Terpen-tales: The mystery behind the unique fragrance of the lovely lavender
Scientists from China have sequenced and analyzed the genome of lavender to provide insights into what causes its distinct aroma. Their findings shed light into the evolution of this uniquely fragrant plant, which could pave the way for creating improved lavender varieties besides adding to existing knowledge on the evolution, phytochemistry, and ecology of Lamiaceae, the plant family to which lavender belongs.

New technology enables rapid sequencing of entire genomes of plant pathogens
Next-generation sequencing technology has made it easier than ever for quick diagnosis of plant diseases. "It's really exciting to see how sequencing technologies have evolved and how this new technology facilitates sequencing of entire genomes in such a short amount of time," said Yazmín Rivera, a plant pathologist with the United States Department of Agriculture's Plant Protection and Quarantine program, who recently published a research paper on the efficacy of Oxford Nanopore Technologies protocols.

Heart attack recovery aided by injecting heart muscle cells that overexpress cyclin D2
In a large-animal study, researchers have shown that heart attack recovery is aided by injection of heart muscle cells derived from human induced pluripotent stem cell line, or hiPSCs, that overexpress cyclin D2. This research, published in the journal Circulation, used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has higher clinical relevance to human disease, compared to studies in mice.

New cyanobacteria species spotlights early life
Cyanobacteria first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms. Led by BTI faculty member Fay-Wei Li, researchers have discovered a new species of cyanobacteria, Anthocerotibacter panamensis, which could help illuminate how photosynthesis evolved to create the world as we know it.

Scientists rewrite the genesis of mosquito-borne viruses
Better designed vaccines for insect-spread viruses like dengue and Zika are likely after researchers discovered models of immature flavivirus particles were originally misinterpreted.Researchers from The University of Queensland and Monash University have now determined the first complete 3D molecular structure of the immature flavivirus, revealing an unexpected organization.

Glaciologists measure, model hard glacier beds, write slip law to estimate glacier speeds
Researchers measured rock glacier beds to create high-resolution digital models they used to study how glaciers move along their bedrock bases. The resulting glacier "slip law" can be used by other researchers to better estimate how quickly ice sheets flow into oceans, drop their ice and raise sea levels.

New research shows: Antoni van Leeuwenhoek led rivals astray
A microscope used by Antoni van Leeuwenhoek to conduct pioneering research contains a surprisingly ordinary lens, as new research by Rijksmuseum Boerhaave Leiden and TU Delft shows. It is a remarkable finding, because Van Leeuwenhoek (1632-1723) led other scientists to believe that his instruments were exceptional. Consequently, there has been speculation about his method for making lenses for more than three centuries. The results of this study were published in Science Advances on May 14.
