Combining nanotubes and antibodies for breast cancer 'search and destroy' missions Posted: 05 Dec 2009 02:00 AM PST Researchers have demonstrated how single-walled nanotubes can be used to detect and destroy an aggressive form of breast cancer. |
Exposure to secondhand cigarette smoke over a lifetime increased breast cancer risk later in life Posted: 05 Dec 2009 02:00 AM PST Exposure to secondhand smoke for a prolonged period of time and in high quantity may increase the risk of breast cancer, even in women who never smoked cigarettes themselves. |
Posted: 05 Dec 2009 02:00 AM PST Scientists have made major strides in solving a problem that has been plaguing chemists for many years: how best to break carbon-hydrogen bonds and then to create new bonds to join molecules together. This problem is of great interest to the pharmaceutical industry, which currently relies on a method to accomplish this feat that is relatively inefficient and sometimes difficult to perform. |
Dream-enacting behavior is common in healthy young adults Posted: 05 Dec 2009 02:00 AM PST Dream-enacting behaviors are common in healthy young adults, and the prevalence of specific behaviors differs between men and women. |
Learning by imagining: How mental imagery training aids perceptual learning Posted: 04 Dec 2009 05:00 PM PST Practice makes perfect. But imaginary practice? Scientists show that perceptual learning -- learning by repeated exposure to a stimulus -- can occur by mental imagery as much as by the real thing. The results suggest that thinking about something over and over again could actually be as good as doing it. |
Muscle cell infusion shown to strengthen sphincters in animals Posted: 04 Dec 2009 05:00 PM PST A new study shows that muscle cells grown in the lab can restore an intestine's ability to squeeze shut properly. The work, performed in dogs and rats, might ultimately help treat patients with conditions such as gastric reflux and fecal incontinence. |
Orphaned mountain gorilla babies return home to Congo National Park Posted: 04 Dec 2009 05:00 PM PST More than two years after being evacuated following the 2007 killings of their mothers, mountain gorilla babies Ndakasi and Ndeze have returned home to the Democratic Republic of Congo, moving into a new custom-built forest sanctuary. |
