Lead in teeth can tell a body's tale, study finds
Your teeth can tell stories about you, and not just that you always forget to floss. The discovery could help police solve cold cases, an investigator has said. For instance, if an unidentified decomposed body is found, testing the lead in the teeth could immediately help focus the investigation on a certain geographic area. That way, law enforcement can avoid wasting resources checking for missing persons in the wrong places.

Hubble shows farthest lensing galaxy yields clues to early universe
Astronomers have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen in a new image as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record holder by 200 million years.

Pervasive implicit hierarchies for race, religion, age revealed by study
As much as social equality is advocated in the United States, a new study suggests that besides evaluating their own race and religion most favorably, people share implicit hierarchies for racial, religious, and age groups that may be different from their conscious, explicit attitudes and values.

Effect of loud noises on brain revealed in study
Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists. Exposure to intensely loud sounds leads to permanent damage of the hair cells, which act as sound receivers in the ear. Once damaged, the hair cells do not grow back, leading to noise-induced hearing loss.

Monoamine oxidase A: Biomarker for postpartum depression
Postpartum mood swings are correlated with high monoamine oxidase A binding, a study shows. For most women, the birth of their baby is one of the most strenuous but also happiest days in their lives. The vast majority of women experience a temporary drop in mood for a few days after birth. These symptoms of "baby blues" are not an illness; however, in some cases they can represent early signs of an imminent episode of depression: in 13 percent of mothers, the emotional turmoil experienced after childbirth leads to the development of a full-blown postpartum depression.

Fossils could be discovered on the moon: Signs of ancient life may be littered across the moon
Physicists have tested what would happen if a piece of rock containing microscopic fossils from Earth was launched into space and hit the surface of the moon. The team turned fossil-filled rock into powder which was mixed with water and frozen to replicate a meteoroid.

Brother of Hibiscus flower is found alive and well on Maui, Hawaii
Most people are familiar with Hibiscus flowers -- they are an iconic symbol of tropical resorts worldwide where they are commonly planted in the landscape. Only a few, however, are aware of an equally beautiful and highly endangered related group of plants known as Hibiscadelphus -- literally 'brother of Hibiscus.' Remarkably, in 2012 scientists found a population of these unique trees in a remote, steep valley on the west side of Maui.

Breakthrough in understanding of important blood protein
A previously unknown protein mechanism has now been described by new research. This provides an exceptionally detailed understanding of how nature works, and it can also provide the ability to control nature -- in this case, it is about how coagulated blood can be dissolved, and this can lead to treatment of diseases carrying a risk of blood clots.
