Twitter revises rules for threats, conduct

Twitter has revised its rules to emphasize that it will suspend or ban users who issue violent threats or espouse hateful conduct, at a time when critics have called for the social media service to adopt a harder line against extremist groups. The new policy released Tuesday says Twitter won't tolerate accounts deemed to be primarily aimed at inciting harm toward others on the basis of race, religion or other factors. Twitter and other social media sites have come under increasing pressure from politicians and other critics who say militant extremists are using the Internet to recruit members and promote their violent agendas.

Big bounce back for consumer confidence

Consumer confidence rebounded more than forecast in December as Americans grew more optimistic about the current state of the economy and job market. The Conference Board's sentiment index climbed to 96.5 from a revised November reading of 92.6 that was higher than previously estimated, the New York-based private research group said Tuesday. The combination of a strong labor market and cheap fuel costs have buoyed households' finances, giving them the wherewithal to purchase everything from cars to clothing and holiday gifts. Faster growth in wages would usher in bigger gains in confidence and probably provide another boost to consumer spending, the biggest part of the economy. The group's report is in sync with the University of Michigan's final reading for December. That gauge climbed to 92.6, the highest since July.

KaloBios to appeal decision by Nasdaq

KaloBios, the biotech company formerly run by Martin Shkreli, says that it is appealing a decision by Nasdaq to delist the company. San Francisco-based KaloBios was notified last week that Nasdaq would move to delist the company's stock because of Shkreli's arrest and several other issues. Shkreli was charged with securities fraud earlier this month. KaloBios subsequently fired him as CEO and he resigned from its board. He became infamous earlier this year after another company he led, Turing Pharmaceuticals Inc., hiked the price of a lifesaving drug by 5,000 percent. He resigned as CEO of Turing following his arrest.

Macy's issues recall for designer frying pans

Macy's is recalling two Martha Stewart brand frying pans after customers said small metal discs popped off the pans and caused bruises, burns and welts. The U.S. Consumer Product Safety Commission said Tuesday that there were seven reports of metal discs flying off the frying pans and three reports of injuries. The metal discs cover the rivets that attach the pan to the handle. The 8-inch and 10-inch frying pans were sold as part of a Martha Stewart Collection 10-piece stainless steel cookware set. The sets cost about $170 and were sold at Macy's stores and its website for four years until September. The sets were also sold for $90 at shops on military bases. The CPSC said customers should stop using the pans and return them to Macy's for a store credit. Those that bought them at military bases can return them at those stores for a refund. More than 120,000 sets are part of the recall, the CPSC said.

Gambling regulators watch newspaper sale

The sale of Nevada's largest newspaper to the family of billionaire casino-mogul Sheldon Adelson has gambling regulators watching. Nevada Gaming Control Board Chairman A.G. Burnett confirmed Tuesday the agency is monitoring reports about the recent $140 million sale of the Las Vegas Review-Journal to the Adelson family including questions raised about reporters being assigned to investigate a judge overseeing a lawsuit against Adelson and his Las Vegas Sands Corp. Burnett says the board's agents regularly monitor gambling companies and licensees are bound by state regulations barring them from engaging in anything that "might reflect discredit on the state." He says there's nothing prohibiting a casino owner from buying a newspaper.
