Believe it or not, police have a real problem with identifying suspects who are identical twins — unless you’re willing to spend a month sequencing genes, DNA samples are all but useless. They may be far more effective in the future, though, as British researchers havedeveloped a technique that melts DNA to identify what few differences exist. The team has determined that heating genes will break hydrogen bonds that form due to a person’s environment and habits. Unless the twins live eerily similar lives, those bonds will snap at different temperature points and quickly identify who’s who.
