 MJ's Credit Score: 
 Pretty Crappy 

Plus: DNA tests and sperm samples and paternity questions, oh my!

Aug 28, 09 9:03 AM CDT
(Newser) - If Michael Jackson hadn’t been the King of Pop, he probably would have had trouble getting a loan. His average credit score was a “very low” 563.67, TMZ reports—the average Californian’s is 672. Collections and delinquent accounts contributed to the score, and Barneys even shut... More »

 DNA Evidence 'Easy to Fake' 


Aug 18, 09 4:57 AM CDT
(Newser) - Think DNA evidence is foolproof? In fact, it's so easy to fabricate that "any biology undergrad" could engineer a crime scene, claim scientists in Israel. Raising troubling implications for a legal system that treats DNA as a gold standard, the scientists have demonstrated that DNA samples are vulnerable to... More »

(Newser) - A new DNA test proves John Edwards is the father of ex-mistress Rielle Hunter's daughter, the National Enquirer reports. (Yep, it's the Enquirer, but remember they broke news of the affair before any of the mainstream media and forced Edwards into a televised confession.) And it gets worse: Hunter... More »

DNA Screening May Help Beat Ovarian Cancer

55% of women carry variant placing them
at a higher risk

Aug 3, 09 6:20 AM CDT
(Newser) - An international coalition of geneticists has discovered a DNA variant in women with ovarian cancer that could lead to earlier detection and lower mortality rates, reports the Guardian. More than half of women exhibit the genetic trait, which increases the likelihood of ovarian cancer by up to 40%. The researchers... More »

 Mammals Evolve Faster 
 in Hot Weather: Study 

Faster metabolism thought to be why

Jun 24, 09 2:44 PM CDT
(Newser) - Evolution happens faster in warmer climates, a new study finds. Researchers found that DNA changes more frequently among mammals in the species-rich tropics than among comparable species elsewhere, the BBC reports. Scientists believe the germ cells that become sperm and eggs divide more often in hotter weather, perhaps because those... More »

Scientists spark furor with controversial DNA theory

Apr 18, 09 4:20 PM CDT
(Newser) - The genes that make European Jews susceptible to deadly diseases may also increase their intelligence, two scientists say. Arizona physicist Gregory Cochran stumbled on the theory when pondering why natural selection hasn't removed bad DNA from the gene pool that makes Ashkenazi Jews get so many diseases. His answer: ...
