Renters May Age Faster Than Homeowners, Study Finds

Renters May Age Faster Than Homeowners, Study Finds

Renting a home, rather than owning it outright, may speed up the body's aging process, a new study suggests.

Researchers found that when compared with people who owned their home outright (no mortgage), those who rented showed signs of faster "biological aging" -- which ...

Blood Test Might Help Diagnose Parkinson's Disease Much Earlier

Blood Test Might Help Diagnose Parkinson's Disease Much Earlier

As it stands, no one blood test or brain scan can definitively diagnose Parkinson's disease.

But researchers report this may soon change if a new blood test continues to show promise.

The test measures DNA damage in the mitochondria of cells, which is known to be h...

Could Loss of the Y Chromosome Help Speed Cancers in Men?

Could Loss of the Y Chromosome Help Speed Cancers in Men?

It's common knowledge that loss is a part of male aging -- loss of hair, loss of muscle tone, loss of vision or hearing.

But men growing older also start losing the very thing that makes them biological males, their Y chromosome, and that can leave them more vulnerable t...

A More Diverse Human Genome: The 'Pangenome'

A More Diverse Human Genome: The 'Pangenome'

Last year, gene researchers made news by announcing the completion of the first complete sequence of the human genome.

That effort has now been expanded, with researchers using that success as a springboard to create a comprehensive and sophisticated collection of genome...

Smoking or Vaping? The DNA Damage May Be the Same

Smoking or Vaping? The DNA Damage May Be the Same

A new study builds upon earlier evidence that vaping isn't any healthier than smoking.

In analyzing epithelial cells taken from the mouths of vapers, smokers and people who had never vaped or smoked, researchers found that vapers and smokers had more than twice the amoun...

Your Dog's Behavior Is in Its DNA

Your Dog's Behavior Is in Its DNA

Is your pooch a herder or a hunter? You can try taking them to a trainer, but new research shows much of their behavior is hardwired in their DNA.

For the new study, researchers analyzed DNA samples from more than 200 dog breeds and surveyed 46,000 pet-owners to try to s...

Unrelated Folks Who Look Alike Share Similar DNA

Unrelated Folks Who Look Alike Share Similar DNA

A person's unrelated lookalike, commonly known as a doppelganger, may actually share genes that affect not only how they appear, but also their behavior.

In a new study, scientists did DNA analysis on 32 sets of virtual twins -- people with strong facial similarities -...

Major Gene Study Spots DNA Tied to Autism, Other Disorders

Major Gene Study Spots DNA Tied to Autism, Other Disorders

More than 70 genes are very strongly associated with autism and more than 250 are linked to the condition, a major new genetic analysis has revealed.

The analysis is the largest of its kind ...

Ancient DNA Points to Oral Herpes' Beginnings

Ancient DNA Points to Oral Herpes' Beginnings

While the herpes virus that causes lip sores is common today, it has been difficult for scientists to find traces of it among ancient remains.

Now, researchers report they h...

Could an Experimental Cancer Drug Help Treat Spinal Injury?

Could an Experimental Cancer Drug Help Treat Spinal Injury?

A drug in development as a cancer therapy may also help the body regenerate damaged nerves after spinal injuries, new research suggests.

Scientists at the University of Birmingham in the United Kingdom report that they used cell and animal models to show that the drug, d...

Genetic Sign of Aging Linked to Risk of Fatal COVID

Genetic Sign of Aging Linked to Risk of Fatal COVID

It's known that certain chronic health conditions up the odds of death from COVID-19. Now, new research identifies another risk factor.

Shorter telomeres are associated with an increased likelihood of death from COVID-19, particularly in older women, researchers say.

Job Done: Scientists Fill in Missing Gaps to Complete Map of Human Genome

Job Done: Scientists Fill in Missing Gaps to Complete Map of Human Genome

The Human Genome Project produced the most complete map of human genetics ever assembled in 2003 - but that map still held many uncharted territories.

It did not contain about 8% of the human genome, representing crucial regions and large gaps that have remained hidden f...

Did Your Gene Screen Turn Up Dangerous DNA? Study Finds Real Risk Is Low

Did Your Gene Screen Turn Up Dangerous DNA? Study Finds Real Risk Is Low

Most gene variants that have been labeled "pathogenic" may make only a small difference in a person's risk of actually developing disease, a new study suggests.

Scouring genetic data on more than 72,000 individuals,

Scientists ID Genes That Make Your Fingerprints

Scientists ID Genes That Make Your Fingerprints

Your fingerprints may be more than a surefire way to identify you: New research suggests their patterns may be linked to genes that guide limb development.

"People may wonder why our team is working on fingerprints," said co-senior study author Sijia Wang, a geneticist a...

Zoo Study Finds Animal DNA Floating in Air

Zoo Study Finds Animal DNA Floating in Air

Take a whiff of the air in a zoo and you could breathe in the animals' DNA -- not just the smell of the food they eat or their waste, a new study suggests.

Sampling the air from local zoos, two teams of researchers collected enough DNA to identify the animals nearby. The...

Love Black Coffee & Dark Chocolate? It Could Be in Your DNA

If you like your coffee black, it could be that your grandpa or your great-aunt did, too.

A preference for black coffee and also for dark chocolate seems to lie in a person's genes, scientists report.

It's not the taste that these individuals actually love, but it...
