For the month of March, a variety of papers caught the media’s attention, from distracting cell phone conversations, to the devastating decline in forest elephants. Here are some of the media highlights for this month:
Have you ever wondered where your hound originated from? In a paper featured this March, researchers have identified the fossil remains of the oldest domestic canine ancestor. In this study, researchers analyzed the DNA of a 33,000 year old tooth belonging to a Pleistocene dog from central Asia. In their evaluation of the fossil, they assessed its relationship to modern dogs and wolves’, concluding the tooth was more closely related to the domestic canine.
In another study, researchers at the Cleveland Clinic have found that football players might sustain long-term brain injuries without ever having a concussion. 67 players who had never suffered a concussion underwent testing over the course of a season. The testing, which included blood sampling, brain scans, cognitive and functional assessments, screened for potential brain damage among the participants. The researchers searched for S100B in the blood, an antibody linked to brain damage. This antibody was found in many of the participants, with the highest levels belonging to the players with the most hits.
Have you ever found yourself distracted when a co-worker is on a phone call? In an eye-catching paper published this month, PLOS ONE authors examined the effects on attention and memory when listening to cell phone conversations, versus two-sided conversations. The participants were assigned a task while two conversations were in progress, one on a cell phone, and another between two individuals. After the task was completed, the participants were assigned a recognition memory task and questionnaire measuring the distracting nature of the conversation. The participants who overhead the cell phone conversation measured it as much more distracting compared to the two-sided conversation.
And in a fourth study capturing the attention of many, researchers have examined the decline of forest elephants in Central Africa. The study concludes that forest elephants are being poached at increasing rates. Poaching, in addition to the human population rise and the absence of anti-poaching law enforcement, is contributing to the elephant’s population decline. The analysis revealed that 62 percent of the African forest elephants have been eliminated in the last decade due to poaching.
These four papers are just a taste of the variety of papers published this month. For more research headlines, visit our site here.
