Protein network dynamics during cell division      (via sciencedaily.com)     Original source 

An international team has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.

The enemy within: How pathogens spread unrecognized in the body      (via sciencedaily.com)     Original source 

Some pathogens hide inside human cells to enhance their survival. Researchers have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In their study, they reveal the crucial role of a bacterial nanomachine in this infection process.

Breakthrough rice bran nanoparticles show promise as affordable and targeted anticancer agent      (via sciencedaily.com)     Original source 

Plant-derived nanoparticles have demonstrated significant anticancer effects. Researchers recently developed rice bran-derived nanoparticles (rbNPs) that efficiently suppressed cell proliferation and induced programmed cell death of only cancer cells. Furthermore, rbNPs successfully suppressed the growth of tumors in mice having aggressive adenocarcinoma in their peritoneal cavity, without any adverse effects. Given their low production costs and high efficacy, rbNPs hold great promise for developing affordable and safe anticancer agents.

Key protein regulates immune response to viruses in mammal cells      (via sciencedaily.com)     Original source 

Researchers have revealed the regulatory mechanism of a specific protein, TRBP, that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders.

Light show in living cells      (via sciencedaily.com)     Original source 

Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.

Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?      (via sciencedaily.com)     Original source 

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.

RNA's hidden potential: New study unveils its role in early life and future bioengineering      (via sciencedaily.com)     Original source 

The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may have supported the activities of early life forms. Now, researchers explore how RNA elongation is regulated allosterically, shedding light on its impact on early life processes and offering insights into the fabrication of arbitrary RNA nanostructures with various modern applications.

No gamma rays seen coming from nearby supernova      (via sciencedaily.com)     Original source 

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce.

Most massive stellar black hole in our galaxy found      (via sciencedaily.com)     Original source 

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun.
