Evolving Dark Energy or Supernovae Systematics?

Kavli Affiliate: George Efstathiou | Summary:Recent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with DESI measurements of baryon acoustic oscillations (BAO) and observations of the cosmic microwave background (CMB) […]

Spontaneous calcium transients in hair cell stereocilia

Kavli Affiliate: Dwight Bergles | Authors: Saman Hussain, Miloslav Sedlacek, Runjia Cui, Wendy Zhang-Hooks, Dwight E Bergles, Jung-Bum Shin, Katie Kindt and Bechara Kachar | Summary: The hair bundle of auditory and vestibular hair cells converts mechanical stimuli into electrical signals through mechanoelectrical transduction (MET). The MET apparatus is built around a tip link that […]

Quantifying Bursty Star Formation in Dwarf Galaxies

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yuan-Sen Ting, Alexander P. Ji, , , | Summary: Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than $sim$100 Myr should lead to discontinuous tracks in […]

Insights, opportunities and challenges provided by large cell atlases

Kavli Affiliate: Iwijn De Vlaminck | Summary:The field of single-cell biology is growing rapidly and is generating large amounts of data from a variety of species, disease conditions, tissues, and organs. Coordinated efforts such as CZI CELLxGENE, HuBMAP, Broad Institute Single Cell Portal, and DISCO, allow researchers to access large volumes of curated datasets. Although […]
