Dolphins like Natua, pictured here, may share with humans the ability reflect upon their states of mind, says UB researcher David Smith.

Smith makes this conclusion in an article published the September issue of the journal Trends in Cognitive Science (Volume 13, Issue 9). He reviews this new and rapidly developing area of comparative inquiry, describing its milestones and its prospects for continued progress.

Flash Recovery Of Ammonoids After Most Massive Extinction Of All Time

090902122331

Asteroceras, a Jurassic ammonite from England.

After the End-Permian extinction 252.6 million years ago, ammonoids diversified and recovered 10 to 30 times faster than previous estimates. The surprising discovery raises questions about paleontologists’ understanding of the dynamics of evolution of species and the functioning of the biosphere after a mass extinction.

A monkey that has acquired the sole power to hand out apples is generously rewarded with grooming sessions by the other monkeys in its group.

A monkey that has acquired the sole power to hand out apples is generously rewarded with grooming sessions by the other monkeys in its group. But as soon as another monkey can hand out apples as well, the market value of the first monkey is halved. Continue reading… “Monkeys Follow Economic Rules Of Supply And Demand”

The Mexican Free-tailed Bat (Tadarida brasiliensis) lives a very long life compared to closely related animals such as mice

Scientists from Texas are batty over a new discovery which could lead to the single most important medical breakthrough in human history—significantly longer lifespans. The discovery, featured on the cover of the July 2009 print issue of The FASEB Journal, shows that proper protein folding over time in long-lived bats explains why they live significantly longer than other mammals of comparable size, such as mice.

Enlarged microscopic image of sand grains

University of Chicago researchers recently showed that dry granular materials such as sands, seeds and grains have properties similar to liquid, forming water-like droplets when poured from a given source. The finding could be important to a wide range of industries that use “fluidized” dry particles for oil refining, plastics manufacturing and pharmaceutical production.

Sport hunters are depleting lion and cougar populations as managers respond to demands to control predators that threaten livestock and humans.

Sport hunters are depleting lion and cougar populations as managers respond to demands to control predators that threaten livestock and humans, according to a study published in the June 17 issue of PLoS One. The study was led by Craig Packer, a University of Minnesota professor and authority on lion behavior, who worked with an international team of conservationists.

WHICH ONE IS THE LEMUR!!!!!!!

A third species of Palaeopropithecus, an extinct group of large lemurs, has just been uncovered in the northwest of Madagascar by a Franco-Madagascan team. Dubbed Palaeopropithecus kelyus, this new specimen is smaller than the two species of these ‘large sloth lemurs’ already known and its diet made up of harder-textured foodstuffs. This discovery supports the idea of a richer biodiversity in recent prehistory (late Pleistocene and beginning of the Holocene).
