Making sense of metallic glass Posted: 08 Feb 2016 06:38 PM PST Vitrified metals, or metallic glasses, are at the frontier of materials science research. But much about them remains poorly understood. A team is trying to figure out the rules that govern metallic glass's creation. They are doing this by looking at metallic glasses under extreme pressures. High-pressure research can be used to probe structure on an atomic level and understand a material's state of order or disorder. |
A disposable, highly sensitive biosensing system Posted: 08 Feb 2016 06:37 PM PST |
New evidence gives women informed choice in the prolapse surgery debate Posted: 08 Feb 2016 06:37 PM PST |
Exposure to air pollution 30 years ago associated with increased risk of death Posted: 08 Feb 2016 06:36 PM PST Exposure to air pollution more than 30 years ago may still affect an individual's mortality risk today, according to new research. Highest risks were seen for respiratory disease, such as bronchitis, emphysema and for pneumonia. Air pollution also affected mortality risk from cardiovascular diseases, such as heart disease. |
Posted: 08 Feb 2016 03:34 PM PST From paper towels to cups to plastic bottles, products made from recycled materials permeate our lives. One notable exception is building materials. Why can't we recycle concrete from our deteriorating infrastructure for use as material in new buildings and bridges? It's a question that a team of researchers is examining. |

Newer pain management strategies can lead to quicker, shorter recovery after total knee replacement Posted: 08 Feb 2016 03:30 PM PST According to a new literature review , a team-based care approach (consisting of the patient, family members, the orthopaedic surgeon and other medical practitioners) on total knee replacement (TKR) procedures, in conjunction with newer pain management strategies, is key to maximizing patient outcomes. |
What's nature worth? Study helps put a price on groundwater and other natural capital Posted: 08 Feb 2016 03:29 PM PST |
Social hormone promotes cooperation in risky situations Posted: 08 Feb 2016 03:29 PM PST |
Cockroach inspires robot that squeezes through cracks Posted: 08 Feb 2016 03:29 PM PST Ever wonder how roaches are able to get into anything, no matter how tight the seams? Biologists have now shown that the American cockroach can flatten its body to one-fifth normal running height to squeeze through cracks as small as two stacked pennies, and can run at high speed when flattened by half. These features were reproduced in a squishy robot that can run even when flattened: ideal for search and rescue. |
Sleep deprivation linked to false confessions Posted: 08 Feb 2016 03:29 PM PST |
Asian monsoon season weakens as the Indian Ocean warms Posted: 08 Feb 2016 12:15 PM PST The variable nature of the summer monsoon season makes Southern Asia one of the most vulnerable regions to natural disasters associated with climate change, such as droughts and floods. A recent study has revealed that the warming of the Indian Ocean is reducing the intensity of the summer monsoon season and drying up the subcontinent. In a region that is home to a large part of the world's population, dynamic climate modelling represents a major challenge in the prevention of the human and economic consequences of climatic hazards. |
A new role for vitamin B6 in plants Posted: 08 Feb 2016 12:15 PM PST Vitamin B6 is essential for all living organisms. Researchers have discovered an unexpected role for this micronutrient, in relation to nitrogen metabolism. The results indicate that one of the vitamers informs the plant of its content in ammonium, a basic nitrogen compound needed for the biosynthesis of various molecules essential for life. In the future, vitamin B6 could be used to ascertain the nitrogen status of plants and eventually prevent the overuse of nitrogen-containing fertilizers, say authors of a new report. |

New research identifies drug target for dengue virus Posted: 08 Feb 2016 10:44 AM PST No vaccine or drug has yet become available against the Dengue virus. A flavivirus like the newly prominent Zika virus, Dengue has become a leading cause of serious illness and death in some Asian and Latin American countries. Now a team of investigators has data suggesting that a protein in dengue virus that goes by the scientific name, NS4B, would make a promising target for antiviral drug development. |
Persistent ADHD associated with overly critical parents Posted: 08 Feb 2016 10:44 AM PST |
A step closer to understanding fertilization Posted: 08 Feb 2016 10:44 AM PST Researchers have taken a step closer to understanding the mechanism that leads to the fusion of egg and sperm at fertilization. Using the technique X-ray crystallography, they have determined the 3-D structure of Juno, a mammalian egg protein essential for triggering gamete fusion. Their findings are not only interesting from an evolutionary perspective, but also reveal the shape of a possible target for future non-hormonal contraceptives. |
Experts urge extreme caution on 'rewilding' to save wild places Posted: 08 Feb 2016 10:44 AM PST Efforts to 'rewild' the landscape have become increasingly popular in some corners, but researchers say that scientific evidence supporting the potential benefits of this form of restoration is limited at best. As history has shown, the introduction of species into new places is often met with unexpected, negative consequences for the environment. |
Higher cellulolytic activity of a vital microorganism explained Posted: 08 Feb 2016 09:48 AM PST Researchers say that a better understanding of a bacterium could lead to cheaper production of cellulosic ethanol and other advanced biofuels. Their discovery was made during an investigation into the performance of Clostridium thermocellum. The scientists found the microorganism utilizes the common cellulase degradation mechanisms known today (free enzymes and scaffolded enzyme attached to the cell), and a new category of scaffolded enzymes not attached to the cell. |
Brain scars in multiple sclerosis patients reveal possible cause of taste problems Posted: 08 Feb 2016 09:48 AM PST |
Veterans Affairs health system faces significant challenges, studies find Posted: 08 Feb 2016 09:48 AM PST A series of reports prepared as part of a Congressionally mandated review of the Veterans Affairs (VA) health care system finds that demands on the VA will continue to increase through the end of the decade. Veterans who rely on the VA for health care are less healthy, with higher rates of chronic conditions and mental illness, than veterans who do not use the VA health system. |

Earth-like planets have Earth-like interiors Posted: 08 Feb 2016 09:42 AM PST Every school kid learns the basic structure of the Earth: a thin outer crust, a thick mantle, and a Mars-sized core. But is this structure universal? Will rocky exoplanets orbiting other stars have the same three layers? New research suggests that the answer is yes -- they will have interiors very similar to Earth. |

Scientists propose 'pumpjack' mechanism for splitting, copying DNA Posted: 08 Feb 2016 09:38 AM PST New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry. |
Chiral magnetic effect generates quantum current Posted: 08 Feb 2016 09:38 AM PST A new way to generate very low-resistance electric current in a new class of materials has been discovered by scientists. The discovery, which relies on the separation of right- and left-"handed" particles, points to a range of potential applications in energy, quantum computing, and medical imaging, and possibly even a new mechanism for inducing superconductivity-the ability of some materials to carry current with no energy loss. |
Turning the volume of gene expression up and down Posted: 08 Feb 2016 09:38 AM PST |
Millennials say one thing but do another when choosing chocolate Posted: 08 Feb 2016 08:30 AM PST |
Long-term picture offers little solace on climate change Posted: 08 Feb 2016 08:30 AM PST Climate change projections that look ahead one or two centuries show a rapid rise in temperature and sea level, but say little about the longer picture. A new looks at the next 10,000 years, and finds that the catastrophic impact of another three centuries of carbon pollution will persist millennia after the carbon dioxide releases cease. |
Traffic-related air pollution linked to facial dark spots Posted: 08 Feb 2016 08:29 AM PST A large scale study that included women from Germany and China has demonstrated a link between levels of traffic-related air pollution and air pollution-associated gases with the formation of dark spots on the skin, known as lentigenes. The most pronounced changes were observed on the cheeks of Asian women over the age of 50. |
Old trees reveal Late Antique Little Ice Age (LALIA) around 1,500 years ago Posted: 08 Feb 2016 08:29 AM PST A dendroclimatologist and his fellow researchers were able for the first time to precisely reconstruct the summer temperatures in central Asia for the past 2,000 years. This was made possible by new tree-ring measurements from the Altai mountains in Russia. The results complement the climatological history of the European Alps, stretching back 2,500 years, that the research team has published in the past. |
A deep look into a single molecule Posted: 08 Feb 2016 08:29 AM PST The interaction of thermal energy from the environment with motional degrees of freedom is well known and often referred to as Brownian motion (also thermal motion). But in the case of polar molecules, the internal degrees of freedom -- in particular the rotational quantum state -- are also influenced by the thermal radiation. So far, the detection of the rotational state was only possible by destroying the molecule. Now, report scientists, the quantum state of a molecular ion has been measured live and in a non-destructive fashion for the first time. |
