Biologists at Memorial Sloan-Kettering Cancer Center identified a set of genes working together to remodel blood vessels and promote breast cancer spread to the lungs. Targeting these genes with drug combinations may prove useful in treating metastatic breast cancer.
Researchers at MIT have developed a humanoid robot called Domo that can adapt to new environments, grasp objects, and interact with humans. The robot learns from its experiences and can perform tasks like putting away dishes, which could help elderly or wheelchair-bound people.
Over a dozen countries have adopted national indoor smoke-free policies, including Ireland and New Zealand, making progress in protecting people from second-hand smoke. The World Health Organization Framework Convention on Tobacco Control has helped galvanize global commitment to clean-air policies and tobacco control initiatives.
A Princeton University research team studied the damage caused by Hurricane Katrina and the Indian Ocean Tsunami of 2004, discovering that hurricanes and tsunamis can inflict similar forces on structures. The team's findings suggest that storm surges, in particular, can cause significant damage to buildings and bridges.
A study found that a generic drug called prazosin improves sleep quality and reduces trauma nightmares in veterans with posttraumatic stress disorder (PTSD). The drug, already used for high blood pressure and prostate problems, was shown to improve overall well-being and functioning.
Engineers at UC San Diego's Jacobs School of Engineering used a virtual building to test the impact of the 1994 Northridge earthquake on a 275-ton structure. The virtual model allowed researchers to visualize data from over 600 sensors, gaining new insights into structure performance and enabling 'what if' simulations.
