Astronomy & Space news
Scientists explain why moon rocks contain fewer volatiles than Earth'sScientists at Southwest Research Institute combined dynamical, thermal, and chemical models of the Moon's formation to explain the relative lack of volatile elements in lunar rocks. Lunar rocks closely resemble Earth rocks in many respects, but Moon rocks are more depleted in volatile elements like potassium, sodium, and zinc, which tend to have lower boiling points and vaporize readily. | |
Astronomers explain the low number of discovered grazing planets(Phys.org)—Exoplanet hunters have so far found hundreds of alien worlds using the transit method. They observe the visual brightness of the star, which drops when a planet crosses in front of the parent star's disk. However, only a handful of grazing exoplanets—meaning exoplanets that partially transit the host-star's disc—have been detected and confirmed. Astronomers from the University of Porto in Portugal blame giant dark polar spots on host stars for the difficulties of finding new grazing planets. Their research appears in the November issue of Astronomy & Astrophysics journal. | |

Physicists find clue to formation of magnetic fields around stars and galaxiesAn enduring astronomical mystery is how stars and galaxies acquire their magnetic fields. Physicists Jonathan Squire and Amitava Bhattacharjee at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found a clue to the answer in the collective behavior of small magnetic disturbances. In a paper published in October in Physical Review Letters, the scientists report that small magnetic perturbations can combine to form large-scale magnetic fields just like those found throughout the universe. This research was funded by the DOE Office of Science. | |
Dark matter and particle acceleration in near spacePeering into darkness can strike fear into the hearts of some, but a new space telescope will soon peer into the darkness of "near space" (within a few thousand light years of Earth).

Medicine & Health news
Increased meat consumption, especially when cooked at high temperatures, linked to elevated kidney cancer riskDiets high in meat may lead to an increased risk of developing renal cell carcinoma (RCC) through intake of carcinogenic compounds created by certain cooking techniques, such as barbecuing and pan-frying. As part of a new study from The University of Texas MD Anderson Cancer Center, published online this week in the journal Cancer, researchers also discovered that individuals with specific genetic mutations are more susceptible to the harmful compounds created when cooking at high temperatures. | |
Study finds long-sought protein sensor for the 'sixth sense'—proprioceptionCan you touch a finger to the tip of your nose with your eyes closed? Most of us can, thanks to a sense called proprioception, which tells us where our body parts are relative to each other and our environment. Not surprisingly, this sense is essential for normal movement and balance—walking, for instance. | |

Molecular clocks control mutation rate in human cellsEvery cell in the human body contains a copy of the human genome. Through the course of a lifetime all cells are thought to acquire mutations in their genomes. Some of the mutational processes generating these mutations do so in bursts and these will often be through external exposures such as sunbathing or tobacco smoking. Other mutational processes, however, may be internal to the cell and generate mutations continuously, at a constant rate over decades. If so the mutations they generate will be "clock-like", with the number of mutations present correlating with the age of the person. In research reported in Nature Genetics two clock-like mutational processes have been found in human cells and the rates at which the two clocks tick in different human cell types have been determined. | |
Antibody targets key cancer marker and opens door to better diagnosis, therapyUniversity of Wisconsin-Madison researchers have created a molecular structure that attaches to a molecule on highly aggressive brain cancer and causes tumors to light up in a scanning machine. In mouse models of human brain cancer, their tag is easily seen in a PET scanner, which is commonly used to detect cancer. | |
Protein findings open new avenues to understanding and treatment of schizophreniaStem cells from adult schizophrenia patients form new proteins more slowly than those from healthy people, according to new research. | |
Researchers shed pharmacological light on formerly 'dark' cellular receptorsOur cells are constantly communicating, using neurotransmitters and hormones to signal to each other. Molecular receptors on each cell receive these chemical signals and allow cells to accomplish a task important for health. Astonishingly, for about half of these receptors, the chemical signals remain unknown. These "orphan receptors" are highly expressed in particular tissues but their functions remain a mystery. They are considered "dark" elements of the genome, and yet they hold great potential for drug development for a variety of diseases and conditions. | |
Enormous genetic variation may shield tumors from treatmentThe most rigorous genetic sequencing ever carried out on a single tumor reveals far greater genetic diversity among cancer cells than anticipated. Researchers from the University of Chicago and the Beijing Institute of Genomics estimate that the tumor, about 3.5 centimeters in diameter, contained more than 100 million distinct mutations within the coding regions of its genes—thousands of times more than expected. | |

Poverty influences effects of race and education on pain after knee replacement surgeryNon-white race and lack of education are known risk factors for pain and poorer function after knee replacement surgery. What isn't clear is how a community's poverty level affects the outcomes of having a joint replaced. Findings from a new study conducted by researchers from Hospital for Special Surgery (HSS) suggest that lower socioeconomic status at the community level significantly increases the risk of pain and poor function following a knee replacement. These findings could allow clinicians to more effectively target patients at high risk for poor outcomes and provide support and counseling before their patients undergo the procedure. | |

The life story of stem cellsStem cells ensure the regeneration and maintenance of the body's tissues. Diseases like cancer can arise if they spiral out of control. In collaboration with doctors from Aachen University Hospital, scientists from the Max Planck Institute for Evolutionary Biology in Plön have designed a mathematical model for mapping the development of populations of haematopoietic, i.e. blood-forming, stem cells with advancing age. The model uses the telomeres on the chromosomes of blood cells to do this. These protective covers, which are located at the ends of the chromosomes, shrink each time a cell divides. Thus, it is possible to tell how many times a cell has already divided from its length. Deviations from normal age-related length distribution could be indicative of disease. | |
The first long-haired ones: New wasp group proposed for five new species from IndiaLong accustomed to parasitising spider eggs, a large worldwide genus of wasps has as few as 24 known representatives in India. However, Dr. Veenakumari, ICAR-National Bureau of Agricultural Insect Resources, and her team have recently discovered five new species of these interesting wasps from different parts of the country. Because of their uniqueness and their strong resemblance to each other, as well to aid taxonomic studies they have been considered as constituting a group of their own. The discoveries and the suggestion of 'the first long-haired ones' species group are available in the open-access journal Deutsche Entomologische Zeitschrift. | |
