Washington, Apr 15 : Purdue University scientists have uncovered new evidence suggesting that factors other than genes could be involved in the development of obesity.

Researchers say they have uncovered evidence that genetically identical cells store widely differing amounts of fat, depending on subtle variations in how the cells process insulin.

Learning the precise mechanism responsible for fat storage in cells could lead to methods for controlling obesity.

Dubai - Scientists in Dubai have created the world's first cloned camel, a local newspaper reported Tuesday. Injaz, or "Achievement," was born at 4:30 pm on April 8, as a healthy female calf, the Emirati daily The National reported on Tuesday. She is the first cloned camel.

Injaz is the result of five years of work by scientists at the Camel Reproduction Centre and the Central Veterinary Research Laboratory in research into strains of camels for racing and milk production.

Washington, April 14 : A new research has shown that chemicals commonly used to clean up oil spills make oil far more toxic to fish, particularly for eggs and young fish.

According to a report by Discovery News, the research was done by Fish toxicologist Professor Peter Hodson of Queen’s University in Kingston, Ontario and colleagues.

Scientists already debate about how best to clean up spills. The new work makes those decisions even more complicated and controversial.

Washington, Apr 14 : Scientists from The University of Texas Health Science Centre at Houston are developing a robotic device to help recovering stroke and spinal cord injury patients.

The prototypes, brainchild of two faculty members in the Laboratory of Adaptive Technologies at The University of Texas Health Science Centre, are armed with a scissor-like claw that can perform a variety of functions, including moving a glass of water or snatching a pen off the floor.

Washington, April 14 : A team of biologists has demonstrated that a group of African fish, known as cichlids, can eat using the help of a non-visual sensory system, which is the first of its kind reported in this species.

Jacqueline Webb, a University of Rhode Island (URI) professor of biology, and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.
