Indian-Origin Student Solves Century-Old Math Problem, Boosting Wind Energy Efficiency

USUnited States|

Divya Tyagi, an Indian-origin student at Pennsylvania State University, has solved a 100-year-old mathematical problem that could revolutionize wind turbine design and enhance wind energy production. Pursuing a master's degree in aerospace engineering, Tyagi refined a mathematical model originally posed by British aerodynamicist Hermann Glauert, which focused on maximizing turbine power output but overlooked additional critical factors such as rotor forces and blade bending under wind pressure.

Her advancements, published in Wind Energy Science, include an addendum that identifies ideal flow conditions for turbines, thus maximizing their aerodynamic performance. "I created an addendum to Glauert’s problem which determines the optimal aerodynamic performance of a wind turbine," Tyagi explained.

Her adviser, Professor Sven Schmitz, highlighted the potential impact of her discoveries on future wind turbine technology, noting that her elegant solution could be integrated into educational curricula worldwide. Tyagi, also a recipient of the Anthony E. Wolk Award, emphasized the significance of even a 1% improvement in turbine power coefficient, stating it could substantially increase energy production, potentially powering an entire neighborhood.

Actor Jonathan Joss Fatally Shot in Alleged Homophobic Attack

Jonathan Joss, a 59-year-old actor known for his role as John Redcorn in the animated series “King of the Hill,” was fatally shot during a dispute with a neighbor in San Antonio, Texas, over the weekend. According to TMZ, the incident occurred on Sunday night when Joss and the suspect, Sigfredo Ceja Alvarez, engaged in a heated argument, leading Alvarez to shoot Joss multiple times. Joss was pronounced dead at the scene, and Alvarez was arrested nearby and charged with murder. Joss' husband, Tristan Kern de Gonzales, indicated that the shooting was motivated by homophobia, stating that the couple had experienced ongoing harassment from their neighbors. In a heartfelt Facebook post, de Gonzales reported prior threats to law enforcement, claiming “nothing was done” to address the situation. He described the attack as unprovoked, emphasizing that Joss had acted to protect him during the shooting. Joss is also recognized for his roles in “Parks and Recreation,” “Tulsa King,” and films like "True Grit" and "The Magnificent Seven."

US Supreme Court Upholds Trump's Move to Revoke Status of Migrants

The US Supreme Court has backed President Donald Trump's decision to revoke temporary legal status for over 532,000 migrants from Venezuela, Cuba, Haiti, and Nicaragua, significantly impacting their residency in the United States. This ruling, issued on May 30, 2025, overturned a lower court's injunction that had blocked the administration's efforts to end the immigration "parole" granted under former President Joe Biden. Immigration parole allows individuals to live and work in the US under "urgent humanitarian reasons." Trump's administration argued that rescinding this status would streamline deportation processes, facilitating what they termed "expedited removal." The decision faced dissent from Justices Ketanji Brown Jackson and Sonia Sotomayor, who criticized the court's assessment, highlighting the severe human consequences for vulnerable migrants. The ruling is part of a broader trend, as Trump has sought to implement stricter immigration policies since his return to office, including attempts to eliminate protections for migrants established by Biden. Legal representatives for the affected migrants claim the administration's actions violate existing federal laws by terminating their status without proper review.

Scientists Warn of Possible Cosmic Chaos for Earth in Billions of Years

A recent study published in the journal Icarus raises concerns about the potential impact of a passing star on Earth's orbit over the next five billion years. Researchers led by Nathan Kaib from the Planetary Science Institute indicate that there is about a five percent chance a wayward star could approach within 100 astronomical units of our solar system, significantly affecting the orbits of planets, including Earth. The study suggests that if such an event were to occur, Mercury's orbit could become highly elliptical, potentially resulting in collisions with the Sun or Venus. This scenario could further trigger catastrophic consequences, sending Venus or Mars hurtling toward Earth. However, the researchers note that the probability of these events happening is only 0.2 percent. Kaib emphasized that previous estimates had severely underestimated the likelihood of significant orbital changes within our solar system. The research hints at historical alterations in Earth's climate, previously attributed to similar celestial events. "It's a little scary how vulnerable we may be to planetary chaos," commented Renu Malhotra, a planetary scientist at the University of Arizona, highlighting the delicate balance of cosmic forces at play.
