By generating a progressive series of holograms, scientists can watch sperm move and look for structural anomalies that make them less viable, helping to improve odds during in vitro fertilization.
Researchers find that a non-invasive ultrasound treatment dramatically reduces the sperm count of rats, but aren't sure if it's reversible.
When it comes to detecting cancer, ultrasound is simply too low-res to compare with CT scans and MRIs. Up the resolution, though, and the less expensive, radiation-free alternative could become an ideal alternative.
