No vertebrate (fish, mammal, bird, reptile, or amphibian) has ever had an odd number of limbs. Despite this "forbidden phenotype," some animals seem to use other body parts as a third or fifth "limb" to move from one place to another.

Mexican naval vessels, spotter planes and conservationists are patrolling the upper Gulf of California in a race against time to save the world's rarest marine mammal from extinction.

Making use of the LAMOST spectra data as the training sample, a research team led by Dr. Wang Shoucheng and Prof. Ma Jun from National Astronomical Observatories of Chinese Academy of Sciences (NAOC) proposed a new method to search for star clusters in the Andromeda galaxy.

Newly discovered species are at a higher risk of extinction than those first described long ago, according to a new study involving researchers at The Australian National University (ANU).

In findings that could help advance another "viable pathway" to fusion energy, research led by Lawrence Livermore National Laboratory (LLNL) physicists has proven the existence of neutrons produced through thermonuclear reactions from a sheared-flow stabilized Z-pinch device.

Quantum theory was originally formulated using complex numbers. Nonetheless, when replying to a letter by Hendrik Lorenz, Erwin Schrödinger (one of its founding fathers), wrote: "Using complex numbers in quantum theory is unpleasant and should be objected to. The wave function is surely fundamentally a real function."

What happens if you reintroduce wolves into certain areas? Or if bats become ill, and their population declines? How does climate change affect a particular species—and what does that mean for human well-being?

The giant panda feeds exclusively on fibrous bamboo, yet they still manage to stay chubby and healthy. In a study published January 18 in the journal Cell Reports, researchers reveal that shifts in the bear's gut microbiota in the season when nutritious bamboo shoots become available helps the herbivorous bear gain more weight and store more fat, which may compensate for the lack of nutrients in seasons when there are only bamboo leaves to chew on.

Twin panda cubs made their first public appearance Wednesday before devoted fans in Tokyo, but they will be on display only briefly for now—over three days—due to a spike in COVID-19 cases driven by the omicron variant.

The sweetness of sugar is one of life's great pleasures. People's love for sweet is so visceral, food companies lure consumers to their products by adding sugar to almost everything they make: yogurt, ketchup, fruit snacks, breakfast cereals and even supposed health foods like granola bars.
