Unlocking the mystery of the fruit fly's internal compass

For decades, researchers had a theory about how an animal's brain keeps track of where it is relative to its surroundings without outside cues – like how we know where we are, even with our eyes closed

Insights into bacterial coexistence in fungal cells

An organism as a tenant in another - in biology, this often works quite well. ETH researchers have now shed light on how such a partnership of a cell in a cell can establish.

Key RNA pathway controlling DNA packaging and cancer progression

Inside every cell, inside every nucleus, your continued existence depends on an incredibly complicated dance. Proteins are constantly wrapping and unwrapping DNA, and even minor missteps can lead to cancer.

Study uncovers how listeria monocytogenes survives in nutrient-poor environments

The detection tests commonly used to check for the absence of microbes in hospitals or the agri-food industry are based on microbial growth, i.e. the laboratory cultivation of microorganisms from a sample to be checked.

Scientists overcome major challenge in gene therapy and drug delivery

Imagine trying to poke a hole in the yolk of a raw egg without breaking the egg white. It sounds impossible, but researchers at the University of California San Diego have developed a technology that performs a similarly delicate task in living cells. They created an array of nanopillars that can breach the nucleus of a cell - the compartment that houses our DNA - without damaging the cell's outer membrane.

CheekAge can accurately predict the risk of mortality, study shows

We don't all age at the same rate. But while some supercentenarians may age exceptionally slowly due to winning the genetics jackpot, a plethora of behavioral and lifestyle factors are known to speed up aging, including stress, poor sleep, poor nutrition, smoking, and alcohol.

Scientists uncover role of Wnt in kidney formation

A group of essential signaling molecules known as the Wnt pathway emerged early in the evolution of multicellular life. Scientists have been studying Wnt actions for four decades to comprehend its complex roles in development and disease.

Advanced brain mapping reveals neuronal subtypes and their connections

Scientists at the Salk Institute are unveiling a new brain-mapping neurotechnology called Single Transcriptome Assisted Rabies Tracing (START). The cutting-edge tool combines two advanced technologies - monosynaptic rabies virus tracing and single-cell transcriptomics - to map the brain's intricate neuronal connections with unparalleled precision.

Understanding gametogenesis mechanisms in budding yeast

Sexual reproduction, a common mode of reproduction among numerous species, involves gametogenesis in which offspring are produced through fertilization, conjugation, or mating.

Scientists unravel the process of pore formation in cells

The formation of pores by a particular protein, gasdermin D, plays a key role in inflammatory reactions. During its activation, an inhibitory part is split off. More than 30 of the remaining protein fragments then combine to form large pores in the cell membrane, which allow the release of inflammatory messengers.
