New theory to explain why sun's surface rotates slower than its core
(Phys.org)—A small team of researchers with the University of Hawaii, Ponta Grossa State University in Brazil and Stanford University has found what they believe is the reason that the surface of the sun rotates more slowly than its core. In their paper published in the journal Physical Review Letters, the team explains how they used a new technique to measure the speed of the sun's rotation at di

Don't panic—the northern lights won't be turning off anytime soon
The northern lights are nature's very own magnificent light show. They are the mesmerising end result of electrically charged particles from the sun colliding with the Earth's upper atmosphere. Though more frequently witnessed from the polar regions, the UK and other places on similar latitudes are lucky enough for the aurora borealis to occasionally grace their night sky.

Radial core heat spreader to improve Stirling radioisotope generator heat rejection
The NASA Glenn Research Center is developing the next generation of Stirling Radioisotope Generators (SRGs) to power deep space science missions. One potential technology gap is the waste heat rejection approach for higher power Stirling convertors. The previous 140W Advanced Stirling Radioisotope Generator (ASRG) used a copper alloy conduction flange to transfer heat from the convertor to the gen

The microscopic size of phytoplankton, the plant-like organisms that live in the sunlit upper ocean, belies their importance in the global environment. They provide the food source for the zooplankton that ultimately feed larger animals ranging from small fish to whales. And like plants on land, phytoplankton use carbon dioxide from the atmosphere to grow and thrive through photosynthesis, which u

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.

Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.

Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
