VIDEO: The war is on to replace warfarin

Earlier this month, the European Medicines Agency approved Boehringer Ingelheim’s blood-thinner drug Pradaxa (dabigatran) as a stroke prevention treatment in people with a cardiac arrhythmia condition known as atrial fibrillation. The clot-prevention agent, which gained US approval last October, is the first replacement to the anticoagulation standby warfarin to be green-lighted for this disease in 50 years — but it’s probably not the last.  Read more

VIDEO: Björk’s infectious new tune comes as an educational biology app

It’s not every day you hear a song inspired by infection. But, then again, not many musical artists are like Iceland’s Björk. Last week, the singer and multi-instrumentalist released the song “Virus” off of her forthcoming album, Biophilia, due out on 27 September. But she didn’t release the tune as a standard digital download; instead, the song takes the form of an interactive app.  Read more

VIDEO: Electronic skin monitors body vitals

VIDEO: Electronic skin monitors body vitals

In the past few years we’ve watched most of our electronics shrink and go wireless — that is, except our electrophysiological sensors. Doctors still track heart rate by gluing electrodes attached to wires to our skin, a technology that has changed little since its introduction in the 1970s. But research published today in Science presents a new kind of tiny sensor — and the beauty is that it’s only skin-deep.  Read more

VIDEO: Animal study supports use of bear bile-mimicking compound for treatment of fetal heart arrhythmias

One of my general “rules for living a healthy life” is to stay as far away from bears as possible — not to mention their bile. But many mainstream doctors disagree and use a synthetic version of a bear bile component, ursodeoxycholic acid (UDCA), to treat heart attacks, liver disorders and gallstones. A new rat study published today in Hepatology adds to this list; it offers insight into how the synthetic form of UDCA can slow the flow of electricity within fetal hearts, presenting a potential treatment for arrhythmia.  Read more

VIDEO: New gene linked to ADHD

Korean scientists have identified a connection between attention deficit hyperactivity disorder (ADHD) and a small error in a specific gene. The discovery, published online this week in Nature Medicine, could pave the way for new drugs to treat ADHD, a condition that affects an estimated 5% of school-aged children, making it hard for them to learn.  Read more

VIDEO: You don’t get to 11 million papers without a few dodgy results

You may be more familiar with Mark Zuckerberg than David Lipman. But Lipman — who has directed the US National Center for Biotechnology Information in Bethesda, Maryland for the past 22 years — may have had a more revolutionary impact than the Facebook founder on the way scientists interact by creating the ultimate network for biomedical research: PubMed.  Read more

Liz Taylor: activist, actress and clinical trial subject

Elizabeth Taylor was many things to many people: a screen legend, a social activist, a fashion icon and so much more. But to Abbott Laboratories, the Chicago-based pharmaceutical company, Taylor was also one of nearly 300 study subjects enrolled in the Endovascular Valve Edge-to-Edge REpair Study (EVEREST II), a clinical trial testing an experimental medical device called MitraClip.  Read more
