Contagious cancer thrives in dogs by adopting host's genes - 2 views

  •  
    An curious contagious cancer, found in dogs, wolves and coyotes, can repair its own genetic mutations by adopting genes from its host animal, according to a new study in the journal Science.

Key information about breast cancer risk and development is found in 'junk' DNA - 0 views

  •  
    "A new genetic biomarker that indicates an increased risk for developing breast cancer can be found in an individual's "junk" (non-coding) DNA, according to a new study featuring work from researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues."

Lies, Damned Lies, and Medical Science - Magazine - The Atlantic - 0 views

  •  
    Much of what medical researchers conclude in their studies is misleading, exaggerated, or flat-out wrong. So why are doctors-to a striking extent-still drawing upon misinformation in their everyday practice? Dr. John Ioannidis has spent his career challenging his peers by exposing their bad science.

BPA and testosterone levels: First evidence for small changes in men - 0 views

  •  
    Researchers have for the first time identified changes in sex hormones associated with bisphenol A exposure in men, in a large population study. BPA is a chemical commonly used in food and drink containers.

Pinpoint Precision: Nanowires Deliver Biochemical Payloads to One Cell Among Many - 0 views

  •  
    "(PhysOrg.com) -- Imagine being able to drop a toothpick on the head of one particular person standing among 100,000 people in a stadium. It sounds impossible, yet this degree of precision at the cellular level has been demonstrated by researchers affiliated with the Johns Hopkins University Institute for NanoBioTechnology. Their study was published online in June in Nature Nanotechnology."

Do we clamp the umbilical cord too soon? - 2 views

  •  
    "The timing of umbilical cord clamping at birth should be delayed just a few minutes longer, suggest researchers at the University of South Florida's Center of Excellence for Aging and Brain Repair."

1 gene lost = 1 limb regained? Scientists demonstrate mammalian regeneration through si... - 1 views

  •  
    "A quest that began over a decade ago with a chance observation has reached a milestone: the identification of a gene that may regulate regeneration in mammals. The absence of this single gene, called p21, confers a healing potential in mice long thought to have been lost through evolution and reserved for creatures like flatworms, sponges, and some species of salamander. In a report published today in the Proceedings of the National Academy of Sciences, researchers from The Wistar Institute demonstrate that mice that lack the p21 gene gain the ability to regenerate lost or damaged tissue."

Vitamin D levels have different effects on atherosclerosis in blacks and whites - 0 views

  •  
    "Vitamin D is quickly becoming the "go-to" remedy for treating a wide range of illnesses, from osteoporosis to atherosclerosis. However, new evidence from a Wake Forest University School of Medicine study suggests that supplementing vitamin D in those with low levels may have different effects based on patient race and, in black individuals, the supplement could actually do harm."

A better genetic test for autism - 2 views

  •  
    "A large study from Children's Hospital Boston and the Boston-based Autism Consortium finds that a genetic test that samples the entire genome, known as chromosomal microarray analysis, has about three times the detection rate for genetic changes related to autism spectrum disorders (ASDs) than standard tests. Publishing in the April issue of Pediatrics (and online March 15), the authors urge that CMA become part of the first-line genetic work-up for ASDs."

Freezing out breast cancer - 0 views

  •  
    "Interventional radiologists have opened the door to an encouraging potential future treatment for the nearly 200,000 women who are diagnosed with breast cancer in the United States each year: image-guided, multiprobe cryotherapy. In the first reported study, researchers were able to successfully freeze breast cancer in patients who refused surgery; the women did not have to undergo surgery after treatment to ensure that tumors had been killed, note researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla."

US scientists warn of fraud of stem cell 'banks' - 0 views

  •  
    "Clinics that offer to "bank" stem cells from the umbilical cords of newborns for use later in life when illness strikes are fraudsters, a top US scientist said here Saturday."

Stanford's Hank Greely puts neuroscience on trial - 0 views

  •  
    "A lawyer is trying to convince a jury that his client really is crazy. It's usually a tough argument to sell in a court of law. But what if the lawyer has a picture of his client's brain that shows there's something biologically wrong with it? Can that evidence help persuade a jury? Should it even be allowed as evidence?"
