Claimed room-temperature superconductor LK-99, discovered by a South Korean team, sparks viral buzz but faces skepticism. The material, a copper-lead-phosphorus-oxygen compound, exhibits supposed superconductivity at up to 127°C. Initial replication attempts by Indian and Chinese teams fail to observe superconductivity, although one notes low resistance at -163°C. Theoretical analyses hint at interesting electronic features, but consensus on crystal structure is lacking. Unverified videos of levitating samples circulate online. Scientists caution against overhyping, recalling past unsubstantiated claims. While attention is high, doubts persist amid scientific and online communities, leading to humorous responses mocking levitation videos.
We live in a digital era where social media has revolutionized the way the world connects. It has empowered us to exchange our thoughts with a wider audience in a cost-effective manner. In simple terms, social media can be explained as interactive internet applications that enable users to engage in the development and dissemination of […]
The study in Barcelona investigated the influence of personal concentrations of per- and polyfluoroalkyl substances (PFAS), persistent organic pollutants (POPs), and chemical elements in individuals’ blood (collected in 2016-2017) on SARS-CoV-2 infection and COVID-19 outcomes. PFAS were not associated with SARS-CoV-2 seropositivity or COVID-19. However, previously identified mixtures of POPs and elements were significantly associated […]
Scientists have created a compact and efficient gene-editing tool, called engineered AsCas12f, smaller than the common Cas9 enzyme. It was tested successfully in mice, demonstrating promise for treating genetic disorders like hemophilia. The key advantage is that it can be packed more efficiently into delivery systems, potentially advancing gene therapy for humans. However, further research […]
