Harvard University is implementing a new grading policy to combat grade inflation, limiting A grades to 20% of students starting in 2027. This move aims to restore the meaning of top grades and reduce pressure on students to maintain perfect transcripts. The decision comes amid broader scrutiny of academic standards in higher education.

Chinese President Xi Jinping invoked the "Thucydides Trap" during talks with US President Donald Trump, highlighting concerns that the rising power's growth could lead to conflict with the established dominant power. This theory, popularized by Graham Allison, suggests structural tensions make war more likely, a concept now central to global geopolitical debates involving trade wars and technological competition.

Once a celebrated Harvard nanoscience professor, Charles Lieber, convicted in the US for false statements tied to Chinese payments, now leads state-backed brain-computer interface research in Shenzhen. His move to i-BRAIN, a key institute, highlights China's focus on this medically promising yet strategically sensitive field, drawing global attention to his new role.

And that’s the trap that ‘Philosopher King’ Xi Jinping wants to avoid when coming up against Don Tzu, but who is Thucydides anyway? What trap did he lay? And will the US and China go to war?

MIT scientists have engineered a revolutionary brain imaging tool, converting chaotic laser light into a focused beam. This breakthrough allows for 3D imaging of the blood-brain barrier at 25 times the speed of current methods. The technology offers real-time drug delivery tracking, promising significant advancements in neurological disease research and drug development.

Parrots possess a remarkable ability to mimic human speech due to their unique vocal organs and brain structure, enabling them to learn and replicate sounds with exceptional accuracy. While they use imitation for social bonding and interaction, this mimicry is primarily associative learning, not true linguistic comprehension.

A new study offers hope for Indian farmers facing climate change. Scientists have discovered how plants regulate water loss. This breakthrough could lead to crops that better withstand drought. The research, involving a scientist from Bengal, may help improve food security in drought-prone regions. Efforts are underway to apply these findings to maize cultivation.

Astrophysicist Priyamvada Natarajan discusses the challenges facing international students in the US due to shrinking research funding and the transformative impact of AI on scientific methods. She highlights her journey from India, emphasizing the importance of curiosity and lifelong learning, and her contributions to understanding dark matter and black holes.

As America eyes the moon again, UFO interest surges, fueled by Obama's 'real' alien comment and Trump's promise of file releases. Scientists ponder alien judgment of human conflict, while pop culture reflects our own fears. The Pentagon acknowledges UAPs but finds no extraterrestrial link, yet some claim 'nonhuman intelligence' is real, urging transparency.

Avi Loeb has urged NASA to redirect the Curiosity Rover to examine a mysterious 20-centimetre cylindrical object spotted in Gale Crater. While likely debris from the rover’s landing system, its origin remains unconfirmed. Loeb argues that investigating it should take priority over routine exploration, though NASA has not yet responded publicly.
