Are genes our destiny? 'Hidden' code in DNA evolves more rapidly than genetic code, scientists discover
A "hidden" code linked to the DNA of plants allows them to develop and pass down new biological traits far more rapidly than previously thought, according to the findings of a groundbreaking study by researchers ...

Researchers discover that stem cell marker regulates synapse formation
Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, ...

How cells running on empty trigger fuel recycling
Researchers at the Salk Institute for Biological Studies have discovered how AMPK, a metabolic master switch that springs into gear when cells run low on energy, revs up a cellular recycling program to free ...

Use the common cold virus to target and disrupt cancer cells?
A novel mechanism used by adenovirus to sidestep the cell's suicide program, could go a long way to explain how tumor suppressor genes are silenced in tumor cells and pave the way for a new type of targeted ...

Origins of multicellularity: All in the family
One of the most pivotal steps in evolution-the transition from unicellular to multicellular organisms-may not have required as much retooling as commonly believed, found a globe-spanning collaboration of scientists ...

Lessons from the pond: Clues from green algae on the origin of males and females
A multicellular green alga, Volvox carteri, may have finally unlocked the secrets behind the evolution of different sexes. A team led by researchers at the Salk Institute for Biological Studies has shown ...

The pre-history of life: Elegantly simple organizing principles seen in ribosomes
With few exceptions, all known forms of life on our planet rely on the same genetic code to specify the amino acid composition of proteins. Although different hypotheses abound, just how individual amino acids ...

Seeing without looking
Like a spotlight that illuminates an otherwise dark scene, attention brings to mind specific details of our environment while shutting others out. A new study by researchers at the Salk Institute for Biological ...

Unraveling the mechanisms behind organ regeneration in zebrafish
The search for the holy grail of regenerative medicine -- the ability to "grow back" a perfect body part when one is lost to injury or disease -- has been under way for years, yet the steps involved in this ...

What drives our genes? Researchers map the first complete human epigenome
Although the human genome sequence faithfully lists (almost) every single DNA base of the roughly 3 billion bases that make up a human genome, it doesn't tell biologists much about how its function is regulated. Now, researchers ...

On the move: 'Jumping genes' create diversity in human brain cells
Rather than sticking to a single DNA script, human brain cells harbor astonishing genomic variability, according to scientists at the Salk Institute for Biological Studies. The findings, to be published in ...

How the retina works: Like a multi-layered jigsaw puzzle of receptive fields
About 1.25 million neurons in the retina -- each of which views the world only through a small jagged window called a receptive field -- collectively form the seamless picture we rely on to navigate our environment. ...

Involuntary maybe, but certainly not random
Our eyes are in constant motion. Even when we attempt to stare straight at a stationary target, our eyes jump and jiggle imperceptibly. Although these unconscious flicks, also known as microsaccades, had long ...
