Scientists at the University of Leicester have captured the first detailed “molecular movie” showing DNA being unzipped at the atomic level — revealing how cells begin the crucial process of copying their genetic material.
The groundbreaking…

Restored stream supports new wild salmon run
Almost everywhere in California, salmon are on the decline. But in Putah Creek — a restored stream running through the University of California, Davis, campus — wild salmon are not only increasing, they also are completing their life cycle.

The cell’s powerhouses: Molecular machines enable efficient energy production
Mitochondria are the powerhouses in our cells, producing the energy for all vital processes. Using cryo-electron tomography, researchers at the University of Basel, Switzerland, have now gained insight into the architecture of mitochondria at…

Babies can form memories, and they do it a lot like adults
A baby’s early life has a lot of milestones: first giggle, first tooth, first step. A brain scanning study adds to the list: first memory.
Infants can form memories, and they use a memory structure in the brain called the…

Why don’t we remember being a baby? New clues in memory mystery.
What’s the earliest memory you can recall? While many people’s recollections of the past may stretch back into childhood, research shows that the trip down memory lane generally hits a wall once you reach infancy. In some ways, this…

Scientists Reveal Why We Can’t Remember Our Earliest Years
A new fMRI study reveals that babies as young as 12 months can encode memories, contradicting theories that memory formation is impossible in infancy. Instead, the inability to recall early life may stem from retrieval failures rather than memory…

Cells That Build Themselves Into an Embryo? Scientists Just Made It Happen
Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show remarkable, collective behavior, almost as if…

Trials Indicate Vagus Nerve Stimulation may Relieve Depression
In clinical trials, almost 500 depression patients who were resistant to current treatments were given therapy that stimulated their vagus nerve. The majority of these patients had such serious depression that…
