Latest Journal of Visualized Experiments Stories

BUFFALO GROVE, Ill., Oct. 12, 2012 /PRNewswire/ -- In partnership with the Journal of Visualized Experiments (JoVE), Leica Microsystems is proud to offer science labs in North America the opportunity to publish a unique method or technique, which includes microscope-based imaging, in a peer-reviewed, video format. Publishing techniques in a peer-reviewed video format allows labs to: Sustain and pass on vital lab knowledge Share the most challenging techniques with other labs...

Journal demonstrates novel procedure in Antarcitca Lake Bonney in Antarctica is perennially covered in ice. It is exposed to severe environmental stresses, including minimal nutrients, low temperatures, extreme shade, and, during the winter, 24-hour darkness. But, for the single-celled organisms that live there, the lake is home. To study them, Dr. Rachel Morgan-Kiss from the University of Miami, Ohio, and her team went to Antarctica to sample the ice-covered lake. The article describing...

Up to 30% of the world's population is infected with Tuberculosis (TB), but in many areas of the world, TB diagnosis still relies on insensitive, poorly standardized, and time-consuming methods. A new diagnostic tool, endorsed by the World Health Organization (WHO), may change that. Dr. Thomas Bodmer shows how it's done in the Journal of Visualized Experiments (JoVE). Currently, TB is diagnosed through either a skin test, which produces a small bump on the patient's arm when administered...

Researchers are increasingly aware that fat in some parts of the body is more harmful than fat in other places. To help determine how obesity works, scientists turn to animal models and now, they are able to visualize how much fat their lab rats are carrying and where they are storing it. The method will be published in the April issue of the Journal of Visualized Experiments (JoVE). "One of the key benefits of this technique versus existing methods, like ex vivo analysis, is that this...

Have you ever been disappointed by a cantaloupe from the grocery store? Too ripe? Not ripe enough? Luckily for you, researchers from the University of California, Davis might have found a way to make imperfectly ripe fruit a thing of the past. The method will be published on March 30 in the Journal of Visualized Experiments (JoVE). "We are involved in a project geared towards developing rapid methods to evaluate ripeness and flavour of fruits," said paper-author Dr. Florence Negre-Zkharov....

According to the World Health Organization (WHO), one-third of the world's population is currently infected with tuberculosis bacteria. The bacteria is incredibly resistant to treatment, and despite its prevalence, very little is known about why it is so stress tolerant. But, researchers at the University of Pittsburgh have been developing a new way of culturing tuberculosis bacteria, which could lead to new insights and treatments. "This is a significant step forward in TB research," said...

In the US alone, at least 500,000 people suffer from Parkinson's disease, a neurological disorder that affects a person's ability to control his or her movement. New technology from the University of Bonn in Germany lets researchers observe the development of the brain cells responsible for the disease. Up until now, research into the brain cells responsible for Parkinson's disease has focused on the function and degeneration of these neurons in the adult and aging brain. The new tissue...

Quantifying how sore a person is after a long workout is a challenge for doctors and researchers, but scientists from Loma Linda and Asuza Pacific Universities think they may have figured it out. Their research article describing a new technique to measure muscle soreness will be published in the Journal of Visualized Experiments (JoVE). Delayed onset muscle soreness (DOMS) or exercise-induced muscle damage (EIMD) is one of the most common sports injuries, but without a reliable method of...

[ Watch the Video ] From a health care perspective, the best cigarette is no cigarette, but for the millions of people who try to quit smoking every year, researchers from Cornell University may have found a way to make cigarette smoking less toxic. Using natural antioxidant extracts in cigarette filters, the researchers were able to demonstrate that lycopene and grape seed extract drastically reduced the amount of cancer-causing free radicals passing through the filter. The research...

Recently, the accuracy of current methods of pain assessment in babies have been called into question. New research from London-area hospitals and the University of Oxford measures brain activity in infants to better understand their pain response. As every parent knows, interpreting what a baby is feeling is often incredibly difficult. Currently, pain in infants is assessed using the premature infant pain profile (PIPP), which is based on behavioral and physiological body reactions, such...
