Research roundup: 6 cool science stories we almost missed

Summary

This article highlights six recent scientific discoveries, including cyborg cockroaches with diving suits, evidence of ancient Egyptian princesses as archers, and a companion star orbiting Betelgeuse. It also details research confirming a Medici duke died of malaria and re-evaluates the cause of death for an Incan sacrificial boy.

Key Takeaways

1. Research confirms an Incan sacrificial boy died from blunt force trauma, likely from a star-shaped mace, rather than freezing.
2. New analysis of ancient Egyptian remains suggests princesses were skilled archers, with pronounced upper limb development correlating to habitual bow use.
3. Scientists have developed amphibious cyborg cockroaches by outfitting them with a tiny diving suit that provides oxygen, enabling navigation in flooded terrain.

Credibility flag: Informative, Research-Based

Claimed Facts (8)

• This is a direct statement of a research finding presented as fact.
• This statement presents specific observations from the reanalysis of remains.
• This is a factual observation about the physical state of the remains.
• This is a conclusion drawn from the physical evidence presented as a likely scenario.
• This is a factual observation about the physical condition of the remains and its interpretation.
• This statement reports findings from a specific diagnostic imaging technique.
• This describes the methodologies used in the research, presented as factual steps.
• This presents specific findings about an individual's remains and their interpretation.

Opinions (8)

• This is a subjective statement expressing the author's sentiment about their work.
• This describes the author's editorial process and selection criteria, which is a subjective choice.
• While presented as 'known,' the belief system of the Incas is an interpretation of historical and anthropological understanding, not a directly verifiable fact.
• This statement relies on historical accounts, which are interpretations and narratives, rather than direct empirical evidence.
• This is a speculative interpretation of the observed vomiting in relation to the head injury.
• The phrase 'more likely caused by' indicates a degree of interpretation and inference rather than a definitive fact.
• This is an interpretation of the significance of the artifacts found, stating what they 'directly explain' and what they 'were not'.
• This statement expresses a potential limitation or drawback, which is an opinion on the practical implications.

Claims (8)

• While the journal is real, the claim that 'they described their findings' is a general statement that lacks specific verifiable detail within this context.
• The phrase 'concluding that the princesses were likely skilled' introduces a degree of uncertainty and interpretation that borders on unsubstantiated without further context from the paper itself.
• The assertion that 'the rest of the bones were in good condition' is a subjective assessment that lacks specific metrics for 'good condition'.
• While the identification of malaria strains is a scientific claim, the article does not provide the specific evidence or methodology for this identification, making it a claim that requires further substantiation.
• The claim of 'consistency' with archival records and prior analysis is presented without detailing the specific records or the nature of the immunological analysis, making it difficult to verify.
• The phrase 'worked quite well' is a subjective assessment of performance without specific data or metrics to support it.
• The statement 'little doubt remains' is a strong assertion of certainty that may overstate the current scientific consensus or the definitive nature of the evidence presented.
• This is a general statement about the availability and use of a product that lacks specific evidence or citation within the article.
