Shape-shifting materials with infinite possibilities

October 21, 2021

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) led by L Mahadevan, the Lola England de Valpine Professor of Applied Mathematics, of Organismic and Evolutionary Biology, and of Physics, have developed a shape-shifting material that can take and hold any possible shape. The study published in the Proceedings of the National Academy of Sciences paves the way for a new type of multifunctional material that can be used in a range of applications, from...

International team of researchers discover first dinosaur era crab fully preserved in amber

October 20, 2021

Fossils trapped in amber provide a unique snapshot of the anatomy, biology, and ecology of extinct organisms. The most common fossils found in amber, which is formed from resin exuded from tree bark, are land-dwelling animals, mainly insects. But on very rare occasions scientists discover amber housing an aquatic organism.

In a study published October 20 in Science Advances an international team of researchers describe the first crab from the Cretaceous dinosaur era preserved in amber. The study...

Researchers describe new tardigrade fossil found in 16 million year old Domincan amber

October 6, 2021

Tardigrades, also known as water bears, are a diverse group of charismatic microscopic invertebrates that are best known for their ability to survive extreme conditions. A famous example was a 2007 trip to space where tardigrades were exposed to the space vacuum and harmful ionizing solar radiation, and still managed to survive and reproduce after returning to Earth. Tardigrades are found in all the continents of the world and in different environments including marine, freshwater, and terrestrial.

Tardigrades have survived all five Phanerozoic Great Mass Extinction events,...

How apples get their shapes

October 5, 2021

L Mahadevan, the Lola England de Valpine Professor of Applied Mathematics, of Organismic and Evolutionary Biology, and of Physics at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and a team of mathematicians and physicists have used observations, lab experiments, theory and computation to understand the growth and form of the cusp of an apple. 

The team collected apples at various growth stages from an orchard at Peterhouse College at University of Cambridge in the U.K. They then mapped the growth of the dimple, or cusp...

Cassandra Extavour Selected as HHMI Investigator

September 23, 2021

Congratulations to Cassandra Extavour selected as one of 33 Howard Hughes Medical Institute (HHMI) Investigators. Extavour is investigating the ancient origins of germ cells, which are the only cells in the body to pass on their genes, making germ cells central to the process of evolution. Extavour studies the evolutionary processes that led to the formation of the first egg cell. “While my research...

Bowfin genome reveals old dogfish can teach researchers new tricks

August 30, 2021

The fish species Amia calva goes by many names including bowfin, freshwater dogfish, grinnel, and mud pike. No matter what you call it, this species is an evolutionary enigma because it embodies a unique combination of ancestral and advanced fish features.

In a paper published August 30 in Nature Genetics an international and collaborative team of researchers, headed by Ingo Braasch and Andrew Thompson of...
