Scientists have developed a ground-breaking method for testing the quality of a sperm before it is used in IVF and increase the chances of conception.
There may be a simple way to address racial bias: Help people improve their ability to distinguish between faces of individuals of a different race. Brown University and University of Victoria researchers learned this through a new measurement system and protocol they developed to train Caucasian subjects to recognize different African American faces.
A four-week expedition to explore the deep ocean south-west of Tasmania has revealed new species of animals and more evidence of impacts of increasing carbon dioxide on deep-sea corals.
A new species of fish from tropical South America is confirming suspected roots to the loricariid catfish family tree. Lithogenes wahari shares traits with two different families of fish: the bony armor that protects its head and tail, and a grasping pelvic fin that allows it to climb vertical surfaces.
Scientists studying climate change have long believed that while most of the rest of the globe has been getting steadily warmer, a large part of Antarctica – the East Antarctic Ice Sheet – has actually been getting colder. But new research shows that for the last 50 years, much of Antarctica has been warming at a rate comparable to the rest of the world. In fact, the warming in West Antarctica is greater than the cooling in East Antarctica, meaning that on average the continent has gotten warmer, said Eric Steig, a University of Washington professor of Earth and space sciences and director of the Quaternary Research Center at the UW.
Living with a female mouse can extend the reproductive life of a male mouse by as much as 20 percent, according to a study conducted by Ralph Brinster and a team of other researchers at the University of Pennsylvania School of Veterinary Medicine. The study was reported online January 22 in the journal Biology of Reproduction.
Fruit farmers in Southern Europe have been struggling for decades in a losing battle against the Mediterranean fruit fly, or Medfly, which is one of the world´s most destructive farm pests, since it lays its eggs in fruit and vegetables. The female can produce up to 800 offspring per season. The larvae or worms feed on the pulp of fruits, tunnelling through it, and reducing the fruit to an inedible mush.
The battle waged by farmers in Croatia and Bosnia and Herzegovina against the Medfly has been fought since the 1940s with insecticides. But the growing export market in the European Union imposes strict rules on pesticide residue limits in food.
So in 2007 Croatia turned to the IAEA for help to apply the most environmentally friendly alternative to insecticide – the Sterile Insect Technique (SIT). There are plans to start implementation next year.
