Quantum Leap: New Topological Electronic Crystals Discovered in Graphene

CACanada|

Researchers at the University of British Columbia have discovered novel topological electronic crystals in twisted layers of graphene, an advancement published in the journal Nature. The study reveals that electrons can establish a highly ordered arrangement, akin to synchronized dancers, while remaining in place, thereby allowing electric current to move smoothly along the material's edges, effectively rendering the center non-conductive.

Joshua Folk, a physics professor and co-author of the study, explained that stacking two layers of graphene with a slight twist created a moiré pattern, transforming electron behavior. This resulted in a unique construct, termed a topological electronic crystal, where stability is maintained irrespective of minor structural imperfections.

The implications of this discovery are significant for future technologies, suggesting potential applications in energy-efficient devices and resilient quantum computing systems. Such topological materials are rare and crucial for robust quantum behavior, offering promising pathways for advancements in electronic technologies.

Hunter Fatally Mauled by Bear During Arctic Expedition in Canada

A tragic incident occurred in Nunavut, Canada, where Darryl Conack was fatally mauled by a bear during a hunting trip. The attack happened while Conack and his companions were taking a tea break after hunting narwhal and caribou, according to local reports. Eyewitness Leo Lejangiak recounted the horrifying moment, noting that a protective female bear, likely fearing for her cubs, attacked unexpectedly. Lejangiak attempted to scare the bear away by firing into the air, but it bit Laurent Junior Utack before turning its attention to Conack. Although Lejangiak secured another gun and ultimately killed both the bear and its cub, Conack had already succumbed to his injuries. Afterward, the surviving hunters wrapped Conack’s body and tried to return to their boat, now immobilized by heavy snowfall and surrounded by additional bears. A rescue team later arrived, but not without having to shoot four more bears. The incident, which marks the second fatal bear attack in Nunavut in seven years, has ignited discussions on wildlife safety in Arctic regions.

Indian Student Found Dead in Ottawa After Mysterious Disappearance

An Indian student, 21-year-old Vanshika Saini, was found dead in Ottawa, Canada, after being reported missing since April 25. According to The Times of India, Saini, the daughter of Aam Aadmi Party leader Davinder Saini, left her residence at approximately 9 PM that evening to search for a rental room and did not return. Her family reported her uncharacteristic silence, as she typically maintained regular communication with loved ones. Saini’s phone was switched off, and she subsequently missed an exam, prompting her friends to raise concern and notify local authorities. Following their search efforts, her body was discovered near a beach area in Ottawa. The Indian High Commission in Canada confirmed that they are in touch with Saini's family and stated that the local police are actively investigating the circumstances surrounding her death. As the investigation progresses, community members and friends are expressing shock and mourning the sudden loss of a student who had moved to Canada after completing her education in India.
