Over the past 50 years, nearly 4 in 10 peace agreements have failed within five years of signing. New research shows that when international partners help implement an accord, the odds improve—and the deeper their engagement, the better.
A research team led by Prof. Hao Ning of the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Anhui University and the University of Science and Technology of China, has identified two distinct types of unusual low-energy quasiparticle states in the kagome superconductor CsV3Sb5 using single-atom impurities as local "quantum probes" combined with scanning tunneling spectroscopy.
You're in the lab analyzing Martian regolith samples within your cozy Mars habitat serving on the fifth human mission to Mars. The power within the habitat has been flowing flawlessly thanks to the MARS-MES (Mars Atmospheric Resource & Multimodal Energy System), including the general habitat lighting, science lab, sleeping quarters, exercise equipment, the virtual reality headsets the crew use for rest & relaxation, oxygen and fuel generation, and water. All this from converting the Martian atmosphere into workable electricity.
The rising popularity of urban beekeeping has raised concerns about honeybee well-being and the impact they might have on wild bee populations in cities. A collaborative study by beekeepers, political stakeholders and research institutions, including researchers from the Technical University of Munich (TUM) has resulted in the "Urban Bee Concept," which includes measures to foster co-existence between honeybees and wild bees in cities. The study is published in the journal People and Nature.
Microplastics are now widely distributed throughout the environment—in water, in the air, in the soil and even inside living organisms, including marine life. However, most studies to date have focused on adult fish, including those used for human consumption. The history of these microplastics, however, remained unknown. It was not clear exactly when this contamination begins throughout the life cycle.
Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new research from McMaster University reveals a surprising twist: the most common planets in our galaxy don't exist around the most common stars.
Seoul National University College of Engineering announced that a research team has developed a behavior-based safety assessment system capable of measuring construction workers' ability to perceive risks and respond appropriately to them. The team was led by Prof. Changbum R. Ahn of the Department of Architecture and Architectural Engineering in collaboration with Prof. Jeongmi Lee's team at the Graduate School of Culture Technology at KAIST.
Each year, 20 million people are diagnosed with cancer. Various organs can be affected, and cancer types sometimes differ greatly at the cellular and molecular level. In about half of all cases, however, the protein p53 is mutated. Known as the "guardian of the genome," it plays a central tumor suppressor role: In healthy cells, it ensures that DNA damage is detected and repaired. If this is not successful, the affected cell is selectively eliminated through apoptosis—an important protection against cancer. Conversely, cells can often only develop into tumor cells when the protein p53 is inactivated by a mutation. In many cases, it becomes unstable as a result of the mutation and loses its functional structure.
Our current fascination with high-protein foods means plant-based protein now shows up in many food products. But rather than growing plants just for their protein, researchers wondered if edible flowers—like pot marigolds that are usually composted or thrown away once they're past their prime—could be a new, sustainable plant-based protein source. So, they measured the protein content and composition of dried marigolds, and they report the results in ACS Food Science & Technology.
Chemists and computer scientists tapped AI to find new disinfectants to combat the growing threat of dangerous "superbugs." Their computational-experimental framework for developing quaternary ammonium compounds, or QACs, to kill bacteria yielded 11 new QACs that show activity against antimicrobial-resistant bacteria.
