Some animal species can survive successfully without sexual reproduction
In the framework of an international research project, a team of scientists have demonstrated for the first time that asexual reproduction can be successful in the long term. The animal they studied is the beetle mite Oppiella nova. Until now, the su.....»»
Only 3% of South Africans can name all five national animals and plants. Why these symbols matter
Alongside a national flag, anthem and coat of arms, most countries have one or more plant and animal species that they designate as national symbols. The national animal of China, for example, is the giant panda, a nation-wide source of pride and dip.....»»
A physicist and his cat "reveal" the equation of cat motion
In the social media age, there is little doubt about who is the star of the animal kingdom. Cats rule the screens just as their cousins, the lions, rule the savanna. Thanks to Erwin Schrödinger, this feline also has a place of honor in the history o.....»»
Experiments find coral reefs can survive some climate change—with help
If carbon emissions are curbed and local stressors are addressed, coral reefs have the potential to persist and adapt over time. That's according to a study published in the Proceedings of the National Academy of Sciences by researchers at the Univer.....»»

Fossil of huge terror bird offers new information about wildlife in South America 12 million years ago
Researchers including a Johns Hopkins University evolutionary biologist report they have analyzed a fossil of an extinct giant meat-eating bird—which they say could be the largest known member of its kind—providing new information about animal li.....»»
Not too big, not too small: Why modern humans are the ideal size for speed
The fastest animal on land is the cheetah, capable of reaching top speeds of 104 kilometers per hour. In the water, the fastest animals are yellowfin tuna and wahoo, which can reach speeds of 75 and 77 km per hour respectively. In the air, the title.....»»
Bats use echolocation to make mental maps for navigation
Despite only working over short distances, echolocation is enough to get bats home. Many species of bats use echolocation to avoid obstacles like tree branches and hunt small inse.....»»
"Wing spreading" adaptation in fruit flies offers insights into female courtship behavior
In the game of evolution, key behavioral adaptations that confer fitness in survival and reproduction, paying tremendous dividends for an individual's progeny, may seemingly arise from thin air—so much so, even familiar species like the humble frui.....»»
New insights into mango evolution: Study reveals extensive hybridization within the Mangifera genus
A research team investigated whole chloroplast genomes and nuclear gene sequences from 14 species, uncovering new insights into the genetic diversity and hybrid origins of mango species. They used the evolutionary relationships within the Mangifera g.....»»
New method successfully recycles carbon fiber composite into reusable materials
USC researchers have developed a new process to upcycle the composite materials appearing in automobile panels and light rail vehicles, addressing a current environmental challenge in the transportation and energy sectors. The study recently appeared.....»»

How researchers can maximize biological insights using animal-tracking devices
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell a deeper story about the lives of.....»»
Nanofibrils study successfully measures strength of spider web "super fibers"
How small is "small?" Spider silk nanofibrils are just a few molecular layers thick, equivalent to approximately one ten-thousandth the diameter of a human hair. They're invisible to the naked eye and cannot be seen under an ordinary microscope......»»
