In a paper published in NANO, a group of researchers from Hebei University of Technology, Tianjin, China have discovered an effective way to remove heavy metal Cadmium(II) from wastewater. This utilizes the surface-initiated atom-transfer radical polymerization (SI-ATRP) method to graft poly (tert-butyl acrylate) PtBA from the ultrathin pore wall of inverse opal (IO) SiO2.
Enantioselectivity plays an important role in the pharmacological and toxicological processes of chiral drugs.
In chiral drug synthesis that uses bioorthogonal chemistry within complex biological milieu, asymmetric transfer hydrogenation (ATH), which utilizes safe hydrogen donors instead of high pressure H2, has been gaining popularity and has been performed in living cells.
CHAPEL HILL, N.C. (June 26,2020) -- It's entirely reasonable during a pandemic to feel more stressed, anxious, lonely and depressed than usual. Yet, despite the circumstances, some people are doing OK. Some people continue to feel love for others, gratitude for what they have and joy in the small things.
CRISPR-Cas9 has become one of the most convenient and effective biotechnology tools used to cut specific DNA sequences. Starting from Streptococcus pyogenes Cas9 (SpCas9), a multitude of variants have been engineered and employed for experiments worldwide. Although all these systems are targeting and cleaving a specific DNA sequence, they also exhibit relatively high off-target activities with potentially harmful effects.
Tsukuba, Japan - It is no secret that DNA, in the form of chromosomes, is the building block of life. Incorrect distribution of chromosomes during cell division can have disastrous consequences. Unbalanced chromosome copy, or aneuploidy, is a hallmark of tumors and affects development and survival in all organisms, including humans.
Japan -- Symmetry and asymmetry are fundamental properties of nature. Seen from above, butterflies have left-right symmetry, while male fiddler crabs show dramatic asymmetry. This is also the case for the fundamental units of life: cells. They control the symmetry of their internal structures to regulate all biological functions.
Publishing in Nature Communications, a team led by Kyoto University's Hakubi Center for Advanced Research has announced the development of an artificial cell that brings to light the dynamics that govern each cell's internal symmetry.
Using radar commonly deployed to track speeders and fastballs, researchers have developed an automated system that will allow cars to peer around corners and spot oncoming traffic and pedestrians.
A team of researchers at the Department of Energy's Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease -- the enzyme that enables the virus to reproduce.
It is not unusual to come across headlines about pollution or global warming and find that they reach different conclusions depending upon the data source.
Researchers at Washington University in St. Louis used a harmonized approach, incorporating data from multiple satellites and ground monitors with computer modeling to compile a comprehensive, consistent map of pollution across the globe. Their data spans 1998-2018, providing a current picture of the state of the world's air quality that reveals some surprises, both for better and for worse.
A new study by researchers at the Johns Hopkins Bloomberg School of Public Health found that the odds of a fatal opioid overdose were 1.5 times higher for individuals with one to two visits to the emergency department for any medical issue than for people with no hospital visits. The researchers also found that individuals with a hospital visit where opioid use disorder was addressed were 2.9 times more likely to die from an overdose over the coming year, compared with other people.
CORVALLIS, Ore. - Suspended, rotating devices known as "flappers" may be the key to fewer birds flying into power lines, a study by Oregon State University suggests.
The findings by researchers in OSU's College of Agricultural Sciences are important because around the globe both the number of power lines and concern over bird fatalities are on the rise.
Despite reports that children and young people may be less likely to get coronavirus disease 2019 (COVID-19) than older adults, there may be substantial indirect adverse effects of the disease on their physical and mental health, according to an analysis in CMAJ (Canadian Medical Association Journal). http://www.cmaj.ca/lookup/doi/10.1503/cmaj.201008
EL PASO, Texas - A research team from The University of Texas at El Paso has made strides in understanding how memories are formed through the brain mechanisms of fruit flies, findings that could enhance our understanding of brain disorders such as post-traumatic stress disorder and substance addiction, according to an article published in the highly renowned Journal of Neuroscience.
Exposure to wildfire smoke affects the body's respiratory and cardiovascular systems almost immediately, according to new research from the University of British Columbia's School of Population and Public Health.
RESEARCH TRIANGLE PARK, N.C. -- Two U.S. Army research projects advance quantum networking, which will likely play a key role in future battlefield operations.
