Theranos -- a health care industry revolution or a marketing phenomenon?
Professor of Clinical Biochemistry Eleftherios P. Diamandis looks over the science behind innovative and revolutionary blood tests invented by Elizabeth Holmes that could apparently reinvent the lab diagnostics. Through scrupulous examination of five key issues, he reaches the conclusion that many of the company's claims do not stand up to scientific review.

Earth's daily rotation period encoded in an atomic-level protein structure
A collaborative group of Japanese researchers has demonstrated that the Earth's daily rotation period (24 hours) is encoded in the KaiC protein at the atomic level, a small, 10 nm-diameter biomolecule expressed in cyanobacterial cells.The results of this joint research will help elucidate a longstanding question in chronobiology: How is the circadian period of biological clocks determined?

Giving atoms their marching orders
Building self-assembled 'molecular straws' from bis-urea macrocycles, Linda Shimizu of the University of South Carolina has developed a new nanotube system that can be used to directly compare single-file diffusion dynamics with Fickian diffusion dynamics. She and co-author Russ Bowers of the University of Florida use hyperpolarized xenon-129 NMR to study gas transport dynamics in two highly homogeneous nanotubes, one with a narrow-bore, hollow interior that can accommodate xenon gas atoms only in single file.

Nanowires could be the LEDs of the future
The latest research from the Niels Bohr Institute shows that LEDs made from nanowires will use less energy and provide better light. The researchers studied nanowires using X-ray microscopy and with this method they can pinpoint exactly how the nanowire should be designed to give the best properties. The results are published in the scientific journal, ACS Nano.

Bionic eye clinical trial results show long-term safety, efficacy vision-restoring implant
The three-year clinical trial results of the retinal implant popularly known as the 'bionic eye,' have proven the long-term efficacy, safety and reliability of the device that restores vision in those blinded by a rare, degenerative eye disease. The findings show that the Argus II significantly improves visual function and quality of life for people blinded by retinitis pigmentosa. They are being published online today in Ophthalmology, the journal of the American Academy of Ophthalmology.

Physicists fine-tune control of agile exotic materials
Physicists have found a way to control the length and strength of waves of atomic motion called polaritons that have promising potential uses such as fine-scale imaging and the transmission of information within tight spaces. Heterostructures made from graphene and hexagonal boron nitride support hybrid plasmon-phonon polaritons that can be tuned electronically.

Nanowire implants offer remote-controlled drug delivery
A team of researchers has created a new implantable drug-delivery system using nanowires that can be wirelessly controlled. The nanowires respond to an electromagnetic field generated by a separate device, which can be used to control the release of a preloaded drug. The system was tested in mice with spinal cord injuries.

Toward tiny, solar-powered sensors
Last week, at the Symposia on VLSI Technology and Circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it, even at the extremely low power levels characteristic of tiny solar cells. Previous experimental ultralow-power converters had efficiencies of only 40 or 50 percent.

With 300 kilometers per second to new electronics
It may be significantly easier to design electronic components in future. Scientists at the Max Planck Institute for Chemical Physics of Solids have discovered that the electrical resistance of a compound of niobium and phosphorus increases enormously when the material is exposed to a magnetic field. The Max Planck researchers, together with colleagues from the High-Field Magnet Laboratories at the Helmholtz-Zentrum Dresden-Rossendorf and at the Radboud University in the Netherlands, published the new findings on niobium phosphide in the journal Nature Physics.

Soft core, hard shell -- the latest in nanotechnology
Medical science is placing high hopes on nanoparticles as in future they could be used, for example, as a vehicle for targeted drug delivery. In collaboration with an international team of researchers, scientists at the Helmholtz Zentrum Muenchen have for the first time succeeded in assaying the stability of these particles and their distribution within the body. Their results, which have been published in the journal Nature Nanotechnology, show that a lot of research is still needed in this field.
