You Can Choose Your Friends But They Could Be Your Family

You can choose your friends but not your family, so the old saying goes. But do we really choose them, or are we genetically pre-disposed to connect with the people in our friendship groups?

People who like to consider their close friends as family may not be too far wrong, according to a new study from the University of California,...

Scientists Creating Human Hybrids in Unregulated Genetic Engineering Programmes

When most people think of genetically modified organisms, or GMOs, pictures of pest-hardy soya beans spring to mind, yet the true implications of this term are not widely considered.

Though the consumption of GMOs is a subject for debate in itself, there are other, less obvious areas in which other...

Weekender: Can Science Locate "Adam", the Earth's First Man?

According to the Bible, the first human man ever to walk the Earth was Adam, created by God and partnered by his female counterpart Eve. Norse mythology shares a similar concept of a deity-created man and woman, though in Norse legend the planet's first couple are entitled Ask and Embla.

Regardless of his given name, the world's...

Supreme Court Decison Nears on Who Owns Your DNA

A few weeks ago, we told you that someone ELSE may own YOUR DNA. Almost every cell in your body contains a copy of your genetic code--can a private company patent it and sell it? The Supreme Court says, "no."

Someone ELSE Owns Your DNA

In the future, doctors will be able to diagnose the diseases we're likely to get, such as heart disease and diabetes, by looking at our DNA. That way, they'll be able to give us concrete advice about our health habits. But what if they have to consult the company who has patented our genes first? You may not know it, but you don't "own"...

Our DNA Doesn't Predict What Will Kill Us

If we could test every infant's DNA at birth, we could predict what future diseases they might have and guard against them early--right? Wrong!

In the April 3rd edition of the New York Times, Gina Kolata quotes researcher Bert Vogelstein as saying, "...

DNA May Not Always Catch the Culprit

We're relying more and more on DNA evidence to catch rapists and murderers, but there's evidence that psychological bias plays a part in how this evidence is interpreted. Labs aren't always as objective as we'd like them to be.

Recently, we've seen cases where DNA evidence freed innocent people from prisons, but sometimes,...

Junk DNA: What's it For?

Scientists have discovered a lot of DNA that we don't seem to have a use for, so they've called it "junk" DNA. But now they may be discovering that it's not just junk, after all. They now think that at least 80% percent of it is active and needed.

The human genome is packed with at least four million gene switches that...

Careful Mom: Spanking Can Change Your Kid's DNA

It's the kind of transformation we DON'T want: Children who are exposed to violence experience wear and tear to their DNA that is similar the changes that come with aging. In a...

The Problem with Police Line Ups

On TV cop shows, victims almost always identify the perpetrators correctly, but real life doesn't work that way: DNA testing has revealed that witnesses often pick out the wrong person, while detectives, in the background, keep telling the person to "take your time." But new studies show that these witnesses should go with their...

We May All be Martians

It's been discovered that DNA can travel on a meteorite, meaning that life on Earth could have been seeded from another planet--maybe even Mars. If that's the case, we don't need to look for life on Mars...

Our DNA is Quantum!

A Nobel Prize winning biologist says that a fragment of DNA "teleported" itself between test tubes in his lab, meaning that it demonstrated the quantum ability of being non-local, i.e. in two places at the same time. What are we...

Ancient DNA--What Can It Tell Us?

Researchers recently revived ancient bacteria that had been trapped for thousands of years in water droplets embedded in salt crystals. Is this a good idea? This bacteria been found inside salt crystals ranging in age from thousands to hundreds of...

Should We Store our DNA in Case Doomsday Comes?

But how and who owns it? - If December 21st, 2012, really does bring ominous news, or an asteroid wipes out most of the life on Earth, the human race won't end if we've stored away some DNA. But it would be stored on computers and no one knows how long computer hard drives could last.

Humans & Aliens May Have Same DNA

And DNA is telepathic! - On the Discovery Channel website, Luke Mckinney reports that all DNA strands are built out of a set of 20 amino acids and scientists now think that the first 10 may occur throughout the universe, meaning they could have arrived on earth on asteroids from deep space for from other planets. And strands of...

Sea Urchins R Us

We may not be related to Neanderthals, but we ARE related to small sea creatures called sea urchins! The Sea Urchin Genome Sequencing Project (SUGSP) Consortium (yes, there is such a thing) has announced that they have succeeded in decoding the DNA of the sea urchin...and found it surprisingly similar to ours.

They found more than 814...

Politics: Some People Were BORN for It!

We've learned that we can't always count on politicians to do the right thing. The recent election shake-up makes us ask the question: "What makes a person go into the rough-and-tumble world of politics, anyway?" The answer could be: DNA.

A research group made up of both political scientists and geneticists is trying to prove that...

A Single Gene Protects, but Two Genes Can Kill

A medical breakthrough of the past few years is the discovery that having only one gene for a deadly disease can protect a person from other illnesses, which is why these diseases, like cystic fibrosis and sickle cell anemia, persist in the human population. This realization came about when it was discovered that sickle cell anemia, a genetic...

Roots...NOT

African-Americans are searching for their roots. However, the researchers have found that only one in 10 African Americans may be able to find clues about their ancestral origins if mitochondrial DNA is tested. Mitochondrial DNA is the portion of the body's genetic code that is inherited from the mother. In recent years, mitochondrial DNA has...

What Did YOU Inherit?

Everyone wants to learn about their roots, which is why so many African-Americans are having their DNA tested. But we don't just inherit our looks and perhaps our personalities?our susceptibility to disease is also inherited, and if we can find out what genes we have, we can deal with these problems before they get too serious.

If You Fidget, It's Genetic

Why do some people seem so calm, even though they may really be frightened, while others fidget constantly, whether they are nervous or not? Some brains may be wired to encourage fidgeting and other restless behaviors, and fidgeting isn't all bad?it uses up calories and helps control your weight.

Chimps R Us

Humans and chimps share about 98% of their DNA, and now scientists have discovered monkeys that can talk to each other?in complete sentences.

Genevi?ve Roberts reports in the Independent that using words to make sentences?and using the same word for the same thing over and over?is what we call "syntax," and putty-nosed monkeys in Africa...

Like to Read? It's Genetic!

Scientists have discovered that, like so many other things, the enjoyment of reading is in your DNA.

Researcher Phillip Dale says, "Children don't come into this world as clay to be molded. They do have their own interests because there is a genetic component" and "It is often more than one gene that determines the interests a child...

Chimps R Us

Scientists have discovered that we share most of our genes with chimps. While we are closely related to great apes, they are not our ancestors. Instead, we share a COMMON ancestor that lived between 5 and 7 million years ago and is no longer around. So what is it exactly that makes us different?

Can Fingerprints be Trusted?

There may be criminals behind bars who shouldn't have been convicted. In recent years, we've seen DNA testing release many of these convicts, often after decades of incarceration. But fingerprints can't be wrong?or can they?

Duncan Graham-Rowe writes in New Scientist that the reliability of fingerprinting is currently being tested in...

Sorry?You're Not the Dad

Ever since DNA testing has allowed us to find out who the father of a baby really is, we drive by huge billboards telling Dads they should get their babies tested before paying child support. There's a reason for this: British researchers have discovered that about 4% of fathers are supporting a child who is not their own.
