A specially created odor delivery device, along with machine learning-based analysis of scalp-recorded electroencephalogram, has enabled researchers to see when and where odors are processed in the brain. The study found that odor information in the brain is unrelated to perception during the early stages of being processed, but when perception later occurred, unpleasant odors were processed more quickly than pleasant odors. Problems with odor perception can be an early symptom of neurodegenerative diseases, so uncovering more of the neural bases of odor perception could help towards better understanding of those diseases in future.

A gene that has been associated with severe learning disabilities in humans has been found to also play a vital role in cells' response to environmental stress, according to a new study. The gene, Rad6 has previously been associated with a set of symptoms called 'Nascimento Syndrome,' that include severe learning disabilities.

The understanding of the clustering and movement of microswimmers has a range of applications from human health to tackling ecological problems.

Researchers have created a drug-delivering gel could make it easier for children and adults who have trouble swallowing pills to take their medications.

Researchers have identified a previously unrecognized form of hormone therapy-resistant prostate cancer, as well as a set of molecules that drive its growth. This discovery opens the door to the development of therapies that treat this specific disease.
