'Ôhelo (Vaccinium reticulatum Smith) is a small, native Hawaiian shrub in the cranberry family, commonly found at high elevations on the islands of Maui and Hawaii. As people scour the landscape to harvest this delectable berry for use in jam, jelly and pie filling, they unfortunately disrupt the fragile habitats where this plant grows.

In an effort to reduce damage to the environment and meet consumer demands, horticulturist Francis T.P. Zee, with the USDA Agricultural Research Service (ARS) Pacific Basin Agricultural Research Center (PBARC) in Hilo, Hawaii, is evaluating 'ôhelo for small farm production and ornamental use. Zee collaborated with fellow ARS scientists and cooperators at the University of Hawaii at Manoa, Big Island Candies and the Big Island Association of Nurserymen. ARS is the principal intramural scientific research agency of USDA.
Zee and his team selected the offspring of seed-grown plants to create the new cultivar "Kilauea" for berry production. They found 'ôhelo's tiny seeds readily germinated under 20-30 percent shade in well-watered and well-drained potting mixture. Plant hardiness and vigor improved with age, and some seedlings flowered just 10 months after germination, much sooner than the 5 years reported in previous studies. The 16-month-old plants Zee successfully transplanted from the greenhouse to the field produced berries a year later.
Zee also used cuttings and tissue culture to propagate selected 'ôhelo of high ornamental potential. With proper care, young, growing shoots of 'ôhelo can be groomed into vibrant, colorful ornamental potted plants. Since the plant is not seasonal, its readiness for market can be scheduled by trimming and fertilizing. Older potted 'ôhelo plants can be trained into a bonsai and can readily adapt to the office environment.
Zee and PBARC scientists are currently examining the disease and insect problems associated with growing potted 'ôhelo. Full descriptions of Zee's 'ôhelo studies can be found on the University of Hawaii's College of Tropical Agriculture and Human Resources' (CTAHR) website.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
