The blood-brain barrier is a layer of cells that covers the blood vessels in the brain and regulates the entry of molecules from the blood into the brain. Increases in blood-brain barrier "permeability," or the extent to which molecules leak through, are observed in several neurological and psychiatric disorders; therefore, understanding the regulation of blood-brain barrier permeability is crucial for developing better therapies for such disorders.
Highly functional and free-form displays are critical components to complete the technological prowess of wearable electronics, robotics, and human-machine interfaces.
A KAIST team created stretchable OLEDs (Organic Light-Emitting Diodes) that are compliant and maintain their performance under high-strain deformation. Their stress-relief substrates have a unique structure and utilize pillar arrays to reduce the stress on the active areas of devices when strain is applied.
Tsukuba City, Japan - Asteroid strikes upset the environment and provide clues via the elements they leave behind. Now, University of Tsukuba researchers have linked elements that are enriched in the Cretaceous-Paleogene (KPg) boundary clays from Stevns Klint, Denmark, to the impact of the asteroid that produced the Chicxulub crater at the Yucatán Peninsula, Mexico. This corresponds to one of the "Big Five" mass extinctions, which occurred at the KPg boundary at the end of the Cretaceous, 66 million years ago.
A group led by researchers from Kobe University has illuminated clinical factors that are related to the occurrence of congenital cytomegalovirus (CMV) infection in newborns. They revealed for the first time in the world that fever or cold-like symptoms (including cough, sore throat and runny nose) during pregnancy, and threatened miscarriage or threatened premature labor (*1) in the second trimester (14-27 gestational weeks) were associated with CMV infection in newborns.
Proteins denature, or "cook" in heat, irreversibly changing their structure, like how an egg boils or a slab of sirloin turns to steak. This prevents proteins from being used in applications where they would need to withstand heat. Scientists have had high expectations for proteins to be used in nanotechnology and synthetic biology.
The size of glass used for serving wine can influence the amount of wine drunk, suggests new research from the University of Cambridge, funded by the National Institute of Health Research (NIHR). The study found that when restaurants served wine in 370ml rather than 300ml glasses they sold more wine, and tended to sell less when they used 250ml glasses. These effects were not seen in bars.
The 2013 Universal Credit welfare reform appears to have led to an increase in the prevalence of psychological distress among unemployed recipients, according to a nationally representative study following more than 52,000 working-age individuals from England, Wales, and Scotland over nine years between 2009-2018, published as part of an issue of The Lancet Public Health journal on income and health.
EVANSTON, Ill. -- If the world is using more and more data, then it must be using more and more energy, right? Not so, says a comprehensive new analysis.
Researchers at Northwestern University, Lawrence Berkeley National Laboratory and Koomey Analytics have developed the most detailed model to date of global data center energy use. With this model, the researchers found that, although demand for data has increased rapidly, massive efficiency gains by data centers have kept energy use roughly flat over the past decade.
The perception of speech and music - two of the most uniquely human uses of sound - is enabled by specialized neural systems in different brain hemispheres adapted to respond differently to specific features in the acoustic structure of the song, a new study reports. Though it's been known for decades that the two hemispheres of our brain respond to speech and music differently, this study used a unique approach to reveal why this specialization exists, showing it depends on the type of acoustical information in the stimulus.
You can delay irrigating the lawn or washing the car all you want, but to really make a big dent in water savings we need to stop water waste long before the precious resource ever reaches our taps.
An estimated 20 to 50 percent of water is lost to leaks in North America's supply system - a major issue as utilities contend with how to sustain a growing population in an era of water scarcity.
Irvine, Calif. - February 27, 2020 - Human fingers are sculpted from a primitive pad-like structure during embryonic development. Sometimes, this process goes awry and babies are born with fused fingers or toes. A new study from the University of California, Irvine reveals new factors involved in the congenital malformation called syndactyly.
Researchers at Oak Ridge National Laboratory and the University of Tennessee achieved a rare look at the inner workings of polymer self-assembly at an oil-water interface to advance materials for neuromorphic computing and bio-inspired technologies.
Results published in the Journal of the American Chemical Society provide new insights on the way molecules pack and order themselves into "tunable" interfaces, monolayer thick surfaces with structures that can be modified for specific functionalities.
Two tree species native to the Northeast have been found to be structurally sound for use in cross-laminated timber (CLT) - a revolutionary new type of building material with sought-after sustainability characteristics, according to research by a University of Massachusetts Amherst timber engineer.
The study of a rare genetic disease has enabled a team led by Ludwig-Maximilians-Universitaet (LMU) in Munich´s Christoph Klein to uncover the role of a membrane-associated protein in the development and function of human T cells.
While older adults, defined as those 65 and older, make up the largest percentage of cancer patients and survivors, this group is not adequately represented in clinical trials, research at the University of Cincinnati has shown.
