A new study demonstrates that eating protein-rich eggs for breakfast reduces hunger and decreases calorie consumption at lunch and throughout the day. The study, published in the February issue of Nutrition Research, found that men who consumed an egg-based breakfast ate significantly fewer calories when offered an unlimited lunch buffet compared to when they ate a carbohydrate-rich bagel breakfast of equal calories.(1) This study supports previous research which revealed that eating eggs for breakfast as part of a reduced-calorie diet helped overweight dieters lose 65 percent more weight and feel more energetic than dieters who ate a bagel breakfast of equal calories and volume.(2) http://phys.org/news189782584.html Medicine & Health Tue, 06 Apr 2010 15:00:02 EST news189782584 Walking through urine drives crayfish into an aggressive sexual frenzy. Researchers writing in the open access journal BMC Biology suggest that a urine-mediated combination of aggressive and reproductive behaviour ensures that only the strongest males get to mate. http://phys.org/news189110353.html Biology Mon, 29 Mar 2010 20:00:02 EST news189110353 Stay and fight, or flee?

The scientists thus hope to offer yet another efficient and promising avenue for supplying produce to the market by eliminating pests without damage to the environment. http://phys.org/news188038133.html Biology Wed, 17 Mar 2010 09:49:29 EST news188038133 A British fertility clinic said Sunday it was raffling off a human egg this week to promote its "baby profiling" service, which it insists is legal under UK law. http://phys.org/news187782594.html Medicine & Health Sun, 14 Mar 2010 10:50:31 EST news187782594 Mother birds communicate with their developing chicks before they even hatch by leaving them messages in the egg, new research by a team from the Department of Zoology, University of Cambridge, has found. http://phys.org/news187537761.html Biology Thu, 11 Mar 2010 14:00:01 EST news187537761 You can catch the hatch of the first egg in the tree-top bald eagle nest at Norfolk Botanical Garden in southeastern Virginia via the garden's special Web cam -- norfolkbotanicalgarden.org. http://phys.org/news187515461.html Biology Thu, 11 Mar 2010 07:39:05 EST news187515461 The potentially deadly yellow-fever-transmitting Aedes aegypti mosquito detects the specific chemical structure of a compound called octenol as one way to find a mammalian host for a blood meal, Agricultural Research Service (ARS) scientists report. http://phys.org/news187357153.html Biology Tue, 09 Mar 2010 12:00:06 EST news187357153 Just because cricket moms abandon their eggs before they hatch doesn't mean they don't pass wisdom along to their babies.
