People with irregular and abnormally fast heart rates caused by a condition called atrial fibrillation could be at a greater risk of stroke and bleeding because they are not receiving optimal treatment, warn scientists from UCL and The University of Hong Kong (HKU).

Social isolation and depression have become commonplace in older adults, with estimates suggesting almost 5 percent of adults aged 50 and above lived with major depression in 2015. What if you could address the problem through communication technology?

Researchers have developed a model that predicts which of the viruses that can jump from animals to people can also be transmitted from person to person—and are therefore possible sources of human diseases.

Anticipatory timing is controlled by two clocks in the brain, one dependent on memories from past experiences and the other on rhythm. Both are critical to our ability to navigate and enjoy the world. New research shows the neural networks supporting each of these timekeepers are split between two different parts of the brain, depending on the task at hand.

New observations of a young gas giant demonstrate the power of a ground-based method for searching for signatures of life.

A portable and affordable mobile diagnostic tool detects HIV viruses and monitors its management in resource-limited regions, utilizing a cellphone and nanotechnology.

Melanoma skin cancer tumors grow larger and are more likely to metastasize due to interactions between a pair of molecules, according to experiments in mice and human cells. The results may restore the potential for a type of cancer therapy previously abandoned in clinical trials.

Long-lived yelloweye rockfish have difficulty detoxifying mercury, which accumulates over time, within sensitive liver cells.

A new method of selectively binding proteins to nanoparticles has been published. The nanoparticles automatically recognize specific peptides, i.e. small proteins, and enter into highly selective binding with them. Among the model peptides which the researchers examined were amyloids. The researchers hope that the mechanism they have discovered might provide a new approach to treating diseases in which such deposits occur, such as Alzheimer’s disease.

Infectious Staphylococcus aureus diverts to its advantage a structure set up by human cells, in order to destroy and invade.
