Main Point:

Nerve endings on our fingertips have the same ability of performing complex neural computations as we can find in our brain. Read more…

Sequencing at Sea – performing real-time DNA sequencing in the middle of the Pacific Ocean

Main Point:

Scientists overcame equipment failure, space constraints and shark-infested waters to do real-time DNA sequencing in a remote field location.

Published in:

PeerJ

Study Further:

Daylight was breaking over the central Pacific and coffee brewing aboard the MY Hanse Explorer. Between sips, about a dozen scientists strategized for the day ahead. Some would don wetsuits and slip below the surface to collect water samples around the southern Line Islands’ numerous coral reefs. Others would tinker with the whirring gizmos and delicate machinery strewn throughout the 158-foot research vessel. All shared a single goal: Be the first research group to bring a DNA sequencer out into the field to do remote sequencing in real time. Against an ocean of odds, they succeeded.

This three-week, five-island expedition took place last year with a research crew including San Diego State University computer scientist Rob Edwards, biologist Forest Rohwer, postdoctoral scholar Andreas Haas and graduate student Yan Wei Lim. They were accompanied by several other researchers from the San Diego region and around the world. The researchers published an account of their trip and methods today in the journal PeerJ.

More information needed to determine the effectiveness of different types of decision aids for advanced care planning

Decision Aids (Credit: Anon)Main Point:

Decision aids are underutilized for advanced care planning and their effectiveness is not well documented.

Published in:

Annals of Internal Medicine

Study Further:

An advanced care plan is a directive that explains a patient’s goals and preferences for future care in the event of serious illness or injury. Currently, less than 50 percent of severely or terminally ill patients have an advance directive in their medical record and physicians are only about 65 percent accurate in predicting patient preferences for intensive care. Decision aids are intended to help patients consider options in health care so that they may develop an advanced care plan, but little is known about their effectiveness. Read more…

Safety lapses at government labs raise serious bioterror concerns

Gas Mask (Credit: User Surface Forces/Flickr)Main Points:

Recent safety lapses at the Centers for Disease Control (CDC) and National Institute of Health (NIH) facilities illustrate a new and grave bioterror threat: the risk for disease and death emanating from biocontainment laboratories themselves, according to a commentary being published in Annals of Internal Medicine.

Early menopausal hormone therapy shows no effect on atherosclerosis progression

Hormone therapy (Credit: Getty Images/Universal Images Group)Main Point:

Early initiation of menopausal hormone therapy (MHT) improves some markers of cardiovascular disease (CVD) but does not affect the progression of atherosclerosis.

Published in:

Annals of Internal Medicine

Study Further:

CVD is the leading cause of death in women and incidence increases after menopause. Research suggests that cardiovascular benefits of MHT may be limited to women who begin treatment at a younger age, closer to menopause, or both. Read more…
