Dinosaur hunters on a month-long expedition to the Sahara desert have returned home in time for Christmas with more than they ever dreamed of finding. They have unearthed not one but two possible new species of extinct animals. Their success marks one of the most exciting discoveries to come out of Africa for 50 years.
As polar bears adapt to a warming Arctic--a frozen seascape that cleaves earlier each spring--they may find relief in an unlikely source: snow goose eggs. New calculations show that changes in the timing of sea-ice breakup and of snow goose nesting near the western Hudson Bay could provide at least some polar bears with an alternative source of food. This new analysis appears in Polar Biology.
A map of natural hazard mortality in the United States has been produced. The map gives a county-level representation of the likelihood of dying as the result of natural events such as floods, earthquakes or extreme weather.
Scientists are expanding the search for extraterrestrial life -- and they've set their sights on some very unearthly planets. Cold "Super-Earths" -- giant, "snowball" planets that astronomers have spied on the outskirts of faraway solar systems -- could potentially support some kind of life, they have found.
MIT researchers have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain.
As the cold weather creeps in, so do brown recluse spiders. True to their name, the brown recluse is a shy, reclusive spider looking for a warm home. Drawn to clutter, closets and complex storage environments, the spiders actually want to stay away from humans. But, if care is not taken, people could find themselves sharing their home with one of 'the big three,' according to a University of Missouri entomologist.
A group of five endemic and recently extinct Hawaiian songbird species were historically classified as "honeyeaters" due to striking similarities to birds of the same name in Australia and neighboring islands in the South Pacific. Scientists at the Smithsonian Institution, however, have recently discovered that the Hawaiian birds, commonly known as the oo's and the kioea, share no close relationship with the other honeyeaters and in fact represent a new and distinct family of birds--unfortunately, all of the species in the new family are extinct, with the last species of the group disappearing about 20 years ago.
A leading UK plant scientist has called for the application of new in-depth data analysis of plants' natural control systems to enable plant breeders to develop varieties that are naturally less conservative.
A research project led by Michel AndrÃ©, director of the Laboratory of Applied Bioacoustics at the UPC (Universitat PolitÃ¨cnica de Catalunya) has developed the world's first portable system for measuring cetacean hearing sensitivity.
Spanish researchers have shown that the salinity of sea water could act as a "barrier", preventing the turtles from moving between the areas of the Western Mediterranean. This is why loggerhead turtles from the south and north of the Western Mediterranean do not mix as juveniles. This finding could help in the development of measures to protect this migratory species.
Feeling threatened? Hungry? Looking for a mate? Move! Tracking and remote sensing data are making it easier to locate organisms and find out what they are up to. However, general theories of movement are lacking. In a special feature on Movement Ecology in the journal Proceedings of the National Academy of Sciences, researchers present integrative models for movement of organisms as diverse as gut bacteria, tree seeds, ants, marine larvae and cheetahs.
What began as an homage to achievement in the field of coral reef geology has evolved into the discovery of an unexpected link between corals of the Pacific and Atlantic. Dr. Ann F. Budd from the University of Iowa and Dr. Donald McNeill of the University of Miami named a new species of fossil coral found on the Island of CuraÃ§ao - some six million years old - after renowned coral reef geologist and University of Miami Rosenstiel School professor, Dr. Robert N. Ginsburg.
While harnessing more energy from the wind could help satisfy growing demands for electricity and reduce emissions of global-warming gases, turbulence from proposed wind farms could adversely affect the growth of crops in the surrounding countryside.
In the search for life beyond Earth, scientists 'follow the water' to find places that might be hospitable. However, every home gardener knows that plants need more than water, or even sunshine. They also need fertilizer - a mixture of chemical elements that are the building blocks of the molecules of life.
