Building trustworthy big data algorithms Posted: 29 Jan 2015 02:04 PM PST Much of our reams of data sit in large databases of unstructured text. Finding insights among emails, text documents, and websites is extremely difficult unless we can search, characterize, and classify their text data in a meaningful way. A new algorithm shows better accuracy and reproducibility than the leading algorithm for mining unstructured text. |
Heavy drinking in middle-age may increase stroke risk more than traditional factors Posted: 29 Jan 2015 02:03 PM PST |
FDA approves first-of-kind device to treat obesity Posted: 29 Jan 2015 02:03 PM PST |
Is this the year you join the top one percent? Affluence more fluid than once thought Posted: 29 Jan 2015 01:09 PM PST Here's some good news for the New Year: According to new research, there's a 1 in 9 chance that a typical American will hit the jackpot and join the wealthiest 1 percent for at least one year in her or his working life. And now the bad news: That same research says only an elite few get to stay in that economic stratosphere -- and nonwhite workers remain among those who face far longer odds. |
Complex environments push 'brain' evolution Posted: 29 Jan 2015 01:08 PM PST Little animations trying to master a computer game are teaching neuroscience researchers how the brain evolves when faced with difficult tasks. Neuroscientists have programmed animated critters that they call 'animats.' The critters have a rudimentary neural system made of eight nodes: two sensors, two motors, and four internal computers that coordinate sensation, movement and memory. |
Privacy challenges: Just four vague pieces of info can identify you, and your credit card Posted: 29 Jan 2015 01:08 PM PST Just four fairly vague pieces of information -- the dates and locations of four purchases -- are enough to identify 90 percent of the people in a data set recording three months of credit-card transactions by 1.1 million users. If someone had copies of just three of your recent receipts -- or one receipt, one Instagram photo of you having coffee with friends, and one tweet about the phone you just bought -- would have a 94 percent chance of extracting your credit card records from those of a million other people. This is true, the researchers say, even in cases where no one in the data set is identified by name, address, credit card number, or anything else that we typically think of as personal information. |
Scientists investigate link between skyrocketing sea slug populations, warming seas Posted: 29 Jan 2015 01:08 PM PST |
Structure of world's largest single cell is reflected at the molecular level Posted: 29 Jan 2015 01:07 PM PST |
Generating Mobius strips of light Posted: 29 Jan 2015 12:16 PM PST |
New technique for growing high-efficiency perovskite solar cells Posted: 29 Jan 2015 12:16 PM PST Researchers have revealed a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals. The researchers fabricated planar solar cells from pervoskite materials with large crystalline grains that had efficiencies approaching 18%. |
Powerful tool promises to change the way scientists view proteins Posted: 29 Jan 2015 12:16 PM PST |
Erectile dysfunction drugs could protect liver from sepsis-induced damage Posted: 29 Jan 2015 12:16 PM PST |
In a role reversal, RNAs proofread themselves Posted: 29 Jan 2015 12:16 PM PST Building a protein is a lot like a game of telephone: information is passed along from one messenger to another, creating the potential for errors. Enzymatic machines proofread at each step, and scientists have uncovered a new quality control mechanism along this path. But in a remarkable role reversal, the proofreading isn't done by an enzyme. Instead, one of the messengers itself has a built-in mechanism to prevent errors. |
Where did the missing oil go? New study says some is sitting on the Gulf floor Posted: 29 Jan 2015 12:15 PM PST |
CAT scan of nearby supernova remnant reveals frothy interior Posted: 29 Jan 2015 11:30 AM PST Cassiopeia A, or Cas A for short, is one of the most well studied supernova remnants in our galaxy. But it still holds major surprises. Astronomers have now generated a new 3-D map of its interior using the astronomical equivalent of a CAT scan. They found that the Cas A supernova remnant is composed of a collection of about a half dozen massive cavities -- or 'bubbles.' |
First-ever view of protein structure may lead to better anxiety drugs Posted: 29 Jan 2015 11:30 AM PST When new medicines are invented, the drug may hit the intended target and nullify the symptoms, but nailing a bull's eye -- one that produces zero side effects -- can be quite elusive. New research has, for the first time, revealed the crystal structure of a key protein, TSPO, which is associated with several forms of anxiety disorders. |
Posted: 29 Jan 2015 11:30 AM PST Atmospheric physicists predict that global warming will not lead to an overall increasingly stormy atmosphere, a topic debated by scientists for decades. Instead, strong storms will become stronger while weak storms become weaker, and the cumulative result of the number of storms will remain unchanged. |
Individuals may fail to navigate complex tradeoffs in privacy decision-making Posted: 29 Jan 2015 11:30 AM PST |
Key element in circadian clock speed discovered Posted: 29 Jan 2015 11:30 AM PST |
New minimally invasive test identifies patients for Barrett's esophagus screening Posted: 29 Jan 2015 11:30 AM PST |
Baleen whales hear through their bones Posted: 29 Jan 2015 11:30 AM PST Understanding how baleen whales hear has posed a great mystery to marine mammal researchers. Biologists reveal that the skulls of at least some baleen whales, specifically fin whales in their study, have acoustic properties that capture the energy of low frequencies and direct it to their ear bones. |
Public and scientists express strikingly different views about science-related issues Posted: 29 Jan 2015 11:30 AM PST |
Research about unique cardinal revealed Posted: 29 Jan 2015 11:29 AM PST A biological sciences professor is receiving attention for his research and publication on a bilateral gynandromorph bird found in the wild. More specifically, the bird has the brownish-gray feathered appearance of a female cardinal on its right side and that of a male cardinal's red feathers on its left side. |
New clues about a brain protein with high affinity for valium Posted: 29 Jan 2015 11:29 AM PST Valium, one of the best known antianxiety drugs, produces its calming effects by binding with a particular protein in the brain. But the drug has an almost equally strong affinity for a completely different protein. New studies revealing atomic level details of this secondary interaction might offer clues about Valium's side effects and point the way to more effective drugs. |
Texting may be more suitable than apps in treatment of mental illness Posted: 29 Jan 2015 11:11 AM PST Texting may be a more suitable treatment aid for those with mental illness than mobile applications.This is the key finding of a new study led by researchers from Clemson University in collaboration with researchers from Indiana University and the Centerstone Research Institute. The study was published in the journal Personal and Ubiquitous Computing. |
Gobal patterns of specialized feeding in insect herbivores revealed Posted: 29 Jan 2015 11:11 AM PST After decades of field work from dozens of sites around the world, and after two years of combing through and analyzing data, researchers have reported on global patterns in the diets of insect herbivores. They report that most insect herbivores, such as caterpillars, find and feast on just one kind of plant in any one location, rather than eating everything in sight. |
Bird watchers help federal agencies pinpoint conservation priorities Posted: 29 Jan 2015 11:11 AM PST Migratory birds are a little like college students moving from home to school and back over the year. With each move they switch landlords, encountering new rules and different living conditions. That's the finding of one of the most detailed assessments of bird ranges ever conducted, work begun as part of the State of the Birds 2011 report. |
Canceled flights: For monarch butterflies, loss of migration means more disease Posted: 29 Jan 2015 10:29 AM PST Ecologists have found that sedentary winter-breeding monarch butterflies are at increased risk of disease, a discovery that could apply to other migratory species as well. But, for the monarchs, there may be a relatively simple solution: the monarchs' winter-breeding behavior is made possible by the presence of tropical milkweed, and the authors recommend that gardeners gradually replace it with native milkweeds as they become available. |
Genetically engineered antibody-based molecules show enhanced hiv-fighting abilities Posted: 29 Jan 2015 10:29 AM PST Capitalizing on a new insight into HIV's strategy for evading antibodies -- proteins produced by the immune system to identify and wipe out invading objects such as viruses -- researchers have developed antibody-based molecules that are more than 100 times better than our bodies' own defenses at binding to and neutralizing HIV, when tested in vitro. The work suggests a novel approach that could be used to engineer more effective HIV-fighting drugs. |
Added fructose is a principal driver of type 2 diabetes, experts argue Posted: 29 Jan 2015 10:29 AM PST Recent studies have shown that added sugars, particularly those containing fructose, are a principal driver of diabetes and pre-diabetes, even more so than other carbohydrates. Clinical experts challenge current dietary guidelines that allow up to 25 percent of total daily calories as added sugars, and propose drastic reductions in the amount of added sugar, and especially added fructose, people consume. |
Crucial protective role observed for farnesoid-x receptor in cholestatic liver injury Posted: 29 Jan 2015 10:28 AM PST The farnesoid-X receptor (FXR), also known as the chief regulator of bile acid metabolism, is thought to play a role in some hepatobiliary and gastrointestinal disorders. A recent study has demonstrated dysfunctional intestinal FXR-signaling in a rat model of cholestatic liver injury, accompanied by intestinal bacterial translocation (BTL) and increased permeability and inflammation. Notably, a highly potent, selective FXR agonist obeticholic acid (INT-747) counteracted these effects, suggesting a potential new therapeutic avenue for liver disease. |
Walking on ice takes more than brains: 'Mini-brain' in spinal cord aids in balance Posted: 29 Jan 2015 10:28 AM PST Scientists have discovered how a "mini-brain" in the spinal cord aids in balance. Much of the balancing act that our bodies perform when faced with a task such as walking on an icy surface happens unconsciously, thanks to a cluster of neurons in our spinal cord that function as a "mini-brain" to integrate sensory information and make the necessary adjustments to our muscles so that we don't slip and fall, researchers report. |
Common pesticide may increase risk of ADHD Posted: 29 Jan 2015 09:55 AM PST |
Infants create new knowledge while sleeping Posted: 29 Jan 2015 09:55 AM PST |
Parkinson's gene linked to lung cancer Posted: 29 Jan 2015 09:55 AM PST |
Among gut microbes, strains, not just species, matter Posted: 29 Jan 2015 09:55 AM PST Sophisticated genomic techniques now allow scientists to estimate the strains, not just the species, in samples of the human gut's microbe collection. Differences in the strains of microorganisms present might account for the variable influence the gut's microbe community has on human health and disease. Understanding the effects of various strain combinations on such functions as metabolism, immunity and drug reactions might suggest ways to manipulate the gut microbiome to improve health. |
Ancient 'genomic parasites' spurred evolution of pregnancy in mammals Posted: 29 Jan 2015 09:55 AM PST Large-scale genetic changes that marked the evolution of pregnancy in mammals have been identified by an international team of scientists. They found thousands of genes that evolved to be expressed in the uterus in early mammals. Surprisingly, these genes appear to have been recruited from other tissue types by transposons -- ancient mobile genetic elements sometimes thought of as genomic parasites. The study sheds light on how organisms evolve new morphological structures and functions. |
Cancer fear can impact screening uptake Posted: 29 Jan 2015 09:54 AM PST |
Functioning brain tissue grown in 3-D structure Posted: 29 Jan 2015 09:54 AM PST Researchers have induced human embryonic stem cells to self-organize into a three-dimensional structure similar to the cerebellum, providing tantalizing clues in the quest to recreate neural structures in the laboratory. One of the primary goals of stem-cell research is to be able to replace damaged body parts with tissues grown from undifferentiated stem cells. For the nervous system, this is a particular challenge because not only do specific neurons need to be generated, but they must also be coaxed into connecting to each other in very specific ways. |
New deep-brain imaging reveals separate functions for nearly identical neurons Posted: 29 Jan 2015 09:54 AM PST |
Blame men for political gridlock, study says Posted: 29 Jan 2015 08:37 AM PST Men in survey and experimental data were more likely than women to avoid cross-party political discussion, to judge political arguments based solely on what party is advancing them, and to form strong political opinions about the opposite party's positions without actually listening to the other side's reasoning, researchers report. |
Iceland rises as its glaciers melt from climate change Posted: 29 Jan 2015 08:37 AM PST Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps. In south-central Iceland some sites are moving upward as much as 1.4 inches (35 mm) per year. A new paper is the first to show the current fast uplift of the Icelandic crust is a result of accelerated melting of the island's glaciers and coincides with the onset of warming that began about 30 years ago, the researchers said. |
Ancient skull shows modern humans colonized Eurasia 60-70,000 years ago Posted: 29 Jan 2015 08:37 AM PST |
Invasive species in the Great Lakes by 2063 Posted: 29 Jan 2015 08:35 AM PST The vulnerability of the basin to future invaders has been demonstrated by a new study that calls for regulations to mitigate this threat. The Great Lakes have been invaded by more non-native species than any other freshwater ecosystem in the world. In spite of increasing efforts to stem the tide of invasion threats, the lakes remain vulnerable, according to scientists. If no new regulations are enforced, they predict new waves of invasions and identify some species that could invade the Lakes over the next 50 years. |
Understanding portable biodetection technology for identifying suspcious substances Posted: 29 Jan 2015 08:35 AM PST |
Obesity, diabetes symptoms in mice improved by reversing brain inflammation Posted: 29 Jan 2015 07:43 AM PST Using an antioxidant to reverse inflammation in the brain caused by a high-fat diet greatly improves symptoms related to obesity and type 2 diabetes, a new study suggests. The research suggests that butein and other natural compounds that block inflammation in the brain should be vigorously investigated as novel anti-diabetic treatments, he says. |

New potential therapeutic strategy against a very aggressive infant bone cancer Posted: 29 Jan 2015 07:43 AM PST Inhibition of Sirtuin1 protein may be a future treatment option for metastatic Ewing sarcoma, researchers report. Ewing's sarcoma is the second most common bone cancer and affects children and adolescents. Currently, if diagnosed in time and there is no metastasis, it can be cured in 80% of cases but between 25% and 30% of cases are diagnosed when there is already metastasized, at which low survival to 30 %. |
Hydrogen sulfide could help lower blood pressure Posted: 29 Jan 2015 07:43 AM PST |
Rapid test kit detects dengue antibodies from saliva Posted: 29 Jan 2015 07:42 AM PST Finding out whether you have been infected with dengue may soon be as easy as spitting into a rapid test kit. Researchers have developed a paper-based disposable device that will allow dengue-specific antibodies to be detected easily from saliva within 20 minutes. This device is currently undergoing further development for commercialization. |
Diet, nutrition essential for mental health Posted: 29 Jan 2015 07:42 AM PST |
Posted: 29 Jan 2015 07:41 AM PST Investigators have studied whether working memory of children living in rural poverty is distinct from the working memory profiles of children in urban poverty. The results clearly suggest that school-aged low-socioeconomic status children exhibit both verbal and visuospatial working memory deficits, possibly due to increased levels of stress. Children in urban poverty showed symmetric working memory weaknesses, while children in rural poverty had worse visuospatial working memory than verbal working memory. |
Posted: 29 Jan 2015 07:40 AM PST Researchers say they can predict the spread of flu a week into the future with as much accuracy as Google Flu Trends can display levels of infection right now. The study uses social network analysis and combines the power of Google Flu Trends' "big data" with traditional flu monitoring data from the U.S. Centers for Disease Control and Prevention (CDC). |
Novel eye-tracking technology detects concussions, head injury severity Posted: 29 Jan 2015 07:40 AM PST New research could move the medical community one step closer toward effectively detecting concussion and quantifying its severity. Neuroscientists and concussion experts present a unique, simple and objective diagnostic tool for concussion that can be utilized in the emergency room or, one day, on the sidelines at sporting events. The study utilized a novel eye-tracking device to effectively measure the severity of concussion or brain injury in patients presenting to emergency departments following head trauma. |
