China contains some of the world's greatest diversity of Apiaceae (Umbelliferae), with ten endemic genera. Our previous investigation into the phylogenetic relationships of Chinese Apiaceae subfamily Apioideae, based exclusively on nrDNA ITS sequences, revealed several major clades heretofore unrecognized in the subfamily and confirmed the phylogenetic placements of five endemic genera. To furt...

A Balaton déli partmelléke és a háttérterületén emelkedő Külső-Somogy dombvidék célzott flóra- vegetációkutatása eredményeképp jelen közleményben 230 edényes növénytaxon feltérképezett előfordulási adatait mutatom be. Növényföldrajzi szempontból kiemelkedő jelentőségű Dél-Dunántúlról eddig ismeretlen Vicia sparsiflora előkerülése. E faj lösz dombhátain jellemző más xerotherm tölgyes elemek (Car...

The UK Royal Society of Chemistry has recently honored several outstanding scientists in its 2016 prizes and awards scheme. We feature some of the awardees who have recently published their work in Angewandte Chemie or its sister journals. Ian J. S. Fairlamb (University of York) is the recipient of a Corday–Morgan Prize, which is awarded to individuals under the age of 40 for their contribution...

If you are one who seeks out the Amateur Scientist section in the Scientific American each month for the beauty of the illustrations and ideas presented for the young investigator, you may enjoy this latest addition to the literature illustrating in an applied manner some electronic devices for instrumentation in the behavioral sciences. The investigator working alone in a small laboratory, wit...

Sometimes, a scientific development that might be expected to trigger media frenzy and noisy protest fails to do so. One example was the cloning of Dolly the sheep at the Roslin Institute near Edinburgh, Scotland, in 1996. Given the science fiction background, this event could easily have provoked widespread public alarm and hostility. Dolly's predominantly reasonable reception owed a good deal...

Chlorthalidone (CTD) is the best diuretic for the treatment of hypertension, both in blood pressure–lowering efficacy and, most importantly, in prevention of hypertensionrelated morbidity and mortality. Despite this fact, hydrochlorothiazide (HCTZ) has been and continues to be by far the most frequently prescribed diuretic in the United States.1 Even among patients with resistant hypertension, ...

The influences of a geographical location on floristic composition, horizontal structure, and biomass of the herb layer in pine and mixed pine forest communities along climatic and pollution gradients in East Germany, Poland, and Belarus were determined. Phytosociological records were collected in permanent plots in May 1995. Each record covered an area of 400 m2. The floristic composition of t...
