  • Nanonets give rust a boost as agent in water splitting’s hydrogen harvest – Coating a lattice of tiny wires called Nanonets with iron oxide – known more commonly as rust – creates an economical and efficient platform for the process of water splitting, an emerging clean fuel science that harvests hydrogen from water, Boston College researchers report.
  • Firefly protein lights pathway to improved detection of blood clots – The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots, scientists are reporting. Their study appears in the ACS' monthly journal Bioconjugate Chemistry.
  • Sleep deprivation increases stroke and heart disease risk – Prolonged sleep deprivation increases the risk of suffering from a stroke or heart disease, according to a major long-term study based on the experiences of hundreds of thousands of people across eight countries.
  • Rehabilitating captured CO2 – Rather than burying it underground, companies are developing processes that use carbon dioxide emissions as chemical starting materials.
  • A More Accurate Kilogram Thanks To A More Accurate Avogadro Constant – A milestone in the international Avogadro project coordinated by the Physikalisch-Technische Bundesanstalt (PTB) has been reached – with the aid of a single crystal of highly enriched 28Si, the Avogadro constant has now been measured more precisely than ever before, with a relative overall uncertainty of 3 x 10^-8.

    Within the scope of the redefinition of the kilogram, the value NA = 6.02214078(18) x 10^23 mol-1 allows a more exact realization of this unit.
  • Researchers produce world’s first programmable nanoprocessor – Engineers and scientists collaborating at Harvard University and the MITRE Corporation have developed and demonstrated the world's first programmable nanoprocessor.
  • Sleepwalking ‘linked to chromosome fault’ – Scientists believe they have discovered the genetic code that makes some people sleepwalk. By studying four generations of a family of sleepwalkers they traced the fault to a section of chromosome 20.
  • Prostate cancer ‘gene test’ hope – Experts believe they can develop a genetic screening test that can tell doctors which men with prostate cancer need aggressive treatment.
  • 3-D Images Hint To Earth’s Big Split – A new method of taking very detailed 3-D images of minute samples of material under extreme pressures is helping tell the story of the biggest transformation Earth has ever undergone.
  • Trial and error: The brain learns from mistakes – Dr. Peter Scheiffele's research group at the Biozentrum of the University of Basel has discovered that a protein traditionally associated with bone development is responsible for correcting errors while neurons connect to their correct partners in the cerebellum.
