Researchers are making significant strides in reducing the costs associated with quantum randomness, a crucial element for cryptography and simulations. Traditionally, obtaining true quantum randomness has been complex and expensive. However, the exploration of "pseudorandomness" offers a practical alternative, allowing researchers to utilize computational algorithms that mimic randomness, thus sidestepping the high costs of pure quantum randomness. This development broadens the accessibility of randomness, enabling researchers to pursue new scientific investigations.
The team from JPMorganChase, Quantinuum, multiple national labs, and UT Austin demonstrated a certified quantum randomness protocol. They showcased the first successful demonstration of a quantum computing method to generate certified randomness. Using a 56-qubit quantum machine, they output more randomness than they initially put in. What makes this truly remarkable is that this feat is considered impossible for even the most powerful classical supercomputers. This groundbreaking achievement could open new doors for quantum computing and cryptography research. Recommended read:

Terence Tao has recently uploaded a paper to the arXiv titled "Decomposing a factorial into large factors." The paper explores a mathematical quantity, denoted as t(N), which represents the largest value such that N! can be factorized into t(N) factors, with each factor being at least N. This concept, initially introduced by Erdös, delves into how equitably a factorial can be split into its constituent factors.
Erdös initially conjectured that an upper bound on t(N) was asymptotically sharp, implying that factorials could be split into factors of nearly uniform size for large N. However, a purported proof by Erdös, Selfridge, and Straus was lost, leading to the assertion becoming a conjecture. The paper establishes bounds on t(N), recovering a previously lost result. Further conjectures were made by Guy and Selfridge, exploring whether relationships held true for all values of N. On March 30th, mathematical enthusiasts celebrated facts related to the number 89. Eighty-nine is a Fibonacci prime, and patterns emerge when finding it's reciprocal. Also, the number 89 can be obtained by a summation of the first 5 integers to the power of the first 5 Fibonacci numbers. 89 is also related to Armstrong numbers, which are numbers that are the sum of their digits raised to the number of digits in the number.

Recent mathematical research is pushing the boundaries of theoretical understanding across various domains. One area of focus involves solving the least squares problem, particularly with rank constraints. A specific problem involves minimizing a function with a rank constraint and the quest for efficient solutions to these constrained optimization challenges remains a significant area of investigation.
This also involves a three-level exploration into a "mathematics-driven universe," questioning whether math is discovered or invented, and delving into the philosophical implications of mathematics in modern physics. Furthermore, mathematicians are employing topology to investigate the shape of the universe. This includes exploring possible 2D and 3D spaces to better understand the cosmos we inhabit, hinting at intriguing and surprising possibilities that could change our understanding of reality.

The American Mathematical Society (AMS) is actively advocating for mathematics, particularly concerning the National Science Foundation (NSF). The AMS has started a page to coordinate support for professional mathematics, focusing on executive orders impacting the NSF. Recently, the NSF has seen significant changes, including the firing of 168 employees, which raises concerns about the potential impact on quantum funding and artificial intelligence research. These layoffs, occurring in response to a presidential executive order aimed at reducing the federal workforce, have affected both probationary employees and part-time experts in physics-related fields.
The AMS provides tools for the mathematical community to engage with government representatives, ensuring that the voices of mathematicians are heard in policy discussions. The AMS also actively supports mathematics on a global stage, as demonstrated by the US team earning third place at the 2025 Romanian Master of Mathematics, a challenging international high school mathematics competition, with team members earning individual awards. Penn State also rose in the NSF Higher Education Research and Development rankings. The AMS is dedicated to advancing research and connecting the diverse global mathematical community through publications, meetings and conferences, MathSciNet, professional services, advocacy, and awareness programs.

NASA's James Webb Space Telescope (JWST) has peered into the early Universe, observing galaxies from just a few hundred million years after the Big Bang. With its unique infrared sensitivity, JWST allows researchers to examine these ancient galaxies and uncover secrets from the Universe's formative years. The telescope's NIRCam (Near-Infrared Camera) played a key role in these observations.
An international team of astronomers has identified bright hydrogen emission from a galaxy, JADES-GS-z13-1, at an unexpectedly early time. This distant galaxy, observed just 330 million years after the Big Bang, has a redshift (z) of 13, indicating its age and distance. This discovery challenges existing understanding of how light could have pierced the thick fog of neutral hydrogen that filled space at that time. Recommended read:
