May We All Have The Option of Double Mastectomy

masectomy-small

In the future, may we all have the option to get a double mastectomy. Or, rather, its equivalent for whatever cancer each of us are genetically predisposed to.

FDA Was Right to Block 23andMe

A few techno-libertarians are up in arms over the FDA’s letter warning the genetics company 23andMe to stop selling its personalized genome services kit. But a quick search of the Food and Drug Administration’s admittedly user-unfriendly website shows federal regulators have been targeting various low-cost genetic testing ventures to provide the necessary analysis that goes [...]

New colorectal cancer test could eliminate need for colonoscopy for many people

genetic colorectal screening could reduce colonoscopies

Colonoscopies might beat out root canals as the most reviled commonplace medical procedure that many of us might expect to undergo. Nevertheless, the uncomfortable undertaking is currently one of the best ways to detect early signs of colorectal cancer, a disease that more than 142,000 Americans are diagnosed with each year—and one that kills more [...]

Regulators consider more rigorous examination of consumer genetic tests for serious diseases

consumer genetic test

Whether you have questions about your ancestry, earwax or Alzheimer’s risk, a recent slew of genetic tests promise to give you highly personal answers. Since this summer, however, the U.S. government has been taking a closer look at establishing standards of availability—and accuracy—for direct-to-consumer (DTC) genetic tests. Some 90 percent of these tests have not [...]

Should consumers have the right to buy any genetic test?

should genetic tests be marketed directly to consumers?

Earlier this year, consumers were close to being able to pick up a saliva-based genetic test for disease risk the next time they ran to the drug store for aspirin or sunscreen. But even though the tests are still available for purchase online, consumers, geneticists and other groups quickly started to ask questions about the [...]

Genetic ancestry testing is an inexact science, task force says

genetic ancestry testing task force report

As store-based distribution of genetic health tests remains stalled pending federal review, genetic ancestry tests are also drawing widespread concern from experts. A task force report commissioned by the American Society for Human Genetics and led by Charmaine Royal of the Institute for Genomic Sciences & Policy at Duke University has called for better research [...]

Common Octopus Proves Uncommonly Difficult to Define

The seemingly ubiquitous common octopus (Octopus vulgaris) is our platonic octopus ideal. Even if Plato didn’t write about it, Aristotle did. And since then, it has been the most widely studied (and consumed) species. But contemporary science is complicating things, a new paper, published this month in the journal Frontiers in Ecology and Evolution, details. The [...]

The grandmother and her genes: a grandson’s perspective

Photo by redwood1

Somewhere deep in my grandmother’s veins, a blood clot breaks free. Her blood carries the clot past her heart, to her lungs, where it becomes stuck in a pulmonary artery. This is when my grandmother feels a sudden sting in her chest and loses her breath. She is suffering a pulmonary embolism. My grandmother is [...]
