Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

Medical implants are widely being used in orthopaedics and in modern dentistry. While significant progress has been made to improve the production of implants using the most advanced materials and technologies, there is still need for additional strategies to improve and accelerate osseointegration. The improper integration of the implant material in the living bone can impair the healing process and limit the freedom of movement thereby rendering the implant useless.
The invention provides a multilayer bio-nanocoating
to improve significantly the adhesion of osteoblasts to the implant, which is shown in Fig.2. The applied bio-nano-coating is tightly connected to the implant and at the same time ensures flexibility of the molecular layers. Further the bio-nano-coating enables the native
conformation of embedded molecules, e.g. of fibronectin. Data from animal models are available for dental applications.
In summary, the invention comprises medicinal
implants with biofunctional coating, which will greatly reduce the incidence of periimplantitis and other complications related to the insufficient adhesion of the tissue to the implant.
