Peri-implantitis, a condition where tissue and bone around dental implants becomes infected, besets roughly one-quarter of dental implant patients, and currently there's no reliable way to assess how patients will respond to treatment of this condition.
To that end, a team led by the University of Michigan School of Dentistry developed a machine learning algorithm, a form of artificial intelligence, to assess an individual patient's risk of regenerative outcomes after surgical treatments of peri-implantitis.
An international research team led by the University of Cologne has succeeded for the first time in connecting several atomically precise nanoribbons made of graphene, a modification of carbon, to form complex structures. The scientists have synthesized and spectroscopically characterized nanoribbon heterojunctions. They then were able to integrate the heterojunctions into an electronic component. In this way, they have created a novel sensor that is highly sensitive to atoms and molecules.
By Karina Ninni | Agência FAPESP – A study of 92 adolescents conducted in Brazil suggests girls are more likely than boys to develop metabolic alterations associated with obesity, such as high blood pressure and excessive blood levels of cholesterol and triglycerides (dyslipidemia).
Asian students and faculty have long been a cornerstone of science in the U.S., drawn by the promise of collaboration and cutting-edge research. However, the Asian community is facing increased racist attacks and scrutiny from the government. A cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, explores how Asian scientists are reassessing their futures in the U.S.
TAMPA, Fla. -- Melanocytic nevi, or moles, are nonmalignant growths that arise from pigment producing cells of the skin. They are mostly found in sun-exposed areas; however, they also can be found in sun-protected areas, such as the palms, soles of feet and nail beds, where they are known as acral nevi. While the mutation profile of nevi in sun-exposed areas is well understood, less is known about the genes that are commonly mutated in acral nevi. And while a subset of melanoma of sun-exposed skin arises in nevi, the link between nevi and melanoma in acral skin is poorly understood.
URBANA, Ill. - Gut health is having a moment, with sales of fermented foods such as kefir, kombucha, and kimchi steadily on the rise. The benefits of "good bacteria" in fermented foods and supplements go well beyond the gut, moderating immune responses, heart health, weight, and even mood. But do products hold up to the claims on their labels?
East Hanover, NJ. May 12, 2021. A team of specialists in regenerative rehabilitation conducted a successful pilot study investigating micro-fragmented adipose tissue (MFAT) injection for rotator cuff disease in wheelchair users with spinal cord injury. They demonstrated that MFAT injection has lasting pain-relief effects.
Earthworms improve the soil by aerating it, breaking down organic matter and mineralizing nutrients. Now, researchers reporting in ACS' Environmental Science & Technology have dug up another possible role: reducing the number and relative abundance of antibiotic-resistance genes (ARGs) in soils from diverse ecosystems. These results imply that earthworms could be a natural, sustainable solution to addressing the global issue of antibiotic resistance, the researchers say.
The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity.
A team led by University of Michigan researchers has developed a material that's at least twice as "magnetostrictive" and far less costly than other materials in its class. In addition to computing, it could also lead to better magnetic sensors for medical and security devices.
Lancaster scientists have demonstrated that other physicists' recent "discovery" of the field effect in superconductors is nothing but hot electrons after all.
A team of scientists in the Lancaster Physics Department have found new and compelling evidence that the observation of the field effect in superconducting metals by another group can be explained by a simple mechanism involving the injection of the electrons, without the need for novel physics.
COLUMBUS, Ohio - Kindergartners from low-income families spent more than six hours a day in front of screens during two early months of the COVID-19 pandemic, a small Ohio study suggests.
That is nearly double the screen time found before the pandemic in similar children, according to other research.
Caregivers from low-income households may have faced more difficulties than those from more advantaged families in managing the time their children spent watching TV and using computers, phones and tablets when child care was shut down, according to the researchers.
Researchers have recently extracted the proton mass radius from the experimental data.
A research group at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) presented an analysis of the proton mass radius in Physical Review D on May 11. The proton mass radius is determined to be 0.67 ± 0.03 femtometers, which is obviously smaller than the charge radius of the proton.
Atoms are the basic building blocks for all materials. To tailor functional properties, it is essential to accurately determine their atomic structures. KAIST researchers observed the 3D atomic structure of a nanoparticle at the atom level via neural network-assisted atomic electron tomography.
New guidelines for coral reef restoration aiming to reduce the risk of flooding in tropical coastal communities have been set out in a new study that simulated the behavior of ocean waves travelling over and beyond a range of coral reef structures. Published in Frontiers in Marine Science, these guidelines hope to optimize restoration efforts not only for the benefit of the ecosystem, but also to protect the coast and people living on it.
A scientist from HSE University has developed an image recognition algorithm that works 40% faster than analogues. It can speed up real-time processing of video-based image recognition systems. The results of the study have been published in the journal Information Sciences.
