From engineered pandemics to city-toppling cyber attacks to nuclear annihilation, life on Earth could radically change, and soon. Scientists will forecast the fate of the planet at a press conference during the 2021 APS April Meeting.
Large-scale supercomputer simulations at the atomic level show that the dominant G form variant of the COVID-19-causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, compared to other variants.
A new publication offers a comprehensive guide to help plant scientists communicate their work to the world. An Iowa State University scientist who contributed to the multi-institutional effort says it's critical that plant scientists emphasize outreach to make sure plant science is able to meet the demands of climate change and population growth.
Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.
Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The results are published in the journal Chemical Communications (ChemComm).
Underground pipelines that transport oil and gas are very important engineering communications worldwide. Some of these underground communications are built and operated in earthquake-prone areas. The research shows that current methods used for calculating stress received by the underground pipelines during an earthquake are incorrect.
Researchers at the Human Interface Technology Lab New Zealand at the University of Canterbury compared the effectiveness of virtual humans to real ones for helping people practice leadership skills. They found that virtual humans with realistic characteristics can be equally effective in these types of training scenarios. This was especially the case in mixed reality settings, which blend real and digital worlds together, providing an anchor to reality that appeared to positively impact performance and engagement.
Generation of super-resolved optical needle and multifocal array using graphene oxide metalenses In a new publication from Opto-Electronic Advances; DOI https://doi.org/10.29026/oea.2021.200031, Researchers led by Professor Baohua Jia at Swinburne University of Technology, Victoria, Australia, Professor Cheng-Wei Qiu at National University of Singapore, Singapore and Professor Tian Lan at Beijing Institute of Technology, Beijing, China considered the generation of super-resolved optical needle and multifocal array using graphene oxide metalenses.
The researchers have discovered that USP7 inhibitors -under development by several pharmaceutical companies for the treatment of cancer- trigger a premature activation of cell cycle proteins, leading to uncontrolled cancer cell division and death. * The paper rejects the premise that the therapeutic efficacy of these inhibitors is due to their effects on activating the tumor suppressor protein P53, as currently accepted by the international scientific community. These results extend the potential use of USP7 inhibitors to a wider range of patients.
A person who owns a car or who has a college education may be less vulnerable to COVID-19, according to an analysis of cases in Tehran, Iran, one of the early epicenters of the pandemic. While such variables do not inherently lower a person's risk, they do indicate an infrastructure of protection that persists despite how densely populated a person's district might be.
