Researchers recently found a new species of scale worms (Annelida: Polynoidae) living mostly in pairs with a striking difference compared to the almost 900 already known species of scale worms: one was a quarter the size of its mate.
New research focused on interactions among microbes in water suggests fungal microparasites play a bigger than expected role in aquatic food webs and the global carbon cycle.

Facing the triple threat of climate change, loss of nature and pollution, the world must deliver on its commitment to restore at least one billion degraded hectares of land in the next decade - an area about the size of China. Countries also need to add similar commitments for oceans, according to a new report by the UN Environment Programme (UNEP) and the Food and Agriculture Organization of the UN (FAO), launched as the UN Decade on Ecosystem Restoration 2021-2030 gets underway.

It is estimated that canines possess up to 300 million olfactory receptors in their nose, compared to about 6 million in humans. Not only that, but the part of a dog s brain devoted to analyzing smells is about 40 times greater than in humans.
Therefore, it s no wonder pooches are extremely useful tools in the job of detection, whether they re finding explosives, drugs, chemicals or myriad substances. In the last several years, detection canines have increased in popularity, deployment and success as environmental surveyors for range and wildlife species. Their ability to detect species in the environment has even shown to be more reliable in some cases than standard surveying technologies.
