question:  Why was Mitchell irritated that the story on the virus for headaches had been leaked to the newspapers?
context: Our reputations don't go outside our own fields," Mitchell said. No one knew whether his Theory of Spatium was correct or not because no one had yet been able to frame an argument with it. The government took up a lot of his time using him as the symbol of the Ideal Scientist to help recruit Science and Engineering Cadets. For the past seven years Macklin—who was the Advanced Studies Department of Firestone University—had been involved in devising a faster-than-light drive to help the Army reach Pluto and eventually the nearer stars. Mitchell had overheard two coeds talking and so knew that the project was nearing completion. "He's always treated me like dirt," Ferris said heatedly. "Doctor, we understand you have severe headaches," Mitchell said. "Doctor," Mitchell said, "what would you say the most common complaint of man is?" "I would have said the common cold," Macklin replied, "but I suppose from what you have said you mean headaches." "Aspirins would still be used to reduce fever and relieve muscular pains," Mitchell said. "There are a number of different causes for headaches—nervous strain, fatigue, physical diseases from kidney complaints to tumors, over-indulgence—but there is one effect of all of this, the one real cause of headaches," Mitchell announced. "The pressure effect caused by pituitrin in the brain," Mitchell said eagerly. "The virus," Ferris explained, "can easily be localized and stabilized. A colony of virus in the brain cells will relax the cerebral vessels—and only the cerebral vessels—so that the cerebrospinal fluid doesn't create pressure in the cavities of the brain." "On rats, on chimps...." Unless we can produce quick, conclusive and dramatic proof of our studies we can get no more financial backing. When I start making slips like that it means another attack of migraine. "When your heart stops, your blood pressure goes to its lowest point," Mitchell said.
output:  He felt it was too early to release without verified results.
options:  He feared the virus was counteractive.  He feared that Macklin's wife would be angry  He felt it was too early to release without verified results.  He feared that the government would shut their project down.
