据彭博社记者马克·古尔曼在Power On通讯中透露,苹果内部对传闻中的平价版MacBook给出“超高性价比”评价,预计发布后将吸引大量微软Win11、谷歌ChromeOS用户转向Mac阵营,同时有望让无电脑的iPhone用户购入首台Mac。目前苹果尚未公布该产品售价,参考在售MacBook Air 999美元起售价,平价版MacBook定价将明显更低,同时为避免与iPad产品线冲突,合理定价区间预计在599-799美元(约4115-5489元人民币),定位介于iPad Air与MacBook Air之间。(IT之家)

We found that when AI is designed as a tutor that asks questions instead of simply giving answers – and when students are also required to explain their reasoning to classmates – the technology can support learning rather than replace it.

While Sanger sequencing was highly accurate and less labor-intensive than its predecessors, it still required the use of radioactive reagents and manual sequence recording. In 1986, Leroy Hood’s lab at Caltech replaced the radiolabeled ddNTPs with fluorescently labeled nucleotides, using fluorophores that emitted different colors of light for each base. They were now able to run the products of all four reactions on the same gel and have a computer read the sequence by detecting the color of each fluorescent signal as fragments passed through a laser beam.
