Defect in fruit fly respiratory system may provide insights into human aortic aneurysms      (via sciencedaily.com)     Original source 

A team of researchers has gained new insights into the respiratory system of fruit flies -- the so-called tracheal system -- which could be important for future research into aneurysms. Scientists carried out genetic, cell biological and biochemical studies on Drosophila embryos. They found that the cells in the fruit fly's tracheal system are connected to the extracellular matrix by the proteins Dumpy and Piopio.

Ancient sea monster remains reveal oldest mega-predatory pliosaur      (via sciencedaily.com)     Original source 

The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.

Moving muscle fibers with magnets 'programs' how they align within tissue      (via sciencedaily.com)     Original source 

Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to program muscle cell alignment, which is strongly tied to healthy muscle function.

How cord-like aggregates of bacteria lead to tuberculosis infections      (via sciencedaily.com)     Original source 

The ability of Mycobacterium tuberculosis (MTB), a serious respiratory infection, to form snake-like cords was first noted nearly 80 years ago. Investigators report the biophysical mechanisms by which these cords form and demonstrate how several generations of dividing bacteria hang together to create these structures that enable resistance to antibiotics.

Physical theory improves protein folding prediction      (via sciencedaily.com)     Original source 

Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers have developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes.

Researchers identify the oldest pieces of Baltic amber found on the Iberian Peninsula: imports began over 5,000 years ago      (via sciencedaily.com)     Original source 

Baltic amber is a luxury material used in jewellery and handicrafts all over the world. Researchers have shown that Baltic amber arrived on the Iberian Peninsula at least in the 4th millennium BC, more than a millennium earlier than previously thought.

Restoring the function of a human cell surface protein in yeast cells      (via sciencedaily.com)     Original source 

Yeast cells are widely used to study G protein-coupled receptors (GPCRs), a large group of cell surface proteins in humans. However, several of these proteins lose their function when introduced into yeast cells. To tackle this issue, researchers developed an innovative strategy to restore GPCR function in yeast cells by inducing random mutations. Their findings can help understand GPCRs better and could pave the way to therapeutic breakthroughs for many diseases.

Unlocking secrets of immune system proteins: A potential path to new treatments      (via sciencedaily.com)     Original source 

Using cryo-electron microscopy (cryo-EM), researchers captured unprecedented images of key immune system receptors interacting with messenger proteins, elucidating how the receptors change shape upon activation and transmit signals within the cell. The findings suggest new pathways for developing therapeutic molecules for diseases such as COVID-19, rheumatoid arthritis, neurodegenerative diseases and cancer.

Boosting weak immune system: Scientists find an unusual weapon against virus      (via sciencedaily.com)     Original source 

Infections with cytomegalovirus (CMV) are extremely common and often pose no major threat to the vast majority of people. They can however be deadly for people whose immune system is weakened, e.g., after bone marrow transplantation. Current treatments against CMV infections are very limited and can have severe side effects. Researchers now propose a new way to protect against CMV. Instead of targeting the virus, their approach boosts the weak immune system and lets it fight the virus on its own.

Study reveals our European ancestors ate seaweed and freshwater plants      (via sciencedaily.com)     Original source 

Researchers say they have found 'definitive' archaeological evidence that seaweeds and other local freshwater plants were eaten in the mesolithic, through the Neolithic transition to farming and into the Early Middle Ages, suggesting that these resources, now rarely eaten in Europe, only became marginal much more recently.

Fungal infection in the brain produces changes like those seen in Alzheimer's disease      (via sciencedaily.com)     Original source 

Researchers have discovered how the fungus Candida albicans enters the brain, activates two separate mechanisms in brain cells that promote its clearance, and, important for the understanding of Alzheimer's disease development, generates amyloid beta (Ab)-like peptides, toxic protein fragments from the amyloid precursor protein that are considered to be at the center of the development of Alzheimer's disease.
