Breast Cancer Etiology May Vary By Subtype Posted: 30 May 2009 08:00 AM PDT Women's reproductive and lifestyle characteristics can be linked to different invasive breast cancer subtypes. Data on 2,544 breast cancer cases suggests that traditional risk factors for development of the condition are associated with different kinds of tumor.

Picosecond Oscilloscope Posted: 30 May 2009 08:00 AM PDT An oscilloscope is a device for displaying signals that are too fast to be seen by the human eye. Typically the signal consists of a voltage level that changes quickly moment by moment (over millisecond to nanosecond timescales). What is seen on the screen of the scope is a waveform whose value is graphed along the vertical axis as a function of the horizontal axis representing time. An electron beam, aimed at a phosphorescent screen, is swept horizontally providing a light-trace on the screen while, coincidentally, the instantaneous voltage of the input signal is used to deflect the electron beam up or down, creating the visible trace.

Effectively Managing Pain With Depression Posted: 30 May 2009 08:00 AM PDT Closely monitored antidepressant therapy coupled with pain self-management can produce substantial improvements in both depression and pain, according to new research.

Blue Whale Discovered Singing In New York Coastal Waters Posted: 30 May 2009 02:00 AM PDT For the very first time in New York coastal waters, the voices of singing blue whales have been positively identified. Acoustic experts confirmed that the voice of a singing blue whale was tracked about 70 miles off of Long Island and New York City on Jan. 10-11, 2009, as the whale swam slowly from east to west. At the same time, a second blue whale was heard singing offshore in the far distance.

New Glucose-regulating Protein Linked With Diabetes Posted: 30 May 2009 02:00 AM PDT Researchers have linked a specialized protein in human muscles to the process that clears glucose out of the bloodstream, shedding light on what goes wrong in type 2 diabetes on a cellular level.

Dental Researchers ID New Target In Fight Against Osteoporosis, Periodontitis Posted: 30 May 2009 02:00 AM PDT Researchers have identified a promising new target in the fight against osteoporosis and periodontitis: inhibiting the activity of the NF-kB protein restores a healthy balance between bone formation and resorption. The findings could offer new hope to the millions of people who struggle with osteoporosis and periodontitis each year.

Getting More From Whole-transcript Microarrays Posted: 30 May 2009 02:00 AM PDT Women's reproductive and lifestyle characteristics can be linked to different invasive breast cancer subtypes. Data on 2544 breast cancer cases suggests that traditional risk factors for development of the condition are associated with different kinds of tumor.

Evolution Of Gene Regulation: How Microbial Neighbors Settle Differences Posted: 30 May 2009 02:00 AM PDT Supply and demand could be a governing principle even at the genetic level, because most genes are only expressed when needed. New results show that, in microbes, evolutionary factors determine which regulation mechanism will regulate a given gene.

Evolution Of Migraine: From Episodic Headache To Chronic Disorder Posted: 30 May 2009 02:00 AM PDT Patients living with migraine have strong reason for new optimism concerning a positive future. Two review articles and an accompanying editorial, "The Future of Migraine: Beyond Just Another Pill," in the current issue of Mayo Clinic Proceedings, are the basis for an ironic premise.

Ghost Remains After Black Hole Eruption Posted: 29 May 2009 05:00 PM PDT NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole.
