The search for happiness

Using MRI to find where happiness happens


Exercising, meditating, scouring self-help books... we go out of our way to be happy, but do we really know what happiness is? Wataru Sato and his team at Kyoto University have found an answer from a neurological perspective. Overall happiness, according to their study, is a combination of happy ...


Birth of photo-sensitive magnets

New functional photonic materials and devices based on magnetism


Members of the spin-photonics team at Tokyo Tech including KosukeYamamoto, a master's course graduate student at the School of Interdisciplinary Science and Engineering, Yoshitaka Kitamoto, professor at the same school, and Hiro Munekata, professor at the Imaging Science and Engineering ...


Detecting small metallic contaminants in food via magnetization

A practical metallic-contaminant detecting system using three high-Tc RF superconducting quantum interference devices (SQUIDs)


The detection of metallic contaminants in foods is important for our health and safety. However, existing inspection methods have limitations. For instance, the X-ray radiation method cannot detect contaminants with sizes smaller than 1 mm with current practical X-ray levels, and it cannot be ...

Measuring the mass of molecules on the nano-scale

By observing the shift in eigenstates of coupled microcantilevers, researchers can measure nanogram-scale mass in a liquid environment with extreme accuracy


Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error - potentially ...

Nano-policing pollution


Pollutants emitted by factories and car exhausts affect humans who breathe in these harmful gases and also aggravate climate change up in the atmosphere. Being able to detect such emissions is a critically needed measure.New research by the Nanoparticles by Design Unit at the Okinawa Institute of ...


Decoding DNA's phonebook


New clues about diseases like inflammatory bowel disorder may be found thanks to a new genomic interactions catalogue by a group of researchers in Japan and the United Kingdom. This research is published in Nature Genetics.Biologists have compiled the most comprehensive catalogue of promoter ...


Rapid and efficient DNA chip technology for testing 14 major types of food borne pathogens


Toshiba Ltd and Kawasaki City Institute for Public Health collaborate in the development of a rapid and efficient DNA chip technology for testing 14 major types of food borne pathogens for applications in hygiene management in food manufacture, pharmaceuticals, and cosmetics. The researchers are ...


Innovative image sensing technology for early diagnosis of diabetes and Alzheimer’s disease


Professor Kazuaki Sawada and Dr. Takigawa of the National Center for Geriatrics and Gerontology and colleagues at Toyohashi University of Technology have established an easy to use, low-cost, rapid, and high sensitivity semiconductor-imaging based medical diagnostic biosensing system for ...


Discovery of quantum vibrations in 'microtubules' corroborates theory of consciousness


A review and update of a controversial 20-year-old theory of consciousness published in Physics of Life Reviews claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations in "microtubules" inside brain neurons ...
