Why it snows so much in the frozen north Posted: 20 Dec 2013 05:06 PM PST Scientists have long puzzled over the seemingly ceaseless drizzle of snow drifting down from arctic clouds. Now they may have an explanation. |
Researchers grow liquid crystal 'flowers' that can be used as lenses Posted: 20 Dec 2013 12:45 PM PST A team of material scientists, chemical engineers and physicists has made another advance in their effort to use liquid crystals as a medium for assembling structures. Their earlier studies produced patterns of "defects," useful disruptions in the repeating patterns found in liquid crystals, in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a three-dimensional array shaped like a flower. |
Starless cloud cores reveal why some stars are bigger than others Posted: 20 Dec 2013 11:35 AM PST Massive stars -- those at least 8 times the mass of our Sun -- present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller? Massive stars -- those at least 8 times the mass of our Sun -- present an intriguing mystery: how do they grow so large when the vast majority of stars in the Milky Way are considerably smaller? To find the answer, astronomers used the Atacama Large Millimeter/submillimeter Array telescope to survey the cores of some of the darkest, coldest, and densest clouds in our Galaxy to search for the telltale signs of star formation. |
91 new species described by California Academy Of Sciences in 2013 Posted: 20 Dec 2013 09:10 AM PST In 2013, researchers at the California Academy of Sciences discovered 91 new plant and animal species and two new genera, enriching our understanding of the complex web of life on Earth and strengthening our ability to make informed conservation decisions. The new species, previously unknown to science, include 38 different ants, 12 fishes, 14 plants, eight beetles, two spiders, one reptile, and one amphibian. |
Birth of black hole kills the radio star Posted: 20 Dec 2013 08:40 AM PST Astronomers have discovered a new population of exploding stars that "switch off" their radio transmissions before collapsing into a Black Hole. These exploding stars use all of their energy to emit one last strong beam of highly energetic radiation -- known as a gamma-ray burst -- before they die. |
Scientists discover how immune cells die during HIV infection; Identify potential drug to block AIDS Posted: 19 Dec 2013 11:22 AM PST Research has identified the chain of molecular events that drives the death of the immune system's CD4 T cells as an HIV infection leads to AIDS. Further, they have identified an existing anti-inflammatory drug that blocks the death of these cells -- and now are planning a Phase 2 clinical trial to determine if it can prevent HIV-infected people from developing AIDS. |
New evidence that computers change the way we learn Posted: 19 Dec 2013 10:07 AM PST People who use computers regularly are constantly mapping the movements of their hand and computer mouse to the cursor on the screen. Now, researchers have shown that all that pointing and clicking (the average computer user performs an impressive 7,400 mouse clicks per week) changes the way the brain generalizes movements. |

Early detection of blinding eye disease could be as easy as scanning barcode Posted: 20 Dec 2013 09:08 AM PST A new optical device puts the power to detect eye disease in the palm of a hand. The tool -- about the size of a hand-held video camera -- scans a patient's entire retina in seconds and could aid primary care physicians in the early detection of a host of retinal diseases including diabetic retinopathy, glaucoma and macular degeneration. |

Opposing phenomena possible key to high-efficiency electricity delivery Posted: 19 Dec 2013 11:23 AM PST Researchers report that the coexistence of two opposing phenomena might be the secret to understanding how materials known as high-temperature superconductors -- heralded as the future of powering our homes and communities -- actually work. Such insight could help spur the further development of high-efficiency electric-power delivery. |
Advances in nanotechnology's fight against cancer Posted: 19 Dec 2013 10:12 AM PST Among the most promising advances in the fight against cancer has been the rise of nanomedicine, the application of tiny materials and devices to detect, diagnose and treat disease. Researchers provide one of the most comprehensive assessments to date of research on nanomedicine-based approaches to treating cancer, and offers insight into how researchers can best position nanomedicine-based cancer treatments for FDA approval. |
Supercomputers help researchers identify key molecular switch that controls cell behavior Posted: 17 Dec 2013 12:52 PM PST If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body. |
