Researchers have discovered a plant cell surface molecule that can halt cell proliferation by acting as both an 'on' and 'off' switch. The discovery sheds light on the complex process of G protein signaling and has implications for agriculture and potentially human diseases.
A NASA grant is supporting a two-year study at Florida Tech to develop algorithms that can learn from historical data and detect potential problems with a space shuttle component. The research aims to improve the efficiency of monitoring systems, reducing the time and effort required to extract knowledge from experts.
In a phase II clinical study, exemestane demonstrated a higher tumor response rate (41%) compared to tamoxifen (17%) in shrinking tumors. Exemestane was also well-tolerated with fewer side effects than tamoxifen.
Researchers have made significant progress in isolating skin stem cells, with the discovery that these cells can be found in the basal epidermis layer. This breakthrough has the potential to treat wounds, including burns, by transplanting stem cells directly onto the damaged area.
The AMPS system uses a tailored computer model, Polar MM5, to provide detailed forecasts for the extreme polar environment. Meteorologists have successfully used AMPS in emergency rescues from Antarctica since 2001, including a recent medical evacuation and ship rescue.
