Altmetric’s High Five – How Fossil Lucy Died and Answers to Other Mysteries (August 2016)
Welcome to the Altmetric High Five in association with the Science Council. On a monthly basis, the High Five posts examine a selection of the most popular research outputs Altmetric has seen attention for that month.
This month’s theme is solved (maybe) mysteries.
The original post can be found on the Altmetric blog. Links to all papers included can be found in the Reference section at the end.
1. Meet the Greenland shark, the longest-lived vertebrate

Our first High Five paper this month is “Eye lens radiocarbon reveals centuries of longevity in the Greenland shark (Somniosus microcephalus),” a report published in Science magazine. The paper provides evidence, through radiocarbon dating of eye tissue, that the Greenland shark is the longest-lived vertebrate known with a lifespan for female sharks of at least 272 years. The oldest among the sharks dated was nearly 400 years old.
Over 160 news outlets and 25 blogs covered the study.
The study will likely spur more research on the Greenland shark, about which we know relatively little, as well as hopefully conservation efforts for these and other long-lived vertebrates.
2. A new Earth-like planet to explore?

Our next High Five paper is “A terrestrial planet candidate in a temperate orbit around Proxima Centauri,” published in Nature this month. The paper describes an Earth-sized planet that is orbiting Proxima Centauri, the star closest to the Sun, at the “right distance for liquid water to exist.”
Nearly 160 news outlets covered the study.
3. Training the brain with virtual reality

Our third High Five paper is “Long-Term Training with a Brain-Machine Interface-Based Gait Protocol Induces Partial Neurological Recovery in Paraplegic Patients” published in Nature Scientific Reports this month. The study investigated paraplegic patients subjected to a training program including “intense immersive virtual reality training, enriched visual-tactile feedback, and walking with two EEG-controlled robotic actuators.” The study authors report neurological improvements in sensation in patients following 12 months of this kind of training.
Nearly 200 news outlets covered the study, which was also highly tweeted. News reports especially focused on the virtual reality aspect of this new study.
4. Lucy fell out of a tree

Our next High Five paper is “Perimortem fractures in Lucy suggest mortality from fall out of tall tree,” published in Nature this month. The study provides evidence that the fossil ‘Lucy’ (Australopithecus afarensis) died from a “vertical deceleration event or impact following a fall from considerable height that produced compressive and hinge (greenstick) fractures in multiple skeletal elements.”
Over 160 news outlets covered the study.
5. Can Instagram tell us if a person is depressed?

Our final High Fiver paper is “Instagram photos reveal predictive markers of depression,” submitted to arXiv.org in August 2016. The authors write, “[u]sing Instagram data from 166 individuals, we applied machine learning tools to successfully identify markers of depression.” The researchers found that “[p]hotos posted by depressed individuals were more likely to be bluer, grayer, and darker.” Depressed individuals posted images with black and white filters more often.
Nearly 100 news outlets covered the study.
