Microheterogeneous singlet oxygen generation at air–water interfaces

Singlet oxygen (1 O 2) drives key photochemical reactions in the atmosphere and natural waters, yet its spatial distribution in multiphase systems remains unexplored. Here, we reveal strong microscale ...

Rational quantum mechanics: Testing quantum theory with quantum computers

Is there a fundamental reason why quantum computers cannot factor large integers used for encryption today? We introduce a theory of quantum physics based on the notion that the continuum nature of ...

The m5C orchestrator NSUN7 drives SPARC/HMGB1 axis–mediated inflammation to exacerbate kidney injury

RNA modifications like 5-methylcytosine (m5C) are emerging as critical regulators of inflammation, but their functional role in kidney diseases remains unknown. We identify NOP2/Sun RNA ...

Correction for Goyette et al., Targeting Axl favors an antitumorigenic microenvironment that enhances immunotherapy responses by decreasing Hif-1α levels

In addition, the authors note that in Fig. 5A, the Vimentin and Tubulin immunoblots were generated from lysates run on two parallel gels rather than from a single membrane. Equal amounts of the same ...

Calsyntenin-3 suppresses inflammation via inhibition of TLR N-glycosylation and membrane localization

Uncontrolled inflammation underlies many diseases. Here, we identify calsyntenin-3 (CLSTN3) as an endogenous brake on TLR-triggered inflammation via impairing the N-glycosylation and membrane ...
