Some 40 years since CT scans first revealed abnormalities in the brains of schizophrenia patients, international scientists say the disorder is a systemic disruption to the brain's entire communication system.
The study, published in the Nature journal Molecular Psychiatry on Oct.17, sets the stage for future research on the debilitating mental illness that, according to the World Health Organization, affects more than 21 million people worldwide.
Researchers aiming to understand why autism spectrum disorders (ASD) are more common in boys have discovered differences in a brain signaling pathway involved in reward learning and motivation that make male mice more vulnerable to an autism-causing genetic glitch.
For the first time ever, using mass spectrometry, researchers have successfully read several bytes of data recorded on a molecular scale using synthetic polymers. Their work, conducted under the aegis of the Institut Charles Sadron (CNRS) in Strasbourg and the Institute of Radical Chemistry (CNRS / Aix-Marseille University), sets a new benchmark for the amount of data -- stored as a sequence of molecular units (monomers) -- that may be read using this routine method. It also sets the stage for data storage on a scale 100 times smaller than that of current hard drives.
Scientists have used cutting-edge DNA technology and museum samples collected over the past two centuries to reveal a new species of diving beetle living in streams around the Mediterranean.
Meladema coriacea is among Europe's largest water beetles and has been considered common across the south of the continent and in North Africa since the early 19th century.
But academics from the University of Plymouth and the Institute of Evolutionary Biology in Barcelona have now shown what was long thought to be one common species is actually two.
OAK BROOK, Ill. - A machine learning tool can help identify which high-risk breast lesions are likely to become cancerous, according to a new study appearing online in the journal Radiology. Researchers said the technology has the potential to reduce unnecessary surgeries.
Philadelphia, PA, October 17, 2017 - Diffuse large B-cell lymphoma (DLBCL) is an aggressive cancer and the most frequently diagnosed non-Hodgkin lymphoma worldwide (nearly 40% of cases). Recent advancements indicate that both the prognosis and choice of treatment of DLBCL may depend on identifying its molecular subtype.
BIRMINGHAM, Ala. - University of Alabama at Birmingham biomedical engineers report a significant advance in efforts to repair a damaged heart after a heart attack, using grafted heart-muscle cells to create a repair patch. The key was overexpressing a gene that activates the cell-cycle of the grafted muscle cells, so they grow and divide more than control grafted cells.
Scientists have invented a way to morph liquid metal into physical shapes.
Researchers at the University of Sussex and Swansea University have applied electrical charges to manipulate liquid metal into 2D shapes such as letters and a heart.
The team says the findings represent an "extremely promising" new class of materials that can be programmed to seamlessly change shape. This open up new possibilities in 'soft robotics' and shape-changing displays, the researcher say.
An engineered string of micronwide beads may take up the slack where computer modeling fails researchers who study the bending, folding and other movements of polymers or biomolecules like actin and DNA.
Rice University chemical and biomolecular engineer Sibani Lisa Biswal and her students -- lead author Steve Kuei, a graduate student, and co-author Burke Garza, an undergraduate -- created strings of polystyrene beads enhanced with iron to magnetize them and with streptavidin, a natural protein that serves as a springy linker between them.
The next time you come across a knotted jumble of rope or wire or yarn, ponder this: The natural tendency for things to tangle may help explain the three-dimensional nature of the universe and how it formed.
