Ferroptosis, a form of cell death driven by excessive lipid peroxidation, is induced by inhibiting GPX4, a key regulator of ferroptosis. Wang et al. reported that MALT1 protease activity regulates ...

The United States produces 41% of the world's corn and 38% of the world's soybeans. These crops comprise two of the four largest sources of caloric energy produced and are thus critical for world food ...

A Science Strategy for Human Exploration of Mars (1), charts a bold, scientifically based blueprint for humanity’s greatest cosmic adventure—sending explorers to Mars to answer the universe’s most ...

Future drought is projected to occur under warmer temperature conditions as climate change progresses, referred to here as global-change-type drought, yet quantitative assessments of the triggers and ...

In one of the most famous classic papers in the annals of science, Edwin Hubble’s 1929 PNAS article on the observed relation between distance and recession velocity of galaxies—the Hubble Law—unveiled ...

Many swimming and flying animals are observed to cruise in a narrow range of Strouhal numbers, where the Strouhal number S t = 2 f A / U is a dimensionless parameter that relates stroke frequency f, ...

The Democracy Index finding holds up best. Its negative direct effect on offensive VEI (we use β for SDM coefficients throughout) survives spatial adjustment in every bivariate specification (Table 1) ...

Assembling the mitochondrial ATP synthase The assembly of the mitochondrial ATP synthase is a complicated process that involves the coordinated association of mitochondrially and nuclear encoded ...

For practical purposes, utilizing high thermal conductivity materials (HTCMs) to implement regeneration is a promising alternative to attempts of pursuing an ideal thermal diode, while they still ...
