The longest animal in the world, the bootlace worm, which can be up to 55 metres long, produces neurotoxins that can kill both crabs and cockroaches. This has been shown in a new study conducted by researchers at Uppsala University, Linnaeus University and the Swedish Species Information Centre at the Swedish University of Agricultural Sciences....
Vulnerability and extinction risk of migratory species from different regions and ecosystems worldwide
Forty million miles of major roads crisscross the Earth's continents -- enough to circle the planet 1,600 times. For humans, these thoroughfares are a boon, enabling them to move with ease from place to place. But for migrating animals who are also hemmed in by dams, rivers, shipping lanes, urban development and agriculture, they create...
Paleontologists put the bite on an ancient reptile from New England
Scientists have identified a new species of reptile from prehistoric Connecticut and, boy, does it have a mouth on it.
Named Colobops noviportensis, the creature lived 200 million years ago and had exceptionally large jaw muscles -- setting it apart from other reptiles at the time. Even compared to the wide diversity of reptile species today,...
Non-psychoactive cannabis ingredient could help addicts stay clean
A preclinical study in rats has shown that there might be value in using a non-psychoactive and non-addictive ingredient of the Cannabis sativa plant to reduce the risk of relapse among recovering drug and alcohol addicts. The study's findings inform the ongoing debate about the possible medical benefits of non-psychoactive cannabinoids, and the way that...
Rival competition makes ant sperm better swimmers
Ant sperm recognize rival sperm and become more mobile, faster and straighter swimmers as a result, according to a study published in the open access journal BMC Evolutionary Biology. The study looked at the factors that modify sperm behavior when there is competition with sperm from other males in a social insect which only mates...
Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought
We have only known about the existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk.
New Oxford University research suggests that past environmental changes may have profoundly impacted the...
