Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates
Advanced Science, EarlyView.Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

The White Dwarf in EM Cygni: Beyond The Veil
, 2009 We present a spectral analysis of the FUSE spectra of EM Cygni, a Z Cam DN system. The FUSE spectrum, obtained in quiescence, consists of 4 individual exposures (orbits): two exposures, at orbital phases phi ~ 0.65 and phi ~ 0.90, have a lower flux; and ...

The Mass of the White Dwarf Companion in the Self-Lensing Binary KOI-3278: Einstein vs. Newton [PDF]
, 2019 KOI-3278 is a self-lensing stellar binary consisting of a white-dwarf secondary orbiting a Sun-like primary star. Kruse and Agol (2014) noticed small periodic brightenings every 88.18 days in the Kepler photometry and interpreted these as the result of ...

Testing the white dwarf mass-radius relationship with eclipsing binaries [PDF]
, 2017 We present high-precision, model-independent, mass and radius measurements for 16 white dwarfs in detached eclipsing binaries and combine these with previously published data to test the theoretical white dwarf mass–radius relationship.

Unraveling Alkali Ion Electron Donation for Enhancing Heterogeneous Catalytic Oxidation
Advanced Science, EarlyView.A new mechanistic pathway for potassium (K) ions as electron donors is identified by constructing single K ion chains confined within hexagonal WO3 tunnels. The as‐produced high‐electron‐density Kδ+ (0<δ<1) ions not only facilitate the formation of oxygen vacancies that behave classical electronic effect but, more importantly, also directly donate ...

, 2012 There is a striking and unexplained dearth of brown dwarf companions in close orbits (< 3AU) around stars more massive than the Sun, in stark contrast to the frequency of stellar and planetary companions.

Unstable low-mass planetary systems as drivers of white dwarf pollution [PDF]
, 2017 At least 25 percent of white dwarfs show atmospheric pollution by metals, sometimes accompanied by detectable circumstellar dust/gas discs or (in the case of WD 1145+017) transiting disintegrating asteroids.

An unusual white dwarf star may be a surviving remnant of a subluminous Type Ia supernova [PDF]
Science, 2017 Unusual star may be supernova debris Type Ia supernovae occur when a white dwarf star is completely destroyed in a thermonuclear explosion. Recently, another class of supernova has been found, dubbed type Iax; these look like type Ia but are much fainter

Advanced Science, EarlyView.Multicomponent alloys, such as high‐entropy alloys (HEAs), are considered to be in a random solid solution. However, recent studies have shown that short‐range ordering (SRO) is prevalent in these HEAs due to multipairwise interactions among the constituent elements, which can be deleterious.
