Italian in the no-man's land between stress-timing and syllable-timing? speakers are more stress-timed than listeners [PDF]
Interspeech 2011, 2011 How syllable-timed is Italian? We investigate two contexts for vowel reduction, unstressed syllables and syllables in polysyllabic words. In a production experiment, a large sample of speakers from Tuscany read di- and trisyllabic target words with different stress placement in a sentence context. Results showed vowel reduction in unstressed syllables,

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Stress-timed: word-based? Testing a hypothesis in prosodic typology [PDF]
, 2017 In recent research on cross-linguistic differences in linguistic rhythm, it has been hypothesized that the traditional dichotomy ‘stress-timed' versus ‘syllable-timed' might be recast with respect to which level of the Prosodic Hierarchy constitutes the ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Language discrimination by newborns: Teasing apart phonotactic, rhythmic, and intonational cues [PDF]
, 2002 Speech rhythm has long been claimed to be a useful bootstrapping cue in the very first steps of language acquisition. Previous studies have suggested that newborn infants do categorize varieties of speech rhythm, as demonstrated by their ability to ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Acoustic correlates of linguistic rhythm: Perspectives [PDF]
, 2002 The empirical grounding of a typology of languages' rhythm is again a hot issue. The currently popular approach is based on the durations of vocalic and intervocalic intervals and their variability. Despite some successes, many questions remain. The main

Stress-timing in Brazilian Portuguese
Journal of Phonetics, 1981 Abstract: This paper presents instrumental and phonological evidence that Brazilian Portuguese has a tendency toward stress-timing: (1) inter-stress durations are not directly proportional to the number of syllables; (2) many differences in interstress durations are not perceptible; (3) syllable duration is inversely proportional to the number of ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...
