Transcription factors may inadvertently lock in DNA mistakes

Transcription factor proteins are the light switches of the human genome. By binding to DNA, they help turn genes 'on' or 'off' and start the important process of copying DNA into an RNA template that acts as a blueprint ...

'Nature's antifreeze' provides formula for more durable concrete

Secrets to cementing the sustainability of our future infrastructure may come from nature, such as proteins that keep plants and animals from freezing in extremely cold conditions. CU Boulder researchers have discovered that ...

Untangling a key step in photosynthetic oxygen production

Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, an international collaboration between scientists ...

Researchers discover giant cavity in key tuberculosis molecule

Researchers from the Department of Energy's SLAC National Accelerator Laboratory have discovered a strange new feature of a protein that's thought to be important in the development of tuberculosis: The protein contains a ...

Capturing extreme close-ups of cellular gene expression

Scientists studying genetic transcription are gaining new insights into a process that is fundamental to all life. Transcription is the first step in gene expression, the process taking place within all living cells by which ...

Miniaturized version of ribosome found in microsporidia

A research team lead by MIMS/SciLifeLab research group leader Jonas Barandun, UmeƄ University, Sweden, uses cryo-electron microscopy to provide near atomic details of the smallest known eukaryotic cytoplasmic protein synthesis ...

We now know how insects and bacteria control ice

Contrary to what you may have been taught, water doesn't always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is ...
