New microscopes reveal live, developing cells in unprecedented 3-D clarity Posted: 25 Oct 2013 09:30 AM PDT Researchers have developed two new microscopes, both the first of their kind. The first captures small, fast moving organisms at an unprecedented rate and the second displays large cell samples in three dimensions while decreasing the amount of harmful light exposure to the cells. Both microscopes surpass in clarity any other currently on the market.

Social service barriers delay care among women with abnormal cancer screening Posted: 25 Oct 2013 08:39 AM PDT A recent study has found that women with multiple barriers to healthcare, especially those with social barriers such as problems with housing and income, experienced delays in cancer screening follow up compared to those with fewer barriers or no social barriers.

Green algae move to the beat: Flagellar synchronization of swimming algae explained Posted: 25 Oct 2013 08:38 AM PDT Researchers explain the flagellar synchronization of swimming algae. The beating of flagella is one of the basic principles of movement in the cellular cosmos. However, up to now, scientists were unsure as to how the movements of several of these small cellular appendages are synchronized.

A cost-effective way toward personalized cancer drugs Posted: 25 Oct 2013 07:22 AM PDT Before a cancer patient embarks on a course of treatment, tests can be carried out to establish whether or not the chosen cytostatic agent combination is likely to be effective. But the time-consuming and expensive nature of traditional testing methods is prohibiting their widespread use. Researchers have developed a cost-effective, automated system that allows doctors to determine which medications will prove most benefit for each patient.

Experimental drug reduces brain damage, eliminates brain hemorrhaging in rodents afflicted by stroke Posted: 25 Oct 2013 06:19 AM PDT The experimental drug 3K3A-APC shows promise as a stand-alone therapy for stroke or in combination with the FDA-approved clot-busting drug therapy tPA (tissue plasminogen activator).

Genetic variants associated with bronchodilator responsiveness Posted: 25 Oct 2013 06:19 AM PDT A new study reveals several new gene variants that are associated with how people living with chronic obstructive pulmonary disease respond to inhaled bronchodilators.

Portable vision screening devices accurately identify vision problems in young children Posted: 25 Oct 2013 06:19 AM PDT Portable screening devices allow pediatricians to successfully screen children for vision problems, including amblyopia.
