For decades, the question seemed straightforward but defied a clean answer: how do cell-penetrating peptides (CPPs), short sequences of amino acids that can carry therapeutic payloads into cells, actually get through the plasma membrane? The answer matters enormously for drug delivery. CPPs are one of the most promising strategies for getting large, charged molecules (proteins, […]

As microelectronics continue to shrink and pack more power into each square millimeter, managing heat has become one of the defining engineering challenges of the decade. The hotspots in modern CPUs, 5G RF amplifiers, and laser diodes can exceed 40 W cm⁻² , enough to degrade performance, shorten lifetimes, and ultimately limit what the hardware […]

The Standard Model of particle physics is one of the most precisely tested frameworks in science, but it is not complete. It does not explain dark matter, dark energy, or why matter dominates over antimatter in the universe. One leading possibility is the existence of new particles, axions, Z’ bosons, dark photons, that mediate forces […]

A new species of walking shark has been described from the shallow waters of Milne Bay Province in southeastern Papua New Guinea, bringing the total number of known walking shark species to 10. The species, named Hemiscyllium dudgeonae (Dudgeon’s walking shark, or Dudgeon’s epaulette shark), was discovered during a night dive in March 2025 by […]

Green hydrogen, produced by splitting water with renewable electricity, is widely seen as essential for decarbonizing industries that cannot run directly on renewables: steel, cement, shipping, and aviation. Its adoption has been held back largely by cost. At current prices, green hydrogen runs roughly 6 to 8 euros per kilogram, compared with about 1.50 to […]

“If you build a data set and nobody can find it, is it useful?” asks a new Nature news feature published July 1. “Not as much as it could be.” The question is rhetorical but the stakes are not: with trust in science under sustained pressure from partisan actors and viral misinformation, the accessibility and […]

The boundary between chemistry and biology is becoming harder to draw. A team at the University of Minnesota led by biochemist Kate Adamala has built a cell from scratch, a system they call SpudCell, assembled entirely from purified chemical components, that can grow, replicate its genome, and divide. The preprint describing the work, rejected by […]

The replication crisis that has rattled psychology, economics, and biomedicine over the past decade may be a symptom of a deeper problem, argues a new Nature commentary by University of Chicago economist John A. List. The real issue is not whether findings replicate in the lab, it is whether they generalize to the settings where […]

India’s monsoon season has opened with its weakest performance in more than a decade. The country received just 99.5 millimeters of rainfall in June, 39.8 percent below the long-period average of 165.3 millimeters, making it the fifth-driest June since nationwide records began in 1901 and the driest since 2014. Only four Junes have been drier […]

The ATLAS collaboration at CERN’s Large Hadron Collider has reported an excess in top-antitop quark production with a statistical significance exceeding 8 sigma, far above the 5-sigma threshold conventionally required for discovery. The result, published in Reports on Progress in Physics, points to the formation of “toponium”: a fleeting, quasi-bound state in which the heaviest […]
