When Jeff Siewerdsen, Ph.D., joined MD Anderson last year, he finally got the opportunity to work more closely with clinical teams to make advances that would benefit patients and clinicians in the operating room.

Learn more about the role of your stomach and learn more about the signs and symptoms of stomach cancer that you should be aware of.
The stomach is part of the body’s digestive system, located in the upper abdomen.
It acts as a temporary storage area for food before being mixed and broken down and passed through the rest of the upper gastrointestinal system.
Stomach cancer – sometimes also referred to as gastric cancer – occurs when abnormal cells in the stomach grow out of control. This may also occur in the junction where the stomach meets the oesophagus.
Brain scans of a 72-year-old man diagnosed with a highly aggressive form of cancer known as a glioblastoma have revealed a remarkable regression in his tumor’s size within days of receiving an infusion of an innovative new treatment.
Though the outcomes of two other participants with similar diagnoses were somewhat less positive, the case’s success still bodes well for the search for a way to effectively cure what is currently an incurable disease.
Glioblastomas are typically about as deadly as cancers can get. Emerging from supporting cells inside the central nervous system, they can rapidly develop into malignant masses that claim up to 95 percent of patient lives within five years.
Medical implants such as pacemakers and gastric stimulators have improved our lives, but the batteries in these devices eventually run out and require surgery to replace them.
It raises a futuristic question: what if there was a way to avoid cutting a patient’s body open to replace a battery?
A team of Chinese scientists have come up with a possible method to pull that off by developing an implantable battery that uses oxygen already inside the human body to continuously power itself up.
Scientists have identified a new method of analysing genomic data in a major discovery that means patients with unexplained kidney failure are finally getting a diagnosis.
Researchers identify molecular cues that make developing neurons remodel their connections.
At this very moment, the billions of neurons in your brain are using their trillions of connections to enable you to read and comprehend this sentence.
Now, by studying the neurons involved in the sense of smell, researchers from Kyushu University’s Faculty of Medical Sciences report a new mechanism behind the biomolecular bonsai that selectively strengthens these connections.
Advances with photoswitches could lead to a smartphone that’s soft and flexible and shaped like a hand so you can wear it as a glove, for example. Or a paper-thin computer screen that you can roll up like a window shade when you’re done using it. Or a TV as thin as wallpaper that you can paste on a wall and hardly know it’s there when you’re not watching it.
Photoswitches, which turn on and off in response to light, can be stitched together to replace the transistors used in electronic devices that control the flow of the electric current.
Commercial silicon transistors are brittle, nontransparent, and typically several microns thick, about the same thickness as a red blood cell. In contrast, photoswitches are one or two nanometers, about 1,000 times thinner. They can also be mounted on graphene, a transparent, flexible material.
A new fabrication process for helical metal nanoparticles provides a simpler, cheaper way to rapidly produce a material essential for biomedical and optical devices, according to a study by University of Michigan researchers.
Yale researchers have developed a cancer vaccine for dogs that nearly doubles their 12-month survival rate — and it might be a powerful treatment for humans with cancer, too.
Sick as a dog: In 2011, the FDA approved the first ever cancer immunotherapy — a treatment that supercharges the immune system to fight cancer — and today, oncologists have dozens of powerful immunotherapies in their arsenal, with more coming every year.
That’s not the case if the oncologist happens to treat dogs instead of people, though.
