The optimal immune repertoire for bacteria
The optimal immune repertoire for bacteria
Researchers develop a physical model that describes the optimal amount of ‘memory’ of prior infections that bacteria should have in order to efficiently mount a successful immune response.
New minor planets beyond Neptune
New minor planets beyond Neptune
This updated catalog of trans-Neptunian objects and the methods used to find them could aid in future searches for undiscovered planets in the far reaches of the solar system.
Where math meets physics
Where math meets physics
Collaborations between physicists and mathematicians at Penn showcase the importance of research that crosses the traditional boundaries that separate fields of science.
Looking to mud to study how particles become sticky
Looking to mud to study how particles become sticky
A collaboration of geophysicists and fluid mechanics experts led to a fundamental new insight into how tiny ‘bridges’ help particles of all kinds form aggregates.

Penn senior Srinivas Mandyam awarded Churchill Scholarship
Mandyam will graduate in May with a bachelor’s degree in physics, mathematics, and biophysics, along with a master’s in physics; the scholarship awards him a year of graduate research study in physics at the University of Cambridge.
Kirigami designs hold thousands of times their own weight
Kirigami designs hold thousands of times their own weight
A team of researchers found that using the origami-inspired art of paper cutting and folding, it is possible to create super strong models from lightweight soft materials without the need for adhesives or fasteners.
How biology creates networks that are cheap, robust, and efficient
How biology creates networks that are cheap, robust, and efficient
Physicists describe how vascular networks, collections of vessels that move fluid, nutrients, and waste, balance robustness with “cost” to create a diverse array of structures and designs.
New astronomical instrument on the hunt for exoplanets
New astronomical instrument on the hunt for exoplanets
A state-of-the-art instrument called NEID, from the Tohono O’odham word meaning “to see,” collected its “first light” and is poised to look for new planets outside the solar system.
A close look at thin ice
A close look at thin ice
A pairing of theory and experiment led to discovering atomic-scale details of the growth of ice on surfaces, which can inform the design of materials that make ice removal simple and cheaper.
Researchers use a material’s ‘memory’ to encode unique physical properties
Researchers use a material’s ‘memory’ to encode unique physical properties
A new study shows that, as materials age, they “remember” prior stresses and external forces, which scientists and engineers can then use to create new materials with unique properties.
