagnosing malaria
Danish researchers have developed a new and sensitive method that makes it possible to diagnose malaria from a single drop of blood or saliva. The method might eventually be used in low-resource areas without the need for specially trained personnel, expensive equipment, clean water or electricity. With the development of this method, the researchers hope to go one step further in identifying and treating all patients suffering from malaria.

Enzyme explains angina in diabetics
In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital in Sweden show that an enzyme called arginase might have a key part to play in the development of cardiovascular disease in patients who already have type II diabetes. According to the team, arginase prevents the formation of protective nitrogen oxide in the blood vessels, and treatments that inhibit this enzyme reduce the risk of angina in diabetics.

Tracking down smallest biomarkers
A new device is to provide the metrological basis for promising biomarkers. The vacuum-compatible version of the Pilatus hybrid pixel detector for X-rays, which was developed by Dectris in cooperation with the Physikalisch-Technische Bundesanstalt, allows the size of nano-particles -- which, to date, have been difficult to characterize -- to be determined using small-angle X-ray scattering at low photon energies.
