A new type of test that uses complex sugars to detect prostate cancer earlier and with greater accuracy is being developed by researchers at the University of Birmingham. The test works by identifying sugars, known as glycans, in blood. These sugars are attached to protein molecules called PSA and are known to undergo distinct but subtle changes when cancer is present in the body.

Particular types of glycans are associated with different cancers – but until now, there has been no technology available to detect the glycans in an accurate, timely and sufficiently specific way.

Research led by a team in the University of Birmingham’s School of Chemical Engineering, has now developed a technique that can identify glycans associated with cancer with unprecedented accuracy...

Fitness tracker bracelets and watches provide useful information, such as step count and heart rate, but they usually can’t provide more detailed data about the wearer’s health. Now, researchers reporting in ACS Applied Materials & Interfaces have developed smart electronic glasses (e-glasses) that not only monitor a person’s brain waves and body movements, but also can function as sunglasses and allow users to control a video game with eye motions.

Devices that measure electrical signals from the brain (electroencephalogram; EEG) or eyes (e...

As inevitable fellow travellers on the bodies of astronauts, spaceships, or equipment, terrestrial microorganisms will undoubtedly come into contact with extraterrestrial environments. Researchers from the Radboudumc describe in an article in Astrobiology that bacteria can survive on an ‘extraterrestrial diet’, which affected their pathogenic potential.

No matter how well astronauts and material are decontaminated, co-travelling microorganisms into space cannot be prevented. Given the enormous adaptability potential of bacteria, it is conceivable that they will sometimes survive space travel and be able to settle in an extraterrestrial environment.

For this study, four non-fastidious environment-derived bacterial species with pathogenic features were selected, including Klebsiel...

The normal functioning of our hearts is maintained by our body’s control center—the brain—via an intricate network of nerves. When this communication is disrupted, it results in heart disease, including heart attacks, sudden cardiac death and problems in blood supply. As an added layer of safety, the heart has its own ‘little brain’, called the intracardiac nervous system (ICN) to monitor and correct any local disturbances in communication. The ICN is essential in supporting heart health and can even protect cardiac muscle during a heart attack...
