Reverse engineering Jackson Pollock

October 27, 2023

Professor L. Mahadevan, Lola England de Valpine Professor of Applied Mathematics at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), and Professor of Organismic and Evolutionary Biology, and of Physics in the Faculty of Arts and Sciences (FAS), led a team of researchers that trained a machine to paint like Jackson Pollock.

The team asked if 3D-printing could apply Pollock's distinctive techniques to quicky and accurately print complex shapes. The team combined physics and machine learning to develop a new 3D-printing technique that...

480-Million-year-old fossil reveals ancient seafloor communities

October 11, 2023

In a study published in Nature, researchers, led by postdoctoral researcher Karma Nanglu, describe a 480-million-year-old cephalod from Morocco that shows the earliest example of ocean bottom dwellers making their home in dead bodies.

Dead bodies in the ocean drift to the bottom where they become home to bottom dwellers, the practice dates back to 530 million years ago. During the Paleozoic era, however, it became much harder to track the interspecies interactions. Nanglu and co-authors,...

Saving the frogs from existential threats

October 4, 2023

Amphibians, the first vertebrates to inhabit land 360 million years ago, are facing existential threats due to climate change, habitat destruction, and disease.

Postdoctoral researcher Sonali Garg and associate Sathyabhama Das Biju co-authored a new study published in Nature that assesses the global status of amphibians. Garg and Biju are experts in frog biology and have documented more than 100 new frog species across India, Sri Lanka, and other parts of the subcontinent. Garg,...

Interdisciplinary summer program makes sharks accessible for students

August 18, 2023

Professor George Lauder teamed with scientists from Yale University and the University of Florida to host three students for an eight week summer program called Accessible Sharks. The program is part of the NSF funded Research Experience for Undergraduates (REU) and was designed specifically for students with disabilities.

Lauder hosted Dakota Law, a rising senior in engineering sciences at Smith College. Law, who has an invisible disability, had never worked in a lab or held a shark. But, by the end of the eight-week program she was proudly displaying a chain catshark to...
