MIT's new nanoparticle carries three cancer-fighting drug molecules — doxorubicin is red, ...

Delivering drugs that can knock out tumor cells within the body, without causing adverse side effects, is a tricky busines. It's why scientists have taken to engineering new and creative types of nanoparticles that do the job. Increasing a nanoparticle's ability to carry more drugs expands treatment options, but creating nanoparticles capable of delivering more than one or two drugs has proven difficult – until now. Scientists at MIT report creating a revolutionary building block technique that's enabled them to load a nanoparticle with three drugs. The approach, they say, could be expanded to allow a nanoparticle to carry hundreds more.  Read More

Stem cells are highly promising for the treatment of everything from HIV to leukemia to baldness. In many cases, however, a great number of them must be used in order have a noticeable effect, which makes treatments impractical or expensive. Now, scientists at Harvard-affiliated Brigham and Women's Hospital have found that a smaller number of stem cells can still get the job done, if they're first hopped up on steroids.  Read More

The cloud-based supercomputer will be used to suggest patient specific cancer treatments f...

IBM's Watson supercomputer is being re-tasked to help clinicians create personalized treatments for a common form of brain cancer known as glioblastoma. The project, which is a collaboration between IBM and the New York Genome Center (NYGC), hopes to make use of Watson's artificial intelligence to analyze vast quantities of data in order to suggest a personalized life-saving treatment based on the patient's individual case.  Read More

New research suggests a nasal spray could be used to treat depression  (Photo: Shutterstoc...

A nasal spray containing a specially-developed protein peptide could form the basis for highly-targeted treatment for depression, new research from the Centre for Addiction and Mental Health (CAMH) has shown. The peptide, when delivered in spray from, was found to relieve symptoms of depression, with the lead researcher hopeful of little to no side-effects.  Read More

The Cefaly headband is claimed to not only treat migraines, but help to reduce their frequ...

Though using electrical stimulation of the brain as a means of treating migraines has provided an alternative to over-the-counter medication, the administering of the electrical currents can be complex, involving bulky equipment or even surgically implanted electrodes. Cefaly, a battery-operated headband, has now been approved by FDA (US Food and Drug Administration) and is said to not only treat migraines, but possibly prevent them altogether.  Read More

The Vector Gait and Safety System uses a track-mounted robotic trolley to keep patients fr...

When a patient is undergoing rehab for a condition that compromises their gait or sense of balance, the process certainly isn't helped by the constant worry that they might fall. In fact, even the caregivers themselves can be injured when trying to move patients around. That's why California-based rehabilitative tech firm Bioness developed its Vector Gait and Safety System. It involves suspending the patient below a robotic trolley, that moves with them to hold them up.  Read More

Electrical contacts located in the fingertips deliver short electrical pulses, stimulating...

While we can counter the deterioration of sight and hearing with glasses and hearing aids, few tools exist for combating a degenerating sense of touch. A common ailment among stroke patients and the aging, treating diminishing tactile perception has proven a complicated task. Looking to provide a wearable solution unimposing enough for everyday use, a research team from Germany's Ruhr University Bochum (RUB) is developing a stimulation glove designed to be worn passively to alleviate such impairments.  Read More

A close look at one of the nanomotors (inset), inside a living human cell

Imagine if it were possible to send tiny machines into living cells, where they could deliver medication, perform ultra-micro surgery, or even destroy the cell if needed. Well, we've recently come a little closer to being able to do so. Scientists at Pennsylvania State University have successfully inserted "nanomotors" into human cells, then remotely controlled those motors within the cells.  Read More

RevMedx's XStat syringe injects hemostatic sponges into deep wounds to control hemorrhage ...

Uncontrolled hemorrhage (bleeding out) is responsible for 80 percent of combat deaths. About the same proportion of those who die after being evacuated to a medical treatment facility also die of hemorrhage, usually associated with deep arterial wounds that cannot be treated using tourniquets – people die because we can't plug a simple hole. Now RevMedX, a small Oregon startup, has developed an alternative approach to treat such potentially survivable injuries.  Read More

A nanoparticle delivery mechanism (left) treats tumors in mice more effectively

A common strategy for treating tumors is combining two or more drugs, which has the effect of decreasing toxicity and increasing the synergistic effects between the drugs. However, the efficacy of this kind of cocktail treatment suffers when the drugs require access to different parts of the cell, a bit like fighting a battle by depositing all your archers on the same spot as your infantrymen. By making use of nanoparticle-based carriers, researchers at North Carolina State University are able to transport multiple drugs into cancerous cells optimally and precisely, in maneuvers that any field commander would be proud of.  Read More
