contrastar

To contrast — highlighting the difference between two things ("contrastar dos estilos"), and also, more literally, to check or verify information against a source ("contrastar los datos con el informe oficial"). Both senses are common in analytical and journalistic writing.

• El artículo contrasta dos modelos económicos distintos. — The article contrasts two different economic models.
• Siempre hay que contrastar la información antes de publicarla. — You always have to verify information before publishing it.
• Su actitud tranquila contrastaba con el nerviosismo del resto. — Her calm attitude contrasted with everyone else's nervousness.

In journalism, contrastar specifically means to verify a fact against another source, not just "to look different" — a claim that hasn't been contrastada (fact-checked) is treated as unconfirmed, a stronger idea than the everyday English "contrast."
