Page 2: Research news on Biomolecules

Biomolecules, as physical systems, are distinct molecular entities synthesized or utilized by living organisms that exhibit specific structural, thermodynamic, and dynamical properties enabling biological function. They include nucleic acids, proteins, lipids, carbohydrates, and diverse metabolites, each characterized by defined covalent connectivity, three-dimensional conformations, and interaction potentials with solvents, ions, and other biomolecules. Their behavior is governed by quantum-mechanical bonding, classical electrostatics, and statistical thermodynamics, leading to emergent phenomena such as self-assembly, allostery, enzyme catalysis, and molecular recognition. In physical systems research, biomolecules are studied through techniques like spectroscopy, crystallography, cryo-EM, and molecular simulations to elucidate structure–function relationships and energy landscapes.

New formulation helps RNA vaccines withstand high temperatures

RNA vaccines, which have proved effective against COVID-19, are now being developed for many other diseases, including cancer. One drawback is that they require ultracold storage, but MIT researchers have found a promising ...

Natural proteins can guide active ingredients to diseased cells

After taking a pill, the drugs it contains are distributed throughout the body, reaching the tissues and cells affected by disease and performing their intended function. However, they also enter healthy cells, where they ...

Previously overlooked protein helps cells divide correctly

Modern technologies have made it possible to uncover a growing "hidden proteome"—proteins encoded by parts of the genome that researchers previously overlooked. Advances in sequencing and protein analysis are making it possible ...

Modification of magnetic nanoparticles improves RNA isolation

The COVID-19 pandemic clearly demonstrated the importance of rapid and reliable diagnostic methods for detecting and monitoring infectious diseases. Nucleic acids, including RNA, are key biomarkers used in the detection, ...

How calcium channels in muscle cells open together

Every step we take begins with a burst of calcium inside our muscle cells, causing them to contract. To prepare for action, the cells keep calcium locked in an internal compartment, the sarcoplasmic reticulum. Studding its ...
