It was the height of summer 2022 when the calls started coming in. Scores of dead deer suddenly littered rural properties and park preserves, alarming the public and inconveniencing landowners. According to officials at the Urbana Park District, it was Epizootic Hemorrhagic Disease (EHD), a midge-borne viral illness that pops up in white-tailed deer populations around the state every few years. And when susceptible deer are infected, they die within days. Now, scientists have found gene variants in deer associated with the animals' susceptibility to EHD.

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 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 redox regulation mechanism responsible for efficient production of ATP under varying light conditions in photosynthetic organisms has now been unveiled. Researchers investigated the enzyme responsible for this mechanism and uncovered how the amino acid sequences present in the enzyme regulate ATP production. Their findings provide valuable insights into the process of photosynthesis and the ability to adapt to changing metabolic conditions.

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.

Scientists have published the first record of a noble false widow spider feeding on a pygmy shrew, a species of tiny mammal protected in Ireland. The pygmy shrew -- a protected mammal -- was captured on spider's web on a bedroom window, then paralyzed and hoisted to its doom by the invasive spider.

Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales who prey on them. Fraser River Chinook salmon that come later in the season have lower energy density.

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.

Groups of spiders could be used as an environmentally-friendly way to protect crops against agricultural pests. That's according to new research which suggests that web-building groups of spiders can eat a devastating pest moth of commercially important crops like tomato and potato worldwide.

Psychologists had people learn words from two phonetically similar languages in virtual reality environments. Those who learned each language in its own unique context mixed up fewer words and were able to recall 92% of the words they had learned. In contrast, participants who had learned both sets of words in the same VR context were more likely to confuse terms between the two languages and retained only 76% of the words. Regardless of group, those participants who felt immersed in the VR world remembered more than those who did not feel immersed.

Enhancing the virtual experience with the touch sensation has become a hot topic, but today's haptic devices remain typically bulky and tangled with wires. Researchers have now developed an advanced wireless haptic interface system, called WeTac, worn on the hand, which has soft, ultrathin soft features, and collects personalized tactile sensation data to provide a vivid touch experience in the metaverse.

By breaking the laws of physics in a virtual reality environment, researchers find that changing the location of a virtual assistant's voice in specific ways can be used as a tool to build rapport with customers.

Gait analysis systems measure certain metrics to give their results. These results then drive clinical treatment for gait correction. However, detailed gait analysis requires expensive equipment, and a lot of space, markers, time. Measurements from markerless, video-based gait analysis systems, on the other hand, are inaccurate. To improve upon existing systems, researchers have now combined RGB camera-based pose estimation and an inertial measurement unit sensor for gait analysis. This significantly reduces errors in the process.
