This Week In Science : A sleep apnea pill has been fast-tracked for FDA approval; the earliest evidence of surgical anesthetic detected on tools from more than 600 years ago; strange spacetime 'crystals', and much more!
A nightly pill to treat sleep apnea is on the fast track for FDA approval, after promising results in a recent phase 3 By week 26, almost 42 percent of participants taking the drug had moved into a lower severity category – and nearly 18 percent stopped experiencing obstructive sleep apnea altogether. Early surgeons used toxic compounds as anesthetic, according to a new chemical analysis of 600-year-old medical tools in China.
"This is the first time humanity has found direct chemical evidence of anesthetics on ancient surgical tools, proving that our ancestors already knew how to safely alleviate patients' pain with highly toxic herbs," says Congcang Zhao of Northwest University in China.

New experiments have revealed how bean plants can attract predatory wasps to defend them from hungry caterpillars. Common bean plants, the study found, have receptors that recognize and react to inceptin, a peptide that occurs commonly in caterpillar 'spit'. When caterpillars chew at a bean plant's leaves, it triggers a wave of immunological responses in the plant, which release volatile compounds that start 'advertising' fresh caterpillar on the wasp menu.
The tests also revealed that the compound roseoflavin could potentially work to disrupt this cancer cell shield. It's very early days, but this suggests a way to target cancer cells without interfering with vitamin B2 in healthy cells.
A wild new paper explains how bits of spacetime could actually 'crystallize' – and these crystals could then collapse into tiny "This spacetime crystal is a very peculiar and fascinating object," says physicist Daniel Grumiller of the Technical University of Vienna in Austria.
"It is a kind of intermediate state, an unstable point that can evolve in two different directions. It may simply dissolve again, leaving behind ordinary spacetime filled with freely moving particles.
"But if a tiny amount of energy is added, the evolution takes a completely different path: the inconspicuous spacetime crystal turns into a
