In a major breakthrough for regenerative medicine, scientists have partially restored vision in a blind man using an emerging technique called optogenetics. The approach involved injecting the patient’s eye with genes that code for light-sensitive proteins found in green algae, and represents the first successful clinical application of the technology, which enabled the patient to locate and identify objects for the first time in decades.
The continuing miniaturization of electronics is opening up some exciting possibilities when it comes to what we might place in our bodies to monitor and improve our health. Engineers at Columbia University have demonstrated an extreme version of this technology, developing the smallest single-chip system ever created, which could be implanted with a hypodermic needle to measure temperature inside the body, and possibly much more.
By turning modern scientific tools on an antibiotic discovered 70 years ago, researchers have unearthed a previously unknown mechanism it uses to pierce and pop superbugs like balloons. Promisingly, the scientists have also demonstrated how this approach to taking out bacteria can be supercharged by combining it with other antibiotics, potentially offering a new form of defense against deadly, drug-resistant bacteria.
The accumulation of plaque inside the arteries can be an insidious condition with grave consequences that include blood clots and strokes, but luckily it does give off some tell-tale signs. Researchers in the UK have developed a new type of glowing probe that focuses on one of them, increasing its fluorescence in the presence of a key enzyme and possibly acting as an early warning sign for cardiovascular disease.
A fascinating new study from a team of US researchers has used machine learning techniques to develop algorithms that can analyze naturalistic driving data and detect mild cognitive impairment and dementia in a driver. The work is still in the preliminary stages, however, the researchers claim it could be possible in the future to detect early signs of dementia using either a smartphone app or devices incorporated into car software systems.

The COVID-19 vaccination is front and center on most American’s minds as they decide whether or not to get it.
But it’s not just the vaccine itself. It’s not even whether the various vaccines are safe – and they appear to be for the vast majority of the population.
