During the last few years,epidemiological data from many countries suggest that the incidence and prevalence of many cancers of the digestive system are shifting from the older to the younger ages,the so-called“early-onset cancer”.This is particularly evident in colorectal cancer and secondarily in other malignant digestive neoplasms,mainly stomach and in a lesser degree pancreas,and biliary *** should be emphasized that data concerning digestive neoplasms,except for those referring to the colon and stomach,could be characterized as rather *** exact magnitude of the shift in younger ages is expected to become clearer shortly,as long as relevant epidemiological data from many parts of the world would be *** most important question concerns the etiology of this phenomenon,since its magnitude cannot be explained solely by the better diagnostic methodology and the preventive programs applied in many *** existing data support the assumption that a num.e..of environ-mental factors may play a primary role in influencing carcinogenesis,sometimes from *** that have appeared in the last decades related mainly to eating habits,consistency of gut microbiome and an increase of obese people interacting with genetic factors,ultimately favor the process of *** these factors however,are not entirely sufficient to explain the age-related changes in the frequency of digestive *** of the individual effect of each of the already known factors or factors likely to be involved in the etiology of this phenomenon and studies using state-of-the-art technologies to accurately determine the degree of the population exposure to these factors are *** this article,we attempt to describe the epidemiological data supporting the age-shifting of digestive malignancies and their possible ***,we propose some measures regarding the attitude of the scientific community to this alarming phenomenon.

科学研究的目的是发现基本原理和解决实际问题。尽管人类在发现基本原理和解决实际问题上已经取得了巨大成就,但有效工具和有效科研组织模式的缺乏仍然是制约科研效率的主要瓶颈。人工智能(AI)的迅速发展为改变这种状况提供了新的可能。近年来,深度学习方法在科学研究领域大放异彩,不仅助力解决了一些核心科学问题,扩展了科学方法,也开始带动科学研究从传统的“作坊模式”转向“平台模式”。目前,我国已在人工智能驱动的科学(AI for Science)领域打下良好基础,应把握机遇,争取引领科技创新,为人类的科技发展作出贡献。

In addition to their visible motion such as swimming(e.g.,with the help ofﬂagella),bacteria can also exhibit nanomotion that is detectable only with highly sensitive instruments,and this study shows that it is possible to detect bacterial nanomotion using an AFm detection *** results show that the nanomotion characteristics depend on the bacterial strain,and that nanomotion can be used to sense the metabolic activity of bacteria because the oscillations are sensitive to the food preferences of the bacteria and the type of surrounding medium.
