New 'pomegranate-inspired' design solves problems for lithium-ion batteries Posted: 16 Feb 2014 12:17 PM PST A novel battery electrode features silicon nanoparticles clustered like pomegranate seeds in a tough carbon rind. The design could enable smaller, lighter rechargeable batteries for electric cars, cell phones and other devices.

Researchers rejuvenate stem cell population from elderly mice, enabling muscle recovery Posted: 16 Feb 2014 12:17 PM PST Researchers have pinpointed why normal aging is accompanied by a diminished ability to regain strength and mobility after muscle injury: over time, stem cells within muscle tissues dedicated to repairing damage become less able to generate new muscle fibers and struggle to self-renew. Scientists identified for the first time a process by which the older muscle stem cell populations can be rejuvenated to function like younger cells.

Volcanoes, including Mt. Hood, can go from dormant to active in a few months Posted: 16 Feb 2014 12:17 PM PST A new study suggests that the magma sitting 4-5 kilometers beneath the surface of Oregon's Mount Hood has been stored in near-solid conditions for thousands of years, but that the time it takes to liquefy and potentially erupt is surprisingly short -- perhaps as little as a couple of months.

Growing number of chemicals linked with brain disorders in children Posted: 14 Feb 2014 05:39 PM PST Toxic chemicals may be triggering the recent increases in neurodevelopmental disabilities among children -- such as autism, attention-deficit hyperactivity disorder, and dyslexia.

Another reason to not mix work, family: Money makes parenting less meaningful, study suggests Posted: 14 Feb 2014 10:09 AM PST Money and parenting don't mix. That's according to new research that suggests that merely thinking about money diminishes the meaning people derive from parenting. The study is one among a growing number that identifies when, why, and how parenthood is associated with happiness or misery.

Embryology: Scientists crack open 'black box' of development and see a 'rosette' Posted: 13 Feb 2014 11:23 AM PST We know much about how embryos develop, but one key stage -- implantation -- has remained a mystery. Now, scientists have discovered a way to study and film this 'black box' of development. This new method revealed that on its way from ball to cup, the blastocyst becomes a 'rosette' of wedge-shaped cells, a structure never before seen by scientists.

America's natural gas system is leaking methane and in need of a fix Posted: 13 Feb 2014 11:22 AM PST The US natural gas system is letting more methane, a potent greenhouse gas, escape into the air than previously thought, a new study confirms.

Apollo reflectors performance: Source of 'full moon curse' revealed by eclipse Posted: 11 Feb 2014 09:18 AM PST Signals bounced off reflectors on the lunar surface return surprisingly faint echoes on full moon nights. Scientists think it's the result of uneven heating of the reflective lenses, which would alter their refractive index, dispersing the return beam, and they found compelling evidence for this explanation during an eclipse as Earth's shadow passed over each reflector in turn.

How Were The Egyptian Pyramids Built? Posted: 28 Mar 2008 07:43 AM PDT The Aztecs, Mayans and ancient Egyptians were three very different civilizations with one very large similarity: pyramids. However, of these three ancient cultures, the Egyptians set the standard for what most people recognize as classic pyramid design: massive monuments with a square base and four smooth-sided triangular sides, rising to a point. The Aztecs and Mayans built their pyramids with tiered steps and a flat top.
