引发新疫情的病毒对科学界而言较为陌生
随着全球监测力度加强,人类正面临越来越多此前未知或鲜为人知的病毒引发的疫情。科学家指出,像埃博拉病毒和汉坦病毒等病原体存在大量未被发现的毒株与物种,这些"病毒暗物质"可能随时突破物种屏障感染人类。文章呼吁加大对病毒多样性的研究投入,以更有效地预测和应对未来的大流行威胁。

A new paper by Thomas Bloom, Will Sawin, Carl Schildkraut and Dmitrii Zhelezov disproves a well-known conjecture in additive combinatorics. The result shows there exist arbitrarily large finite sets A of real numbers where max(|A+A|,|AA|) ≤ |A|^{2-c}. The solution was achieved by humans using methods related to an earlier AI solution to the unit distance conjecture.
