TLR7 Mediates HIV‐1 Tat‐Induced Cellular Senescence in Human Astrocytes

open access: yesAging Cell, Volume 24, Issue 7, July 2025.
Once internalized into endolysosomes, HIV‐1 Tat interacts and activates TLR7, causing endolysosome damage. Such interaction between HIV‐1 Tat and TLR7 also leads to a senescence‐like phenotype in astrocytes, including cell cycle arrest, elevated levels of p21 and p16 proteins, increased SA‐β‐gal activity, and enhanced secretion of SASP factors ...

Cranial Arterial Perfusion of the Tympanic Bullae Region in Llamas (Lama glama): Anatomic Features and Anomalies

open access: yesAnatomia, Histologia, Embryologia, Volume 54, Issue 4, July 2025.
ABSTRACT The tympanic bulla of South American camelids is a unique multi‐compartmental structure with an internal architecture resembling that of honeycomb. This unique configuration creates surgical challenges for the treatment of refractory otitis media cases in llamas (Lama glama).

Prey Capture Outside of the Web? Observational Evidence of a Novel Form of Prey Capture in a Cave Orb Web Spider

open access: yesEthology, Volume 131, Issue 7, July 2025.
It is currently not known how the European cave orb spider Meta menardi (d) catches the non‐flying prey, which makes up approximately half of its diet. Our observations in winter and summer from caves in the United Kingdom offer support to the radius tripwire hypothesis (a) over the off‐web hunting hypothesis (b) and the prey slip hypothesis (c ...

Decryption of Amphipod Cryptic Species: Ecological Differentiation of Syntopic Lineages of a Gammarus Species Complex

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Cryptic species represent an ever‐increasing proportion of discovered biological diversity. Thus, the number of observations of cryptic species co‐occurring in syntopy also increases, raising the question of mechanisms facilitating this phenomenon.

REFUGE AND THE WILDED CLASSROOM: FIGURE, PRACTICE, SPACE

open access: yesGerman Life and Letters, Volume 78, Issue 3, Page 321-341, July 2025.
ABSTRACT University teaching in a context of escalating planetary crisis requires new approaches to pedagogical encounter. Reconceptualising the university classroom as a potential refuge from polycrisis, we identify symptoms and effects of the academic‐industrial complex and ‘fast academia’ in our practice, and we develop ways to take refuge from ...
