We inherit more than just genes

We inherit more than just genes

We are more than the sum of our genes. Epigenetic mechanisms modulated by environmental cues such as diet, disease or lifestyle take a major...
Why do people and animals naturally favor one side over the other?

Why do people and animals naturally favor one side over the other?

Most left-handers can rattle off a list of their eminent comrades-in-arms: Oprah Winfrey, Albert Einstein, and Barack Obama, just to name three, but they...
Study of 52,000 men uncovers the genetics underlying male pattern baldness

Study of 52,000 men uncovers the genetics underlying male pattern baldness

A genomic study of baldness identified more than 200 genetic regions involved in this common but potentially embarrassing condition. These genetic variants could be used...
How Bacterium Survives in Oxygen-Poor Environments

How bacterium survives in oxygen-poor environments

Columbia University biologists have revealed a mechanism by which bacterial cells in crowded, oxygen-deprived environments access oxygen for energy production, ensuring survival of the...
Ancient Easter Island inhabitants had early contact with Native Americans

Ancient Easter Island inhabitants had early contact with Native Americans?

Maybe not. Rapa Nui (Easter Island, Chile) has long been a source of intrigue and mystery. How did such a small community of people build so...
Our body clocks cause wounds sustained at night to heal more slowly

Our body clocks cause wounds sustained at night to heal more slowly

A new study has discovered how our body clocks cause wounds, such as cuts and burns, to heal approximately 60% faster if the injury...

Meditation and yoga can ‘reverse’ DNA reactions which cause stress

Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don't simply relax us. They can 'reverse' the molecular reactions in our DNA which cause...

Signs of life on Mars? Look for the element vanadium

The search for biology on neighbor planet Mars won't play out like a Hollywood movie starring little green men. Rather, many scientists agree if there...
Some Cancers Love Sugar More Than Other Cancers

Some cancers love sugar more than other cancers

In a new study, scientists at The University of Texas at Dallas have found that some types of cancers have more of a sweet...
Manipulating mitochondrial networks could promote healthy aging

Manipulating mitochondrial networks could promote healthy aging

Manipulating mitochondrial networks inside cells—either by dietary restriction or by genetic manipulation that mimics it—may increase lifespan and promote health, according to new research...
