From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

A Possible Periodic Rotation Measure Evolution in the Repeating FRB 20220529
The Astrophysical Journal LettersFast radio bursts (FRBs) are mysterious millisecond-duration radio transients of extragalactic origin. Some of them repeat, while others apparently do not.

An insight into the extragalactic transient and variable microJy radio sky across multiple decades [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The mJy variable extragalactic radio sky is known to be broadly non-changing with approximately $3{{\ \rm per\ cent}}$ of persistent radio sources exhibiting variability that is largely active galactic nucleus-related (AGN). In the faint (

A search for radio pulsars in globular clusters, supernova remnants and transient X-ray sources [PDF]
Monthly Notices of the Royal Astronomical Society, 1996 We present the results of a targeted search for radio pulsars in globular clusters, supernova remnants (SNRs) and transient X-ray sources. 85 globular clusters, 29 SNRs and three transient X-ray sources were observed in the course of the search, during which four pulsars were found. For each object searched, the sensitivity limit is given. The four new

‘Guide and Prejudice’— How Argonautes recognize targets across domains of life
FEBS Letters, EarlyView.Argonaute proteins use short nucleic‐acid guides to locate and regulate specific targets across all domains of life. Despite striking diversity—from human gene silencing to bacterial immune defence—all Argonautes share a conserved three‐stage recognition logic: guide‐directed sampling, progressive target pairing with a conformational checkpoint and ...

Multiwavelength Observations of the Apparently Nonrepeating FRB 20250316A
The Astrophysical JournalThe physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations have been widely conducted, only Galactic FRB 20200428D is associated with an X-ray burst from the magnetar SGR J1935+2154.

Decentralized Searching of Multiple Unknown and Transient Radio Sources with Paired Robots
Engineering, 2015 ABSTRACTIn this paper, we develop a decentralized algorithm to coordinate a group of mobile robots to search for unknown and transient radio sources. In addition to limited mobility and ranges of communication and sensing, the robot team has to deal with challenges from signal source anonymity, short transmission duration, and variable transmission ...
