Doudna’s Confidence in CRISPR’s Research Potential Burns Bright
Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.
How the Brain Creates a Timeline of the Past
The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.
The Brain Maps Out Ideas and Memories Like Spaces
Emerging evidence suggests that the brain encodes abstract knowledge in the same way that it represents positions in space, which hints at a more universal theory of cognition.
A ‘Self-Aware’ Fish Raises Doubts About a Cognitive Test
A report that a fish can pass the “mirror test” for self-awareness reignites debates about how to define and measure that elusive quality.
New AI Strategy Mimics How Brains Learn to Smell
Machine learning techniques are commonly based on how the visual system processes information. To beat their limitations, scientists are drawing inspiration from the sense of smell.
You Are Getting Sleepy — Tagged Proteins May Point to Why
The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.
‘Functional Fingerprint’ May Identify Brains Over a Lifetime
A unique neurological “functional fingerprint” allows scientists to explore the influence of genetics, environment and aging on brain connectivity.
A Math Theory for Why People Hallucinate
Psychedelic drugs can trigger characteristic hallucinations, which have long been thought to hold clues about the brain’s circuitry. After nearly a century of study, a possible explanation is crystallizing.
To Remember, the Brain Must Actively Forget
Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.
