What Did the Earliest Animals Look Like?

Biology
Biologists have been searching for the earliest animals for more than a century, narrowing the possibilities down to two groups: sponges and comb jellies. Researchers employ a novel method based on chromosome structure in a recent study...

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...

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.

Disbelief In Human Evolution Linked to Greater Prejudice and Racism

Biology
For centuries, human evolution and prejudice have been closely connected. Darwin’s theory of evolution suggested that humans are not only related through common descent,...

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.

Study: Evolution is now acknowledged by the majority of Americans

Biology
Highlights: - According to a recent University of Michigan study, 54% of Americans now accept the theory of evolution as the most plausible explanation for...
