A new protein spin labelling technique

Site-directed spin labelling (SDSL) used in combination with electron paramagnetic resonance (EPR) spectroscopy has been a tried and trusted technique for elucidating the structure, function and dynamics of proteins and protein ...

New hydrogels show promise in treating bone defects

Bioengineers and dentists from the UCLA School of Dentistry have developed a new hydrogel that is more porous and effective in promoting tissue repair and regeneration compared to hydrogels that are currently available. Once ...

Antacid helps tuberculosis bacteria to survive

In 2017, some 10 million people suffered from tuberculosis and 1.6 million died of the disease. One reason that infection with Mycobacterium tuberculosis is so difficult to treat is because the bacteria can hide inside immune ...

A substance found in brown coal can help combat viruses

Scientists from Russia have demonstrated a novel approach leveraging high-resolution mass spectrometry and chemoinformatics to identify biologically active molecular components of humic substances extracted from coal, and ...

Making microbes that transform greenhouse gases

Researchers at the University of South Florida are harnessing the power of human physiology to transform greenhouse gases into usable chemical compounds—a method that could help lessen industrial dependence on petroleum ...

Probiotic hydrogels heal gut wounds other bandages can't reach

External wounds such as skin cuts or abrasions can often be easily covered with a simple Band-Aid or a larger wound patch to protect them and facilitate their healing. When it comes to some internal surfaces like those of ...

New insights into the origin of life

A famous experiment in 1953 showed that amino acids, the building blocks of proteins, could have formed spontaneously under the atmospheric conditions of early Earth. However, just because molecules could form doesn't mean ...

Manufacture of light-activated proteins

A new strategy for designing light-sensitive proteins has been developed by researchers at Ruhr-Universität Bochum (RUB). Such proteins, also known as optogenetic tools, can be switched on and off through light impulses, ...
