Solving A Dragonfly Flight Mystery:

Dragonflies adjust their wing motion while hovering to conserve energy, according to a Cornell University study of the insect’s flight mechanics. The revelation contradicts previous speculation that the change in wing motion served to enhance vertical lift.

Mice Teeth Explain The Troubles With Human Wisdom Teeth:

During evolution, many of a species’ properties are shaped by ecological interactions. This is readily evident in mammalian teeth, whose many features closely reflect what each species eats. However, for a long time scientists have suspected that genetic and developmental interactions may also influence species-specific properties. Now, researchers at the University of Helsinki’s Institute of Biotechnology show how development affects the evolution of teeth, and have devised a simple developmental model to predict aspects of teeth across many species. The results were published in Nature.

Vitamin C Is Essential For Plant Growth:

Scientists from the University of Exeter and Shimane University in Japan have proved for the first time that vitamin C is essential for plant growth. This discovery could have implications for agriculture and for the production of vitamin C dietary supplements.

New Animal And Plant Species Found In Vietnam:

World Wildlife Fund scientists have just announced the discovery of 11 new animal and plant species in a remote area in central Vietnam. They say this underscores the importance of conservation efforts in the ancient tropical forests of the region.

Primate Sperm Competition: Speed Matters:

Researchers at UC San Diego and UC Irvine have found evidence that supports the theory that reproductive competition during the evolution of primate species has occurred at the level of sperm cell motility.

Clever Plants ‘Chat’ Over Their Own Network:

Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen reveals that plants have their own chat systems that they can use to warn each other.
