If you've ever tried to untangle a pair of earbuds, you'll understand how loops and cords can get twisted up. DNA can get tangled in the same way, and in some cases, has to be cut and reconnected to resolve the knots. Now a team of mathematicians, biologists and computer scientists has unraveled how E. coli bacteria can unlink tangled DNA by a local reconnection process. The math behind the research could have implications far beyond biology.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/f7KdHd9ciF8" height="1" width="1" alt=""/>Thu, 05 Oct 2017 10:27:29 EDThttps://www.sciencedaily.com/releases/2017/10/171005102729.htmhttps://www.sciencedaily.com/releases/2017/10/171005102729.htmWhat is STEM education?

Students from families with little interest in math benefit more from a school intervention program that aims at increasing math motivation than do students whose parents regard math as important. A study indicates the intervention program has a "Robin Hood effect" which reduces the "motivational gap" between students from different family backgrounds because new information about the importance of math is made accessible to underprivileged students.<img src="http://feeds.feedburner.com/~r/sciencedaily/computers_math/mathematics/~4/1HdvciZVGYQ" height="1" width="1" alt=""/>Wed, 09 Aug 2017 07:36:29 EDThttps://www.sciencedaily.com/releases/2017/08/170809073629.htmhttps://www.sciencedaily.com/releases/2017/08/170809073629.htmNew model for bimolecular reactions in nanoreactors

Quantum technology is seen as an important future-oriented technology: smaller, faster and with higher performance than conventional electronics. However, exploiting quantum effects is difficult because nature's smallest building blocks have properties quite distinct from those we know from our everyday world.

Plant diseases pose a serious threat to global food security, especially in developing countries, where millions of people depend on consuming what they harvest. In sub-Saharan Africa, one plant disease in particular -- maize lethal necrosis -- is ravaging one of the region's preferred crops for food, feed and income.
