Ancient Denisovan DNA excavated in modern Pacific Islanders
Archaic Denisovan and Neanderthal DNA that persists in modern Pacific islanders of Melanesia, far from the Siberian cave where Denisovan fossils have been found, is a source of information about early human history. Equally informative are genome regions where DNA from extinct, human-like species has vanished and been replaced with sequences unique to people. These large regions have genes for brain development, language and brain cell signalling. Retained archaic DNA in human genomes may confer infection-fighting advantages.

Future brain therapies for Parkinson's possible with stem cell bioengineering innovation
Scientists at Rutgers and Stanford universities have created a new technology that could someday help treat Parkinson's disease and other devastating brain-related conditions that affect millions of people. The technology -- a major innovation -- involves converting adult tissue-derived stem cells into human neurons on 3-D 'scaffolds,' or tiny islands, of fibers, said Prabhas V. Moghe, a distinguished professor at Rutgers.

For first time, scientists use CRISPR-Cas9 to target RNA in live cells
Scientists have long sought an efficient method for targeting RNA -- intermediary genetic material that carries the genetic code from the cell's nucleus to protein-making machinery -- in living cells. Researchers at University of California, San Diego School of Medicine have now achieved this by applying the popular DNA-editing technique CRISPR-Cas9 to RNA. The study is published March 17, 2016 in Cell.

Viruses 'piggyback' on host microbes' success
It has generally been assumed that in a growing population of microbes, viruses also multiply and kill their hosts, keeping the microbial population in check. A recent study of virus-host dynamics near coral reefs led by SDSU virologists suggests that, under certain conditions, viruses can change their infection strategy. As potential host microbes become more numerous, some viruses forego rapid replication and opt instead to reside peaceably inside their host, thereby reducing their the viruses' numbers.

Wetland enhancement in Midwest could help reduce catastrophic floods of the future
Restoration of wetlands in the Midwest could significantly reduce peak river flows during floods -- not only now, but also in the future if heavy rains continue to increase in intensity, as climate models predict. New financial models and flood management policies may be needed to actually accomplish this.

Adolescent female pandas not the demure homebodies once thought
In the furry animal world, it's the boys approaching adulthood who tend to start to wander to seek their fortune. Which usually means a mate. Girls tend to stay closer to the home range. But giant pandas, once again, buck a mammal trend.

Study: How more R&D funding can hasten green revolution
In a newly published paper, MIT Prof. Daron Acemoglu and three colleagues present a uniquely detailed model of the dynamics of innovation in the energy industry. In so doing, they indicate how supporting clean energy R&D, not just a carbon tax, might be the best way to help clean energy technologies compete with traditional forms of energy.

Pigeon foot feather genes identified
University of Utah scientists identified two genes that make some pigeon breeds develop feathered feet known as muffs, while others have scaled feet. The same or similar genes might explain scaled feet in chickens and other birds, and provide insight into how some dinosaurs got feathers before they evolved into birds.

Scientists create painless patch of insulin-producing beta cells to control diabetes
For decades, researchers have tried to duplicate the function of beta cells, which don't work properly in patients with diabetes. Now, researchers have devised another option: a synthetic patch filled with natural beta cells that can secrete doses of insulin to control blood sugar levels on demand.

New 'machine unlearning' technique wipes out unwanted data quickly and completely
Researchers from Lehigh University and Columbia University are pioneering a novel approach to making computer learning systems forget. Called 'machine unlearning,' the method is based on the fact that most learning systems can be converted into a form that can be updated incrementally without costly retraining from scratch. This makes it easier and faster for systems to 'unlearn' data -- important for thwarting and recovering from attacks and protecting privacy.

Carbon from land played a role during last deglaciation
As the Earth emerged from its last ice age several thousand years ago, atmospheric carbon dioxide increased and further warmed the planet. Scientists have long speculated that the primary source of this CO2 was from the deep ocean around Antarctica, though it has been difficult to prove. A study published this week confirmed that theory.
