该研究开发了一种由电子硬件和大脑类器官（Brain organoid）组成的混合神经形态计算系统，可以执行如语音识别和非线性方程预测等人工智能（AI）任务。这一研究凸显出一种可能的方法，或可克服现有计算硬件的一些限制。

2025 年 3 月 17 日，印第安纳大学伯明顿分校郭峰团队（蔡虹威为第一作者）在 Cell 子刊 Cell Stem Cell 上发表了题为：Vascular network-inspired diffusible scaffolds for engineering functional midbrain organoids 的研究论文【1】。 该研究开发了一种受血管网络启发的可扩散支架 ...

The best freckle pens are taking over TikTok for their tone-mimicking pigments that look near identical to real spots. By definition, natural freckles are well-defined brown spots that show up in ...

A common strategy to identify and morphologically analyze neural cells is to genetically express freely diffusible cytosolic or membrane labels, such as green or red fluorescent protein (GFP or RFP).

Diffusible proteins: mostly inhibitory, but possibly attractant for some neurons, also a nerve growth factor Secreted and cell surface molecules Multimeric receptor complexes on axons or dendrites ...

This valuable study identifies a protein called adenosine deaminase-related growth factor (ADGF) as a key regulator of tip formation in the slime mold Dictyostelium discoideum. The authors ...

This cover highlights the article Multimodal mechanisms of human centriole engagement and disengagement by Kei K. Ito, Shoji Hata, Daiju Kitagawa and colleagues. The cover image depicts the centriole ...

Parthanatos is a cell death signaling pathway in which excessive oxidative damage to DNA leads to over-activation of poly(ADP-ribose) polymerase (PARP). PARP then generates the formation of large poly ...

The fragments also directly compromise synapses they encounter along the way, according to a preprint posted February 24 on bioRxiv. Specifically, tau fragments containing the microtubule binding ...

Hydrogen peroxide has a low molecular weight; therefore, the released oxygen can penetrate the dentin and break down the double bonds of the long‐chained, dark coloured chromophores within dentinal ...
