Microscopic worms could hold the key to living life on Mars
— 2 Dec 2011 10:26 | BiologyThe astrophysicist Stephen Hawking believes that if humanity is to survive we will have up sticks and colonise space. But is the human body up to the challenge?…
Earthquakes: Water as a lubricant
— 2 Dec 2011 10:23 | Geology and palaeontologyGeophysicists from Potsdam have established a mode of action that can explain the irregular distribution of strong earthquakes at the San Andreas Fault in California. As the science magazine Nature reports in its latest issue, the scientists examined the electrical conductivity of the rocks at great depths, which is closely related to the water content within the rocks. From the pattern of electrical conductivity and seismic activity they were able to deduce that rock water acts as a lubricant…
Simple blood test diagnoses Parkinson's disease long before symptoms appear
— 2 Dec 2011 10:20 | HealthA new research report appearing in the December issue of the FASEB Journal (http://www.fasebj.org) shows how scientists from the United Kingdom have developed a simple blood test to detect Parkinson's disease even at the earliest stages. The test is possible because scientists found a substance in the blood, called 'phosphorylated alpha-synuclein,' which is common in people with Parkinson's disease, and then developed a way to identify its presence in our blood…
Livermore and Russian scientists propose new names for elements 114 and 116

Early sign of Alzheimer's reversed in lab
— 2 Dec 2011 10:14 | HealthOne of the earliest known impairments caused by Alzheimer's disease - loss of sense of smell - can be restored by removing a plaque-forming protein in a mouse model of the disease, a study led by a Case Western Reserve University School of Medicine researcher finds…
Parental controls on embryonic development?
— 2 Dec 2011 10:11 | HealthWhen a sperm fertilises an egg, each contributes a set of chromosomes to the resulting embryo, which at these very early stages is called a zygote. Early on, zygotic genes are inert, so embryonic development is largely controlled by parental factors. The activation of the zygotic genome therefore represents an important transition toward a more autonomous mode of embryonic development, and has been the subject of much speculation and scrutiny. Now, a new study published by Cell Press on December 1st in the journal Developmental Cell suggests that the reach of parental control in the embryo may be longer than we thought…
Newly discovered heart stem cells make muscle and bone
— 2 Dec 2011 10:08 | HealthResearchers have identified a new and relatively abundant pool of stem cells in the heart. The findings in the December issue of Cell Stem Cell, a Cell Press publication, show that these heart cells have the capacity for long-term expansion and can form a variety of cell types, including muscle, bone, neural and heart cells…
BUSM researchers develop blood test to detect membranous nephropathy
— 2 Dec 2011 10:05 | HealthResearch conducted by a pair of physicians at Boston University School of Medicine (BUSM) and Boston Medical Centre (BMC) has led to the development of a test that can help diagnose membranous nephropathy in its early stages. The test, which is currently only offered in the research setting and is awaiting commercial development, could have significant implications in the diagnosis and treatment of the disease. Currently, the only way to diagnose the disease is through a biopsy…
