New Theory Proposes Major Changes to Understanding of Gravity

USUnited States|

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.

Joe Biden Diagnosed with Aggressive Prostate Cancer

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.

Deadly Tornadoes Strike Midwest US, Leaving 27 Dead

A series of tornadoes swept through the Midwest and Ohio River Valley late Friday, resulting in at least 27 fatalities and numerous injuries across Missouri, Kentucky, and Virginia, officials reported. Kentucky sustained the most damage, with 18 people confirmed dead and another 10 hospitalized in critical condition. The storms wreaked havoc in various communities, notably in London, Kentucky, where drone footage portrayed extensive destruction and uprooted homes. Kentucky's State Emergency Management Director, Eric Gibson, noted significant daylight damage to hundreds of homes and warned that the death toll could rise. Governor Andy Beshear stated that parts of two dozen state roads were closed and could remain inaccessible for days. Residents like Kayla Patterson recounted harrowing experiences, describing the tornado's immense power as it tore through neighborhoods. This event follows another severe weather incident in March, which claimed 24 lives in the region. Experts express concern over the potential implications of reduced staffing in National Weather Service offices following administrative cuts on timely disaster warnings.

Brain-Dead Woman in Georgia Kept on Life Support Amid Abortion Law Controversy

Adriana Smith, a 30-year-old pregnant woman from Georgia, USA, has been on life support for over three months after being declared brain-dead. The family claims her continued life support is due to Georgia’s restrictive abortion laws that prevent them from ending life support despite her condition. Currently 21 weeks pregnant, Smith's situation may become one of the longest documented cases of a brain-dead woman carried in such a state. According to reports, Smith, a registered nurse, experienced severe headaches in February and was later diagnosed with blood clots in her brain, leading to her declaration of brain death. Family members, including her young son, have maintained a vigil by her side, unaware of her true condition. Georgia's "heartbeat law," enacted after the Supreme Court's 2022 ruling on abortion rights, bans abortions once cardiac activity in the fetus is detected, typically around six weeks of pregnancy. Legal exceptions for maternal health have been criticized for their narrow interpretations, complicating decisions in cases like Smith's, according to the Associated Press.
