The aftermath of BP oil spill: mutant seafood

mutant shrimp3244

Signs of the impact on the regional ecosystem are ominous: mutated shrimp, fish with oozing sores, underdeveloped blue crabs lacking claws, eyeless crabs and shrimp – and scientists and fishermen point fingers towards BP’s oil as being the cause.

Two years after BP’s Deepwater Horizon oil spill in the Gulf of Mexico, fishermen are finding deformed fish and mutant shrimp in their seafood catch…

Japanese scientists have produced a genetically-engineered mouse that tweets like a bird, it was revealed today.  A team of researchers at the University of Osaka are breeding genetically modified mice that are prone to miscopying DNA and are more likely to develop mutations.

Drug trials used genetic data to target tumors.

Scientists have hailed a ‘penicillin moment’ in cancer treatment following trials of a drug that uses genetic data to target the formation of specific tumors.  The study has raised hopes drug manufacturers will be able to tailor drugs to individual cancers that will halt them in their tracks and even reverse the growth of existing tumors.

Smokers experience one mutation to their DNA for every 15 cigarettes they smoker, according to a study that mapped out the genetic blueprint of a lung cancer patient.  British researchers led the massive international project, which identified 23,000 mutations that bore the expected signs of damage caused by chemicals in tobacco smoke.

6 Hours of Sleep Not Enough Say Scientists

sleep

Scientists have good and bad news for hard-driving people who boast they need only six hours of sleep a night. The good news is a few may be right: Researchers at the University of California-San Francisco have identified a family with a genetic mutation that causes members to require only six hours sleep a night. The bad news? The gene is vanishingly rare in humans, found in less than 3% of people.

A Source Of Stem Cells From Men

A Source Of Stem Cells From Men 

 Stem cells from adult human testes normally produce only sperm, but when cultured in the lab with special growth factors, they begin to resemble embryonic stem cells and can differentiate into many adult cell types.

Stem cells from human testes could be used for personalized medicine.  Adult stem cells that behave much like embryonic ones have been isolated from human testes, raising hopes for a new source of versatile stem cells without genetic manipulation or the destruction of embryos. If the new stem cells can be used therapeutically, a simple testicular biopsy could provide the starting material for personalized regenerative medicine.

Researchers Agree There Is No Such Thing As A Safe Suntan

Researchers Agree There Is No such Thing As A Safe Tan

There is no such thing as a safe tan, U.S. and British researchers said on Thursday.

They said in their review of published studies that tans and skin cancer both begin with DNA damage caused by exposure to ultraviolet light but many people, especially the young, ignore or are unaware of this danger in a quest for a bronzed body.
