SPOKANE, Wash. - New clues as to why night shift workers are at increased risk of developing certain types of cancer are presented in a new study conducted at Washington State University Health Sciences Spokane.
The Lancet today published the latest Series on Maternal and Child Undernutrition Progress, including three new papers that build upon findings from the previous 2008 and 2013 Series, which established an evidence-based global agenda for tackling undernutrition over the past decade.
Professor Byoungwoo Kang develops a high-density cathode material through controlling local structures of the Li-rich layered materials.
Researchers in Korea have developed a high-capacity cathode material that can be stably charged and discharged for hundreds of cycles without using the expensive cobalt (Co) metal. The day is fast approaching when electric vehicles can drive long distances with Li- ion batteries.
ORLANDO, March 5, 2021 - Nuisance flooding has increased on U.S. coasts in recent decades due to sea level rise, and new research co-authored by the University of Central Florida uncovered an additional reason for its added frequency.
In a study appearing today in the journal Science Advances, researchers show that higher local tide ranges, most likely from human alterations to coastal areas and estuaries, has increased the number of nuisance flooding days in many coastal locations in the U.S.
Researchers at Scripps Institution of Oceanography at UC San Diego examining 14 years of hospital admissions data conclude that the fine particles in wildfire smoke can be several times more harmful to human respiratory health than particulate matter from other sources such as car exhaust. While this distinction has been previously identified in laboratory experiments, the new study confirms it at the population level.
Quantitative real-time polymerase chain reaction (qPCR) is the most widely used diagnostic method to detect RNA viruses such as SARS-CoV-2. However, it requires expensive laboratory equipment and global shortages of reagents for RNA purification has increased the need to find simple but reliable alternatives. One alternative to the qPCR technology is RT-LAMP (reverse transcription loop-mediated isothermal amplification). This test amplifies the desired target sequences of the virus at a constant temperature, using minimal equipment compared to qPCR.
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) found large quantities of previously undetectable compounds from the family of chemicals known as PFAS in six watersheds on Cape Cod using a new method to quantify and identify PFAS compounds. Exposures to some PFAS, widely used for their ability to repel heat, water, and oil, are linked to a range of health risks including cancer, immune suppression, diabetes, and low infant birth weight.
Tsukuba, Japan and Warsaw, Poland - Scientists from the University of Tsukuba and a scientist from the Institute of High Pressure Physics detected and mapped the electronic spins moving in a working transistor made of molybdenum disulfide. This research may lead to much faster computers that take advantage of the natural magnetism of electrons, as opposed to just their charge.
Kanazawa, Japan - Non-rigid point set registration is the process of finding a spatial transformation that aligns two shapes represented as a set of data points. It has extensive applications in areas such as autonomous driving, medical imaging, and robotic manipulation. Now, a method has been developed to speed up this procedure.
In a study published in IEEE Transactions on Pattern Analysis and Machine Intelligence, a researcher from Kanazawa University has demonstrated a technique that reduces the computing time for non-rigid point set registration relative to other approaches.
Semiconductor materials play an indispensable role in our modern information-oriented society. For reliable performance of semiconductor devices, these materials need to have superior mechanical properties: they must be strong as well as resistant to fracture, despite being rich in nanoscale structures.
If you stretch an elastic band, it becomes thinner - a physical behavior that applies to most "common" materials. Since the 20th century, an opposite behavior has been known in materials research: The so-called auxetic (from ancient Greek auxetos, meaning 'stretchable') materials expand in the direction orthogonal to the strain. Likewise, they shrink when they are compressed. Scientifically, they are characterized by a negative Poisson's ratio. Probably the best known and oldest application of unusual Poisson's ratios is the bottle cork, which has a Poisson's ratio of zero.
SMU Office of Research & Tech Transfer - For most of human history, populations across the world lived in low-density, rural settings. Over the past few centuries, however, this changed dramatically with the trend of urbanisation. Today, more than four billion people live in urban settings worldwide; by 2050, about two thirds of the world's population are expected to live in cities.
As the source of most of the water we drink and a place where we often go to recreate and enjoy nature, streams represent a crucial point-of-contact between human beings and the environment.
Now researchers in the College of Natural Resources and Environment and the Department of Biological Systems Engineering are using stream quality data to find new insights into the interactions between the health of our natural spaces and human well-being.
In recent years, therapeutic antibodies have transformed the treatment of cancer and autoimmune diseases. Now, researchers at Lund University in Sweden have developed a new, efficient method based on the genetic scissors CRISPR-Cas9, that facilitates antibody development. The discovery is published in Nature Communications.
Anyone who has owned a smartphone for over a year is most likely aware that its built-in lithium (Li)-ion battery does not hold as much charge as when the device was new. The degradation of Li-ion batteries is a serious issue that greatly limits the useful life of portable electronic devices, indirectly causing huge amounts of pollution and economic losses. In addition to this, the fact that Li-ion batteries are not very durable is a massive roadblock for the market of electric vehicles and renewable energy harvesting.
