For brain hemorrhage, risk of death is lower at high-volume hospitals

For patients with a severe type of stroke called subarachnoid hemorrhage, treatment at a hospital that treats a high volume of subarachnoid hemorrhage cases is associated with a lower risk of death, reports a study in the November issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. —> Read More Here

China launched a robotic mission to the Moon today (Oct. 23 EDT/Oct. 24 BJT) that will test a slew of key technologies required for safely delivering samples gathered from the Moon’s surface and returning them to Earth later this decade for analysis by researchers.

Today’s unmanned launch of what has been dubbed “Chang’e-5 T1” is a technology testbed serving as a precursor for China’s planned (…)

Research Ethics and Ebola

Every day we learn of new suspected cases of Ebola infection in the United States, causing worries among the population and renewed efforts by the Centers for Disease Control and Prevention to contain the epidemic.

A student in the postgraduate course in research ethics that I teach at Einstein recently asked whether we could discuss the Ebola epidemic in class. Because I had prepared the syllabus for the course months ago, I hadn’t thought of including a discussion of ethics in research on Ebola. But the time was ripe, and I gratefully accepted the student’s suggestion.

A letter published online in the Lancet on Oct. 10 is titled “Randomised Controlled Trials for Ebola: Practical and Ethical Issues.” The authors are a distinguished group of scientists, ethicists and physicians from all over the world, including several from West Africa, where the epidemic is raging. The letter makes an urgent plea for embarking on research for experimental treatments that would not randomize patients to a control arm that provides only conventional care or conventional care along with a placebo.

Departing From the Randomized Clinical Trial

Instead, the letter argues, “When conventional care means such a high probability of death, it —> Read More Here

Beautiful Images of the October 23, 2014 Partial Solar Eclipse

“The Sun looks like it has a bite taken out of it!” said one enthusiastic viewer of the partial solar eclipse on October 23. Although I only had my paper plate pinhole projector that I shared with a crowd of folks (you can see an image of it near the bottom of the images here), the funny-looking Sun projected onto the plate definitely looked like a cookie with bite out of it or a clipped fingernail. But thankfully, as the Moon moved in front of the Sun today, legions of astrophotographers were out to take fantastic images of the eclipse. And the gigantic sunspot named AR 2192 made a cameo appearance as well. Enjoy the gallery below!

Thanks to everyone who uploaded images to our Flickr page or shared their images on Twitter.
