New Hampshire Man Becomes Second Person to Live with Pig Kidney, Free from Dialysis

A groundbreaking proposal in the journal *Reports on Progress in Physics* suggests a radical rethinking of our understanding of quantum physics and gravity. Researchers, including co-author Jukka Tulkki, argue that traditional views are flawed and advocate for a model termed "unified gravity," which could reconcile quantum mechanics and general relativity, two theories known to be mathematically incompatible. The proposed theory posits that gravity is governed by four interconnected components, allowing for greater compatibility between time-space bending, as described by general relativity, and the behavior of subatomic particles, articulated by quantum field theory. Tulkki stated, "Our theory does not need extra dimensions that do not have direct experimental support," as past theories have suggested. While the framework offers potential for future experimental validation, co-author Mikko Partanen cautioned that significant advancements in both theoretical and observational physics may take decades to yield direct evidence of these proposed quantum gravity effects. Current explorations aim to provide a coherent explanation for longstanding discrepancies in physics.

A groundbreaking theoretical proposal published in the journal *Reports on Progress in Physics* challenges longstanding perceptions of quantum physics and gravity. Researchers suggest that current models, which include both quantum mechanics and general relativity, are fundamentally incompatible. The proposed theory, known as unified gravity, aims to reconcile these frameworks by positing that gravity is influenced by four interconnected components. Co-author Jukka Tulkki explained, “Our theory does not need extra dimensions that do not yet have direct experimental support,” allowing it to be tested within known physics. The significant difference from existing theories, such as string theory, which has faced criticism for its lack of empirical validation, marks a new direction in the quest to merge quantum and gravitational theories. Study co-author Mikko Partanen noted that while direct evidence of quantum gravity effects may take decades to achieve, advances in observational technologies could yield indirect evidence sooner. This proposal sets the stage for a potential paradigm shift in our understanding of the universe's mechanics.

Former U.S. President Joe Biden, aged 82, has been diagnosed with an aggressive form of prostate cancer that has metastasized to his bones, his office announced on May 18, 2025. Following the discovery of urinary symptoms and a prostate nodule, Biden and his family are exploring treatment options, according to his office, which noted that the cancer appears to be hormone-sensitive and can be managed effectively. Biden's Gleason score, a measure of cancer aggressiveness, was reported to be nine, indicating a severe form of the disease. Prostate cancer is recognized as the most common cancer among men in the U.S. Biden has a history of skin cancer removal and made addressing cancer a priority during his presidency, launching a "cancer moonshot" initiative aimed at reducing cancer death rates. Political figures, including former President Donald Trump and former Vice President Kamala Harris, expressed concern and support for Biden following his diagnosis. Harris emphasized that Biden has the resilience to face this challenge. The diagnosis has intensified discussions regarding Biden's health, particularly amid ongoing scrutiny of his age and cognitive abilities.
