| Zebrafish neurons may lead to understanding of birth defects like spina bifida Posted: 18 Feb 2014 03:51 PM PST Using zebrafish, scientists can determine how individual neurons develop, mature and support basic functions like breathing, swallowing and jaw movement. Researchers say that learning about neuronal development and maturation in zebrafish could lead to a better understanding of birth defects such as spina bifida in humans. The zebrafish, a tropical freshwater fish similar to a minnow and native to the southeastern Himalayan region, is well established as a key tool for researchers studying human diseases, including brain disorders. |
| Regenerating orthopedic tissues within the human body Posted: 18 Feb 2014 03:51 PM PST Performing tissue repair with stem cells typically requires applying copious amounts of growth factor proteins -- a task that is very expensive and becomes challenging once the developing material is implanted within a body. A team of biomedical engineers has developed a polymer scaffold for growing cartilage that includes gene therapy vectors to induce stem cells to produce the growth factors they need. The new technique -- biomaterial-mediated gene delivery -- is shown to produce cartilage at least as good biochemically and biomechanically as if the growth factors were introduced in the laboratory. |
| Almost 13 million smoking deaths could be prevented in China by 2050 Posted: 18 Feb 2014 03:51 PM PST China is home to about one third of the world's smokers and reducing smoking in China could have an enormous public health impact, even on a global scale. Complete implementation of World Health Organization Framework Convention on Tobacco Control recommended policies in China would prevent almost 13 million smoking related deaths by 2050, suggests a new article. |
| The number of tumor cells spread to sentinel lymph nodes affects melanoma prognosis Posted: 18 Feb 2014 03:50 PM PST Cancer cell spread to the sentinel node -- the lymph node to which cancer cells are most likely to spread from a primary tumor -- is a risk factor for melanoma death. The prognosis of a patient largely depends on the number of disseminated cancer cells per million lymphocytes in the sentinel node. Even very low numbers were found to be predictive for reduced survival. |
| A brain circuit for recognizing change Posted: 18 Feb 2014 03:48 PM PST To answer the seemingly simple question "Have I been here before?" we must use our memories of previous experiences to determine if our current location is familiar or novel. Scientists have now identified a region of the hippocampus, called CA2, which is sensitive to even small changes in a familiar context. The results provide the first clue to the contributions of CA2 to memory and may help shed light on why this area is often found to be abnormal in the schizophrenic brain. |
| Los Angeles' vulnerability to future sea level rise projected Posted: 18 Feb 2014 03:48 PM PST Los Angeles, a metropolis perched on the edge of a coast, can expect to experience sea level rise of as much as two feet due by 2050 due to climate change, according to current projections. |
| Unusual new HIV drug resistance mechanism revealed Posted: 18 Feb 2014 03:48 PM PST For the millions of people living with HIV/AIDS, antiretroviral drugs can be a lifeline, slowing the progress of viral infection. Unfortunately, studies have shown that these benefits can be short-lived: therapy can lead to mutations in the HIV genetic code, which can make the virus resistant to drugs. However, researchers have made some new insight into how the therapy functions and how therapy-induced point mutations actually confer drug resistance. |
| Synthetic molecular oscillator discoveries may help create artificial cells Posted: 18 Feb 2014 01:34 PM PST Researchers have made important discoveries regarding the behavior of a synthetic molecular oscillator, which could serve as a timekeeping device to control artificial cells. The team developed methods to screen thousands of copies of this oscillator using small droplets, and found, surprisingly, that the oscillators inside these small droplets behave in a very diverse way in terms of period, amplitude and phase. |
| Baby hearts need rhythm to develop correctly Posted: 18 Feb 2014 01:30 PM PST Researchers report that they have taken an important step toward the goal of growing replacement heart valves from a patient's own cells by determining that the mechanical forces generated by the rhythmic expansion and contraction of cardiac muscle cells play an active role in the initial stage of heart valve formation. |
| Can you boost your brain power through video? Posted: 18 Feb 2014 01:30 PM PST Watching video of simple tasks before carrying them out may boost the brain's structure, or plasticity, and increase motor skills, according to a new study. Brain plasticity is the brain's ability to flex and adapt, allowing for better learning. The brain loses plasticity as it ages. |
| Rife with hype, exoplanet study needs patience and refinement Posted: 18 Feb 2014 12:38 PM PST Despite many trumpeted results, few 'hard facts' about exoplanet atmospheres have actually been collected, and most of these data are of 'marginal utility,' according to a review of exoplanet research by an astrophysicist. The dominant methods for studying exoplanet atmospheres are not intended for planets trillions of miles from Earth. Instead, the future of exoplanet study should focus on the more difficult but comprehensive method of spectrometry. |
| Gene test developed to accurately classify brain tumors Posted: 18 Feb 2014 12:38 PM PST Scientists have developed a mathematical method for classifying forms of glioblastoma, an aggressive and deadly type of brain cancer, through variations in the way these tumor cells 'read' genes. Their system was capable of predicting the subclasses of glioblastoma tumors with 92 percent accuracy. With further testing, this system could enable physicians to accurately predict which forms of therapy would benefit their patients the most. |
| Scientists successfully simulate 'neutronics' — the behavior of neutrons in a reactor core Posted: 18 Feb 2014 12:37 PM PST Scientists and engineers developing more accurate approaches to analyzing nuclear power reactors have successfully tested a new suite of computer codes that closely model "neutronics" — the behavior of neutrons in a reactor core. |
| Researchers home in on Alzheimer's disease: Supercomputer helps guide new drug designs Posted: 18 Feb 2014 12:37 PM PST Researchers studying peptides using a supercomputer have found new ways to elucidate the creation of the toxic oligomers associated with Alzheimer's disease. |

The app is aimed at younger women who are most likely to be in abusive relationships, and are less likely than older adults to seek formal safety resources, instead looking to peers or technology for help and advice. |
| Controlling magnetism with an electric field Posted: 18 Feb 2014 11:33 AM PST Scientists are now proposing a novel approach to achieve greater memory density while producing less heat: by using an electric field instead of a current to turn magnetism on and off, thereby encoding the electrical devices. |
| Battery small enough to be injected, energetic enough to track salmon Posted: 18 Feb 2014 11:33 AM PST Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon. The battery is just slightly larger than a long grain of rice, however is not the world's smallest battery. Engineers have created batteries far tinier than the width of a human hair, but those smaller batteries don't hold enough energy to power acoustic fish tags. The new battery is small enough to be injected into an organism and holds much more energy than similar-sized batteries. |
| What cooperation and conflict in an insect's society can teach us about social acceptance Posted: 18 Feb 2014 11:33 AM PST A new study looks at colonies of social wasps and explores the acceptance of individuals not related to each other, in a highly organized and adaptable society. The findings show that the age of the individual, and of the colony, defines the costs and benefits of accepting new members into a group. |
| Evolution stuck in slime for a billion years Posted: 18 Feb 2014 11:33 AM PST Researchers are providing a new explanation as to why life remained as little more than slime for a billion years, before rapidly diversifying in the 'Cambrian explosion of life'. Using a new technology originally developed for mineral exploration, the team has shown how varying levels of oxygen and biologically-important elements in the ancient oceans might have triggered the major evolutionary events that brought us here today. |
| Study of 2011 Illinois flood will lead to better preparedness Posted: 18 Feb 2014 11:32 AM PST In May 2011, when the US Army Corps of Engineers used explosives to breach a levee south of Cairo, Ill., diverting the rising waters of the Mississippi and Ohio rivers to prevent flooding in the town, about 130,000 acres of Missouri farmland were inundated. Researchers took advantage of this "once-in-a-scientific-lifetime" occurrence to study the damage. Their study showed that landscape vulnerabilities can be mapped ahead of time to help communities prepare for extreme flooding. |
| When a black hole shreds a star, a bright flare tells the story Posted: 18 Feb 2014 11:32 AM PST A new study explains what happens during the disruption of a normal sun-like star by a supermassive black hole.

Society requires a renewable source of fuel that is widely distributed, abundant, inexpensive and environmentally clean. Society needs cheap hydrogen. |
| Wings, tails, fins: Study looks at how animals propel themselves Posted: 18 Feb 2014 09:44 AM PST The wonder of animal movement -- from the tiniest of insects to the largest fish in the sea -- has been a subject of mystery for ages. But when it comes to animal propulsion, there are almost infinite kinds, but also limits that can't be pushed or breakdowns will occur, according to an unusual study. |
| Posted: 18 Feb 2014 08:43 AM PST The energy involved in carbon cap formation does not dictate the chirality of a single-walled nanotube, according to theoretical research. The work contributes to the continuing search for a way to grow nanotubes of the same selected chirality. |
| Sochi games influenced by Lake Placid winter Olympics of 1932 Posted: 18 Feb 2014 08:42 AM PST Eight crashes that sent more than a dozen competitors to the hospital marred bobsled practice runs leading up to the 1932 winter Olympic games in Lake Placid, N.Y., but as dramatic as those incidents were, they also provide insight into more ordinary factors that continue to influence the Olympics, according to new research. |
| Ion beams pave way to new kinds of valves for use in spintronics Posted: 18 Feb 2014 08:42 AM PST Researchers have tested a new approach to fabricating spin valves. Using ion beams, they structured an iron aluminum alloy in such a way as to subdivide the material into individually magnetizable regions at the nanometer scale. The alloy functions as a spin valve, which is of interest for use in spintronics. Not only does this technology use electron charge for purposes of information storage and processing, it also draws on its inherent magnetic properties (that is, its spin). |

The results show that heavier men harbor more potentially pathogenic species of bacteria in their nose, compared with slimmer, more traditionally attractive men. |
| Infected Tasmanian devils reveal how cancer cells evolve in response to humans Posted: 18 Feb 2014 07:07 AM PST Tasmanian Devil Facial Tumor Disease (DFTD) has ravaged the world's largest carnivorous marsupial since it emerged in 1996, resulting in a population decline of over 90%. Conservation work to defeat the disease has including removing infected individuals from the population and new research explains how this gives us a unique opportunity to understand how human selection alters the evolution of cancerous cells. DFTD is an asexually reproducing clonal cell line, which during the last 16 years has been exposed to negative effects as infected devils, approximately 33% of the population, have been removed from one site, the Forestier Peninsula, in Tasmania between 2006 and 2010. |
| Increase in Arctic cyclones is linked to climate change Posted: 18 Feb 2014 07:07 AM PST Winter in the Arctic is not only cold and dark; it is also storm season when hurricane-like cyclones traverse the northern waters from Iceland to Alaska. These cyclones are characterized by strong localized drops in sea level pressure, and as Arctic-wide decreases in sea level pressure are one of the expected results of climate change, this could increase extreme Arctic cyclone activity, including powerful storms in the spring and fall. A new study uses historical climate model simulations to demonstrate that there has been an Arctic-wide decrease in sea level pressure since the 1800's. |
| Extreme weather images in the media cause fear and disengagement with climate change Posted: 18 Feb 2014 07:06 AM PST Extreme weather images represent human suffering and loss. They are iconic of climate change and are symbols of its natural impacts. Reporting on extreme weather has increased over the last few years. In the past social scientists, and media and communication analysts have studied how climate change is depicted in the text of media and social media. While researchers have become increasingly interested in climate change images, they have not yet studied them with respect to symbolizing certain emotions. |
