|  Key step in molecular 'dance' that duplicates DNA deciphered  | Scientists have captured new details of the biochemical interactions necessary for cell division. The research may suggest ways for stopping cell division when it goes awry. | Read More » Artificial cells to study molecular crowding and gene expression created  | Scientists have approximated molecular crowding in an artificial cellular system and found that tight quarters help the process of gene expression, especially when other conditions are less than ideal. | Read More » Scientists solve a 14,000-year-old ocean mystery  | At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed with phytoplankton, amoeba-like foraminifera and other tiny creatures, who thrived in large numbers until the productivity ended -- as mysteriously as it began -- just a few hundred years later. | Read More » Antiviral enzyme contributes to several forms of cancer  | Researchers have discovered that a human antiviral enzyme causes DNA mutations that lead to several forms of cancer. | Read More » Is the Ice in Greenland in Growing Decline? Continuous satellite monitoring of ice sheets needed to better predict sea-level rise  | The length of the satellite record for the Greenland and Antarctic ice sheets is currently too short to tell if the recently reported speed-up of ice loss will be sustained in the future or if it results from natural processes, according to a new study. | Read More » Boldly illuminating biology's 'dark matter'  | Microbial dark matter comprises the invisible infrastructure of life that can have profound influences on the most significant environmental processes. By employing next generation DNA sequencing of single cell genomes, researchers are systematically filling in the bacterial and archaeal tree of life's uncharted branches. | Read More » Undiagnosed pre-diabetes highly prevalent in early Alzheimer's disease study  | When a neurologist began enrolling people with mild to moderate Alzheimer's disease into a nationwide study last year, he expected to find only a handful of participants with undiagnosed glucose intolerance, as all the patients were already under a doctor's care and those with known diabetes were excluded. But the scientists said he was "shocked" by how many study participants were found to have pre-diabetes -- a finding that is triggering important questions. | Read More » DNA flaws may contribute to cancer risk in people with type 2 diabetes  | A type of genetic abnormality linked to cancer is more common in people with type 2 diabetes than the rest of the population, a new study has found. | Read More » Kill-switch controls immune-suppressing cells, scientists discover  | Scientists have uncovered the mechanism that controls whether cells that are able to suppress immune responses live or die. | Read More » Sexual reproduction only second choice for powdery mildew  | Genetically, powdery mildew is perfectly adapted to its host plants. Evidently, sexual reproduction and new combinations of genetic material usually prove disadvantageous for the fungus. Asexual reproduction, however, is considerably more successful for mildew, as plant biologists demonstrate. Nonetheless, the fungus still allows itself a sexual reproduction cycle. | Read More » Some volcanoes 'scream' at ever-higher pitches until they blow their tops  | Swarms of small earthquakes can precede a volcanic eruption, sometimes resulting in "harmonic tremor" resembling sound from some musical instruments. A new analysis shows tremor during a 2009 sequence at Alaska's Redoubt Volcano glided to substantially higher frequencies, then stopped abruptly just before six of the eruptions. | Read More » Drug candidate leads to improved endurance  | Scientists have shown that a drug candidate significantly increases exercise endurance in animal models. | Read More » Imaging electron pairing in a simple magnetic superconductor  | Using a technique to measure the energy required for electrons to pair up and how that energy varies with direction, scientists have identified the factors needed for magnetically mediated superconductivity—as well as those that aren't. | Read More » Proteins involved in immunity potentially cause cancer  | A set of proteins involved in the body's natural defenses produces a large number of mutations in human DNA, according to a new study. The findings suggest that these naturally produced mutations are just as powerful as known cancer-causing agents in producing tumors. | Read More » Strong pregnancy outcomes for survivors of childhood cancer  | New research finds that almost two-thirds of female survivors of childhood cancer who tried unsuccessfully for at least a year to conceive eventually got pregnant. | Read More » Phytoplankton social mixers: Tiny ocean plants use turbulence for travel to social gatherings  | Scientists have shown that the motility of phytoplankton also helps them determine their fate in ocean turbulence. | Read More » Early spatial reasoning predicts later creativity and innovation, especially in STEM fields  | Exceptional spatial ability at age 13 predicts creative and scholarly achievements over 30 years later, according to new results. | Read More » Very preterm babies show bonding difficulties despite parental sensitivity  | A new study suggests that some very preterm babies have trouble bonding with their care-givers due to neurological impairments and not to the way their parents interact with them. | Read More » New retroviruses found in polar bear 'Knut' and panda 'Bao Bao'  | Endogenous retroviruses (ERVs) are viruses that at some point in the past inserted themselves into the nuclear genome of a host's germ cell. Once integrated in a germ cell the virus would be passed on from one generation to the next and the endogenous retroviral genome would therefore be inherited to new species that evolve from the original host. | Read More » Smallest puzzle in the world  | Researchers have created three puzzle pieces of less than 1 mm in size each that may be put together to make what is likely, the smallest puzzle in the world. For production, researchers used a new process to manufacture microstructured casting molds. Inexpensive series production is combined with highest precision on the microscale to produce such things as components for watches, engines, or medical products. Now, large series of smallest parts can be injection-molded with the highest accuracy. | Read More » The universe or the brain: Where does math originate?  | Four scientists debate whether math is an inherent part of the universe, or merely how our brains cope with - and explain - our environment. | Read More » Surprise finding reveals how adaptive our immune systems can be  | Studies of patients with immunodeficiencies involving single gene mutations can reveal a great deal about our immune systems, especially when actual symptoms do not accord with clinical expectations. Australian scientists acknowledge such a gap between expectation and reality in a new study, which examines people with "Autosomal Dominant Hyper IgE Syndrome." | Read More » Biochemists uphold law of physics  | Experiments by biochemists show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein molecules -- specifically, a protein that unwinds DNA. | Read More » New form of carbon: Grossly warped 'nanographene'  | By introducing multiple odd-membered ring defects into a graphene lattice, researchers have experimentally demonstrated that the electronic properties of graphene can be modified in a predictable manner through precisely controlled chemical synthesis. | Read More » Brain discovery could help schizophrenics  | The discovery of brain impairment in mice may eventually lead to better therapies for people with schizophrenia and major depression. | Read More » How to keep kids engaged with educational games  | If you want teams of students to stay engaged while playing educational games, you might want them to switch seats pretty often. That's one finding from a pilot study that evaluated how well middle school students were able to pay attention to game-based learning tasks. | Read More » Free market is best way to combat climate change, study suggests  | The best way to reduce carbon emissions and combat climate change is through the use of market forces, according to a new study. | Read More » Attractive and successful: In bonobos, attractive females are more likely to win conflicts against males  | While intersexual dominance relations in bonobos never have been thoroughly studied in the wild, several ideas exist of how females attain their dominance status. Some researchers suggest that bonobo female dominance is facilitated by females forming coalitions which suppress male aggression. Others think of an evolutionary scenario in which females prefer non-aggressive males which renders male aggressiveness to a non-adaptive trait. | Read More » Black-legged ticks linked to encephalitis in New York state  | The number of tick-borne illnesses reported to the U.S. Centers for Disease Control and Prevention is on the rise. Lyme disease leads the pack, with some 35,000 cases reported annually. In the Northeast, the black-legged ticks that spread Lyme disease also infect people with other maladies, among them anaplasmosis, babesiosis, and -- now -- Powassan encephalitis. | Read More » Taking the 'random' out of a random laser  | Random Lasers are tiny structures emitting light irregularly into different directions. Scientists have now shown that these exotic light sources can be accurately controlled. | Read More » Hubble finds new Neptune moon: Smallest known moon in the Neptunian system  | NASA's Hubble Space Telescope has discovered a new moon orbiting the distant blue-green planet Neptune, the 14th known to be circling the giant planet. | Read More » Physicists offer novel insight into experimental cancer treatment  | Physicists have carried out new research into how the heating effect of an experimental cancer treatment works. | Read More » | |
