Laser-produced uranium plasma evolves into more complex species

When energy is added to uranium under pressure, it creates a shock wave, and even a tiny sample will be vaporized like a small explosion. By using smaller, controlled explosions, physicists can test on a microscale in a safe ...

Structure of protein nanoturbine revealed

Cells rely on protein complexes known as ATP synthases or ATPases for their energy needs. Adenosine triphosphate (ATP) molecules power most of the processes sustaining life. Structural biologist Professor Leonid Sazanov and ...

Experiments illuminate key component of plants' immune systems

Plants, like humans and animals, have over millions of years evolved complex immune systems that fend off invading pathogens. But unlike many animals, plants lack adaptive immunity conferred by antibodies. This means each ...

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 ...

Catalytic transformation of ethylene

National University of Singapore chemists have developed a catalytic method using visible light for the difunctionalization of ethylene for potential use in the production of fine chemicals.

Entropy explains RNA diffusion rates in cells

Recent studies have revealed that within cells of both yeast and bacteria, the rates of diffusion of RNA proteins—complex molecules that convey important information throughout the cell—are distributed in characteristic ...

What can you do with two omes that you can't do with one?

What can you learn from two omes that you can't tell from one? You might determine how different bacterial strains in a water sample contribute specific functions to its overall microbiome. You might find that duplication ...
