High-Pressure Preparation of High-Strength Wood Materials
Gaoya wuli xuebaoMineral resources on Earth are finite, but wood is renewable. Therefore, replacing limited industrial materials with modified wood remains a long-term pursuit. This study processed samples of three wood types, including balsa (Ochroma lagopus), basswood (

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Host-guest strategy for full-visible-spectrum piezochromism in halogen-bonded organic frameworks
Nature CommunicationsFull-visible-spectrum piezochromism is vital for advanced anti-counterfeiting and storage device applications, yet remains challenging. Polycyclic aromatic hydrocarbons represent a promising class of piezochromic materials.

In situ high-pressure spectroscopic studies using moissanite (4H-SiC) anvils
AIP Advances, 2018 We examined the Raman scattering and IR absorption spectroscopy of 4H-SiC and its performance as an anvil material for high-pressure UV-visible absorption spectroscopic measurements.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Pressure-driven crystal symmetry and carrier concentration optimization for superior thermoelectric transport properties in layered AgCrSe2 [PDF]
Matter and Radiation at ExtremesPhase engineering has proven to be an effective strategy for achieving superior thermoelectric performance, while pressure is an excellent means of expanding the phase space of a material. In this paper, the effect of pressure-induced phase transition on

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Redox reactions in subducted CaCO3–Fe–SiO2 as a potential source of superdeep diamond inclusions
Scientific ReportsCaCO3 is one of the most abundant carbonates at the Earth’s surface. It is transported into the mantle in substantial quantities via subducted slabs and participates in the deep mantle carbon cycle along with other mantle materials.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
