Caught in the act: Images capture molecular motions in real time

Researchers have used ultra-high-speed X-ray pulses to make a high-resolution "movie" of a molecule undergoing structural motions. The research, published in Nature Chemistry, reveals the dynamics of the processes in unprecedented ...

Life could be evolving right now on nearest exoplanets

Excitement about exoplanets skyrocketed when rocky Earth-like planets were discovered orbiting in the habitable zone of some of our closest stars – until hopes for life were dashed by the high levels of radiation bombarding ...

How ice particles promote the formation of radicals

The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer in combination with ice particles, such as those found ...

Nanodiamonds as photocatalysts

Climate change is in full swing and will continue unabated as long as CO2 emissions continue. One possible solution is to return CO2 to the energy cycle: CO2 could be processed with water into methanol, a fuel that can be ...

A protein prevents plants from premature flowering

The induction of flowering is of major importance from an ecological and agronomic point of view. Timely and synchronous flowering is essential to optimize pollination and allow seed production and maturation under favorable ...

Research zooms in on enzyme that repairs DNA damage from UV rays

A research team at the Department of Energy's SLAC National Accelerator Laboratory is using the Linac Coherent Light Source (LCLS) to study an enzyme found in plants, bacteria and some animals that repairs DNA damage caused ...

How do the chemicals in sunscreen protect our skin from damage?

Not so long ago, people like my Aunt Muriel thought of sunburn as a necessary evil on the way to a "good base tan." She used to slather on the baby oil while using a large reflector to bake away. Aunt Muriel's mantra when ...
