Although the problem of whether fetuses are able to feel pain or not is still controversial, researchers in Spain have found that from the second trimester of pregnancy, the future baby already shows signs of pain when given a harmful stimulus or as a response to stress. The finding, the researchers argue, indicate the need to anesthetize the fetus during open fetal surgery.
Menomous Solenodon, last survivor of a branch of mammals that appeared at the time of the dinosaurs, sequenced
An article presents a draft genome of a small shrew-like animal, the venomous Hispaniolan solenodon. This unusual animal is one of the only extant venomous mammals, and it is the sole remaining branch of mammals that split from other insectivores at the time of the dinosaurs. The solenodon genome sequence revealed the answer to several evolutionary questions, such as whether the solenodon species indeed survived the meteor impact that killed the dinosaurs.
The irregular heart rhythm atrial fibrillation (AF) increases the risk of stroke and heart failure, but is often undiagnosed because of a lack of symptoms. Now, researchers have identified four short lengths of RNA (miRNAs) that show increased expression in the circulating blood of AF patients. These miRNAs could be used as potential biomarkers to predict the onset of AF disease.
A close examination of national health data indicate that the rate of biological aging appears to be more delayed for all Americans, but particularly for men, which may extend their lives. Researchers cite advancements in medicine as one possible reason for the deceleration.
Obsessive-compulsive disorder (OCD) is a complex psychological condition, and those who suffer from it experience severe reduction in their quality of life. A new study now shows that OCD sufferers need to adopt adaptive coping skills rather than the maladaptive strategies often used such as repetitive, compulsive actions or creating emotional distance from a situation, in order to effectively manage their condition.
