BUFFALO, N.Y. - Most people rarely sing publicly outside of a duty-bound rendition of "Happy Birthday." And since that particular song is usually offered as a group performance, even the reluctant join in the spirit of the occasion, hoping their individual shortcomings will be cloaked by the chorus. "I can't sing," says the hesitant performer. But a University at Buffalo psychologist believes that most people are not as bad at singing as they might think and he is collaborating on the development of an online test that will evaluate participants' ability to match specific ...

Boulder, Colo. -- Nov. 10, 2014 -- When the double asteroid Patroclus-Menoetius passed directly in front of a star on the night of Oct. 20, a team of volunteer astronomers across the U.S. was waiting. Observing the event, known as an occultation, from multiple sites where each observer recorded the precise time the star was obscured, yielded the first accurate determination of the two objects' size and shape. The analysis was led by Dr. Marc W. Buie, staff scientist in Southwest Research Institute's (SwRI) Space Studies Department in Boulder, Colo. The team effort was ...

Scientists at the University of Arizona have discovered what might be the closest thing to "baby photos" of our solar system. A young star called HD 95086 is found to have two dust belts, analogous to the asteroid and Kuiper belts in the Solar System, surrounded by a large dust halo that only young planetary systems have. Similar dust structures are also found around another, slightly older star called HR 8799, where four massive planets occupy the large gap between the two belts. HR 8799, the first star found to host four directly imaged planets, is often referred ...

A new class of apps and wireless devices used by private pilots during flights for everything from GPS information to data about nearby aircraft is vulnerable to a wide range of security attacks, which in some scenarios could lead to catastrophic outcomes, according to computer scientists at the University of California, San Diego and Johns Hopkins University. They presented their findings Nov. 5 at the 21st ACM Conference on Computer and Communications Security in Scottsdale, Ariz. ` Researchers examined three combinations of devices and apps most commonly used by private ...

Regulation of a single, specific gene in a brain region related to drug addiction and depression is sufficient to reduce drug and stress responses, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published October 27 online in the journal Nature Neuroscience. The Mount Sinai study focuses on epigenetics, the study of changes in the action of human genes caused, not by changes in DNA code we inherit from our parents, but instead by molecules that regulate when, where and to what degree our genetic material is activated. Previous research ...

System 05B degenerated into a remnant low pressure area on Nov. 8 and lingered near the east-central coast of India for two days before dissipating on Nov. 10. The tropical cyclone's western edge spread over land on Sunday, Nov. 9 while the center of the low-level circulation remained over open waters of the Bay of Bengal. On that day, 05B's remnants were centered near 14.0 north latitude and 83.8 east longitude, about 215 miles east-northeast of Chennai, India. Infrared imagery from satellites on Nov. 9 indicated that the low-level circulation center of the storm was ...

URBANA, Ill. - Dating couples who have moved toward marriage over the course of their relationship remember accurately what was going on at each stage of their deepening commitment. But couples whose commitment to each other has stagnated or regressed are far less accurate in their memories of their relationships, says a new University of Illinois study. "People like to feel that they're making progress as a couple. If they're not--if, in fact, the relationship is in trouble--they may have distorted recollections that help them feel like they're moving forward because ...

PORTLAND, Ore. - Use of "antibiograms" in skilled nursing facilities could improve antibiotic effectiveness and help address problems with antibiotic resistance that are becoming a national crisis, researchers conclude in a new study. Antibiograms are tools that aid health care practitioners in prescribing antibiotics in local populations, such as a hospital, nursing home or the community. They are based on information from microbiology laboratory tests and provide information on how likely a certain antibiotic is to effectively treat a particular infection. The recent ...

Alexandria, Va. -- On March 13, 1989, a geomagnetic storm spawned by a solar outburst struck Earth, triggering instabilities in the electric-power grid that serves much of eastern Canada and the U.S. The storm led to blackouts for more than 6 million customers and caused tens of millions of dollars in damages and economic losses. More than 25 years later, the possibility of another such catastrophe still looms, and the day-to-day effects of space weather on electrical systems remain difficult to quantify. Now, a new study correlating electrical insurance claims with geomagnetic ...

The rapidly melting ice sheets on the coast of West Antarctica are a potential major contributor to rising ocean levels worldwide. Although warm water near the coast is thought to be the main factor causing the ice to melt, the process by which this water ends up near the cold continent is not well understood. Using robotic ocean gliders, Caltech researchers have now found that swirling ocean eddies, similar to atmospheric storms, play an important role in transporting these warm waters to the Antarctic coast--a discovery that will help the scientific community determine ...

Interstitial lung disease is a significant risk factor for lung inflammation following stereotactic body radiation therapy for lung cancer. DENVER - Pretreatment interstitial lung disease (ILD) is a significant risk factor for developing symptomatic and severe radiation pneumonitis in stage I non-small cell lung cancer (NSCLC) patients treated with stereotactic body radiation therapy (SBRT) alone. ILD is a group of diseases that cause scarring and stiffing of the tissue and space around the air sacs in the lungs, which results in diminished gas exchange. The incidence ...

As part of an international collaboration, scientists at Chalmers University of Technology have demonstrated how noise in a microwave amplifier is limited by self-heating at very low temperatures. The results will be published in the prestigious journal Nature Materials. The findings can be of importance for future discoveries in many areas of science such as quantum computers and radio astronomy. Many significant discoveries in physics and astronomy are dependent upon registering a barely detectable electrical signal in the microwave regime. A famous example of this ...

This news release is available in French. The motor neurons that innervate muscle fibres are essential for motor activity. Their degeneration in many diseases causes paralysis and often death among patients. Researchers at the Institute for Stem Cell Therapy and Exploration of Monogenic Diseases (I-Stem - Inserm/AFM/UEVE), in collaboration with CNRS and Paris Descartes University, have recently developed a new approach to better control the differentiation of human pluripotent stem cells, and thus produce different populations of motor neurons from these cells in only ...

AUSTIN, Texas -- Researchers at the Cockrell School of Engineering at The University of Texas at Austin have achieved a milestone in modern wireless and cellular telecommunications, creating a radically smaller, more efficient radio wave circulator that could be used in cellphones and other wireless devices, as reported in the latest issue of Nature Physics. The new circulator has the potential to double the useful bandwidth in wireless communications by enabling full-duplex functionality, meaning devices can transmit and receive signals on the same frequency band at ...

Researchers from the Norwegian University of Science and Technology (NTNU) and the University of Cambridge in the UK have demonstrated that it is possible to directly generate an electric current in a magnetic material by rotating its magnetization. The findings reveal a novel link between magnetism and electricity, and may have applications in electronics. The electric current generation demonstrated by the researchers is called charge pumping. Charge pumping provides a source of very high frequency alternating electric currents, and its magnitude and external magnetic ...

LA JOLLA, CA--November 10, 2014--Chemists at The Scripps Research Institute (TSRI) and the Shanghai Institute of Organic Chemistry have described a method for creating and modifying organic compounds that overcomes a major limitation of previous methods. The advance opens up a large number of novel chemical structures for synthesis and evaluation, for example, as candidate pharmaceuticals. The new method was designed to avoid an unwanted side effect--a diversion of a catalyst molecule to the wrong location--that prevents chemists from manipulating many organic compounds ...

The Southern Ocean plays an important role in the exchange of carbon dioxide between the atmosphere and the ocean. One aspect of this is the growth of phytoplankton, which acts as a natural sponge for carbon dioxide, drawing the troublesome greenhouse gas from the atmosphere into the sea. When these plankton die they can sink to the bottom of the ocean and store some of the carbon dioxide they have absorbed, a process scientists call the "biological carbon pump". Although many areas of the Southern Ocean are rich in nutrients, they often lack iron, which limits phytoplankton ...

Cold Spring Harbor, NY - Think about all the things you are doing at this moment. As your eyes scan across the lines of this article, maybe your brain is processing the smell of coffee brewing down the hall and the sound of leaf blowers outside your window. Maybe you are tapping your foot and spinning a pen between your fingers. At any given moment, your brain is simultaneously processing a multitude of information from your senses while supporting a dizzying array of behaviors. How is all this information processed at once? The provisional answer, for decades, has centered ...

COLLEGE PARK, Md. -- Researchers at the University of Maryland have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components. The structure is called a nanopore: a tiny hole in a ceramic sheet that holds electrolyte to carry the electrical charge between nanotube electrodes at either end. The existing device is a test, but the bitsy battery performs well. First author Chanyuan Liu, a graduate student in materials science & engineering, says that it can be ...

OAK RIDGE, Tenn., Nov. 10, 2014--For more than 50 years, scientists have debated what turns particular oxide insulators, in which electrons barely move, into metals, in which electrons flow freely. Some scientists sided with Nobel Prize-winning physicist Nevill Mott in thinking direct interactions between electrons were the key. Others believed, as did physicist Rudolf Peierls, that atomic vibrations and distortions trumped all. Now, a team led by the Department of Energy's Oak Ridge National Laboratory has made an important advancement in understanding a classic transition-metal ...

Cold Spring Harbor, NY - There are roughly 20,000 genes and thousands of other regulatory "elements" stored within the three billion letters of the human genome. Genes encode information that is used to create proteins, while other genomic elements help regulate the activation of genes, among other tasks. Somehow all of this coded information within our DNA needs to be read by complex molecular machinery and transcribed into messages that can be used by our cells. Usually, reading a gene is thought to be a lot like reading a sentence. The reading machinery is guided ...

Thousands of never-before-seen genetic variants in the human genome have been uncovered using a new genome sequencing technology. These discoveries close many human genome mapping gaps that have long resisted sequencing. The technique, called single-molecule, real-time DNA sequencing (SMRT), may now make it possible for researchers to identify potential genetic mutations behind many conditions whose genetic causes have long eluded scientists, said Evan Eichler, professor of genome sciences at the University of Washington, who led the team that conducted the study. "We ...

UCLA neuroscientists discovered that statins, a popular class of cholesterol drugs, reverse the learning deficits caused by a mutation linked to a common genetic cause of learning disabilities. Published in the Nov. 10 advance online edition of Nature Neuroscience, the findings were studied in mice genetically engineered to develop the disease, called Noonan syndrome. The disorder can disrupt a child's development in many ways, often causing unusual facial features, short stature, heart defects and developmental delays. No treatment is currently available. "Noonan ...

Thanks to research performed at RIKEN's SACLA x-ray free electron laser facility in Japan, the dream of analyzing the structure of large, hard-to-crystallize proteins and other bio molecules has come one step closer to reality. In the study published in Nature Methods, researchers used a newly developed grease to suspend small crystals of lysozyme, glucose isomerase, thaumatin, and fatty acid-binding protein type-3, which they then analyzed using the revolutionary serial femtosecond crystallography method. Crystallography, which was first performed just a century ago, ...

A team of engineers and scientists has identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes and advanced physics experiments. The findings, detailed in the November 10 issue of the journal Nature Materials, could have implications for the future design of transistors and other electronic components. The electronic noise the team identified is related to the temperature of the electrons in a given device, which in turn is governed by heat transfer due to packets ...
