Calcium absorption not the cause of evolution of milk digestion in Europeans
Ancient DNA from early Iberian farmers shows that the wideheld evolutionary hypothesis of calcium absorption was not the only reason Europeans evolved milk tolerance.
Researchers devise means to combine scanning tunneling microscopy and infrared spectroscopy
Regulating electron 'spin' may be key to making organic solar cells competitive
Organic solar cells that convert light to electricity using carbon-based molecules have shown promise as a versatile energy source but have not been able to match the efficiency of their silicon-based counterparts.
White dwarf star throws light on possible variability of a constant of Nature
An international team led by the University of New South Wales has studied a distant star where gravity is more than 30,000 times greater than on Earth to test its controversial theory that one of the constants ...
Team provides new insight into photosynthesis
Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they ...
Cutting light with a comb
(Phys.org)—Quantum physicists from ETH Zurich have discovered special properties in a laser, thanks to which portable devices can be built to analyse gases and liquids accurately and reliably in the future.
The self-improvement of lithium-ion batteries
(Phys.org)—The search for clean and green energy in the 21st century requires a better and more efficient battery technology. The key to attaining that goal may lie in designing and building batteries not ...
