Golden Orb on Alaska Seafloor Is a Rare Deep-Sea Anemone’s Cuticle

A golden orb found on the Gulf of Alaska seafloor is not an alien object but the detached gold cuticle of Relicanthus daphneae, a rare deep-sea anemone. DNA sequencing showed a 99.9% match to the species, and researchers explain that the anemone sheds this golden layer as it moves, which can sink and resemble something from another world. The finding clarifies the organism’s identity and underscores how much deep-sea biodiversity remains poorly understood.

Beavers as urban flood engineers reshape London's wetlands

Beavers reintroduced to West London in 2023 dammed a creek to create wetlands that absorb heavy rainfall, reducing flooding at Greenford Tube and boosting urban biodiversity; part of Britain’s broader beaver reintroduction effort to restore wetlands and adapt to a wetter climate, a trend that also meets some farmer concerns over land and water management, with licensing and relocation helping manage conflicts.

Ocean Census Sees Record 1,121 New Marine Species in One Year

The Nippon Foundation-Nekton Ocean Census reports 1,121 newly identified marine species in a single year—a 54% rise—built from 13 expeditions and nine discovery workshops, including corals, crabs, shrimps, sea urchins, anemones, a 'Ghost Shark' chimaera and a Mediterranean shrimp. The findings underscore vast undiscovered ocean biodiversity and the urgency of cataloging species before extinction, noting that up to 90% of ocean life remains undiscovered and averaging 13.5 years between discovery and formal description.

Online Tool Rewinds Earth's Map to 320 Million Years Ago

Researchers at Utrecht University have built Paleolatitude.org, an online platform that lets you enter any modern location and see its estimated latitude at different times up to 320 million years ago, using refined tectonic reconstructions, magnetic rock data, and dating techniques to map continental movement—and including smaller plates and lost landmasses. The tool supports studies of past climates, fossils, biodiversity, and mass extinctions, with plans to extend back further in time.

Postwar monocultures fuel Japan's pollen crisis

Japan's spring allergies are blamed on postwar monocultures of sugi and hinoki, whose heavy pollen blankets cities each spring; the government aims to cut 20% of these plantations and replace them with biodiverse broadleaf forests, while using pollen forecasting and new treatments, though the transition faces soil erosion, biodiversity loss, and climate-change challenges.

Ocean Census Discovers 1,121 New Ocean Species, From Glass-Walled Worms to Ghost Sharks

The Ocean Census reports 1,121 previously unknown ocean species discovered since last April, highlighting deep-sea biodiversity through findings such as a glass-shelled worm living in a glass sponge off Japan, ghost sharks, unknown rays and catsharks, ping-pong ball sponges, and sea pens. However, many of these discoveries have not yet been formally described as new species, a process that can take years, underscoring how much we still don't know about Earth's biodiversity.

Sentosa Waters Reveal a New Chironex Box Jellyfish and a Thai Range Expansion

Researchers from Tohoku University and the National University of Singapore identified a new box jellyfish, Chironex blakangmati, off Sentosa Island, Singapore, distinguishing it from related species by distinct perradial lappet morphology and confirming it with genetic analysis, expanding the Chironex genus to four species. In the same expedition, samples of C. indrasaksajiae—previously associated with Thai waters—were found in Singapore for the first time, indicating a surprising range expansion. The study highlights Southeast Asia’s jellyfish biodiversity and public-safety implications and was published in the Raffles Bulletin of Zoology.

World Sand Crisis: Extraction Outpaces Replenishment, Endangering Coasts and Ecosystems

A UN report warns that global demand for sand—vital for construction, infrastructure and coastal protection—outpaces its natural replenishment, risking livelihoods, fisheries and ecosystems as large-scale land reclamation (notably in the Maldives) destroys reefs and protected habitats; the analysis urges better governance, data, and transparency to manage sand use amid rising sea levels.

WA’s Deep-Sea Canyons Reveal Hidden Life, Including Giant Squid

A Curtin University–led expedition used environmental DNA to survey WA’s deep-sea canyons off the Ningaloo coast, collecting over 1,000 water samples from depths up to 4,510 meters and uncovering a rich ecosystem that includes traces of giant squid along with 226 species across 11 groups—plus numerous potential new-to-science records—highlighting how much remains unknown about Australia’s deep ocean and the value of eDNA for biodiversity discovery and conservation planning.

April’s science images spotlight a detailed 3D map of the universe and other breakthroughs

April’s best science images span cosmic to terrestrial: the DESI project delivers the most detailed 3D map of the universe from 47 million galaxies and quasars, accompanied by Earth-bound highlights such as climate-threatened cherry blossoms in Japan, the discovery of a new endangered Liopholis mutawintji skink in Australia, a lab-grown dinosaur-collagen leather bag, insights into limb regeneration, advanced 3D imaging of coral skeletons with deep learning, and NASA’s Artemis II Moon fly-by with Space Launch System boosters.

Backyard Discovery Suggests Ants Disperse Oak Galls, Not Just Seeds

Penn State and SUNY researchers, sparked by an 8-year-old’s backyard observation, report that oak galls formed by gall wasps can be collected and carried by ants just like seeds. The study reveals a three-way interaction among ants, oaks, and wasps, with the kapéllo cap on galls releasing free fatty acids similar to seed elaiosomes, attracting ants to disperse the galls. This finding broadens our understanding of forest biodiversity and overlooked ecological interactions.

DNA traces reveal giant squid and hidden life in WA's deep-sea canyons

Australian researchers used environmental DNA from seawater to survey deep-sea canyons off Western Australia, revealing 226 species including the first WA-record of a giant squid via eDNA and indications of potentially new species, underscoring the value of non-invasive methods for mapping biodiversity in extreme depths and informing conservation as deep-sea ecosystems face climate change, fishing, and resource pressures.

Where Was Your Backyard 320 Million Years Ago? A New Tool Maps Earth's Drift

Paleolatitude.org now features a global 320-million-year paleogeographic model with updated paleomagnetic data, letting users trace any location’s latitude through continental drift, export results, and upload data for bulk paleolatitude calculations. Researchers illustrate its use by reconstructing late Jurassic biodiversity gradients and mapping a Dutch fossil site to ancient latitudes near today’s Arabia, with plans to extend the model back to the Cambrian to study biodiversity resilience through deep time.

Hong Kong pond yields a new 24-eyed box jellyfish

Researchers in Hong Kong’s Mai Po Nature Reserve describe Tripedalia maipoensis, a tiny box jellyfish about 0.6 inches long, as a new species—the fourth described in the Tripedaliidae family. DNA analysis shows it is distinct from Tripedalia cystophora (16S rRNA ~17.4% difference). The jellyfish has 24 eyes arranged in four rhopalia, with two lens eyes likely forming images to aid navigation under mangroves. Found during nocturnal sampling of shrimp ponds, this is the first box jellyfish formally reported from Chinese coastal waters and underscores hidden biodiversity in human-modified habitats. The study was published in Zoological Studies.
