University of Texas at Dallas mechanical engineers have designed a 3D-printed femur that could help doctors prepare for surgeries to repair bones and develop treatments for bone tumors.
The engineers, who worked in collaboration with UT…

Teens who made history with Pythagoras’ theorem discovery publish their first academic paper with new proofs
In 2022, U.S. high school students Calcea Johnson and Ne’Kiya Jackson astonished teachers when they discovered a new way to prove Pythagoras’ theorem using trigonometry after entering a competition at their local high school. As a result, both…

Two teenagers have once again proved an ancient math rule
Two years ago, a couple of high school classmates each composed a mathematical marvel, a trigonometric proof of the Pythagorean theorem. Now, they’re unveiling 10 more.
For over 2,000 years, such proofs were considered impossible….

In double breakthrough, mathematician solves two long-standing problems
A Rutgers University-New Brunswick professor who has devoted his career to resolving the mysteries of higher mathematics has solved two separate, fundamental problems that have perplexed mathematicians for decades.
The solutions to these…

Higher-order interactions can remodel the landscape of complex systems
Networks, which include nodes and connections, can help researchers model dynamic systems like the spread of disease or how the brain processes information. Pairwise interactions between nodes can represent links between individuals — how two…

Language agents help large language models ‘think’ better and cheaper
The large language models that have increasingly taken over the tech world are not “cheap” in many ways. The most prominent LLMs, GPT-4 for instance, took some $100 million to build in the form of legal costs of accessing training data,…

Recent study reveals reduced maths performance of adults with Dyspraxia
Dyspraxia, also known as Developmental Coordination Disorder (DCD), can have a bigger impact on adult mathematical performance than previously thought, according to new research from the University of Surrey.
DCD is a prevalent neurodevelopmental…

Big algebras: A dictionary of abstract math
Several fields of mathematics have developed in total isolation, using their own ‘undecipherable’ coded languages. In a new study published in PNAS, Tamás Hausel, professor of mathematics at the Institute of Science and Technology Austria…

Mathematical proof: Five satellites needed for precise navigation
As a rule, GPS indicates our location with an accuracy of just a few meters. But we have all experienced situations where the possible error increases to a few hundred meters or the indicated location is simply wrong. One reason for this can be…

Mathematicians model a puzzling breakdown in cooperative behavior
Darwin was puzzled by cooperation in nature — it ran directly against natural selection and the notion of survival of the fittest. But over the past decades, evolutionary mathematicians have used game theory to better understand why mutual…
