Save Us From Our Frankensteins, Genome-Editing Scientists Urge

A new laboratory technique enables biologists to “edit” the genetic makeup of entire species for purposes ranging from the benevolent to the nefarious, with the “potential to cause ecological mayhem,” Antonio Regalado reports in MIT Technology Review.

Do We Choose Friends With Similar DNA?

A new study, which the researchers themselves are calling “unusual,” posits that friends share more genetic markers than do strangers.

A Troublesome Inheritance

Is there a topic more divisive than race? If so, perhaps it’s the pairing of science and race.

Human Dietary Supplement Linked to Longer Life in Mice

An over-the-counter supplement designed to ease osteoarthritis prolonged the lifespan of lab mice by nearly a tenth, scientists said Tuesday.

Being Gay Is Only Partly Attributable to Genes, Study Finds

A study of gay men found evidence that male sexual orientation is influenced by genes, but not entirely, U.S. researchers say.

Cut-and-Paste DNA May Eliminate HIV

“Researchers have created genetically modified monkeys with a revolutionary new procedure that enables scientists to cut and paste DNA in living organisms,” a development that could “lead to a new era of genetic medicine,” The Guardian reports.

Study: Obesity Gene May Help Prevent Depression

The same gene that may be increasing your girth may also be making you happier, according to a new report.

Scientists Turn DNA Into a Virtually Limitless Storehouse

The successful translation of a book into genetic coding suggests that the building blocks of life could be used to store data cheaply, durably and with staggeringly little space compared with conventional digital devices.

Researchers report that a gene variation that appears more frequently in women than men may help explain the long-established fact that females are more likely to develop the debilitating disease.

And Now, This Neanderthal News Update

Take this one to the Creation Museum: A team of researchers has advanced the idea, in a new journal article published in Molecular Biology and Evolution, that our Neanderthal cousins had mostly died out by the time we Homo sapiens entered the evolutionary scene in full force.

Study: Men May Stick Around for More Than 5M Years

What a relief to know that men might not be an endangered species with a potential expiration date in only 5 million years, according to a new study published, appropriately (if heavy-handedly), in a journal called Nature. The issue boils down to a predicted, but now contested, process of genetic decay targeting the man-specific Y chromosome.

The Amazing Spider-Goat!

This is the kind of scientific story that’s a little “ooh” with some “ew!” mixed in, too: Scientists at Utah State University have cleverly combined goat and spider genes to make a normal-looking strain of goat that happens to be able to produce extra protein in its milk that can be made into spider silk.

Autism Study Shifts Focus From Nature to Nurture

Research on autism in recent decades has emphasized the contributing role of genetics, but a new study out of UCSF and Stanford might prove to be a game-changer, ranking environmental factors (e.g., parenting) higher than biology in order of importance.

Scientists Create ‘Synthetic Cell’

A team of U.S. scientists has created what they’re calling a “synthetic cell,” although really it appears to be more of a Franken-cell, if you will, since the cell’s genome is artificial but the “recipient cell” is not. All the same, it’s still bound to freak some people out.

Study Says Fido’s Family Tree Has Arabian Roots

A research team out of UCLA thinks it may have traced the pedigree of domesticated dogs back to their earliest origins, and the paw prints apparently lead to the general vicinity of the Middle East, instead of the East Asian region they’d previously targeted.

Where Does Genius Come From?

Tracing talent to its origins probably isn’t ever going to be a precise science, but there’s a particular and pervasive brand of genetic determinism that butts its way into discussions, in scientific circles and in the media, about everything from health to intelligence to the roots of genius. According to author David Shenk, this line of argument leads us to make the wrong conclusions about human potential.

Science Diet: It’s in the Genes

Low carb or low fat? Diet trends have led to diet debate. Luckily, some actual scientists are weighing in. The preliminary results of a small study suggest that some of us just process food differently, and picking the right diet based on a gene test could shed two to three times more weight.

Not All Swine Flu News Is Bad

Of course, nobody knows for sure how the H1N1 swine flu virus might morph in the future, but the word from the science community suggests that the current strain may not be quite as catastrophic as it’s been cracked up to be.

Genes Under Pressure

While heart disease remains the No. 1 killer of people in the U.S., researchers have found that we can help explain a large part of these cases through one’s genetic makeup. In fact, one in five white people are believed to have the “blood pressure gene,” where the genetic variance that controls salt in the kidneys changes to affect individuals’ blood pressure.

DNA Scientist Apologizes for Race Remarks

Nobel-winning scientist James Watson, half of the DNA-pioneering team Watson and Crick, is undergoing a firestorm of criticism for recent comments he made in London’s Sunday Times about how he was “inherently gloomy about the prospect of Africa” because “all our social policies are based on the fact that their intelligence is the same as ours—whereas all the testing says not really.”

Baby Shark Conceived Without Father

In one of the more startling scientific discoveries of late, two teams of researchers have found that a baby hammerhead born in a Nebraska aquarium six years ago was conceived via parthogenesis—i.e., without the genetic contribution of a male.

Franken-Heifers Immune to Mad Cow

Using a combination of genetic engineering and cloning, scientists from the U.S. and Japan have successfully eliminated the protein that causes mad cow disease. So far the cows in the lab have proven immune to the illness, which shreds its victims’ brains, driving them mad.

Cloned Food to Go Unmarked

The Food and Drug Administration is set to approve food products derived from cloned animals and their offspring. Though eating beef from a cloned cow may seem incredibly creepy, the FDA has decided the manufactured twin is just as safe as the original animal, and requires no special identification once in the food supply.
