Dynamic Light Scattering (DLS) is a technique classically used for measuring the size of particles typically in the sub-micron region, dispersed in a liquid. The sensitivity of some modern systems is such that it can also now be used to measure the size of macromolecules in solution.

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.

Researchers are developing third generation CAR-T immunotherapy treatments which aim to be more effective with less side effects than previous therapies.

Under the influence of longer-term climate change, crop growing conditions are becoming more extreme.

Watch our step-by-step IHC video protocol to learn how to develop your chromogenic staining with DAB reagent systems.

Can molecules help lead the war against cancer?

In this talk, Dr. Patrick Gunning describes the seemingly insurmountable challenges that a medicinal chemist and drug discovery team face in their efforts to identify new drug molecules.

Former Welsh rugby captain and testicular cancer survivor Matthew Rees urges men to "check their tackle."

In this imaginative talk, neuroengineer Sam Rodriques takes us on a thrilling tour of the next 100 years in neuroscience. He envisions strange (and sometimes frightening) innovations that may be the key to understanding and treating brain disease -- like lasers that drill tiny holes in our skulls and allow probes to study the electrical activity of our neurons.

Scientists from the University of Bristol, CNRS and Imophoron Ltd worked with the computer technology giant Oracle to develop a new kind of vaccine that needs no refrigeration. They used synthetic biology, cryo-electron microscopy and high-performance cloud computing to produce a candidate vaccine against the mosquito-borne chikungunya virus. Their findings could revolutionise the way vaccines are designed, developed and stored.

There are things you can do right now to help our climate--like investing in renewable energy. But today on Reactions, we're digging into a few of the weirdest climate change-combating ideas out there.
