Drug Sponge

A group of researchers from University of California, Berkeley and University of California, San Francisco has recently developed a tiny polymer drug sponge, which is set to absorb excess chemotherapy agents from the bloodstream after they have reached the target. As reported in the journal ACS Central Science, the new drug sponge is aimed to minimize the ill side effects of toxic chemotherapy drugs which have potent effect against tumors,

Pacemaker

Engineers at the University of California, Berkeley developed a novel neurostimulator that can listen to and stimulate electric current simultaneously in the brain, potential for delivering effective treatments to patients with diseases such as Parkinson’s and epilepsy. The new wireless pacemaker device called ‘WAND’ functions like a pacemaker for the brain that monitors electrical activity of the brain as well as deliver electric stimulation when detecting something amiss. Wireless Pacemaker type

E-bandage

Skin is an important part of the body with remarkable ability to heal itself. However, in few cases, wound takes more time to heal or doesn’t heal at all, leading to increased risk of infection, scarring, and chronic pain. Recently, scientists at the University of Wisconsin-Madison in the United States have created a self-powered E-bandage that produces an electric field over an injury, allowing faster healing of skin wounds in

Neurons

In a recent study, researchers have discovered a novel way to monitor changes and observe ion fluxes, by examining the characteristics of water molecules surrounding the neural membranes. The research team at the Ecole Polytechnique Fédérale de Lausanne (EPFL) have tested the method on in vitro neurons of mouse and published their findings in the journal Nature Communications. Neurons in the brain communicate with each other through the electrochemical signals

Cardiovascular Diseases

A recent European study finds that excess fat around belly or the middle of the body (central obesity) is common in people who are at the high risk of cardiovascular diseases. EUROASPIRE V is a survey of diabetes and cardiovascular disease prevention which forms a part of the European Society of Cardiology research program. Findings of the survey are featured at the World Congress of Cardiology and Cardiovascular Health in

Youth Factor

In a recent study, researchers from Duke University Medical Center have been able to identify a youth factor in stem cells of bone marrow that can have a rejuvenating effect on tissues. Though painful, recovering from a broken bone is typically short-lived for a child. However, for an older person, it could possibly last longer or even be a life-threatening process. Researcher around the world have been making efforts to

Tweezers

While researchers across the world have been continuously learning and discovering more about the functions of cells, many questions still remain unanswered. A team of researchers at Imperial College London have successfully created nanoscale tweezers which are nearly 2000 times thinner than the width of a human hair. The nanotweezers can extract cellular components including single strands of DNA and other molecules without killing or causing damage to the living

Polio Vaccine

Polio, a disease that once paralyzed over 350,000 people around the world, has dropped to just about 407 cases in 2013 due to Polio vaccine, as reported by Centers for Disease Control and Prevention. Although the disease is on the brink of eradication with only 22 reported cases in 2017 worldwide, it still lurks in many countries as storage and transportation of the vaccine require refrigeration. A team of researchers at

Eye

Although scientists have been able to grow parts of an organ in a lab using stem cells, it is very different from creating a fully formed and functioning organ. To construct an actual organ such as for transplant, scientists need to think in three dimension. In order to cultivate the 3D perspectives, students of regenerative medicines and developmental biology need to better understand how cells fold and move to form

Biomaterial

Bioengineers at Penn State have discovered that ‘citrate’, a chemical based biomaterial on natural product of the bones and citrus fruit can provide extra energy essential for stem cells to construct new bone tissue. According to the researchers, new understanding of the mechanism that enables citrate to promote bone regeneration could help scientists around the world to develop biodegradable, citrate-releasing scaffolds to act as a template for bone development that
