Time-Restricted Eating Reshapes Gene Expression Throughout the Body

Biology
Timed caloric intake synchronizes circadian rhythms across several systems in mice by influencing numerous gene expressions, found researchers at Salk Institute Key Points: Time- restricted eating (TRE) is an eating pattern characterized by limiting food intake to a...

Early Life Experiences Can Have Long-Lasting Impact on Genes

Biology
A new study on fruit flies led by UCL scientists demonstrates that early life events can have a lasting effect on the activity of our genes and even on our longevity. In the study, which was published...

Why Some People Are Mosquito Magnets

Biology
Why some people are 'moquitos magnets'? A recent study revealed that some molecules originating from the skin may provide a potent odor that mosquitoes cannot resist.

Genes Linked with a Longer Lifespan in Humans

Biology
A group of genes that play an essential role in building components of our cells can also impact human lifespan, finds a new study led by UCL researchers.

Modern Humans Developed a More Effective Protection Against Oxidative Stress

Biology
The ancestral variant of glutathione reductase, a key anti-oxidative stress enzyme, produces more reactive oxygen than the modern human variant does.

Blueprint Reveals How Plants Build a Sugar Transport Lane

Biology
A tiny region at the root tip is responsible for the growth and development of the complex network of vascular tissue that transports sugars through plant roots.

Protein that Helps Us Maintain Memories Identified

Biology
Japanese researchers identified a protein that plays a crucial in retaining memories by biding with the Chi factor and regulating certain neurotransmitters.

Biomaterial Can Repair Hearts, Muscles, and Vocal Cords

Health & Medicine
Scientists from McGill University have developed a biomaterial to repair the heart, muscles, and vocal cords—a major advance in regenerative medicine.

Sense of Smell Is Our Most Rapid Warning System

Biology
Negative smells associated with unpleasantness or unease are processed earlier than positive smells and trigger a physical avoidance response.

Overlooked DNA Answers What Makes Us Human

Biology
A previously overlooked part of our DNA, so-called non-coded DNA, appears to contribute to a difference that may explain why our brains work differently.

Warming Climate is Causing Animals to “Shapeshift”

Earth & Climate
Some animals are developing larger beaks, legs, and ears as a result of climate change in order to better control their body temperatures as the earth gets hotter.

Human Cells Can Write RNA Sequences into DNA

Biology
Mammalian cells can convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells, a new study from Thomas Jefferson University reports.

Darwin Foreshadowed Modern Scientific Theories

Biology
Darwin's 'Descent of Man' foreshadowed cooperation, social learning, and cumulative culture' as the keys to our evolution that modern science has reinforced.
