Secret of efficient photosynthesis: Purple bacteria's light-harvesting prowess lies in highly symmetrical molecules
Purple bacteria are among Earth's oldest organisms, and among its most efficient in turning sunlight into usable chemical energy. Now, a key to their light-harvesting prowess has been explained through a detailed structural ...
Simulations show early farming might have caught on due to development of property rights
Earth's center is out of sync
(Phys.org) —We all know that the Earth rotates beneath our feet, but new research from ANU has revealed that the center of the Earth is out of sync with the rest of the planet, frequently speeding up and ...
Glass has potential to be stronger, researchers say
(Phys.org)—Glass is strong enough for so much: windshields, buildings and many other things that need to handle high stress without breaking. But scientists who look at the structure of glass strictly by ...

Jellyfish replacing fish in over-exploited areas
Princeton researchers solve problem filling space -- without cubes
(PhysOrg.com) -- Whether packing oranges into a crate, fitting molecules into a human cell or getting data onto a compact disc, wasted space is usually not a good thing.
How the lily blooms: A mathematical perspective (w/ video)
The "lily white" has inspired centuries' worth of rich poetry and art, but when it comes to the science of how and why those delicately curved petals burst from the bud, surprisingly little is known.
Rock-paper-scissors tournaments explain ecological diversity
According to classical ecology, when two species compete for the same resource, eventually the more successful species will win out while the other will go extinct. But that rule cannot explain systems such as the Amazon, ...
