Adults of many animal species play a crucial role in the social development of youngsters. A new study reveals that the ratio of adults to young plays a much more important role in social development than the mere presence of adults.
Until now, Triceratops was thought to be unusual among its ceratopsid relatives. While many ceratopsids–a common group of herbivorous dinosaurs that lived toward the end of the Cretaceous–have been found in enormous bonebed deposits of multiple individuals, all known Triceratops (over 50 in total) fossils have been solitary individuals.
Diagnosed with an extremely aggressive form of cancer called anal sac adenocarcinoma, Oscar’s future seemed bleak. Bedridden and unresponsive to chemotherapy or radiation, he would be lucky to survive three months. But thanks to an innovative new drug treatment, Oscar’s cancer receded and he was walking again within two weeks.
Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphere’s carbon dioxide, yet research by Michigan State University scientists suggests they could become less able to “sequester” that greenhouse gas as the climate warms. The microscopic algae are a major component of plankton living in puddles, lakes and oceans.
The genetic toolkit that animals use to build fins and limbs is the same genetic toolkit that controls the development of part of the gill skeleton in sharks, according to a new study.
Deep-sea corals from about 400 meters off the coast of the Hawaiian Islands are much older than once believed and some may be the oldest living marine organisms known to man.
Maize was domesticated from its wild ancestor more than 8700 years according to biological evidence uncovered by researchers in the Mexico’s Central Balsas River Valley. This is the earliest dated evidence — by 1200 years — for the presence and use of domesticated maize.
When coral colonies meet one another on the reef, they have two options: merge into a single colony or reject each other and aggressively compete for space. Now, a report in the March 19th Current Biology has found a gene that may help to decide that fate.
Virginia Commonwealth University School of Medicine researchers have discovered that adult animals with hearing loss actually re-route the sense of touch into the hearing parts of the brain.
