Ultrafast remote switching of light emission
Researchers from Eindhoven University of Technology can now for the first time remotely control a miniature light source at timescales of 200 trillionth of a second. They published the results on Sept. 2014 in the online journal Nature Nanotechnology. Physicists from the Photonics and Semiconductor Nanophysics group at Eindhoven, under the leadership of prof. Andrea Fiore, have developed a way of remotely controlling the nanoscale light sources at an extremely short timescale. These light sources are needed to be able to transmit quantum information.

New diagnostic approach for autism in Tanzania
Researchers at Brown University and the University of Georgia have developed and tested an approach for diagnosing autism in Tanzania, where such clinical assessment and intervention services are rare. The assessment battery combines several existing but culturally adapted techniques into a protocol that the researchers tested with 41 children at two Tanzanian sites.

Rating the planet's oceans
Researchers from UCSB's National Center for Ecological Analysis and Synthesis helped produce the first Ocean Health Index that includes all the Earth's oceans.

The cultural side of science communication
Do we think of nature as something that we enjoy when we visit a national park and something we need to 'preserve?' Or do we think of ourselves as a part of nature? A bird's nest is a part of nature, but what about a house? The answers to these questions reflect different cultural orientations. They are also reflected in our actions, our speech and in cultural artifacts, according to a new Northwestern University study.

Comprehensive Study of allergic deaths in US finds medications are main culprit
Medications are the leading cause of allergy-related sudden deaths in the US, according to an analysis conducted by researchers at Montefiore Medical Center and Albert Einstein College of Medicine . The study, published online today in the Journal of Allergy and Clinical Immunology, also found that the risk of fatal drug-induced allergic reactions was particularly high among older people and African-Americans and that such deaths increased significantly in the US in recent years.

Blades of grass inspire advance in organic solar cells
Briseno's research group is one of very few in the world to design and grow organic single-crystal p-n junctions. He says, 'This work is a major advancement in the field of organic solar cells because we have developed what the field considers the 'Holy Grail' architecture for harvesting light and converting it to electricity.' The breakthrough in morphology control should have widespread use in solar cells, batteries and vertical transistors, he adds.

UCI study uncovers important process for immune system development
Research by UC Irvine immunologists reveals new information about how our immune system functions, shedding light on a vital process that determines how the body's ability to fight infection develops.

Medicaid and Uninsured patients obtain new patient appointments most easily at FQHCs
Federally Qualified Health Centers granted new patient appointments to Medicaid beneficiaries and uninsured patients at higher rates than other primary care practices, in addition to charging less for visits, according to results of a new 10-state University of Pennsylvania study published this month in Medical Care.

A new dimension for integrated circuits: 3-D nanomagnetic logic
Electrical engineers at the Technische Universitat Munchen have demonstrated a new kind of building block for digital integrated circuits. Their experiments show that future computer chips could be based on three-dimensional arrangements of nanometer-scale magnets instead of transistors. As CMOS, the main enabling technology of the semiconductor industry, approaches fundamental limits, Technische Universitat Munchen researchers and collaborators at Notre Dame are exploring 'magnetic computing' as an alternative. They report their latest results in the journal Nanotechnology.
