Engineers have long designed tough materials from tidy grids, because order is easy to predict. Nature often does the opposite: bone and spider silk owe part of their resilience to irregular, messy structure. A team led by The Chinese University of Hong Kong has now used physics-guided AI to design lightweight materials that borrow that lesson, and the printed results were tougher than the team had targeted.
According to CUHK's press release, the study appeared in Physical Review X and was ...

Link between comet, asteroid showers & mass extinctions.
Dr Ken Caldeira of Carnegie Institution and Dr Michael Rampino of New York University offer new support linking the age of these craters with recurring mass extinctions of life, including the demise of the dinosaurs. Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers.
Specifically, they show a cyclical pattern over the studied period, with both impacts and extinction events taking place every 26 million years. This cycle has been linked...

Telomere Changes Predict Cancer
A simple blood test may be able to predict cancer years before a diagnosis.
A distinct pattern in the changing length of blood telomeres, the protective end caps on our DNA strands, can predict cancer many years before actual diagnosis, according to a new study from Northwestern Medicine in collaboration with Harvard University.
"Understanding this pattern of telomere growth may mean it can be a predictive biomarker for cancer," Dr. Lifang Hou, the lead study author and a professor of prev...
