封面圖上展示的是一種名為冠藍(lán)鴉的鳥,與其他鴉科鳴禽類似,這種鳥以其令人印象深刻的認(rèn)知能力而聞名,這可能是因?yàn)樗鼈兊拇竽X相對較大。冠藍(lán)鴉能夠解決一些復(fù)雜的問題,學(xué)習(xí)許多發(fā)聲方式,甚至模仿其他物種。一項(xiàng)新研究測試了包括冠藍(lán)鴉在內(nèi)的23 種鳥類,發(fā)現(xiàn)聲音學(xué)習(xí)能力更強(qiáng)的物種其解決問題的能力也更強(qiáng),大腦也更大。
Blue jays, similar to othercorvid songbirds, are knownfor their impressive cognitiveabilities, presumably due to theirrelatively large brains. They cansolve complex problems, learnmany vocalizations, and evenmimic other species. A newstudy tested 23 avian species,including the blue jay, anddiscovered that species withgreater vocal learning abilitieshave greater problem-solvingabilities and bigger brains.

封面插圖描繪了一幅人體形態(tài)的熱點(diǎn)圖拼貼畫(紅色和藍(lán)色方塊)?;A(chǔ)數(shù)據(jù)來自AlphaMissense,這是一種人工智能模型,用于為所有人類蛋白質(zhì)編碼基因中每種可能的錯(cuò)義變異生成致病性評分。目前,大多數(shù)人類錯(cuò)義變異的臨床意義尚不清楚,這些預(yù)測數(shù)據(jù)可以作為一種社會(huì)資源以供研究。

封面圖片拍攝的是印度夏季的一幕,展現(xiàn)了地球氣候變暖如何挑戰(zhàn)人類的耐力極限。除了對身體自我冷卻的能力產(chǎn)生威脅外,全球變暖還促進(jìn)了介體及水媒傳染病的擴(kuò)散,并可能暴露其他病原體。本期特刊探討了對人類健康的威脅因素,以及我們應(yīng)該如何緩和這些威脅。
A summer scene in Indiacaptures how Earths warmingclimate is pushing the limitsof human endurance. Besidesstraining the bodys ability tocool itself, global warming isfostering the spread of vectorandwaterborne diseases and isperhaps bringing other pathogensout of hiding. This special issueexamines the threats to humanhealth and how they can bemitigated.

封面圖展示的是藝術(shù)家利用藝術(shù)手法描繪的一個(gè)沉積物核心,其中包括對使用古代DNA 研究的生物體的描繪,這些古代DNA包含了猛犸象、桑樹、古人類,以及來自古生態(tài)系統(tǒng)的花粉。古代DNA 讓我們得以一睹這些生物體和許多其他生物體及其分支的過去,這對我們理解進(jìn)化、生態(tài)變化,甚至我們自己的歷史產(chǎn)生了深遠(yuǎn)影響。
