Neanderthal Genes are Responsible for Certain Traits in Modern Humans

Recent scientific discoveries have shown that Neanderthal genes comprise some 1 to 4% of the genome of present-day humans whose ancestors migrated out of Africa, but the question remained open on how much those genes are still actively influencing human traits -; until now.

Study Reveals Mechanisms Behind Swallowing in Detail

Sensory cells in the vagus nerve can detect and locate food in the esophagus. Their signals help transport the food onward to the stomach. Signal failure leads to swallowing disorders, say a team led by Carmen Birchmeier at the Max Delbrück Center.

Key Event that Controls the Timing of the Biological Clock Identified

Molecular clocks in our cells synchronize our bodies with the cycle of night and day, cue us for sleep and waking, and drive daily cycles in virtually every aspect of our physiology. Scientists studying the molecular mechanisms of our biological clocks have now identified a key event that controls the timing of the clock.

Stimulating Cell DNA Repair Processes to Combat the Root Cause of Autism Spectrum Disorders

A new treatment option has been discovered for fragile X syndrome, which is the most common genetic cause of autism spectrum disorders and is defined by a hereditary repetition of certain nucleotides in the DNA sequence of the FMR1 gene. Researchers at Massachusetts General Hospital (MGH) carried out the study, which was published in the journal Cell.
