Abstract Quantitative phase imaging (QPI) recovers the exact wavefront of light from intensity measurements. Topographical and optical density maps of translucent microscopic bodies can be extracted from these quantified phase shifts. We demonstrate quantitative phase imaging at the tip of a coherent fiber bundle using chromatic aberrations inherent in a silicon nitride hyperboloid metalens. Our…

Abstract This Perspective surveys the critical computational challenges associated with in vitro DNA-based data storage. As digital data expand exponentially, traditional storage media are becoming less viable, making DNA a promising solution due to its density and durability. However, numerous obstacles remain, including error correction, data retrieval from large volumes of noisy reads, and scalability.…

Credit: Alamy The months following the birth of Colleen Sullivan’s first child, a son, in 2014 were rough. Sullivan, a developmental psychologist at Worcester State University in Worcester, Massachusetts, was back teaching just three weeks after an emergency caesarean section, pumping breast milk between classes and coming home, exhausted, to her newborn in the evenings.…

From repealing climate policies to overturning guidance on the safe development of artificial intelligence (AI), Republican Donald Trump made plenty of promises during his presidential campaign that could affect scientists and science policy. But fulfilling all of his pledges won’t be easy. The US is the world’s science superpower — but for how long? Trump,…

Cognitive tests would be used less often to diagnose Alzheimer’s disease under a proposal by some scientists.Credit: Burger/Phanie/Science Photo Library Controversy has erupted among researchers over an effort to adopt blood tests and brain scans for diagnosing Alzheimer’s disease, rather than the cognitive screening that has been used for decades. Proponents of the change say…

Abstract Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and…

Scientists on Wednesday said that they have successfully stirred a strange matter called a “supersolid” – which is both rigid and fluid – for the first time, providing direct proof of the dual nature of this quantum oddity. In everyday life, there are four states of matter – solid, liquid, gas, and the rarer plasma.…

Abstract The event detection technique has been introduced to light-field microscopy, boosting its imaging speed in orders of magnitude with simultaneous axial resolution enhancement in scattering medium. As lift science has rapidly developed in the last decades, the demand for novel optical instruments is becoming increasingly urgent, helping discover new biomedical phenomena and mechanisms with…

Experiments with mice have revealed the neuroscience of why dogs shake their wet fur.Credit: Nat NT/Getty When a dog shakes water off its fur, the action is not just a random flurry of movements — nor a deliberate effort to drench anyone standing nearby. This instinctive reflex is shared by many furry mammals including mice,…
