阅读全文The researchers used publicly accessible datasets to train an explainable artificial intelligence model called iterative Random Forest to predict how efficiently CRISPR-Cas9 can edit specific DNA sequ...
阅读全文The team used differentiated stem cells - i.e. stem cells that can no longer develop into any type of tissue, but are already predetermined to form a specific type of tissue, in this case cartilage ti...
阅读全文The computerised design process begins with a 3D geometric structure composed of discrete elements called voxels. A trained generative AI system, called a conditional generative adversarial network, i...
阅读全文This new substance spontaneously binds to the outside of liposome particles when mixed with them in water. Crucially, the polymer is not recognised by the antibodies that the body can generate in resp...
阅读全文The scientists have validated the utility of the computer program by using it to screen for drugs in SARS-CoV-2 infected cells, as published last year in “Science Advances.” They also used it to fin...
阅读全文IT之家1月30日消息,英特尔官方发文,中国台湾地区医院开发了一款检测咽喉癌的App,用户只需打开App对着手机张嘴说“啊”,持续2-3秒,AI便会通过基于英特尔的硬件和软件,将声音质量与大量经过训练的数据进行比...
阅读全文幽门螺旋杆菌是可人际传播的一种常见致病菌。我国成年人幽门螺旋杆菌感染率高达40%-50%。长期幽门螺旋杆菌感染已被认定为I类人类致癌物。目前,临床治疗幽门螺旋杆菌感染的标准疗法(即,三联疗法和四联疗法)都依赖...
阅读全文与马斯克领导的Neuralink脑机接口不同,无线微创植入脑机接口NEO把电极放在大脑硬膜外,通过长期动物试验研制,不会破坏神经组织;采用了近场无线供电和传输信号,体内无需电池。此次临床应用的NEO系统软硬件由清华大...
