Team validates potentially powerful new way to treat HER2-positive breast cancer
Scientists at Cold Spring Harbor Laboratory today reported a discovery that they hope will lead to the development of a powerful new way of treating an aggressive form of breast cancer called HER2-positive.

Advanced light
Whole beams, not just particles, can be entangled. This, plus anomalous dispersion in 'fast-light' materials, allows signals be to 'advanced' over signals travelling in vacuum, at least in a limited sense.

Stanford discovery could pave way to new treatment for rare jaw tumor
Researchers at the Stanford University School of Medicine have identified the mutations underlying a rare, understudied type of jaw tumor called ameloblastoma.

The Lancet Oncology: UN officials warn refugees are struggling to access cancer treatment
A study published in The Lancet Oncology journal reveals a high demand for costly cancer treatment among refugees from the recent conflicts in Iraq and Syria, with host countries struggling to find the money and the medicine to treat their new patients.

On alert: Stanford study identifies cell-cycle phase that primes stem cells for action
Resting, adult stem cells of many types of tissues enter a reversible 'alert' phase in response to a distant injury, according to a study in mice by researchers at the Stanford University School of Medicine.

Researchers map the epic evolution of a 'ring species'
An in-depth genomic analysis published today in Nature by University of British Columbia researchers reveals that the Greenish Warbler's genetic migration through central Asia involved periods of geographic separation and hybridization.

Buried fossil soils found to be awash in carbon
Soils that formed on the Earth's surface thousands of years ago and that are now deeply buried features of vanished landscapes have been found to be rich in carbon, adding a new dimension to our planet's carbon cycle.

Gene mutation found for aggressive form of pancreatic cancer
Researchers at the University of California, San Diego School of Medicine have identified a mutated gene common to adenosquamous carcinoma tumors -- the first known unique molecular signature for this rare, but particularly virulent, form of pancreatic cancer.

DNA nanotechnology places enzyme catalysis within an arm's length
Using molecules of DNA like an architectural scaffold, Arizona State University scientists, in collaboration with colleagues at the University of Michigan, have developed a 3-D artificial enzyme cascade that mimics an important biochemical pathway that could prove important for future biomedical and energy applications.

A new molecule for high-resolution cell imaging
Cells have their own tiny skeletons that are responsible for many important cellular functions.

Study identifies how signals trigger cancer cells to spread
Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a signaling pathway in cancer cells that controls their ability to invade nearby tissues in a finely orchestrated manner.

Mice with 'mohawks' help scientists link autism to 2 biological pathways in brain
'Aha' moments are rare in medical research, scientists say. As rare, they add, as finding mice with Mohawk-like hairstyles.

Sound and vision: Visual cortex processes auditory information too
'Seeing is believing,' so the idiom goes, but new research suggests vision also involves a bit of hearing too.

Novel drug target linked to insulin secretion and type 2 diabetes treatment
A signal that promotes insulin secretion and reduces hyperglycemia in a type 2 diabetes animal model is enhanced by the inhibition of a novel enzyme discovered by CHUM Research Centre and University of Montreal researchers.

Promising approach to slow brain degeneration in a model of Huntington's disease uncovered
Research presented by Dr. Lynn Raymond, from the University of British Columbia, shows that blocking a specific class of glutamate receptors can improve motor learning and coordination, and prevent cell death in animal models of Huntington's disease.

Scientists discover potential new target for cancer immunotherapy
Myeloid-derived suppressor cells are found abundantly in the microenvironment around tumors.

Climate change accelerates hybridization between native and invasive species of trout
Scientists have discovered that the rapid spread of hybridization between a native species and an invasive species of trout in the wild is strongly linked to changes in climate.
