Small Asteroids May Be Clusters

Using data from the Spitzer Space Telescope, researchers have found small asteroids that are up to 65% empty space and that many smaller bodies may be clusters of rubble or a dust cloud with a solid nucleus instead of solid rocky bodies.

Water Reservoir Inside Earth

A massive reservoir of water three times the volume of Earth's oceans has been discovered 700 km down inside the mantle locked within a blue rock called ringwoodite, with the liquid "sweating" out of the mineral due to the great pressures and temperatures.

Dark Side of the Moon Mystery

Astrophysicists have solved the Lunar Farside Highlands Problem, the question dating from 1959 as to why the far side of the Moon has no maria like the near side, the explanation being that the Moon was tidally locked with Earth's orbit soon after its formation resulting in a temperature gradient and thicker crust on the side facing away from Earth.

Bacteria in Healthy Placentas

Long thought to be sterile, a new study has found that the placenta is home to a non-pathogenic bacterial community that is similar to that found in the mother's mouth and that may be linked to poorly understood pregnancy disorders.

Conflicting Neutron Decay Results

Physicists have found conflicting results for the natural decay of the neutron that depend upon the type of experiment used, with discrete lifetimes of 887.7 seconds and 878.5 seconds from two different methods lying outside experimental error and that may point to new physics not yet understood.

Metal-Eating Plant Found

Scientists have found a new species of plant (Rinorea niccolifera) in the Philippines that sustains itself by consuming nickel with its leaves accumulating 18,000 ppm without being poisoned, a level that is up to a thousand times greater than other plants.

Effect of Weak Broadband EM

Biologists studying migratory birds accidentally discovered that the effects of low-level broadband electromagnetic fields common in cities and a thousand times below the range that affects human health can disrupt the behavior and magnetic migratory sense of urban songbirds.

Two Rings around Asteroid

Astronomers have found two sharply defined rings surrounding the asteroid Chariklo, at 250 km in diameter the largest centaur orbiting between Saturn and Uranus in the outer solar system and the smallest object yet seen to host a stable ring system.

Most Distant in Solar System

Astronomers have discovered a new distant dwarf planet (2012 VP113) that is the most distant known object in our solar system, part of the inner Oort cloud with an elliptical orbit of 80 AU at its closest point to the Sun and perturbed enough to suggest the existence of a further large, planet-sized massive body.

Rare Chimeric Albino Redwood

Scientists and historians are fighting transit authorities to prevent the removal of an extremely rare 52-foot, healthy chimeric albino redwood growing near a railroad in Cotati, California, one of only ten specimens ever found that produce male and female cones as well as displaying normal and albino tissues in the same tree.

"Zebra Stripes" in Van Allen Belt

NASA's Van Allen probes have detected a persistent pattern in the inner radiation belt surrounding Earth similar to "zebra stripes," a distortion caused by the rotation of the planet that was previously thought incapable of affecting the high-energy electrons of the belts with velocities near the speed of light.

1500-Year-Old Moss Lives

Researchers have demonstrated moss frozen in ice on the Antarctic Peninsula for at least 1530 years can be revived and continue to grow, showing that a vital element of ecosystems can survive long-term, millennial-scale ice ages.

First Direct Evidence of Big Bang

Researchers studying the polarization of the cosmic microwave background have mapped the unique B-mode pattern that is consistent with that predicted for the primordial gravitational waves generated by the cosmic inflation in the fraction of a second following the Big Bang, providing the first physical evidence of gravitational waves as well as the theory of cosmic origins.

Microbe "Eats" Electricity

Researchers have found a common bacteria (Rhodopseudomonas palustris) uses a method called extracellular electron transfer (EET) to pull electrons from iron and conductive minerals found in soil for use with sunlight as nourishment in their own metabolism.
