Gene responsible for lutein esterification in bread wheat identified

Researchers have identified and confirmed the gene responsible for lutein esterification in bread wheat. The activity of this gene controls the timing of esterification in grain, which is related to storage and nutritional qualities of bread wheat and other grains.

For the first time, professor observes crystallized iron product, hemozoin, made in mammals

For the first time ever, a professor has observed a crystallized iron product called hemozoin being made in mammals, with widespread implications for future research and treatment of blood disorders. Findings could be used to treat sickle cell disease and malaria patients, while opening up diverse research avenues across immunology, parasitology, neuroscience, microbiology, and even urology.

Cracking how tardigrades survive the extremes

Scientists have gained a new understanding of how tiny, ultra-resilient invertebrates known as tardigrades, or 'water bears,' are protected in extreme conditions. Tardigrades are found in water environments around the world — including mountainous, deep sea and Antarctic environments. The researchers discovered that a tardigrade protein named Dsup binds to chromatin — DNA inside cells — and forms a protective cloud against extreme survival threats such as radiation damage.

New biofabrication method creates one scaffold to guide regeneration of multiple tissues

Scientists have taken a major step to address the challenge of engineer tissues organized like native tissues. They have demonstrated a new method to fabricate scaffolds presenting spatially organized cues to control cell behavior locally within one material.

Adult fly intestine could help understand intestinal regeneration

Intestinal epithelial cells (IECs) are exposed to diverse types of environmental stresses such as bacteria and toxins, but the mechanisms by which epithelial cells sense stress are not well understood. New research has found that Nox-ROS-ASK1-MKK3-p38 signaling in IECs integrates various stresses to facilitate intestinal regeneration.

Engineered protein crystals make cells magnetic

If scientists could give living cells magnetic properties, they could perhaps manipulate cellular activities with external magnetic fields. But previous attempts to magnetize cells by producing iron-containing proteins inside them have resulted in only weak magnetic forces. Now, researchers have engineered genetically encoded protein crystals that can generate magnetic forces many times stronger than those already reported.
