A new study has helped researchers figure out that men prefer women with a theoretically optimal angle of lumbar curvature because of an evolutionary reason. The study, conducted by researchers at the University of Texas at Austin, showed that even prehistoric men probably liked women with a curvy backside.

The men involved in the study rated women the highest who had a 45.5-degree curve from back to buttocks. The researchers said that women with this spinal structure were preferred by men even in ancient times because it would have helped pregnant women to balance their weight over the hips. Moreover, these women would have been the best at foraging during pregnancy without suffering spinal injuries.

A novel study published in the journal JAMA Pediatrics has found that using chefs in schools led to better results as children ate more fruits and vegetables. Researchers from Harvard University's T. H. Chan School of Public Health conducted a study in which they assessed the eating habit of more than 2,600 children. These children were studying in classes from third to eighth and were from two low-income urban school districts.

Majority of the students were Hispanic and their average age was 11-and-a-half-years. The researchers said that trained chefs were assigned to some schools in order to spice up fruits, vegetables and new dishes having low-fat, low-salt recipes.

A vaccine is being targeted for development by the US government in order to ensure protection of poultry from new strains of avian flu that have recently caused the demise of birds from Arkansas to Washington state.

The vaccine will be tested on chicken within two months by scientists at a US Department of Agriculture (USDA) research lab in Georgia. The test will help researchers determine the efficacy of the vaccine to prevent chickens from contracting illness and succumbing to the virus.

Amy's Kitchen, manufacturer of organic and non-GMO convenience and frozen foods, has recalled over 74,000 meals on account of a potentially deadly bacteria. The decision was taken by the manufacturer when it was warned by one of spinach suppliers that Listeria has been found in their products.
