New software continuously scrambles code to foil cyber attacks
New code-scrambling software developed at Columbia sets a deadline on malicious hackers, effectively closing the window of opportunity for so-called code-reuse attacks. The technique is described in a study presented earlier this month at the USENIX Symposium on Operating Systems and Design (OSDI) in Savannah, Ga.

Ant bridges connect shy tropical tree crowns
Tropical forest tree crowns don't quite touch, a phenomenon known as 'crown shyness.' To ants, shy canopy trees are like islands, and island biogeography rules apply. But connect the trees with vines, and the story changes.

High-fat diet disrupts brain maturation
The latest study by researchers from ETH Zurich and the University of Zurich suggests that excessive consumption of fatty foods could severely disrupt the development of the prefrontal cortex in the maturing brains of young people. This could potentially lead to cognitive defects in later adulthood in areas such as learning and memory, personality and impulse control.

New model reveals adaptations of world's most abundant ocean microbe
Researchers from the University of Hawai'i and Chalmers University of Technology developed a computer model which takes into account hundreds of genes, chemical reactions, and compounds required for the survival of Prochlorococcus, the most abundant photosynthetic microbe on the planet. They found that Prochlorococcus has made extensive alterations to its metabolism as a way to reduce its dependence on phosphorus, an element that is essential and often growth-limiting in the ocean.

For First Nations people, effects of European contact are recorded in the genome
A study of the genomes of 25 individuals who lived 1,000 to 6,000 years ago on the north coast of present-day British Columbia, and 25 of their descendants who still live in the region today, opens a new window on the catastrophic consequences of European colonization for indigenous peoples in that part of the world.

Kelp forests globally resilient, but may need local solutions to environmental threats
The first global assessment of marine kelp ecosystems shows that these critically important habitats have exhibited a surprising resilience to environmental impacts over the past 50 years, but they have a wide variability in long-term responses that will call for regional management efforts to help protect their health in the future.

Forest fires in Sierra Nevada driven by past land use
Forest fire activity in California's Sierra Nevada since 1600 has been influenced more by how humans used the land than by climate. For the years 1600 to 2015, the team found four periods, each lasting at least 55 years, where the frequency and extent of forest fires clearly differed from the time period before or after. The fire regimes corresponded to different types of human occupation and use of the land, rather than changes in climate.

Cosmic whistle packs a surprisingly energetic punch
For the first time, astronomers have discovered that mysterious 'cosmic whistles' known as fast radio bursts have a billion times more explosive power than previously known. The team is the first to detect gamma rays -- the most powerful type of electromagnetic energy -- in these fast radio bursts, which previously had been detected exclusively in radio waves -- the least powerful type of electromagnetic energy

Study to explore detection of learning disabilities through physical movement
An Indiana University physicist and neuroscientist who studies how physical movement can be used to detect autism in children and adults has received support from the National Science Foundation. The $750,000 NSF grant to IU scientist Jorge V. Josť and collaborators will be used to apply analytical methods pioneered at IU and Rutgers University toward diagnosing, and possibly treating, a wider range of learning disabilities.

Making the most of clean energy
Recent years have witnessed the rise of an economic revolution -- the so-called sharing economy -- across many facets of business. Could the electricity marketplace be next? Boris Defourny, assistant professor of industrial and systems engineering at Lehigh University, seeks to understand how this could take shape. He's recently won a grant from the NSF to understand how to optimize the integration of renewable energy for usage across the power grid.
