One can buy defensive stocks like pharma says Dilip Bhat, Joint MD, Prabhudas Lilladher.

Bhat told CNBC-TV18, “We would be more comfortable towards pharmaceutical. It is a great space to be in even now particularly Ranbaxy and Dr. Reddy’s and in the midcap it could be Indoco Remedies.”

He further added, “ Ranbaxy Labs is one story which we are just in the process of doing a detailed coverage but that’s one stock which we feel has a potential to double over next 15-18 months. I think with the FDI approval coming, the stage is set for the core profits to really grow in a very big way for the company and of course the first to file will keep on increasing the cash flows for the company. So that pharmaceutical space looks pretty good, interesting, defensive at the same time chances of getting a reasonable return also appears to be pretty good.”

Japan bees cook enemy in ‘hot defensive bee ball’

By Mariko Lochridge

TOKYO | Thu Mar 29, 2012 2:41pm EDT

TOKYO (Reuters) – Don’t mess with Japanese honeybees. Not only do they cooperate to attack their enemies, researchers now say their brains may actually be processing and responding to the threat.

When confronted with their arch-enemy, the aggressive giant Asian hornet, the honeybees will attack it by swarming en masse around the hornet and forming what scientists call a “hot defensive bee ball” – a move unique to their species.

With up to 500 bees all vibrating their flight muscles at once, the bee ball cooks the hornet to death.

While this defensive maneuver has been known for some time, the mechanism behind it has been shrouded in mystery. But researchers at Japan’s University of Tokyo, through study of the bees’ brains, have now found that neural activity in bees taking part in the attack picks up.

“When the hornet, the Japanese honeybee’s natural enemy, enters a colony, the bees quickly form a ‘hot defensive bee ball,’ trapping the hornet inside and heating it up to 46 degrees C (115 F) with their collective body heat,” said Atsushi Ugajin, a University of Tokyo graduate student.

He said that while the high temperature phase lasts about 20 minutes, it often takes up to an hour before the hornet dies inside the ball.

Set off if bees posted as “guards” at the entrance to the colony detect an intruder, the move evolved because the bee’s stingers aren’t strong enough to penetrate the hornet’s tough exo-skeleton, researchers said.

The research team, whose latest research on the phenomenon appeared in the scientific journal PLoS ONE in mid-March, was astounded by the fact that the collective heat generated by the group, while fatal for the hornet, leaves the bees unaffected.

They were also surprised that the bees used perfectly coordinated teamwork during the process, said Takeo Kubo, a professor at the University of Tokyo graduate school.

“When an outsider enters, the honeybees are immediately on their guard. Then, all at once, they gather to attack,” he said.

“So, it isn’t one commanding all the rest, we believe in this moment of emergency they’re acting collectively.”

Curious about why the bees attack this way, the researchers examined their brains and found that neural activity increased in the bees involved with the bee ball, apparently reflecting processing of thermal stimuli.

The group also said that while this discovery may seem to demonstrate that the Japanese honeybee is “smarter” than its European counterpart, this is not the case – it’s merely a matter of development in response to environmental factors.

“When a member of the colony, a worker drone, is killed, this is a grievous loss for the hive. Evolution has reacted in this way (for their survival),” said Masato Ono, a Japanese honeybee and hornet expert who was also part of the study.

And many fundamental unknowns remain.

“One of the great mysteries for us is how animals’ brains have evolved and how they operate,” Kubo said. “This will be for us the next great puzzle to examine.”
