Hyundai’s Genesis unveils the Mint, its vision for a teeny electric luxury car. The concept vehicle is designed to be a “city car” that can squeeze through the narrow alleys and dense traffic of packed urban centers. https://cnn.it/2GrFSDv
A woman has regained full consciousness after 28 years in a vegetative state. Munira Abdulla suffered a severe brain injury a car crash in the United Arab Emirates (UAE) in 1991 – when she was 32. “I never gave up on her because I always had a feeling that one day she will wake up,” her son Omar Webair.
Scientists said Tuesday they might have detected the first known seismic tremor on Mars in a discovery that could shed light on the ancient origins of Earth’s neighbour.
A dome-shaped probe known as SEIS landed on the surface of Mars in December after hitching a ride on NASA’s InSight spacecraft.

Keith Comito, interviewed by Adam Ford at the Undoing Aging 2019 conference in Berlin, discusses why solving the diseases of old age is a powerful cause.
How can solving aging reduce suffering? What are some common objections to the ideas of solving aging? How does Anti-Aging stack up against other cause…
Scientists at the University of Bristol have invented a new technology that could lead to the development of a new generation of smart surgical glues and dressings for chronic wounds. The new method, pioneered by Dr. Adam Perriman and colleagues, involves re-engineering the membranes of stem cells to effectively ‘weld’ the cells together.
Cell membrane re-engineering is emerging as a powerful tool for the development of next generation cell therapies, as it allows scientists to provide additional functions in the therapeutic cells, such as homing, adhesion or hypoxia (low oxygen) resistance. At the moment, there are few examples where the cell membrane is re-engineered to display active enzymes that drive extracellular matrix production, which is an essential process in wound healing.
In this research, published in Nature Communications today, the team modified the membrane of human mesenchymal stem cells (hMSCs) with an enzyme, known as thrombin, which is involved in the wound healing process. When the modified cells were placed in a solution containing the blood protein fibrinogen, they automatically welded together through the growth of a natural hydrogel from the surface of the cells. The researchers have also shown that the resulting 3D cellular structures could be used for tissue engineering.
