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...

In a new study, researchers have discovered how the protein PP2A can inhibit tumor growth in mice. The protein turns off an enzyme that stimulates cell growth, thus inhibiting the development of cancer.

Proteins are found throughout our cells and regulate a lot of biological processes that are important forour survival. But some of them also regulate processes that can make us sick. Now, an international research team, with researchers from the University of Copenhagen at the forefront, has achieved a much better understanding of one such protein.

In a new study, the researchers discovered how the protei...
