Constraints on the Star-Forming Interstellar Medium in Galaxies Back to the First Billion Years of Cosmic Time [PDF]

open access: yes, 2011
Constraints on the molecular gas content of galaxies at high redshift are crucial to further our understanding of star formation and galaxy evolution through cosmic times, as molecular gas is the fuel for star formation.

New mechanism for non-trivial intra-molecular vibrational dynamics

open access: yes, 2009
We investigate the time evolution process of one selected (initially prepared by optical pumping) vibrational molecular state, coupled to all other intra-molecular vibrational states of the same molecule, and also to its environment.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Gene expression atlas of the Colorado potato beetle (Leptinotarsa decemlineata)

open access: yesScientific Data
The Colorado potato beetle (CPB) is a major pest of potato crops, known for its remarkable ability to develop resistance to more than 50 pesticides. For decades, CPB has served as a model species for studying insecticide resistance, insect physiology ...

Molecular Biology and Evolution of Cancer: From Discovery to Action

open access: yesMolecular biology and evolution, 2019
Cancer progression is an evolutionary process. During this process, evolving cancer cell populations encounter restrictive ecological niches within the body, such as the primary tumor, circulatory system, and diverse metastatic sites.

Why emerging leaders should focus on being good postdoctoral supervisors

open access: yesFEBS Letters, EarlyView.
Swamped with work and suddenly a new student is waiting at your doorstep for supervision? Great—this is your chance! In this article, we share tips on how postdocs can strengthen their leadership skills while supervising students. This image has been created using DALL·E. Many postdocs work as leaders later in their career.

Mechanisms of molecular evolution

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Both drift and selection are important for nucleotide substitutions in evolution. The nearly neutral theory was developed to clarify the effects of these processes. In this article, the nearly neutral theory is presented with special reference to the nature of weak selection.

The molecular evolution of acquired resistance to targeted EGFR blockade in colorectal cancers

open access: yesNature, 2012
Colorectal tumours that are wild type for KRAS are often sensitive to EGFR blockade, but almost always develop resistance within several months of initiating therapy.

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.
