Disagreement seems to spread online posts faster and further than agreement, according to a new study from the University of Central Florida. The finding comes from an examination of posts labeled controversial on social news aggregation site Reddit. To perform the study, the researchers analyzed a Reddit dataset that was collected by DARPA.

Tsukuba University researchers develop a scheduling algorithm that helps automated biology labs optimize their samples throughout experiments while adhering to time constraints set by perishable materials. This work may help robots more effectively process cellular assays and clinical blood tests.

It's a supply and demand problem, it's a transportation problem, it's a donor problem - and that just scratches the surface. According to the Organ Procurement and Transplantation Network, every 9 minutes a new patient is added to the organ waiting list. Every day 17 people die waiting for a kidney transplant. New research in the INFORMS journal Management Science tackles the transportation part of this problem.

An elegant new algorithm developed by Danish researchers can significantly reduce the resource consumption of the world's computer servers. Computer servers are as taxing on the climate as global air traffic combined, thereby making the green transition in IT an urgent matter. The researchers, from the University of Copenhagen, expect major IT companies to deploy the algorithm immediately.

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types. Study publishes in Nature Biotechnology.

Physicists at MIT and elsewhere have used gravitational waves to observationally confirm Hawking's black hole theorem for the first time.
