The structure showed that this molecular machine has a built-in regulatory mechanism: it can stop itself from attaching to DNA by bending a loop in its structure to block the space the DNA would usually dock onto.The work was carried out in collaboration with Carlos Fernández-Tornero's lab at the Centro de Investigaciones Biológicas in Madrid, Spain, as well as researchers at the University of ttingen, Germany and the SOLEIL synchrotron in France, where some of the structural data was obtained. Structural data was also obtained at the Petra III ring at EMBL Hamburg, on the DESY campus in Germany. A 33-year-old Racine man was arrested at his residence in the 1600 block of Holmes Avenue Tuesday, for allegedly stabbing his dog with an eight-inch-long blade after the dog bit his hand several times, according to his criminal complaint.The man, Daniel Lee Townsend, reportedly faces one count of mistreating animals and one count of disorderly conduct by use of a dangerous weapon.Police responded to the home at 10:51 p.m. Tuesday, for what they expected was civil trouble, and they reportedly found a woman living at the home crying and petting the dog and Townsend claiming that the dog had attacked him three times.


"You didn't have to stab her," the woman said, according to the police report, prompting officers to spot a wound on the dog's left hip bleeding profusely.The incident began when the Townsend and the woman were going to bed, according to the police report, and the man shoved the woman to one side of the bed, causing her to lose her balance and fall off the bed.This reportedly startled the dog to attack the man, according to the woman's statement, and she saw the dog bite Townsend and Townsend grab a fillet knife with an eight-inch blade.The woman reportedly said that she did not see if Townsend stabbed the dog before or after the incident.The woman presented the knife to police, according the report, which had the dog's blood on six inches of the blade.An officer assisted the woman in getting the dog into the woman's car so it could receive medical attention, but the report noted that the man did not assist or act with any urgency that would indicate he cared whether the dog lived or died.Police arrested the man at the residence, took him get the bite injuries checked, and then, once he was medically cleared, took him to the Racine County Jail.
