Stanford University computer science graduate student Mackenzie Leake has been quilting since age 10, but she never imagined the craft would be the focus of her doctoral dissertation. Included in that work is new prototype software that can facilitate pattern-making for a form of quilting called foundation paper piecing, which involves using a backing made of foundation paper to lay out and sew a quilted design.
BAR HARBOR, MAINE — Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.
The photochemistry of the future will spring up human industry without smoke, and bring a brighter civilization based on the utilization of solar energy instead of fossil energy. Photochemistry has been used in controlling many reaction processes, especially for the challenging reactions containing selective C-H activation and C-C coupling in chemical synthesis.
A catastrophic drop in atmospheric ozone levels around the tropics is likely to have contributed to a bottleneck in the human population around 60 to 100,000 years ago, an international research team has suggested. The ozone loss, triggered by the eruption of the Toba supervolcano located in present-day Indonesia, might solve an evolutionary puzzle that scientists have been debating for decades.
Researchers from North Carolina State University have developed a new state-of-the-art method for controlling how artificial intelligence (AI) systems create images. The work has applications for fields from autonomous robotics to AI training.
LAWRENCE -- In the early days of COVID-19 vaccine development, a new social media platform provided a place for like-minded people to discuss vaccines, share misinformation and speculate about the motivations for its development. A new study from the University of Kansas shows people flocked to Parler to discuss the vaccines in an echo chamber-type environment, and those conversations can shed light about how to communicate about vaccine efficacy during health crises.
BUFFALO, N.Y. -- For many people, the need to go grocery shopping is met with a sigh, or an "ugh." It's generally not considered to be an enjoyable experience.
For moms who shop using WIC benefits, it can be a downright awful experience, one that's often made worse by difficulty finding eligible products and dealing with a lengthy checkout process. Add kids in tow and it's enough for many moms to forego re-enrolling in the Special Supplemental Nutrition Program for Women, Infants and Children, commonly known as WIC.
CHAPEL HILL, North Carolina--Researchers have discovered a gene, OTUD7A, that impacts the development of Ewing sarcoma, a bone cancer that occurs mainly in children. They have also identified a compound that shows potential to block OTUD7A protein activity. The finding, by scientists at the University of North Carolina and the Lineberger Comprehensive Cancer Center, appeared online June 1, 2021, in Advanced Science.
The genetic material of most organisms is carried by DNA, a complex organic molecule. DNA is very long -- for humans, the molecule is estimated to be about 2 m in length. In cells, DNA occurs in a densely packed form, with strands of the molecule coiled up in a complicated but efficient space-filling way. A key role in DNA's compactification is played by histones, structural-support proteins around which a part of a DNA molecule can wrap. The DNA-histone wrapping process is reversible -- the two molecules can unwrap and rewrap -- but little is known about the mechanisms at play.
The Water Oxidation Reaction (WOR) is one of the most important reactions on the planet since it is the source of nearly all the atmosphere's oxygen. Understanding its intricacies can hold the key to improve the efficiency of the reaction. Unfortunately, the reaction's mechanisms are complex and the intermediates highly unstable, thus making their isolation and characterisation extremely challenging. To overcome this, scientists are using molecular catalysts as models to understand the fundamental aspects of water oxidation - particularly the oxygen-oxygen bond-forming reaction.
Professor YAO Huajian's research group from the School of Earth and Space Sciences of the University of Science and Technology of China (USTC), in cooperation with Dr. Piero Poli from Grenoble-Alpes University of France, combined the unique resolution reflected body waves (P410P and P660P) retrieved from ambient noise interferometry with mineral physics modeling, to shed new light on transition zone physics. Relevant work was published in Nature Communications.
Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change, according to new research published in Science Advances.
A study examining Japanese schools' hands-off approach when children fight showed it could create opportunities for autonomy and encourage ownership of solutions, suggesting a new strategy in handling kids squabbles in other countries.
The work was conducted under the auspices of the Russian Foundation for Basic Research and organizations-participants of the BRICS framework program in science, technology and innovation; the grant title is "Nanosized peptide-based biomaterials for photodynamic diagnostics of tumors".
COLUMBUS, Ohio - If you've watched a slasher movie, you've probably been exposed to the final girl trope - a closing scene of a white, suburban teenage girl who triumphed over a threatening monster and lived to tell the tale.
But her story doesn't stop there - in some ways, a whole new life, overshadowed by trauma, has only just begun, Ohio State University graduate student Morgan Podraza posits in an article published in the journal Horror Studies.
