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.
The neurotransmitters GABA and glutamate have complementary roles -- GABA inhibits neurons, while glutamate makes them more active. Published 22nd July in PLOS Biology, researchers led by Roi Cohen Kadosh and George Zacharopoulos from the University of Oxford show that levels of these two neurotransmitters in the intraparietal sulcus of the brain can predict mathematics ability. The study also found that the relationships between the two neurotransmitters and arithmetic fluency switched as children developed into adults.
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.
The mathematics education can often be associated with only numeracy skills. But viewing the discipline as a cultural product--whose values differ across cultures--reveals its significance beyond numbers crunching. In this June Special Issue for ECNU Review of Education, being released as a tribute to the 14th International Congress on Mathematical Education, Dr. Qiaoping Zhang and Dr. Wee Tiong Seah, with other researchers from across Asia and Oceania, share their latest research and developments on values in mathematics education.
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.
In the vicinity of black holes, space is so warped that even light rays may curve around them several times. This phenomenon may enable us to see multiple versions of the same thing. While this has been known for decades, only now do we have an exact, mathematical expression, thanks to Albert Sneppen, student at the Niels Bohr Institute. The result, which even is more useful in realistic black holes, has just been published in the journal Scientific Reports.
Machine learning accelerates the search for promising Moon sites for energy and mineral resources.
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.
