January 2025

Institute for Particle Physics Phenomenology, Department of Physics, Durham University, Durham, DH1 3LE UK.

Extended dark matter objects (EDOs) are popular dark matter candidates that interact gravitationally with the Standard Model. These gravitational interactions can be used to constrain their allowed parameter space. However, EDOs can have different formation mechanisms, sizes, and shapes, requiring a case-by-case analysis when studying their impact on different areas of cosmology.

Background: Up to 23% of breast cancer patients recurred within a decade after trastuzumab treatment. Conversely, one trial found that patients with low HER2 expression and metastatic breast cancer had a positive response to trastuzumab-deruxtecan (T-Dxd). This indicates that relying solely on HER2 as a single diagnostic marker to predict the efficacy of anti-HER2 drugs is insufficient.

Charge-transfer complexation of coordination cages for enhanced photochromism and photocatalysis.

Nat Commun

January 2025

State Key Laboratory of Petroleum Molecular & Process Engineering, Shanghai Key Laboratory of Green Chemistry and Chemical Processes, School of Chemistry and Molecular Engineering, East China Normal University, Shanghai, China.

Intensified host-guest electronic interplay within stable metal-organic cages (MOCs) presents great opportunities for applications in stimuli response and photocatalysis. Zr-MOCs represent a type of robust discrete hosts for such a design, but their host-guest chemistry in solution is hampered by the limited solubility. Here, by using pyridinium-derived cationic ligands with tetrakis(3,5-bis(trifluoromethyl)phenyl)borate (BAr) as solubilizing counteranions, we report the preparation of soluble Zr-MOCs of different shapes (1-4) that are otherwise inaccessible through a conventional method.

Formation of I+III supercomplex rescues respiratory chain defects.

Cell Metab

January 2025

Cardiovascular and Metabolic Diseases, Duke-NUS Medical School, Singapore, Singapore. Electronic address:

Mitochondrial electron transport chain (ETC) complexes partition between free complexes and quaternary assemblies known as supercomplexes (SCs). However, the physiological requirement for SCs and the mechanisms regulating their formation remain controversial. Here, we show that genetic perturbations in mammalian ETC complex III (CIII) biogenesis stimulate the formation of a specialized extra-large SC (SC-XL) with a structure of I+III, resolved at 3.

Department of Obstetrics and Gynecology, Spencer Fox Eccles School of Medicine, University of Utah Health, Salt Lake City, Utah; the Department of Obstetrics and Gynecology, Warren Alpert Medical School at Brown University, and Women and Infants Hospital of Rhode Island, Providence, Rhode Island; the National Academies of Sciences, Engineering, and Medicine, and Baker Donelson, Washington, DC; KFF, San Francisco, California; and the Department of Obstetrics and Gynecology, Duke Cancer Institute, Duke School of Medicine, Durham, North Carolina. All authors served on the National Academies Committee as committee members or employees of the National Academies.

Despite efforts to address inequities, research on women's health conditions (defined as those that uniquely or differently affect women and female individuals) remain significantly understudied. As directed by Congress, the National Institutes of Health (NIH) Office of Research on Women's Health requested the National Academies of Sciences, Engineering, and Medicine (National Academies) to conduct an assessment of the state of women's health research at the NIH. The findings of the National Academies committee include: 1) a significant funding inequity, with less than 8% of the total NIH grant budget for fiscal year 2023 allocated to women's health research; 2) a need for improved strategic NIH-wide priority setting, oversight, and adherence to existing policies to support women's health research; 3) a need for a specific institute for research on conditions specific to women's health; and 4) a need for sufficient training and additional funding to grow and retain the women's health research workforce.
