The climbing milkweed discovered and named by Alexander Krings has tiny, clustered flowers
A new species of climbing milkweed has been named by Alexander Krings, curator of the North Carolina State University Herbarium (also NCSC, its international Index Herbariorum abbreviation). The species - Gonolobus tenuisepalus Krings - was first collected in the tropical rainforests of southern Costa Rica while Krings was a graduate student in the Department of Forestry.
"The flowers are tiny (about 6-8 millimeters in diameter), purplish to dark brownish-red and borne in very dense, umbellate clusters," said Krings. "Although a number of congenerics occur in Costa Rica, its apparently closest relative is known from Mexico. Based on the mildly fetid fragrance, it is likely pollinated by flies."
Climbing milkweeds constitute one of the most species-rich and interesting groups of vines in the world. Highly advanced, members exhibit a startling array of highly modified flowers. Pollen is borne in removable sacs called pollinia - a trait that has evolved in only one other plant family: the orchids.

In two experiments performed at the free-electron laser FLASH in Hamburg a cooperation led by physicists from the Heidelberg Max Planck Institute for Nuclear physics (MPIK) demonstrated strongly-driven nonlinear interaction of ultrashort extreme-ultraviolet (XUV) laser pulses with atoms and ions. The powerful excitation of an electron pair in helium was found to compete with the ultrafast decay, which temporarily may even lead to population inversion. Resonant transitions in doubly charged neon ions were shifted in energy, and observed by XUV-XUV pump-probe transient absorption spectroscopy.
An international team led by physicists from the MPIK reports on new results for efficient two-electron excitations in helium driven by strong and ultrashort...
An international research group has observed new quantum properties on an artificial giant atom and has now published its results in the high-ranking journal Nature Physics. The quantum system under investigation apparently has a memory - a new finding that could be used to build a quantum computer.
