Island-dwelling mammal species often expand or contract in size, becoming giant or dwarf versions of their mainland counterparts. A new Science study from a global team shows that those giants and dwarfs have faced extreme risk of extinction -- an existential threat exacerbated by the arrival of humans.

In the first step toward understanding how dogs -- and perhaps humans -- might adapt to intense environmental pressures such as exposure to radiation, heavy metals, or toxic chemicals, researchers found that two groups of dogs living within the Chernobyl Exclusion Zone showed significant genetic differences between them. The results indicate that these are two distinct populations that rarely interbreed. While earlier studies focused on the effects of the Chernobyl Nuclear Power Plant disaster on various species of wildlife, this is the first investigation into the genetic structure of stray dogs living near the Chernobyl nuclear power plant.

Doublet Pool's regular thumping is more than just an interesting tourist attraction. A new study shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone's thumping thermometer.

Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.

Haptic holography promises to bring virtual reality to life, but a new study reveals a surprising physical obstacle that will need to be overcome.

The honeycomb patterns which are often found in salt deserts in Death Valley, US, and Bolivia, among other places, look like something from another world. Researchers can now explain the origin of the mysterious patterns.

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.

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.

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.

A recent excavation in Megiddo, Israel, unearthed the earliest example of a particular type of cranial surgery in the Ancient Near East -- and potentially one of the oldest examples of leprosy in the world.

Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite. It turns out that the marketing 'gag' of the 'Domaine du Météore' winery is acutally a real impact crater. Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again.

About 25 woolly sheep who seasonally -- for the past two years -- leave barns to nibble on lawns at various central campus locations, are doing much more than mowing, fertilizing and improving the ecosystem. The sheep also are improving people's mental health.

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.

Slipping and sliding on snowy or icy roads is dangerous. Salt and sand help melt ice or provide traction, but excessive use is bad for the environment. And sometimes, a surprise storm can blow through before these materials can be applied. Now, researchers ave filled microcapsules with a chloride-free salt mixture that's added into asphalt before roads are paved, providing long-term snow melting capabilities in a real-world test.

Baby kangaroo feces might help provide an unlikely solution to the environmental problem of cow-produced methane. A microbial culture developed from the kangaroo feces inhibited methane production in a cow stomach simulator. After researchers added the baby kangaroo culture and a known methane inhibitor to the simulated stomach, it produced acetic acid instead of methane. Unlike methane, which cattle discard as flatulence, acetic acid has benefits for cows as it aids muscle growth.

What role could rifted margins play in the transition to a carbon-neutral economy? Researchers summarize the current state of knowledge about the so-called rifting of continents. Rifting is the term researchers use to describe the process by which continental plates break and new oceans are formed.

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.
