Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR). Each is only known from a single specimen discovered in 1981 and 2013, respectively.
Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these "micro-bristle-bots" might work together to sense environmental changes, move materials - or perhaps one day repair injuries inside the human body.
The culprit responsible for the decline of Mexico's once-lucrative jumbo squid fishery has remained a mystery, until now. A new Stanford-led study published in the ICES Journal of Marine Science identifies shifting weather patterns and ocean conditions as among the reasons for the collapse, which spells trouble for the Gulf of California's marine ecosystems and fishery-dependent economies. It could also be a sign of things to come elsewhere.
A total of 55 animal species in the UK have been displaced from their natural ranges or enabled to arrive for the first time on UK shores because of climate change over the last 10 years (2008-2018) - as revealed in a new study published today (18 July 2019) by scientists at international conservation charity ZSL (Zoological Society of London).
In the 1960s, Penn biologist Dan Janzen, as part of earning his Ph.D., re-described what has become a classic example of biological mutualism: the obligate relationship between acacia-ants and ant-acacia trees. The acacia trees produce specialized structures to shelter and feed the ant colony, and the ants, in turn, defend the tree against herbivores.
Giving credence to the saying, "While the cat's away, the mice will play," a new study indicates that pumas and medium-sized carnivores lie low when they sense the presence of humans, which frees up the landscape for rodents to forage more brazenly.
Young Australian eastern blue-tongue lizards (Tiliqua scincoides) are every bit as clever as adults, researchers have found.
Researchers from the National Museums of Kenya, University of Arkansas, University of Missouri and Duke University have announced the discovery of a tiny monkey that lived in Kenya 4.2 million years ago.
Many dinosaur species are known from scant remains, with some estimates suggesting 75% are known from five or fewer individuals. Auroraceratops rugosus was typical in this regard when it was named in 2005 based upon a single skull from the Gobi Desert in northwestern China. But that is no longer the case.
A new study led by Mitch Irwin and Karen Samonds of Northern Illinois University finds that degraded rainforest habitats are having an unhealthy impact on at least one species of Madagascar's treasured lemurs, the most endangered mammal group in the world.
Rising temperatures could mean no male loggerhead turtles hatch at a key breeding ground by the end of this century, new research suggests.
Scientists have known insects experience something like a pain since 2003, but new research published today from Associate Professor Greg Neely and colleagues at the University of Sydney proves for the first time that insects also experience chronic pain that lasts long after an initial injury has healed.
The most extensive and systematic insect monitoring program ever undertaken in North America shows that butterfly abundance in Ohio declined yearly by 2%, resulting in an overall 33% drop for the 21 years of the program.
A University of Otago-led study is heralding advances in our understanding of one of the most startling transformations in the natural world - the complete reversal of sex that occurs in about 500 species of fish.
Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients. Most plants have developed a root system for the nutrients they need in order to survive out of the soil. But what if nutrient-poor soils fail to provide the necessities of life? Carnivorous plants such as the Venus flytrap have found a way out of this dilemma.
