Lead in teeth can tell a body's tale, study finds

Science News Daily - 10 hours 31 min ago
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.

Effect of loud noises on brain revealed in study

Science News Daily - 11 hours 16 min ago
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

Science News Daily - 11 hours 16 min ago
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.

Brother of Hibiscus flower is found alive and well on Maui, Hawaii

Science News Daily - 11 hours 48 min ago
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

Science News Daily - 11 hours 49 min ago
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.

Boat noise impacts development, survival of sea hares

Science News Daily - 11 hours 51 min ago
The development and survival of an important group of marine invertebrates known as sea hares is under threat from increasing boat noise in the world's oceans, according to a new study. Sea hares usually hatch from their eggs to swim away and later feed on toxic alga but this study found that when exposed to playback of boat noise, more eggs failed to develop and those that hatched were more likely to die.
