Breakthrough observation of real-time protein translocation by SecYEG-SecA complex
Nara Institute of Science and TechnologyPeer-Reviewed Publication
Protein translocation across cellular membranes is crucial for moving proteins to specific locations and their extracellular secretion. Recently, researchers from Japan have used high-speed atomic force microscopy to observe SecYEG-SecA complex-mediated bacterial protein translocation in real-time for the very first time. Their study revealed how energy-driven conformational changes in SecA regulate protein movement across the membrane, offering new insights into mechanisms underlying protein transportation and showcasing the potential for several applications in pharmacy and medical science.

Artificial sensory neurons: Bridging biology and technology for next-generation intelligent systems
Shanghai Jiao Tong University Journal Center
The rise of artificial intelligence (AI) has transformed industries like healthcare, transportation, and manufacturing. However, the traditional von Neumann architecture limits computational speed and energy efficiency due to the separation of computing and storage units, making it less suitable for energy-sensitive applications like edge computing and the Internet of Things (IoT). Brain-inspired computing, modeled on biological neural networks, offers a solution through efficient parallel processing, addressing these limitations.

Are we still primitive? How ancient survival instincts shape modern power struggles
Taylor & Francis GroupBook Announcement
The evolutionary roots of human dominance and aggression remain central to social and political behaviour, and without conscious intervention these primal survival drives will continue to fuel inequality and division.

Near-complete skull discovery reveals ‘top apex’, leopard-sized “fearsome” carnivore
Taylor & Francis GroupPeer-Reviewed Publication
A rare discovery of a nearly complete skull in the Egyptian desert has led scientists to the “dream” revelation of a new 30-million-year-old species of the ancient apex predatory carnivore, Hyaenodonta.

Marine mystery solved: How anemonefish avoid stings from their sea anemone hosts
Okinawa Institute of Science and Technology (OIST) Graduate UniversityPeer-Reviewed Publication
The clownfish-anemone living arrangement is one of the most widely recognized examples of symbiosis. Researchers have made a breakthrough in understanding how anemonefish can live safely among sea anemones without being stung by their venomous tentacles, solving a century-long mystery. Scientists at the Okinawa Institute of Science and Technology (OIST) and their international collaborators have discovered that anemonefish have evolved to maintain very low levels of sialic acid in their skin mucus to avoid triggering the release of nematocysts (stinging cells) in their sea anemone hosts. The researchers found that sea anemones also lack these sugar compounds in their own mucus, likely to avoid stinging themselves. Their findings, published in the journal BMC Biology, suggest anemonefish might be using a similar protective strategy to their hosts.

Multilevel stressors and systemic and tumor immunity in Black and White women with breast cancer
JAMA NetworkPeer-Reviewed Publication
About The Study: The findings of this cross-sectional study of Black and white women with breast cancer suggest that perceived stress, perceived inadequate social support, perceived racial and ethnic discrimination, and neighborhood deprivation were associated with deleterious alterations to the systemic and tumor immune environment, particularly for Black women. Understanding biology as a possible mediator of cancer health disparities may inform prevention and public health interventions.
