Some reports from 2017 hint at potentially big discoveries — if the research holds up to additional scientific scrutiny.
Putting the squeeze on hydrogen gas turned it into a long-elusive metal that may superconduct, Harvard University physicists claimed (SN: 2/18/17, p. 14). A diamond vise, supercold temperatures and intense pressure made the element reflective — a key property of metals. But other researchers in the field don’t buy it; one experiment with a slew of caveats isn’t enough to confirm the claim, those scientists say.
The skeleton of a 10th century Viking woman buried in full warrior regalia has scientists sparring over women’s roles in Viking society (SN: 10/14/17, p. 6)
