Siberian hamsters show what helps make seasonal clocks tick

Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping mechanisms ...

Genetic code used to engineer a living protein

Yale University researchers have successfully re-engineered the protein-making machinery in bacteria, a technical tour de force that promises to revolutionize the study and treatment of a variety of diseases.

The dual face of photoreceptors during seed germination

Seed germination depends on light in many plants. But not always: Aethionema arabicum, a plant adapted to challenging environmental conditions, does it its own way. Here, the phytochromes, the receptors for red and far-red ...

Hyaluronic acid research could spur new therapeutics

For more than two decades, scientists have puzzled over how vertebrates make the essential polysaccharide hyaluronic acid, which has broad medical applications. One team took a different tack and solved the mystery.

Microscopy opens doors for studying neurological diseases

The intricate functions of cellular processes have mystified scientists for decades. But with the help of tools like cryogenic electron microscopy (Cryo-EM), researchers at Penn State College of Medicine are starting to see ...

The 'airbag' that protects cells against stress

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have identified the molecular mechanisms that allow cells to survive mechanical stress. The results, published today in Nature Communications, show ...
