It has recently been shown that incident particles, neutrons, can initiate the freezing in a supercooled water volume. This new finding may have ramifications for the interpretation of both experimental data on the nucleation of laboratory samples of supercooled water and perhaps more importantly on the interpretation of ice nucleation involved in cloud physics. For example, if some fraction of the cloud nucleation previously attributed to dust, soot, or aerosols has been caused by cosmogenic neutrons, fresh consideration is required in the context of climate models. Moreover, as cosmogenic neutrons, most being muon-induced, have much greater flux at high latitudes, estimates of ice nucleates in these regions may be larger than required to accurately model cloud and condensation properties. This discrepancy has been pointed out in IPCC reports. Our paper discusses the connection between the new concept of neutrons nucleating supercooled water and the need for a new source of nucleation in high latitude clouds, ideally causing others to review current data, or to analyse future data with this idea in mind. .

骨关节炎(osteoarthritis,OA)是常见的关节疾病。目前还没有能够同时防止关节退化和减少疼痛的治疗方法。有证据表明软骨细胞中存在电压门控钠通道(voltage gated sodium channels,VGSCs),但它们在软骨细胞和OA中的表达和功能仍不清楚。该研究发现,Nav1.7作为一个与OA相关的VGSCs,人OA软骨细胞以0.1~0.15个/μm2和350~525个通道/细胞的密度表达功能性Nav1.7。在通过基因操作抑制Nav1.7的一系列小鼠模型上发现,表达在背根神经节(dorsal root ganglion,DRG)神经元中的Nav1.7参与疼痛的调控,而表达在软骨细胞中的Nav1.7调节OA进程。使用选择性或临床常用的泛Nav通道阻断剂,可显著改善结构性关节损伤,并减轻OA疼痛。Nav1.7阻断剂调节细胞内Ca2+信号和软骨细胞的分泌组,进而影响软骨细胞生物学和OA进程。该研究证实,Nav1.7为一个新发现的、在软骨细胞表达的OA相关VGSCs,可作为具有双重靶点特性的用于治疗OA和镇痛的非阿片类镇痛药。
