Andrew Krapivin, an undergraduate at Rutgers University, has made a groundbreaking contribution to computer science by developing a new type of hash table that can locate data faster than previously believed, effectively discrediting a conjecture established 40 years ago. Alongside his collaborators, Martín Farach-Colton and William Kuszmaul, Krapivin's work was published in a January 2025 paper and challenges established theories surrounding the efficiency of hash tables, a widely utilized data structure. Historically, hash tables have facilitated efficient data storage and retrieval, with origins tracing back to the early 1950s. In a pivotal 1985 paper, renowned computer scientist Andrew Yao claimed that the worst-case query time for certain hash tables could never be better than linearly proportional to the table's fullness. Krapivin, unaware of this conjecture, instead devised a mechanism that reduces the search time dramatically, achieving a constant average time regardless of the hash table's fullness. Experts, including Alex Conway from Cornell Tech, have hailed the findings as significant, noting their potential to reshape understanding in this area of computer science.

In a significant development, U.S. President Donald Trump and Russian President Vladimir Putin engaged in a two-hour phone call, resulting in a temporary ceasefire regarding attacks on energy infrastructure in Ukraine. According to a statement from the Kremlin, the two leaders had a "detailed and frank exchange of views" and agreed to a halt in strikes for a period of 30 days. Putin, during the conversation, urged the cessation of forced mobilization and the rearmament of Ukrainian forces, emphasizing that these measures are critical for a sustainable peace process. This dialogue comes amid growing international concerns about the ongoing conflict and its broader implications. While both parties have expressed a commitment to de-escalation, experts remain cautious, noting the complex nature of negotiations in such a volatile situation. The ceasefire is seen as a positive step, but its long-term effectiveness remains to be evaluated. The agreement marks a notable milestone in U.S.-Russia relations, with both leaders acknowledging the necessity to stabilize the situation in Ukraine.

Brittany Fortinberry, a 31-year-old former teacher at Eminence High School in Martinsville, Indiana, is facing escalating charges after multiple teenage boys came forward with allegations of sexual abuse. Initially charged with sexually assaulting a 15-year-old and communicating explicit content to other students, Fortinberry is now accused by at least ten boys of engaging in inappropriate sexual conduct, including "group sex" (WXIN). Reports indicate that some victims, as young as 13, are claiming Fortinberry provided them with drugs and paid for explicit photographs, with sums reportedly reaching $800. One victim recounted being pressured into various sexual activities, including being forced to wear a Ghostface mask. He also stated that Fortinberry manipulated them into consuming mushrooms and alcohol, making their recollections of events difficult (WRTV). Following the initial allegations in August 2024, Fortinberry was suspended from her teaching position. In a statement following her arrest, she expressed regretting having lost weight, suggesting that it might have influenced her actions in the past. The investigation into the case is ongoing as authorities seek to gather more evidence (Dailymail).
