Branching patterns are prevalent in our natural environment and the human body, such as in the lungs and kidneys. For example, specific genes that express growth factor proteins are known to influence the development of the lungs' complex branches. Researchers have unveiled a regulatory system linking signal, force, and shape in mouse lung structure development. The team recognized that the signal protein ERK plays an active role in causing growing lung tissue to curve ..read more

Researchers reveal how DNA gyrase resolves DNA entanglements. The findings not only provide novel insights into this fundamental biological mechanism but also have potential practical applications. Gyrases are biomedical targets for the treatment of bacterial infections and the similar human versions of the enzymes are targets for many anti-cancer drugs. Better understanding of how gyrases work at the molecular level can potentially improve clinical treatments ..read more

Most disease-causing bacteria are known for their speed: In mere minutes, they can double their population, quickly making a person sick. But just as dangerous as this rapid growth can be a bacterium's resting state, which helps the pathogen evade antibiotics and contributes to severe chronic infections in the lungs and blood, within wounds, and on the surfaces of medical devices. Now, scientists have discovered how long chains of molecules called polyphosphates (polyP) are needed for bacteria to slow down movements within cells and let them enter this resting state ..read more

Vitamin B1 is an essential micronutrient for human beings. Its deficiency is the cause of numerous diseases of the nervous and cardiovascular systems. Researchers have achieved a significant advance in the fight against vitamin B1 deficiency, frequently associated with a rice-based diet. By specifically targeting the nourishing tissues of the rice grain, the scientists have succeeded in considerably increasing its vitamin B1 content, without compromising agronomic yield. These results could help solve a major public health problem in regions where rice is the staple food ..read more
