俄亥俄州立大学韦克斯纳医学中心和医学院、犹他大学和埃克塞特大学(英国)的一项新研究证实了之前的开创性研究,即沉思(过度思考)可以通过一种名为专注于沉思的认知行为疗法(RF-CBT)的干预来减少。此外,功能磁共振成像技术的使用使研究人员能够观察到与过度思考相关的大脑连接的相关变化。
阅读全文约翰斯·霍普金斯医学院的研究人员表示,在一项旨在探索大麻主要精神活性化合物四氢大麻酚对青少年大脑影响的小鼠研究中,他们发现小胶质细胞(一种特殊的大脑免疫细胞)的结构发生了变化,这可能会加剧精神分裂症的遗传易感性。这项研究结果于10月25日发表在《自然通讯》上,为吸烟或食用大麻产品的青少年大脑发育风险增加了越来越多的证据。

阅读全文卡罗林斯卡研究所的研究人员在分子精神病学上发表的一项研究中报告称,阿尔茨海默病发展过程的早期阶段是大脑中被称为海马体的部分的代谢增加。这一发现为早期干预开辟了新的潜在方法。
阅读全文After a distant star's explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months -- a phenomenon astronomers had never seen before, a Cornell-led team reports in new research published Nov.
阅读全文A team of European astronomers, co-led by researchers from the Institute of Astronomy, KU Leuven, used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atm
阅读全文In the geological past, several groups of crocodiles evolved towards a morphology adapted to marine life. However, the extent of these adaptations and their evolutionary trajectories remained unknown. An exhaustive study of their morphology by a scientifi
阅读全文Once a favored food of grazing dinosaurs, an ancient lineage of plants called cycads helped sustain these and other prehistoric animals during the Mesozoic Era, starting 252 million years ago, by being plentiful in the forest understory. Today, just a few
阅读全文The discovery of 27 avian footprints on the southern Australia coast -- dating back to the Early Cretaceous when Australia was still connected to Antarctica -- opens another window onto early avian evolution and possible migratory behavior.
阅读全文A team of researchers from Nanyang Technological University, Singapore (NTU Singapore) has developed a computer program that creates realistic videos that reflect the facial expressions and head movements of the person speaking, only requiring an audio cl
