Bones from shipwreck suggest right- or left-handedness could affect how clavicle chemistry changes with age
A new study of human skeletal remains from the wreck of the 16th century English warship "Mary Rose" suggests that whether a person is right- versus left-handed may influence how their clavicle bone chemistry changes as they age. Dr. Sheona Shankland.....»»
Solar-powered animal cells: Combining chloroplasts from algae with hamster cells
Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in.....»»
AI training method can drastically shorten time for calculations in quantum mechanics

Why Are Close Elections So Common?
When voters decide between two alternatives, as is effectively the case in the U.S. presidential election, it usually comes down to a neck-and-neck race. Researchers can now explain this mathematically.....»»
How life began on Earth: Model suggests ancient Earth had organic-rich atmosphere
The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model that considers various atmospheric chemical reactions to estimat.....»»
Stochastic thermodynamics may be key to understanding energy costs of computation
Two systems exist in thermal equilibrium if no heat passes between them. Computers, which consume energy and give off heat as they process information, operate far from thermal equilibrium. Were they to stop consuming energy—say you let your laptop.....»»

Researchers find Weddell seals avoid extreme dives at midday
Erebus Bay, Antarctica, is home to the southernmost population of the world's southernmost living mammal—the Weddell seal. These seals may look like couch potatoes when they are resting on the ice, but Weddell seals go to great lengths to make a li.....»»
Scientists create a molecular switch that can control cell division on demand outside of a living system
A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction. Cell division is a grand event which completely transforms the landscape. The cell starts behaving like the host of an interna.....»»
