Brain problems killed Knut the polar bear, says Berlin zoo

New York, March 23: Berlin Zoo officials have claimed that Knut the polar bear died of unspecified brain problems.

The 4-year-old celebrity polar bear collapsed in his containment on Saturday in front of several hundred visitors, reports the New York Daily News.

Early findings from a necropsy performed Monday showed "significant changes to the brain, which can be viewed as a reason for the polar bear''s sudden death," the zoo said in a statement.

The zoo didn''t elaborate on what exactly was wrong with the bear''s brain, but it said pathologists found no damage to any other organs.

Whole brain radiation ups cancer patients’ learning, memory problems riskWashington, Sept 23: A new research has found that cancer patients who receive stereotactic radiosurgery (SRS) and whole brain radiation therapy (WBRT) for the treatment of metastatic brain tumours have more than twice the risk of developing learning and memory problems than those treated with SRS alone.


Treating common brain cancer as two diseases could help improve cure

London, September 15 : Genetic studies conducted on patients with glioblastoma, the most common type of brain cancer, in America suggest that this disease should be treated as two disease not one.

Victor Velculescu of the Ludwig Center for Cancer Genetics and Therapeutics in Baltimore, Maryland, says that glioblastoma patients whose cancers carry a mutation in a gene called IDH1 are 20 years younger than those without the mutation, on average.

The study has revealed that cancers carrying the mutation are less aggressive, the researcher says.


How the brain manages fear revealed

Washington, Sept 11 : Although humans may have developed complex thought processes that can help to regulate their emotions, a new research has suggested that the processes are associated with evolutionarily older mechanisms that are common across species.
