A Chinese surveillance firm is tracking the movements of more than 2.5 million people in the far-western Xinjiang region, according to a data leak flagged by a Dutch internet expert.

When one of New Orleans' most cherished parades rolls next month, float riders -- African-American and white -- will greet the screaming throngs wearing lofty feather headdresses, crinkly grass skirts and the sort of black face paint that most anywhere else might draw gasps and cries of racism.

New York Yankees pitcher CC Sabathia, a Cy Young Award winner and the major league's active leader in strikeouts and innings pitched, confirmed Saturday this will be his final season.

Researchers report that a new nuclear medicine tracer may allow better diagnosis of acute venous thromboembolism (VTE). Acute VTE is a disease that includes deep-vein thrombosis and its complication, pulmonary embolism, which can be fatal.

“We need to know more about the networks and members of groups that spread false information and target individuals," said Jonathan Albright of Columbia University.

Researchers have developed a new rapid prototyping technique for fluoropolymer microfluidic device. This microfluidic device was fabricated by two steps: (1) cutting commercially available fluoropolymer films using a computer controlled cutting plotter and (2) heat pressing fluoropolymer films using a heat press machine. The technique provides a simple, low-cost avenue to create fluoropolymer microfluidic channels for handling strong organic solvents.

By analyzing the network connections between 47,000 films on IMDb, researchers found the most influential films ever made. Christopher Intagliata reports.

Researchers have engineered a new fabric from synthetic yarn with a carbon nanotube coating that is activated by temperature and humidity, releasing heat in warm humid conditions and trapping heat when conditions are cool and dry.
