Bacterial infection stresses hematopoietic stem cells
It is becoming clear that immune cells are not the only cells that react to bacterial infection. Researchers from Japan and Switzerland found that bacterial infection also activates hematopoietic stem cells resident in the bone marrow far from the site of infection. This infection significantly reduces the ability of the stem cells to produce blood by forcing them to proliferate. These findings suggest that bacterial infection may lead to a cause of anemia or leukemia.

Journal of Applied Remote Sensing honors 3 as best papers
Best Paper awards have been announced for three articles in the Journal of Applied Remote Sensing, published by SPIE, the international society for optics and photonics. Papers report on technology for ice cloud measurement derived from CALIPSO mission data, a neural network architecture for high spatial resolution remote-sensing image scene classification, and a radar sensor designed to detect and image moving objects behind a wall.

Data mining finds more than expected beneath Andean Plateau
Seismologists investigating how Earth forms new continental crust have compiled more than 20 years of seismic data from a wide swath of South America's Andean Plateau and determined that processes there have produced far more continental rock than previously believed.

An eye towards islets
The National Science Foundation has funded a multi-university study led by researchers at the University of Pittsburgh Swanson School of Engineering who are investigating the use of human pluripotent stem cells (hPSCs) to engineer pancreatic islets in the lab. A major goal of the research is to develop a method of vascularizing islets in vitro -- literally 'in glass' -- which studies suggest will result in higher viability and enhanced function after the transplant.

A song's structure can be linked to its popularity
Music can elicit strong emotions, which can be hard to describe. A new study has found that a simple change in harmonic structure can contribute to our preference for certain songs. Analyzing the chords of over 500 pop songs between 1958 and 1991, the study reveals a link between those showing higher 'harmonic surprise' (chords that do not usually follow each other) and their popularity in the Billboard Top 100 chart.

Understanding Caribbean mammal extinctions of the past spurs renewed focus on conservation
A Johns Hopkins paleontologist and her collaborative team of scientists report they have clear evidence that the arrival of humans and subsequent human activity throughout the islands of the Caribbean were likely the primary causes of the extinction of native mammal species there. The evidence, they say, highlights the need for urgent human intervention to protect the native mammal species still inhabiting the region.

Brain activity may be predictor of stress-related cardiovascular risk
A pattern of brain activity that occurs during psychological stress may predict bodily reactions, such as surges in our blood pressure, that increase risk for cardiovascular disease. People who have exaggerated responses to stressors, like large rises in blood pressure or heart rate, are at greater risk of developing hypertension and premature death from cardiovascular disease, researchers say.

Ancient Earth's hot interior created 'graveyard' of continental slabs
MIT geologists have found that ancient Earth's hotter interior created a "graveyard" of continental slabs, as higher mantle temperatures than today caused subducting tectonic plates to sink all the way to the Earth's core.

Study finds that gravity, 'mechanical loading' are key to cartilage development
Mechanical loading is required for creating cartilage that is then turned to bone; however, little is known about cartilage development in the absence of gravity. Now, in a study led by the University of Missouri, bioengineers have determined that microgravity may inhibit cartilage formation. Findings reveal that fracture healing for astronauts in space, as well as patients on bed rest here on Earth, could be compromised in the absence of mechanical loading.

How continents were recycled
Researchers from Germany and Switzerland have used computer simulations to analyse how plate tectonics have evolved on Earth over the last three billion years. They show that tectonic processes have changed in the course of the time, and demonstrate how those changes contributed to the formation and destruction of continents. The model reconstructs how present-day continents, oceans and the atmosphere may have evolved.
