Study: DBS reshapes neural circuits

UCSF professor Philip Starr published a paper suggesting that Deep Brain Stimulation works by reducing overly synchronized motor cortex activity. He believes that this explains why surgically implanted electrodes improve movement, tremor, and rigidity in Parkinson’s patients. Little is known about why and how DBS works.   This has held back efforts to improve the therapy. […]

Cheap, remote, smartphone molecular cancer diagnosis

A Harvard and Mass General developed device may bring rapid, accurate molecular diagnosis of cancer and other diseases to remote locations.  The smartphone-based device creates holograms to collect detailed microscopic images for digital analysis of the molecular composition of cells and tissues. The study’s authors believe that “because the system is compact, easy to operate, […]

Big Data, AI and personalized healthcare

With the goal of personalizing healthcare, improving outcomes and cutting costs, IBM’s Watson Health will aggregate massive amounts of disparate patient data.  The company has struck deals with Apple, Johnson & Johnson and Medtronic to collect and use more information from devices. To address privacy concerns, IBM is offering ways to strip personal information from wearables and […]

Nanoparticle treatment targets brain tumors

Tel Aviv University Professor Dan Peer is developing a nanoparticle-based process to target glioblastoma cells, previously considered untreatable. Nanoparticles were injected into tumors, acting as the drug delivery system. Nucleic acid, with interference RNAs, attached to receptors  expressed specifically on glioma cells, and stopped the activity of a key protein that regulates the rapid reproduction of […]

Breath test for head and neck cancer

EPFL researchers have developed a sensor that can identify the presence of a head and neck cancer through breath analysis. Nico de Rooij‘s micro-sensors  detect volatile organic compounds which vary in  presence and concentration depending on one’s health. The sensor includes a silicon disk covered by a polymer and suspended by four tiny “bridges” with integrated […]

Nanosensor cancer detection

Priscila Kosaka from the Microelectronic Institute of Madrid is in the early stages of developing a nanosensor to detect cancer from blood samples before symptoms appear.  It is not expected to be on the market for another 10 years, but could one day  eliminate the need for biopsies. Kosaka claims that the technology is 10 million […]
