Junctions between nanotubes have high resistance, slowing down the current and creating hotspots. The researchers use these hot spots to trigger a local chemical reaction that deposits metal that nano-solders the junctions. | Read More » Mach 1000 shock wave lights supernova remnant  | When a star explodes as a supernova, the material blasted outward from the explosion still glows hundreds or thousands of years later, forming a picturesque supernova remnant. What powers such long-lived brilliance? In the case of Tycho's supernova remnant, astronomers have discovered that a reverse shock wave racing inward at Mach 1000 (1,000 times the speed of sound) is heating the remnant and causing it to emit X-ray light. | Read More » Ancient minerals: Which gave rise to life?  | Life originated as a result of natural processes that exploited early Earth's raw materials. Scientific models of life's origins almost always look to minerals for such essential tasks as the synthesis of life's molecular building blocks or the supply of metabolic energy. But this assumes that the mineral species found on Earth today are much the same as they were during Earth's first 550 million years -- the Hadean Eon -- when life emerged. A new analysis of Hadean mineralogy challenges that assumption. | Read More » Swarming insect provides clues to how the brain processes smells  | Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action. However, there is often more than one odor in the environment, such as in coffee shops or grocery stores. How does our brain process multiple odors received simultaneously? | Read More » Archaeological discoveries confirm early date of Buddha's life  | Archaeologists working in Nepal have uncovered evidence of a structure at the birthplace of the Buddha dating to the sixth century B.C. This is the first archaeological material linking the life of the Buddha -- and thus the first flowering of Buddhism -- to a specific century. | Read More » Companies that screen social media accounts alienate job candidates  | Research shows companies that screen the social media accounts of job applicants alienate potential employees – making it harder for them to attract top job candidates. In some cases, social media screening even increases the likelihood that job candidates may take legal action against the offending company. | Read More » Bad proteins branch out: Misfolded proteins are capable of forming tree-like aggregates  | Researchers find that misfolded proteins form branched structures, which may have implications for Alzheimer's and other aggregation diseases. | Read More » The collared treerunner is more than a single species  | The lowland tropics were once though filled with widespread species, while moderate and higher elevations were thought to contain species with more restricted distributions. That idea is turning out to be partially incorrect. A new study describes four species once considered to be the collared treerunner, a lizard known to the scientific community as Plica plica. | Read More » A plant which acclimatizes with no exterior influence  | Plants have a love-hate relationship with sunlight. While some wavelengths are indispensable to them for performing photosynthesis, others, such as UV-B, are deleterious. Therefore, plants are equipped to detect these highly toxic rays and mount their defenses. Biologists have now generated a transgenic plant which acclimatizes constitutively, regardless of the level of UV-B. This plant possesses a constantly active receptor, which endows it with a higher UV resistance, associated with increased flavonoid production, substances which function as a 'sunscreen' and as antioxidants. | Read More » CSI-type study identifies snakehead  | Biologists are breathing a collective sigh of relief after learning that a monstrous fish found in a Burnaby, B.C., pond is not a northern snakehead. But their identification of its correct identity is still a serious concern. | Read More » Flashes of brilliance: Roots of superfluorescent bursts from quantum wells discovered  | Spontaneous bursts of coherent light from solid-state materials shed new light on how particles interact and may lead to ultrahigh-speed optoelectronic devices for telecommunications. | Read More » Search for habitable planets should be more conservative, experts say  | Scientists should take the conservative approach when searching for habitable zones where life-sustaining planets might exist, according to experts. | Read More » Increasing cropping frequency offers opportunity to boost food supply  | Harvesting existing cropland more frequently could substantially increase global food production without clearing more land for agriculture, according to a new study. | Read More » The good news in bad news  | Psychology shows that it doesn't take much to put you in a bad mood. And being in a bad mood slows your reaction time and affects your basic cognitive abilities like speech, writing, and counting. But new research now reveals that repeated exposure to a negative event neutralizes its effect on your mood and your thinking. The study has broad implications for understanding our emotions. | Read More » School climate key to preventing bullying  | To effectively prevent bullying, schools need to understand positive school climate, use reliable measures to evaluate school climate and use effective prevention and intervention programs to improve the climate, a recent paper explains. | Read More » Extrovert, introvert children not equally influenced by plate size  | New research indicates that extroverted and introverted children respond differently to environmental cues, such as plate size, when it comes to portion control. | Read More » A touch of garlic helps kill contaminants in baby formula  | Garlic may be bad for your breath, but it's good for your baby, according to a new study. This study is the first to identify two compounds derived from garlic -- diallyl sulfide and ajoene -- that significantly reduce the contamination risk of Cronobacter sakazakii in the production of dry infant formula powder. | Read More » The reality behind Europe's response to climate change  | British cities – unlike their counterparts on the mainland - are taking the lead in making plans to curb and handle the impact of climate change. A new study analyzed the relevant strategic policies and planning documents of 200 urban areas in eleven European countries. They found that one in every three European cities has no plans on the table to reduce greenhouse gas emissions, while seven in every ten urban areas have no formal adaptation plans in place. | Read More » Making sense of sensation in autism  | Occupational therapy helps children with autism improve their ability to perform everyday better than standard behavioral therapy. | Read More » Viruses are as simple as they are 'smart'  | Viruses are as simple as they are "smart": too elementary to be able to reproduce by themselves, they exploit the reproductive "machinery" of cells, by inserting pieces of their own DNA so that it is transcribed by the host cell. To do this, they first have to inject their own genetic material into the cells they infect. An international team of researchers has studied how this occurs and how long it takes for this process to be completed. | Read More » EMRs provide method to discover new disease associations  | Researchers are repurposing genetic data and electronic medical records to perform the first large-scale phenome-wide association study. | Read More » Dying from food allergy less likely than being murdered  | A person with a food allergy is more likely to be murdered than to die from a severe reaction, according to a new study. | Read More » Battle against bee blood eating Acari  | Mexico is one of the top five bee producing countries worldwide and the second in exportation. However, the beekeepers can see their production affected by the attack of a parasite, the Varroa acari, which feeds on hemolymph of the bees. | Read More » Eating sushi can increase risk of cardiovascular disease  | A new study showed that tuna sashimi contains the highest levels of methylmercury in fish-sushi, based on samples taken from across the USA. | Read More » PCBs still affecting health decades later  | Although PCBs have been banned in the United States since 1979, a researcher has found that higher levels of the toxin was associated with lower cognitive performance in seniors. | Read More » Experiencing awe increases belief in supernatural  | Awe-inspiring moments -- like the sight of the Grand Canyon or the aurora borealis -- might increase our tendency to believe in God and the supernatural, according to new research. | Read More » Got the sniffles?
