Credit: Unsplash/CC0 Public Domain A new analysis of fossils believed to be juveniles of T. rex now shows they were adults of a small tyrannosaur, with narrower jaws, longer legs, and bigger arms than T. rex. The species, Nanotyrannus lancensis, was first named decades ago but later reinterpreted as a young T. rex. The first … Read more
Electrocatalysis enables facile organic halide activation. a, Selective reductive activation of organic halides over aldehydes and ketones is limited due to the similar reduction potentials accessed via OSET. b, Inner-sphere reductive activation of organic halides via molecular electrocatalysis or catalytic electrodes drives the reduction potential of organic halides to more positive potentials. c, This work … Read more
In addition to conventional secreted factors, cells also secrete ncRNA molecules (RNAkines). The molecular types of secreted factors are in bold, and representative examples or subfamilies, such as chemokines, are listed. The figure provides an overview of the diverse types of secreted factors contributing to intercellular signaling. Abbreviations: circRNA, circular RNA; lncRNA, long noncoding RNA; … Read more

Kennedy International Airport, New York (bottom right panel). The yellow, orange and red areas on these maps denote areas … Read more
Strategies on engineering the structure of MOFs for efficient photocatalysis were summarized in this review. Personal opinions on the opportunities and challenging as well as the developing trend of MOF-based photocatalysis were also addressed. Credit: Chinese Journal of Catalysis The ever-increasing global energy shortage and the worsening of the environment urgently require the substitution of … Read more

These findings are published in Socius, an open access journal. The research paper, coauthored by Brandon Andrew Robinson, associate professor and chair of the University of California, … Read more
TMTS light curve and Lomb–Scargle periodogram for J0526. Credit: arXiv (2023). DOI: 10.48550/arxiv.2312.13612 Using the Tsinghua University–Ma Huateng Telescopes for Survey (TMTS), an international team of astronomers has discovered a new binary known as TMTS J052610.43+593445.1. The newfound system is an ultrashort-orbital-period binary consisting of a subdwarf star and a white dwarf companion. The finding … Read more
People walk by a building collapsed following an earthquake in Shikamachi, Ishikawa prefecture, Japan Tuesday, Jan. 2, 2024. A series of powerful earthquakes in western Japan damaged homes, cars and boats, with officials warning people on Tuesday to stay away from their homes in some areas because of a continuing risk of major quakes and … Read more
Overview: Both mitochondrial and lysosomal stress stimulate TFEB nuclear translocation, followed by increased HKDC1 expression. HKDC1 stabilizes PINK1 through interaction with TOM70, thereby facilitating PINK1/Parkin-dependent mitophagy. Additionally, HKDC1 and the VDAC proteins with which it interacts are important for repair of damaged lysosomes and maintaining mitochondria–lysosome contact. HKDC1 prevents DNA damage–induced cellular senescence by maintaining … Read more
