Hawai’i is home to a broad, beautiful array of bird species found only on its islands — like the stunningly diverse honeycreepers, many on the border of extinction. Now, a local team is removing invasive predators, restoring habitats, and battling mosquito-borne diseases to protect honeycreepers from their latest threat: avian malaria.

Abstract Complex field imaging, which captures both the amplitude and phase information of input optical fields or objects, can offer rich structural insights into samples, such as their absorption and refractive index distributions. However, conventional image sensors are intensity-based and inherently lack the capability to directly measure the phase distribution of a field. This limitation…

Freeman Hrabowski is the first of Nature’s Changemakers.Credit: Marvin Joseph/The Washington Post/Getty In October 2022, Nature published a special issue on the urgent need to tackle racism in science (see go.nature.com/3uxidgb). The journal has returned to the topic repeatedly in response to racism’s continuing and pervasive effect on many scientists’ working lives. This week sees…

Abstract Harnessing the potential of considerable food security efforts requires the ability to translate them into commercial applications. This is particularly true for alternative protein sources and startups being on the forefront of innovation represent the latest advancements in this field. Introduction In 2022 almost 735 million people, 9.2% of the global population, were undernourished1…

Educators with Bradenton’s Bishop Museum of Science and Nature say such a tusk could be anywhere from 10,000 to millions of years old. VENICE, Fla. — A Tampa man made an incredible discovery while diving off the coast of Venice last month. While sifting through the sand, Alex Lundberg found a 4-foot mastodon tusk.  “This…

Whales along the West Coast have been having a tough couple of years. Humpback whales in particular are getting entangled in fishing lines more often than usual, leading to injuries and deaths. It also costs fishing fleets money, time and equipment. No one wants whales caught in lines meant for fish. So OSU’s Geospatial Ecology…

Editor’s note: This article was originally published on November 4, 2022. It has since been updated. In 2012, scientists discovered a remarkable underground ant city that had once been home to millions of insects, as shown in the documentary “Ants: Nature’s Secret Power.” This intricate network of roadways, pathways, and gardens was unearthed in Brazil,…

We present a method to alleviate re-identification risks behind sharing haplotype reference panels for imputation. In an anonymized reference panel, one might try to infer the genomes’ phenotypes to re-identify their owner. Our method protects against such attack by shuffling the reference panels genomes while maintaining imputation accuracy. This is a preview of subscription content,…
