  • The organization of electrolytes at the air/water interface affects the structure of interfacial water and therefore numerous natural processes. It has now been demonstrated that the surface of an electrolyte solution is stratified and consists of an ion-depleted outer surface and an ion-enriched subsurface layer, jointly determining the water interfacial structure.

  • Controlling site-selectivity and reactivity in chemical reactions continues to be a key challenge in modern synthetic chemistry. Here, the authors demonstrate the assembly of amino-substituted porphyrins on a water surface into J-aggregate structures in the presence of charged surfactants.

  • The control of RNA stability is essential for gene regulation in eukaryotes. Hirayama et al. demonstrate that poly(A)-specific ribonuclease and bacterial-type poly(A) polymerase control mitochondrial mRNA poly(A) status in Arabidopsis, showing that a unique system regulating mitochondrial function operates in plants.

  • Vibrational energy transfer in water involves intermolecular coupling of O-H stretching modes, but much less is known about the role of the bending modes. Here the authors, combining static and femtosecond infrared, Raman, and hyper-Raman spectroscopy and ab initio molecular dynamics simulations, provide insight into the energy dynamics of the bend vibrations.

  • A total of 1074 patients with a history of ischemic stroke enrolled in The Recurrent Stroke Prevention Clinical Outcome (RESPECT) Study were assigned to intensive blood pressure (BP) control group (blood pressure < 120/80 mmHg) or standard blood pressure control group (blood pressure < 140/90 mmHg) and were followed up for a mean of 3.9 years. Seventy-eight first recurrent strokes occurred, including 70 ischemic stroke and 8 intracerebral hemorrhage. Intensive treatment did not change annual risk of ischemic stroke (1.74% vs. 1.75%, P = 0.999), but markedly reduced risk of hemorrhagic stroke (0.00% vs. 0.39%, P = 0.005). Beneficial effect of intensive BP control were observed for risk of hemorrhagic stroke in the patients with a history of ischemic stroke.
