Trump Declares BRICS "Dead," Threatens 100% Tariffs on Alternative Currency

Divya Tyagi, an Indian-origin master’s student in aerospace engineering at Pennsylvania State University, has made significant advancements in wind energy production by solving a century-old mathematical problem. Her breakthrough in refining a model originally posed by British aerodynamicist Hermann Glauert could lead to improved wind turbine designs and enhanced efficiency, according to Penn State University’s official website. By addressing limitations in Glauert’s model, which focused solely on the maximum power output of wind turbines, Tyagi's solution incorporates additional critical factors such as rotor forces and blade bending under wind pressure. “I created an addendum to Glauert’s problem which determines the optimal aerodynamic performance of a wind turbine,” she stated. Her research, published in Wind Energy Science, not only simplifies complex calculations but helps maximize the power output of wind turbines. Sven Schmitz, Tyagi’s advisor, praised her work, noting its potential impact on the next generation of wind turbines. Tyagi was awarded the prestigious Anthony E. Wolk Award for her thesis, emphasizing the importance of her contributions to sustainable energy solutions.

NASA has reported that a 540-foot asteroid, designated 2014 TN17, is heading toward Earth at a speed of 77,282 km/h. This asteroid, which is roughly twice the size of the Taj Mahal, is classified as a potentially hazardous asteroid due to its size and proximity risk. Although its trajectory poses no current threat, continuous monitoring is warranted given the potential for gravitational disturbances to alter its path. The asteroid will make its closest approach on March 26, 2025, at 5:04 PM IST, coming within 5 million kilometers of Earth, more than 13 times the distance from the Earth to the Moon. According to NASA's Center for Near-Earth Object Studies, even a minor deviation in the asteroid's orbit could have catastrophic consequences, similar to the Tunguska event in 1908, when an explosion believed to be caused by an impacting object flattened about 80 million trees. Astronomers globally are closely monitoring Apollo group asteroids, including 2014 TN17, to ensure early detection and risk management.

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.
