Narrative cave art in Indonesia by 51,200 years ago.

Previous dating research indicated that the Indonesian island of Sulawesi is host to some of the oldest known rock art. That work was based on solution uranium-series (U-series) analysis of calcite deposits overlying rock art in the limestone caves of Maros-Pangkep, South Sulawesi. Here we use a novel application of this approach-laser-ablation U-series imaging-to re-date some of the earliest cave art in this karst area and to determine the age of stylistically similar motifs at other Maros-Pangkep sites.

Turmeric extract gel and honey in post-cesarean section wound healing: A preliminary study.

Background: Delivery by cesarean section (SC) increases the risk of a surgical site infection (SSI). Therapy from health services and complementary therapy reduce the risk of infection and accelerate the wound-healing process. This study compared wound healing after SC with a turmeric extract gel and original Trigona honey.

Factors Associated with Psychosocial Symptoms Experienced by Students in Response to COVID-19 Pandemic: A Multivariate Analysis.

The COVID-19 pandemic has significantly impacted many sectors, including the education sector. After in-person school activities were suspended due to the pandemic, a number of educational institutions in Indonesia reported concerns in implementing online learning due to the institutions' unpreparedness. This issue may potentially induce mental health disorders among students and triggers long-term stress.

Surgical amputation of a limb 31,000 years ago in Borneo.

The prevailing view regarding the evolution of medicine is that the emergence of settled agricultural societies around 10,000 years ago (the Neolithic Revolution) gave rise to a host of health problems that had previously been unknown among non-sedentary foraging populations, stimulating the first major innovations in prehistoric medical practices. Such changes included the development of more advanced surgical procedures, with the oldest known indication of an 'operation' formerly thought to have consisted of the skeletal remains of a European Neolithic farmer (found in Buthiers-Boulancourt, France) whose left forearm had been surgically removed and then partially healed. Dating to around 7,000 years ago, this accepted case of amputation would have required comprehensive knowledge of human anatomy and considerable technical skill, and has thus been viewed as the earliest evidence of a complex medical act.
