What India needs to get through its covid crisis
In a cruel irony, India, the world's vaccine manufacturing powerhouse, is now crippled by a virus for which multiple safe and effective vaccines have been developed in record time. Official reports of more than 380,000 new cases and 3,400 deaths daily, while staggering, likely underestimate the actual toll. As health systems across India buckle under the pressure of a second wave of covid-19 infe

Rapid postglacial rebound amplifies global sea level rise following West Antarctic Ice Sheet collapse
Geodetic, seismic, and geological evidence indicates that West Antarctica is underlain by low-viscosity shallow mantle. Thus, as marine-based sectors of the West Antarctic Ice Sheet (WAIS) retreated during past interglacials, or will retreat in the future, exposed bedrock will rebound rapidly and flux meltwater out into the open ocean. Previous studies have suggested that this contribution to glo

Na+/Ca2+ exchanger mediates cold Ca2+ signaling conserved for temperature-compensated circadian rhythms
Circadian rhythms are based on biochemical oscillations generated by clock genes/proteins, which independently evolved in animals, fungi, plants, and cyanobacteria. Temperature compensation of the oscillation speed is a common feature of the circadian clocks, but the evolutionary-conserved mechanism has been unclear. Here, we show that Na + /Ca 2+ exchanger (NCX) mediates cold-responsive Ca 2+ si
