Structural Variation in Whistle Patterns of Two Coastal Dolphin Species Co‐Occurring in the Southern Israeli Mediterranean Sea

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

Group‐Specific Variation in Heterodyne Frequencies of Biphonic Calls in Resident (R‐Type) Killer Whales Orcinus orca ater

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term

Description, Detection, and Classification of Hawaiian Monk Seal Vocalizations Through Deep‐Learning Methods: Biological and Conservation Applications

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The Hawaiian monk seal is a phocid Carnivore endemic to the Hawaiian Archipelago. This species was thought to be silent under water until the recent discovery that mature males produce at least six distinct calls year round, typically in bouts of two or more, with sound production linked to reproductive status.

Chilean Dolphins (Cephalorhynchus eutropia) Produce Both Narrowband High‐Frequency and Broadband Clicks

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Most dolphin species produce broadband biosonar clicks for echolocating prey, and whistles and burst‐pulsed calls for communication purposes. Seven dolphin species were previously reported to only produce clicks of a narrowband high‐frequency (NBHF) type, very similar to the clicks produced by porpoises.

Ultrasound‐Actuated Gene Editing in Human Kidney Organoids

Advanced Science, Volume 13, Issue 49, 3 September 2026.
Peptide‐stabilized nanoemulsions enable spatially controlled, ultrasound‐triggered delivery of gene‐editing proteins deep within human kidney organoid tissues. Focused acoustic pulses drive droplet vaporization, propelling cargo into target renal cells while preserving native tissue microarchitecture. This non‐viral platform improves both the depth and
