New tools reveal how genes work and cells organize      (via sciencedaily.com)     Original source 

Researchers have discovered how certain proteins can attach to special structures in RNA, called G-quadruplexes. Additionally, they have developed computational tools capable of predicting these protein-RNA interactions. The newfound ability to predict these interactions can help future work in understanding molecular pathways in the cell and pave the way for developing drugs targeting these RNA G-quadruplex binding proteins, that are found to be involved in disease such as cancer.

First view of centromere variation and evolution      (via sciencedaily.com)     Original source 

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication by assuring faithful transmision of genetic materials when cells divide, the complexity of their genomic organization had been almost impossible to study. The lack of centromere sequences hindered exploration of how these regions help maintain genetic integrity. Now, advanced technologies have shown scientists how greatly centromeres differ in size and structure.

Researchers discover key gene for toxic alkaloid in barley      (via sciencedaily.com)     Original source 

Barley is one of the most important cereal crops on a global scale. Many barley cultivars produce a toxic alkaloid called gramine that affects the suitability of barley as fodder, but also helps to protect barley from pathogens. So far, the potential of manipulating gramine levels has not been harnessed for plant breeding, because the genetic basis of gramine production has been unresolved. Research groups now disclose the complete biosynthetic pathway of gramine and demonstrate how gramine biosynthesis can be introduced into model organisms or removed from barley.

Connecting the dots to shape growth forces      (via sciencedaily.com)     Original source 

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.

Long-period oscillations control the Sun's differential rotation      (via sciencedaily.com)     Original source 

The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations discovered in 2021 play a crucial role in controlling the Sun's rotational pattern. The long-period oscillations are analogous to the baroclinically unstable waves in Earth's atmosphere that shape the weather. In the Sun, these oscillations carry heat from the slightly hotter poles to the slightly cooler equator.

Natural recycling at the origin of life      (via sciencedaily.com)     Original source 

How was complex life able to develop on the inhospitable early Earth? At the beginning there must have been ribonucleic acid (RNA) to carry the first genetic information. To build up complexity in their sequences, these biomolecules need to release water. On the early Earth, which was largely covered in seawater, that was not so easy to do.

Signs of life would be detectable in single ice grain emitted from extraterrestrial moons      (via sciencedaily.com)     Original source 

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.
