Terra Quantum-led researchers have observed room-temperature superconductivity in graphite for the first time, using scotch tape to cleave pyrolytic graphite into thin sheets. This discovery could lead to transformative advancements in superconducting technology, with potential applications in power grids, healthcare, transportation, electronics, and quantum computing. The mechanism leading to superconductivity involves the formation of structures that allow superconducting currents to flow along the wrinkles in the graphite, mediated by effective topological gauge fields and Bose condensation.
A study claiming the creation of a room-temperature superconducting material has been retracted by scientific journal Nature after Chinese researchers raised doubts about its validity. The paper, published earlier this year, gained widespread attention but was found to have manipulated data. The retraction raises questions about the initial claims and the scientific rigor behind them. Room-temperature superconductors are highly sought after for their potential applications in various fields.
Scientists have discovered a "demon" particle, known as Pines' demon, inside a superconductor called strontium ruthenate. This chargeless particle, a plasmon, could help unravel the mystery of how superconductors work. Theorists believe that plasmons may play a role in facilitating superconductivity, and understanding this could lead to the development of room-temperature superconductors, which would revolutionize electricity transmission. The discovery of Pines' demon provides a potential avenue for exploring and improving superconductors, and further research in other metals may yield valuable insights.

The discovery of Pines' demon, nearly 70 years after it was first predicted, opens up new possibilities for studying and harnessing the potential of superconductors.
The journal Physical Review Letters (PRL) is set to retract a paper by physicist Ranga Dias, who has made controversial claims about discovering room-temperature superconductors, following an investigation that found apparent data fabrication. This comes after allegations of plagiarism and a previous retraction of one of Dias's papers by Nature. The investigation found that the raw data provided by co-author Ashkan Salamat did not match the figures in the paper, leading to the conclusion of data fabrication and an attempt to obstruct the investigation. Dias denies any misconduct and remains committed to room-temperature superconductivity research, but many physicists are skeptical of his claims.
A new study has discovered a third type of superconductivity that was previously only thought to apply to extremely thin layers of materials. Researchers developed the mathematical equations that describe this new type of superconductivity in thick, three-dimensional materials, and observed their behavior in the laboratory. This new mechanism could open a door towards developing room-temperature superconductivity, a "holy grail" in the field.
