21/10/2016Serotonin is a neurotransmitter that's partly responsible for feelings of happiness and for mood regulation in humans. This makes it a common target for antidepressants, which block serotonin from being reabsorbed by neurons after it has dispatched its signal, so more of it stays floating around the brain.
20/10/2016A diagnosis of pancreatic cancer is often a death sentence because chemotherapy and radiation have little impact on the disease. In the U.S. this year, some 53,000 new cases will be diagnosed, and 42,000 patients will die of the disease. But research now being reported in ACS Nano could eventually lead to a new type of treatment based on gold nanoparticles.
19/10/2016Washington State University researchers have developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch a cancer biomarker, producing lab quality results.
18/10/2016A new type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces.
14/10/2016A new imaging method, called "polarized nuclear imaging" - combining aspects of both magnetic resonance imaging and gamma-ray imaging - has potential for new types of high-resolution medical diagnostics as well as industrial and physics research applications.
13/10/2016Robots are usually expected to be rigid, fast and efficient. But researchers at EPFL's Reconfigurable Robotics Lab (RRL) have turned that notion on its head with their soft robots.
12/10/2016'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory.
11/10/2016New Berkeley Lab tool could shed light on how neurological diseases spread.
07/10/2016Many solid tumors are considered inoperable because they adhere to vital structures or the surgery would cause irreversible damages to the patients. In order to prevent the tumor growth or provide complete tumor resolution without surgery, chemotherapy and radiation are currently in clinical practice.
06/10/2016Blood testing is the standard option for checking glucose levels, but a new technology could allow non-invasive testing via a contact lens that samples glucose levels in tears.
