A giant insect found in Arkansas has set historic records. The Polystoechotes punctata or giant lacewing is the first of its kind recorded in eastern North America in over 50 years. The giant lacewing was formerly widespread across North America, but was mysteriously extirpated from eastern North America by the 1950s. This discovery suggests there may be relic populations of this large insect yet to be discovered.

The sustained loss of a once abundant species of sea urchin in the Caribbean could also result in the functional extinction of diverse coral species from the region's reefs, according to new research.

Researchers developed an augmented reality headset called X-AR that combines computer vision and wireless perception to find hidden objects in a room and then guide the wearer to retrieve the targeted item.

Dinosaur claws had many functions, but now a team has shown some predatory dinosaurs used their claws for digging or even for display.

Amphibians worldwide are affected by climate change and potentially one of the most threatened. Biologists found that some species of amphibians are more likely to be sensitive to climate change because they are not protected by state or federal regulations. The team determined that approximately 11 percent of anuran species are sensitive to climate change, but are not currently listed as at-risk either at the state, federal, or international levels.

After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.

By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.

Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.

The meat-eating dinosaurs known as theropods that roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly different dinosaur sizes evolved recently found -- to their surprise -- that smaller and larger theropod dinosaurs like these didn't necessarily get that way merely by growing slower or faster.

The endangered Saimaa ringed seal is an Ice Age relict living in the highly labyrinthine Lake Saimaa, Finland. The newly published work shows that although individual seals have greatly reduced genetic variation, the loss of variation has been complementary, preserving the adaptive potential of the whole population.

Sensing a hug from each other via the internet may be a possibility in the near future. A research team recently developed a wireless, soft e-skin that can both detect and deliver the sense of touch, and form a touch network allowing one-to-multiuser interaction. It offers great potential for enhancing the immersion of distance touch communication.

Biologists use current and historical bird surveys to reveal how land use change has amplified -- and in some cases mitigated -- the impacts of climate change on bird populations in Los Angeles and the Central Valley over the past century. The study found that urbanization and much hotter and drier conditions in L.A. have driven declines in more than one-third of bird species in the region.

Researchers have provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America's Pacific Coast by preying on substantial numbers of kelp-eating urchins.

Researchers have demonstrated a new hands-free approach to convey realistic haptic feedback in virtual reality (VR). Their 'multisensory pseudo-haptics' uses a combination of headset visuals and tactile feedback from a wrist bracelet to convey sensations of touch.

Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.

The metaverse is a technological revolution in the field of virtual reality, with potential benefits to public health research. A new article proposes several new ways in which the metaverse can help us design, test, and experience health-promoting environments to minimize the risk of non-communicable diseases.

New research shows that the feathers of seabirds such as the Wandering Albatross can provide clues about their long-distance foraging, which could help protect these species from further decline.

Most land-based mammals in the Brazilian Amazon are threatened by climate change and the savannization of the region.

Scientists found that some reefs in the tropical Pacific Ocean could maintain high coral cover into the second half of this century by shuffling the symbiotic algae they host. The findings offer a ray of hope in an often-dire picture of the future of coral reefs worldwide.

Researchers are using emerging technology to demonstrate a process that will enable more immersive and realistic virtual and augmented reality displays with the world's smallest and thinnest micro-LEDs.
