Criminals don't have to pick your pocket to get what they want out of your mobile. But a certifiably secure operating platform is being developed by researchers so that consumers can be confident that their mobile data is safe.
A UK Department for Health-commissioned survey in 2004 concluded that 1 in 10 British children aged 5-16 are diagnosed with mental disorders. Childhood stress, psychological problems and self-abuse are increasing. Gone are the hazy days when kids could run free all day and play. Through play “children develop… an emergent sense of competence … feelings of ‘belonging’, ‘usefulness’, and subsequent well-being”. When deprived of play, children lack social connectivity and have less ‘mental wellness’.
Like mobsters following strict orders, newly engineered molecules called “ubiquibodies” can mark specific proteins inside a cell for destruction -- a molecular kiss of death that is paving the way for new drug therapies and powerful research tools. For instance, in a cancer cell in which a certain protein has been identified as contributing to the disease, the ubiquibody could reduce or eliminate the protein from within by targeting that specific protein only, the authors suggest.
New research calls into question the very foundations of emotion science. It's a concept that had become universally understood: humans experience six basic emotions -- happiness, sadness, anger, fear, disgust, and surprise -- and use the same set of facial movements to express them. What's more, we can recognize emotions on another's face, whether that person hails from Boston or Borneo. The only problem with this concept, according to new research, is that it isn't true at all. Researchers have found that even basic human emotions are in fact not universally perceived.
The specific proportions of immune cells in a blood sample form a profile that can indicate disease or exposure to a toxicant. A new epigenetic technique provides a reliable way to detect such profiles, even in archived blood where whole cells may no longer be intact. All the current means of counting immune cells in a blood sample require whole cells, but the new system relies on something far less ephemeral: DNA. Its use of hardy strands of genetic material allows it to handle even archived samples where cells have lost their physical integrity.
The Galápagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved. Now research is providing a better picture of the subterranean plumbing system that feeds the Galápagos volcanoes.
It may seem normal: As we age, we misplace car keys, or can't remember a name we just learned or a meal we just ordered. But researchers say memory trouble doesn't have to be inevitable, and they've found a drug therapy that could potentially reverse this type of memory decline. The drug can't yet be used in humans, but the researchers are pursuing compounds that could someday help the population of aging adults who don't have Alzheimer's or other dementias but still have trouble remembering day-to-day items.
Three promising biomarkers being studied to detect Alzheimer’s disease in its early stages appear to undergo a surprising shift as patients develop symptoms of dementia, researchers report. Scientists found in a recent study that the levels of markers of neuronal injury increase in the spinal fluid for a decade or more before the onset of dementia. But in a new twist, the research shows for the first time that they later reverse course, decreasing as symptoms of memory loss and mental decline appear.
Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning extremely rapidly. This first direct measurement of the spin of such a distant black hole is an important advance for understanding how black holes grow over time.
Researchers have succeeded in producing a prototype of a vibration-damping material that could change the world of mechanics forever. The material of the future is not only able to damp vibrations completely. It can also specifically conduct certain frequencies further.
The Center on Secondary Education for Students with Autism Spectrum Disorders (CSESA) developed its approach from research in several fields. Because of the complex educational needs of many students with autism, it was important to develop a comprehensive program for high schools. CSESA focuses on understanding emotions, developing friendships, and social problem-solving -- and it draws from new research in implementation science so that schools can put the program into place quickly and effectively.
Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme precision of measurements.
A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies, report scientists. Surprisingly, the gene described, doublesex, is already well-known for its critical role in sexual differentiation in insects.
D-Wave quantum processor passes tests indicating that it uses special laws of quantum mechanics to operate. A key task for researchers has been to determine whether D-Wave processors operate as hoped -- using the special laws of quantum mechanics to offer potentially higher-speed processing, instead of operating in a classical, traditional way.
Making your own stuff with a 3-D printer is vastly cheaper than what you'd pay for manufactured goods, even factoring in the cost of buying the plastic filament. Yet, you can drive the cost down even more by making your own filament from old milk jugs. And, while you are patting yourself on the back for saving 99 cents on the dollar, there's a bonus: you can feel warm and fuzzy about preserving the environment. Making your own plastic 3-D printer filament from milk jugs uses less energy -- often a lot less -- than recycling milk jugs conventionally.
Like monolingual children, bilingual children prefer to interact with those who speak their mother tongue with a native accent rather than with peers with a foreign accent. "We show biases early on, so it might be necessary to educate all kids, regardless of their linguistic background, about what an accent is and how it doesn't reflect anything about people other than the fact that they are not speaking their native language," says a co-author.
A new bioinspired sponge-like gel shrinks single-handedly, squeezing unspecialized cells inside it and turning them into cells that begin to form teeth. The new material was inspired by the embryo's power to shape organs, and it could enable engineering of new teeth, bone, or other tissues, scientists report.
