The migration and interaction routes of prehistoric humans throughout the islands of Oceania can be retraced using genetic differences between paper mulberry plants, a tree native to Asia cultivated for fibers to make paper and introduced into the Pacific in prehistoric times to make barkcloth. Daniela Seelenfreund of the University of Chile and Andrea Seelenfreund of the Academia de Humanismo Cristiano University, Chile report on prehistoric human movements based on the genetic analysis of this plant in a new paper published June 19 in the open-access journal PLOS ONE.

First-ever successful mind-controlled robotic arm without brain implants
A team of researchers from Carnegie Mellon University, in collaboration with the University of Minnesota, has made a breakthrough in the field of noninvasive robotic device control. Using a noninvasive brain-computer interface (BCI), researchers have developed the first-ever successful mind-controlled robotic arm exhibiting the ability to continuously track and follow a computer cursor.

Researchers use biological evolution to inspire machine learning
As Charles Darwin wrote in at the end of his seminal 1859 book On the Origin of the Species, "whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." Scientists have since long believed that the diversity and range of forms of life on Earth provide evidence that biological evolution spontaneously innovates in an open-ended way, constantly inventing new things. However, attempts to construct artificial simulations of evolutionary systems tend to run into limits in the complexity and novelty which they can produce. This is sometimes referred to as "the problem of open-endedness." Because of this difficulty, to date, scientists can't easily make artificial systems capable of exhibiting the richness and diversity of biological systems.

Study reveals roots of Parkinson's in the brain
Researchers from King's College London have uncovered the earliest signs of Parkinson's disease in the brain, many years before patients show any symptoms. The results, published in The Lancet Neurology, challenge the traditional view of the disease and could potentially lead to screening tools for identifying people at greatest risk.

New laser therapy seeks to halt the progression of age-related vision loss
There are 200 million people in the world living with age-related macular degeneration (AMD), and in approximately a fifth of these cases, the disease progresses to an advanced stage, leading to visual impairment. Advanced AMD is divided into wet and dry forms. While wet AMD can be treated with medical injections, approximately four fifths of advanced AMD cases are of the dry form, for which there is currently no medical treatment.

Early research shows a way to develop effective therapies against pancreatic cancer
Pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer, is the fifth most common cause of death from cancer in the UK and the third in the United States. Deaths from PDAC outnumber those from breast cancer despite the significant difference in incidence rates.

Survivors of breast cancer face increased risk of heart disease
Thanks to advanced medical treatments, women diagnosed with breast cancer today will likely survive the disease. However, some treatment options put these women at greater risk for a number of other health problems. A new study out of Brazil shows that postmenopausal women with breast cancer are at greater risk for developing heart disease. Results are published online in Menopause, the journal of The North American Menopause Society (NAMS).

Quantum music to my ears
It sounds like an old-school vinyl record, but the distinctive crackle in the music streamed into Chris Holloway's laboratory is atomic in origin. The group at the National Institute for Standards and Technology, Boulder, Colorado, spent a long six years finding a way to directly measure electric fields using atoms, so who can blame them for then having a little fun with their new technology?

Does greater immersion in virtual reality lead to a better experience?
Contrary to current industry trends to develop more immersive virtual reality systems, a new study found that a more immersive environment or the presence of real-world distractions could have surprising effects on a participant's recall, description of the virtual encounter, and how positive they feel about the experience. The design, results, and implications of this timely study are published in Cyberpsychology, Behavior, and Social Networking.
