Emotional Mirror Neurons in Rats

Emotional Mirror Neurons in Rats

Researchers from the Netherlands Institute for Neuroscience have demonstrated that specific neurons in the rat brain are active both when a rat experiences pain itself and when it observes another rat in pain. The results, published today in Current Biology, suggest that sharing the emotions of others is a common mammalian trait.

Congenital Heart Disease and Lapses in Care

Medical advancements over the past 20 years have allowed more people with congenital heart disease (CHD) to survive into adulthood. For these individuals, routine surveillance and follow-up care by a cardiologist are critically important. However, a new study shows lapse in care is prevalent among CHD survivors by age five, with nonwhites demonstrating elevated risk. Medicaid patients and those with less severe diagnoses also had an increased risk for lapse in care.

However, a new paper suggests this approach could result in problems if the native species ever faces their invasive foes again.

How Whip Spiders Smell Their Way Home

Whip spiders, or amblypygids, are arachnids, but only six of their eight legs are for walking. The front two are elongated sensory structures that process, among other things, smells. Whip spiders use these sensory legs to sniff their way back home after a night of hunting.
