Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits (qubits). The research, published in Nature Nanotechnology, shows how it is possible to realise this device embedded in a semiconductor chip, and demonstrates the device's ability to confine individual ions at the nanoscale.

Alexandria, VA – December 21, 2012 – the purported last day of a 5,125-year cycle in the Mesoamerican calendar – has been added to an endless list of days when the world has been expected to end. But what are our real chances of being wiped out by a catastrophic event – the kind that has happened in the past and will inevitably occur again someday? In the August issue of EARTH, we explore four of the most probable global events that could change life on Earth forever.

For Immediate Release – July 24, 2012 – (Toronto) – An ongoing survey of Ontario students in grades 7 to 12 conducted for the Centre for Addiction and Mental Health (CAMH) shows that while the majority of students have healthy relationships and report overall good mental and physical health, some negative trends, especially among girls, have raised concerns.

The 2011 Ontario Student Drug Use and Health Survey (OSDUHS) Mental Health and Well-Being Report released today reveals important trends in mental and physical health and risk behaviours among Ontario students.

The first study of a procedure to make three-dimensional "maps" of electrical signals in children's hearts could help cardiologists correct rapid heart rhythms in young patients, according to new research presented at the American Heart Association's Basic Cardiovascular Sciences 2012 Scientific Sessions.

• U.S. college students typically drink more than their non-college peers and are slow to 'mature out' of their harmful drinking patterns.
• A new study examines a combined community-level and campus-level approach to reducing high-risk drinking.
• Findings indicate this approach can decrease both severe and interpersonal consequences of drinking.

CLEMSON, S.C. — Clemson University plant breeders announced a new high-yielding variety of oats.

Named Graham, the new variety grows to medium height, withstands falling over (lodging), matures earlier and produces more seed than comparable varieties.

"Graham has excellent seed yield potential, exceeding the Rodgers variety by 20 bushels per acre at some locations and produces a 32.2-pound bushel compared to 31.9-pound bushel for Rodgers," said Chris Ray, director of the S.C. Crop Improvement Association, which grows certified seed for sale to the public.

COLUMBUS, Ohio - In a new study that has implications for distracted drivers, researchers found that people are better at juggling some types of multitasking than they are at others.

Trying to do two visual tasks at once hurt performance in both tasks significantly more than combining a visual and an audio task, the research found.

Alarmingly, though, people who tried to do two visual tasks at the same time rated their performance as better than did those who combined a visual and an audio task - even though their actual performance was worse.

A clinical study in a remote region of southwest Uganda has demonstrated the feasibility of using a health campaign to rapidly test a community for HIV and simultaneously offer prevention and diagnosis for a variety of other diseases in rural and resource-poor settings of sub-Saharan Africa.

Amsterdam, The Netherlands, July 23, 2012 – American ginseng is reported to have neurocognitive effects, and research has shown benefits in aging, central nervous system disorders, and neurodegenerative diseases. The challenges of incorporating ginseng into food are twofold: it has a bitter taste, and food processing can eliminate its healthful benefits. Reporting in the August issue of the Journal of Dairy Science®, a group of scientists has formulated low-lactose functional milk that maintained beneficial levels of American ginseng after processing.

MADISON – Electrical engineers at The University of Texas at Arlington and at the University of Wisconsin-Madison have devised a new laser for on-chip optical connections that could give computers a huge boost in speed and energy efficiency.

The team published its findings on July 22, 2012 in Nature Photonics.

In a leap forward for laser technology, a team at University of California, Santa Barbara, has developed the first violet nonpolar vertical-cavity surface-emitting lasers (VCSELs) based on m-plane gallium nitride semiconductors.

This recent discovery by LED pioneer Shuji Nakamura and his research team at UCSB is an achievement in VCSEL technology that opens doors for higher optical efficiency lasers at greatly reduced manufacturing costs for a variety of applications.

Cambridge, Mass. — July 22, 2012 — Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish."

PASADENA, Calif.—When one observes a colorful jellyfish pulsating through the ocean, Greek mythology probably doesn't immediately come to mind. But the animal once was known as the medusa, after the snake-haired mythological creature its tentacles resemble.

Summer is just around the corner and it's time to dust off the garden tables and chairs. But garden furniture that has been left in the shade too long is often covered with a slimy film of algae, moss, bacteria and fungi which is difficult or even impossible to remove.

Researchers from the University of California, San Francisco (UCSF) and Makerere University in Uganda have used hair and blood samples from three-month old infants born to HIV-positive mothers to measure the uninfected babies' exposure—both in the womb and from breast-feeding—to antiretroviral medications their mothers were taking. The results, they said, are surprising.
