Nano Select, EarlyView.Antibacterial micro/nanorobots (MNRs) represent a breakthrough in antibacterial therapy, making precise delivery of drugs to the infection site. This review systematically summarizes the material composition, actuation, and applications of MNRs in combating biofilms and drug‐resistant infections while emphasizing the existing challenges of ...

Strictures of a microchannel impose fierce competition to select for highly motile sperm
Science Advances, 2019 Motility-based competition dynamics at microfluidic strictures suggests a sperm-selection mechanism in the reproductive tract. Investigating sperm locomotion in the presence of external fluid flow and geometries simulating the female reproductive tract ...

Regulatory mechanisms of reproduction in locusts and grasshoppers
New Plant Protection, EarlyView.Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

A review on studies of behavioural ecology of Centrobolus (Diplopoda, Spirobolida, Pachybolidae) in southern Africa [PDF]
Arthropods, 2019 Forty-two studies on fire millipedes are reviewed in which mechanisms of selection; sperm competition and cryptic female choice were studied. Approaches to: (1) quantify size dimorphism and find the selection pressures operating on the sexes, (2 ...

Pest Management Science, EarlyView.Bisexual releases are as effective as male‐only releases to control Drosophila suzukii with the sterile insect technique. Releasing sterile Drosophila suzukii males or males and females in cages led to the same degree of induced sterility in wild females.

Sperm competition risk drives plasticity in seminal fluid composition
BMC Biology, 2015 BackgroundEjaculates contain a diverse mixture of sperm and seminal fluid proteins, the combination of which is crucial to male reproductive success under competitive conditions.

Small Methods, EarlyView.Cardenolide‐functionalized extracellular vesicles enable targeted delivery of the chemotherapeutic doxorubicin to A549 lung cancer cells by binding Na+/K+‐ATPase, which is overexpressed in these cells. Surface‐modified, drug‐loaded EVs exhibit enhanced cytotoxicity compared to unmodified EVs and free drug, suggesting this system may lower the effective

The adaptive function of masturbation in a promiscuous African ground squirrel.
PLoS ONE, 2010 Studies of animal mating systems increasingly emphasize female multiple mating and cryptic sexual selection, particularly sperm competition. Males under intense sperm competition may manipulate sperm quantity and quality through masturbation, which could

Sperm competition in grey whales
Nature, 1988 SIR-Your legend for the drawing of grey whales taken from Cyall Watson's book Whales of the World, perpetuates the myth that a 'helper' male is necessary for successful mating in this species. The legend states that: "Only one male is involved in the actual mating; the other takes an upright position on the far side of the female, acting as a prop or ...
